  • Can you help diagnose why this laptop running ubantu has crashed and seemingly died

    - by krhodes
    Love any suggestions you have to this problem. My laptop had Window Vista on previously (sorry). Something went wrong, I can't remember, and I tried to reinstall but couldn't, installed a replacement second hand HD, and installed Ubantu instead. It worked ok for a little while, before crashing. I ended up reloading Ubantu three times. It works for a while after (say 3-5 hrs of domestic web browsing), and then crashes. When I turn it on now, it comes up with some options to restart in safe mode, run tests and so on. I can't get it to start normally. I'm not going to re-install again. Below are screen shots of what happens when I follow some of these test options. These screen shots mean nothing to me. Any ideas? Surely I can fix this.... http://i1219.photobucket.com/albums/dd434/keithrhodes1/P1050109.jpg http://i1219.photobucket.com/albums/dd434/keithrhodes1/P1050105.jpg Thanks in advance for any suggestions Keith

  • Windows 7: This notification icon is currently not active

    - by icelava
    Some time this week, without any major change done to one of my x64 Windows 7 computers, the Media eject icon goes missing in the systray taskbar area. When I attempt to reset the notification settings, i see this "This notification icon is currently not active" info warning Initially KB945011 managed to restore the icon after a reboot. But now it appears to have disappeared again. It seems to have disappeared (cannot really confirm) after I unlock the physical logon session (which was previously rerouted to a virtual Remote Desktop session). Anybody have knowledge on possible causes to this missing behaviour? UPDATE 1 Feb 11 It seems that happens often when I remote desktop to the computer, I see it from the remote screen, but when i unlock the screen physically, it disappears. It would reappear when I connect to remote desktop again. Hmmmmm.

  • Including Microsoft.XNA.Framework.Input.Touch in a project?

    - by steven_desu
    So after running through tutorials by both Microsoft and www.xnadevelopment.com I feel very confident in my ability to get to work on my first game using the XNA Framework. I've manipulated sprites, added audio, changed game states, and even went a step further to apply the knowledge I had and figure out how to make animations and basic 2-dimensional physics (including impulses, force, acceleration, and speed calculations) But then shortly into the project I hit a curious bump that I've been unable to figure out. In wanting to implement menus, pause screens, and several different aspects of play (a "pre-level" prep screen, the level itself, and a screen after the level to review how well you did) I took a look at Microsoft's Game State Management sample. I understood the concept, although it was admittedly quite a lot to take in. Not wanting to recreate the entire concept by scratch (after all- what purpose would that serve?) I tried copying and pasting the sample code into my own ScreenManager class (as well as InputState and GameScreen classes) to try and borrow their ingenuity. When I did this, however, my project stopped compiling. I was getting the following error: The type or namespace name 'Touch' does not exist in the namespace 'Microsoft.Xna.Framework.Input' (are you missing an assembly reference?) Having read through their sample code already, I realized that this namespace and every function and class within it could be safely ripped from the code without losing functionality. It's a namespace simply for integrating with touchscreen devices (presumably Windows Phone 7, but maybe also tablets). But then I began to wonder- how come Microsoft's sample compiled but mine didn't? I copied their code exactly so there must be a setting somewhere that I need to change in Visual Studio in order to correct this. I tried creating a new project as a Windows Phone 7 game rather than a Windows game, however that only forced it to compile to a Windows Phone emulator and denied me the ability to change the resolution and other features which I clearly had the power to do in the sample code. So my question is simple - how do I properly use the namespace Microsoft.XNA.Framework.Input.Touch?

  • Can I remotely monitor printf results of a C program?

    - by Mota
    I have a long running C program in which I've started from the Terminal.app using: gdb program_name gdb run I'm using many printf statements to monitor the progress of the program. Unfortunately, the screen of the computer has been frozen since yesterday, but the process is still running. My question is, can I watch the progress of the program (i.e. the results of the printf statements) remotely? I'm not that familiar with the terminal, but I know how to ssh and do some simple terminal tasks. The OS of the machine with the frozen screen is Mac OS 10.6.

  • Windows 7 does not 'wake up' from Sleep mode

    - by the watchmaker
    I'm new to Windows 7, so I don't know if this is normal. When the computer is idle for 30 minutes, the screen goes black and no key pressing or mouse movement will bring the computer out of standby. The computer is still running (fans and hard drive noise) but it will not respond and the screen remains black. The only way to get a response is to press and hold the power button until it goes off, then switch it back on. When it turns on it says "Resuming Windows" and then goes black again. Is this normal? Can the time-out delay be increased? Is there a better workaround than switching the PC on and off?

  • HTML5 Canvas Converting between cartesian and isometric coordinates

    - by Amir
    I'm having issues wrapping my head around the Cartesian to Isometric coordinate conversion in HTML5 canvas. As I understand it, the process is two fold: (1) Scale down the y-axis by 0.5, i.e. ctx.scale(1,0.5); or ctx.setTransform(1,0,0,0.5,0,0); This supposedly produces the following matrix: [x; y] x [1, 0; 0, 0.5] (2) Rotate the context by 45 degrees, i.e. ctx.rotate(Math.PI/4); This should produce the following matrix: [x; y] x [cos(45), -sin(45); sin(45), cos(45)] This (somehow) results in the final matrix of ctx.setTransform(2,-1,1,0.5,0,0); which I cannot seem to understand... How is this matrix derived? I cannot seem to produce this matrix by multiplying the scaling and rotation matrices produced earlier... Also, if I write out the equation for the final transformation matrix, I get: newX = 2x + y newY = -x + y/2 But this doesn't seem to be correct. For example, the following code draws an isometric tile at cartesian coordinates (500, 100). ctx.setTransform(2,-1,1,0.5,0,0); ctx.fillRect(500, 100, width*2, height); When I check the result on the screen, the actual coordinates are (285, 215) which do not satisfy the equations I produced earlier... So what is going on here? I would be very grateful if you could: (1) Help me understand how the final isometric transformation matrix is derived; (2) Help me produce the correct equation for finding the on-screen coordinates of an isometric projection. Many thanks and kind regards

  • HTG Explains: How Internet Explorer Saves Your Passwords and How to Manage Them

    - by Taylor Gibb
    Privacy is very important when it comes to the digital world, but do you know exactly how your browser saves your passwords ? Read on to find out what goes on behind the scenes. When it comes to web applications, there are many different types of authentication. One of the types is called basic authentication, which is when you navigate to website and a dialog box opens to ask for a username and password. This also happens to be the authentication mechanism defined in the RFC for HTTP. You can see in the screen shot above that there is a check box that you can use to remember your credentials, but what does that do ? You might also ask yourself what happens if you are not using Basic authentication. There is another type of authentication called Form authentication, this is when the authentication is built right into the web application, like the How-To Geek website. This allows the Developer to control the look and feel of the form that we use to log in.

  • I can't get grub menu to show up during boot

    - by wim
    After trying (and failing) to install better ATI drivers in 11.10, I've somehow lost my grub menu at boot time. The screen does change to the familiar purple colour, but instead of a list of boot options it's just blank solid colour, and then disappears quickly and boots into the default entry normally. How can I get the bootloader back? I've tried sudo update-grub and also various different combinations of resolutions and colour depths in startupmanager application with no success (640x480, 1024x768, 1600x1200, 16 bits, 8 bits, 10 second delay, 7 second delay, 2 second delay...) edit: I have already tried holding down Shift during bootup and it does not seem to change the behaviour. I get the message "GRUB Loading" in the terminal, but then the place where the grub menu normally appears I get a solid blank magenta screen for a while. Here are the contents of /etc/default/grub # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=" vga=798 splash" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"

  • How do I debug xorg/fglrx related system freezes on Ubuntu 12.10?

    - by racerror
    My brand new system is randomly freezing and I don't know how to debug the issue. System: AMD A10-5800k Asus F2A85-M motherboard Integrated Radeon HD 7660D 8gb Samsung ddr3 1600 Ubuntu 12.10 Gnome shell / Unity (issue exists in both) xorg.conf (relevant parts): Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:0:1:0" Option "TexturedVideoSync" "on" Option "UseFastTLS" "2" EndSection Section "Screen" Identifier "aticonfig-Screen[0]-0" Device "aticonfig-Device[0]-0" Monitor "Monitor0" DefaultDepth 24 Option "UseEDID" "False" Option "ExactModeTimingsDVI" "True" Option "NoBandWidthTest" "true" Option "ModeValidation" "AllowNon60hzmodesDFPModes, NoEDIDDFPMaxSizeCheck, NoVertRefreshCheck, NoHorizSyncCheck, NoDFPNativeResolutionCheck, NoMaxSizeCheck, NoMaxPClkCheck, NoEDIDModes" Option "UseEDIDDPI" "False" Option "UseEDIDFreqs" "0" Option "NoLogo" "True" Option "Coolbits" "1" Option "metamodes" "DFP-0: 2560x1440_60 +0+0" SubSection "Display" Depth 24 Modes "2560x1440" EndSubSection I ran memtest on my ram and it checks out fine. I have tried using the latest fglrx and fglrx-beta. I have loaded 3.6.x kernel. I do not see anything relevant in dmesg, kern.log, syslog, .xsession-errors or Xorg.log. I cannot ssh into the machine when frozen from another machine. I know that system resources not being stressed when the crashes happen. It seems that video and any gaming (very simple graphics games) contribute to the freezes most frequently. However, I have experienced the crash before when just using Chrome. I suspect the crashes are xorg/fglrx related, but I have no evidence to back that up. Where should I look? What should I grep for? What should I try next?

  • Hide Win 8.1 "tip" about "Switch between apps"?

    - by Carl R
    I've just installed Win8.1 and I'm trying to set up IIS. When I open Add remove programs from the start menu I get the pc-settings app. In the pc-settings app I get a "tooltip" or whatever we should call it, that hints me to "Switch between apps" by swiping from the edge. Well fine, but I don't want to do that right now, and I can't get that tip to dissapear. The tip lingers on even into Visual Studio, covering my code. I can't swipe because I don't have a touch screen, and also I'm on a multimonitor system that shows this tip in the middle of the screen. Here's a screenshot for you, where I put the web browser slightly over the left monitor. So, besides rebooting, how am I supposed to kill this very informative tip? EDIT When I kill the app by alt-f4 it dissapears right until I open the settings app again, then it's back. What I'm asking about is how to dismiss items like this in general.

  • Animated HTTP request visualisation on Apache

    - by Simon Bennett
    This is more a question to appease my memory in trying to remember what it was I saw a while ago. I remember being introduced to a realtime server visualisation tool that showed the current requests that Apache was handling in a kind of fireworks effect on screen. Each request/group of requests would be shot across the screen in varying colours. I can't for the life for me remember what is was called and hunting around here and Google has left me empty handed. Just wondering if anybody else was able to plug this gem from the memory and ease my pain! Thanks

  • Collision with half of a semi-circle

    - by heitortsergent
    I am trying to port a game I made using Flash/AS3, to the Windows Phone using C#/XNA 4.0. You can see it here: http://goo.gl/gzFiE In the flash version I used a pixel-perfect collision between meteors (it's a rectangle, and usually rotated) that spawn outside the screen, and move towards the center, and a shield in the center of the screen(which is half of a semi-circle, also rotated by the player), which made the meteor bounce back in the opposite direction it came from, when they collided. My goal now is to make the meteors bounce in different angles, depending on the position it collides with the shield (much like Pong, hitting the borders causes a change in the ball's angle). So, these are the 3 options I thought of: Pixel-perfect collision (Microsoft has a sample) , but then I wouldn't know how to change the meteor angle after the collision 3 BoundingCircle's to represent the half semi-circle shield, but then I would have to somehow move them as I rotate the shield. Farseer Physics. I could make a shape composed of 3 lines, and use that as the collision object for the shield. Is there any other way besides those? Which would be the best way to do it(it's aimed towards mobile devices, so pixel-perfect is probably not a good choice)? Most of the time there's always a easier/better way than what we think of...

  • How to revert to Eclipse's old behavior when double-clicking on frames or windows, in Juno?

    - by mattquiros
    I find Eclipse Juno very counter-intuitive. In my workspace, I used to just have the package view at the left, my code on the right, and whenever I'm printing something in the console, that's only when the console frame shows up from the bottom right. When you double click on a particular window, it either only goes fullscreen within Eclipse, or back to its original size together with the size of the other frames. In Juno, however, it seems that frames are put on layers on top of each other. When I print something to the console, the output frame only shows up as a small, useless square to my right. When I double-click, it goes full screen. When I double-click again, it occupies the full right frame, hiding my code. I double-click again and it goes full screen, then it double-clicks before it shares the right frame with my code on top of it. Then when I minimize it, it goes to the side. Any way to go back to the good old days of Eclipse? Thanks.

I have extracted the CD and started to change some parts of it, e.g Splash screen (splash.png) installer Title (through isolinux.cfg) etc These are the things that I want to do: Change the Splash logo at start up of installation to have my own (which is done) Change the grub boot parameters to use my comapny name on it. Change the set of packages in it, so that I can have my own set of packages in it and only those packages are installed Do some post installation steps Customize it's startup and login screen to have my company name. After I am done with this customization, I need to build its live installer CD so that I can install it on my own, on any other system.

  • Problem with SAT collision detection overlap checking code

    - by handyface
    I'm trying to implement a script that detects whether two rotated rectangles collide for my game, using SAT (Separating Axis Theorem). I used the method explained in the following article for my implementation in Google Dart. 2D Rotated Rectangle Collision I tried to implement this code into my game. Basically from what I understood was that I have two rectangles, these two rectangles can produce four axis (two per rectangle) by subtracting adjacent corner coordinates. Then all the corners from both rectangles need to be projected onto each axis, then multiplying the coordinates of the projection by the axis coordinates (point.x*axis.x+point.y*axis.y) to make a scalar value and checking whether the range of both the rectangle's projections overlap. When all the axis have overlapping projections, there's a collision. First of all, I'm wondering whether my comprehension about this algorithm is correct. If so I'd like to get some pointers in where my implementation (written in Dart, which is very readable for people comfortable with C-syntax) goes wrong. Thanks! EDIT: The question has been solved. For those interested in the working implementation: Click here

  • libGDX using Stage and Actor produces different camera angles on desktop and Android Phone

    libGDX using Stage and Actor produces different camera angles on desktop and Android Phone. Here are pictures demonstrating the problem: http://brandonyuh.minus.com/mFpdTSgN17VUq On the desktop version, the image takes up most all the screen.

  • Software for capturing still image snapshots from video input

    - by cantabilesoftware
    What software is available that will let me watch video from a USB video capture device at full PAL/NTSC resolution and capture a still image at a button press? More info: I'm using a KaiserBaas USB capture device (http://www.kaiserbaas.com/kaiser-baas-product-page/converters/video-to-dvd-maker), and want to capture screen shots from a PS2 connected to it. I'd like to play the game at the full PS2 resolution and capture certain scenes. The device has a one-touch snapshot button on it, but I can't seem to make it work and there's no mention of it anywhere in the documentation. The device works and the video appears in Power Producer (the included software), but I think it previews it smaller than the full resolution. I could print screen it, but having to crop will be a pain.

  • Why do I have no TTY on a basic Ubuntu 9.10 server install?

    - by pr1001
    I have reinstalled Ubuntu 9.10 Server several times on a bog standard 1RU server and each time I finish the install and reboot I see GRUB run and am then presented with a black screen. The machine is running just fine, as I am able to SSH in, but I can't see anything on the attached monitor. I have a simple LCD screen connected via VGA and a signal is apparently being output to it, as it doesn't go asleep. Looking at /var/log/syslog I see: Mar 24 14:57:44 bridge5 rsyslogd-2039: Could no open output file '/dev/xconsole' [try http://www.rsyslog.com/e/2039 ] However, I later see: Mar 24 14:57:44 bridge5 kernel: [ 0.001368] console [tty0] enabled Any thoughts?

  • Force shutdown a pc stuck in updating via Team Viewer

    Before I left office, I shutdown my work computer, leaving it in "Please do not power off..." screen. Now, when I log on to my own computer, I saw in Team Viewer that it's on. I thought it restarted instead of shutting down, but when I connect to it, it's still stuck in the previous screen. I've tried sending Ctrl-Alt-Del, but it seems to ignore it. I could still change its resolution via Team Viewer, and the fact that it respond my connection means it's not completely stalled. Is there anyway to shutdown it via Team Viewer?

  • How do I install the nvidia driver for a GeForce 9300M?

    - by Alex
    Yesterday i've installed ubuntu 11.04 (instead of 10.10). And i need to install nvidia driver which supports opengl 3.3 In 10.10 i did it in a such way: Ctrl+alt+f1 login sudo /etc/init.d/gdm stop sudo sh driver.run startx Not it doesn't work. Because ctrl+alt+f1 doesn't show login screen. Just only black screen. I've googled this problem. Some people have it but no one knows how to solve. Sometimes people say that it is connected with video card or driver. But i have GeForce 9300M G, and i've activated a standard driver. Anyway, it worked in 10.10, but doesn't work now. The main problem is that i need to kill xserver to install this driver. killing the process just only restarts xserver. Also, I've tried to /etc/init.d/gdm stop in GUI-console. It says that "Fake initctl,doing nothing". Google didn't helped in this case too. Any ideas to install that driver?

  • Gnome - windows always open top left

    - by BobTodd
    I find this a highly annoying "feature" on a wide screen monitor that my mostly used apps - terminal and gedit always open directly under the top-left corner of my screen and I have to drag them to my eye position each and every-time. I have tried installing the CompizConfig Settings Manager and using the feature to position windows centre, but this has had no effect - the force feature here isn't working for me either. I can use e.g. gnome-terminal --geometry=140x50+50+50 for the terminal but this doesn't work for gedit. Any ideas? Thanks
