One of the ideas how to help with Open Build Service adoption was to create some kind of download widget that would be possible to embed into upstream projects’ download pages. After a few days of work I ended up with the page that is now available from this URL:

http://software.opensuse.org/download?project=PROJECT&package=PACKAGE

It contains instructions for all distributions (like adding repo and installing the package), provides direct link to packages (which I recommend using only as a last resort solution), and for SUSE/openSUSE there are One-Click-Install buttons. The page also automatically preselects your distribution (if it’s possible to guess from user agent).

Go to http://software.opensuse.org/download?project=openSUSE:Tools&package=osc to see the page in action. You can also embed the page using slightly modified URL into your download page:

<iframe src="http://software.opensuse.org/download/iframe?project=openSUSE:Tools&package=osc"></iframe>

If you want to modify the default color theme just use the following GET attributes (acolor – link color, bcolor – background color, fcolor – foreground color, hcolor – headers color). They accept standard HTML color values like 123 or 112233 (without the #).

PS: Some projects (like for example Geogebra) are already using this, although it was not yet properly announced. Feel free to join them if you think it’s a good idea!

The theme selected for this year’s edition was Ouroboros.

At first I created one concept, but later I realized it’s just a toy and it would be very hard to turn it into a playable game, so I decided to scratch it. Then I got the idea to create a puzzle game played on similar board like Hexxagon, but instead of individual stones you have 2-6 snakes and your objective is to move and/or rotate them in order to create one big cycle consisting of all of them.

This is how the game looked immediately after the contest (clicking on the image will launch the YouTube video).

I was very surprised that I won the second place with this game in the local competition, because all entries were great and to be honest I did not expect it. Thanks for your support!

If you want to try the game for yourself you can either checkout the source code or download a ZIP or TAR archives. After that make sure you have the latest LÖVE engine installed and run start.bat (Windows) or start.sh (Linux/MacOSX).

If you want to help me with the levels, just edit the file levels/level.lvl and restart the game. For level definition see file format.txt in the levels folder. Thank you!

#!/bin/bash
tmpfile=$(mktemp)
for i in $(seq 2 254); do
    ssh-keyscan -t rsa,dsa,ecdsa 192.168.1.$i >> $tmpfile
done
ssh-keygen -l -f $tmpfile
rm -f $tmpfile

First, we retrieve the keys using ssh-keyscan, store them into temporary file and compute fingerprints afterwards using ssh-keygen. Or is there a less complex and more elegant solution?

PS: Thanks David for kicking in the right direction.

I’m pretty excited when I look closer at the just published Conference Timetable. What I really like about the openSUSE Conference is that it has also sessions that are not directly related to SUSE or Linux in general. You can “geek out” about topics like Digital processing of early color photography, Open Street Map, 8-bit Music, Wooden kayaks or Open Hardware and Hackerspaces. The last one will be held by me and I’ll try to bring a functional Rep Rap 3d printer from our Prague hackerspace brmlab so you can see it in action and print your own 3d models. All in the spirit of our motto: Have a lot of fun!

Together with Henne and Tom we’ll hold a workshop about our social networking platform called Connect and we hope we’ll get more contributors to it.

Among the talks I mentioned I also plan to visit sessions about GNOME 3, tmux, 5Ws of Contributions, Static Code Checking and Lightning Talks. And of course don’t miss the keynotes and social event The Geek in Wild West theme!

See you all there!

Come on, join our IRC channels and have a lot of fun!

Nifty, right? The idea is simple. I use the sort_by function which pre-computes the values that are later compared. I replace some special values like “_Factory” or “_SP”, because I want “Factory” to be the newest (100 is higher than any other openSUSE version) and “11_SP1″ to behave exactly like “11.1″. Then I split the key using the “_” delimiter and turn any string in form “digit” or “digit.digit” to float number. I change the sign, because I want versions to be sorted in the reverse direction. Good thing is that Ruby operator <=> works on arrays also, so I’m done with key modifications and the sort does the rest …

PS: I used |key,val| in sort_by block because I want to use this function also to sort hashes by their key. This way it works both for arrays and hashes with any further modifications.

I’ve set a git repo on Gitorious and also built the package in my home:prusnak project. If there will be interest from our GNOME Team, I will create a submit request to some GNOME devel project and Factory as well.

If you don’t know this yet, you have to install the gnome-shell-extension-yast-status-menu and then either logout and login or press Alt+F2 and type “r” (which will restart gnome-shell).

Enjoy!

Take a look at the following picture to see how it works:

or check the video on youtube.

The number between user@host and the current working directory is the exit status of the most recently executed command (or pipeline). This is great because you don’t have to type echo $? everytime you want to find it out. The __git_ps1 magic will print git branch name if you are inside of the git repository. Furthermore it will add special characters indicating the state of the repo: % – untracked files present, + – new files added, * – some tracked files changed, $ – there is something in the stash (see git stash --help). Pretty cool, right?

Later I had some time to practice my 1337 GIMP skillz and created a motivational poster for your viewing pleasure. After Geeko Bus and Geeko Tram I give you without further ado the “openSUSE Spacebus!”:

Please go to GNOME-Shell Extension: YaST (item in) Status Menu.

I read a blogpost from Nelson Marques about adding YaST modules icon to GNOME Shell. I kind of liked the idea of YaST integration into GNOME Shell, but I had to share Julian Aloofi’s worries in comments. He came up with a simple idea to just add the YaST menuitem to status menu in the top-right corner. This was very easy to implement because most of the GNOME Shell features are written in Javascript. I created the following simple hack and ended up with this:

If you want to add the YaST menuitem as well, just follow these simple steps (as root):

cd /
wget https://gist.github.com/raw/8d0d7d756e18b8a1da21/131a6caae2556edaa045f9cc3f13c573e12f2d31/gnome3-statusmenu-yast.patch
patch -p1 < gnome3-statusmenu-yast.patch
rm gnome3-statusmenu-yast.patch

Now you have to restart GNOME Shell (press Alt+F2 and enter “r” command) and you can enjoy the new menu item. Remember, the changes will be lost next time you reinstall the gnome-shell package.

I already contacted Frederic and Vincent about the patch and they are still looking for the best way how to integrate YaST with the rest of the system, so stay tuned.

PS: Andy found an interesting bug. For him, the item was added but clicking on it did nothing. Solution was found by Frederic – just install the missing gnome-menus-branding-openSUSE package.
