Fighting Blender, NVIDIA and GNOME ...

Today I spent some time with Blender, NVIDIA and GNOME ...
Since I did pre-update and put Fedora 15, the system worked well until today.
Today I tried to relax a bit with Blender 3D, but ...
[free-tutorials@user ~]$blender
Info: Config directory with "startup.blend" file not found.
Segmentation fault (core dumped)
How to prevent uploading that file? Simply using:
[free-tutorials@user ~]$blender --factory-startup 
Segmentation fault (core dumped)
Obviously, I should try to debug:
[free-tutorials@user ~]$blender --factory-startup  -d
Blender 2.57 (sub 0)
Build: 2011-04-27 16:56:56 Linux:32bit Release
argv[0] = blender
argv[1] = --factory-startup
argv[2] = -d
read file 
  Version 256 sub 6 svn r36063

ordered
 OBCube
 OBLamp
 OBCamera
Segmentation fault (core dumped)
Simply don't want, it's something related to graphics card ...
[free-tutorials@user ~]$blender --factory-startup  -d -noglsl 
Blender 2.57 (sub 0)
Build: 2011-04-27 16:56:56 Linux:32bit Release
argv[0] = blender
argv[1] = --factory-startup
argv[2] = -d
argv[3] = -noglsl
read file 
  Version 256 sub 6 svn r36063

ordered
 OBCube
 OBLamp
 OBCamera
Segmentation fault (core dumped)
So the problem is not related to GLSL.
Then I tried to see what glxinfo says.
[free-tutorials@user ~]$glxinfo | grep Error
Error: glXCreateContext failed
I found this problem and I added to xorg.conf the following lines of code.
Section "Files"
ModulePath "/usr/lib/xorg/modules/extensions/nvidia"
ModulePath "/usr/lib/xorg/modules/drivers"
ModulePath "/usr/lib/xorg/modules"
EndSection 
I must admit that after restarting the computer, greeted me with the gnome interface and unprecedented special effects.
Then I waited ... and waited ... I fixed up with a simple line of code:
$  gsettings set org.gnome.desktop.session session-name 'gnome-fallback'
... written in Xfce terminal, because in gnome I have not succeeded.
Now I have the old gnome, slightly improved but it works flawlessly with Blender 3D...

News: "A tour of Eclipse Helios" by IBM

It's a pretty good and complete information about Helios ...
Article begins:
Helios is the simultaneous release of 39 Eclipse projects. In terms of statistics, the Helios release includes 33 million lines of code developed by about 500 Eclipse.org committers from 44 companies...
You can read here and you will be impressed by the new Helios.
The best part for Linux users is Linux tools.
As Andrew Overholt says in the same article:
"The Linux Tools project also aims to increase the amount of Eclipse technology available in Linux distributions. We are working towards this goal by providing a build harness of the Eclipse SDK that is easy to consume for Linux distributions and already have a number of distribution consumers."
I have not yet found the negative aspects from the Helios ...

What things should be fixed quickly ?

Here are some things that should be repaired.
There are minor things or less, but make life a misery. There are things that generate more questions and more errors on the Internet.
This is an epidemic of questions there just because they are not repaired.

1. Google must give the possibility to download video files updated...
2. Python modules gdata do not work for all versions... ( and many modules has the same problem)
3. Python module ftplib does not know about SFTP, just FTP
4. Too many compilers for C and C + + and lack of advanced tutorials for setting them, especially gcc on windows
5. Social networks Spam filling our mail.


I will try to update the list over time.
I'm sure there are more ...

The word "includ" generates error in gmail.

I accidentally discovered an error.
I sent feedback to Google, I hope to resolve quickly.
The problem is with the word "include" is a word used in the Romanian language and means "include".
Because of this, I can not send emails it contains, Gmail asking to "include file"

The discovery of an ancient ancestors linux ...

Who says penguins are weak?
Linux is a good system if it is used by smart people.
Since ancient times people are born with penguins.
It seems that dinosaurs could not survive, but the Penguins have managed well.
They became smaller but everyone loves them.
Whether they are small and fast as Gentoo, or slower ... we are glad that we have no windows open.

Nokia SDK and MIDlet

Yesterday I played with the SDK from Nokia. Do you think that it's easy to create a MIDlet?
Finally, I managed to make an application "Hello World'.
Maybe I'll write a little tutorial in the near future when I'll know more about MIDlets and java.
Here is the resulting feedback.

Blender 3D and F14 killed by "Save as"

Although he reached the 2.55 beta, Fedora 14 is still struggling with version 2.49b.
Not bad if it goes, but here's one little problem
It's all well and good until the "Save as".
Then it breaks and you have just this reason:
Process /usr/bin/blender.bin was killed by signal 6 (SIGABRT)
