"Sintel premiere" by Blender 3D Team

The last project named "Sintel" is better than expected .
I watched all projects and this  is one of the best.

A new update for "SEO Starter Guide".

Google say us:
"About two years ago we published our first SEO Starter Guide, which we have since translated into 40 languages..." The new version is more explicit and useful to have it.
Unfortunately, it is not translated in all languages.
I wonder why Google does not use the open source community to translate them.
Now we can download the new update from here.

Python, pyuno and OpenOffice

Some time ago, I discovered Python. Then I saw that he can work with the OpenOffice.
Today I will briefly introduce how to do this. I do this in Windows XP, and Windows users could benefit.
In the folder : C:\Program Files\OpenOffice.org 3\program there was a file called python.exe.
Go there and type the following script to start OpenOffice:

import os
import subprocess
import sys
import time
import uno

NoConnectionException = uno.getClass("com.sun.star.connection.NoConnectException")
ooffice = 'soffice "-accept=socket,host=localhost,port=8100;urp;"'
def start_OOo():
    '''Starts OpenOffice.org with a listening socket.'''
    # Start OpenOffice.org and report any errors that
    # occur.
    try:
        retcode = subprocess.call(ooffice, shell=True)
        if retcode < 0:
            print >>sys.stderr, \
                "OOo was terminated by signal", \
                -retcode
        elif retcode > 0:
            print >>sys.stderr, \
                "OOo returned", \
                retcode
    except OSError, e:
        print >>sys.stderr, "Execution failed:", e
    # Terminate this process when OOo has closed.
    raise SystemExit()
started_OOo = False
if not started_OOo:
    print "Starting OOo"
    started_OOo = True
    start_OOo()
time.sleep(3)
print "OOo started"

This will start OpenOffice 3.
We can use now python scripts to create any type of file used by OpenOffice.
Let show one image create with few lines :

My linux counter machine

The Linux Counter website is a good site to share your machine's info.

At Sep 02 2010 16:22:56 GMT, there are
125104
users registered
133701
machines registered
My guess at the number of Linux users:
Twenty-nine million 

My number machine is :

We can use a script to registers or updates a machine's info in the counter.
The script allows here.
We can use add, update and send mail with info about your Linux machine.
We can add a crontab job with -c arg.
The user ID must only be able to send mail and write to its own home directory.

Create html file with bash script using awk

We will present a more special method of using the Linux command line.
This method comes in helping those who need to text or HTML content.
In fact, a combination of Linux commands to get an output.
Suppose we have a list of jpeg files in folder image.
They should exist into HTML to be displayed.
As we know an image has the form:

<img src="image/name_of_jpeg.jpg" alt="" /> 

The list of file is :

11.jpg,12.jpg,13.jpg,14.jpg,15.jpg

My method uses two commands: ll and awk.
First, I will display files:

$ ll | awk '/jpg/ {print $9}'
11.jpg
12.jpg
13.jpg
14.jpg
15.jpg 

I created one variable f1.
In these variables put the beginning of each line:

f1=‘<img src="image‘; 

We add two sed commands.
First, remove the space before the file name.
The second will add the rest to complete the link.
The xargs command is used with echo and print the first part of the link.
Finally we use <<< aaaa.html to output the HTML file.
The full script is here .

OpenGL - OpenGL Utility Toolkit (GLUT) on Fedora 13

The freeglut allows the user to create and manage windows containing OpenGL contexts.
This library allows the user to use mouse, keyboard and joystick functions.

Frogatto new game crossplatform...

A new game is very nice and interesting. Named "Frogatto", this game should replace some older games from gnome.
Frogatto is freely available for Mac, Windows, and Linux.
Download it.

Sunflow rendering on Fedora 13

How to install Sunflow ?
It's pretty simple. Download the zip archive from here.
Unzip and edit the sh script sunflow.sh
from the sunflow folder.
By default the script is :

#/bin/sh

mem=1G

java -Xmx$mem -server -jar sunflow.jar $*

If we run this script will have this error :

$ sh sunflow.sh 
Invalid maximum heap size: -Xmx1G
Could not create the Java virtual machine.

The solution is:

$ whereis java
java: /usr/bin/java ...

Now change the script :

#!/bin/bash
/usr/bin/java -Xmx1024M -server -jar sunflow.jar $*

And run it ...

$ sh sunflow.sh 

The result is :

Makehuman 3D on Fedora

Makehuman software installation is simple. You must be superuser, and then use yum:

$su
#yum search mhgui
#yum install mhgui.i686
#yum search makehuman
#yum install makehuman.i686  

It will automatically install animorph-0.3-6.fc12.i686.
A negative aspect of Fedora 13 is the lack of 3D software: Moonlight, Sunflow, Blender 2.5 or Loki Render
It looks like 3D graphics programs are not a priority.

Fedora 13, FX 5200 and Yo Frankie!

Today I tried to run game "Yo Frankie."
The computer used in this case is older.
It has an FX 5200 video card with 1Gb RAM and processor ASUS motherboard.
I was not expecting a success but he did seem somewhat.
Here are some pictures:



In the "Options" I set no shaders
I must say that without activating the button "Maximize" will not be able to get to the "Back" from "Option".
The operating system is undoubtedly Fedora 13 with default graphics drivers.

New tutorial about Eclipse.

I just finished a new tutorial.

About my name ...

My name often poses difficulties for Americans.
CĂTĂLIN = Romanian masculine form of KATHERINE.
Pronunciation of CĂTĂLIN:

The surname is of Dacian origin.
My nickname is a combination.
And mean sum of myth from mythical and cat from Catalin or cat.
About KATHERINE
Pronounced: KATH-ə-rin, KATH-rin
From the Greek name Αικατερινη (Aikaterine). The etymology is debated: it could derive from the earlier Greek name ‘Εκατερινη (Hekaterine), which came from ‘εκατερος (hekateros) "each of the two"; it could derive from the name of the goddess HECATE; it could be related to Greek αικια (aikia) "torture"; or it could be from a Coptic name meaning "my consecration of your name". In the early Christian era it became associated with Greek καθαρος (katharos) "pure", and the Latin spelling was changed from Katerina to Katharina to reflect this.

The name was borne a semi-legendary 4th-century saint and martyr from Alexandria who was tortured on a spiked wheel. The saint was initially venerated in Syria, and the name was introduced to Western Europe by returning crusaders. It has been common in England since the 12th century in many different spellings, with Katherine and Catherine becoming standard in the later Middle Ages.

Famous bearers of the name include Catherine of Siena, a 14th-century mystic, and Catherine de' Medici, a 16th-century French queen. It was also borne by three of Henry VIII's wives, including Katherine of Aragon, and by two empresses of Russia, including Catherine the Great.

Fedora 14 - next wallpaper concept

The new concept of wallpaper on which I worked.
I used Blender 3D. Rendering time was short, less than 2 min.
This is because I used some tricks.
It seems more appropriate for a wallpaper.
