World of Warcraft in Linux using Wine

Many manuals of installing and using World of Warcraft (or simply WoW) in Linux using Wine (Windows emulation) are outdated and provide lots of complex instructions for old Wine version. The truth is very simple:

  1. Take a recent Wine version. Any version from this year (2007) will do. Debian and Ubuntu users can either use the wine from the latest releases of the distros or use the repositories.

  2. Install WoW via the usual installer

  3. Edit $WOW/WTF/ and add following lines:

    SET gxApi "OpenGL"
    SET SoundOutputSystem "1"
    SET SoundBufferSize "100"

  4. Run 'wine regedit' and set HKEY_CURRENT_USER->Software->Wine->OpenGL->DisabledExtensions to "GL_ARB_vertex_buffer_object" (you will need to create this string value)

SBackup new beta - test and translate please!

With great help from Ouattara Oumar Aziz an new version of SBackup is shaping up in the svn repo and a day ago I created a public beta version - 0.10.4~beta10 which can be downloaded here.
Please report any bugs or regressions to Sourceforge bug tracker. Also an update for translations and new translations can be added. You can either translate in Launchpad or download the template file from the SVN. But beware that there are more translations in Launchpad then in the SVN at the moment, so check there first.
If no blocker bugs are found, we could see a new stable release of SBackup in a weeks time. I am sure that a lot of people will be happy to hear that :).

Home folder organisation

After last post about a FHS amendment to address the structure of user's home folders, I received a lot of comments and there is one very significant thing that can be changed in the proposal - instead of having $HOME/{.data|.cache|.config}/appname structure, to change that to a mandatory $HOME/.library/appname/{cache|config|...} . This version still has all the benefits of the first solution (configuration for an application can be easily identified and erase, and all cache can easily be excluded from backups using "$HOME/.library/*/cache" regexp) and also has additional benefits, main of which is the ability to later introduce the concept of user installed packages. The idea is that it would be possible to support having /bin, /lib and /share subdirectories in these application directories thus making an ability for the whole application to e packed in a single directory and allowing the application to be installed simply by unpacking this directory. I admit that much of this is glanced over from MacOS X world, but I do not think that it diminishes the idea itself.
Some problems appear there - support of these distributed bin folders, support of separate lib folders, handling of application plugins, handling of dependencies, handling of the application menu, upgrading notifications for the user software vs. system software. But nothing there that can not be solved. I feel that this can bring together FHS and LSB by providing something of an API for software being installed by users. Having no registry of the software in this solution allows for some interesting things, for example having multiple versions of one program just by renaming the application folder.
A lot of specification work is required here, therefore I proposed a workshop on this topic in Debconf7. I hope to have something that everyone can agree on and maybe even some code by then, so that after Debconf7 there can be a formal policy amendment proposal.

FHS extension for user home folders


Currently there is a huge mess of files and folders that start with a "." in any users home folder. There is no structure or policy on how applications should choose file and folder names for data that needs to be stored in users home directory. Additionally there is no established consistency between Gnome, KDE and most other applications. Gnome application have part of their configuration information in gconf folder and other part in a gnome subfolder. KDE applications have a complex structure under .kde/. And most other applications either have one file directly in users home folder or have their own dot-folder there.

Another type of bounty

It would be very good to have a bounty that would pay 100$ to anyone who would find and implement a way to reduce memory use of a fully running Debian Linux + Gnome system (optionally, with all Gnome apps loaded) by one megabyte (as indicated by RAM used in a swapless system - (cache+buffers)) in a way that does not reduce functionality or heavily compromise runtime speed and would be accepted into upstream Gnome.

Wrong partition ordering

If you have a hard drive with two or more logical partitions in one extended partition and then proceed to erase the first of those logical partitions (in GParted), then you will soon discover that the number of the second logical partition changed (from sda6 to sda5 in my case). If you then try to create a partition in the free space and launch cfdisk, you will notice that there is no free space where it should have been. If you then manage to get to GParted and create a partition there, then do not relax, as your perils are not yet over. Upon reboot you will find that the logical partition that is in the beginning of the logical partition got a new number (sda7 in my case) and the your valuable second logical partition is still numbered wrongly (it was sda5 instead of expected sda6). Even more so, if you try to fix it with cfdisk, it bails out with a fatal error of overlapping extended partitions.

Die C

I am not a good coder. In my mind a coder is determined by how much he loves C (or, in clinical cases, assembler). I hate C and avoid it whenever I can, because I am always off-by-one, and often even in more then one place, which make debugging even more .. fun. :(

SBackup 0.10 is out!

Get it while it's hot! It has been uploaded to Debian and will get to the mirrors in a day or two, but if you really want it now, then grab 0.10 release from Sourceforge.

SBackup 0.10 delayed to tomorrow


* more testing for the new restore backend and of the purge function are needed to ensure that they work as expected in all expected situations;

* I need more time to review a last minute patch to add autotools support to SBackup and decide if I want that or not;

* My primary notebook is coming back from Dell Service tomorrow and I need it to test the upgrading of the package in Debian (and not just Ubuntu that I have on my old/secondary notebook).


My plea has been answered by a DVFS project specification. For some strange reason, my edits do not show up in the wiki page and the blog of its creator is not reachable, so I post it here.
