  • The 20 Most Important Keyboard Shortcuts For Windows PCs

    - by Chris Hoffman
    Keyboard shortcuts are practically essential for using any type of PC. They’ll speed up almost everything you do. But long lists of keyboard shortcuts can quickly become overwhelming if you’re just getting started. This list will cover the most useful keyboard shortcuts that every Windows user should know. If you haven’t used keyboard shortcuts much, these will show you just how useful keyboard shortcuts can be. Windows Key + Search The Windows key is particularly important on Windows 8 — especially before Windows 8.1 — because it allows you to quickly return to the Start screen. On Windows 7, it opens the Start menu. Either way, you can start typing immediately after you press the Windows key to search for programs, settings, and files. For example, if you want to launch Firefox, you can press the Windows key, start typing the word Firefox, and press Enter when the Firefox shortcut appears. It’s a quick way to launch programs, open files, and locate Control Panel options without even touching your mouse and without digging through a cluttered Start menu. You can also use the arrow keys to select the shortcut you want to launch before pressing Enter. Copy, Cut, Paste Copy, Cut, and Paste are extremely important keyboard shortcuts for text-editing. If you do any typing on your computer, you probably use them. These options can be accessed using the mouse, either by right-clicking on selected text or opening the application’s Edit menu, but this is the slowest way to do it. After selecting some text, press Ctrl+C to copy it or Ctrl+X to cut it. Position the cursor where you want the text and use Ctrl+V to paste it. These shortcuts can save you a huge amount of time over using the mouse. Search the Current Page or File To quickly perform a search in the current application — whether you’re in a web browser, PDF viewer, document editor, or almost any other type of application — press Ctrl+F. The application’s search (or “Find”) feature will pop up, and you can instantly start typing a phrase you want to search for. You can generally press Enter to  go to the next appearance of the word or phrase in the document, quickly searching through it for what you’re interested in. Switch Between Applications and Tabs Rather than clicking buttons on your taskbar, Alt+Tab is a very quick way to switch between running applications. Windows orders the list of open windows by the order you accessed them, so if you’re only using two different applications, you can just press Alt+Tab to quickly switch between them. If switching between more than two windows, you’ll have to hold the Alt key and press Tab repeatedly to toggle through the list of open windows. If you miss the window you want, you can always press Alt+Shift+Tab to move through the list in reverse. To move between tabs in an application — such as the browser tabs in your web browser — press Ctrl+Tab. Ctrl+Shift+Tab will move through tabs in reverse. Quickly Print If you’re the kind of person who still prints things, you can quickly open the print window by pressing Ctrl+P. This can be faster than hunting down the Print option in every program you want to print something from. Basic Browser Shortcuts Web browser shortcuts can save you tons of time, too. Ctrl+T is a very useful one, as it will open a new tab with the address bar focused, so you can quickly press Ctrl +T, type a search phrase or web address, and press Enter to go there. To go back or forward while browsing, hold the Ctrl key and press the left or right arrow keys. If you’d just like to focus your web browser’s address bar so you can type a new web address or search without opening a new tab, press Ctrl + L. You can then start typing something and press Enter. Close Tabs and Windows To quickly close the current application, press Alt+F4. This works on the desktop and even in new Windows 8-style applications. To quickly close the current browser tab or document, press Ctrl+W. This will often close the current window if there are no other tabs open. Lock Your Computer When you’re done using your computer and want to step away, you may want to lock it. People won’t be able to log in and access your desktop unless they know your password. You can do this from the Start menu or Start screen, but the fastest way to lock your screen is by quickly pressing Windows Key + L before you get up. Access the Task Manager Ctrl+Alt+Delete will take you to a screen that allows you to quickly launch the Task Manager or perform other operations, such as signing out. This is particularly useful because if can be used to recover from situations where your computer doesn’t appear responsive or isn’t accepting input. For example, if a full-screen game becomes unresponsive, Ctrl+Alt+Delete will often allow you to escape from it and end it via the Task Manager. Windows 8 Shortcuts On Windows 8 PCs, there are other very important keyboard shortcuts. Windows Key + C will open your Charms bar, while Windows Key + Tab will open the new App Switcher. These keyboard shortcuts will allow you to avoid the hot corners, which can be tedious to use with a mouse. On the desktop side, Windows Key + D will take you back to the desktop from anywhere. Windows Key + X will open a special “power user menu” that gives you quick access to options that are hidden in the new Windows 8 interface, including Shut Down, Restart, and Control Panel. If you’re interested in learning more keyboard shortcuts, be sure to check our longer lists of 47 keyboard shortcuts that work in all web browsers and 42+ keyboard shortcuts to speed up text-editing.

  • 3D picking lwjgl

    - by Wirde
    I have written some code to preform 3D picking that for some reason dosn't work entirely correct! (Im using LWJGL just so you know.) I posted this at stackoverflow at first but after researching some more in to my problem i found this neat site and tought that you guys might be more qualified to answer this question. This is how the code looks like: if(Mouse.getEventButton() == 1) { if (!Mouse.getEventButtonState()) { Camera.get().generateViewMatrix(); float screenSpaceX = ((Mouse.getX()/800f/2f)-1.0f)*Camera.get().getAspectRatio(); float screenSpaceY = 1.0f-(2*((600-Mouse.getY())/600f)); float displacementRate = (float)Math.tan(Camera.get().getFovy()/2); screenSpaceX *= displacementRate; screenSpaceY *= displacementRate; Vector4f cameraSpaceNear = new Vector4f((float) (screenSpaceX * Camera.get().getNear()), (float) (screenSpaceY * Camera.get().getNear()), (float) (-Camera.get().getNear()), 1); Vector4f cameraSpaceFar = new Vector4f((float) (screenSpaceX * Camera.get().getFar()), (float) (screenSpaceY * Camera.get().getFar()), (float) (-Camera.get().getFar()), 1); Matrix4f tmpView = new Matrix4f(); Camera.get().getViewMatrix().transpose(tmpView); Matrix4f invertedViewMatrix = (Matrix4f)tmpView.invert(); Vector4f worldSpaceNear = new Vector4f(); Matrix4f.transform(invertedViewMatrix, cameraSpaceNear, worldSpaceNear); Vector4f worldSpaceFar = new Vector4f(); Matrix4f.transform(invertedViewMatrix, cameraSpaceFar, worldSpaceFar); Vector3f rayPosition = new Vector3f(worldSpaceNear.x, worldSpaceNear.y, worldSpaceNear.z); Vector3f rayDirection = new Vector3f(worldSpaceFar.x - worldSpaceNear.x, worldSpaceFar.y - worldSpaceNear.y, worldSpaceFar.z - worldSpaceNear.z); rayDirection.normalise(); Ray clickRay = new Ray(rayPosition, rayDirection); Vector tMin = new Vector(), tMax = new Vector(), tempPoint; float largestEnteringValue, smallestExitingValue, temp, closestEnteringValue = Camera.get().getFar()+0.1f; Drawable closestDrawableHit = null; for(Drawable d : this.worldModel.getDrawableThings()) { // Calcualte AABB for each object... needs to be moved later... firstVertex = true; for(Surface surface : d.getSurfaces()) { for(Vertex v : surface.getVertices()) { worldPosition.x = (v.x+d.getPosition().x)*d.getScale().x; worldPosition.y = (v.y+d.getPosition().y)*d.getScale().y; worldPosition.z = (v.z+d.getPosition().z)*d.getScale().z; worldPosition = worldPosition.rotate(d.getRotation()); if (firstVertex) { maxX = worldPosition.x; maxY = worldPosition.y; maxZ = worldPosition.z; minX = worldPosition.x; minY = worldPosition.y; minZ = worldPosition.z; firstVertex = false; } else { if (worldPosition.x > maxX) { maxX = worldPosition.x; } if (worldPosition.x < minX) { minX = worldPosition.x; } if (worldPosition.y > maxY) { maxY = worldPosition.y; } if (worldPosition.y < minY) { minY = worldPosition.y; } if (worldPosition.z > maxZ) { maxZ = worldPosition.z; } if (worldPosition.z < minZ) { minZ = worldPosition.z; } } } } // ray/slabs intersection test... // clickRay.getOrigin().x + clickRay.getDirection().x * f = minX // clickRay.getOrigin().x - minX = -clickRay.getDirection().x * f // clickRay.getOrigin().x/-clickRay.getDirection().x - minX/-clickRay.getDirection().x = f // -clickRay.getOrigin().x/clickRay.getDirection().x + minX/clickRay.getDirection().x = f largestEnteringValue = -clickRay.getOrigin().x/clickRay.getDirection().x + minX/clickRay.getDirection().x; temp = -clickRay.getOrigin().y/clickRay.getDirection().y + minY/clickRay.getDirection().y; if(largestEnteringValue < temp) { largestEnteringValue = temp; } temp = -clickRay.getOrigin().z/clickRay.getDirection().z + minZ/clickRay.getDirection().z; if(largestEnteringValue < temp) { largestEnteringValue = temp; } smallestExitingValue = -clickRay.getOrigin().x/clickRay.getDirection().x + maxX/clickRay.getDirection().x; temp = -clickRay.getOrigin().y/clickRay.getDirection().y + maxY/clickRay.getDirection().y; if(smallestExitingValue > temp) { smallestExitingValue = temp; } temp = -clickRay.getOrigin().z/clickRay.getDirection().z + maxZ/clickRay.getDirection().z; if(smallestExitingValue < temp) { smallestExitingValue = temp; } if(largestEnteringValue > smallestExitingValue) { //System.out.println("Miss!"); } else { if (largestEnteringValue < closestEnteringValue) { closestEnteringValue = largestEnteringValue; closestDrawableHit = d; } } } if(closestDrawableHit != null) { System.out.println("Hit at: (" + clickRay.setDistance(closestEnteringValue).x + ", " + clickRay.getCurrentPosition().y + ", " + clickRay.getCurrentPosition().z); this.worldModel.removeDrawableThing(closestDrawableHit); } } } I just don't understand what's wrong, the ray are shooting and i do hit stuff that gets removed but the result of the ray are verry strange it sometimes removes the thing im clicking at, sometimes it removes things thats not even close to what im clicking at, and sometimes it removes nothing at all. Edit: Okay so i have continued searching for errors and by debugging the ray (by painting smal dots where it travles) i can now se that there is something oviously wrong with the ray that im sending out... it has its origin near the world center (nearer or further away depending on where on the screen im clicking) and always shots to the same position no matter where I direct my camera... My initial toughts is that there might be some error in the way i calculate my viewMatrix (since it's not possible to get the viewmatrix from the gluLookAt method in lwjgl; I have to build it my self and I guess thats where the problem is at)... Edit2: This is how i calculate it currently: private double[][] viewMatrixDouble = {{0,0,0,0}, {0,0,0,0}, {0,0,0,0}, {0,0,0,1}}; public Vector getCameraDirectionVector() { Vector actualEye = this.getActualEyePosition(); return new Vector(lookAt.x-actualEye.x, lookAt.y-actualEye.y, lookAt.z-actualEye.z); } public Vector getActualEyePosition() { return eye.rotate(this.getRotation()); } public void generateViewMatrix() { Vector cameraDirectionVector = getCameraDirectionVector().normalize(); Vector side = Vector.cross(cameraDirectionVector, this.upVector).normalize(); Vector up = Vector.cross(side, cameraDirectionVector); viewMatrixDouble[0][0] = side.x; viewMatrixDouble[0][1] = up.x; viewMatrixDouble[0][2] = -cameraDirectionVector.x; viewMatrixDouble[1][0] = side.y; viewMatrixDouble[1][1] = up.y; viewMatrixDouble[1][2] = -cameraDirectionVector.y; viewMatrixDouble[2][0] = side.z; viewMatrixDouble[2][1] = up.z; viewMatrixDouble[2][2] = -cameraDirectionVector.z; /* Vector actualEyePosition = this.getActualEyePosition(); Vector zaxis = new Vector(this.lookAt.x - actualEyePosition.x, this.lookAt.y - actualEyePosition.y, this.lookAt.z - actualEyePosition.z).normalize(); Vector xaxis = Vector.cross(upVector, zaxis).normalize(); Vector yaxis = Vector.cross(zaxis, xaxis); viewMatrixDouble[0][0] = xaxis.x; viewMatrixDouble[0][1] = yaxis.x; viewMatrixDouble[0][2] = zaxis.x; viewMatrixDouble[1][0] = xaxis.y; viewMatrixDouble[1][1] = yaxis.y; viewMatrixDouble[1][2] = zaxis.y; viewMatrixDouble[2][0] = xaxis.z; viewMatrixDouble[2][1] = yaxis.z; viewMatrixDouble[2][2] = zaxis.z; viewMatrixDouble[3][0] = -Vector.dot(xaxis, actualEyePosition); viewMatrixDouble[3][1] =-Vector.dot(yaxis, actualEyePosition); viewMatrixDouble[3][2] = -Vector.dot(zaxis, actualEyePosition); */ viewMatrix = new Matrix4f(); viewMatrix.load(getViewMatrixAsFloatBuffer()); } Would be verry greatfull if anyone could verify if this is wrong or right, and if it's wrong; supply me with the right way of doing it... I have read alot of threads and documentations about this but i can't seam to wrapp my head around it... Edit3: Okay with the help of Byte56 (thanks alot for the help) i have now concluded that it's not the viewMatrix that is the problem... I still get the same messedup result; anyone that think that they can find the error in my code, i certenly can't, have bean working on this for 3 days now :(

  • C#/.NET Little Wonders &ndash; Cross Calling Constructors

    - by James Michael Hare
    Just a small post today, it’s the final iteration before our release and things are crazy here!  This is another little tidbit that I love using, and it should be fairly common knowledge, yet I’ve noticed many times that less experienced developers tend to have redundant constructor code when they overload their constructors. The Problem – repetitive code is less maintainable Let’s say you were designing a messaging system, and so you want to create a class to represent the properties for a Receiver, so perhaps you design a ReceiverProperties class to represent this collection of properties. Perhaps, you decide to make ReceiverProperties immutable, and so you have several constructors that you can use for alternative construction: 1: // Constructs a set of receiver properties. 2: public ReceiverProperties(ReceiverType receiverType, string source, bool isDurable, bool isBuffered) 3: { 4: ReceiverType = receiverType; 5: Source = source; 6: IsDurable = isDurable; 7: IsBuffered = isBuffered; 8: } 9: 10: // Constructs a set of receiver properties with buffering on by default. 11: public ReceiverProperties(ReceiverType receiverType, string source, bool isDurable) 12: { 13: ReceiverType = receiverType; 14: Source = source; 15: IsDurable = isDurable; 16: IsBuffered = true; 17: } 18:  19: // Constructs a set of receiver properties with buffering on and durability off. 20: public ReceiverProperties(ReceiverType receiverType, string source) 21: { 22: ReceiverType = receiverType; 23: Source = source; 24: IsDurable = false; 25: IsBuffered = true; 26: } Note: keep in mind this is just a simple example for illustration, and in same cases default parameters can also help clean this up, but they have issues of their own. While strictly speaking, there is nothing wrong with this code, logically, it suffers from maintainability flaws.  Consider what happens if you add a new property to the class?  You have to remember to guarantee that it is set appropriately in every constructor call. This can cause subtle bugs and becomes even uglier when the constructors do more complex logic, error handling, or there are numerous potential overloads (especially if you can’t easily see them all on one screen’s height). The Solution – cross-calling constructors I’d wager nearly everyone knows how to call your base class’s constructor, but you can also cross-call to one of the constructors in the same class by using the this keyword in the same way you use base to call a base constructor. 1: // Constructs a set of receiver properties. 2: public ReceiverProperties(ReceiverType receiverType, string source, bool isDurable, bool isBuffered) 3: { 4: ReceiverType = receiverType; 5: Source = source; 6: IsDurable = isDurable; 7: IsBuffered = isBuffered; 8: } 9: 10: // Constructs a set of receiver properties with buffering on by default. 11: public ReceiverProperties(ReceiverType receiverType, string source, bool isDurable) 12: : this(receiverType, source, isDurable, true) 13: { 14: } 15:  16: // Constructs a set of receiver properties with buffering on and durability off. 17: public ReceiverProperties(ReceiverType receiverType, string source) 18: : this(receiverType, source, false, true) 19: { 20: } Notice, there is much less code.  In addition, the code you have has no repetitive logic.  You can define the main constructor that takes all arguments, and the remaining constructors with defaults simply cross-call the main constructor, passing in the defaults. Yes, in some cases default parameters can ease some of this for you, but default parameters only work for compile-time constants (null, string and number literals).  For example, if you were creating a TradingDataAdapter that relied on an implementation of ITradingDao which is the data access object to retreive records from the database, you might want two constructors: one that takes an ITradingDao reference, and a default constructor which constructs a specific ITradingDao for ease of use: 1: public TradingDataAdapter(ITradingDao dao) 2: { 3: _tradingDao = dao; 4:  5: // other constructor logic 6: } 7:  8: public TradingDataAdapter() 9: { 10: _tradingDao = new SqlTradingDao(); 11:  12: // same constructor logic as above 13: }   As you can see, this isn’t something we can solve with a default parameter, but we could with cross-calling constructors: 1: public TradingDataAdapter(ITradingDao dao) 2: { 3: _tradingDao = dao; 4:  5: // other constructor logic 6: } 7:  8: public TradingDataAdapter() 9: : this(new SqlTradingDao()) 10: { 11: }   So in cases like this where you have constructors with non compiler-time constant defaults, default parameters can’t help you and cross-calling constructors is one of your best options. Summary When you have just one constructor doing the job of initializing the class, you can consolidate all your logic and error-handling in one place, thus ensuring that your behavior will be consistent across the constructor calls. This makes the code more maintainable and even easier to read.  There will be some cases where cross-calling constructors may be sub-optimal or not possible (if, for example, the overloaded constructors take completely different types and are not just “defaulting” behaviors). You can also use default parameters, of course, but default parameter behavior in a class hierarchy can be problematic (default values are not inherited and in fact can differ) so sometimes multiple constructors are actually preferable. Regardless of why you may need to have multiple constructors, consider cross-calling where you can to reduce redundant logic and clean up the code.   Technorati Tags: C#,.NET,Little Wonders

  • Azure Mobile Services: available modules

    - by svdoever
    Azure Mobile Services has documented a set of objects available in your Azure Mobile Services server side scripts at their documentation page Mobile Services server script reference. Although the documented list is a nice list of objects for the common things you want to do, it will be sooner than later that you will look for more functionality to be included in your script, especially with the new provided feature that you can now create your custom API’s. If you use GIT it is now possible to add any NPM module (node package manager module, say the NuGet of the node world), but why include a module if it is already available out of the box. And you can only use GIT with Azure Mobile Services if you are an administrator on your Azure Mobile Service, not if you are a co-administrator (will be solved in the future). Until now I did some trial and error experimentation to test if a certain module was available. This is easiest to do as follows:   Create a custom API, for example named experiment. In this API use the following code: exports.get = function (request, response) { var module = "nonexistingmodule"; var m = require(module); response.send(200, "Module '%s' found.", module); }; You can now test your service with the following request in your browser: https://yourservice.azure-mobile.net/api/experiment If you get the result: {"code":500,"error":"Error: Internal Server Error"} you know that the module does not exist. In your logs you will find the following error: Error in script '/api/experiment.json'. Error: Cannot find module 'nonexistingmodule' [external code] atC:\DWASFiles\Sites\yourservice\VirtualDirectory0\site\wwwroot\App_Data\config\scripts\api\experiment.js:3:13[external code] If you require an existing (undocumented) module like the OAuth module in the following code, you will get success as a result: exports.get = function (request, response) { var module = "oauth"; var m = require(module); response.send(200, "Module '" + module + "' found."); }; If we look at the standard node.js documentation we see an extensive list of modules that can be used from your code. If we look at the list of files available in the Azure Mobile Services platform as documented in the blog post Azure Mobile Services: what files does it consist of? we see a folder node_modules with many more modules are used to build the Azure Mobile Services functionality on, but that can also be utilized from your server side node script code: apn - An interface to the Apple Push Notification service for Node.js. dpush - Send push notifications to Android devices using GCM. mpns - A Node.js interface to the Microsoft Push Notification Service (MPNS) for Windows Phone. wns - Send push notifications to Windows 8 devices using WNS. pusher - Node library for the Pusher server API (see also: http://pusher.com/) azure - Windows Azure Client Library for node. express - Sinatra inspired web development framework. oauth - Library for interacting with OAuth 1.0, 1.0A, 2 and Echo. Provides simplified client access and allows for construction of more complex apis and OAuth providers. request - Simplified HTTP request client. sax - An evented streaming XML parser in JavaScript sendgrid - A NodeJS implementation of the SendGrid Api. sqlserver – In node repository known as msnodesql - Microsoft Driver for Node.js for SQL Server. tripwire - Break out from scripts blocking node.js event loop. underscore - JavaScript's functional programming helper library. underscore.string - String manipulation extensions for Underscore.js javascript library. xml2js - Simple XML to JavaScript object converter. xmlbuilder - An XML builder for node.js. As stated before, many of these modules are used to provide the functionality of Azure Mobile Services platform, and in general should not be used directly. On the other hand, I needed OAuth badly to authenticate to the new v1.1 services of Twitter, and was very happy that a require('oauth') and a few lines of code did the job. Based on the above modules and a lot of code in the other javascript files in the Azure Mobile Services platform a set of global objects is provided that can be used from your server side node.js script code. In future blog posts I will go into more details with respect to how this code is built-up, all starting at the node.js express entry point app.js.

  • Simple Scripting for your Exalogic Storage

    - by Trond Strømme
    As part of my job in Oracle ACS (Advanced Customer Services) I'm handling lots of different systems and customers. Among the recent systems I worked with have been Oracle's Exalogic engineered systems. One of the things I'd never had much exposure to as a system developer/architect/middleware guy/Java dude has been storage; outside of consuming it for my photography needs.. Well, I'm always ready for a new challenge... I'd downloaded the 7000 series storage simulator when it was released in the good old Sun days, found it fun and instructive to play around with, but as I never touched storage in any way (besides consuming it..) I forgot about it. A couple of years ago when I started working with Exalogic engineered systems it again came into light as an invaluable learning and testing tool for the embedded storage in an Exalogic;  Oracle's Sun ZFS Storage 7320 Appliance.  aaaanyway... I've been "booted" into a part-time role as the interim storage/system admin/middleware/Java guy for a client and found I needed to create the occasional report or summary or whatever.. of what's using the storage in the 7320 (as default configured for an Exalogic, 40T of disk in a mirrored configuration, yielding 18T of actual space.) Reading the nice documentation and some articles on the Oracle Technology Network I saw great possibilities with the embedded ECMAScript3/JavaScript engine in the 7000 series.  In my personal opinion anyone who's dealing with Exalogic administration, or exposed to any of the 7000 series of storage appliances and servers that Oracle offers should have a VirtualBox instance of it kicking around. For development and testing it's a fantastic tool. (It can save you from explaining (most) of the embarrassing FAILS you can do if you test something in a production system to your management...) So download, and install.  A small sidestep, if after firing up the 7000 series simulator in VirtualBox you've forgotten what it's IP address is, the following will sort you out if you log in directly via the running VirtualBox VM. So in my case I can ssh to 192.168.56.101 or point a browser to https://192.168.56.101:215 to log into the storage appliance. One simple way of executing a script on the 7320 is to ssh to the device and redirecting a file with the script in it to ssh. ssh [email protected] < myscript.js One question I got from my client and the people who will take over the systems was: "how can we see the quotas and allocations for all projects/shares in one easy go so we don't have to go navigating around in the BUI for all the hundreds of shares the 7320 is hosting just to check if anything is running dry?" Easy! JavaScript time, VirtualBox and emacs! //NOTE! this script is available 'as is' It has ben run on a couple of 7320's, (running 2010.08.17.3.0,1-1.25 & // 2011.04.24.1.0,1-1.8) a 7420 and the VB image, but I personally //offer no guarantee whatsoever that it won't make your server topple, catch fire or in any way go pear shaped.. //run at your own risk or learn from my code and or mistakes.. script run('cd /'); run('shares'); //get all projects: proj = list(); function spaceToGig(bytes){ return bytes/1073741824; //convert bytes to GB } function fullInPercent(quota, space_data){ tmp = (space_data/quota)*100; return tmp; } //print header, slightly good looking printf(" %s/%-15s %8s(GB) %7s(GB) %5s(GB) %7s(GB) %3s\n","Project", "Share","Quota","Ref", "Snap", "Total","%full"); printf("-------------------------------------------------------------------------------\n") //for each project, get all shares. check for quota and calculate percentage and human readable figures.. for (i=0;i<proj.length;i++){ run('select ' + proj[i]); //get all shares for a project var pshares = list(); //for each share get quota properties for (j=0;j<pshares.length;j++){ run('select ' + pshares[j]); quota = get('quota'); //properties associated with a share or inherited from a project spaceData = get('space_data'); spaceSnap = get('space_snapshots'); spaceTotal = get('space_total'); if(quota>0){ //has quota printf(" %s/%-15s \t%4.2fGB\t%.2fGB\t%.2fGB\t%.2fGB\t%5.2f%%\n",proj[i], pshares[j],spaceToGig(quota),spaceToGig(spaceData),spaceToGig(spaceSnap),spaceToGig(spaceTotal),fullInPercent(quota,spaceTotal)); }else{ //no quota printf(" %s/%-15s \t%8s\t%.2fGB\t%.2fGB\t%.2fGB\t%s\n",proj[i],pshares[j], "N/A", spaceToGig(spaceData),spaceToGig(spaceSnap),spaceToGig(spaceTotal),"N/A"); } run('cd ..'); } run('done'); } The resulting output should look something like this: Project/Share Quota(GB) Ref(GB) Snap(GB) Total(GB) %full ------------------------------------------------------------------------------- ACSExalogicSystem/domains N/A 0.04GB 0.00GB 0.04GB N/A ACSExalogicSystem/logs N/A 0.01GB 0.00GB 0.01GB N/A ACSExalogicSystem/nodemgrs N/A 0.00GB 0.00GB 0.00GB N/A ACSExalogicSystem/stores N/A 0.04GB 0.00GB 0.04GB N/A ***_dev/FMW_***_1 133GB 4.24GB 0.01GB 4.25GB 3.19% ***_dev/FMW_***_2 N/A 4.25GB 0.01GB 4.26GB N/A ***_dev/applications 10GB 0.00GB 0.00GB 0.00GB 0.00% ***_dev/domains 50GB 10.75GB 3.55GB 14.30GB 28.61% ***_dev/logs 20GB 0.32GB 0.01GB 0.33GB 1.66% ***_dev/softwaredepot 20GB 4.15GB 0.00GB 4.15GB 20.73% ***_dev/stores 20GB 0.01GB 0.00GB 0.01GB 0.05% ###_dev/FMW_###_1 400GB 17.63GB 0.12GB 17.75GB 4.44% ###_dev/applications N/A 0.00GB 0.00GB 0.00GB N/A ###_dev/domains 120GB 14.21GB 5.53GB 19.74GB 16.45% ###_dev/logs 15GB 0.00GB 0.00GB 0.00GB 0.00% ###_dev/softwaredepot 250GB 73.55GB 0.02GB 73.57GB 29.43% …snip My apologies if the output is a bit mis-aligned here and there, I only bothered making it look good, not perfect :/ I also removed some of the project names (*,#)

  • My First Weeks at Red Gate

    - by Jess Nickson
    Hi, my name’s Jess and early September 2012 I started working at Red Gate as a Software Engineer down in The Agency (the Publishing team). This was a bit of a shock, as I didn’t think this team would have any developers! I admit, I was a little worried when it was mentioned that my role was going to be different from normal dev. roles within the company. However, as luck would have it, I was placed within a team that was responsible for the development and maintenance of Simple-Talk and SQL Server Central (SSC). I felt rather unprepared for this role. I hadn’t used many of the technologies involved and of those that I had, I hadn’t looked at them for quite a while. I was, nevertheless, quite excited about this turn of events. As I had predicted, the role has been quite challenging so far. I expected that I would struggle to get my head round the large codebase already in place, having never used anything so much as a fraction of the size of this before. However, I was perhaps a bit naive when it came to how quickly things would move. I was required to start learning/remembering a number of different languages and technologies within time frames I would never have tried to set myself previously. Having said that, my first week was pretty easy. It was filled with meetings that were designed to get the new starters up to speed with the different departments, ideals and rules within the company. I also attended some lightning talks being presented by other employees, which were pretty useful. These occur once a fortnight and normally consist of around four speakers. In my spare time, we set up the Simple-Talk codebase on my computer and I started exploring it and worked on my first feature – redirecting requests for URLs that used incorrect casing! It was also during this time that I was given my first introduction to test-driven development (TDD) with Michael via a code kata. Although I had heard of the general ideas behind TDD, I had definitely never tried it before. Indeed, I hadn’t really done any automated testing of code before, either. The session was therefore very useful and gave me insights as to some of the coding practices used in my team. Although I now understand the importance of TDD, it still seems odd in my head and I’ve yet to master how to sensibly step up the functionality of the code a bit at a time. The second week was both easier and more difficult than the first. I was given a new project to work on, meaning I was no longer using the codebase already in place. My job was to take some designs, a WordPress theme, and some initial content and build a page that allowed users of the site to read provided resources and give feedback. This feedback could include their thoughts about the resource, the topics covered and the page design itself. Although it didn’t sound the most challenging of projects when compared to fixing bugs in our current codebase, it nevertheless provided a few sneaky problems that had me stumped. I really enjoyed working on this project as it allowed me to play around with HTML, CSS and JavaScript; all things that I like working with but rarely have a chance to use. I completed the aims for the project on time and was happy with the final outcome – though it still needs a good designer to take a look at it! I am now into my third week at Red Gate and I have temporarily been pulled off the website from week 2. I am again back to figuring out the Simple-Talk codebase. Monday provided me with the chance to learn a bunch of new things: system level testing, Selenium and Python. I was set the challenge of testing a bug fix dealing with the search bars in Simple-Talk. The exercise was pretty fun, although Mike did have to point me in the right direction when I started making the tests a bit too complex. The rest of the week looks set to be focussed on pair programming with Mike as we work together on a new feature. I look forward to the challenges that still face me and hope that I will be able to get up to speed quickly. *fingers crossed*

  • Planning an Event&ndash;SPS NYC

    - by MOSSLover
    I bet some of you were wondering why I am not going to any events for the most part in June and July (aside from volunteering at SPS Chicago).  Well I basically have no life for the next 2 months.  We are approaching the 11th hour of SharePoint Saturday New York City.  The event is slated to have 350 to 400 attendees.  This is second year in a row I’ve helped run it with Jason Gallicchio.  It’s amazingly crazy how much effort this event requires versus Kansas City.  It’s literally 2x the volume of attendees, speakers, and sponsors plus don’t even get me started about volunteers.  So here is a bit of the break down… We have 30 volunteers+ that Tasha Scott from the Hampton Roads Area will be managing the day of the event to do things like timing the speakers, handing out food, making sure people don’t walk into the event that did not sign up until we get a count for fire code, registering people, watching the sharpees, watching the prizes, making sure attendees get to the right place,  opening and closing the partition in the big room, moving chairs, moving furniture, etc…Then there is Jason, Greg, and I who will be making sure that the speakers, sponsors, and everything is going smoothly in the background.  We need to make sure that everything is setup properly and in the right spot.  We also need to make sure signs are printed, schedules are created, bags are stuffed with sponsor material.  Plus we need to send out emails to sponsors reminding them to send us the right information to post on the site for charity sessions, send us boxes with material to stuff bags, and we need to make sure that Michael Lotter gets there information for invoicing.  We also need to check that Michael has invoiced everyone and who has paid, because we can’t order anything for the event without money.  Once people have paid we need to setup food orders, speaker and volunteer dinners, buy prizes, buy bags, buy speakers/volunteer/organizer shirts, etc…During this process we need all the abstracts from speakers, all the bios, pictures, shirt sizes, and other items so we can create schedules and order items.  We also need to keep track of who is attending the dinner the night before for volunteers and speakers and make sure we don’t hit capacity.  Then there is attendee tracking and making sure that we don’t hit too many attendees.  We need to make sure that attendees know where to go and what to do.  We have to make all kinds of random supply lists during this process and keep on track with a variety of lists and emails plus conference calls.  All in all it’s a lot of work and I am trying to keep track of it all the top so that we don’t duplicate anything or miss anything.  So basically all in all if you don’t see me around for another month don’t worry I do exist. Right now if you look at what I’m doing I am traveling every Monday morning and Thursday night back and forth to Washington DC from New Jersey.  Every night I am working on organizational stuff for SharePoint Saturday New York City.  Every Tuesday night we are running an event conference call.  Every weekend I am either with family or my boyfriend and cat trying hard not to touch the event.  So all my time is pretty much work, event, and family/boyfriend.  I have 0 bandwidth for anything in the community.  If you compound that with my severe allergy problems in DC and a doctor’s appointment every month plus a new med once a week I’m lucky I am still standing and walking.  So basically once July 30th hits hopefully Jason Gallicchio, Greg Hurlman, and myself will be able to breathe a little easier.  If I forget to do this thank you Greg and Jason.  Thank you Tom Daly.  Thank you Michael Lotter.  Thank you Tasha Scott.  Thank you Kevin Griffin.  Thank you all the volunteers, speakers, sponsors, and attendees who will and have made this event a success.  Hopefully, we have enough time until next year to regroup, recharge, and make the event grow bigger in a different venue.  Awesome job everyone we sole out within 3 days of registration and we still have several weeks to go.  Right now the waitlist is at 49 people with room to grow.  If you attend the event thank all these guys I mentioned above for making it possible.  It’s going to be awesome I know it but I probably won’t remember half of it due to the blur of things that we will all be taking care of the day of the event.  Catch you all in the end of July/Early August where I will attempt to post something useful and clever and possibly while wearing a fez.

  • Come meet our Interns in Dublin

    - by klaudia.drulis
    Oracle Worldwide Product Translation Group (WPTG) provides solutions for all Oracle product and Content translation requirements. WPTG is a global organisation with its headquarters in Ireland and employees in Oracle offices worldwide. WPTG offer expertise in fields such as process engineering, tools development, linguistic quality, terminology, global product release, financial and vendor management. WPTG provides translation solution for over 40 languages including Asia Pacific, European, American and Middle Eastern languages. WPTG first introduced an intern program over 10 years ago and it has become a key component of our teams structure. The majority of Interns are sourced from a Computer Science related course, these Interns joining the engineering team. Others are sourced from Business courses and work within the Business / Project management area. The intern program allows us to maintain ties with current course curriculum and brings fresh energy and perspective into our Organisation. Four of the full time staff working in Dublin today joined us originally as Interns and subsequently were offered permanent positions. Come Meet some of our 2010 Interns, Come and see what Darragh, Anthony, Caoimhe, James and Artemij thought about working within the WPTG at Oracle: Darragh “Oracle has been a fun, challenging work placement for me. From day one I was treated as a full member of staff, this was both comforting and a little bit scary. The responsibilities stack up but I found I was able to keep on top of everything and even make improvements to how we handle a few things thanks to a great team and a very supportive manager. There’s a very positive atmosphere in work that’s really conducive to getting a lot of work done. Ideas seem to be the central hub in my line of business so all of my ideas and innovations were greeted with enthusiasm. Oracle has given me a fantastic opportunity and I urge you to grab it with both hands, you’ll find that you’re with a set of like minded people from all works of life that make work both interesting and fun. Even when the pressure is on you know that you can always get help and advice from someone nearby. My last word of advice is don’t be afraid to stick your neck out, everyone here is willing to learn, try something new and innovate, your voice will be heard and who knows, you could end up having a large impact on Oracle and your career.” Anthony “I had a great experience working with Oracle, from day one I was treated like a full member of staff with responsibilities of my own. I found that the more I put into the work the more I got out from the experience. Volunteering and being willing to face challenges have made this a more exciting placement. I am given a lot of leeway to do my own projects and so I’ve found that I am really enjoying my time here.” Caoimhe “I am currently spending my year of placement within the Release Management Team in the WPTG. My main role is to handle the finance process of all translation projects under 100k which includes creating workspecs and PO's, sending out kits, dealing with vendor queries and handling the invoicing and payment part. I am really enjoying my time here at Oracle, everyone is very open and friendly and willing to help you out with any questions you may have. I would definitely be interested in returning to Oracle after I graduate!” James “I am currently on a 12 month placement with Oracle, working as part of the Worldwide Product Translation Group in the Business Management. The Business Management team provides a global view on WPTG’s vendor and business strategy and is an interface into WPTG for new business. The business management team work together to support the external translation partner network. My role is to support the Business Management team and also to work on various projects when the need arises. This involves working with translation vendors and working with other Oracle employees worldwide. I am really enjoying my time working for Oracle, at times it can be challenging bit also very rewarding. I would recommend any student wanting to undertake a placement year to apply to Oracle, I made some great friends and I will never forget my time in Dublin.” Artemij “From working within Oracle, I have truly understood what "career path" is, and what opportunities a large corporation like Oracle can offer. Without any illusions, the work itself is exciting, sometimes challenging, tests your ability to handle pressure, to make decisions and take responsibility, to learn quickly and cooperate efficiently in order to solve a problem. I have learned a lot about myself. What I am good at, where and what I can do better. My placement at Oracle has allowed me to get a clearer picture of what I want, and which door I am going to open after college.

  • The Arab HEUG is now a reality, and other random thoughts

    - by user9147039
    I just returned from Doha, Qatar where the first of its kind HEUG (Higher Education User Group) meeting for institutions in the Middle East and North Africa was held at Qatar University and jointly hosted by Damman University from Saudi Arabia. Over 80 delegates attended including representation from education institutions in Oman, Saudi Arabia, Lebanon, and Qatar. There are many other regional HEUG organizations in place (in Australia/New Zealand, APAC, EMEA, as well as smaller regional HEUG’s in the Netherlands, South Africa, and in regions of the US), but it was truly an accomplishment to see this Middle East/North Africa group organize and launch their chapter with a meeting of this quality. To be known as the Arab HEUG going forward, I am excited about the prospects for sharing between the institutions and for the growth of Oracle solutions in the region. In particular the hosts for the event (Qatar University) did a masterful job with logistics and organization, and the quality of the event was a testament to their capabilities. Among the more interesting and enlightening presentations I attended were one from Dammam University on the lessons learned from their implementation of Campus Solutions and transition off of Banner, as well as the use by Qatar University E-business Suite for grants management (both pre-and post-award). The most notable fact coming from this latter presentation was the fit (89%) of e-Business Suite Grants to the university’s requirements. In a few weeks time we will be convening the 5th meeting of the Oracle Education & Research Industry Strategy Council in Redwood Shores (5th since my advent into my current role). The main topics of discussion will be around our Higher Education Applications Strategy for the future (including cloud approaches to ERP (HCM, Finance, and Student Information Systems), how some cases studies on the benefits of leveraging delivered functionality and extensibility in the software (versus customization). On the second day of the event we will turn our attention to Oracle in Research and also budgeting and planning in higher education. Both of these sessions will include significant participation from council members in the form of panel discussions. Our EVP’s for Systems (John Fowler) and for Global Cloud Services and North America application sales (Joanne Olson) will join us for the discussion. I recently read a couple of articles that were surprising to me. The first was from Inside Higher Ed on October 15 entitled, “As colleges prepare for major software upgrades, Kuali tries to woo them from corporate vendors.” It continues to disappointment that after all this time we are still debating whether it is better to build enterprise software through open or community source initiatives when fully functional, flexible, supported, and widely adopted options exist in the marketplace. Over a decade or more ago when these solutions were relatively immature and there was a great deal of turnover in the market I could appreciate the initiatives like Kuali. But let’s not kid ourselves – the real objective of this movement is to counter a perceived predatory commercial software industry. Again, when commercial solutions are deployed as written without significant customization, and standard business processes are adopted, the cost of these solutions (relative to the value delivered) is quite low, and certain much lower than the massive investment (and risk) in in-house developers to support a bespoke community source system. In this era of cost pressures in education and the need to refocus resources on teaching, learning, and research, I believe it’s bordering on irresponsible to continue to pursue open-source ERP. Many of the adopter’s total costs are staggering and have little to show for their efforts and expended resources. The second article was recently in the Chronicle of Higher Education and was entitled “’Big Data’ Is Bunk, Obama Campaign’s Tech Guru Tells University Leaders.” This one was so outrageous I almost don’t want to legitimize it by referencing it here. In the article the writer relays statements made by Harper Reed, President Obama’s former CTO for his 2012 re-election campaign, that big data solutions in education have no relevance and are akin to snake oil. He goes on to state that while he’s a fan of data-driven decision making in education, most of the necessary analysis can be accomplished in Excel spreadsheets. Yeah… right. This is exactly what ails education (higher education in particular). Dozens of shadow and siloed systems running on spreadsheets with limited-to-no enterprise wide initiatives to harness the data-rich environment that is a higher ed institution and transform the data into useable information. I’ll grant Mr. Reed that “Big Data” is overused and hackneyed, but imperatives like improving student success in higher education are classic big data problems that data-mining and predictive analytics can address. Further, higher ed need to be producing a massive amount more data scientists and analysts than are currently in the pipeline, to further this discipline and application of these tools to many many other problems across multiple industries.

  • How to build a great relationship with your colleagues

How will you get along with them? What if they don’t like you? Have you ever felt you’re „the new guy” and your colleagues have already their own way of talking one to each other, their own jokes? It’s a common feeling and can actually become stressful. I am Norbert, Middleware Presales Intern in Hungary and I’ve been working within Oracle for only 1 month. Joining such a big company has been a challenge from many perspectives. One of them was adapting with the environment and getting to know all my colleagues. You know it’s quite difficult to introduce yourself, to try to liaise with them and find some common topics, so I felt very lucky and comfortable when my manager introduced me to all of my colleagues. It was easier to accommodate and we basically we had a starting point for our discussions. We started to talk about what my position means, for how many years they’ve been within Oracle, other Oracle related topics, but also more personal stuff like what they do after work. Having this opportunity of talking with all of them helped me introduce myself in a proper way and actually I told them many things about myself. Networking wasn’t my best skill, but these first days were really helpful from a network point of view. What else can you do to get along with your colleagues? One second thing I consider as being really helpful in networking is asking work-related questions. For instance, when you don’t know how to do something or don’t understand it, asking one of your colleagues will also help you to make a connection with him and you could easily continue the discussion with some other topics which are more personal. It’s a very effective strategy and in a company like Oracle people are very willing to help you with your tasks and perform at a high level. If you see your colleagues going to lunch, you should join them. It will help you become part of their community, finding out what’s new in their lives, you’ll, step-by-step, take part in their conversations and be up to date with the hot topics they talk about. One other opportunity of becoming part of your colleagues’ community are the internal events. Subscribing to the local free time activities mailing list is very useful for finding out information about when they’re going out and have a drink or attending all sorts of events. For instance, this is how I’ve found out about a party within Oracle that most of the employees here attend. It’s a wonderful opportunity for chatting and make a stronger connection to some of them. How important is attending these events? Think about how much time you spend at work. You’d like to enjoy your work and the environment, so getting along with your colleagues is a nice thing to have. I recently attended a corporate party whose purpose was to facilitate the interaction and communication between employees. It was a real success and we had a lot of fun, especially because it was a costume party.  All the fancy dresses and funny clothes we wore made the atmosphere really enjoyable. It was easy to liaise with colleague with whom I had never interacted with before. There was a friendly spirit among us, chatting about personal stuff and about various pleasant things. Working in an international company is not an easy thing because you interact with many people and they have different styles, but all these opportunities of informal interaction are a good way to adapt to the new working environment.

  • Silverlight Cream Monday WP7 App Review # 1

    - by Dave Campbell
    I'm going to try something here... if it seems useful, I'll continue, if it doesn't, I'll stop... so give me feedback! There are *lots* of Apps in the WP7 Marketplace, and heaven help me, but the Marketplace sucks for finding stuff. I won't rehash what's already been said in the blogs, but I agree with one and all. I went out last Saturday to find 2 apps that I knew were released, and couldn't do so on my device. Even in the Zune app, it took quite a while to find them... ok, I'll back off a bit, because I just found out I can do 'Search' now if I know the name... I didn't think that was working before. So my thought is on Monday (like today), I will post a review of 5 apps/games I either use or have played with on my device. These are strictly my opinions, you understand, but hey... it's better than a poke in the eye with an iPhone! A few disclaimers:     Feel free to write me about your app and tell me about it. While it would be very cool to receive a whole bunch of xap files to review, at this point, for technical reasons, I'm unable to side-load my device. Since I plan on only doing this one day a week, and only 5, I may never get caught up, so if you send me some info, be patient. Re: games ... remember I'm old... I'm from the era of Colossal Cave and Zork. Duke-Nukem 2D and Captain Comic were awesome. I don't own an XBOX or any other game system, so take game reviews from my perspective -- who knows, it may be refreshing :) I won't pay for an app or game just to try it. If you expect me to test-drive your app, it's going to have to have a Free Trial. In this Issue:   Jingo! is the first app I bought, just to see what the experience was like. It's very much like a game we used to play in school in the Army in 1971 on paper we passed around. Sort of a cross between hangman and Mastermind, you try to figure out the hidden word in 5 tries. You get really good at 5-letter words after a while. I like this because you have to think, and you're not pressured by a clock Jingo! is by James Furdell and is $1.99 I reviewed René Schulte's Pictures Lab a while back, and have not changed my mind. This is an excellent app for playing with any photo on your device... one you've just taken, one you've synced from your PC, or one you've saved from email. I like this because you can get some cool effects for your photos, and it just works. Pictures Lab is by Schulte Software Development and is $1.99 Since I work as a consultant, and from home, I wanted something I could track my time with. I've test-driven all the contenders I could find so far on the phone, and so far I like ONTRACK! the best. If asked, I have some suggestions, but it's probably just the way I work or think. What I do like is I can tap a project to start/stop/restart a counter, and at the end of the day it shows me how much time I've been working. If there's a way to make an adjustment in case you forget to tap the counter, I don't know how to do it, and that's my biggest complaint. I like this because you can get a daily readout which you can also email as a spreadsheet. The daily results display is very good. ONTRACK! is by Qmino and is $2.99 Remember Item 4 above... I've been playing guitar for 48 years... obviously since before the invention of 'tuners', so I'm not as dependent upon these as some folks are. I've tried some in the past and have always felt I can do just as good by ear (I have perfect relative pitch). So, I gave this app by András Velvárt a dance just to see how it works, and it is surprisingly good. If you're used to one of the stage tuners this may take a little getting used to, but it does the job. The difference with this one is there is no real 'null' point inside which you can think your guitar is in tune. The soundwave stays visible on the device, and if it's moving to the right, your string is flat, if it's moving to the left, your string is sharp. Getting it exact might be tricky, but it is exact! If you need to rely on a tuner, this is a good choice in my opinion, exactly because of the sensitivity.. tune up with this and you're dead-on. Guitar Tuner is by Kinabalu Innovation Limited and is $0.99 Popper 2 is the WP7 version of a wildly popular game by Bill Reiss named Dr. Popper. You can get a trial, or you can now get a free lite version of the game. Popper 2 is a fast-paced bubble breaker game. I find it something fun to play when I just want to buzz out, but maybe the best review is that my daughter didn't want to give my phone back when I showed it to her, and always wants to grab my phone to play 'that game'. A fun distraction with great graphics and a great price Popper 2 is by Blue Rose Systems, LLC and is $1.29 Let me know what you think of the idea of doing reviews, or the layout/whatever, and Stay in the 'Light!   Twitter SilverlightNews | Twitter WynApse | WynApse.com | Tagged Posts | SilverlightCream Join me @ SilverlightCream | Phoenix Silverlight User Group Technorati Tags: Silverlight    Silverlight 3    Silverlight 4    Windows Phone MIX10

  • Day 1 - Finding Like Minds

    - by dapostolov
    So, is being a Game Developer any different from being an IT Developer? I picture a poorly lit environment where I get to purchase my own desk lamp; I'm thinking one of those huge lava lamps that pump out so much heat you could fry an egg on it. To my right: a "great wall" of empty coke cans dwarf me. Eating my last slice of pizza I look across my desk to see a fellow developer with a smug look on his face;  he's just coded his latest module for the game and it looks like he's in nirvana. My duty, of course, is to remind him to keep focused on the job at hand. So, picking up my trusty elastic and aerodynamically crafted paper bullet I begin a 10 minute war of welts and laughter which is promptly abrupted by our Project Manager demanding more details from our morning Scrum meeting. After providing about 5 minutes of geek speak and several words of comfort to make his eyes glaze over...it hits me, the idea for the module...beckoning my developer friend over, we quickly shoo the Project Manager away and begin our brainstorming frenzy ... now, where'd I put that full can of coke? OK. OK. This isn't probably the most ideal game developer environment, but it definitely sounds fun to me...and from what I gather is nothing like most game development companies. But I'm not doing this blog series to "go pro"; like I stated in my first post I want to make a 2D game from an idea my best friend and I drummed up long, long ago. I'm in this for the passion AND I want to see how easy it is for us .Net Developers to create a game. So where do I start? Where can I find like minded individuals? What technologies are there? What do I need to make a video game? The questions are endless....AND...since I already have an idea ... lets start with ... Technology (yes, I'm a geek, live with it...) Technology OK. Predominantly, games are still made in C++ or even C. I'm not sure how much assembly code is floating around lately, however, that is not my concern. I do know C / C++ from my past, enough to even get me by, but I'm mainly interested in a recent, not-so-new, technology called XNA. What is XNA? XNA allows us .Net Developers to make 2D / 3D games for windows, Xbox*, and Windows Mobile 7*. * = for a nominal fee *cough* The following link is your one stop shop to XNA game development: http://creators.xna.com/en-US/education/gettingstarted The above site hosts information such as: - getting started - a sample/instructional shooter game in 2D / 3D with code (if I'm taking too long for you in this blog series) - downloads - starter kits... http://creators.xna.com/en-US/education/starterkits/ And of course...forums. You can also subscribe and pay for their premium membership which gets you some pretty awesome tutorials, resources, downloads, and premium community support. Some general Wiki information about XNA: http://en.wikipedia.org/wiki/XNA_%28Microsoft%29 Community Support OK. Let's move on to industry and community support. Apart from XNA, there are some really cool sites out there, I just haven't found all of them yet. However, I found a really cool Game Development website called Gamastura. You can click on the following link to get you there: http://www.gamasutra.com/ The site is 100% dedicated to "The Art & Business of Making Games". Armed with blogs, twitter, jobs/resumes and most importantly industry news; one could subscribe to the feed and got lost in the wealth of information it provides. On a side note: I remember Gamasutra being around when my best friend and I wanted to make a video game...meaning, they've been around for a while now. I think the most beneficial aspect of this site is to understand the industry you want to get into. Otherwise, it's just a cool site to keep up to date with the industry in general. Another Community Support option is LinkedIn. Amongst the land of extremely bloated achievements and responsibilities lay 3 groups (that I have found) that deal with game development.: http://www.linkedin.com/groups?gid=59205 - Game Developers http://www.linkedin.com/groups?gid=824817 - DirectX Game Developer Network http://www.linkedin.com/groups?gid=756587 - DirectX Developers The Game Developers group in LinkedIn is by far the most active of the three and could possibly provide a wealth of support. What I've done thus far: - I lightly researched the XNA technology - I looked around for some community sites to assist me - I downloaded the XNA Game Studio 3.1 on my PC and installed it on my IDE - I even tried both tutorials! http://creators.xna.com/en-US/education/gettingstarted/bgintro/chapter1   Best Regards D.

  • BRE (Business Rules Engine) Data Services is out...!!!

    - by Vishal
    A few months ago we at Tellago had open sourced the BizTalk Data Services. We were meanwhile working on other artifacts which comes along with BizTalk Server like the “Business Rules Engine”.  We are happy to announce the first version of BRE Data Services. BRE Data Services is a same concept which we covered through BTS Data Services, providing a RESTFul OData – based API to interact with the Business Rules Engine via HTTP using ATOM Publishing Protocol or JSON as the encoding mechanism.   In the first version release, we mainly focused on the browsing, querying and searching BRE artifacts via a RESTFul interface. Also along with that we provide the functionality to execute Business Rules by inserting the Facts for policies via the IUpdatable implementation of WCF Data Services.   The BRE Data Services API provides a lightweight interface for managing Business Rules Engine artifacts such as Policies, Rules, Vocabularies, Conditions, Actions, Facts etc. The following are some examples which details some of the available features in the current version of the API.   Basic Querying: Querying BRE Policies http://localhost/BREDataServices/BREMananagementService.svc/Policies Querying BRE Rules http://localhost/BREDataServices/BREMananagementService.svc/Rules Querying BRE Vocabularies http://localhost/BREDataServices/BREMananagementService.svc/Vocabularies   Navigation: The BRE Data Services API also leverages WCF Data Services to enable navigation across related different BRE objects. Querying a specific Policy http://localhost/BREDataServices/BREMananagementService.svc/Policies(‘PolicyName’) Querying a specific Rule http://localhost/BREDataServices/BREMananagementService.svc/Rules(‘RuleName’) Querying all Rules under a Policy http://localhost/BREDataServices/BREMananagementService.svc/Policies('PolicyName')/Rules Querying all Facts under a Policy http://localhost/BREDataServices/BREMananagementService.svc/Policies('PolicyName')/Facts Querying all Actions for a specific Rule http://localhost/BREDataServices/BREMananagementService.svc/Rules('RuleName')/Actions Querying all Conditions for a specific Rule http://localhost/BREDataServices/BREMananagementService.svc/Rules('RuleName')/Actions Querying a specific Vocabulary: http://localhost/BREDataServices/BREMananagementService.svc/Vocabularies('VocabName')   Implementation: With the BRE Data Services, we also provide the functionality of executing a particular policy via HTTP. There are couple of ways you can do that though the API.   Ø First is though Service Operations feature of WCF Data Services in which you can execute the Facts by passing them in the URL itself. This is a very simple implementations of the executing the policies due to the limitations & restrictions (only primitive types of input parameters which can be passed) currently of the Service Operations of the WCF Data Services. Below is a code sample.                Below is a traced Request/Response message.                                 Ø Second is through the IUpdatable Interface of WCF Data Services. In this method, you can first query the rule which you want to execute and then inserts Facts for that particular Rules and finally when you perform the SaveChanges() call for the IUpdatable Interface API, it executes the policy with the facts which you inserted at runtime. Below is a sample of client side code. Due to the limitations of current version of WCF Data Services where there is no way you can return back the updates happening on the service side back to the client via the SaveChanges() method. Here we are executing the rule passing a serialized XML as Facts and there is no changes made to any data where we can query back to fetch the changes. This is overcome though the first way to executing the policies which is by executing it as a Service Operation call.     This actually generates a AtomPub message shown as below:   POST /Tellago.BRE.REST.ServiceHost/BREMananagementService.svc/$batch HTTP/1.1 User-Agent: Microsoft ADO.NET Data Services DataServiceVersion: 1.0;NetFx MaxDataServiceVersion: 2.0;NetFx Accept: application/atom+xml,application/xml Accept-Charset: UTF-8 Content-Type: multipart/mixed; boundary=batch_6b9a5ced-5ecb-4585-940a-9d5e704c28c7 Host: localhost:8080 Content-Length: 1481 Expect: 100-continue   --batch_6b9a5ced-5ecb-4585-940a-9d5e704c28c7 Content-Type: multipart/mixed; boundary=changeset_184a8c59-a714-4ba9-bb3d-889a88fe24bf   --changeset_184a8c59-a714-4ba9-bb3d-889a88fe24bf Content-Type: application/http Content-Transfer-Encoding: binary   MERGE http://localhost:8080/Tellago.BRE.REST.ServiceHost/BREMananagementService.svc/Facts('TestPolicy') HTTP/1.1 Content-ID: 4 Content-Type: application/atom+xml;type=entry Content-Length: 927   <?xml version="1.0" encoding="utf-8" standalone="yes"?> <entry xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" font-size: x-small"http://www.w3.org/2005/Atom">   <category scheme="http://schemas.microsoft.com/ado/2007/08/dataservices/scheme" term="Tellago.BRE.REST.Resources.Fact" />   <title />   <author>     <name />   </author>   <updated>2011-01-31T20:09:15.0023982Z</updated>   <id>http://localhost:8080/Tellago.BRE.REST.ServiceHost/BREMananagementService.svc/Facts('TestPolicy')</id>   <content type="application/xml">     <m:properties>       <d:FactInstance>&lt;ns0:LoanStatus xmlns:ns0="http://tellago.com"&gt;&lt;Age&gt;10&lt;/Age&gt;&lt;Status&gt;true&lt;/Status&gt;&lt;/ns0:LoanStatus&gt;</d:FactInstance>       <d:FactType>TestSchema</d:FactType>       <d:ID>TestPolicy</d:ID>     </m:properties>   </content> </entry> --changeset_184a8c59-a714-4ba9-bb3d-889a88fe24bf-- --batch_6b9a5ced-5ecb-4585-940a-9d5e704c28c7—     Installation: The installation of the BRE Data Services is pretty straight forward. ·         Create a new IIS website say BREDataServices. ·         Download the SourceCode from TellagoCodeplex and copy the content from Tellago.BRE.REST.ServiceHost to the physical location of the above created website.     ·         The appPool account running the website should have admin access to the BizTalkRuleEngineDb database. ·         TheRight click the BREManagementService.svc in the IIS ContentView for the website and wala..     Conclusion: The BRE Data Services API is an experiment intended to bring the capabilities of RESTful/OData based services to the Traditional BTS/BRE Solutions. The future releases will target on technologies like BAM, ESB Toolkit. This version has been tested with various version of BizTalk Server and we have uploaded the source code to our Tellago's DevLabs workspace at Codeplex. I hope you guys enjoy this release. Keep an eye on our new releases @ Tellago Codeplex. We are working on various other Biztalk Artifacts like BAM, ESB Toolkit.     Till than happy BizzRuling…!!!     Thanks,   Vishal Mody

  • Columnstore Case Study #2: Columnstore faster than SSAS Cube at DevCon Security

    - by aspiringgeek
    Preamble This is the second in a series of posts documenting big wins encountered using columnstore indexes in SQL Server 2012 & 2014.  Many of these can be found in my big deck along with details such as internals, best practices, caveats, etc.  The purpose of sharing the case studies in this context is to provide an easy-to-consume quick-reference alternative. See also Columnstore Case Study #1: MSIT SONAR Aggregations Why Columnstore? As stated previously, If we’re looking for a subset of columns from one or a few rows, given the right indexes, SQL Server can do a superlative job of providing an answer. If we’re asking a question which by design needs to hit lots of rows—DW, reporting, aggregations, grouping, scans, etc., SQL Server has never had a good mechanism—until columnstore. Columnstore indexes were introduced in SQL Server 2012. However, they're still largely unknown. Some adoption blockers existed; yet columnstore was nonetheless a game changer for many apps.  In SQL Server 2014, potential blockers have been largely removed & they're going to profoundly change the way we interact with our data.  The purpose of this series is to share the performance benefits of columnstore & documenting columnstore is a compelling reason to upgrade to SQL Server 2014. The Customer DevCon Security provides home & business security services & has been in business for 135 years. I met DevCon personnel while speaking to the Utah County SQL User Group on 20 February 2012. (Thanks to TJ Belt (b|@tjaybelt) & Ben Miller (b|@DBADuck) for the invitation which serendipitously coincided with the height of ski season.) The App: DevCon Security Reporting: Optimized & Ad Hoc Queries DevCon users interrogate a SQL Server 2012 Analysis Services cube via SSRS. In addition, the SQL Server 2012 relational back end is the target of ad hoc queries; this DW back end is refreshed nightly during a brief maintenance window via conventional table partition switching. SSRS, SSAS, & MDX Conventional relational structures were unable to provide adequate performance for user interaction for the SSRS reports. An SSAS solution was implemented requiring personnel to ramp up technically, including learning enough MDX to satisfy requirements. Ad Hoc Queries Even though the fact table is relatively small—only 22 million rows & 33GB—the table was a typical DW table in terms of its width: 137 columns, any of which could be the target of ad hoc interrogation. As is common in DW reporting scenarios such as this, it is often nearly to optimize for such queries using conventional indexing. DevCon DBAs & developers attended PASS 2012 & were introduced to the marvels of columnstore in a session presented by Klaus Aschenbrenner (b|@Aschenbrenner) The Details Classic vs. columnstore before-&-after metrics are impressive. Scenario Conventional Structures Columnstore ? SSRS via SSAS 10 - 12 seconds 1 second >10x Ad Hoc 5-7 minutes (300 - 420 seconds) 1 - 2 seconds >100x Here are two charts characterizing this data graphically.  The first is a linear representation of Report Duration (in seconds) for Conventional Structures vs. Columnstore Indexes.  As is so often the case when we chart such significant deltas, the linear scale doesn’t expose some the dramatically improved values corresponding to the columnstore metrics.  Just to make it fair here’s the same data represented logarithmically; yet even here the values corresponding to 1 –2 seconds aren’t visible.  The Wins Performance: Even prior to columnstore implementation, at 10 - 12 seconds canned report performance against the SSAS cube was tolerable. Yet the 1 second performance afterward is clearly better. As significant as that is, imagine the user experience re: ad hoc interrogation. The difference between several minutes vs. one or two seconds is a game changer, literally changing the way users interact with their data—no mental context switching, no wondering when the results will appear, no preoccupation with the spinning mind-numbing hurry-up-&-wait indicators.  As we’ve commonly found elsewhere, columnstore indexes here provided performance improvements of one, two, or more orders of magnitude. Simplified Infrastructure: Because in this case a nonclustered columnstore index on a conventional DW table was faster than an Analysis Services cube, the entire SSAS infrastructure was rendered superfluous & was retired. PASS Rocks: Once again, the value of attending PASS is proven out. The trip to Charlotte combined with eager & enquiring minds let directly to this success story. Find out more about the next PASS Summit here, hosted this year in Seattle on November 4 - 7, 2014. DevCon BI Team Lead Nathan Allan provided this unsolicited feedback: “What we found was pretty awesome. It has been a game changer for us in terms of the flexibility we can offer people that would like to get to the data in different ways.” Summary For DW, reports, & other BI workloads, columnstore often provides significant performance enhancements relative to conventional indexing.  I have documented here, the second in a series of reports on columnstore implementations, results from DevCon Security, a live customer production app for which performance increased by factors of from 10x to 100x for all report queries, including canned queries as well as reducing time for results for ad hoc queries from 5 - 7 minutes to 1 - 2 seconds. As a result of columnstore performance, the customer retired their SSAS infrastructure. I invite you to consider leveraging columnstore in your own environment. Let me know if you have any questions.

  • How to Identify Which Hardware Component is Failing in Your Computer

    - by Chris Hoffman
    Concluding that your computer has a hardware problem is just the first step. If you’re dealing with a hardware issue and not a software issue, the next step is determining what hardware problem you’re actually dealing with. If you purchased a laptop or pre-built desktop PC and it’s still under warranty, you don’t need to care about this. Have the manufacturer fix the PC for you — figuring it out is their problem. If you’ve built your own PC or you want to fix a computer that’s out of warranty, this is something you’ll need to do on your own. Blue Screen 101: Search for the Error Message This may seem like obvious advice, but searching for information about a blue screen’s error message can help immensely. Most blue screens of death you’ll encounter on modern versions of Windows will likely be caused by hardware failures. The blue screen of death often displays information about the driver that crashed or the type of error it encountered. For example, let’s say you encounter a blue screen that identified “NV4_disp.dll” as the driver that caused the blue screen. A quick Google search will reveal that this is the driver for NVIDIA graphics cards, so you now have somewhere to start. It’s possible that your graphics card is failing if you encounter such an error message. Check Hard Drive SMART Status Hard drives have a built in S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) feature. The idea is that the hard drive monitors itself and will notice if it starts to fail, providing you with some advance notice before the drive fails completely. This isn’t perfect, so your hard drive may fail even if SMART says everything is okay. If you see any sort of “SMART error” message, your hard drive is failing. You can use SMART analysis tools to view the SMART health status information your hard drives are reporting. Test Your RAM RAM failure can result in a variety of problems. If the computer writes data to RAM and the RAM returns different data because it’s malfunctioning, you may see application crashes, blue screens, and file system corruption. To test your memory and see if it’s working properly, use Windows’ built-in Memory Diagnostic tool. The Memory Diagnostic tool will write data to every sector of your RAM and read it back afterwards, ensuring that all your RAM is working properly. Check Heat Levels How hot is is inside your computer? Overheating can rsult in blue screens, crashes, and abrupt shut downs. Your computer may be overheating because you’re in a very hot location, it’s ventilated poorly, a fan has stopped inside your computer, or it’s full of dust. Your computer monitors its own internal temperatures and you can access this information. It’s generally available in your computer’s BIOS, but you can also view it with system information utilities such as SpeedFan or Speccy. Check your computer’s recommended temperature level and ensure it’s within the appropriate range. If your computer is overheating, you may see problems only when you’re doing something demanding, such as playing a game that stresses your CPU and graphics card. Be sure to keep an eye on how hot your computer gets when it performs these demanding tasks, not only when it’s idle. Stress Test Your CPU You can use a utility like Prime95 to stress test your CPU. Such a utility will fore your computer’s CPU to perform calculations without allowing it to rest, working it hard and generating heat. If your CPU is becoming too hot, you’ll start to see errors or system crashes. Overclockers use Prime95 to stress test their overclock settings — if Prime95 experiences errors, they throttle back on their overclocks to ensure the CPU runs cooler and more stable. It’s a good way to check if your CPU is stable under load. Stress Test Your Graphics Card Your graphics card can also be stress tested. For example, if your graphics driver crashes while playing games, the games themselves crash, or you see odd graphical corruption, you can run a graphics benchmark utility like 3DMark. The benchmark will stress your graphics card and, if it’s overheating or failing under load, you’ll see graphical problems, crashes, or blue screens while running the benchmark. If the benchmark seems to work fine but you have issues playing a certain game, it may just be a problem with that game. Swap it Out Not every hardware problem is easy to diagnose. If you have a bad motherboard or power supply, their problems may only manifest through occasional odd issues with other components. It’s hard to tell if these components are causing problems unless you replace them completely. Ultimately, the best way to determine whether a component is faulty is to swap it out. For example, if you think your graphics card may be causing your computer to blue screen, pull the graphics card out of your computer and swap in a new graphics card. If everything is working well, it’s likely that your previous graphics card was bad. This isn’t easy for people who don’t have boxes of components sitting around, but it’s the ideal way to troubleshoot. Troubleshooting is all about trial and error, and swapping components out allows you to pin down which component is actually causing the problem through a process of elimination. This isn’t a complete guide to everything that could likely go wrong and how to identify it — someone could write a full textbook on identifying failing components and still not cover everything. But the tips above should give you some places to start dealing with the more common problems. Image Credit: Justin Marty on Flickr

  • 3 Trends for SMBs around Social, Mobile, and Sensor

    - by Socially_Aware_Enterprise
    While I often am talking to big companies or discussing enterprise solutions. There are times when individuals ask me about Small or Medium sized business trends.  Interestingly,  the Enterprise Social, Mobile, and Sensor initiatives I regularly discuss are in fact related to even the Mom and Pop storefront. The eco-system of new service players in the Social-Mobile-Sensor space generally emerge developing partnerships with enterprises as they develop and bring economy to scale to their services for the larger market. And of course Oracle has an entire division dedicated for delivering products and support to help emerging companies compete without the need to open an industrial strength credit line.. So here are some trends that we are helping large enterprises to deploy today, but small and medium businesses should be able to take advantage of by the end of this year and starting into 2015. 1) The typical small business is generally "Localized". But the ability to be "Hyper-Localized" will come as location based services become ubiquitous. Many small businesses have one or several storefronts and theirs are typically within a single regional economic footprint. While the internet provides global reach, it will be the businesses that invest in social, mobile and local that will win in the end.  Of course I am a huge SoMoLo evangelist. The SMBs' content and targeting with platforms for Geo-Fencing, Geo-Conquesting and Path-Matching to HHI are all going to be accessible to them, if not for Mobile Apps, then via Mobile messaging in Social Networks that offer it.. Expect to be able to target FaceBook messaging not by city, but by store or mall… This makes being able to be "Hyper-Local" even more important. And with new proximity services coming online more than ever before, SMBs will operate and service customers with pinpoint accuracy right down to where they stand in an aisle. Geo-Conquesting will be huge for small players to place ads when customers pass through competitors regions. Car Dealers are doing this now.. But also of course iBeacons are now very cheap and getting easier to put in retail stores. The ability for sales to happen anywhere in the store via a mobile phone or tablet is huge, as it will give the small shop the flexibility to not have to "Guard the Register" as more or most transactions will be digital. Thus, M-Commerce and T-Commerce will change the job of cashier dramatically.. 2) Intra-Brand Advocacy, the idea now is that rather than just depend on your trusty social media manager and his team, you are going to push more and more individuals with expertise inside the organization to help manage, reach-out, and utilize social channels to manage the incoming questions and answers customers need. While for years CRM was the tool of the enterprise, today CRMs enable this now "Salesforce et al" capability to trickle throughout the company. This gives greater pressure to organize roles, but also flatten out the organization. Internal collaboration around topics and customer needs is going to be the key for SMBs to finally get serious about customer experiences. Their customers are online and in social networks. This includes not just B2C SMBs but also B2B companies as well. Don't believe me? To find the players just use hashtag #SocialSelling and you will see… 3) The Visual Networks will begin to move from Content Aggregators to Content Collaboration platforms, which means Pinterest, Instagram, Vine, & others will begin to move to add more features brands want, first marketing platforms, rather than unique brand partnerships as they do today, but this will open ways for SMBs to engage with clear brand messaging and metrics. Eventually providing more "Collaboration" between Brand and Consumer.. Don't think for a minute Facebook bought Oculus Rift so you could see your timeline in 3-D. The Social Networks I advise customers to invest in are ones that are audio and visual intrinsically. Players from SoundCloud to Pinterest are deploying ways for brands to harness their interactive visual or audio based social networks to sell ad units aka brand messaging. While the Social Media revolution is going on, the emphasis was on the social, today it more and more about the media in social, that enterprises soon small and medium businesses will be connected to.

  • Many Different Things Rolled into a Ball

    - by MOSSLover
    Yeah I know I don’t blog much anymore, because life has taken me places that don’t involve the interwebs unfortunately.  I am in the midst of planning two events, starting a non for profit, creating more sessions for various conferences, submitting to various conferences, working a 40 hour a week job, attempting to hang out with boyfriend/friends/family.  So you can see that list does not include this blog sadly that’s how it goes sometimes.  The bottom piece very important over any of the top pieces.  I haven’t seen St. Louis in a while and I get to go back.  I was gone from home for MVP Summit and Best Practices Conference, so the boyfriend and cat didn’t get to see me either for a bit.  Then you have to add in the whole toilet being broken fiasco this week.  Maintenance really thought it would be cool to turn off the ability to flush.  I mean who does that?  Then when we call the owner he comes by turns it on and we figure it was an accident, because well the next day no one came by to tell us there was a leak.  It was all kinds of strangeness and involved me running to other people’s toilets.  As Dan Usher would say, I was a sad panda for a few days.  So I guess I wanted to post a few thoughts here just because I can.  I do not like multiple content editor webparts embedded with html files in numerous pages doing the same thing.  I will tell you why I don’t like these particular webparts and the way they are being used.  First off if you have a bunch of pages with script includes it’s about time you should just dump them into the masterpage.  Why bother finding all 20 pages and changing those pages when you can just use a single masterpage that already exists? The other thing that is bothering me days is screen scraping.  Just don’t do it, because in 2010 you will find the UI is substantially slower.  I understand you are new and you have no idea what to do.  You are also using 2007 am I right?  So then you need to go to codeplex.com and type in a search for SPServices.  Download it, use it, love it and then have it’s babies (well maybe don’t go so far this is not the GRID in Tron). If you have a ton of constants in your code why did you not go in and create a webpart with a bunch of properties and/or link to a configuration list hidden in the browser?  This type of property and list could help you out in the long run.  The power users and administrators can now change the control without you having to compile it over and over again.  It’s good stuff.  Also, you can change the control without compiling it, especially in 2007 where you have to do a farm solution.  In 2010 you can do a sandbox solution I guess, but shouldn’t you make it as easy and supportable as possible for other users? In conclusion I’m an angry person when it comes to viewing something repeatedly and analyzing it in a system.  Now we will move on to the next topic…MVP Summit…So yeah I can’t really talk about particulars, but I can talk about my experience as a person.  Don’t build something up to be cooler than it is only to be dropped from your 10,000 foot perch.  My experience was great, but the content overall was something to be desired.  It’s ok I got to meet a lot of people I would not have met if I had not gone.  Some of it was surreal, such as product group members showing up and talking to us.  It was pretty neat.  Plus I never had the chance to get to that mythical MS Office in Redmond.  Prior to Summit it was like Rainbow Brites unicorn trying taunting me on television when I was a kid.  So I guess with all that said I give it a B.  It was awesome in some way, but lacking in other ways.  The cool part is that I got to go.  Would I have lived without going? Yes, but it was still cool. I could prattle on about other things and make this post massive, but I’m going to pass and give myself a piece of Sunday to play Rockband and do 800 other things.  I hope the two of you who read this blog are well.  I’ll catch you all at another juncture.  Have a good weekend and varying holidays in between.

  • Application Development: Python or Java (or PHP)

    - by luckysmack
    I'm looking to get into application development, such as Facebook or Android apps and games. I am doing this for fun and to learn. Once my skills are to par I would like to have some side income from the apps, but I'm not banking on living off that (just so you know where I'm coming from and know what my end goals are). Currently I know and am familiar with PHP and frameworks such as cakephp and yii. However, I have been wanting to learn another language to broaden my horizons and to become a better developer. So I have narrowed it down to 2 languages. Python, and Java (I can already hear people cringing at the difference in the languages I have chosen, but I have some reasons). Python: closer to PHP that Java. Cross platformability. Also great as a general scripting language and has many file system level benefits that PHP does not. Cleaner syntax, readability, blah blah and the list goed on. Python will work great for cross platform apps and can be run on many OS's and is supported by Facebook for app development. But there is no support on Android (for full fledged apps). Java: a much stronger typed language, very robust community and corporate backing. Knowing Java is also good for personal marketability for enterprises, if you're into that. The main benefit here is that Java can write apps natively for Android and the apps can be ported for web versions to play on Facebook. So while I have seen many developers prefer Java over the two, Java has this significant advantage, where I can market my apps in both markets and in the future build more potential income. But like I said it is for fun. While money isn't the goal, it would still be nice. PHP: I'm putting this here because I know it already, and I'm sure a case could be made for it. It obviously works great for Facebook but like Python does not do so well on android. While it's mostly the realm of 'application development' that appeals to me, I do find Android apps fairly interesting and something that has a ton of potential to. But then again Facebook has a ton more users and the apps can also potentially be more immersive (desktop vs. mobile). So this is why I'm kinda stuck on what route to choose. Python for Facebook and web apps, with likely faster development to production times, or Java which can be developed for any of the platforms to make apps. Side note: I'm not really trying to get into 3D development, mostly 2D. And I also want to make an app with real-time play (websockets, etc). Someone mentioned node, js to me for that but Python seems to be more globally versatile for my goals. So, to anyone that does Facebook or Android development in either language: what do you suggest? Any input is valuable and I do appreciate it. And sorry for being long winded. EDIT: as mentioned in one of the answers, my primary goal is gaming. Although I do have some plans for non gaming apps such as general web based and desktop based ones. But gaming is my main goal with the possibility of income. EDIT: Another consideration could be Jython. Writing Python code which is converted into Java bytecode. This would allow the ability to do Android apps using Python. I could be wrong though, I'm still looking into it. Update 1-26-11: I recently acquired a new job which required I learn .NET using C#. Im sure some of you are cringing already but I really like the whole system and how it all works together between desktop and web development. But, as I am still interested in Python very much, and after some research I have decided I will learn Python as well as the IronPython implementation for .NET. But (again: I know...) since .NET is mostly a Windows thing and not as cross-compatible as I like, I will be learning Mono which is a cross platform implementation of .NET where I can use what I learn at work using C# and what I want to learn, Python/IronPython. So while learning and writing C#/.NET @ work I will be learning Python - Mono - Iron Python for what I want to do personally. And the benefit of them all being very closely related will help me out a lot, I think. What do you guys think? I almost feel like that should be another question, but there's not much of a question. Either way, you guys gave very helpful input.

  • Can Google Employees See My Saved Google Chrome Passwords?

    - by Jason Fitzpatrick
    Storing your passwords in your web browser seems like a great time saver, but are the passwords secure and inaccessible to others (even employees of the browser company) when squirreled away? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader MMA is curious if Google employees have (or could have) access to the passwords he stores in Google Chrome: I understand that we are really tempted to save our passwords in Google Chrome. The likely benefit is two fold, You don’t need to (memorize and) input those long and cryptic passwords. These are available wherever you are once you log in to your Google account. The last point sparked my doubt. Since the password is available anywhere, the storage must in some central location, and this should be at Google. Now, my simple question is, can a Google employee see my passwords? Searching over the Internet revealed several articles/messages. Do you save passwords in Chrome? Maybe you should reconsider: Talks about your passwords being stolen by someone who has access to your computer account. Nothing mentioned about the central storage security and vulnerability. There is even a response from Chrome browser security tech lead about the first issue. Chrome’s insane password security strategy: Mostly along the same line. You can steal password from somebody if you have access to the computer account. How to Steal Passwords Saved in Google Chrome in 5 Simple Steps: Teaches you how to actually perform the act mentioned in the previous two when you have access to somebody else’s account. There are many more (including this one at this site), mostly along the same line, points, counter-points, huge debates. I refrain from mentioning them here, simply carry a search if you want to find them. Coming back to my original query, can a Google employee see my password? Since I can view the password using a simple button, definitely they can be unhashed (decrypted) even if encrypted. This is very different from the passwords saved in Unix-like OS’s where the saved password can never be seen in plain text. They use a one-way encryption algorithm to encrypt your passwords. This encrypted password is then stored in the passwd or shadow file. When you attempt to login, the password you type in is encrypted again and compared with the entry in the file that stores your passwords. If they match, it must be the same password, and you are allowed access. Thus, a superuser can change my password, can block my account, but he can never see my password. So are his concerns well founded or will a little insight dispel his worry? The Answer SuperUser contributor Zeel helps put his mind at ease: Short answer: No* Passwords stored on your local machine can be decrypted by Chrome, as long as your OS user account is logged in. And then you can view those in plain text. At first this seems horrible, but how did you think auto-fill worked? When that password field gets filled in, Chrome must insert the real password into the HTML form element – or else the page wouldn’t work right, and you could not submit the form. And if the connection to the website is not over HTTPS, the plain text is then sent over the internet. In other words, if chrome can’t get the plain text passwords, then they are totally useless. A one way hash is no good, because we need to use them. Now the passwords are in fact encrypted, the only way to get them back to plain text is to have the decryption key. That key is your Google password, or a secondary key you can set up. When you sign into Chrome and sync the Google servers will transmit the encrypted passwords, settings, bookmarks, auto-fill, etc, to your local machine. Here Chrome will decrypt the information and be able to use it. On Google’s end all that info is stored in its encrpyted state, and they do not have the key to decrypt it. Your account password is checked against a hash to log in to Google, and even if you let chrome remember it, that encrypted version is hidden in the same bundle as the other passwords, impossible to access. So an employee could probably grab a dump of the encrypted data, but it wouldn’t do them any good, since they would have no way to use it.* So no, Google employees can not** access your passwords, since they are encrypted on their servers. * However, do not forget that any system that can be accessed by an authorized user can be accessed by an unauthorized user. Some systems are easier to break than other, but none are fail-proof. . . That being said, I think I will trust Google and the millions they spend on security systems, over any other password storage solution. And heck, I’m a wimpy nerd, it would be easier to beat the passwords out of me than break Google’s encryption. ** I am also assuming that there isn’t a person who just happens to work for Google gaining access to your local machine. In that case you are screwed, but employment at Google isn’t actually a factor any more. Moral: Hit Win + L before leaving machine. While we agree with zeel that it’s a pretty safe bet (as long as your computer is not compromised) that your passwords are in fact safe while stored in Chrome, we prefer to encrypt all our logins and passwords in a LastPass vault. Have something to add to the explanation? Sound off in the the comments. Want to read more answers from other tech-savvy Stack Exchange users? Check out the full discussion thread here.

  • REST to Objects in C#

    RESTful interfaces for web services are all the rage for many Web 2.0 sites.  If you want to consume these in a very simple fashion, LINQ to XML can do the job pretty easily in C#.  If you go searching for help on this, youll find a lot of incomplete solutions and fairly large toolkits and frameworks (guess how I know this) this quick article is meant to be a no fluff just stuff approach to making this work. POCO Objects Lets assume you have a Model that you want to suck data into from a RESTful web service.  Ideally this is a Plain Old CLR Object, meaning it isnt infected with any persistence or serialization goop.  It might look something like this: public class Entry { public int Id; public int UserId; public DateTime Date; public float Hours; public string Notes; public bool Billable;   public override string ToString() { return String.Format("[{0}] User: {1} Date: {2} Hours: {3} Notes: {4} Billable {5}", Id, UserId, Date, Hours, Notes, Billable); } } Not that this isnt a completely trivial object.  Lets look at the API for the service.  RESTful HTTP Service In this case, its TickSpots API, with the following sample output: <?xml version="1.0" encoding="UTF-8"?> <entries type="array"> <entry> <id type="integer">24</id> <task_id type="integer">14</task_id> <user_id type="integer">3</user_id> <date type="date">2008-03-08</date> <hours type="float">1.00</hours> <notes>Had trouble with tribbles.</notes> <billable>true</billable> # Billable is an attribute inherited from the task <billed>true</billed> # Billed is an attribute to track whether the entry has been invoiced <created_at type="datetime">Tue, 07 Oct 2008 14:46:16 -0400</created_at> <updated_at type="datetime">Tue, 07 Oct 2008 14:46:16 -0400</updated_at> # The following attributes are derived and provided for informational purposes: <user_email>[email protected]</user_email> <task_name>Remove converter assembly</task_name> <sum_hours type="float">2.00</sum_hours> <budget type="float">10.00</budget> <project_name>Realign dilithium crystals</project_name> <client_name>Starfleet Command</client_name> </entry> </entries> Im assuming in this case that I dont necessarily care about all of the data fields the service is returning I just need some of them for my applications purposes.  Thus, you can see there are more elements in the <entry> XML than I have in my Entry class. Get The XML with C# The next step is to get the XML.  The following snippet does the heavy lifting once you pass it the appropriate URL: protected XElement GetResponse(string uri) { var request = WebRequest.Create(uri) as HttpWebRequest; request.UserAgent = ".NET Sample"; request.KeepAlive = false;   request.Timeout = 15 * 1000;   var response = request.GetResponse() as HttpWebResponse;   if (request.HaveResponse == true && response != null) { var reader = new StreamReader(response.GetResponseStream()); return XElement.Parse(reader.ReadToEnd()); } throw new Exception("Error fetching data."); } This is adapted from the Yahoo Developer article on Web Service REST calls.  Once you have the XML, the last step is to get the data back as your POCO. Use LINQ-To-XML to Deserialize POCOs from XML This is done via the following code: public IEnumerable<Entry> List(DateTime startDate, DateTime endDate) { string additionalParameters = String.Format("start_date={0}&end_date={1}", startDate.ToShortDateString(), endDate.ToShortDateString()); string uri = BuildUrl("entries", additionalParameters);   XElement elements = GetResponse(uri);   var entries = from e in elements.Elements() where e.Name.LocalName == "entry" select new Entry { Id = int.Parse(e.Element("id").Value), UserId = int.Parse(e.Element("user_id").Value), Date = DateTime.Parse(e.Element("date").Value), Hours = float.Parse(e.Element("hours").Value), Notes = e.Element("notes").Value, Billable = bool.Parse(e.Element("billable").Value) }; return entries; }   For completeness, heres the BuildUrl method for my TickSpot API wrapper: // Change these to your settings protected const string projectDomain = "DOMAIN.tickspot.com"; private const string authParams = "[email protected]&password=MyTickSpotPassword";   protected string BuildUrl(string apiMethod, string additionalParams) { if (projectDomain.Contains("DOMAIN")) { throw new ApplicationException("You must update your domain in ProjectRepository.cs."); } if (authParams.Contains("MyTickSpotPassword")) { throw new ApplicationException("You must update your email and password in ProjectRepository.cs."); } return string.Format("https://{0}/api/{1}?{2}&{3}", projectDomain, apiMethod, authParams, additionalParams); } Thats it!  Now go forth and consume XML and map it to classes you actually want to work with.  Have fun! Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • How to tell whether your programmers are under-performing?

    - by A Team Lead
    I am a team lead with 5+ developers. I have a developer (let's call him A) who is a good programmer, who writes good clean, easy to understand code. However he is somewhat difficult to manage, and sometimes I wonder whether he is really under-performing or not. Our company requires the developers to indicate the work progress in the bug tracker we use, not so much as to monitor the programmers but to let the stackholders know the progress. The thing is, A only updates a task progress when it is done ( maybe 3 weeks after it is first worked on) and this leaves everyone wondering what is going on in the middle of the development week. He wouldn't change his habit despite repeated probing. ( It's OK, developers hate paperwork, I do, too) Recent 2-3 months he on leave quite often due to various events-- either he is sick, or have to attend a lot of personal events etc. ( It's OK, bad things happen in a string. It's just a coincidence) We define sprints, or roadmaps for each month. And in the beginning of the sprint, we will discuss the amount of work each of the developers have to do in a sprint and the developers get to set the amount of time they need for each task. He usually won't be able to complete all of them. (It's OK, the developers are regularly missing deadlines not due to their fault). If only one or two of the above events happen, I won't feel that A is under-performing, but they all happen together. So I have the feeling that A is under-performing and maybe-- God forbid--- slacking off. This is just a feeling based on my years of experience as programmer. But I could be wrong. It is notoriously hard to measure the work of a programmer, given that not all two tasks are alike, and there lacks a standard objective to measure the commitment of a programmer to your company. It is downright impossible to tell whether the programmer is doing his job or slacking off. All you can do, is to trust them-- yeah, trusting and giving them autonomy is the best way for programmers to work, I know that, so don't start a lecture on why you need to trust your programmers, thank you every much-- but if they abuse your trust, can you know? My question is, how can you tell whether your programmers are under-performing? Surely there are experience team leads who know better than me on this? Outcome: I've a straight talk with him regarding my perception on his performance. He was indignant when I suggested that I had the feeling that he wasn't performing at his best level. He felt that this was a completely unfair feeling. I then replied that this was my feeling and I didn't know whether my feeling was right or not. He would have none of this and ended the discussion immediately. Before he left he said that he "would try to give more to the company" in a very cold tone. I was taken aback by his reaction. I am sure that I offended him in some ways. Not too sure whether that was the right thing to do for me to be so frank with him, though. Extra notes: I hate micromanaging. So all that we have for our software process is Sprint ( where tasks get prioritized and assigned, and at the end of the month, a review of the amount of work done). Developers would require to update the tasks as they go along everyday. There is no standup meeting, or anything of the sort. Mainly because we have the freedom to work from home and everyone cherishes this freedom. Although I am the one who sets the deadline, but the developers will provide the estimate for each tasks and I will decide-- based on the estimate-- the tasks that go into a particular sprint. If they can't finish the tasks at the end of the sprint, I will push them to the next. So theoretically one can just do only 1 or 2 tasks during the whole sprint and then push the remaining 99 tasks to the next sprint and still he will be fine as long as justifies this-- in the form of daily work progress updates

  • JustCode Provides Reflector Alternative

    - by Joe Mayo
    If you've been a loyal Reflector user, you've probably been exposed to the debacle surrounding RedGate's decision to no longer offer a free version.  Since then, the race has begun for a replacement with a provider that would stand by their promises to the community.  Mono has an ongoing free alternative, which has been available for a long time.  However, other vendors are stepping up to the plate, with their own offerings. If Not Reflector, Then What? One of these vendors is Telerik.  In their recent Q1 2011 release of JustCode, Telerik offers a decompilation utility rivaling what we've become accustomed to in Reflector.  Not only does Telerik offer a usable replacement, but they've (in my opinion), produced a product that integrates more naturally with visual Studio than any other product ever has.  Telerik's decompilation process is so easy that the accompanying demo in this post is blindingly short (except for the presence of verbose narrative). If you want to follow along with this demo, you'll need to have Telerik JustCode installed.  If you don't have JustCode yet, you can buy it or download a trial at the Telerik Web site . A Tall Tale; Prove It! With JustCode, you can view code in the .NET Framework or any other 3rd party library (that isn't well obfuscated).  This demo depends on LINQ to Twitter, which you can download from CodePlex.com and create a reference or install the package online as described in my previous post on NuGet.  Regardless of the method, you'll have a project with a reference to LINQ to Twitter.  Use a Console Project if you want to follow along with this demo. Note:  If you've created a Console project, remember to ensure that the Target Framework is set to .NET Framework 4.  The default is .NET Framework 4 Client Profile, which doesn't work with LINQ to Twitter.  You can check by double-clicking the Properties folder on the project and inspecting the Target Framework setting. Next, you'll need to add some code to your program that you want to inspect. Here, I add code to instantiate a TwitterContext, which is like a LINQ to SQL DataContext, but works with Twitter: var l2tCtx = new TwitterContext(); If you're following along add the code above to the Main method, which will look similar to this: using LinqToTwitter; namespace NuGetInstall { class Program { static void Main(string[] args) { var l2tCtx = new TwitterContext(); } } } The code above doesn't really do anything, but it does give something that I can show and demonstrate how JustCode decompilation works. Once the code is in place, click on TwitterContext and press the F12 (Go to Definition) key.  As expected, Visual Studio opens a metadata file with prototypes for the TwitterContext class.  Here's the result: Opening a metadata file is the normal way that Visual Studio works when navigating to the definition of a type where you don't have the code.  The scenario with TwitterContext happens because you don't have the source code to the file.  Visual Studio has always done this and you can experiment by selecting any .NET type, i.e. a string type, and observing that Visual Studio opens a metadata file for the .NET String type. The point I'm making here is that JustCode works the way Visual Studio works and you'll see how this can make your job easier. In the previous figure, you only saw prototypes associated with the code. i.e. Notice that the default constructor is empty.  Again, this is normal because Visual Studio doesn't have the ability to decompile code.  However, that's the purpose of this post; showing you how JustCode fills that gap. To decompile code, right click on TwitterContext in the metadata file and select JustCode Navigate -> Decompile from the context menu.  The shortcut keys are Ctrl+1.  After a brief pause, accompanied by a progress window, you'll see the metadata expand into full decompiled code. Notice below how the default constructor now has code as opposed to the empty member prototype in the original metadata: And Why is This So Different? Again, the big deal is that Telerik JustCode decompilation works in harmony with the way that Visual Studio works.  The navigate to functionality already exists and you can use that, along with a simple context menu option (or shortcut key) to transform prototypes into decompiled code. Telerik is filling the the Reflector/Red Gate gap by providing a supported alternative to decompiling code.  Many people, including myself, used Reflector to decompile code when we were stuck with buggy libraries or insufficient documentation.  Now we have an alternative that's officially supported by a company with an excellent track record for customer (developer) service, Telerik.  Not only that, JustCode has several other IDE productivity tools that make the deal even sweeter.

  • Career guidance/advice for Junior-level Software Engineer [closed]

    - by John Do
    I have quite a few questions on my mind, so please bare with me. Please don't feel obligated to answer all of them, any as you choose will do. I'd appreciate if you could share some insight on any of these. Before I begin, some context: I currently have almost two years of professional experience as a Software Engineer, mainly developing software in Java. At this point, I feel that I have reached the peak in my career growth at the current company I am at and therefore I am looking for a new job, ideally again, as a Software Engineer. I have been interviewing for the past few months casually but have not had luck with companies I have a passion for. So, in no particular order - 1) In general, what are your thoughts on having graduate degrees in CS / Software Engineering. How much does it influence a salary increase, and do you think it's beneficial when working on real-world problems? I get the sense that a graduate degree in the field is trivial unless you really have a passion for research. 2) In general, in professional practice, how often had you have to write your own data structures and "complex" algorithms from scratch? In my own work, I have found myself relying mainly on third-party frameworks and the Java standard library to implement solutions as per business requirements. What are your thoughts on this? 3) In terms of resume, I feel the most ambivalent here. I want to be able to "blemish" my resume to a certain extent so that it stands out from others', but at the same time I do not want to over-exagerate my abilities. How do you strike a balance here? For example: I say that I am proficient in Java with data structures and algorithms. This is obviously a subjective and relative statement. I've taken the classes in my undergrad, and I've applied it in my work experience. What I feel as "prociency" can be seen as junior-level to others. How do you know what to say? Most of the time, recruiters (with no technical background) will be looking for keywords that stand out. This leads me to my next question (4). 4) Just from interviewing for the past few months (and getting plenty of rejections), I've come to realize that I may not be as proficient in data structures and algorithms as I thought I was. Do you think it's a good idea to remove the "proficient in java/data structure and algorithms"? I feel that being too hoenst on the resume will impede me from scoring opportunities to even have an interview with top-notch companies. What are your thoughts? 5) What is the absolute "must-have" knowledge going into a technical interview? I've been practicing several algorithmic and data sturcture problems now, and I feel that my abilities to solve arbitrary problems efficiently has not gotten significantly better. Do you think these abilities are something innate - it's either you have in you, or you don't? How can you teach yourself to learn, if you will? 6) How easy is it to go from industry/function to the next? I work mainly with backend technologies and I'm now interested in working with the frontend, i.e javascript,jquery,php or even mobile development. In your own experience, how did you not get pidgeon holed in your career? I feel that the choices you make now ultimately decide your future. As cliche as it sounds, I think it may be true. Here's what I mean: you've worked mainly as a backend engineer, people are interested in you doing the same thing since you've already accumulated experience in that function. How do get experience in a new function if people won't accept you because you don't already have it? It's a catch 22, you see... Are side projects the only real way to help you move from one function to another that you're truly interested in? For example: I could start writing my own mobile applications, even though I've worked mainly on the backend. Thanks so much for the long read. As a relatively new engineer to the real world, I am very humble and would like those who are experienced to shed some light. Thank you so much.

  • Visual Studio 2010 Productivity Tips and Tricks&ndash;Part 1: Extensions

    - by ToStringTheory
    I don’t know about you, but when it comes to development, I prefer my environment to be as free of clutter as possible.  It may surprise you to know that I have tried ReSharper, and did not like it, for the reason that I stated above.  In my opinion, it had too much clutter.  Don’t get me wrong, there were a couple of features that I did like about it (inversion of if blocks, code feedback), but for the most part, I actually felt that it was slowing me down. Introduction Another large factor besides intrusiveness/speed in my choice to dislike ReSharper would probably be that I have become comfortable with my current setup and extensions.  I believe I have a good collection, and am quite happy with what I can accomplish in a short amount of time.  I figured that I would share some of my tips/findings regarding Visual Studio productivity here, and see what you had to say. The first section of things that I would like to cover, are Visual Studio Extensions.  In case you have been living under a rock for the past several years, Extensions are available under the Tools menu in Visual Studio: The extension manager enables integrated access to the Microsoft Visual Studio Gallery online with access to a few thousand different extensions.  I have tried many extensions, but for reasons of lack reliability, usability, or features, have uninstalled almost all of them.  However, I have come across several that I find I can not do without anymore: NuGet Package Manager (Microsoft) Perspectives (Adam Driscoll) Productivity Power Tools (Microsoft) Web Essentials (Mads Kristensen) Extensions NuGet Package Manager To be honest, I debated on whether or not to put this in here.  Most people seem to have it, however, there was a time when I didn’t, and was always confused when blogs/posts would say to right click and “Add Package Reference…” which with one of the latest updates is now “Manage NuGet Packages”.  So, if you haven’t downloaded the NuGet Package Manager yet, or don’t know what it is, I would highly suggest downloading it now! Features Simply put, the NuGet Package Manager gives you a GUI and command line to access different libraries that have been uploaded to NuGet. Some of its features include: Ability to search NuGet for packages via the GUI, with information in the detail bar on the right. Quick access to see what packages are in a solution, and what packages have updates available, with easy 1-click updating. If you download a package that requires references to work on other NuGet packages, they will be downloaded and referenced automatically. Productivity Tip If you use any type of source control in Visual Studio as well as using NuGet packages, be sure to right-click on the solution and click "Enable NuGet Package Restore". What this does is add a NuGet package to the solution so that it will be checked in along side your solution, as well as automatically grab packages from NuGet on build if needed. This is an extremely simple system to use to manage your package references, instead of having to manually go into TFS and add the Packages folder. Perspectives I can't stand developing with just one monitor. Especially if it comes to debugging. The great thing about Visual Studio 2010, is that all of the panels and windows are floatable, and can dock to other screens. The only bad thing is, I don't use the same toolset with everything that I am doing. By this, I mean that I don't use all of the same windows for debugging a web application, as I do for coding a WPF application. Only thing is, Visual Studio doesn't save the screen positions for all of the undocked windows. So, I got curious one day and decided to check and see if there was an extension to help out. This is where I found Perspectives. Features Perspectives gives you the ability to configure window positions across any or your monitors, and then to save the positions in a profile. Perspectives offers a Panel to manage different presets/favorites, and a toolbar to add to the toolbars at the top of Visual Studio. Ability to 'Favorite' a profile to add it to the perspectives toolbar. Productivity Tip Take the time to setup profiles for each of your scenarios - debugging web/winforms/xaml, coding, maintenance, etc. Try to remember to use the profiles for a few days, and at the end of a week, you may find that your productivity was never better. Productivity Power Tools Ah, the Productivity Power Tools... Quite possibly one of my most used extensions, if not my most used. The tool pack gives you a variety of enhancements ranging from key shortcuts, interface tweaks, and completely new features to Visual Studio 2010. Features I don't want to bore you with all of the features here, so here are my favorite: Quick Find - Unobtrusive search box in upper-right corner of the code window. Great for searching in general, especially in a file. Solution Navigator - The 'Solution Explorer' on steroids. Easy to search for files, see defined members/properties/methods in files, and my favorite feature is the 'set as root' option. Updated 'Add Reference...' Dialog - This is probably my favorite enhancement period... The 'Add Reference...' dialog redone in a manner that resembles the Extension/Package managers. I especially love the ability to search through all of the references. "Ctrl - Click" for Definition - I am still getting used to this as I usually try to use my keyboard for everything, but I love the ability to hold Ctrl and turn property/methods/variables into hyperlinks, that you click on to see their definitions. Great for travelling down a rabbit hole in an application to research problems. While there are other commands/utilities, I find these to be the ones that I lean on the most for the usefulness. Web Essentials If you have do any type of web development in ASP .Net, ASP .Net MVC, even HTML, I highly suggest grabbing the Web Essentials right NOW! This extension alone is great for productivity in web development, and greatly decreases my development time on new features. Features Some of its best features include: CSS Previews - I say 'previews' because of the multiple kinds of previews in CSS that you get font-family, color, background/background-image previews. This is great for just tweaking UI slightly in different ways and seeing how they look in the CSS window at a glance. Live Preview - One word - awesome! This goes well with my multi-monitor setup. I put the site on one monitor in a Live Preview panel, and then as I make changes to CSS/cshtml/aspx/html, the preview window will update with each save/build automatically. For CSS, you can even turn on live-update, so as you are tweaking CSS, the style changes in real time. Great for tweaking colors or font-sizes. Outlining - Small, but I like to be able to collapse regions/declarations that are in the way of new work, or are just distracting. Commenting Shortcuts - I don't know why it wasn't included by default, but it is nice to have the key shortcuts for commenting working in the CSS editor as well. Productivity Tip When working on a site, hit CTRL-ALT-ENTER to launch the Live Preview window. Dock it to another monitor. When you make changes to the document/css, just save and glance at the other monitor. No need to alt tab, then alt tab before continuing editing. Conclusion These extensions are only the most useful and least intrusive - ones that I use every day. The great thing about Visual Studio 2010 is the extensibility options that it gives developers to utilize. Have an extension that you use that isn't intrusive, but isn't listed here? Please, feel free to comment. I love trying new things, and am always looking for new additions to my toolset of the most useful. Finally, please keep an eye out for Part 2 on key shortcuts in Visual Studio. Also, if you are visiting my site (http://tostringtheory.com || http://geekswithblogs.net/tostringtheory) from an actual browser and not a feed, please let me know what you think of the new styling!
