• 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.

• How come Win+R prompt can open Python when it's not in my path?

  - by houbysoft

  When I use the run prompt in Windows XP Professional (Win+R), and type python.exe or python, it works and greets me with the python prompt. However, when I start a cmd window, and then type python.exe or python, it doesn't find it. This is what I expect, as the Python directory (for me, I:\Python31\) is not in my PATH. How come, then, that if I type python.exe in the Win+R prompt, it works? Edit: here is a partial output of SET, I removed most irrelevant entries, I'm not sure why is it useful, apart from the PATH variable which I already said doesn't include the Python directory. If you need a particular variable other than these, please ask. CLIENTNAME=Console CommonProgramFiles=I:\Program Files\Common Files ComSpec=I:\WINDOWS\system32\cmd.exe FP_NO_HOST_CHECK=NO OS=Windows_NT Path=I:\WINDOWS\system32;I:\WINDOWS;I:\WINDOWS\system32\WBEM;I:\WINDOWS\system32\WindowsPowerShell\v1.0;I:\Qt\2010.05\mingw\bin;I:\Program Files\CMake 2.8\bin PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.PSC1 ProgramFiles=I:\Program Files PROMPT=$P$G SESSIONNAME=Console SystemDrive=I: SystemRoot=I:\WINDOWS VBOX_INSTALL_PATH=I:\Program Files\Oracle\VirtualBox\ windir=I:\WINDOWS

• Home and End keys in Emacs don't work when run from Tmux

  - by Jan Stolarek

  When I run Emacs from Tmux, the Home and End keys do not work (Home key runs the Search command as if C-s was pressed). The problem started when I added this in my ~/.bashrc file: TERM="xterm" export TERM I've read somewhere that TERM variable should not be set manually but this was the only way I was able to solve problems with colors. Without this setting I got different colors in Emacs when running directly from the terminal and different when running from Tmux. This option caused some of the keys not to work in Emacs when it was run from Tmux, so I added this line to my ~/.tmux.conf: set-window-option -g xterm-keys on This solved problem with all keys except for Home and End. Any ideas how to make these keys work again?

• Why did the web win the space of remote applications and X not?

  - by Martin Josefsson

  The X Window System is 25 years old, it had it's birthday yesterday (on the 15'th). As you probably are aware of, one of it's most important features is the separation of the server side and the client side in a way that neither Microsoft's, Apples or Wayland's windowing systems have. Back in the days (sorry for the ambiguous phrasing) many believed X would dominate over other ways to make windows because of this separation of server and client, allowing the application to be ran on a server somewhere else while the user clicks and types on her own computer at home. This use obviously still exists, but is marginalized at best. When we write and use programs that run on a server we almost always use the web with it's html/css/js. Why did the web win, and X not? The technologies used for the web (said html/css/js) are a mess. Combined with all the back-end-frameworks (Rails, Django and all) it really is a jungle to navigate thru. Still the web thrives with creativity and progress, while remote X apps do not.

• Unable to install Android for Windows 7 because JDK is not found

  - by user1294663

  I have JDK SE7u4 installed in windows 7. I tried to install Android on Windows 7 using the installer_r18-windows.exe but no avail. The setup window showed the message saying that the Java SE JDK not found and ERROR: Failed to find Java version for C:\Windows\System32\java.exe The system cannot found the file specified. If you believe you have a JDK installed and it was not properly recognized, simply set an environment variable JAVA_HOME to point to it I right clicked on Computer Properties Advanced System Settings Environment variables. I created a NEW system variable called JAVA_HOME and set the value as C:\Program Files\Java\jdk1.7.0_04\bin or C:\Windows\System32\java.exe. I ran the installer again — the same error message still appeared.

• Who can change the View in MVC?

  - by Luke

  I'm working on a thick client graph displaying and manipulation application. I'm trying to apply the MVC pattern to our 3D visualization component. Here is what I have for the Model, View, and Controller: Model - The graph and it's metadata. This includes vertices, edges, and the attributes of each. It does not contain position information, icons, colors, or anything display related. View - This would commonly be called a scene graph. It includes the 3D display information, texture information, color information, and anything else that is related specifically to the visualization of the model. Controller - The controller takes the view and displays it in a Window using OpenGL (but it could potentially be any 3D graphics package). The application has various "layouts" that change the position of the vertices in the display. For instance, one layout may arrange the vertices in a circle. Is it common for these layouts to access and change the view directly? Should they go through the Controller to access the View? If they go through the Controller, should they just ask for direct access to the View or should each change go through the controller? I realize this is a bit different from the standard MVC example where there a finite number of Views. In this case, the View can change in an infinite number of ways. Perhaps I'm shattering some basic principle of MVC here. Thanks in advance!

• Copy contents of a folder, but none of its subfolders?

  - by wizlog

  I'm using the explorer bar (the bar to the left of the main folder/files section in an explorer window) to show folders. I don't have access to open any of the folders, themselves (at least none on C:\ (the C drive). For some reason, I do however have copy rights (I can copy the folders). Because I can only see the folders, is there a way for me to copy the main folder, but not any of the subfolders? A localized example could be how to copy all files in C:\documents...[user]\my documetns\ but none of the folders (ex. C:\documents...[user]\my documetns\my pictures...) Is there a way for me only to copy a folder, but not its subfolders?

• 3d Model Scaling With Camera

  - by spasarto

  I have a very simple 3D maze program that uses a first person camera to navigate the maze. I'm trying to scale the blocks that make up the maze walls and floor so the corridors seem more roomy to the camera. Every time I scale the model, the camera seems to scale with it, and the corridors always stay the same width. I've tried apply the scale to the model in the content pipe (setting the scale property of the model in the properties window in VS). I've also tried to apply the scale using Matrix.CreateScale(float) using the Scale-Rotate-Transform order with the same result. If I leave the camera speed the same, the camera moves slower, so I know it's traversing a larger distance, but the world doesn't look larger; the camera just seems slower. I'm not sure what part of the code to include since I don't know if it is an issue with my model, camera, or something else. Any hints at what I'm doing wrong? Camera: Projection = Matrix.CreatePerspectiveFieldOfView( MathHelper.PiOver4, _device.Viewport.AspectRatio, 1.0f, 1000.0f ); Matrix camRotMatrix = Matrix.CreateRotationX( _cameraPitch ) * Matrix.CreateRotationY( _cameraYaw ); Vector3 transCamRef = Vector3.Transform( _cameraForward, camRotMatrix ); _cameraTarget = transCamRef + CameraPosition; Vector3 camRotUpVector = Vector3.Transform( _cameraUpVector, camRotMatrix ); View = Matrix.CreateLookAt( CameraPosition, _cameraTarget, camRotUpVector ); Model: World = Matrix.CreateTranslation( Position );

• Why are applications slowing down on the computer's second monitor?

  - by ChristianLinnell

  Here's an interesting one. Problem I have a user on Windows XP who is running a web application inside IE8. She has two monitors plugged in via DVI cables. When she is working the the browser on her primary monitor, everything is fine, but when she drags the window over to the second monitor, the web applications functionality grinds to a halt. It's not just web apps either - many applications exhibit the problem. What I've tried Switching the two monitors in the OS. It's obviously not the monitor's fault. Confirmed that it's the app slowing down, and not the graphical rendering. The application in question actually locks up. The mouse is unaffected, and I can drag other windows on top of the problematic application. Any ideas?

• How can I keep gnu screen from becoming unresponsive after losing my SSH connection?

  - by Mikey

  I use a VPN tunnel to connect to my work network and then SSH to connect to my work PC running cygwin. Once logged in I can attach to a screen session and everything works great. Now, after a while, I walk away from my computer and sooner or later, the VPN tunnel times out. The SSH connection on each end eventually times out and then I eventually come back to my computer to do some work. Theoretically, this should be a simple matter of just restarting the VPN, reconnecting via SSH, and then running "screen -r -d". However apparently when the sshd daemon times out on the cygwin PC, it leaves the screen session in some kind of hung state. I can reproduce a similar hung state by clicking the close box on a cygwin bash shell window while it's running a screen session. Is there any way to get the screen session to recover once this has happened, so that I don't lose anything?

• A software to lock regions of a screen to prevent any windows from overlapping

  - by cybervaldez

  I've just installed nexus dock (a similar application like rocketdock), after playing with the preferences i've come across a very curious option (under position & behavior) that says: Prevent maximized windows from overlapping the dock. With it enabled, any application I maximize(and i do mean any) won't overlap the dock, it's really great. So i'm thinking perhaps there's a software that does this kind of feature which is really ideal for keeping my workspace really organized. I really hate repositioning and resizing my windows everytime. Of course there's always the manual way of doing these but it's just too much of a bother when someone from the family uses the computer. Do you know any software that does this? even a software that can just save/remember window positions would also be nice too.

• Firefox, Thunderbird, Safari - hangs up on start

  - by takeshin

  I have a strange problem on Windows Vista (Automatic updates). Long time ago I had installed Firefox, Thunderbird, Safari and Opera and they all worked well. Once upon a time, after Windows restart, Firefox, Thunderbird and Safari won't start. [Opera (USB) works fine]. When I start the browser, program name is listed on the processes list, but it is not activated, doesn't show any window. I tried crating new profiles with -ProfileManager, restarting Windows, reinstalling the browsers. I scanned the system for suspected programs and it looks clean. There is 45GB of free HDD space. WTF?

• pymatplotlib without xserver

  Is it possible to use networkx or pymatplotlib without an xserver running?

• On Windows 7, how do I fix my cmd.exe icon and remove cruft from the jumplist

  - by sb3700

  Hi. When installing drivers for my Gigabyte motherboard, I installed a "Games" link which ran from a batch file. This was pinned to the taskbar by default. As a result, it changed the icon for cmd.exe to the icon for Games. I uninstalled the Games and it got rid of the icon leaving it with a white rectangle thing (I can post screenshots on request). There is also a link on the jumplist to open Games, which just opens a cmd window. I've tried rebuilding my icon cache as per Changing Windows 7 pinned taskbar icons, but this only removed the white rectangle icon, leaving me with no real icon. c:\windows\system32\cmd.exe still has the appropriate icon in explorer, just not on the taskbar. Any ideas on how to fix this annoyance?

• rdesktop + seamlessrdp + virtualbox slow on Windows

  - by Claudiu

  I'm trying to get VirtualBox seamless mode to work on all of my monitors at once. I was directed to this link, so I followed the instructions, using the windows port of rdesktop 1.6 found here, and using Xming as an X server. I eventually finally got it to work! However, it's really slow. While VirtualBox's regular seamless mode is as performant as if I was running apps on my host machine, with rdesktop it takes 1-2 seconds to register any user input. Dragging windows around is laggy and buggy (pieces of the desktop behind the window show through). I'm simply connecting to localhost, so network bandwidth/latency shouldn't be an issue... anyone have any idea why it's so slow and what I can do to make it more performant?

• Is there an application that can automatically set Graphics Properties when docking?

  - by Ken Liu

  I have a dual display setup with my laptop (Dell, with integrated graphics, WinXP). The problem is that whenever I hook up the laptop to the monitor I have to go to Graphics Properties (Intel Graphics Media Driver for Mobile) and set the display resolution, window position, etc. Note that this screen is different than the built-in one you usually see in WinXP. 1) Is there an app that can save display settings properly so they will come back when I dock again? 2) Barring this, run a script or a macro to automatically set up the display the way I want it. 3) Or, can I write a .Net program that does this for me? Extra points if there is an Open source app that can do this.

• bridge to share WiFi internet connection over eth0

  - by rubo77

  In this script there is implemented that you create a mesh network and connect other machines to your device to serve an internet connection with dhcp: echo "starting bridge to share internet connection over eth0" ifconfig eth0 up promisc brctl addbr br-freifunk brctl addif br-freifunk bat0 brctl addif br-freifunk eth0 echo "internet starting, this may take some minutes due to latency..." echo "(use" echo "tail -f /var/log/syslog" echo "in another window for debugging)" echo echo dhclient br-freifunk echo "The error 'Rather than invoking init scripts through /etc/init.d...' can be ignored:" dhclient br-freifunk # without bridge: dhclient bat0 This works fine with the freifunk-mesh network. But how can I serve internet in a normal case? I would like to connect to any open Wifi I find with my network-manager or wicd (yes, with the graphical GUI) and then start a small script that creates a bridge to my network-out on my laptop I use Ubuntu and my networkcards are eth0 and wlan0

• Script errors when run by launchd at startup, but not when run in Terminal

  - by Mechcozmo

  I'm attempting to create a RAM disk that loads the previous contents when the system starts up, and every six hours writes the contents to a disk image. Currently, when you run the script from the terminal ("sudo bash LogToRAM.sh") everything works fine. But when run from launchd during startup, it doesn't work. Here's the lines from the log; the first line just gives some idea as to where in the boot process we are: SecurityAgent[202] Showing Login Window com.mechcozmo.LogToRAM[51] + /Developer/usr/bin/SetFile -a V /Volumes/LogfileRAMdisk com.mechcozmo.LogToRAM[51] ERROR: File Not Found. (-43) on file: /Volumes/LogfileRAMdisk com.mechcozmo.LogToRAM[51] + /usr/sbin/asr -source '/Library/Application Support/LogToRAM/RAMdisk_store.dmg' -target /Volumes/LogfileRAMdisk/ -noverify Here is the script and plist file in question. Note that 'set -vx' is up at the top of the script; it give a lot of information about what is happening in the script. My current theory is that the /Volumes directory does not exist at this stage of the boot process, but that seems unlikely to be honest.

• Adobe Reader - Content Preparation progress

  - by kubal5003

  Hello, I was wondering recently if is it just me or anyone else noticed it: why Adobe Reader after opening every single document displays "Content preparation" window with progress bar and it lasts for ages.. ? On linux pdf readers work hell lot better (faster), on windows other readers also work faster. Some years back in the past Adobe Reader also used to be quick. What has happened? PDF files aren't bigger/more complex compared to 3-4 years ago. Computers are at least dual core and with much more ram and displaying pdf files is getting slower and slower..

• What's wrong with my MAC address?

  - by Shaul

  I have a D-Link DSL-2650U router, and exactly one computer on the network. For reasons of port forwarding I want to give my computer a static internal IP address, so that I don't take the chance of losing my NAT settings every time the computer reboots. So here's a screen shot that summarizes the entire problem: WTH is wrong with my MAC address? It's copied and pasted from the command prompt window! I tried editing out the dashes, but it still doesn't work. Am I doing something wrong, or is there a bug in the D-Link firmware?

• I can't enable extra effects in Ubuntu 10.10. Please help?

  - by jasoncruz98

  I installed Ubuntu 10.10 alongside Ubuntu 11.10 to use an older version of Compiz. On Ubuntu 11.10, Compiz was enabled by default and I didn't need to use any graphics driver to enjoy the effects. All I had to do was install CompizConfig Settings Manager and enable those extra effects. That was Compiz 0.9.6. Now, after installing Ubuntu 10.10, when I first logged in, the graphics were slow. When I dragged a window from one end of the screen to the other, the whole screen would blur up and pixelate and it would be very laggy. I tried going to System Preference Appearance and selecting Extra effects on the Visual effects tab, but all I got was "Desktop effects could not be enabled". I don't know whether I should install the Additional drivers (proprietary) because my Internet is slow and it would take a long time. Furthermore, in Ubuntu 11.10, after I installed the proprietary graphics driver, I immediately went into fallback mode and wasn't even offered an option to set my desktop session to Ubuntu 3D. I didn't need the driver to run Compiz in Ubuntu 11.10, it just ran so smoothly. But in Ubuntu 10.10, everything is so laggy. Should I install the ATI/AMD Proprietary FGLRX Graphics Driver for Ubuntu 10.10 to enable extra effects? Or is there something else wrong with my system? Here is the output of lspci -nn | grep VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation Sandy Bridge Integrated Graphics Controller [8086:0116] (rev 09) 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Device [1002:6760] Here is the output of the same command, but in Ubuntu 11.10 (in this case the one which is correct, because I don't have the Sandy Bridge Integrated graphics controller) 00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc NI Seymour [AMD Radeon HD 6470M] [1002:6760]

• How to make fonts smooth and readable in Debian/Ubuntu?

  - by jmdeldin

  What is the best, most foolproof way of getting nice font rendering in Linux? Currently, I am experiencing thin, ugly fonts (shown below). I have wasted too much time tweaking fonts.conf, and I have yet to find a decent combination. I am running Debian 6.0 with no desktop environment (just Openbox for a window manager) in a VM on a Macbook Pro (OS X 10.7.4). Screenshots The following screenshots were taken without fonts.conf and .Xdefaults tweaks. running in "native" Openbox environment: http://i.imgur.com/10bnH.png running over X11, which looks a little worse than Openbox: http://i.imgur.com/sq8jk.png Thank you!

• backing up ntfs disk using rsync on ubuntu

  - by user70366

  For a long time I was using windows. I have a separate drive I use to keep copies of my media files, photos etc. on, which I periodically backup to an external drive. In Windows I used SyncToy to do this. After my Windows stopped booting, I decided to switch to Linux (Ubuntu 10.10). That seems to be going fine, but now I want to backup my drive to the external drive like before. Mostly the two drives will be already the same with maybe about 10GB of extra files added. So I try to use rsync to synchronise the two drives like this: rsync --dry-run -rvlt --modify-window=1 /media/Antonio1TB/Backup /media/FREECOM\ HDD/Backup The problem is the dry run indicates that every file on the drive will be copied. Not just the files I have recently added. What is the correct command to synch two NTFS drives under Ubuntu so that files that already exist don't get copied again? Thanks.
