• Swichable Graphics

  - by user67291

  Im having a bit of a problem with my 2 graphic card in my laptop. laptop: Acer Aspire 5553g Graphic Cards: Performance: ATI Mobility Radeon HD 5650 Power saving: ATI Radeon HD 4200. On this laptop i have used ubuntu 11.04, then upgraded to 11.11, and now upgraded to 12.04 the other day. The problem is that sins i upgraded to 12.04 im unable to switch to my performance graphic card using the Catalyst Control Center. Under 11.04 and 11.11 it was no problem. I open the Catalyst Control Center and select the performance option then apply, it tels me that it will be applied after reboot, I reboot and nothing has changed. Im able to "force" it by changing in BIOS, so i know there is nothing wrong with the card. Thanks /Daan

• Better Embedded 2012

  - by Valter Minute

  Il 24 e 25 Settembre 2012 a Firenze si svolgerà la conferenza “Better Embedded 2012”. Lo scopo della conferenza è quello di parlare di sistemi embedded a 360°, abbracciando sia lo sviluppo firmware, che i sistemi operativi e i toolkit dedicati alla realizzazione di sistemi dedicati. E’ un’ottima occasione per confrontarsi e, in soli due giorni, avere una panoramica ampia dall’hardware a Linux, da Android a Windows CE, dal .NET microframework a QT, senza troppi messaggi commerciali e con un’ottima apertura sia alle tecnologie commerciali che a quelle free e open source. Io parteciperò come speaker, parlando di Windows CE, ma anche come spettatore interessato a molte delle track di un programma che si va popolando e diventa mano a mano più interessante. Se volete cogliere l’occasione per visitare Firenze (che già sarebbe un motivo più che sufficiente!) e parlare di embedded, contattatemi perchè come speaker posso fornire un codice sconto che vi farà risparmiare un 20% sul prezzo della conferenza (che già è vantaggiosissimo, vista la quantità di contenuti dedicati all’embedded). Arrivederci a Firenze!

• Elegant ways to handle if(if else) else

  - by Benjol

  This is a minor niggle, but every time I have to code something like this, the repetition bothers me, but I'm not sure that any of the solutions aren't worse. if(FileExists(file)) { contents = OpenFile(file); // <-- prevents inclusion in if if(SomeTest(contents)) { DoSomething(contents); } else { DefaultAction(); } } else { DefaultAction(); } Is there a name for this kind of logic? Am I a tad too OCD? I'm open to evil code suggestions, if only for curiosity's sake...

• How does one handle sensitive data when using Github and Heroku?

  - by Jonas

  I am not yet accustomed with the way Git works (And wonder if someone besides Linus is ;)). If you use Heroku to host you application, you need to have your code checked in a Git repo. If you work on an open-source project, you are more likely going to share this repo on Github or other Git hosts. Some things should not be checked in the public repo; database passwords, API keys, certificates, etc... But these things still need to be part of the Git repo since you use it to push your code to Heroku. How to work with this use case? Note: I know that Heroku or PHPFog can use server variables to circumvent this problem. My question is more about how to "hide" parts of the code.

• Du nouveau sur Chrome OS : l'UI en partie dévoilée, le système d'exploitation de Google attendu fin

  Mise à jour du 14/05/10 Du nouveau sur Chrome OS : l'UI en partie dévoilée Le système d'exploitation de Google attendu fin juin pour les constructeurs Acer devrait présenter le mois prochain le premier portable à tourner sous Chrome OS. C'est en tout cas ce que croit savoir VentureBeat. Pourtant, les notes de développement du système d'exploitation de Google n'indiquent en rien que l'OS est finalisé, ni même qu'il soit sur le point de l'être. Ce qui ne signifie pas non plus que les choses n'avancent pas. Bien au contraire. La version actuelle de Chromium (le build open-source de Chrome OS) est la 0.7.41....

• How To Convert Virtual Machines Between VirtualBox and VMware

  - by Chris Hoffman

  Migrating to another virtual machine program can be intimidating. if you already have your virtual machines set up they way you like them, you don’t necessarily have to install them from scratch – you can migrate your existing virtual machines. VirtualBox and VMware use different virtual machine formats, but each supports the standard Open Virtualization Format. Convert your existing virtual machine to OVF or OVA and you’ll be able to import it into another virtual machine program. Unfortunately, this may not always work perfectly, as VirtualBox and VMware both seem to use slightly different OVA/OVF implementations that aren’t entirely compatible. If this doesn’t work, you may want to reinstall your virtual machine’s guest operating system from scratch. 8 Deadly Commands You Should Never Run on Linux 14 Special Google Searches That Show Instant Answers How To Create a Customized Windows 7 Installation Disc With Integrated Updates

• Samba network sharing NTFS drives and root permissions from local drives

  - by Bill

  I'm able to share my internal 2ndry NTFS drives (sdb1,2 and 3) on the network with Windows computers now but even though Samba read/write is enabled, Windows network computers can only open files "read-only" and can't save files to the samba shared drives/folders. I try to set permissions in Ubuntu via folder and/or file properties even logged in root via Nautilus but all the samba shared folders and files are set as owner = root, accessible and does not allow me to change them to read/write, it just resets to root, accessible, in other words, I can't change permissions. I'm running Ubuntu 11.04 Gnome on an old Dell Dimension 2400. Also, in order to for me to copy or move any files from the Ubuntu drive to the sdb1,2 or 3 drives, I have to gksu nautilus. This consequently prevents me from copying .ISO files to my "Multisys" thumb drive too.

• Point-in-time restore of database backup?

  - by TiborKaraszi

  SQL Server 2005 added the STOPAT option for the RESTORE DATABASE command. This sounds great - we can stop at some point in time during the database backup process was running! Or? No, we can't. Here follows some tech stuff why not, and then what the option is really meant for: A database backup includes all used extents and also all log records that were produced while the backup process was running (possibly older as well, to handle open transactions). When you restore such a backup, SQL Server...(read more)

• Edit 100MB+ file

  - by Majid Fouladpour

  I have captured some traffic with Wireshark and saved the result as a file. The file has 3 sections now: request headers response headers response body The response body is to become an flv file, but now everything is saved as a single file. So I need a way to delete the first two sections from the file, but the problem is that the file is very big (over a thousand mega bytes). I have tried to open it with gedit, but no matter how long I wait, gedit hangs and remains unresponsive until I kill it. What tool can I use to edit this big file easily?

• Why is the dash so unresponsive, and is there a way to fix this?

  - by Jon

  I just upgraded to 12.04. When I press the super key to open the dash, there's a lag of 1-3 seconds before it displays, with no other programs running. (This is similar, but not identical, to the issue described in Dash application search unresponsive at startup about 11.10.) At login time, this lag is up to 10 seconds, and sometimes the dash doesn't respond at all to the super key. In contrast, the launcher Kupfer immediately responds to its hotkey, in milliseconds, and responds to my typing an application name also in fractions of a second. Is there a way to load the dash in memory or a RAM disk of some sort to make it more responsive?

• Split screen and other issues on Ubuntu 11.10 with ATI graphics card

  - by garus

  Ever since updating my Ubuntu 11.04 to 11.10 I experience issues with graphics. The biggest is the "split screen" effect where my desktop is shifted to the right, resulting in having Unity bar in the middle of the screen. As shown here: http://i.imgur.com/I8nmZ.jpg This changes from boot to boot, sometimes it's on the left, sometimes in the middle. What I tried: Removing fglrx drivers completely Installing post-update version of them, but installation is broken ATM in the Ubuntu, so no go. No one is even trying to fix it (bug report https://bugs.launchpad.net/ubuntu/+source/nvidia-common/+bug/873058 and a couple of duplicates out there) Also using the open source "radeon" driver results in the same (I have a better successful boot ratio with this one, proprietary rarely lets me boot) Other artifacts are: serious screen tearing weird lines flickering in random places lagginess Did anyone experience that? My specs: Ubuntu 11.10 AMD Radeon HD 6950 1GB

• Windows 7 Virtual PC - &ldquo;RPC server unavailable&rdquo;

  - by Kelly Jones

  I use Windows 7 Virtual PC on my current project and I often bring home the files, so I can work some in the evenings.  Since my VHDs are large, I’ll only copy the undo disks, saved state, and virtual machine config files from my external drive.  I copy them to a small portable drive and once I get home, I’ll copy them to a large external drive. I’ve done this for over a year, but recently I started getting an error when I tried to start the VPC after the copying was finished.  It would open the initial window with the progress bar, but eventually the bar would stop, turn red, and then the error “RPC server unavailable” would appear.  When I first started seeing these, I’d try again, but no luck. After some testing, it turns out that my small portable drive is apparently going bad, so it was corrupting the files.  Lucky for me, that I never overwrote my good copies with corrupted copies, at least not at both the office and at home.

• What happens after `ubuntu-bug` has done it's thing?

  - by guntbert

  Until some time ago you ran apport-bug or ubuntu-bug to start reporting a bug. The system would then open launchpad with your account, upload the collected information and let you add more info to the bug report. Now when I run gksudo ubuntu-bug (for instance with a crash-file as argument) the common bug dialog appears and thats all. Where is the report being sent to? Definitely not to launchpad as a bug report (although in the concrete situation people have been able to file a report about that bug). So: where is this report sent to (and just maybe) how can I still file a bug report from my system (makes uploading of the pertaining files much easier) Could it be that "the system" decided that this would be a duplicate of an already existing bug?

• Screen dims on opening certain applications on Macbook

  - by yayu

  I have ubuntu 11.10 installed on an old 2008 macbook. There is an issue of screen dimming that I didnt find anywhere else on the forums. The issue is that the screen is dimmed when I open certain applications (Firefox, Software Center) and this cannot be readjusted by the physical brightness buttons on the keyboard. I tried a bunch of things on the barely barely visible screen, and had no choice but to restart. This has happened everytime. Does anyone know how to solve this?

• Mozilla reproche à Apple et Google de vouloir s'approprier le HTML5, tandis que Microsoft est félici

  Mozilla reproche à Apple et Google de vouloir s'approprier le HTML5, tandis que Microsoft est félicité pour son soutien de la technologie Christopher Blizzard, évangéliste Open Source chez Mozilla, tire à boulets rouges sur Apple et Google.

• Cinnamon Settings blank after update

  - by Seth Balmore

  Using Ubuntu 12.04 with the cinnamon desktop, I installed the most recent updates and now when I open "System Settings" the entire window appears as a blank white screen. The headers for APPEARANCE, PREFERENCES, and HARDWARE are present, but the usual icons for *Background, *Hot Corners, *Printers, etc. are no longer visible. Some of these settings can still be altered via the terminal: cinnamon-settings backgrounds cinnamon-settings applets cinnamon-settings mouse and touchpad But other commands, such as cinnamon-settings hot corners are met with an error. This is obviously a problem with cinnamon, so I just want to bring it to attention and find out when they plan on fixing the bug. A workaround can be found on the web, but it seems way to risky to rely on.

• Can I hook my xbox up to my Ubuntu PC

  - by Anonymous John

  My old xbox 360 won't eject disks, it makes a sound,but won't open. I want to play games, so I think I could hook it up to my PC running Ubuntu 13.10 64-bit and maybe I could use my PC's DVD drive. Can this work at all, or am I just crazy? There is an HDMI port on the back of my graphics card. If I can't do that, is there any software for Ubuntu that can rip the game off of a CD and put it on a flash drive? I have heard xbmcbuntu works great for gaming, but it doesn't work with my PC.

• The /usr/bin/x11 folder

  - by WrecklessT

  Why does the /usr/bin/x11 folder hold another x11 folder and when you open that === x11 you get another x11 and then another and another??? I did it about 6 times and got frustrated so I have no idea how deep this goes but What is the purpose (or is it a glich?)? Is this eating disk space more than it should? (I was going to delete one or more but thought I better ask first before I end up !fucked ) and finally Is it just me and I am going crazy maybe the pills are wearing off or maybe they are kicking in.. I am not sure but an answer would help. I can see no reason why this should be happening at all.
