123456, cea mai populara parola
O grava eroare de securitate la RockYou.com a condus la publicarea a 32 de milioane de parole. Compania de securitate Imperva Application Defense Center a analizat distributia acestora si a ajuns la concluzia ca cei mai multi utilizatori aleg parole foarte simple.
Conform studiului, aproape o treime dintre utilizatori aleg parole cu lungime de sase caractere sau mai putin. Aproape jumatate dintre utilizatori folosesc prenume, cuvinte uzuale si parole nesigure (secvente de cifre sau litere pozitionate adiacent pe tastatura). Cea mai frecventa parola a fost 123456.
Iata cele mai populare 20 de parole de pe RockYou.com.

Aliens vs Predator, cerinte minime
SEGA a dat publicitatii cerintele minime si recomandate de sistem pentru FPS-ul Aliens vs. Predator. First Person Shooter-ul Aliens vs Predator va fi lansat atat in varianta PC, cat si in versiuni pentru PS3 si Xbox 360, in 19 februarie 2010, insa varianta PC va fi mai avansata decat cele pentru console multumita utilizarii API-ului DirectX 11.
"Versiunea de PC a lui AvP foloseste la maximum optiunile oferite de cele mai noi placi video si este optimizata pentru a utiliza eficient multicore threading, daca PC-ul respectiv are o astfel de functie", a declarat David Brickley, senior producer la Rebellion, compania care lucreaza la jocul Aliens vs Predator. "De asemenea, vom oferi unul dintre primele jocuri care demonstreaza cat de bine poate arata grafica sub DirectX 11 - modelele Alien utilizeaza hardware tessellation si displacement mapping, precum si Shader Model 5.0 pentru efecte de postprocesare."
Cerintele minime sunt:
- Windows 7/ XP/Vista
- 3.2 GHz Intel Pentium 4/Athlon 64 3000+ or equivalent processor
- 1 GB System RAM (XP)/ 2 GB System RAM (Vista)
- DirectX 9.0c compliant video card with 128 MB RAM (NVIDIA 6600 or better, ATI X1600 or better)

Mandriva 2010 Free
One more note before we get down to business, all procedures i will suggest here require an active network connection. These are procedures that work for me. I have tested them many times. I have set up my desktop the way i need it. I would highly recommend that you set up sudo which will make all these commands work effortlessly - Part 2, Post-install Mandriva::2010.0 set up 'sudo'
A word to the wise from the dumb - backup your stuff regularly.
Ok here goes... I like to remove the CD/DVD as a source. But this step
1. Remove all media, can be skipped.
copy and paste this into a terminal,
2. Add Media Sources
Mandriva 2010.0: i586 (32-bit), use command procedure 32bitMDV, 32bitPLF, and 32bitMIB
32bitMDV more info
copy and paste this into a terminal,
32bitPLF more info
enter this into a terminal
32bitMIB more info
enter this into a terminal
If you have just done the 32bitMDV, 32bitPLF and 32bitMIB commands then skip this section
This is ONLY for Mandriva 2010.0: x86_64 (64-bit). To add media sources (software repos) to a 64bit Mandriva installation, complete the 64bitMDV 64bitPLF and 64bitMIB procedures
64bitMDV more info
enter this in a terminal
64bitPLF more info
enter this into a terminal
64bitMIB more info
enter this into a terminal
hit [enter] wait ...
3. Update media sources (repositories)
4. Best audio device control
5. Lightweight Music player
6. Ear and eye candy
7. Video Lan Client
8. Gstreamer
9. Xine
10. MPlayer
11. DVD's, and more
12. Java
13. Adobe Flashplayer
14. Communication Central I still can't get everyone to use Ekiga
Now.. it's all done. You might want to restart your browser to activate the new flashplugin. I hope it works for you. Mandriva is the perfect desktop. My next post is in the festive spirit - it deals with candy, with compiz fusion and emerald. I'm no expert but mine works.

Mandriva Media Sources (repositories) explained
The Official Mandriva Wiki::
The Mandriva Linux ftp mirrors for final release versions contain at least:
* main which contains most important programs, supported by Mandriva
* contrib which contains some more optional programs added by contributors, but which do not necessarily get (security) updates
* non-free which contains some programs which are not free
Each media has 4 sub-medias:
* release the packages as of the release day.
* updates the packages updated since the release day for security or bug concerns. Everyone should have this medium, even with a very slow internet connection. When adding an update medium, add the --update switch so urpmi can distinguish it from a regular medium.
* backports some packages of new versions backported from cooker.
* testing which is used to temporary tests of new updates, to allow the bug reporters to validate the corrections.
*Cooker is the future release of Mandriva before it becomes official (new stable version).
