• How to install nvidia drivers (GT 440 ) on Xubuntu 12.10 , screen res gone to 640x480 :(

  - by shaggyjack

  Hi all after days of endless googling I finally gave in and decided to try and directly ask for help. I have just installed Xubuntu and updated to 12.10 on a pretty old (12 years) machine, and I am now struggling to install the correct drivers for the nvidia 440 gt card.. I have managed to get "additional drivers" but the app does not show in the menu, I went through a few procedures which ended up in my screen going no higher than 640x480, and tried all the sudo apt-get variations with nvidia-current and current updates... I think I got the right version of the drivers ( 93.43.07 ) but they won't install from terminal as they say I am running an X server. So I learnt how to shut the graphic interface but then I try and install them from there but after I write the exact same command (sudo home/username/Downloads/NVIDIA-Linux-x86-96.43.07.pkg1.run ) nothing happens and the terminal says something like command not found. I am desperate for help if anybody could point me in the right direction that would be greatly appreciated. There are lots of similar topics on installing nvidia drivers but I seem to understand that current drivers are no good for my old GPU. So if anybody could show me how to install the right version that would be excellent. Thanks in advance! Jack

• Apple's Java Mac OS X 2012-006 Update

  - by Sharon Zakhour

  The recent Java Mac OS X 2012-006 update from Apple removes the Apple Java 6 plug-in from your Mac. The Mac OS X Install FAQ will be updated with the next 7u release, but you may find the following information useful in the meantime. Q: I have installed Java for OS X 2012-006 and Apple Java 6 can no longer be used for applets or Web Start. How do I get it back? A: The Java for OS X 2012-006 update from Apple uninstalls the Apple-provided Java applet plug-in from all web browsers. You can download the latest version of Java from Oracle, which has improved security, reliability and compatibility. If you prefer to continue using Apple's Java 6 plug-in, you can follow the steps provided in How to re-enable the Apple-provided Java SE 6 applet plug-in and Web Start functionality. Q: After installing Java for OS X 2012-006, can I continue to use Apple's Java 6 alongside the OS X JDK or JRE for Java 7? A: If you want to continue to develop with Java 6 in a Terminal window you can modify the startup script for your favorite command environment. For bash, use this: export JAVA_HOME=`/usr/libexec/java_home -v 1.6` Some applications use /usr/bin/java to invoke Java. After installing Java for OS X 2012-006, /usr/bin/java will find the newest JDK installed, and will use that for all of the Java related command line tools in /usr/bin. You may need to modify those applications to find Java 6, or contact the developer for a newer version of the application. Also, this update removes Apple provided Java Preferences app. For more information on how to determine the default version of Java on your system, see Determining the Installed Version of the JRE in the JRE 7 Installation for Mac OS X page.

• apxs cannot install mod_cloudflare on centos

  - by Adam

  [ Linux - CentOS - Apache 2.2 - mod_cloudflare - apxs2 ] I have changed my nameservers to point to CloudFlare. The problem is that all the IP addresses are coming in as CloudFlare's. This is no good, because I have to monitor and block some specific traffic. mod_cloudflare is supposed to resolve this but I have been unable to get this installed. The command in the documentation uses apxs2. I can't figure out how to install this, or if it just means for 'apache 2.4'. I'm running 2.2.3, and I can use 'apxs'. When I run: apxs -aic mod_cloudflare.c I get the error apxs:Error: Command failed with rc=65536 Does this mean I need apxs2 or something else? How do I get mod_cloudflare working on my server? I appreciate any help, the documentation is vague and limited.

• Kill Leaking Connections on SQL Server 2005

  - by Thierry Brunet

  We have a legacy ASP application that somewhere leaks SQL Connections. In Activity Monitor, I can see a bunch of idle processes with Last Batch times over an hour old. When I look at the T-SQL command batch, these are always FETCH API_CURSORXXX, which from my understanding is caused by improperly closed ASP ADO Recordsets. While we are try to pinpoint the offeding code, is there a way for me to monitor which requests open which cursors? I'm assuming profiler, but I'm not sure what I should be monitoring exactly. I can see a bunch of calls to sp_cursoropen but I don't see the API_CUSORXXX name anywhere. Second, would anyone be able to suggest a script we could run to kill these processes based on the Last Batch time 10 minutes and Last Batch Command being FETCH API_CURSORXXX? For various reasons, we unfortunately don't have any SQL Server DBAs.

• Conditional blocks of code in linux bash

  - by Arek

  Nearly everybody knows very useful && and || operators, for example: rm myf && echo "File is removed successfully" || echo "File is not removed" I've got a question: how to put a block of commands after && or || operators without using the function? For example I want to do: rm myf && \ echo "File is removed successfully" \ echo "another command executed when rm was successful" || \ echo "File is not removed" \ echo "another command executed when rm was NOT successful" What is the proper syntax of that script?

• How to install .deb file from within preinst script

  - by Ashwin D

  I have my own application packaged using dpkg. The application depends on several deb files which I'm trying to install from within the preinst script of my application. The preinst script checks if a dependent deb file is installed, if not it goes to installt it using the dpkg -i command. This is repeated for all the dependent deb files needed by the main application. When I try to install the main application using dpkg -i, the commands returns failure when trying to execute the preinst script. Below is that error message. dpkg: error: dpkg status database is locked by another process I deleted /var/lib/dpkg/lock file and retried to install the application. But to no avail. If I run the preinst script separately like any other shell script, it runs without any issue. All the deb files will be installed properly. So, the issue is only when this preinst script is being run automatically by the dpkg -i command. I'm lost trying to determine the root cause. If anyone can shed some light on what the real issue might be, their help will be greatly appreciated. Thank you. Ashwin

• adding remote ssh printer as local printer

  - by guest

  I have SSH access to a remote host (FreeBSD) that has a printer set up. I do not have root access on that host or any other special user rights. Now I want to print directly from my laptop on that printer (Ubuntu 10.10). The problem is that I don't know how to "import" or whatever the the printer, as it needs authetification from my user account (print quota limitations). E-mailing me the files I want to print or scp them every time is a pain, ATM I pipe the PostScript output manually to a ssh command, but that's also a huge working overhead. E.g. when I want to print a foo.pdf pdftops '/path/to/foo.pdf' - | ssh user@remotehost 'lpr -P printername' So, does anyone know of a smooth way to shorten this procedure? Ideally I would just want to use a printername instead of the whole ssh command

• Added autossh in rc.local, but the dynamic port forwarding won't work

  - by rankjie

  I am using Rasbian on my newly arrived Rasp.Pi, and decided to make it my own proxy server. Now I need to set up a ssh tunnel on the Pi to my Linode server, and make it auto start with the system. What did I do: Add this line to /etc/rc.local autossh -f theRemoteServer -N -D 5555 -L 1234:localhost:22 After I reboot, I found out that I can't use the localhost:5555 as a socks proxy. So I type the command ps -A | grep ssh then I can see the autossh and ssh all running: pi@raspberrypi ~ $ ps -A | grep ssh 2018 ? 00:00:00 sshd 2116 ? 00:00:00 autossh 2119 ? 00:00:00 sshd 2195 ? 00:00:00 sshd 3173 ? 00:00:00 ssh (I've installed autossh, and the command works if I type it manually.) (I use the passwordless key auth, so I don't have to enter password.) Much appreciated and sorry for my poor English.

• Create indefinitely oscillating pendulum in Farseer Physics 3.3.1/Box2d

  - by GONeale

  I am new to Farseer Physics and using version 3.3.1. I am after some help and would even be happy to receive Box2d answers just to ensure I get a response as I should then be able to convert it! -- Thanks ...After a lot of tinkering around I have managed to produce a thin vertical rectangle shape on the screen and I wish this to swing back and forth pinned at the top up to an angle I set (90 degrees would be fine for this sample). When it is approaching the top I wish it to slow down, then fall back the way it just came, increase speed then obviously slow to a stop at the top again. Almost how a swinging pirate ship would work at a theme park. This is the code I have so far which swings the shape, but it is seeming to lose speed on each swing eventually grinding to a halt: float playerWidth = ConvertUnits.ToSimUnits(5), playerHeight = ConvertUnits.ToSimUnits(68); playerPosition = ConvertUnits.ToSimUnits(-350, 0); playerBody = BodyFactory.CreateRectangle(World, playerWidth, playerHeight, 2f, playerPosition); playerBody.BodyType = BodyType.Dynamic; // create player sprite based on player body _rectangleSprite = new Sprite(ScreenManager.Assets.TextureFromShape(playerBody.FixtureList[0].Shape, MaterialType.Player, Color.Orange, 1f)); // Create swinging joint var joint = JointFactory.CreateFixedRevoluteJoint(World, playerBody, ConvertUnits.ToSimUnits(0, -34), playerBody.Position); If somebody could also provide the command I would need to pause the shape on a mouse click or keyboard command at it's current angle and then continue when I let go of the mouse click that would be super fantastic! (I actually posted this on StackOverflow as well before I realised there was a dedicated game development forum) Cheers

• Why is Thunar not creating and showing thumbnails of images?

  - by darenw

  Thunar is my main file manager. Normally it automatically creates thumbnail images of all images in the directory being viewed. After experimenting with other Linux distros then installing Arch Linux once and for all, Thunar is not showing thumbs. Image files all get the same generic image icon. Googling turned up some information: Something called gvfs needs to be installed. I have it. Still no go. (Apparently this isn't actually needed anyway.) Someone had this problem and fixed it by running some mime-related command (I didn't save any notes) I did this same command but no go. Checking the obvious: in Thunar's Edit/Preferences, yes, the [x] Show thumbnails is turned on. When I view one image in GIMP or EOG, the generic icon in Thunar is replaced by a thumbnail. But only for that one file I opened.

• Installing Ubuntu along with windows 7 on shrunk partition

  - by Thabo

  I am new to Ubuntu OS and ask Ubuntu community. First this is not a duplicate question. Actually this a question which is a summery of all solutions and questions were posted in this community, related to Install Ubuntu along with Windows 7. I have bought a new Hp laptop with its original windows 7.I want to install Ubuntu along with windows 7 64 bit. I ran the Ubuntu 12.4 Desktop installation CD. But Ubuntu installer doesn't show the "along with windows 7 option"only it is showing two options. I read some questions and answers posted on this community. Specially following link Ubuntu 12.04 does not see windows already install on my computer (dual installation) I tried following thinks, I ran the terminal in live CD and tried sudo dmraid -rE command and dmraid remove command .But terminals says there is no dmraid partitions. So I tried another scenario checked my partitions with g parted.There are some partitions labeled C,HP tools,Recovery and System. C is containing windows 7 Files. So I shrank the volume of C Drive. Now I have 50000Mb of unallocated disk. I tried with Gparted to create a partition on that allocated space.It says some thing that you can't create more than four primary partition.Of course all other four partitions were created on widows are actually type of primary partition. So I went back to Windows 7 and tried to create a new volume on unallocated space.But unfortunately it says,If i create a new volume it will be the type of Dynamic partition.It says we cant boot another OS from that partition. So i cancelled that step. Now i have 50000Mb unallocated space but how can i install Ubuntu on that partition without harming the existing Windows 7? Because still I have only two options: Erase and install Ubuntu. Try something else. (I can see my unallocated space by going to "something else" option.)

• Thread problem with XNA C#

  - by Luis

  I'm development a network card game, and for now i've two players connected but there is a problem with one of them, this one can't do anything on the game. Looks that screen was blocked. I'm think that is because a code i used before. That code is: if (InvokeRequired) { this.Invoke(new MethodInvoker(delegate { ... })); return; } The code above is surrounding code to changing Button values, make connection with server and create game window. Without this code a warning is shown. InvalidOperationException was unhandled Cross-thread operation not valid: Control 'startGameButton' accessed from a thread other than the thread it was created on.

• Is there a Windows 7 equivalent to the *NIX ability to create a hard link to /dev/null?

  - by minameismud

  I saw another question here that the Windows equivalent to /dev/null is simply NUL. I also know that you can use the mklink command to make sym links (shortcuts) from the command line: MKLINK [[/D] | [/H] | [/J]] Link Target /D Creates a directory symbolic link. Default is a file symbolic link. /H Creates a hard link instead of a symbolic link. /J Creates a Directory Junction. Link specifies the new symbolic link name. Target specifies the path (relative or absolute) that the new link refers to. When I try to use the /j switch to make a hard link ("junction") instead of a simple shortcut to NUL, I get: C:\>mklink /j "C:\Program Files\MyNewHardlinkFolder" NUL Local volumes are required to complete the operation. I can create shortcuts to NUL all day long using the /d switch, but I would much prefer the hard link. Any ideas?

• What is wrong with my expect script?

  - by Bryan

  I'm trying to learn how to use the expect command, to help me automate deployment of some software via shell scripts, and figured I start with something simple to get me started. I've created a file in my home dir called 'foo' using: touch foo And I've created the following script saved as test.exp #!/usr/bin/expect spawn rm -i foo expect "rm: remove regular empty file `foo'?" send "y\r" When I run the script using ./test.exp, it spawns the rm command, but it doesn't appear to send the Y and carriage return. I know I don't have a typo in the expect string, as I've used copy and paste to put in the script. What am I doing wrong?

• Linux Live CD for old computer

  - by Joel Coehoorn

  I have a pentium II (that's right, pentium II) with a scant 200MB of ram. This was a high-end workstation in it's day. The machine currently runs dos on a raid array, and I need to pull some data from it. I figure my best chance at this is to use a linux live cd to copy the data to one of our active directory network shares (there is a network card in the machine). Unfortunately, my linux skills are abysmal, so I'm not sure where to get started: Where should I look to find a linux cd that will run well on such an old system Since I'm likely gonna need to be command-line only, what do I need to do to configure the network card and mount the network share via the command line? Bonus points: exact syntax needed to copy and convert the entire volume for use in VMware server 2.0, but really just copying all the data should be enough.

• Changing DisplayMode seems not to update Input&Graphic Dimension

  - by coding.mof

  I'm writing a small game using Slick and Nifty-GUI. At the program startup I set the DisplayMode using the following lines: AppGameContainer app = new ... app.setDisplayMode( 800, 600, false ); app.start(); I wrote a Nifty-ScreenController for my settings dialog in which the user can select the desired DisplayMode. When I try to set the new DisplayMode within this controller class the game window gets resized correctly but the Graphics and Input objects aren't updated accordingly. Therefore my rendering code just uses a part of the new window. I tried to set different DisplayModes in the main method to test if it's generally possible to invoke this method multiple times. It seems that changing the DisplayMode only works before I call app.start(). Furthermore I tried to update the Graphics & Input object manually but the init and setDimensions methods are package private. :( Does someone know what I'm doing wrong and how to change the DisplayMode correctly?

• Procedure or function has too many arguments specified

  - by bullpit

  This error took me a while to figure out. I was using SqlDataSource with stored procedures for SELECT and UPDATE commands. The SELECT worked fine. Then I added UPDATE command and while trying to update, I would get this error: "Procedure of function has too many arguments specified" Apparently, good guys at .NET decided it is necessary to send SELECT parameters with the UPDATE command as well. So when I was sending the required parameters to the UPDATE sp, in reality, it was also getting my SELECT parameters, and thus failing. I had to add the extra parameters in the UPDATE stored procedure and make them NULLABLE so that they are not required....phew... Here is piece of SP with unused parameters. ALTER PROCEDURE [dbo].[UpdateMaintenanceRecord]        @RecordID INT     ,@District VARCHAR(255)     ,@Location VARCHAR(255)         --UNUSED PARAMETERS     ,@MTBillTo VARCHAR(255) = NULL     ,@SerialNumber VARCHAR(255) = NULL     ,@PartNumber VARCHAR(255) = NULL Update: I was getting that error because unkowingly, I had bound the extra fields in my GridVeiw with Bind() call. I changed all the extra one's, which did not need to be in Update, to Eval() and everything works fine.

• Increasing Screen Resolution to more than limit and scaling to origional

  - by Akshat Mittal

  I have a laptop, with Screen Resolution - 1366x768 (most common) - I want to increase it further to 1600x900 (or higher), in the same ratio. I want to scale the higher resolution on my current screen to fit it. I found xrandr with command xrandr --output LVDS1 --scale 1.4x1.4, this worked but again resulted to another problem, it does the scaling thing but the cursor is still blocked into the native screen resolution and I am not able to move it further, I found that the bug is already filed here. Also this command was only for Linux, I wanted to do this thing with both Linux and Windows (including Windows 8). I want a similar software that is bug free (at least not a major bug like this) and that supports Windows as well (or two separate software for Windows and Linux). Any help is appreciated and Thanks in advance.

• How to install custom c library?

  - by arijit

  I just wanted to add a c library to Ubuntu which was created by Harvard University for cs50 course. They provided instructions for how to install the library which is listed below. Debian, Ubuntu First become root, as with: sudo su - Then install the CS50 Library as follows: apt-get install gcc wget http://mirror.cs50.net/library/c/cs50-library-c-3.1.zip unzip cs50-library-c-3.1.zip rm -f cs50-library-c-3.1.zip cd cs50-library-c-3.1 gcc -c -ggdb -std=c99 cs50.c -o cs50.o ar rcs libcs50.a cs50.o chmod 0644 cs50.h libcs50.a mkdir -p /usr/local/include chmod 0755 /usr/local/include mv -f cs50.h /usr/local/include mkdir -p /usr/local/lib chmod 0755 /usr/local/lib mv -f libcs50.a /usr/local/lib cd .. rm -rf cs50-library-c-3.1 I did exactly as directed. But the compiler reported “Undefined reference to a function”--the function was Get String. So, I searched for a solution and found one. It said to use the -l switch. Now when I compile I use something like: gcc –o hello.c hello –lcs50 (I don’t remember the exact command.) However, I cannot use the make command, which is easier to use. I understand that there is some problem with linking the library. What is a good solution to this problem?

• Understanding and memorizing git rebase parameters

  - by Robert Dailey

  So far the most confusing portion of git is rebasing onto another branch. Specifically, it's the command line arguments that are confusing. Each time I want to rebase a small piece of one branch onto the tip of another, I have to review the git rebase documentation and it takes me about 5-10 minutes to understand what each of the 3 main arguments should be. git rebase <upstream> <branch> --onto <newbase> What is a good rule of thumb to help me memorize what each of these 3 parameters should be set to, given any kind of rebase onto another branch? Bear in mind I have gone over the git-rebase documentation again, and again, and again, and again (and again), but it's always difficult to understand (like a boring scientific white-paper or something). So at this point I feel I need to involve other people to help me grasp it. My goal is that I should never have to review the documentation for these basic parameters. I haven't been able to memorize them so far, and I've done a ton of rebases already. So it's a bit unusual that I've been able to memorize every other command and its parameters so far, but not rebase with --onto.

• startup Error for Zend Server CE

  - by Jamison

  Hello! I've got a strange startup error for Zend Server CE - it's probably easy to fix, but I don't have much experience with Zend Server! I'm running the latest OSX 10.6.6 and the latest Zend Server CE for Mac. When I run the "start" command from the command line, here is what I get: /usr/local/zend/bin/apachectl start [OK] spawn-fcgi: child spawned successfully: PID: 4206 /usr/local/zend/bin/shell_functions.rc: line 133: 4210 Bus error $WATCHDOG -i $BINARY 1>&3 2>&4 /usr/local/zend/bin/shell_functions.rc: line 133: 4211 Bus error $WATCHDOG -u $WD_UID -g $WD_GID -s $BINARY 1>&3 2>&4 Starting Zend Server GUI [Lighttpd] [FAILED] /usr/local/zend/bin/lighttpdctl.sh: line 46: 4212 Bus error $WATCHDOG -i $BINARY Starting MySQL SUCCESS! /usr/local/zend/bin/shell_functions.rc: line 133: 4304 Bus error $WATCHDOG -i $BINARY 1>&3 2>&4 /usr/local/zend/bin/shell_functions.rc: line 133: 4425 Bus error $WATCHDOG -u $WD_UID -g $WD_GID -s $BINARY 1>&3 2>&4 Starting Java bridge [FAILED] /usr/local/zend/bin/java_bridge.sh: line 39: 4426 Bus error $WATCHDOG -i $BINARY Zend Server started... The challenge is that ZEND SERVER wont open the GUI with this error, and seemingly I can click on Zend Server in the Applications folder and it opens for a second and immediately closes. I've made sure that Web Sharing is turned off to avoid conflicts, and I've run Disk Utility from my recovery disk to make sure there are no file system errors. Here is what the lines that are referenced in the errors have in terms of code: shell_functions.rc: (starting on line 132 - the error message says line 133...): launch() { if [ -z "$DEBUG" ]; then exec 3>/dev/null 4>&3 else exec 3>&1 4>&2 fi $WATCHDOG -i $BINARY 1>&3 2>&4 RET=$? if [ $RET -eq 0 ];then $ECHO_CMD "$BINARY watchdog is up and running.. ${OK_COLOR}[OK]${T_RESET}" return $RET else #$WATCHDOG -u $WD_UID -g $WD_GID -s $BINARY >> "$PREFIX/logs/watchdog_$BINARY.log" 2>&1 $WATCHDOG -u $WD_UID -g $WD_GID -s $BINARY 1>&3 2>&4 report $?
