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)

I searched my computer the lib libstdc++, see below :

# yum search libstdc++
Loaded plugins: langpacks, presto, refresh-packagekit
Adding en_US to language list

The archive named gDEBugger57-i386-cpp3.tar.gz has 13Mb.
Then I use commands :

$gzip -dc gDEBugger57-i386-cpp3.tar.gz | tar xf -
$ cd gDEBugger57-i386-cpp3
$ su 
# yum install compat-libstdc++-33.i686 

The gDEBugger run well under fedora 14 , but is free only 7 days. See below:

Fakeroot and Yum

It seems that the yum and fakeroot do not get along too well.
I did not understand why ... Here is output:

Fedora 14 and NVIDIA FX5200

Today I set video driver on Fedora 14.
I have an FX5200 and I use akmod to make this working.
First when I install akmod with :

yum install kmod-nvidia-173xx-2.6.35.6-48.fc14.i686.PAE.i686

I have some errors:

$ glxinfo | grep direct

Xlib:  extension "GLX" missing on display ":0.0".

But i solve and Savage XR working well :

Fedora 14 versus 3D software .

In the next few days ago I decided to try software 3d with Fedora 14.
I am disappointed again. I was expecting some improvements in this area by the developers.
Especially because it is a difficult topic.
But let's see why I have this impression...
I have searched for packages that are required with this command:

# yum search "3d engine"
...
============================== Matched: 3d engine ==============================
irrlicht.i686 : A high performance realtime 3D engine
crystalspace.i686 : Crystal Space a free 3D engine
ember.i686 : 3D client for WorldForge
ogre.i686 : Object-Oriented Graphics Rendering Engine

Code:: Blocks does not work with Ogre 3D or Irrlicht 3D packages. Although I spent quite a long time. However, on Windows XP this combination worked well.
Ember game working hard. Maybe because my video card - FX5200, not really likes the new drivers.
Code:: Blocks is very stubborn. Ogre and Irrlicht Wizards of the Linux version of Code:: Blocks does not work at all.

Fun with F-Spot 0.8.0 and sqlite3

Today I focused on the F-Spot version 0.8.0.
I knew that contains a database that keeps information about the pictures.
I found the database and tried a few commands:

$ cd .config/
$ cd f-spot/
$ ls
addin-db-001  photos.db

Once I found the database, I started SQLite3. See the example below:

$ sqlite3  photos.db 
SQLite version 3.7.2
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> .tables
exports         meta            photo_versions  rolls         
jobs            photo_tags      photos          tags          
sqlite> .schema photos
CREATE TABLE photos (
 id   INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, 
 time   INTEGER NOT NULL, 
 base_uri  STRING NOT NULL, 
 filename  STRING NOT NULL, 
 description  TEXT NOT NULL, 
 roll_id   INTEGER NOT NULL, 
 default_version_id INTEGER NOT NULL, 
 rating   INTEGER NULL 
);
CREATE INDEX idx_photos_roll_id ON photos(roll_id);
sqlite> select * from photos;

It is easy to use and implemented various python scripts.

Notifications in Fedora 14

We use the following command

$ notify-send  "This is some text"

or

$zenity --info --text "This is some text"

This will display a text balloon "This is some text".
The problem appears when we want to display the output of a command.
For this, I used a python script. Here's the source code:

#!/usr/bin/env python
import os
import sys
import pynotify
pynotify.init("Output comand")
arg=sys.argv[1]
print arg
s = os.popen(arg).read()
n = pynotify.Notification("Output",s)
n.show()

If you wish to use a compound command, then you will need to use quotes.
For example, we use the command "ls-a 'as follows:

$python testpy.py "ls -a"

This is just a small example, you can create more complex applications.

Fedora 14 and Blender 3D

It is a great disappointment to me that Fedora 14 comes with Blender 3D version 2.49b-10.
I expected a pleasant surprise to see version 2.5.
