• Add an entry for Ubuntu on Windows 8 boot loader

  - by John

  I have installed Ubuntu 12.10 by creating free space in Windows 8 and then using that space to create 3 partitions, one for SWAP, one for GRUB (mounting point is /boot) and one for the actual OS. I did this so the Windows 8 boot loader wouldn't be overwritten in case I ever wanted to remove Ubuntu. I can still boot into Ubuntu if I select the boot loader from the BIOS. I want to add Ubuntu to the Windows 8 boot loader and I've been told to use EasyBCD. The issue with that is it doesn't actually direct Windows to the GRUB file, but rather to something like autogrub0.mri. I have found another programme called Visual BCD which will allow me to actually set the bootloader paths and drives. From here, I don't quite know what to do. I believe I have it set to the correct drive but I don't know if I'm directing to the right file. I think it's /boot/grub/x86_64-efi/grub.efi. I don't know if that's the right file, if I need to remove /boot or if the / need to be \ as that's what Windows uses. Sorry for such a lengthy post, please help!

• Semantic coupling vs. large class

  - by user106587

  I have hardware I communicate with via TCP. This hardware accepts ~40 different commands/requests with about 20 different responses. I've created a HardwareProxy class which has a TcpClient to send and receive data. I didn't like the idea of having 40 different methods to send the commands/requests, so I started down the path of having a single SendCommand method which takes an ICommand and returns an IResponse, this results in 40 different SpecificCommand classes. The problem is this requires semantic coupling, i.e. the method that invokes SendCommand receives an IResponse which it has to downcast to SpecificResponse, I use a future map which I believe ensures the appropriate SpecificResponse, but I get the impression this code smells. Besides the semantic coupling, ICommand and IResponse are essentially empty abstract classes (Marker Interfaces) and this seems suspicious to me. If I go with the 40 methods I don't think I have broken the single responisbility principle as the responsibility of the HardwareProxy class is to act as the hardware, which has all of these commands. This route is just ugly, plus I'd like to have Asynchronous versions, so there'd be about 80 methods. Is it better to bite the bullet and have a large class, accept the coupling and MarkerInterfaces for a smaller soultuion, or am I missing a better way? Thanks.

• can't get a good install:11.10 server

  - by jack

  I screwed up my partitioning aparently tring to get lvm and raid1 going. the machine is an intel dual core dt with 2 gig of ram and 2 sata drives, one 250g and the other 500g. This a build for my school in n.e. Thailand. we have 20+ clients now, a website, email. Our old server is dying fast and we are going to add another 12 stations next week. I really need some help here! 1. have onboard gigabit ethernet that aparently uses same driver as realtek 811c. I installed a pcie gigabit card also 811c. At several points the eth0 has accessed the internet fine, but the eth1 will not communicate. 2. I saw a "fix" for this online which from root: rmmod r8169. this imediately killed the working onboard card. 3.I tried to re-install 11.10 figuring that would re-install r8169. However I messed something up in my partitioning and can't get a clean boot now. 6. so I think after 12 re-installs or so and 2 days. I can get through it right if I can start over with clean drives, but I can't figure out how to empty them out what with soft raid and lvm partitions. seems like i've had it going well and then trying to fix that one little problem, i go backwards.Please help! please send email.-thanks

• What's the canonical process for backing up a website?

  - by Walkerneo

  This is going to sound terrible, but bear with me. I currently have a cron job that does a mysql dump, a git add all and commit, and a git push to bitbucket. I set this up almost a year ago, when I didn't know much about git, backups, and general web development and administration. I haven't had the time to fix this and do it properly, but the repo has now grown quite big from accumulating large temporary files from my forum, so now I have to do something and I want to do it properly this time around. What processes do semi-large websites and personal site admins use for backing up server content? Based on what I've learned since I set this up, what I'm currently think of doing is: Making changes on a development domain and committing the code frequently Archiving the entire site after a successful deployment from the development domain Having automatic daily database and user-content backups. I still like the idea of backing up sqldumps with git, though. I know git isn't a backup tool and that this is beyond its purpose, but the textual queries that are exported would be easily managed by git and would save a lot of space in archives.

• Is error suppression acceptable in role of logic mechanism?

  - by Rarst

  This came up in code review at work in context of PHP and @ operator. However I want to try keep this in more generic form, since few question about it I found on SO got bogged down in technical specifics. Accessing array field, which is not set, results in error message and is commonly handled by following logic (pseudo code): if field value is set output field value Code in question was doing it like: start ignoring errors output field value stop ignoring errors The reasoning for latter was that it's more compact and readable code in this specific case. I feel that those benefits do not justify misuse (IMO) of language mechanics. Is such code is being "clever" in a bad way? Is discarding possible error (for any reason) acceptable practice over explicitly handling it (even if that leads to more extensive and/or intensive code)? Is it acceptable for programming operators to cross boundaries of intended use (like in this case using error handling for controlling output)? Edit I wanted to keep it more generic, but specific code being discussed was like this: if ( isset($array['field']) ) { echo '<li>' . $array['field'] . '</li>'; } vs the following example: echo '<li>' . @$array['field'] . '</li>';

• Partition Alignment Confusion

  - by user170757

  I have a new Samsung 840 250GB SSD on the way, and I want to make sure that everything is running optimally after install. I've spent many frustrating hours on the internet trying to understand how I should align the partitions of the SSD when it arrives (and even how to partition everything; my other drive is a 1TB HDD with files already on it). I'd like to know a foolproof way of setting everything up. Now, the only place I could find the erase block size of the 840 is here: http://thessdreview.com/Forums/ssd-beginners-guide-discussion/3630.htm I simply can't understand why such information isn't made freely accessible by manufacturers! But, anyway, this would suggest the EBS is 1536kb, which seems odd to me. It is to my understanding that you should now align by MiB (usually set at 1MiB). I assume that the figure above should actually be 1536k B=1.5MiB? This seems to suggest the partition alignment will be somewhat non-standard. So my question is: How do I align my partitions given this information? Please bear in mind that I have never used linux before; I'm doing my best to get everything set up so that I can begin to learn but am finding this process incredibly opaque and time consuming. If possible, a step by step guide through GParted would be great; at the moment I'm considering an NTFS partition ~20GB for Windows (playing games), an EXT4 ~20GB for ubuntu (for doing everything else) and a shared documents+games partition for everything else in NTFS file format. I'm not going to have any swap partition and use swap files instead.

• Tumblr custom domain not redirecting properly

  - by Manic

  I decided to host my blog at Tumblr, using their custom domain setup (http://blog.smokingfishgames.com/ instead of http://smokingfishgames.tumblr.com). However, it's been 72 hours and I'm still getting spotty redirection. It works some of the time--I go and see the page and blog, and it's all fine. However, it occasionally just stops working and redirects back to my web host, which is a directory with nothing but a single file called BUGGER.html (which I stuck in to make sure that it was my web host and not some Tumblr empty directory). Clearing the Chrome DNS cache makes the problem go away--for a while. After a few minutes, or an hour, or however long, I'll start seeing BUGGER.html again. I clear the cache, and poof, the blog shows up. The thing that's curious to me is that when I clear the cache and get BUGGER.html again (which happens occasionally), I can look at my Chrome DNS cache and see assets.tumblr.com UNSPECIFIED blog.smokingfishgames.com UNSPECIFIED www.tumblr.com UNSPECIFIED IP addresses and expiration times omitted for brevity's sake--if they're important I'm sure I can replicate the issue. This implies, to me anyway, that my browser is reaching Tumblr but getting bounced back to my web host. Any reason why this would be happening, or is this a normal symptom of DNS propagation? If it is a problem, should I be bothering Tumblr or my host with it, or is this something I can fix myself?

• Have Windows Automatically Login Without Entering Your Password

  - by deadlydog

  If you are like me and don't want to have to enter your password each time Windows loads, you can have Windows start up without prompting you to enter a user name or password.  The simple (and BAD) way to do this is to simply not have a password on your user account, but that’s a big security risk and will allow people to easily remote desktop into your computer. So, first set a password on your windows account if you don’t already have one.  Then select Run... from the start menu (or use Windows Key + R to open the Run window) and type control userpasswords2, which will open the user accounts application.   On the Users tab, clear the box for Users must enter a user name and password to use this computer, and click on OK. An Automatically Log On dialog box will appear; enter the user name and password for the account you want to use to automatically log into Windows.  That's it.    You may also want to make sure your screen saver is not set to prompt you for a password when it exits either. Now your computer is secure without getting in your way.

• Simple Interactive Search with jQuery and ASP.Net MVC

  - by Doug Lampe

  Google now has a feature where the search updates as you type in the search box.  You can implement the same feature in your MVC site with a little jQuery and MVC Ajax.  Here's how: Create a javascript global variable to hold the previous value of your search box. Use setTimeout to check to see if the search box has changed after some interval.  (Note: Don't use setInterval since we don't want to have to turn the timer off while Ajax is processing.) Submit the form if the value is changed. Set the update target to display your results. Set the on success callback to "start" the timer again.  This, along with step 2 above will make sure that you don't sent multipe requests until the initial request has finished processing. Here is the code: <script type="text/javascript"> var searchValue = $('#Search').val(); $(function () {     setTimeout(checkSearchChanged, 0.1); }); function checkSearchChanged() {     var currentValue = $('#Search').val();     if ((currentValue) && currentValue != searchValue && currentValue != '') {         searchValue = $('#Search').val();         $('#submit').click();     }     else {         setTimeout(checkSearchChanged, 0.1);     } } </script> <h2>Search</h2> <% using (Ajax.BeginForm("SearchResults", new AjaxOptions { UpdateTargetId = "searchResults", OnSuccess = "checkSearchChanged" })) { %>     Search: <%   = Html.TextBox("Search", null, new { @class = "wide" })%><input id="submit" type="submit" value="Search" /> <% } %> <div id="searchResults"></div> That's it!

• Maker Faire Report - Teaching Kids Java SE Embedded for Internet of Things (IoT)

  - by hinkmond

  I had a great time at this year's Maker Faire 2014 in San Mateo, Calif. where Jake Kuramoto and the AppsLab crew including Noel Portugal, Anthony Lai, Raymond, and Tony set up a super demo at the DiY table. It was a simple way to learn how Java SE Embedded technology could be used to code the Internet of Things (IoT) devices on the table. The best part of our set-up was seeing the kids sit down and do some coding without all the complexity of a Computer Science course. It was very encouraging to see how interested the kids were when walking them through the programming steps, then seeing their eyes light up when telling them, "You just coded a Java enabled Internet of Things device!" as the Raspberry Pi-connected devices turned on or started to move from their Java Embedded program. See: The AppsLab at Maker Faire It will be interesting to see how this next generation of kids grow up with all these Internet of Things devices around them and watch how they will program them. Hopefully, they will be using Java SE Embedded technology to do so. From the looks of it at this year's Maker Faire, we might have a bunch of motivated young Java SE Embedded coders coming up the ranks soon. Well, they have to get through middle school first, but they're on their way! Hinkmond

• Dualboot Asus n56v (ubuntu / win 7 x64) - ubuntu doesn't detect partition table made by windows

  - by user76439

  I have an Asus n56v and I've got troubles installing Ubuntu 12.04 x64. I already have installed Windows 7 x64! The hard drive is: Hitachi HTS547575A9E384 My problem: The installation program doesn't recognize the already existing partitions and is offering only options where there are partitions. Can someone help me out? Is this an ACPI/IDE conflict, missing driver or conflict with Windows 7? (I'm not an expert on Linux, only working sometimes with it.) I now tried out some options concerning EFI with a GTP-table. Everything worked but I wasn't able to fix a dual boot (Windows boot loader) nor with GRUB2. The laptop is still having a BIOS, but is able to boot DVDs/CDs in EFI-mode. Now I try to avoid EFI and GTP using the old windows MBR style. I reinstalled Windows, so far no problem. When I want to try to install Ubuntu, it doesn't detect the already existing partition table. It is just showing me an empty space for the whole disk. Other threads like Ubuntu 12.04 does not see windows already install on my computer (dual installation) don't help me out. os-prober shows me a correct result. I don't know how to deal with gdisk as shown in Installer doesn't detect existing partition table/windows 7 partition. I have 750GB for the whole disk. I'm using: 90GB for Windows reserved partition + system partition, 500GB for data and the rest should be for SWAP and linux-system. How can I make Ubuntu detect the partition table?

• Changing the Default Windows Phone 7 Deployment Target In Visual Studio 2010

  - by mbcrump

  After you download and install the January 2011 Windows Phone update, you will notice one annoying thing. The default deployment target for Windows Phone Projects in Visual Studio changes to Windows Phone 7 Device. Before the update, it defaulted to the Emulator. I found this extremely annoying as I’m more than likely going to test with the emulator before putting it on my actual device. Now to make things fair, Microsoft told you they were going to switch the default and even provided a solution, but you will have to check a tiny paragraph in the release notes. The good news is that its very easy to do: Simply navigate out to : %LocalAppData%\Microsoft\Phone Tools\CoreCon See the folder named, “10.0”? Go ahead and delete it. Now, the folder will be completely empty and if you fire up Visual Studio 2010 you will see we are now defaulting to the Emulator again. In my opinion, this should have been left at Emulator. Now, new WP7 developers will get a build error when they first start a WP7 project and will not know why until they read the error list.  Subscribe to my feed CodeProject

• Sprite sorting issues

  - by TheBroodian

  I apologize for the vague title, I'm not sure how else to phrase this problem. I am using tIDE to assist me in my game's world development. To give a dynamic effect to map layers within tIDE, it has events that can be wired up to draw sprites before or after the draw of layers, to create foreground or background effects during runtime. This all works fine and well, however, the only way that I understand that this works, is by calling tIDE's internal spritebatch to create this effect. This creates a problem for me, because within tIDE's source code, its spritebatch's call block is set to SpriteSortMode.Deferred, and my characters have particle elements that I would like to draw in front of and behind themselves, via a drawdepth value. I can use a separate instance of spritebatch and call my character's draw method, and set sprite sorting there, but then my character is drawn ontop of all layers in my tIDE map. Which is even worse to me than my particles not being drawn as I want them to be. So, in summary, I want all of my crap to work, but at the moment the only way I can figure to do that is to ghetto rig the spritebatch within my characters' draw methods by calling a spritebatch.End();, then starting a new call to Begin() with SpriteSortMode.BackToFront, doing all of my characters' draw logic, and then calling another spritebatch.End(); followed once again by a new spritebatch.Begin(). Obviously that is pretty undesirable, but I don't know any other feasible alternatives. Anybody got any wisdom they could impart unto me as to how I could handle this?

• Disabling monitor reconfiguration when closing lid

  - by Tomas

  I often need to move my laptop from one working place to another. When I do this, there are two events Ubuntu responds to by changing the monitor set up: Removing/attaching the VGA cable Closing/opening the lid of the laptop While removing the VGA cable gives me what I need (single screen, highest native resolution on the external screen if connected; otherwise highest resolution on the laptop), the laptop close/open lid response is not as good. Every time I close or open the lid, Ubuntu reconfigures the monitor set up. When I close the lid now... the screen goes black for a few seconds and it switches to clone, with my laptop screen disabled. Reopening results in... briefly a black screen, then the external monitor being used as desktop extension. Ubuntu thinks too much. My first and foremost question: Is there any way to let Ubuntu ignore lid close events? Ideally (or when there's no way to solve above question) I'd want to change how it deals with the screen reconfiguration. Why does Ubuntu toggle the screen configuration between external, clone and single display? Can't I just configure it to always use the external monitor, when present, in single screen mode? Note that similar questions have been asked before (most notably this one), but these have been closed perhaps wrongly. Any ideas are very welcome, I don't mind playing around a bit to see if something works.

• Unsure about TRIM enabled on my SSD

  - by user84750

  I have a SSD OCZ Vertex4 installed on my laptop. I'm running Ubuntu 12.04 LTS. I have enable TRIM by adding "discard" to my fstab file. (also added option noatime). I rebooted my Ubuntu and followed These instructions here to test TRIM. The end results of my tempfile was all ffff's, when it should have read all zero's, which is telling me TRIM is not really working or enabled correctly. Did I miss something? Also, will it be a problem if only my /home directory is encrypted. AND if you ask why I have swap on my SSD, it's because I let Ubuntu set up my partition. When I have my SSD, I just wanted to install Ubuntu as fast as possible. =) I've done testing to see at which point it will start to use swap and it took a lot of applications open to finally use swap. I currently have 4 GB of memory. I might shrink this to like 512 MB or 1 GB the most. Here's some info about my file system setup. sudo hdparm -I /dev/sda1 | grep "TRIM supported" Data Set Management TRIM supported (limit 16 blocks) sudo fdisk -l /dev/sda Device Boot Start End Blocks Id System /dev/sda1 * 2048 242016255 121007104 83 Linux /dev/sda2 242018302 250068991 4025345 5 Extended /dev/sda5 242018304 250068991 4025344 82 Linux swap / Solaris ls /dev/mapper control cryptswap1

• Build vs Rebuild

  - by prash

  Build means compile and link only the source files that have changed since the last build, while Rebuild means compile and link all source files regardless of whether they changed or not. Build is the normal thing to do and is faster. Sometimes the versions of project target components can get out of sync and rebuild is necessary to make the build successful. In practice, you never need to Clean. Build or Rebuild Solution builds or rebuilds all projects in the your solution, while Build or Rebuild <project name> builds or rebuilds the StartUp project. To set the StartUp project, right click on the desired project name in the Solution Explorer tab and select Set as StartUp project. The project name now appears in bold. Compile just compiles the source file currently being edited. Useful to quickly check for errors when the rest of your source files are in an incomplete state that would prevent a successful build of the entire project. Ctrl-F7 is the shortcut key for Compile. All source files that have changed are saved when you request a build/rebuild, so you don't have to save them first. When you run your executable (F5 or Ctrl-F5), Visual Studio saves all your changed source files and builds anything that changed, so you don't need to explicitly do those steps every time. This allows for quick "trial and error" debugging. Incidentally, if you like those little Visual Studio keyboard shortcuts, you can download posters of the C# and the VB.Net ones, respectively (I am personally a big fan of using keyboard shortcuts :) ).   Visual Studio 2010 http://www.microsoft.com/downloads/en/details.aspx?FamilyID=92ced922-d505-457a-8c9c-84036160639f   Visual Studio 2005 C#: http://www.microsoft.com/downloads/details.aspx?FamilyID=c15d210d-a926-46a8-a586-31f8a2e576fe&DisplayLang=en VB.NET: http://www.microsoft.com/downloads/details.aspx?FamilyID=6bb41456-9378-4746-b502-b4c5f7182203&DisplayLang=en

• Subdomain redirect to WWW

  - by manix

  I have the domain example.com and the test.example.com running on apache server. For some reason when I try to visit test.example it is redirected to www.test.example and by consequence a Server not found error is displayed in the browser. Both .htaccess (root and subdomain folder) files are empty. Additional facts I have another subdomain xyz.example.com pointed to public_html/xyz directory with some content inside (index.html with "hello world message") and it works fine if I use xyz.example.com instead of www.xyz.example.com. So, can you help me to point to the right direction in order. I have a vps and I am able to change any file if is required.

• WCF REST Error Handler

  - by Elton Stoneman

  I’ve put up on GitHub a sample WCF error handler for REST services, which returns proper HTTP status codes in response to service errors.   The code is very simple – a ServiceBehavior implementation which can be specified in config to tag the RestErrorHandler to a service. Any uncaught exceptions will be routed to the error handler, which sets the HTTP status code and description in the response, based on the type of exception.   The sample defines a ClientException which can be thrown in code to indicate a problem with the client’s request, and the response will be a status 400 with a friendly error message:       throw new ClientException("Invalid userId. Must be provided as a positive integer");   - responds:   Request URL http://localhost/Sixeyed.WcfRestErrorHandler.Sample/ErrorProneService.svc/lastLogin?userId=xyz   Error Status Code: 400, Description: Invalid userId. Must be provided as a positive integer   Any other uncaught exceptions are hidden from the client. The full details are logged with a GUID to identify the error, and the response to the client is a status 500 with a generic message giving them the GUID to follow up on:       var iUserId = 0;     var dbz = 1 / iUserId;   - logs the divide-by-zero error and responds:   Request URL http://localhost/Sixeyed.WcfRestErrorHandler.Sample/ErrorProneService.svc/dbz     Error Status Code: 500, Description: Something has gone wrong. Please contact our support team with helpdesk ID: C9C5A968-4AEA-48C7-B90A-DEC986F80DA5   The sample demonstrates two techniques for building the response. For client exceptions, a friendly HTML response is sent in the body as well as the status code and description. Personally I prefer not to do that – it doesn’t make sense to get a 400 error and find text/html when you’re expecting application/json, but it’s easy to do if that’s the functionality you want. The other option is to send an empty response, which the sample does with server exceptions.   The obvious extension is to have multiple exceptions representing all the status codes you want to provide, then your code is as simple as throwing the relevant exception – UnauthorizedException, ForbiddenExeption, NotImplementedException etc – anywhere in the stack, and it will be handled nicely.

• 2D Camera Acceleration/Lag

  - by Cyral

  I have a nice camera set up for my 2D xna game. Im wondering how I should make the camera have 'acceleration' or 'lag' so it smoothly follows the player, instead of 'exactly' like mine does now. Im thinking somehow I need to Lerp the values when I set CameraPosition. Heres my code private void ScrollCamera(Viewport viewport) { float ViewMargin = .35f; float marginWidth = viewport.Width * ViewMargin; float marginLeft = cameraPosition.X + marginWidth; float marginRight = cameraPosition.X + viewport.Width - marginWidth; float TopMargin = .3f; float BottomMargin = .1f; float marginTop = cameraPosition.Y + viewport.Height * TopMargin; float marginBottom = cameraPosition.Y + viewport.Height - viewport.Height * BottomMargin; Vector2 CameraMovement; Vector2 maxCameraPosition; CameraMovement.X = 0.0f; if (Player.Position.X < marginLeft) CameraMovement.X = Player.Position.X - marginLeft; else if (Player.Position.X > marginRight) CameraMovement.X = Player.Position.X - marginRight; maxCameraPosition.X = 16 * Width - viewport.Width; cameraPosition.X = MathHelper.Clamp(cameraPosition.X + CameraMovement.X, 0.0f, maxCameraPosition.X); CameraMovement.Y = 0.0f; if (Player.Position.Y < marginTop) //above the top margin CameraMovement.Y = Player.Position.Y - marginTop; else if (Player.Position.Y > marginBottom) //below the bottom margin CameraMovement.Y = Player.Position.Y - marginBottom; maxCameraPosition.Y = 16 * Height - viewport.Height; cameraPosition.Y = MathHelper.Clamp(cameraPosition.Y + CameraMovement.Y, 0.0f, maxCameraPosition.Y); }

• FP for simulation and modelling

  - by heaptobesquare

  I'm about to start a simulation/modelling project. I already know that OOP is used for this kind of projects. However, studying Haskell made me consider using the FP paradigm for modelling a system of components. Let me elaborate: Let's say I have a component of type A, characterised by a set of data (a parameter like temperature or pressure,a PDE and some boundary conditions,etc.) and a component of type B, characterised by a different set of data(different or same parameter, different PDE and boundary conditions). Let's also assume that the functions/methods that are going to be applied on each component are the same (a Galerkin method for example). If I were to use an OOP approach, I would create two objects that would encapsulate each type's data, the methods for solving the PDE(inheritance would be used here for code reuse) and the solution to the PDE. On the other hand, if I were to use an FP approach, each component would be broken down to data parts and the functions that would act upon the data in order to get the solution for the PDE. This approach seems simpler to me assuming that linear operations on data would be trivial and that the parameters are constant. What if the parameters are not constant(for example, temperature increases suddenly and therefore cannot be immutable)? In OOP, the object's (mutable) state can be used. I know that Haskell has Monads for that. To conclude, would implementing the FP approach be actually simpler,less time consuming and easier to manage (add a different type of component or new method to solve the pde) compared to the OOP one? I come from a C++/Fortran background, plus I'm not a professional programmer, so correct me on anything that I've got wrong.

• Transparent JPanel, Canvas background in JFrame

  - by Andy Tyurin

  I wanna make canvas background and add some elements on top of it. For this goal I made JPanel as transparent container with setOpaque(false) and added it as first of JFrame container, then I added canvas with black background (in future I wanna set animation) to JFrame as second element. But I can't undestand why i see grey background, not a black. Any suggestions? public class Game extends JFrame { public Container container; //Game container with components public Canvas backgroundLayer; //Background layer of a game public JPanel elementsLayer; //elements panel (top of backgroundLayer), holds different elements private Dimension startGameDimension = new Dimension(800,600); //start game dimension public Game() { //init main window super("Astra LaserForces"); setSize(startGameDimension); setBackground(Color.CYAN); container=getContentPane(); container.setLayout(null); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //init jpanel elements layer elementsLayer=new JPanel(); elementsLayer.setSize(startGameDimension); elementsLayer.setBackground(Color.BLUE); elementsLayer.setOpaque(false); container.add(elementsLayer); //init canvas background layer backgroundLayer = new Canvas(); backgroundLayer.setSize(startGameDimension); backgroundLayer.setBackground(Color.BLACK); //set default black color container.add(backgroundLayer); } //start game public void start() { setVisible(true); } //create new instance of game and start it public static void main(String[] args) { new Game().start(); } }

• XNA 4.0 - Purple/Pink Tint Over All Sprites After Viewing in FullScreen

  - by D. Dubya

  I'm a noob to the game dev world and recently finished the 2D XNA tutorial from http://www.pluralsight.com. Everything was perfect until I decided to try the game in Fullscreen mode. The following code was added to the Game1 constructor. graphics.PreferredBackBufferWidth = 800; graphics.PreferredBackBufferHeight = 480; graphics.IsFullScreen = true; As soon as it launched in Fullscreen, I noticed that the entire game was tinted. None of the colours were appearing as they should. That code was removed, the game then launched in the 800x480 window, however the tint remained. I commented out all my Draw code so that all that was left was GraphicsDevice.Clear(Color.CornflowerBlue); //spriteBatch.Begin(); //gameState.Draw(spriteBatch, false); //spriteBatch.End(); //spriteBatch.Begin(SpriteSortMode.Deferred, BlendState.Additive); //gameState.Draw(spriteBatch, true); //spriteBatch.End(); base.Draw(gameTime); The result was an empty window that was tinted Purple, not Blue. I changed the GraphicsDevice.Clear colour to Color.White and the window was tinted Pink. Color.Transparent gave a Black window. Even tried rebooting my PC but the 'tint' still remains. I'm at a loss here.

• Brightness going up to 100% on loading certain websites in Chrome

  - by picheto

  I'm using Google Chrome version 21.0.1180.89 on Ubuntu 12.04 and my laptop is a Sony VAIO VPCCW15FL (spec sheet). My video driver is the propietary "NVIDIA accelerated graphics driver (post-release updates)(version-current updates)". After installing Ubuntu, I discovered that neither the brightness control buttons (hardware) or the brightness slider (software) worked, and found out I could get the hardware buttons to work by installing the nvidiabl.deb package and oBacklight script. I'm using nvidiabl-dkms 0.77 and oBacklight 0.3.8. Still, the slider on the Ubuntu "Settings" does not work, but I don't care. There is an annoying thing happening when loading certain pages in Google Chrome: the brightness goes up to 100% when loading the webpage or when leaving it (closing the tab or typing a different URL on the omnibox). However, the "brightness tooltip" (that default brightness notification) remembers the position it was set to, so if I adjust the brightness with the HW buttons, the level gets adjusted relative to the value it was set to before "going 100%". I disabled the flash PPAPI plugin, but left the NPAPI plugin enabled, and the problem went away for pages with flash content. Still, the same thing happens when viewing HTML5 video, or when loading, for example, the Chrome Web Store or using the Scratchpad extension. I suppose it has to do with the rendering of certain elements using the GPU, but this is just a guess. This brightness thing does not happen when using Firefox 15.0 or any other application I have used yet. Does anybody know why this may be happening and what could I do to fix this without changing browser? Thanks a lot.
