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-2.0.0-stereoscopic_overlay.tar.gz (2957 downloads ) file which include the ebuilds

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

After upgrading my system from libsmbios-2.0.3 to libsmbios-2.2.19 my scripts for setting up wireless failed. After a short search on dell linux wiki I found out, that some Scripts have got a new name. So dellWirelessctl is now smbios-wireless-ctl. The usage seems to be the same.

What is libsmbios?

It is a cross OS library intended to be used to obtain common information available in BIOS using a unified API. Currently, it can programmatically access any information in the SMBIOS tables. It also has the ability to obtain Dell system-specific information such as the Dell System ID number, service tag, and asset tag. Future plans include APIs for $PIR, and mptable mapping.

If you want to know more about libsmbios, have a look at http://linux.dell.com/libsmbios/main/cmdlinetools.html

I hope this information is useful for you

best regards

Thorsten

Today I found this petition for Gimp. Have a look and support gimp. It seems that gimp should be removed from the next ubuntu release. There for have a look at Bring Out The Gimp petition. Below is a copy from this site. Now Sign the Petition and stay tuned.

To:  GNU/Linux major distributions

We, the undersigned, kindly ask all major distributions not to cripple their release CD’s by removing important applications like OpenOffice.org, GIMP, and others.

These applications may have their set of problems. Granted. Let’s work on them as well.

However, removing such important applications in order to save space for any “current trendy application” just because said application depends on bloated, problematic and polemic runtime environments reveals a worrysome mindset: form over substance.

If the functionality said application provides, is also provided by another application which is far leaner, then please fix the problems with the leaner applications rather than removing important applications such as The GIMP.

Sincerely,

The Undersigned

From Linus:

Ok, there’s just a few final commits since -rc9 to fix a couple of last regressions and problems, and now the final 2.6.31 is out there. The small diffstat and shortlog is below, the full log and diff from 2.6.30 are being uploaded to kernel.org (and then mirrored out) as I write this. In general, the full set of 2.6.30->31 changes are too numerous to list, but as usual, you’ll find some high-level overviews on kernelnewbies.org. read more

We will inform you if zen-sources are avaiable and running.

For one of our projects I had to write a simple program, for importing items into our online store (watercoolshop.de). When I finished the coding everything seemed to run smooth, but only on Windows. Afterwards I tested the program on my linux box and it did not work.

After checking all files I found out that the encoding of the files was wrong for importing into our shop. With the help of google and some other sites the problem was solved. I had to use ISO-8859-1 for all files, because the core data is 8859.

To read a file I use the following code now:

BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream(),”ISO-8859-1″));

and to write:

Writer bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(fileName), “ISO-8859-1”));

I hope this will help someone who has a similar problem.

Thorsten

As you can read here 2.6.30 is out now. As to the whole set of changes since 2.6.29, the best place to look is probably just
http://kernelnewbies.org/Linux_2_6_30
as usual. One thing that doesn’t seem to be mentioned here is that we’re hopefully now done with the suspend/resume irq re-architecting, and have switched to a new world order. Although I suspect lots of details will still change, of course.

If we have tested the new kernel, probably with zen patch set, we will tell you

After I have tested the nvidia-drivers-185.18.08 beta I searched the web for a new one and I found it yesterday on nvnews.net. This version seems to run well on my Dell M4300. For all using Gentoo I  made an ebuild: ebuild:nvidia-drivers (1466 downloads )

# mkdir /usr/local/portage/
# cd /usr/local/portage/
# tar -xpvf nv-portage.tar

Be sure that PORTDIR_OVERLAY=”/usr/local/portage” is in your /etc/make.conf, then you can emerge it:
# ACCEPT_KEYWORDS=”~amd64″ emerge =nvidia-drivers-180.60 -1
