One hundredth article anniversary

We, the authors of MyGNU.de are proud to celebrate an anniversary today. This is the one hundredth article published on this blog. But how does one celebrate such an anniversary? For sure, the best way is to write another article. Well, and perhaps drinking a beer or two.

Lets summarize some history. This blog, MyGNU.de started on November 29th 2008 – roughly three years ago. During these years Thorsten and I had the opportunity to provide useful information, helpful scripts and programs to you, our readers. – At least we hope so. This way we have been able to give something back to the open source community that has supported us in so many ways. We have written about solutions to many problems, regarding the Linux operating system, we encountered. It would be to much to write if I tried to mention every single article now, but some have to be mentioned.  For sure the highlights, that can be found on this website are SIV, the stereoscopic image viewer and vrtrack the headtracking driver for the Vuzix VR920 head mounted display.  The most popular download until now has been the Iptables Mirror target, which I ported to 2.6 and 3.x Linux kernels. The kernel module enables one to create a more active Iptables firewall by returning the attack to the attacker. In total it got 5897 hits until today. In the beginning some of the articles were shorter than the more recent ones, but with time our knowledge and writing skills evolved and some recent articles are of quite high quality. We hope you have enjoyed reading the articles and got some useful insights and information.

For the future we hope to keep on this way and improve our skills, to write better and more useful articles and software and publish these on MyGNU.de.

“So say we all.”

Well, now there is only one last thing to to do. To say thank you! We have to say thanks to you for reading, and we have to say thank you to our company the main-host.de GmbH for providing the webspace for this blog.

Happy anniversary MyGNU.de!

best regards and keep on reading

Jürgen

Vultures-2.2.100 ebuild for gentoo

Some years ago I played nethack on my old PC. Nethack is a Diablo like RPG that was originally released in 1987. Before playing a game, you have to create a character. You can choose between different character classes: Archeologist, Barbarian, Caveman, Healer, Knight, Monk, Priest, Ranger, Rogue, Samurai, Tourist Valkyrie and Wizard. These classes have different abilities in fighting and using magic. Afterwards you can descent to the dungeon where you have to retrieve the Amulet of Yendor and defeat the bad Moloch. For some more information on gameplay and how to win see the links below the post.

By chance I discovered a maemo package for vultures eye which I installed on my Nokia N810. Vultures eye is a nice graphical frontend for nethack.

Which dragon shall I ride? - Vultureseye on the N810

Then I felt it would be nice to have Vultures Eye also on my PC. With a large screen and real mouse/keyboard input the game is easier to play, than on the small n810s touchscreen. Since the latest available Gentoo ebuild was far out of date and the sources for it are no longer available I wrote a new ebuild based upon the old one. You may download my new ebuild from here: vultures ebuild (1103)

To use the ebuild it just copy it to /usr/local/portage/games-roguelike/vultures/. You probably have to create the directory. Then run

ebuild /usr/local/portage/games-roguelike/vultures/vultures-2.2.100.ebuild digest

Be sure to include the following line in your /etc/make.conf.

PORTDIR_OVERLAY=”/usr/local/portage”

Then just emerge vultures and enjoy many YASDs. But beware, one can get quite addicted to this game.

FlightGEAR 2.0.0 on GENTOO

I have searched for a 3D game on Linux and found this nice flight simulation. In Gentoos portage tree there is only an old version avaiable, so I wrote an ebuild for the new version. It compiles fine on my computer wth 64bit Gentoo – Linux.

The Power of my graphics board (nVidia Corporation Quadro FX 360M) seems to be enough for this simulation. The control is not easy, but with some time, you can fly around, like in a real aircraft.

What is FlightGear?
The FlightGear flight simulator project is an open-source, multi-platform, cooperative flight simulator development project. Source code for the entire project is available and licensed under the GNU General Public License.

HowTo install on Gentoo:

Download FlightGear ebuild (948) file which include the ebuilds

cd /usr/locale/portage
tar -xzpvf ~/flightgear-2.0.0.tar.gz

Then you have to unmask the ebuilds in /etc/portage/package.keywords :
=games-simulation/flightgear-2.0.0 **
=dev-games/simgear-2.0.0 **
=dev-libs/boost-1.37.0-r1 **
=dev-util/boost-build-1.37.0 **
=media-libs/freeglut-2.6.0  **

now you can ’emerge =games-simulation/flightgear-2.0.0′

Have fun

UPDATE 04.03.2010:

Now it´s in portage, with two different lines. First of all I found out that freeglut 2.6 is needed for flightgear, so I put it in the ebuild. And the second is a patch witch is needed if you don´t use freeglut 2.6. So I think my choice is the better way.
