  • Custom animation problem in Powerpoint 2003

    - by Tom Gullen
    I have an animation of a grid that scrolls to the left. It's a Gantt chart, and it works fine. I then have several elements I want to drop on the grid, I give them all the same movement animation and this works fine, everything scrolls at the same speed and time. However I want to add entrance animations for the elements on the grid, I can have it so that when all the entrance animations are complete then it starts scrolling, but I want it to enter whilst it is scrolling. How do you have an entrance animation for an element and keep it's position updated? The entrance animation and movement animation don't seem to work together as expected when run simultaneously. cheers!

  • Hidden characters inserted after pipe (|) followed by a space

    - by nifty
    Very often, on my Mac, when I use the pipe (|) character followed by a space character, an invincible character will be inserted in between. This is especially annoying when using the terminal, as it makes commands invalid. If I type the following in iterm2, I often get the following: ls | cat zsh: command not found:  cat If I hit the up-arrow-key to get my previous command, and then remove and reinsert the space between | and cat, the command will work. When I copy paste the working and non working commands into a file, like this: non-working: ls | cat working: ls | cat and open it in Hex Fiend it shows the following: non-working: ls |¬†cat working: ls | cat I've also experienced the same kind of issue in SublimeText2 using the square brackets ([]) followed by a space. So I don't believe its an issue with iTerm2.

  • How to invert scroll wheel in certain applications using AutoHotkey?

    - by endolith
    I want to be able to modify the scrolling/middle click behavior for individual apps on Windows 7, so that the scroll to zoom direction is always consistent across apps. This script makes the middle button act as a hand tool in Adobe Acrobat, for instance: ; Hand tool with middle button in Adobe Reader #IfWinActive ahk_class AdobeAcrobat Mbutton:: #IfWinActive ahk_class AcrobatSDIWindow Mbutton:: Send {Space down}{LButton down} ; Hold down the left mouse button. KeyWait Mbutton ; Wait for the user to release the middle button. Send {LButton up}{Space up} ; Release the left mouse button. return #IfWinActive (It would be great if this could be adapted to allow "throwing" the document, too, like in Android or iPhone interfaces, but I don't know if it's possible to control scrolling that precisely) How do I invert the scroll wheel--zoom direction?

  • How can I force my browser to search Google in English?

    - by Tom Wijsman
    I'm too bored of seeing sites like Google and such show up in my native language, I would rather like them to be in English. Yet, I have to explicitly change the URL to .com and en and that kind of parameters in order for them to show up in English. Can I somehow force this? So, how is Google configured? However, it is set to English on the site itself so it has to be my browser: Then, how does my browser land up on non-english pages, like Google? It usually shows up in non-English when I'm performing a search, which uses: {google:baseURL}search?{google:RLZ}{google:acceptedSuggestion}{google:originalQueryForSuggestion}{google:searchFieldtrialParameter}{google:instantFieldTrialGroupParameter}sourceid=chrome&ie={inputEncoding}&q=%s When performing a search, it fills these variables in with non-english values. How can I tell my browser to fill these in with the English values? My Google Chrome options give preference to English:

  • Bash - Test for multiple users

    - by Mike Purcell
    I am trying to test if current user one of two allowed users to start a process, but I can't seem to get the multi-condition to work correctly: test ($(whoami) != 'mpurcell' || $(whoami) != 'root')) && (echo "Cannot start script as non-ccast user..."; exit 1) Is there a way to test multiple users without have to enter two lines, like this: test $(whoami) != 'mpurcell' && (echo "Cannot start script as non-ccast user..."; exit 1) test $(whoami) != 'root' && (echo "Cannot start script as non-ccast user..."; exit 1)

  • How can I automatically convert all source code files in a folder (recursively) to a single PDF with syntax highlighting?

    - by Bentley4
    I would like to convert source code of a few projects to one printable file to save on a usb and print out easily later. How can I do that? Edit First off I want to clarify that I only want to print the non-hidden files and directories(so no contents of .git e.g.). To get a list of all non-hidden files in non-hidden directories in the current directory you can run the find . -type f ! -regex ".*/\..*" ! -name ".*" command as seen as the answer in this thread. As suggested in that same thread I tried making a pdf file of the files by using the command find . -type f ! -regex ".*/\..*" ! -name ".*" ! -empty -print0 | xargs -0 a2ps -1 --delegate no -P pdf but unfortunately the resulting pdf file is a complete mess.

  • Editor that supports renaming tabs for untitled docs?

    - by OverTheRainbow
    I sometimes need to copy/paste text into two windows and compare the contents for a quick hack, ie. without having to save both documents to disk, and display the two docs side-by-side vertically so I can scroll them independantly (WinMerge doesn't seem to support independent scrolling.) Since the documents only live in RAM, text editors will display a non-descript tab/filename like "Untitled1" or "New file 1": http://img171.imageshack.us/img171/1153/sidebysideunleddocs.jpg Does someone know of a Windows editor that supports... renaming tabs with more descriptive names even with documents that haven't been saved to disk, side-by-side, vertical tiling, and independant scrolling? Thank you.

  • How do I change the canvas size of a PNG with ImageMagick (GraphicsMagick)? (How to pad with transparency?)

    - by Pistos
    Alternatively: How do I take a non-square PNG and "fill out" the "rest" of the image with transparency so that the resulting square image has the original image centered in the square? ULTIMATELY, what I want is to take any image of any GM-supported format of any size, and create a scaled-down PNG (say, 40 pixels maximum for either dimension), with aspect ratio maintained, transparency-padded for non-square original images, AND with an already-prepared 40x40 PNG transparency mask applied. I already know how to scale down and keep aspect ratio; I already have the command for applying my composite. My only missing piece is square-alizing non-square images (padding with transparency). Single command preferred; multi-command chain acceptable. (edit) Extra info: Here's the composite command I'm using: gm composite -compose copyopacity mask.png source-and-target.png source-and-target.png where mask.png has white pixels for what I want to keep of source-and-target.png and transparent pixels for what I want to remove (and become transparent) of source-and-target.png.

  • Is it possible to view Facebook news feeds page by page rather than loading it all as I scroll?

    - by oscilatingcretin
    If you want to scroll through your Facebook news feed (be it on the main feed, your personal feed, or in groups) to older parts, you have to scroll to the bottom, wait for the ajax load of the next part of the feed, and repeat. The problem with this is that, if you're scrolling down very far, the HTML document just gets bigger and bigger until your browser starts to die due to the overload of resources brought on by added HTML, text, and even images. This pretty much sets a limit to how far back you can scroll. Clicking on months and years on your personal feed has the same effect of cumulatively adding feed segments to the HTML document. I notice that this month/year feature is not available on the main feed and for groups. If there were a way to literally page through the feed so that only a single page's worth of feed data is loaded at a time, that would make scrolling through it much more doable.

  • How is the PHP extensions/modules file structure logic based?

    - by dotpointer
    I'm trying to configure/build PHP 5.3.10 on Linux/Slackware 12 but the extensions appear in the wrong directory when I run make install. In the php.ini file is the extension dir defined: /usr/lib/php/extensions Problem is that when I run "make install" the newly built extensions are copied to a subfolder in extensions directory: /usr/lib/php/extensions/no-debug-non-zts-20090626 What am I supposed to do with this... copy the files down from the no-debug-non-zts-20090626 directory into the extensions directory, create symlinks from extensions to the modules in the no-debug-non-zts-20090626 directory (which will take a lot of time) or what? (I know I can do any of them, but I want to know the correct way...)

  • ElanTech touchpad both keys simultaneously don't work

    - by Wojciech
    I have a huge problem with ElanTech touchpad. Without the ElanTech driver both the keys can be used at the same time(R+L). This is usefull in games like Mafia2 (can't play without it). When I install their driver I get the gestures, scrolling etc. but I can't use both keys at the same time. It is a common problem. Acer Aspire v3-571G Windows 7 x64 This didn't work at all: Synaptics 15.3.41.5 Is there any universal driver which will give me at least scrolling and simultaneous keys usage?

  • MVC2 and MVC Futures causing RedirectToAction issues

    - by Darragh
    I've been trying to get the strongly typed version of RedirectToAction from the MVC Futures project to work, but I've been getting no where. Below are the steps I've followed, and the errors I've encountered. Any help is much appreciated. I created a new MVC2 app and changed the About action on the HomeController to redirect to the Index page. Return RedirectToAction("Index") However, I wanted to use the strongly typed extensions, so I downloaded the MVC Futures from CodePlex and added a reference to Microsoft.Web.Mvc to my project. I addded the following "import" statement to the top of HomeContoller.vb Imports Microsoft.Web.Mvc I commented out the above RedirectToAction and added the following line: Return RedirectToAction(Of HomeController)(Function(c) c.Index()) So far, so good. However, I noticed if I uncomment out the first (non Generic) RedirectToAction, it was now causing the following compile error: Error 1 Overload resolution failed because no accessible 'RedirectToAction' can be called with these arguments: Extension method 'Public Function RedirectToAction(Of TController)(action As System.Linq.Expressions.Expression(Of System.Action(Of TController))) As System.Web.Mvc.RedirectToRouteResult' defined in 'Microsoft.Web.Mvc.ControllerExtensions': Data type(s) of the type parameter(s) cannot be inferred from these arguments. Specifying the data type(s) explicitly might correct this error. Extension method 'Public Function RedirectToAction(action As System.Linq.Expressions.Expression(Of System.Action(Of HomeController))) As System.Web.Mvc.RedirectToRouteResult' defined in 'Microsoft.Web.Mvc.ControllerExtensions': Value of type 'String' cannot be converted to 'System.Linq.Expressions.Expression(Of System.Action(Of mvc2test1.HomeController))'. Even though intelli-sense was showing 8 overloads (the original 6 non-generic overloads, plus the 2 new generic overloads from the Futures assembly), it seems when trying to complie the code, the compiler would only 'find' the 2 non-gneneric extension methods from the Futures assessmbly. I thought this might be an issue that I was using conflicting versions of the MVC2 assembly, and the futures assembly, so I added MvcDiaganotics.aspx from the Futures download to my project and everytyhing looked correct: ASP.NET MVC Assembly Information (System.Web.Mvc.dll) Assembly version: ASP.NET MVC 2 RTM (2.0.50217.0) Full name: System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 Code base: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Web.Mvc/2.0.0.0__31bf3856ad364e35/System.Web.Mvc.dll Deployment: GAC-deployed ASP.NET MVC Futures Assembly Information (Microsoft.Web.Mvc.dll) Assembly version: ASP.NET MVC 2 RTM Futures (2.0.50217.0) Full name: Microsoft.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null Code base: file:///xxxx/bin/Microsoft.Web.Mvc.DLL Deployment: bin-deployed This is driving me crazy! Becuase I thought this might be some VB issue, I created a new MVC2 project using C# and tried the same as above. I added the following "using" statement to the top of HomeController.cs using Microsoft.Web.Mvc; This time, in the About action method, I could only manage to call the non-generic RedirectToAction by typing the full commmand as follows: return Microsoft.Web.Mvc.ControllerExtensions.RedirectToAction<HomeController>(this, c => c.Index()); Even though I had a "using" statement at the top of the class, if I tried to call the non-generic RedirectToAction as follows: return RedirectToAction<HomeController>(c => c.Index()); I would get the following compile error: Error 1 The non-generic method 'System.Web.Mvc.Controller.RedirectToAction(string)' cannot be used with type arguments What gives? It's not like I'm trying to do anything out of the ordinary. It's a simple vanilla MVC2 project with only a reference to the Futures assembly. I'm hoping that I've missed out something obvious, but I've been scratching my head for too long, so I figured I'd seek some assisstance. If anyone's managed to get this simple scenario working (in VB and/or C#) could they please let me know what, if anything, they did differently? Thanks!

  • C++/msvc6 application crashes due to heap corruption, any hints?

    - by David Alfonso
    Hello all, let me say first that I'm writing this question after months of trying to find out the root of a crash happening in our application. I'll try to detail as much as possible what I've already found out about it. About the application It runs on Windows XP Professional SP2. It's built with Microsoft Visual C++ 6.0 with Service Pack 6. It's MFC based. It uses several external dlls (e.g. Xerces, ZLib or ACE). It has high performance requirements. It does a lot of network and hard disk I/O, but it's also cpu intensive. It has an exception handling mechanism which generates a minidump when an unhandled exception occurs. Facts about the crash It only happens on multiprocessor/multicore machines and under heavy loads of work. It happens at random (neither we nor our client have found a pattern yet). We cannot reproduce the crash on our testing lab. It only happens on some production systems (but always in multicore machines) It always ends up crashing at the same point, although the complete stack is not always the same. Let me add the stack of the crashing thread (obtained using WinDbg, sorry we don't have symbols) ChildEBP RetAddr Args to Child WARNING: Stack unwind information not available. Following frames may be wrong. 030af6c8 7c9206eb 77bfc3c9 01a80000 00224bc3 MyApplication+0x2a85b9 030af960 7c91e9c0 7c92901b 00000ab4 00000000 ntdll!RtlAllocateHeap+0xeac (FPO: [Non-Fpo]) 030af98c 7c9205c8 00000001 00000000 00000000 ntdll!ZwWaitForSingleObject+0xc (FPO: [3,0,0]) 030af9c0 7c920551 01a80898 7c92056d 313adfb0 ntdll!RtlpFreeToHeapLookaside+0x22 (FPO: [2,0,4]) 030afa8c 4ba3ae96 000307da 00130005 00040012 ntdll!RtlFreeHeap+0x1e9 (FPO: [Non-Fpo]) 030afacc 77bfc2e3 0214e384 3087c8d8 02151030 0x4ba3ae96 030afb00 7c91e306 7c80bfc1 00000948 00000001 msvcrt!free+0xc8 (FPO: [Non-Fpo]) 030afb20 0042965b 030afcc0 0214d780 02151218 ntdll!ZwReleaseSemaphore+0xc (FPO: [3,0,0]) 030afb7c 7c9206eb 02e6c471 02ea0000 00000008 MyApplication+0x2965b 030afe60 7c9205c8 02151248 030aff38 7c920551 ntdll!RtlAllocateHeap+0xeac (FPO: [Non-Fpo]) 030afe74 7c92056d 0210bfb8 02151250 02151250 ntdll!RtlpFreeToHeapLookaside+0x22 (FPO: [2,0,4]) 030aff38 77bfc2de 01a80000 00000000 77bfc2e3 ntdll!RtlFreeHeap+0x647 (FPO: [Non-Fpo]) 7c92056d c5ffffff ce7c94be ff7c94be 00ffffff msvcrt!free+0xc3 (FPO: [Non-Fpo]) 7c920575 ff7c94be 00ffffff 12000000 907c94be 0xc5ffffff 7c920579 00ffffff 12000000 907c94be 90909090 0xff7c94be *** WARNING: Unable to verify checksum for xerces-c_2_7.dll *** ERROR: Symbol file could not be found.

What I have tried so far Reviewing all the code related to the point where the crash ends happening. Trying to enable pageheap on our testing lab though nothing useful has been found by now. We have substituted the std::list for a C array and then it crashes in other part of the code (although it is related code, it's not in the code where the old list resided). Coincidentally, now it crashes in another erase, though this time of a std::multiset. Let me copy the stack contained in the dump: ntdll.dll!_RtlpCoalesceFreeBlocks@16() + 0x124e bytes ntdll.dll!_RtlFreeHeap@12() + 0x91f bytes msvcrt.dll!_free() + 0xc3 bytes MyApplication.exe!006a4fda() [Frames below may be incorrect and/or missing, no symbols loaded for MyApplication.exe] MyApplication.exe!0069f305() ntdll.dll!_NtFreeVirtualMemory@16() + 0xc bytes ntdll.dll!_RtlpSecMemFreeVirtualMemory@16() + 0x1b bytes ntdll.dll!_ZwWaitForSingleObject@12() + 0xc bytes ntdll.dll!_RtlpFreeToHeapLookaside@8() + 0x26 bytes ntdll.dll!_RtlFreeHeap@12() + 0x114 bytes msvcrt.dll!_free() + 0xc3 bytes c5ffffff() Possible solutions (that I'm aware of) which cannot be applied "Migrate the application to a newer compiler": We are working on this but It's not a solution at the moment. "Enable pageheap (normal or full)": We can't enable pageheap on production machines as this affects performance heavily. I think that's all I remember now, if I have forgotten something I'll add it asap. If you can give me some hint or propose some possible solution, don't hesitate to answer! Thank you in advance for your time and advice.

  • Thread Synchronization and Synchronization Primitives

    When considering synchronization in an application, the decision truly depends on what the application and its worker threads are going to do. I would use synchronization if two or more threads could possibly manipulate the same instance of an object at the same time. An example of this in C# can be demonstrated through the use of storing data in a static object. A static object is initialized once per application and the data within the object can be accessed by all threads. I would use the synchronization primitives to prevent any data from being manipulated by multiple threads simultaneously. This would reduce any data corruption from occurring within the object. On the other hand if all the threads used non static objects and were independent of the other tasks there would be no need to use synchronization. Synchronization Primitives in C#: Basic Blocking Locking Signaling Non-Blocking Synchronization Constructs The Basic Blocking methods include Sleep, Join, and Task.Wait.  These methods force threads to wait until other threads have completed. In addition, these methods can also force a thread to wait a set amount of time before continuing to work.   The Locking primitive prevents a thread from entering a critical section of code while another thread is in the same critical section.  If another thread attempts to enter a locked code, it will wait, until the code block is released. The Signaling primitive allows a thread to temporarily pause work until receiving a notification from another thread that it is ok to continue working. The Signaling primitive removes the need for polling.The Non-Blocking Synchronization Constructs protect access to a common field by calling upon processor primitives.

  • Do’s and Don’ts Building SharePoint Applications

    - by Bil Simser
    SharePoint is a great platform for building quick LOB applications. Simple things from employee time trackers to server and software inventory to full blown Help Desks can be crafted up using SharePoint from just customizing Lists. No programming necessary. However there are a few tricks I’ve painfully learned over the years that you can use for your own solutions. DO What’s In A Name? When you create a new list, column, or view you’ll commonly name it something like “Expense Reports”. However this has the ugly effect of creating a url to the list as “Expense%20Reports”. Or worse, an internal field name of “Expense_x0x0020_Reports” which is not only cryptic but hard to remember when you’re trying to find the column by internal name. While “Expense Reports 2011” is user friendly, “ExpenseReports2011” is not (unless you’re a programmer). So that’s not the solution. Well, not entirely. Instead when you create your column or list or view use the scrunched up name (I can’t think of the technical term for it right now) of “ExpenseReports2011”, “WomenAtTheOfficeThatAreMen” or “KoalaMeatIsGoodWhenBroiled”. After you’ve created it, go back and change the name to the more friendly “Silly Expense Reports That Nobody Reads”. The original internal name will be the url and code friendly one without spaces while the one used on data entry forms and view headers will be the human version. Smart Columns When building a view include columns that make sense. By default when you add a column the “Add to default view” is checked. Resist the urge to be lazy and leave it checked. Uncheck that puppy and decide consciously what columns should be included in the view. Pick columns that make sense to what the user is trying to do. This means you have to talk to the user. Yes, I know. That can be trying at times and even painful. Go ahead, talk to them. You might learn something. Find out what’s important to them and why. If they’re doing something repetitively as part of their job, try to make their life easier by including what’s most important to them. Do they really need to see the Created *and* Modified date of a document or do they just need the title and author? You’ll only find out after talking to them (or getting them drunk in a bar and leaving them in the back alley handcuffed to a garbage bin, don’t ask). Gotta Keep it Separated Hey, views are there for a reason. Use them. While “All Items” is a fine way to present a list of well, all items, it’s hardly sufficient to present a list of servers built before the Y2K bug hit. You’ll be scrolling the list for hours finally arriving at Page 387 of 12,591 and cursing that SharePoint guy for convincing you that putting your hardware into a list would be of any use to anyone. Next to collecting the data, presenting it is just as important. Views are often overlooked and many times ignored or misused. They’re the way you can slice and dice the data up so that you’re not trying to consume 3,000 years of human evolution on a single web page. Remember views can be filtered so feel free to create a view for each status or one for each operating system or one for each species of Information Worker you might be putting in that list or document library. Not only will it reduce the number of items someone sees at one time, it’ll also make the information that much more relevant. Also remember that each view is a separate page. Use it in navigation by creating a menu on the Quick Launch to each view. The discoverability of the Views menu isn’t overly obvious and if you violate the rule of columns (see Horizontally Scrolling below) the view menu doesn’t even show up until you shuffle the scroll bar to the left. Navigation links, big giant buttons, a screaming flashing “CLICK ME NOW” will help your users find their way. Sort It! Views are great so we’re building nice, rich views for the user. Awesomesauce. However sort is not very discoverable by the user. For example when you’re looking at a view how do you know if it’s ascending or descending and what is it sorted on. Maybe it’s sorted using two fields so what’s that all about? Help your users by letting them know the information they’re looking at is sorted. Maybe you name the view something appropriate like “Bogus Expense Claims Sorted By Deadbeats”. If you use the naming strategy just make sure you keep the name consistent with the description. In the previous example their better be a Deadbeat column so I can see the sort in action. Having a “Loser” column, while equally correct, is a little obtuse to the average Information Worker. Remember, they usually don’t use acronyms and even if they knew how to, it’s not immediately obvious to them that’s what you’re trying to convey. Another option is to simply drop a Content Editor Web Part above the list and explain exactly the view they’re looking at. Each view is it’s own page so one CEWP won’t be used across the board. Be descriptive in what the user is seeing but try to keep it brief. Dumping the first chapter of I, Claudius might be informative to the data but can gobble up screen real estate and miss the point of having the list. DO NOT Useless Attachments The attachments column is, in a word, useless. For the most part. Sure it indicates there’s an attachment on the list item but in the grand scheme of things that’s not overly informative. Maybe it is and by all means, if it makes sense to you include it. Colour it. Make it shine and stand like the Return of Clippy on every SharePoint list. Without it being functional it can be boring. EndUserSharePoint.com has an article to make the son of Clippy that much more useful so feel free to head over and check out this blog post by Paul Grenier on the task (Warning code ahead! Danger Will Robinson!) In any case, I would suggest you remove it from your views. Again if it’s important then include it but consider the jQuery solution above to make it functional. It’s added by default to views and one of things that people forget to clean up. Horizontal Scrolling Screen real estate is premium so building a list that contains 8,000 columns and stretches horizontally across 15 screens probably isn’t the most user friendly experience. Most users can’t figure out how to scroll vertically let alone horizontally so don’t make it even that more confusing for them. Take the Steve Krug approach in your view designs and try not to make the user think. Again views are your friend. Consider splitting up the data into views where one view contains 10 columns and other view contains the other 10. Okay, maybe your information doesn’t work that way but humans can only process 7 pieces of data at a time, 10 at most (then their heads explode and you don’t want to clean that mess up, especially on a Friday night before the big dance). It drives me batshit crazy when I see a view with 80 columns of data. I often ask the user “So what do you do with all this information”. The response is usually “With this data [the first 10 columns] I decide if I’m going to fire everyone, and with this data [the next 10 columns] I decide if I’m going to set the building on fire and collect the insurance”. It’s at that point I show them how to create two new views “People Who Are About To Get The Axe” and “Beach Time For The Executives”. Again, talk to your users and try to reason with them on cutting down the number of columns they see at once. Vertical Scrolling Another big faux pas I find is the use of multi-line comment fields in views. It’s not so bad when you have a statement like this in your view: “I really like, oh my god, thought I was going to scream when I saw this turtle then I decided what I was going to have for dinner and frankly I hate having to work late so when I was talking to the customer I thought, oh my god, what if the customer has turtles and then it appeared to me that I really was hungry so I'm going to have lunch now.” It’s fine if that’s the only column along with two or three others, but once you slap those 20 columns of data into the list, the comment field wraps and forms a new multi-page novel that takes up your entire screen. Do everyone a favour and just avoid adding the column to views. Train the user to just click through to the item if they need to see the contents. Duplicate Information Duplication is never good. Views and great as you can group data together. For example create a view of project status reports grouped by author. Then you can see what project manager is being a dip and not submitting their report. However if you group by author do you really need the Created By field as well in the view? Or if the view is grouped by Project then Author do you need both. Horizontal real estate is always at a premium so try not to clutter up the view with duplicate data like this. Oh  yeah, if you’re scratching your head saying “But Bil, if I don’t include the Project name in the view and I have a lot of items then how do I know which one I’m looking at”. That’s a hint that your grouping is too vague or you have too much data in the view based on that criteria. Filter it down a notch, create some views, and try to keep the group down to a single screen where you can see the group header at the top of the page. Again it’s just managing the information you have. Redundant, See Redundant This partially relates to duplicate information and smart columns but basically remember to not include the obvious in a view. Remember, don’t make me think. If you’ve gone to the trouble (and it was a lot of trouble wasn’t it?) to create separate views of your data by creating a “September Zombie Brain Sales”, “October Zombie Brain Sales”, etc. then please for the love of all that is holy do not include the Month and Product columns in your view. Similarly if you create a “My” view of anything (“My Favourite Brands of Spandex”, “My Co-Workers I Find The Urge To Disinfect”) then again, do not include the owner or author field (or whatever field you use to identify “My”). That’s just silly. Hope that helps! Happy customizing!

  • Node.js Adventure - Node.js on Windows

    - by Shaun
    Two weeks ago I had had a talk with Wang Tao, a C# MVP in China who is currently running his startup company and product named worktile. He asked me to figure out a synchronization solution which helps his product in the future. And he preferred me implementing the service in Node.js, since his worktile is written in Node.js. Even though I have some experience in ASP.NET MVC, HTML, CSS and JavaScript, I don’t think I’m an expert of JavaScript. In fact I’m very new to it. So it scared me a bit when he asked me to use Node.js. But after about one week investigate I have to say Node.js is very easy to learn, use and deploy, even if you have very limited JavaScript skill. And I think I became love Node.js. Hence I decided to have a series named “Node.js Adventure”, where I will demonstrate my story of learning and using Node.js in Windows and Windows Azure. And this is the first one.   (Brief) Introduction of Node.js I don’t want to have a fully detailed introduction of Node.js. There are many resource on the internet we can find. But the best one is its homepage. Node.js was created by Ryan Dahl, sponsored by Joyent. It’s consist of about 80% C/C++ for core and 20% JavaScript for API. It utilizes CommonJS as the module system which we will explain later. The official definition of Node.js is Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. First of all, Node.js utilizes JavaScript as its development language and runs on top of V8 engine, which is being used by Chrome. It brings JavaScript, a client-side language into the backend service world. So many people said, even though not that actually, “Node.js is a server side JavaScript”. Additionally, Node.js uses an event-driven, non-blocking IO model. This means in Node.js there’s no way to block currently working thread. Every operation in Node.js executed asynchronously. This is a huge benefit especially if our code needs IO operations such as reading disks, connect to database, consuming web service, etc.. Unlike IIS or Apache, Node.js doesn’t utilize the multi-thread model. In Node.js there’s only one working thread serves all users requests and resources response, as the ST star in the figure below. And there is a POSIX async threads pool in Node.js which contains many async threads (AT stars) for IO operations. When a user have an IO request, the ST serves it but it will not do the IO operation. Instead the ST will go to the POSIX async threads pool to pick up an AT, pass this operation to it, and then back to serve any other requests. The AT will actually do the IO operation asynchronously. Assuming before the AT complete the IO operation there is another user comes. The ST will serve this new user request, pick up another AT from the POSIX and then back. If the previous AT finished the IO operation it will take the result back and wait for the ST to serve. ST will take the response and return the AT to POSIX, and then response to the user. And if the second AT finished its job, the ST will response back to the second user in the same way. As you can see, in Node.js there’s only one thread serve clients’ requests and POSIX results. This thread looping between the users and POSIX and pass the data back and forth. The async jobs will be handled by POSIX. This is the event-driven non-blocking IO model. The performance of is model is much better than the multi-threaded blocking model. For example, Apache is built in multi-threaded blocking model while Nginx is in event-driven non-blocking mode. Below is the performance comparison between them. And below is the memory usage comparison between them. These charts are captured from the video NodeJS Basics: An Introductory Training, which presented at Cloud Foundry Developer Advocate.   Node.js on Windows To execute Node.js application on windows is very simple. First of you we need to download the latest Node.js platform from its website. After installed, it will register its folder into system path variant so that we can execute Node.js at anywhere. To confirm the Node.js installation, just open up a command windows and type “node”, then it will show the Node.js console. As you can see this is a JavaScript interactive console. We can type some simple JavaScript code and command here. To run a Node.js JavaScript application, just specify the source code file name as the argument of the “node” command. For example, let’s create a Node.js source code file named “helloworld.js”. Then copy a sample code from Node.js website. 1: var http = require("http"); 2:  3: http.createServer(function (req, res) { 4: res.writeHead(200, {"Content-Type": "text/plain"}); 5: res.end("Hello World\n"); 6: }).listen(1337, "127.0.0.1"); 7:  8: console.log("Server running at http://127.0.0.1:1337/"); This code will create a web server, listening on 1337 port and return “Hello World” when any requests come. Run it in the command windows. Then open a browser and navigate to http://localhost:1337/. As you can see, when using Node.js we are not creating a web application. In fact we are likely creating a web server. We need to deal with request, response and the related headers, status code, etc.. And this is one of the benefit of using Node.js, lightweight and straightforward. But creating a website from scratch again and again is not acceptable. The good news is that, Node.js utilizes CommonJS as its module system, so that we can leverage some modules to simplify our job. And furthermore, there are about ten thousand of modules available n the internet, which covers almost all areas in server side application development.   NPM and Node.js Modules Node.js utilizes CommonJS as its module system. A module is a set of JavaScript files. In Node.js if we have an entry file named “index.js”, then all modules it needs will be located at the “node_modules” folder. And in the “index.js” we can import modules by specifying the module name. For example, in the code we’ve just created, we imported a module named “http”, which is a build-in module installed alone with Node.js. So that we can use the code in this “http” module. Besides the build-in modules there are many modules available at the NPM website. Thousands of developers are contributing and downloading modules at this website. Hence this is another benefit of using Node.js. There are many modules we can use, and the numbers of modules increased very fast, and also we can publish our modules to the community. When I wrote this post, there are totally 14,608 modules at NPN and about 10 thousand downloads per day. Install a module is very simple. Let’s back to our command windows and input the command “npm install express”. This command will install a module named “express”, which is a MVC framework on top of Node.js. And let’s create another JavaScript file named “helloweb.js” and copy the code below in it. I imported the “express” module. And then when the user browse the home page it will response a text. If the incoming URL matches “/Echo/:value” which the “value” is what the user specified, it will pass it back with the current date time in JSON format. And finally my website was listening at 12345 port. 1: var express = require("express"); 2: var app = express(); 3:  4: app.get("/", function(req, res) { 5: res.send("Hello Node.js and Express."); 6: }); 7:  8: app.get("/Echo/:value", function(req, res) { 9: var value = req.params.value; 10: res.json({ 11: "Value" : value, 12: "Time" : new Date() 13: }); 14: }); 15:  16: console.log("Web application opened."); 17: app.listen(12345); For more information and API about the “express”, please have a look here. Start our application from the command window by command “node helloweb.js”, and then navigate to the home page we can see the response in the browser. And if we go to, for example http://localhost:12345/Echo/Hello Shaun, we can see the JSON result. The “express” module is very populate in NPM. It makes the job simple when we need to build a MVC website. There are many modules very useful in NPM. - underscore: A utility module covers many common functionalities such as for each, map, reduce, select, etc.. - request: A very simple HTT request client. - async: Library for coordinate async operations. - wind: Library which enable us to control flow with plain JavaScript for asynchronous programming (and more) without additional pre-compiling steps.   Node.js and IIS I demonstrated how to run the Node.js application from console. Since we are in Windows another common requirement would be, “can I host Node.js in IIS?” The answer is “Yes”. Tomasz Janczuk created a project IISNode at his GitHub space we can find here. And Scott Hanselman had published a blog post introduced about it.   Summary In this post I provided a very brief introduction of Node.js, includes it official definition, architecture and how it implement the event-driven non-blocking model. And then I described how to install and run a Node.js application on windows console. I also described the Node.js module system and NPM command. At the end I referred some links about IISNode, an IIS extension that allows Node.js application runs on IIS. Node.js became a very popular server side application platform especially in this year. By leveraging its non-blocking IO model and async feature it’s very useful for us to build a highly scalable, asynchronously service. I think Node.js will be used widely in the cloud application development in the near future.   In the next post I will explain how to use SQL Server from Node.js.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

  • Modular programming is the method of programming small task or programs

    Modular programming is the method of programming small task or sub-programs that can be arranged in multiple variations to perform desired results. This methodology is great for preventing errors due to the fact that each task executes a specific process and can be debugged individually or within a larger program when combined with other tasks or sub programs. C# is a great example of how to implement modular programming because it allows for functions, methods, classes and objects to be use to create smaller sub programs. A program can be built from smaller pieces of code which saves development time and reduces the chance of errors because it is easier to test a small class or function for a simple solutions compared to testing a full program which has layers and layers of small programs working together.Yes, it is possible to write the same program using modular and non modular programming, but it is not recommend it. When you deal with non modular programs, they tend to contain a lot of spaghetti code which can be a pain to develop and not to mention debug especially if you did not write the code. In addition, in my experience they seem to have a lot more hidden bugs which waste debugging and development time. Modular programming methodology in comparision to non-mondular should be used when ever possible due to the use of small components. These small components allow business logic to be reused and is easier to maintain. From the user’s view point, they cannot really tell if the code is modular or not with today’s computers.

  • Installazione ATI Mobility Radeon HD 5650 su Ubuntu 11.10

    - by Antonio
    Salve a tutti, possiedo un portatile HP Pavillion dv6 3110 con scheda video dedicata ATI Mobility Radeon HD 5650 da 1 Giga ed ho installato da poco Ubuntu 11.10 Versione 64 bit. Ho seguito molte guide su internet per installare i driver per la mia scheda video ma nessuna ha dato esito positivo. Nella finestra "driver aggiuntivi" sono riuscito ad installare i "Driver grafici fglrx proprietari ATI/AMD" ma dopo il riavvio non riesco ad utilizzare correttamente la scheda video. Mentre i "Driver grafici fglrx proprietari ATI/AMD (aggiornamenti post-release)" non me li fa proprio installare segnalando un errore che riporto di seguito "L'installazione di questo driver non è riuscita.Consultare i file di registro per maggiori informazioni: /var/log/jockey.log". Ho pensato allora di scaricare direttamente dal sito di AMD gli ultimi driver rilasciati attraverso il pacchetto "amd-driver-installer-12-3-x86.x86_64.run", l'ho lanciato, ho seguito il wizard di installazione, l'installazione viene completata, digito "sudo aticonfig --initial" per la configurazione iniziale, ma al riavvio del pc appaiono soltanto scritte su schermo nero con una serie di "OK" e qualche "FAIL". Ho provato questa procedura anche per le versioni precedenti dei driver, ma il risultato è sempre lo stesso. Sono disperato. Riuscirò mai ad utilizzare la mia scheda video? Vi incollo per completezza ciò che mi appare all'esecuzione del comando "lspci -nn | grep VGA" per visualizzare i processori grafici presenti sul mio pc: 00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Madison [AMD Radeon HD 5000M Series] [1002:68c1] Grazie anticipatamente a coloro che potranno aiutarmi.

  • HTML5 game engine for a 2D or 2.5D RPG style "map walk"

    - by stargazer
    please help me to choose a HTML5 game engine or Javascript libraries I want to do the following in the game: when the game starts a part the huge map (full size of the map: about 7 screens) is shown. The map itself is completely designed in the editor mapeditor.org (or in some comparable editor - if you know a good alternative to mapeditor.org - let me know) and loaded at runtime or at design time. The game engine should support loading of isometric maps (well, in worst case only orthogonal maps will be sufficient) both "tile layer" and "object layer" from mapeditor.org should be supported. Scrolling/performance of this map should be fast enough. The map and the game should be either in 2D (orthogonal map) or in 2.5D (isometric map) The game engine should support movement of sprites with animation. Let say I have a sprite for "human" with animation sequences showing "walking" in 8 directions - it should be imported into game engine and should "walk" on the map without writing a lot of Javascript code. Automatic scrolling of the map the "human" nears the screen border. Collision detection, "solid" objects. The mapeditor.org supports properies on tiles. Let say I assign a "solid" property to some tiles in editor. It should be easy to check this "solid" property in the game engine and implement kind of "solid" behavior, so the animanted sprites do not walk through the walls. Collision detection - it should be easy to implement some custom functionality like "when sprite A is close to sprite B - call this function" Showing "dialogs" or popup windows on top of the map - should be easy to implement. Cross-browser audio support - (it is implemented quite well in construct 2 from scirra, so I'm looking for the comparable audio quality) The game itself is a king of RPG but without fighting scenes and without huge "inventory". The main character just walking on the map, discovers some things, there are dialogs and sounds. The functionality of this example from sprite.js http://batiste.dosimple.ch/sprite.js/tests/mapeditor/map_reader.html is very close to what I'm developing. But I'm not a Javascript guru (and a very lazy guy) and would like to write even less Javascript code as in the example...

  • How to check system performance?

    - by Woltan
    Hi all, I am a new Ubuntu user and really like the look and the features of the OS. However, I have a feeling that the performance could be better. With that I mean: Somehow the scrolling within firefox of sites seems laggy. I do not know how I should measure it but there is a difference. Not that it is unusable but it is aggravating. Java programs are running really slow. As a comparison (I know it is not a fair one), I tried to run a game using wine. The graphic specifications using windows were much higher (1600x1200) with a high level of detail, and in ubuntu with the lowest level of detail 1024x768 was the maximum. (My graphics card is a GeForce GTS 450 with 1gb RAM) Coming to my question: Is there a way to measure the performance of 3D acceleration, java applets, firefox scrolling etc. with a tool and compare it with lets say a windows OS or other users having almost the same hardware? Maybe it is a setup issue where some fundamental drivers are missing or something!? Any help, link, suggestion is appreciated! Cherio Woltan

  • ASP.NET ViewState Tips and Tricks #1

    - by João Angelo
    In User Controls or Custom Controls DO NOT use ViewState to store non public properties. Persisting non public properties in ViewState results in loss of functionality if the Page hosting the controls has ViewState disabled since it can no longer reset values of non public properties on page load. Example: public class ExampleControl : WebControl { private const string PublicViewStateKey = "Example_Public"; private const string NonPublicViewStateKey = "Example_NonPublic"; // DO public int Public { get { object o = this.ViewState[PublicViewStateKey]; if (o == null) return default(int); return (int)o; } set { this.ViewState[PublicViewStateKey] = value; } } // DO NOT private int NonPublic { get { object o = this.ViewState[NonPublicViewStateKey]; if (o == null) return default(int); return (int)o; } set { this.ViewState[NonPublicViewStateKey] = value; } } } // Page with ViewState disabled public partial class ExamplePage : Page { protected override void OnLoad(EventArgs e) { base.OnLoad(e); this.Example.Public = 10; // Restore Public value this.Example.NonPublic = 20; // Compile Error! } }

  • Spotlight: How Scandinavia's Largest Nuclear Power Plant Increased Productivity and Reduced Costs wi

    - by [email protected]
    Ringhals nuclear power plant, which is part of the Vattenfall Group, is located about 60 km south-west of the beautiful coastal city of Gothenburg in Sweden. A deep concern to reduce environmental impact coupled with an effort to increase plant safety and operational efficiency have led to a recent surge in investments and initiatives around plant modification and plant optimization at Ringhals. A multitude of challenges were faced by the users in various groups that were involved in these projects. First, it was very difficult for users to easily access complex and layered asset and engineering information, which was critical to increased productivity and completing projects on time. Moreover, the 20 or so different solutions that were being used to view various document formats, not only resulted in collaboration complexity but also escalated IT administration costs and woes. Finally, there was a considerable non-engineering community comprising non-CAD specialists that needed easy access to plant data in an effort to minimize engineering disruption. Oracle's AutoVue significantly simplified the ability to efficiently view and use digital asset information by providing a standardized visualization solution for the enterprise. The key benefits achieved by Ringhals include: Increased productivity of plant optimization and plant modification by 3% Saved around $ 500 K annually Cut IT maintenance costs by 50% by using a single solution Reduced engineering disruption by allowing non-CAD users easy access to digital plant data The complete case-study can be found here
