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)

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:
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.

Linux and denial of service - DoS
A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users.
We can see more on the wiki web page.
On Linux we can see if an attack is attempted with this:
This is an indication of a denial of service (DoS) attack against your system's X port.
It is likely one attack against a public service such as a web server or mail server.

Notifications in Fedora 14
We use the following command
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:
For example, we use the command "ls-a 'as follows:
$ 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.

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:
We can use now python scripts to create any type of file used by OpenOffice.

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:
First, I will display files:
In these variables put the beginning of each line:
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.

java -Xmx$mem -server -jar sunflow.jar $*
If we run this script will have this error :

The solution is:
$ whereis java

Now change the script :

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:
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.
$su

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.

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

This is because I used some tricks.
It seems more appropriate for a wallpaper.

Who needs something, here's how it looks:
from xml.dom import minidom as dom import urllib def fetchPage(url): a = urllib.urlopen(url) return ''.join(a.readlines()) def extract(page): a = dom.parseString(page) item2 = a.getElementsByTagName('SendingDate')[0].firstChild.wholeText print "DATA ",item2 item = a.getElementsByTagName('Cube') for i in item: if i.hasChildNodes() == True: e = i.getElementsByTagName('Rate')[10].firstChild.wholeText d = i.getElementsByTagName('Rate')[26].firstChild.wholeText print "EURO ",e print "DOLAR ",d if __name__=='__main__': page = fetchPage("http://www.bnro.ro/nbrfxrates.xml") extract(page)
That's all.
Parsing files and rename ...
Sometimes you have to rename files.
This can be tiring when we do it manually.
Command "sed" may be helpful in this case.
I'll take a simple example. I will create a working directory called "work."
We have to create files with the command:
The result should be :
Try these commands to parse and rename files:

We have to create files with the command:
for (( i=1; i<10; i++ )); do echo data$i > data[$i]x[$i].txt;done
The result should be :
$ ls data[1]x[1].txt data[3]x[3].txt data[5]x[5].txt data[7]x[7].txt data[9]x[9].txt data[2]x[2].txt data[4]x[4].txt data[6]x[6].txt data[8]x[8].txt
Try these commands to parse and rename files:

"Santa Claus" on Google Map
I wrote on my blog python-catalin.blogspot.com about Google Map and Santa Claus:
I wrote a python module. I called it "geo" because it is a geographic module.
The funny stuff is when i use it with "Santa Claus".
So where is Santa Claus ?!
Google Maps API should be prepared to respond.
Tomorrow a child will know how to use the Python language.
Who knows ...
