• Ubuntu 12.04 Freezes at Bootup

  - by Ryan Yu

  I have an Acer Aspire One Model AO722, that has a dual-boot configuration with Windows 7 Home Premium and Ubuntu 12.04. Processor: AMD C-50, 1.00GHz 2.00GB ram, 64-bit, AMD Radeon HD 6250 Graphics. I installed Ubuntu two days ago, and since then, loading it has been sporadic. Windows 7 still loads just fine, but Ubuntu will sometimes freeze. First time I booted Ubuntu up, it ran no problem. Worked with it for half an hour, then shut down the computer. The second time I booted it up, it froze after ten minutes when I was trying to set up Thunderbird. Third time, same thing. Fourth time, it froze about 5 minutes after bootup when I was trying to connect to my wifi. Fifth time, it ran no problems for about 5~ hours. Then, three consecutive times I've restarted (what is it, the 6th, 7th, and 8th times?) it has gotten to the login screen, I've entered my password, all the text on the page disappears as if its going to load my desktop, and it freezes. A minute ago when I booted Ubuntu up for the 9th time, it loaded the desktop fine. Who knows if it'll crash soon; probably, though. Any ideas?

• Mapping capslock to control on Mac OS X: works for some things, but not others?

  - by keflavich

  I've mapped my capslock key to control using the Modifier Keys mapping in System Preferences: Keyboard. I've also tried mapping to "right control" instead of "left control" as per http://hints.macworld.com/article.php?story=20060825072451882 using a plist editor. The mapping seems to work in all cases except one: I can't use capslock with left-shift to make key mappings or apparently do anything else. capslock (as control) with right-shift works. I'm primarily testing by using control-tab / control-shift-tab to switch between tabs. Using the on-screen-keyboard viewer, I can get capslock-shift-(just about anything) to work, but not capslock-leftshift-tab. My best guess is that somehow the particular keyboard I'm working on is faulty, but I'm curious whether anyone else can reproduce this or has any ideas.

• Start vino-server (VNC) before login on Linux CentOS

  - by Dr. Gianluigi Zane Zanettini

  I'm using the default vino-server package to access my CentOS 6 workstation via VNC. It works ok, but only AFTER I locally login on the workstation. I need to have vino-server start BEFORE the login, right at the Gnome login screen where I choose username and password. Due to personal reasons, I need to use Vino and not vnc-server or any other packages. I already tried to insert /usr/libexec/vino-server & in /etc/gdm/Init/Default but this didn't solve the issue.

• Wordpress Automatic Updating/Installing Plugins Permissions

  - by karmic

  I am using the latest Wordpress and I have always had issues with the automatic updater. For the files in the wordpress directory, i set them to permission 770, and add the webserver user 'www-data' as the group owner. I use lighttpd. However, the automatic updating plugins or installing plugins does not work. It works if I chmod 777 the files or if I set the actual owner to the web server as well. What are the best permission settings for security while still allowing the updating feature to work properly in wordress? Also, by 'not work' i mean, it will go to the screen that asks me for FTP credentials when I try to update.

• How do I adjust the actual font sizes in Internet Explorer?

  - by Cyberherbalist

  I like having as much stuff on the screen at once as I can. But as a consequence of getting on in years, small font sizes are starting to become a problem. Internet Explorer has the ability to increase the font size of text in webpages (those pages that don't set the font size explicitly). On the main menu, it is View | Text Size. The choices are: Smallest, Smaller, Medium, Larger, Largest. Medium is on many web pages just a tad too small to me. But if I go to Larger the font size is way too big. My question is, is there a way to set these text size jumps differently from what they seem to be?

• Visual Studio 2012 first impressions...no Macros!

  - by bconlon

  Yesterday I installed Microsoft Visual Studio 2012 for the first time (all 8.5GB) and after 20 years of (mostly) happy times using VS they have removed Macros, one of the most handy features.The first thing I wanted to do when I upgraded my VS2010 project was to add a #elseif block to each file. This would usually be simple case of find in files of the previous #elseif and then Ctrl+Shift+R to record a macro which would be: F8 (to select the next file from find list), F3 (to find the correct position in file), Ctrl+V to paste the new code. Then all I would need to do is keep Ctrl+Shift+P (Play Macro) pressed until all the files were processed.But alas Ctrl+Shift+R does nothing! I won’t say that I use Macros every day but it was a very useful feature.To continue my moaning a little more, I also don't like the bland interface. This has been well documented by others, but now I have used it myself, I find it difficult to tell one grey area of screen from another and the lack of colour makes the icons unclear.I also don't see why the menus now need to SHOUT in capital letters?On the plus side, they have now added the ability to see WPF properties in the debugger...a bit of an oversight in Visual Studio 2010. Oh, but you still can't edit and continue on files that contain templated code.Whilst Visual Studio 2012 is not a complete disaster like Windows 8 (why develop a desk top OS to be the same as a Smart device OS), it does not float my boat.Rant over.#

• Browser-based Operating System

  - by Ross Peoples

  I have a bunch of touchscreen machines that I want to display a webpage on and have users interact with the webpage via the touchscreen. Right now, this is done with a full-blown OS with a browser set to run at startup. I think maybe the ideal solution is to use a Linux-based OS that boots up, starts X, then starts a web browser (Chrome, Firefox, or whatever) in full screen mode. What kind of options do I have? I really want to avoid using a full-blown OS like I do now. It looks unprofessional and takes a while to boot up. I was thinking maybe Chrome OS or something, but I wouldn't know how to set it up for my purposes, since it's still designed to be used as a desktop OS instead of a kiosk-type OS.

• Generic tool to configure startup applications on Unix

  - by srid

  Is there an automated deployment tool that manages startup applications on a variety of machines, especially the Unices? Or is the only hope to study the nuts and bolts of each Unix (osx, linux, solaris, hpux, aix) on how to configure applications to launch on system startup? I want to run them as a specific user, instead of root. At the moment, I run them all within a screen session .. which is a hassle, as this requires manual intervention every time the machine is rebooted for some reason. Ideally, I am looking for a tool that would read, say, ~/.startup-programs which file contains, on each line, the command line to launch the needed daemons. And this tool should work on OSX, Linux, Solaris, HPUX and AIX ... writing the appropriate startup scripts for each platform.

• OpenGL lighting with dynamic geometry

  - by Tank

  I'm currently thinking hard about how to implement lighting in my game. The geometry is quite dynamic (fixed 3D grid with custom geometry in each cell) and needs some light to get more depth and in general look nicer. A scene in my game always contains sunlight and local light sources like lamps (point lights). One can move underground, so sunlight must be able to illuminate as far as it can get. Here's a render of a typical situation: The lamp is positioned behind the wall to the top, and in the hollow cube there's a hole in the back, so that light can shine through. (I don't want soft shadows, this is just for illustration) While spending the whole day searching through Google, I stumbled on some keywords like deferred rendering, forward rendering, ambient occlusion, screen space ambient occlusion etc. Some articles/tutorials even refer to "normal shading", but to be honest I don't really have an idea to even do simple shading. OpenGL of course has a fixed lighting pipeline with 8 possible light sources. However they just illuminate all vertices without checking for occluding geometry. I'd be very thankful if someone could give me some pointers into the right direction. I don't need complete solutions or similar, just good sources with information understandable for someone with nearly no lighting experience (preferably with OpenGL).

• How to add a Mac to Windows Active Directory

  - by Ben Daniel

  I've gone into the Directory Utility on the mac, clicked on the services tab, entered the Active Directory Domain and Computer ID, clicked the Bind button and it showed a little status label which flickered through 5 of 5 steps and then said "An unknown error occurred". If I ignore the error and just click the OK button further down the screen and make sure the Active Directory service is ticked in the list of services, then go to the Directory Servers tab and try to add an Active Directory by entering my ad domain, computer id, admin username and password I get an error "Unable to add the domain. An unexpected error of type -14090 (eDSAuthFailed) occurred." Any ideas?

• Intel Rapid Start Driver Reinstallation doesn't work?

  - by elegantonyx

  I recently had to reformat my entire drive and reinstall Windows 7. Something that bothers me is that when I was downloading the Intel Rapid Start driver (I have a Lenovo Ideapad Y480, and it comes standard with the Rapid Start) and tried to install it, the installer claimed that my system did not meet the requirements in order to install, when it was previously installed by the OEM. My startup times have increased from 21 seconds to log-in screen to 50 seconds. Please help... Specs: Lenovo Ideapad Y480 Intel Core i7-3610 Ivy Bridge (quad-core) Nvidia Geforce 640M LE with 2gb VRAM 8GB RAM 1TB hard drive, 32 GB SSD (OEM installed)

• Windows 8 Store App Crash Logs

  - by David Paquette

  I was recently working on a Windows 8 app, and the application was crashing occasionally.  When resuming the application, the app would crash and close immediately without providing any feedback or information on what went wrong.  The crash was very difficult to reproduce, and I could never get the crash to occur when I was debugging through Visual Studio.  My app was crashing, and I had no idea what was going wrong!  HELP!!! After doing some digging, I found that when a Windows 8 Store App crashes, an error is logged in Windows Administrative Events.  You can view the details of any app crash by launching the Event Viewer and selecting Administrative Events under Custom Views.  The Source of the error will be listed as AppHost.  AppHost is the process that runs your Windows 8 Store App.  The error details contain all the information you would expect to find, including a stack trace and line numbers.   Windows 8 Tip:  A shortcut for launching the Event Viewer in Windows 8.  Right click on the bottom left corner of your desktop (where you normally click to go to the Start Screen).  A menu will appear with shortcuts to a number of common system tasks such as Event Viewer, Task Manager, Command Prompt, and Device Manager.

• Why would my mouse pointer be jerky when it can't get a signal from my router?

  - by izb

  I've got a fairly new PC but when moving the mouse across the screen, the pointer jerks as if the PC is freezing momentarily every second or so. Strangely, this only seems to happen if the signal from the wifi router is bad. If I move the PC closer to the router to get a full signal, it's fine. It also seems to affect the keyboard; Opening notepad and holding down a key shows the same momentary freezes. -- Update: It's a logitech wireless mouse, and a wired USB logitech keyboard.

• Hyper-V Guests suddenly stopped working

  - by Anton Gogolev

  Hi! Here's my configuration: Windows Server 2008 R2 Standard as a host OS, and two guests VMs running the same exact OS. Yesterday, Trial Activation on all OSes has expired and quite naturally all machines shut down. I rearmed the host, but cannot log on to either guest VMs. From what I see, they start up normally (State is listed as Running) but CPU Usage seems to be stuck at 3% and when I connect to it all I see is black textmode screen with cursor blinking. One of my VMs has several snapshots, and when I revert back, it starts up normally. Moreover, "reference VM" (the one I cloned these two VMs from) starts up just normally. How can I troubleshoot this issue?

• Install wireless router with cable modem - need authentication server?

  - by Paul

  I've bought a wireless router which I'm installing with a Telstra BigPond cable modem for a friend. As part of the setup I've got to a screen requesting username / password / authentication server for the cable modem They have contacted Telstra who supply the username / password and say that is all they need. They dont know anything about an authentication server. There are a couple of answers up on Whirlpool forum found through google but those answers are 4 years old. http://forums.whirlpool.net.au/forum-replies-archive.cfm/475258.html http://forums.whirlpool.net.au/forum-replies-archive.cfm/479615.html I havent tried them yet as I hoped to get actual answers before trundling over to my friends house again. Can anyone suggest, How to get information from Telstra support? (I realise this question maybe impossible to answer) What is the authentication server for Telstra BigPond for a user in Sydney Australia Are those whirlpool forum answers still valid? I guess if I dont get anything more here I'll try what it says on whirlpool and see what happens.

• Create intentional border with xrandr

  - by benizi

  Is there a way to tell xrandr "this space intentionally left blank"? I have a laptop that drives its internal display at 1920x1080, but the external monitor I'm using, due to its different aspect ratio, doesn't have that mode. It runs at 1920x1200. So, the basic setup: xrandr \ --output LVDS-1 --mode 1920x1080 \ --output DP-1 --mode 1920x1200 --same-as LVDS-1 [not to scale:] +-----------------------------------+ ¦ ¦ ¦ ¦ (laptop) ¦ (external) ¦ ¦ (LVDS-1) ¦ (DP-1) ¦ ¦ ¦ ¦ ¦ ¦ ¦ +-----------------¦ ¦ (blank...) ¦ ¦ +-----------------+ How can I specify that the 1920x120-sized region below LVDS-1 should be displayed as a black bar that can't be accessed by mouse on DP-1? I tried just coping with --panning 1920x1200+0+0/1920x1080+0+0/0/0/0/120, but I found the screen movement to be very annoying. Update: I found a workaround. (Update 2: changed it to an answer, per suggestion -- workaround doesn't answer the underlying question of leaving space blank.)

• Windows 7 unresponsive after hibernate.

  - by Simon Verbeke

  The last few days, when I get Windows out of hibernate, Windows itself gets unresponsive. I can use any of my programs that were already opened before hibernating, but the window functions (closing, changing the size etc) aren't reacting. I can't open any new programs, except for the Task Manager. Also, I don't get an Internet connection. When I use Ctrl + Alt + Del, I get either a black screen, or the regular background. Then it hangs and after a while shows me a message that Windows failed starting up that "thing"(don't know what it's called in English, something with safety, etc). I have Windows 7 Ultimate installed.

• Fast determination of whether objects are onscreen in 2D

  - by Ben Ezard

  So currently, I have this in each object's renderer's update method: float a = transform.position.x * Main.scale; float b = transform.position.y * Main.scale; float c = Camera.main.transform.position.x * Main.scale; float d = Camera.main.transform.position.y * Main.scale; onscreen = a + width - c > 0 && a - c < GameView.width && b + height - d > 0 && b - d < GameView.height; transform.position is a 2D vector containing the game engine's definition of where the object is - this is then multiplied by Main.scale to translate that coordinate into actual screen space Similarly, Camera.main.transform.position is the in-engine representation of where the main camera is, and this is also multiplied by Main.scale The problem is, as my game is tile-based, thousands of these updates get called every frame, just to determine whether or not each object should be drawn - how can I improve this please?

• ProStar gaming laptop, which had Ubuntu 10.10, won't boot past Grub. Thoughts?

  - by Richard Zak

  At work we have some high-end gaming laptops we use for their dual GPUs. The machines have second generation i7 CPUs, and came with Windows 7. On most of them I installed Ubuntu 10.10, and all was fine. There were two laptops that I wanted to repurpose and wanted to reinstall the OS. It boots the CD (burned Ubuntu installation CD, I've tried 10.10, 11.10, and 12.04, as well as CentOS 6), and when Grub tried to boot the kernel, I just get a cursor blinking in the upper left corner of the screen. I tried the disabling of ACPI and the other items in the advanced menu, but nothing works. I could still boot to the current Linux installation though. I was able to install Windows 7 again, and use WUBI, but I think that works because it uses the Windows bootloader and not Grub. How could it have worked before and not now? I have confirmed that the CD is fine, as are the hard drive and CD drive. I also had the same problem with Debian, and had to boot through Windows 7 to install it.

• techniques for displaying vehicle damage

  - by norca

  I wonder how I can displaying vehicle damage. I am talking about an good way to show damage on screen. Witch kind of model are common in games and what are the benefits of them. What is state of the art? One way i can imagine is to save a set of textures (normal/color/lightmaps, etc) to a state of the car (normal, damage, burnt out) and switch or blending them. But is this really good without changing the model? Another way i was thinking about is preparing animations for different locations on my car, something like damage on the front, on the leftside/rightside or on the back. And start blending the specific animation. But is this working with good textures? Whats about physik engines? Is it usefull to use it for deforming vertexdata? i think losing parts of my car (doors, sirens, weapons) can looks really nice. my game is a kind of rts in a top down view. vehicles are not the really most importend units (its no racing game), but i have quite a lot in. thx for help

• Remove enemy when bullet hits enemy

  - by jordi12100

  For my education I have to make a basic game in HTML5 canvas. The game is a shooter game. When you can move left - right and space is shoot. When I shoot the bullets will move up. The enemy moves down. When the bullet hits the enemy the enemy has to dissapear and it will gain +1 score. But the enemy will dissapear after it comes up the screen. Demo: http://jordikroon.nl/test.html space = shoot + enemy shows up This is my code: for (i=0;i<enemyX.length;i++) { if(enemyX[i] > canvas.height) { enemyY.splice(i,1); enemyX.splice(i,1); } else { enemyY[i] += 5; moveEnemy(enemyX[i],enemyY[i]); } } for (i=0;i<bulletX.length;i++) { if(bulletY[i] < 0) { bulletY.splice(i,1); bulletX.splice(i,1); } else { bulletY[i] -= 5; moveBullet(bulletX[i],bulletY[i]); for (ib=0;ib<enemyX.length;ib++) { if(bulletX[i] + 50 < enemyX[ib] || enemyX[ib] + 50 < bulletX[i] || bulletY[i] + 50 < enemyY[ib] || enemyY[ib] + 50 < bulletY[i]) { ++score; enemyY.splice(i,1); enemyX.splice(i,1); } } } } Objects: function moveBullet(posX,posY) { //console.log(posY); ctx.arc(posX, (posY-150), 10, 0 , 2 * Math.PI, false); } function moveEnemy(posX,posY) { ctx.rect(posX, posY, 50, 50); ctx.fillStyle = '#ffffff'; ctx.fill(); }

• Testing of visualization projects

  - by paxRoman

  We develop small to large visualization projects for different tasks and industries and sometimes while rewriting them a couple of times in the process we hit walls because we discover that we need to add a lot of code to support new requirements. Now we have established a design process that seems to work well (at least we reduced the development time for each new project quite a bit), but we're still left scratching our heads around this question: what exactly should we test when testing visualizations? If everything that we want to explore is on the screen (bounded visualizations)? If the data is ok - if data is valid (that's one of the nice things about visualizations you can spot errors in your datasets)? Usability? User interaction? Code quality? I can tell you for sure that a simple check of the code quality is certainly not enough! Is there a classic paper / book about how to test visualizations? Also do you happen to know about classic design patterns for visualizations (except the obvious ones like Pub-Sub)?

• Nifty default controls prevent the rest of my game from rendering

  - by zergylord

  I've been trying to add a basic HUD to my 2D LWJGL game using nifty gui, and while I've been successful in rendering panels and static text on top of the game, using the built-in nifty controls (e.g. an editable text field) causes the rest of my game to not render. The strange part is that I don't even have to render the gui control, merely declaring it appears to cause this problem. I'm truly lost here, so even the vaguest glimmer of hope would be appreciated :-) Some code showing the basic layout of the problem: display setup: // load default styles nifty.loadStyleFile("nifty-default-styles.xml"); // load standard controls nifty.loadControlFile("nifty-default-controls.xml"); screen = new ScreenBuilder("start") {{ layer(new LayerBuilder("baseLayer") {{ childLayoutHorizontal(); //next line causes the problem control(new TextFieldBuilder("input","asdf") {{ width("200px"); }}); }}); }}.build(nifty); nifty.gotoScreen("start"); rendering glMatrixMode(GL_PROJECTION); glLoadIdentity(); GLU.gluOrtho2D(0f,WINDOW_DIMENSIONS[0],WINDOW_DIMENSIONS[1],0f); //I can remove the 2 nifty lines, and the game still won't render nifty.render(true); nifty.update(); glMatrixMode(GL_PROJECTION); glLoadIdentity(); GLU.gluOrtho2D(0f,(float)VIEWPORT_DIMENSIONS[0],0f,(float)VIEWPORT_DIMENSIONS[1]); glTranslatef(translation[0],translation[1],0); for (Bubble bubble:bubbles){ bubble.draw(); } for (Wall wall:walls){ wall.draw(); } for(Missile missile:missiles){ missile.draw(); } for(Mob mob:mobs){ mob.draw(); } agent.draw();

• Simple multi-seat

  - by Oli

  I've asked about multiseat before. The answer (for 10.04) involved doing it the proper way (eg through gdm, multiple server layouts). The problem was that gdm needs to be patched or reverted to 2.20 for multiseat. It's an ugly hack that, worse than anything, will hold up future updates. As a result, I didn't do anything. I still have a spare video card. I still have the monitor, keyboard and mouse all sitting waiting to jump into action. And I still want to be able to turn that into a simple desktop. My needs don't seem complicated. I have a second video card, a USB hub and anything connected to that USB hub that I want to be dedicated to another X server. I don't need a login screen (I'm happy hard-coding in a auto-login and I'd be happy with the user starting the X server if that's possible). This is so simple in my head that I only need two questions: How can I explicitly start an X server from the command line on an unused video adapter (by passing it whatever configuration I need to)? Can I have this new X session load a desktop environment on load? This seems like something you should be able to write in a little upstart script within 10 minutes. That would be perfect for me as then I'd have a nice start/stop control over the secondary desktop from the main desktop (that I want to leave unscathed!) I'm thinking something as simple as this for the payload: su -u other_user -c "startx -- localhost hardware-information" And use .xinitrc to load openbox or something...
