  I installed XBMC and it's working beautifully. I have my own skin I'd like to use and all I should have to do is copy and past my skin.folder into the addons folder and I'm down.

• How do I fix these compiler errors in Apple Crunch?

  - by BluFire

  I've been looking around and I finally got the full source code for a game called Apple-Crunch from Google Code. But when I put it into my project, the source code included so many errors in the class files such as: cannot be resolved into a type the constructor is undefined the method method() is undefined for the type Sprite class.java I downloaded the source directly from the command-line and noticed errors popping up on my project. Since I couldn't figure out how to import the actual folder into my workspace (it wouldn't show up on existing projects) I decided to copy and overwrite the folders into the project. The errors were still there so I looked at the class files and noticed that the classes with errors extended from RokonActivity. I then proceeded to add to the libs folder the Rokon library in hopes to fix the errors. Sadly it didn't work and now I don't what to do to fix the errors. How do I fix the errors without having to manually change the code? The source code should be fully functional so why are there errors?

• audio controls in xfce 4.8

  - by Peter

  I am seeing several questions similar to mine, but none of the answers are sufficient. I am pretty green with Ubuntu, so here goes: I was just automatically upgraded to xfce 4.8 for Ubuntu studio. The volume control no longer works in my panel. When I launch 'mixer' I don't see any settings, either. When I try to run "linux audio configuration" I get an error: JACK can only be configured with a loaded and stopped studio. Please create a new studio or load and stop an existing one. I understand that I can change the volume using command line, but I can't understand why I got upgraded to something that fails on basic features. I much less likely to recommend ubuntu to others as a result. thanks!

• apt-get install does not work. Gives the same error every time E: Unable to locate package

  - by SAMEER

  There is an issue, for every package that I try to install. I am using VMWare Player 3.16 & I have installed Ubuntu 12.04. The error is: E:Unable to locate package (PACKAGE NAME) Also, another problem is that there are some configuration errors. So I have to use the CLI rather than the GUI. Now if this is a network error, I'm not sure as to how to open the setting from the command prompt. Even if I get to the GUI, it might not work, as the shortcuts are not available.

• Why does sound stop working after a while?

  - by badp

  I don't know how to reproduce this problem, because I don't regularly play music or sound. All I know is that, sometimes, I'll load a video (from youtube or from a local file) and there will be no sound. Everything looks fine software wise: Rebooting always fixes. aplay, paplay and pals give no error message I'm not in the audio group, as advised The device exists and appears in use: $ lsof /dev/snd/by-path/pci-0000\:00\:1b.0 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME pulseaudi 17313 badp 23u CHR 116,10 0t0 7628 /dev/snd/by-path/../controlC0 pulseaudi 17313 badp 30u CHR 116,10 0t0 7628 /dev/snd/by-path/../controlC0 Restarting pulseaudio or alsa seems to do no good. What is wrong here?

• My ubuntuone is broken, what is the problem?

  - by user6962

  I am on 10.10 and u1sdtool seems to be completely broken. I reinstalled it, no change. I can add my PC to the account, but it is added twice(!) every time I tried. So I have my netbook and two times my PC in the account. The netbook with 10.04 has no problems. Below is the error msg I get when attempting to startup Ubuntu One on the command line. desktop:~$ u1sdtool --status Oops, an error ocurred: Traceback (most recent call last): Failure: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. desktop:~$ Starting it from the Me Menu has the same effect, the HDD will get really busy for a minute and then nothing happens, the client will not start. Nothing in the syslog or anywhere.

• Getting Windows Azure SDK 1.1 To Talk To A Local DB

  - by Richard Jones

  Just found this, if you’re using Azure 1.1,  which you probably will be if yo'u’ve moved to Visual Studio 2010. To change the default database to something other than sqlexpress for Development Storage do this - Look at this - http://msdn.microsoft.com/en-us/library/dd203058.aspx At the bottom it states -   Using Development Storage with SQL Server Express 2008 By default the local Windows Group BUILTIN\Administrator is not included in the SQL Server sysadmin server role on new SQL Server Express 2008 installations.  Add yourself to the sysadmin role in order to use the Development Storage Services on SQL Server Express 2008.  See SQL Server 2008 Security Changes for more information. Changing the SQL Server instance used by Development Storage By default, the Development Storage will use the SQL Express instance.  This can be changed by calling “DSInit.exe /sqlinstance:<SQL Server instance>” from the Windows Azure SDK command prompt.

• git in non-distributed, independent, lone programming ...best practice(s) ?

  - by explorest

  I am currently studying the git documentation to get a hang of distributed version control workflow and use of git command line. I want to first start using git with small, personal, pet projects so to gain experience before doing it on large scale (i.e., bigger projects, team dev). What areas of the git system should I, as a lone player, devote most of my study time to... what parts should I leave for the larger scale work later on. In other words what features of the git system will fully be grasped in team work only, and therefore should not be too involved with at an individual level?

Regular Expression HTML and CSS HTTP Web programming language (PHP, Ruby, etc.) SQL (command based, not GUI, since most server environment uses terminal only) Javascript and library (jQuery) Versioning (SVN, Git) Unit and functional test Tools Build tools (Ant, NAnt, Maven) Debugging tools (Firebug, Fiddler) Mastering the above makes you a good web developer. Any comments?

• Grab sound of a SDL game with ffmpeg/avconv

  - by Peregring-lk

  I'm trying to make a screencast of a SDL game which I developed some years ago, with the following command: sleep 5 && avconv -f x11grab -s 1366x768 -r 25 -i :0.0 -same_quant screen_cast.mkv (in this 5 seconds of sleep, I open the game). But the generated video (screen_cast.mkv) doesn't capture audio. I use for my game the SDL_Mixer library, with default configuration (22050 for frequency, AUDIO_S16SYS for format, and 2 channels). What's the problem? (with options -f alsa -i pulse it doesn't work either).

• How to make xlock use the first key I hit as a part of my password

  - by alesplin

  I just switched from Arch Linux to Ubuntu 10.10. I'm running the Fluxbox window manager, and I use xlockmore to lock my screen with the following key shortcut: 192 :Exec xlock-mode marquee +usefirst -icongeometry 240x240 -message "back in a minute..." The problem I'm having is that xlock is definitely not using my first key as part of my password. Instead, it uses some randomized fade pattern to fade to the password screen. I find this highly annoying, as when I get back to my desk and start entering my password it doesn't register password characters until the fade pattern is complete. I've also tried the following modifications with no difference: 192 :Exec xlock -mode marquee -usefirst -icongeometry 240x240 -message "back in a minute..." 192 :Exec xlock -mode marquee -icongeometry 240x240 -message "back in a minute..." The first example worked flawlessly on Arch. Does Ubuntu have some sort of system default that you can't override on the command-line?

• 2D basic map system

  - by Cyril

  i'm currently coding a 2D game in Java, and I would like to have some clues on how-to build this system : the screen is moving on a grander map, for instance, the screen represent 800*600 units on a 100K*100K map. When you command your unit to go to another position, the screen move on this map AND when you move your mouse on a side or another of the screen, you move the screen on the map. Not sure that i'm clear, but we can retrieve this system in most RTS games (warcraft/starcraft for example). I'm currently using Slick 2D. Any idea ? Thanks.

• Computer logout after closing the lid

  - by ejp1087

  I would like my computer to logout every time I close the lid. And by that I mean log out completely. Basically I want the startup applications to run every time I open the lid to my computer. Right now, it just locks the screen and comes right back when I type in my password. It would be really great if I can have it such that the startup applications run every time I open the lid. However, would logging out lose any unsaved files? Alternatively, do you know if there is a way to run a command every time I open the lid? Thanks!

• How to install Visual Studio 2010 Search References and Pro Power Tools side by side

  - by Daniel Cazzulino

  The new Visual Studio 2010 Pro Power Tools bring a new Add Reference dialog that completely replaces the classic one when you click the familiar Add Reference command: It seems like a nice dialog that is more aligned with the new Add New dialog and the Extension Manager one. But for this particular case, I believe it's awfully overkill (what's the use of that right sidebar? what's the use for the categories of assemblies split between Framework and Extensions?). The (also new) Search References extension which I blogged about earlier, gives you the familiar classic dialog enhanced with the must-have Search capability:...Read full article

• How to reboot into Windows from Ubuntu?

  - by andrewsomething

  I'm looking for a way to reboot into Windows from Ubuntu on a 10.10/Vista dual boot system. The specific use case is that I would like to be able to ssh into my running Ubuntu instance and issue a command that will initiate a reboot directly into Windows. I found a promising blog post, but the script that it suggests isn't working: #!/bin/bash WINDOWS_ENTRY=`grep menuentry /boot/grub/grub.cfg | grep --line-number Windows` MENU_NUMBER=$(( `echo $WINDOWS_ENTRY | sed -e "s/:.*//"` - 1 )) sudo grub-reboot $MENU_NUMBER sudo reboot man grub-reboot isn't much help, but it seems to be leading me in the right direction: set the default boot entry for GRUB, for the next boot only WINDOWS_ENTRY=`grep menuentry /boot/grub/grub.cfg | grep --line-number Windows` MENU_NUMBER=$(( `echo $WINDOWS_ENTRY | sed -e "s/:.*//"` - 1 )) echo $MENU_NUMBER This returns the expected value, but on reboot the first menu entry is still highlighted. Any ideas why this isn't working or suggestions for other solutions?
