tremulous – addictive open source FPS game

These past few days I’ve been hooked up playing Tremulous, an open source First Person Shooter (FPS) game. The objective of the game is to protect your team’s base and eliminate the enemy base. You can choose one of the two sides, either as member of human team or as an alien species.

Each side has it own unique abilities; the humans have long-range weaponry and the aliens have powerful melee attack and high body hitpoints The game uses GNU/GPL Quake III engine and only requires modest 3D hardware acceleration.

Tremulous is indeed a fun and addictive game, those who want play tremulous with me can look me up in Tremulous Basic Server #1 through #3 (low pings for me).

Download tremulous at : http://tremulous.net available for Windows and GNU/Linux operating system

Photorec – Recover files from corrupted Hard Disk (filesystem) with Linux

Today I want to introduce you to Photorec, one of the open source data recovery software available in Linux. Photorec was designed to recover lost files including video, documents and archives from Hard Disks,CDRom and lost photos from Digital camera memory card.

Originally written to recover lost pictures (hence the name), PhotoRec now supports recovering more than 80 files types including zip, bz2, rar, 7z tar, microsoft office files (*.doc,*.ppt, *.xls), jpg, pdf, html, midi,mp3,wav and many more.

PhotoRec ignores filesystems and read raw data directly from block devices, this makes Photorec works well with various filesystem including fat32,fat16,HFS+, NTFS, ext2/3.

PhotoRec is known to not work very well with ReiserFS however.

Here’s the screenshot of PhotoRec in action (which i uses it to test my corrupted MMC) :

From the screenshot, you can see that PhotoRec is able to recover 263 files from my MMC.

PhotoRec is safe to use, it will never attempt to write to the drive or memory support you are about to recover lost data from. All recovered file is stored in your /home directory and not withing the recovered disk itself, thus preserving the data contained within it.

For ubuntu users, you may find PhotoRec listed under the ‘testdisk’ package in Universe repository.

You can find out more about PhotoRec and testdisk at : http://www.cgsecurity.org/wiki/PhotoRec
