Today is my last working day at SUSE. I spent wonderful five and a half years at this company. First starting as a package maintainer, learning more and more about the free software movement and its ecosystem. Later I moved to the newly created openSUSE Boosters Team, where I could apply everything I learned about FOSS communities in practice and help to create the best Linux distribution.

Recently I discovered my dormant passion for open hardware, be it analog or digital. I feel that’s where my heart is at the moment and that probably I could do a bigger change in this area.

The good thing is nothing changes from the community side of things. I’ll still be participating in openSUSE development and discussions on the mailinglists or IRC. So, please, put the champaigne back to the fridge, it’s not over yet. If you want to keep in touch and didn’t notice I started using prusnak@opensuse.org email address instead of the corporate ones some years ago, please change your address entries now.

I’m sure we’ll see each other very soon at some FOSS related event (most probably openSUSE Conference in which organisation I’m actively participating in). That’s why this blogpost is titled “See you soon!” rather than “Goodbye”. And of course, remember to have a lot of fun!

I was so psyched I created packages for all three of them. Simply add the openSUSE Games repository and install packages mari0, orthorobot or nottetris2 respectively to play. Dependency packages like love and lua will be installed automatically, of course.

Enjoy!

Update: I was just notified that Not Tetris 2 does not work with LÖVE 0.8.0. I might try to look at it soon.

I might implement other charts mentioned in the Stephen’s article in the future, but no promises.

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 create the level file in levels folder (for example 14.lvl) and select level 14 in the level chooser. For level definition see file format.txt in the same 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!

which produces this list:

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!
