I have been learning a bit of Mono over the last couple of months and yesterday I decided that I wanted my code in a verison control system. The choice fell on Bazaar for various reasons which is unimportant and uninteresting at this point. Right now I just wanna write down how I did 
First off you tell Bazaar who you are with:
bzr whoami "Jacob Emcken "
To test it is set correct just type:
bzr whoami
Jacob Emcken
For the sake of it, lets imagine my project I want to version control is called Starfire.
Go to the directory with the project and initialze the directory as a Bazaar branch:
cd Projects/Starfire
bzr init
Within that directory a new directory called .bzr will be created:
ls -la
drwxr-xr-x 5 je je 4096 2007-09-01 23:56 .
drwxr-xr-x 3 je je 4096 2007-09-01 23:37 ..
drwxr-xr-x 6 je je 4096 2007-09-01 23:37 .bzr
drwxr-xr-x 2 je je 4096 2007-09-01 23:37 Glade
-rw-r--r-- 1 je je 5342 2007-09-01 23:37 Starfire.cs
-rw-r-xr-x 1 je je 5342 2007-09-01 23:40 Starfire.exe
Now tell Bazaar which files your branch consist of. In the following example we’ll tell Bazaar to ignore Starfire.exe because we dont need the compiled file within our version control:
bzr ignore Starfire.exe
bzr add .
added Glade
added Starfire.cs
added Glade/gui.glade
ignored 1 file(s).
If you wish to add some of these files, please add them by name.
Ignored files is found in the file .bzrignore, just try run ls -la if you wont take my word for it 
And finally to actual save the code in the branch repository commit your files:
bzr commit -m "Initial revision"
added .bzrignore
added Glade
added Starfire.cs
added Glade/gui.glade
Committed revision 1.
By supplying commit with the parameter -m you avoid a text editor popping up asking you for a commit message.
Now you can just hack away and you can check changes with:
bzr diff
Whenever you want to save you changes to the branch, just do a commit again. In the following example I change a line in Starfire.cs:
bzr commit -m "Fixed small typo"
modified Starfire.cs
Committed revision 2.
Now if you want to make your code available on the another machine ie. a server on the internet you can push you code out there through ssh (and ftp). Place yourself in the root directory of your project. The following example will push the branch out to my server (emcken.dk) where I have a ssh key so I dont need to write a password when logging in:
bzr push sftp://emcken.dk/~/development/Starfire
Now a copy of my branch is available in my home directory on my server (/home/je/development/Starfire).
As a last thing I would like my server to be central for my development. From the root directory of my project I tell Bazaar that my current branch is a checkout of the branch on my server:
bzr bind sftp://emcken.dk/~/development/Starfire
Now whenever I commit changes they will be committed to the server as well so I don’t need to push the copy of the branch out there every time. You can test the settings with:
bzr info
My experience with version control systems are very limited to say the least which was why some of the above wasn’t obvious to me before I made a few tests and read the man pages. But the above was what I needed to get started and I hope that this might help someone else. You can find more inspiration here and here.
I was cleaning my (computer) desktop and found this video about a helpdesk from medieval times ( sadly it is in Norwegian 
).
I had saved it on purpose because I though it was so funny. Now I found it on YouTube… deleted
Today I got dual screen in Ubuntu working… I have been fiddling around with it a few times before but nothing seriously. Never got it working the way I wanted. Earlier I edited the xorg.conf by hand while following guides from the internet and yesterday I stumbled upon a graphical Nvidia X configuration tool by accident… the solution was a bit of both.
The tool is called nvidia-settings and looks something like the image below.
As far as I know there are 2 ways of doing dual screen in Linux. Either you can use Xinerama or the Nvidia built-in feature called TwinView (I might be wrong here ). Anyways I chose TviewView because that was the default in the Nvidia config tool. After making X aware of my second monitor with the Nvidia tool I saved the X configuration and restarted the X server with the new (Nvidia generated) configuration. The Nvidia generated configuration had 2 problems:
- It removed my danish keyboard
- It made my old monitor and the VGA outled the default monitor.
I want my new monitor on the DVI outled to be the default.
By hand I added the danish keyboard configuration which I copy-pasted from the old xorg.conf:
Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "CoreKeyboard"
Option "XkbRules" "xorg"
Option "XkbModel" "pc104"
Option "XkbLayout" "dk"
EndSection
To force the DVI to be the primary monitor I used the following:
Section "Device"
Identifier "NVIDIA Corporation NV43 [GeForce 6600]"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce 6600"
BusID "PCI:1:0:0"
Option "NoLogo" "1"
Option "TwinView" "1"
Option "TwinViewXineramaInfoOrder" "DFP, CRT"
Option "TwinViewOrientation" "LeftOf"
Option "MetaModes" "DFP: 1600x1200, CRT: 1280x1024"
EndSection
Section "Screen"
Identifier "Screen0"
Device "NVIDIA Corporation NV43 [GeForce 6600]"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
First I don’t want to see the Nvidia Logo when X is started… it is a nice logo though 
TwinViewXineramaInfoOrder is the important part because this makes sure that the DVI is the default monitor. You can read more about all the possible options for the Nvidia driver on Nvidias homepage.
My only “problem” is that the background image is streched out on both monitors, but I guess I have to make a custom background image for my dual screen setup. Now I can play World of Warcraft in a dual screen setup in Linux as well which was one of the only things that kept me booting into Windows. To bad performance drops a bit in Linux But I have a strong feeling that we are to blame Nvidia for that rather than Wine… but its just a gut feeling.
Last week I attended a Xen course on SLES10 (SP1 RC5). We used virt-manager.
I looked for it in Ubuntu but wasn’t able to find it. Instead I found this request for packaging virt-manager for Ubuntu.
I have been trying to do it myself but it isn’t as easy as I thought… I have never really tried packaging anything before (apart from my wallpapers which doesn’t really have any dependencies or make files).
Virtual Machine Manager has the following dependancies (taken from virt-manager homepage):
python >= 2.4
pygtk2 >= 1.99.12-6
gnome-python2-gconf >= 1.99.11-7
libvirt-python >= 0.2.1
dbus-python >= 0.61
gnome-python-desktop >= 2.15.4
libxml2-python >= 2.6.23
vte >= 0.12.2
virtinst >= 0.103.0
Identified corespondent packages in Ubuntu:
python Version: 2.5.1-0ubuntu3
python-gtk2 Version: 2.10.4-0ubuntu3
python-gconf Version: 2.18.0-0ubuntu1
python-libvirt Version: 0.1.8-0ubuntu2
python-dbus Version: 0.80.2-1ubuntu2
python-gnome2-desktop Version: 2.18.0-0ubuntu3
python-libxml2 Version: 2.6.27.dfsg-1ubuntu3
libvte9 Version: 1:0.16.1-0ubuntu1
virtinst (downloadable from `virt-manager`'s homepage)
I guess virtinst would need packaging as well… download virtinst.
The version of phyton-libvirt isn’t new enough either.
I have been looking at a Ubuntu packaging guide but have already run into trouble (even before getting to phyton-libvirt):
...
checking for PYGTK2... configure: error: Package requirements (pygtk-2.0 >= 1.99.11) were not met:
No package 'pygtk-2.0' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables PYGTK2_CFLAGS
and PYGTK2_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
make: *** [config.status] Error 1
At work today I found an old SCO evaluation CD. A paragraph at the back of the CD cover made me laugh:
> SCO – a tightly integrated set of products which give you the best of both worlds – the power and reliability of UNIX and the freedom of Windows.
The “freedom” of Windows… what is that? :-O Click on the link below for full image.
This week I’ve been on a course to prepare for the Novell Certified Linux Engineer (CLE) which is required (and payed) by my employer.
But to take the CLE certification test you need to be CLP certified first, so today I took the CLP certification.
Now I’m ready to do the CLE tomorrow.
I’ve been working with Linux for some years now so the test wasn’t really that hard. Actually I was disappointed that I only got 718 points, I would have expected more. Anyways it is passed so who cares Don’t know what to expect from tomorrows test, I hope it is as easy as this one.
(Ubuntu is still my preferred Linux distro… but don’t tell Novell sssshhh)
Open Source ftw (sorry I’m mentally damaged from playing World of Warcraft, so I tend to use a lot of acronyms).
Just switched the emotion icons in my Serendipity installation with Tango ones. Here is how they look:
:’( 
:-D 
Sadly Serendipity doesn’t support more… I guess I would easily be able to add more by altering the code. It is PHP code after all, but I’m not bothered to do the change with every update of Serendipity. Anyway I got inspired by reading about Tango Smilies in WordPress by Jeff Waugh.
I knew the icons existed in the instant messenger Pidgin after reading a blog post from the icon author. I have installed Pidgin on my Ubuntu machines and found the icons in:
/usr/local/share/pixmaps/pidgin/emotes/default
I think its kinda hidden. You might have wondered why vmware-server kernel modules was available from the repositories but no vmware-server? The answer is: It is available!
Just like Real Player, Opera and other commercial software you can install VMware-server from the following repository, which you add to System -> Administration -> Software Sources and Third-Party Software:
deb http://archive.canonical.com/ubuntu feisty-commercial main
After that you run:
sudo apt-get update
sudo apt-get install vmware-server
A colleague pointed me a page about adding Adding Canonical Commercial Repositories in Ubuntu, which is actually referenced from the page about Installtion VMware Server in Ubuntu
For those who doesn’t know… a few years back I made the site www.debianart.dk which was supposed to be the center of graphics for Debian. It never took off, mostly because I didn’t really have the time and it didn’t help that I started using Ubuntu instead. I was running Debian unstable at the time because I wanted the latest and greatest (Gnome among other things) so the jump to Ubuntu wasn’t really that big.
Now I use the debianart.dk to host my own Debian wallpapers which I’m actually quite proud of
Even though I use Ubuntu now for my laptop and workstation, I still use my own wallpapers (mostly “apt-get install”).
Right before my interest died for debianart.dk I made a Debian package with all the four wallpapers I have made public. Once installed they would automatically be available when changing background in Gnome. A later version of Gnome changed the location of where you should register background images, and I never got it updated… until now. I got an email from a guy asking how the Debian package worked, which made me pull my head of of my ass and get the update done

In the lastest version of Ubuntu (version 7.04 – Feisty Fawn) kernel modules for VMware Server is available in the package vmware-server-kernel-modules from Ubuntus package repository.
The VMware Server itself is at the moment not. You still need to install VMware Server from the tar.gz download from www.vmware.com.
I found documentation on how to make the VMware server kernel modules package work together with the VMware Server installed from tar.gz in the Ubuntu Documentation. I also found the reference to this documentation on the Ubuntu Forums.
The cool thing about this is that you don’t need to run vmware-config.pl every time you update your kernel.
If you upgraded to 7.04 from a previous version of Ubuntu you might run into a problem where you can’t get the vmware console to start. The output on the console will look something like this:
/usr/lib/vmware/bin/vmware: /usr/lib/vmware/lib/libpng12.so.0/libpng12.so.0: no version information available (required by /usr/lib/libcairo.so.2)
I solved it by removing the following packages:
sudo apt-get --purge remove libdbus-1-2 libnautilus-burn3
Don’t worry new packages have taken their spots as far as I know:
libdbus-1-3
libnautilus-burn4
I found a thread on the VMware forums but my solution seemed easier
