  • 12 Steps to NTFS Shared Folders in Windows Server 2012

    - by KeithMayer
    In the past, managing and sharing NTFS folders could be a real ordeal – there were different tools for managing NTFS permissions vs shared folders and most IT Pros generally used these tools on a server-by-server basis from each server’s console. Server Manager to the rescue! In Windows Server 2012, Server Manager provides a management facelift on top of the disconnected process that we’ve used in the past for sharing folders and setting NTFS permissions. In addition, Server Manager can

  • How to Send the Contents of the Clipboard to a Text File via the Send to Menu

    - by Jason Faulkner
    We have previously covered how to send the contents of a text file to the Windows Clipboard with a simple Send To shortcut, but what if you want to do the opposite? That is: send the contents of the clipboard to a text file with a simple shortcut. No problem. Here’s how. Copy the ClipOut Utility While Windows offers the command line tool ‘clip’ as a way to direct console output to the clipboard, it does not have a tool to direct the clipboard contents to the console. To do this, we are going to use a small utility named ClipOut (download link at the bottom). Simply download and extract this file to a location in your Windows PATH variable (if you don’t know what this means, just extract the EXE to your C:\Windows folder) and you are ready to go. Add the Send To Shortcut Open your Send To folder location by going to Run > shell:sendto Create a new shortcut with the command: CMD /C ClipOut > Note the above command will overwrite the contents of the selected file. If you would like to append to the contents of the selected file, use this command instead: CMD /C ClipOut >> Of course, you could make shortcuts for both. Give a descriptive name to the shortcut. You’re finished. Using this shortcut will now send the text contents copied to your Windows Clipboard to the selected file. It is important to note that the ClipOut tool only supports outputting text. If you had binary data copied to your clipboard, then the output would be empty. Changing the Icon By default, the icon for the shortcut will appear as a command prompt, but you can easily change this by editing the properties of the shortcut and clicking the Change Icon button. We used an icon located in “%SystemRoot%\System32\shell32.dll”, but any icon of your liking will do. As an additional tweak, you can set the properties of the shortcut to run minimized. This will prevent the command window from “blinking” when the send to command is run (instead it will blink in your taskbar, which is hardly noticeable). Links Download ClipOut Utility

  • Are Java's public fields just a tragic historical design flaw at this point?

    - by Avi Flax
    It seems to be Java orthodoxy at this point that one should basically never use public fields for object state. (I don't necessarily agree, but that's not relevant to my question.) Given that, would it be right to say that from where we are today, it's clear that Java's public fields were a mistake/flaw of the language design? Or is there a rational argument that they're a useful and important part of the language, even today? Thanks! Update: I know about the more elegant approaches, such as in C#, Python, Groovy, etc. I'm not directly looking for those examples. I'm really just wondering if there's still someone deep in a bunker, muttering about how wonderful public fields really are, and how the masses are all just sheep, etc. Update 2: Clearly static final public fields are the standard way to create public constants. I was referring more to using public fields for object state (even immutable state). I'm thinking that it does seem like a design flaw that one should use public fields for constants, but not for state… a language's rules should be enforced naturally, by syntax, not by guidelines.

  • StringBuffer behavior in LWJGL

    - by Michael Oberlin
    Okay, I've been programming in Java for about ten years, but am entirely new to LWJGL. I have a specific problem whilst attempting to create a text console. I have built a class meant to abstract input polling to it, which (in theory) captures key presses from the Keyboard object and appends them to a StringBuilder/StringBuffer, then retrieves the completed string after receiving the ENTER key. The problem is, after I trigger the String return (currently with ESCAPE), and attempt to print it to System.out, I consistently get a blank line. I can get an appropriate string length, and I can even sample a single character out of it and get complete accuracy, but it never prints the actual string. I could swear that LWJGL slipped some kind of thread-safety trick in while I wasn't looking. Here's my code: static volatile StringBuffer command = new StringBuffer(); @Override public void chain(InputPoller poller) { this.chain = poller; } @Override public synchronized void poll() { //basic testing for modifier keys, to be used later on boolean shift = false, alt = false, control = false, superkey = false; if(Keyboard.isKeyDown(Keyboard.KEY_LSHIFT) || Keyboard.isKeyDown(Keyboard.KEY_RSHIFT)) shift = true; if(Keyboard.isKeyDown(Keyboard.KEY_LMENU) || Keyboard.isKeyDown(Keyboard.KEY_RMENU)) alt = true; if(Keyboard.isKeyDown(Keyboard.KEY_LCONTROL) || Keyboard.isKeyDown(Keyboard.KEY_RCONTROL)) control = true; if(Keyboard.isKeyDown(Keyboard.KEY_LMETA) || Keyboard.isKeyDown(Keyboard.KEY_RMETA)) superkey = true; while(Keyboard.next()) if(Keyboard.getEventKeyState()) { command.append(Keyboard.getEventCharacter()); } if (Framework.isConsoleEnabled() && Keyboard.isKeyDown(Keyboard.KEY_ESCAPE)) { System.out.println("Escape down"); System.out.println(command.length() + " characters polled"); //works System.out.println(command.toString().length()); //works System.out.println(command.toString().charAt(4)); //works System.out.println(command.toString().toCharArray()); //blank line! System.out.println(command.toString()); //blank line! Framework.disableConsole(); } //TODO: Add command construction and console management after that } } Maybe the answer's obvious and I'm just feeling tired, but I need to walk away from this for a while. If anyone sees the issue, please let me know. This machine is running the latest release of Java 7 on Ubuntu 12.04, Mate desktop environment. Many thanks.

  • Client-side prediction for FPS

    - by newprogrammer
    People that understand client-side prediction and client-side interpolation, I have a question: When I play the game Team Fortress 2, and type cl_predict 1 into the developer's console, it enables client-side prediction. The also says "6 predictable entities reinitialized". It says this regardless of how many players are on the server, which makes sense, because other players are not predictable entities. I thought client-side prediction was only for the movement of the player. Are there other entities that the client can provide prediction for?

  • can't get past the login screen

    - by Greg
    Using a brand-new install to a usb stick of 12.04 lts installed by Universal USB Installer 1.8.9.8. I log in as "ubuntu" with a blank password, the console appears for a second or two with text scrolling past and then it returns to the login page. I've used the same usb stick on several computers with the same results, so it doesn't appear to be a hardware/driver issue. I have not tried installing to the hard drive, because I wanted to try it out first.

  • Collision rectangle response

    - by dotty
    I'm having difficulties getting a moveable rectangle to collide with more than one rectangle. I'm using SFML and it has a handy function called Intersect() which takes 2 rectangles and returns the intersections. I have a vector full of rectangles which I want my moveable rectangle to collide with. I'm looping through this using the following code (p is the moveble rectangle). IsCollidingWith returns a bool but also uses SFML's Interesect to work out the intersections. while(unsigned i = 0; i!= testRects.size(); i++){ if(p.IsCollidingWith(testRects[i]){ p.Collide(testRects[i]); } } and the actual Collide() code void gameObj::collide( gameObj collidingObject ){ printf("%f %f\n", this->colliderResult.width, this->colliderResult.height); if (this->colliderResult.width < this->colliderResult.height) { // collided on X if (this->getCollider().left < collidingObject.getCollider().left ) { this->move( -this->colliderResult.width , 0); }else { this->move( this->colliderResult.width, 0 ); } } if(this->colliderResult.width > this->colliderResult.height){ if (this->getCollider().top < collidingObject.getCollider().top ) { this->move( 0, -this->colliderResult.height); }else { this->move( 0, this->colliderResult.height ); } } } and the IsCollidingWith() code is bool gameObj::isCollidingWith( gameObj testObject ){ if (this->getCollider().intersects( testObject.getCollider(), this->colliderResult )) { return true; }else { return false; } } This works fine when there's only 1 Rect in the scene. However, when there's move than one Rect it causes issue when working out 2 collisions at once. Any idea how to deal with this correctly? I have uploaded a video to youtube to show my problem. The console on the far-right shows the width and height of the intersections. You can see on the console that it's trying to calculate 2 collisions at once, I think this is where the problem is being caused. The youtube video is at http://www.youtube.com/watch?v=fA2gflOMcAk also , this image also seems to illustrate the problem nicely. Can someone please help, I've been stuck on this all weekend!

  • What is the best objective way to measure language popularity trends? (What's better than TIOBE?)

    - by Eric Wilson
    The best way to get data on computer language popularity that I know is the TIOBE index. But everyone knows that TIOBE is hopelessly flawed. (If someone provides a link to support this, I'll add it here.) So is there any data on programming language popularity that is generally considered meaningful? The only other option I know is to look at the trends at indeed.com, which is inherently flawed, being based on job postings. It isn't like I would make a future language decision solely based on an index, but it might provide a useful balance to the skewed perspective one obtains by talking to ones friends and colleagues. To illustrate that bias, I'll point out that based on the experience of those I personally know, the only languages used professionally today (in order of popularity) are Java, C#, Groovy, JavaScript, Ruby, Objective C, and Perl. (Though it is evident that C, C++ and PHP were used in the past.) So my question is, everyone bashes TIOBE, but is there anything else? If so, can anyone explain how we know the alternative has better methodology? Thanks.

  • Running Assemblies in custom application domains

    This sounds like a deep technical thing and internally it's right too. But in a developer prospective, if he needs to run an assembly under a fresh new ApplicationDomain, it's so easy like just use some of the classes defined in System NameSpace. Below I am explaining this with a small console application.

  • Copying Properties between 2 Different Types&hellip;

    - by Shawn Cicoria
    I’m not sure where I had seen some of this base code, but this comes up time & time again on projects. Here’s a little method that copies all the R/W properties (public) between 2 distinct class definitions: It’s called as follows: private static void Test1() { MyClass obj1 = new MyClass() { Prop1 = "one", Prop2 = "two", Prop3 = 100 }; MyOtherClass obj2 = null; obj2 = CopyClass(obj1); Console.WriteLine(obj1); Console.WriteLine(obj2); } namespace Space1 { public class MyClass { public string Prop1 { get; set; } public string Prop2 { get; set; } public int Prop3 { get; set; } public override string ToString() { var rv = string.Format("MyClass: {0} Prop2: {1} Prop3 {2}", Prop1, Prop2, Prop3); return rv; } } } namespace Space2 { public class MyOtherClass { public string Prop1 { get; set; } public string Prop2 { get; set; } public int Prop3 { get; set; } public override string ToString() { var rv = string.Format("MyOtherClass: {0} Prop2: {1} Prop3 {2}", Prop1, Prop2, Prop3); return rv; } } Source of the method: /// /// Provides a Copy of Public fields between 2 distinct classes /// /// Source class name /// Target class name /// Instance of type Source /// An instance of type Target copying all public properties matching name from the Source. public static T CopyClass(S source) where T : new() { T target = default(T); BindingFlags flags = BindingFlags.Public | BindingFlags.Instance; if (source == null) { return (T)target; } if (target == null) target = new T(); PropertyInfo[] objProperties = target.GetType().GetProperties(flags); foreach (PropertyInfo pi in objProperties) { string name = pi.Name; PropertyInfo sourceProp = source.GetType().GetProperty(name, flags); if (sourceProp == null) { throw new ApplicationException(string.Format("CopyClass - object type {0} & {1} mismatch in property:{2}", source.GetType(), target.GetType(), name)); } if (pi.CanWrite && sourceProp.CanRead) { object sourceValue = sourceProp.GetValue(source, null); pi.SetValue(target, sourceValue, null); } else { throw new ApplicationException(string.Format("CopyClass - can't read/write a property object types {0} & {1} property:{2}", source.GetType(), target.GetType(), name)); } } return target; }

  • BizTalk Orchestration & Port Tutorial Part 2

    - by bosuch
    In Part 1 I showed how to create and publish a simple Orchestration demo. Now we’ll finish configuring it in the admin console and test it. Open the BizTalk Server 2009 Administration Console, and expand BizTalk Server 2009 Administration, then Applications. You should have an entry for OrchestrationPortDemo – expand it as well. First, we’ll add the Receive Port – the place that we’ll drop the test file. Right-click on Receive Ports and select New One-way Receive Port. On the General tab, name it InputPort, then click over to Receive Locations.   Click New to add a new location. Your receive location can be FTP, SQL, WCF, SharePoint, or many other choices, but for this demo we’ll add a File location. Click the Configure button and set a receive folder (something like “C:\PortDemo\”) and a file mask (stick with “*.xml” for now) and click OK three times to create your Receive Port.   Next we’ll create the Send port – the location where BizTalk will drop the file. Right-click on Send Ports and choose New Static One-way Send Port. Give it an appropriate name, and configure the FILE Transport Properties as shown:   Click OK twice and your Send Port will be created. Now we’ll configure the Orchestration Bindings. Click on Orchestrations, then right-click the orchestration itself and select Properties. Select the Bindings tab. Choose BizTalkServerApplication as the host, and select the Send and Receive ports you previously created, as shown:   Now it’s time to fire everything up. Right-click on the send port you created and click Start. Once the Status column displays “Started”, click on Receive Locations and Enable the Receive Location previously created. Finally, start the Orchestration. Now, time to test! Create a simple xml file like: <root>    <Node1>Test</Node1>    <Node2>Test</Node2> </root> And drop it into the C:\PortDemo folder. After a couple of seconds the file should disappear – this indicates BizTalk has picked it up for processing. Look in the C:\PortDemo\Output folder and you should see an xml file with a GUID for a name, like {7C50104F-FC3E-4A49-B2FA-4F560A37636D}.xml. Open it to verify that it matches your input file. Practically, this demo doesn’t do a whole heck of a lot, but it shows you the basics for building, publishing and running an orchestration.

  • Recommended learning path?

    - by stairmast0r
    First, my current standing: I know C++ at an.. advanced beginner level? I've gone through a book, I know the syntax well enough, I know a fair amount of standard library functions, and I've programmed some simple console stuff with it. I'd probably be able to program more with it if I knew how to structure a program, but I just can't seem to wrap my head around the whole concept of structuring something remotely complex. I've messed around with Java for a day or two, and the syntax was extremely easy to get the hang of, except that I didn't really know any functions. I'm plenty willing to learn, and to work hard to do so, but I don't really know where to go from here. Now, at the risk of sounding cliche, what I'd like to become is someone like the great three of id; Carmack, Romero, and Abrash. To be considered a genius. I believe anything can be learned, and nothing mentally limits anyone except lack of desire to learn. But I don't know how to learn this. They learned by doing, and making do with what resources they had. On the other hand, I have access to almost any books I want, access to the internet, and access to a more than capable computer and software. Should I learn more languages? Assembly? LISP? BASIC? Haskell? Should I dive straight into advanced topics like OpenGL? Or should I wait until I feel I've come closer to mastering the simpler things, like console programs, first? Should I follow tutorials? Should I follow books? Should I just dive into writing something and follow a reference manual as I go? What order should I do all this in? How should I do it? I want to completely master this; to be considered a genius. The most perfect career I can imagine is to start the next id. I have the drive to do it, I just don't know where to begin...
