You can use it as a clue to mount your partition. fdisk also list the device name of the corresponding partition thus making your job easier to identify which device contains the data that you want to find.

Burn CD images in Linux command line

This tip will be brief, it concerns about writing bootable linux iso images to CDROM. What you need is cdrecord, cd-writer drive, blank cd-r and iso image (and maybe mkisofs).

Howto burn ISO images to CD
Insert the blank CD-R, and run

cdrecord -v speed=4 dev=/dev/cdrom ubuntu-6.10-desktop-i386.iso

and you’re done.

Howto burn (backup) files to Data CD
You’ll need mkisofs and cdrecord to burn your data files to a CD,

Run,

mkisofs -r -J -o yourbackup.iso /home/path_to/your_files

cdrecord -v dev=/dev/cdrom  -data  yourbackup.iso

and that’s the easiest way to burn cds on command-line linux.

Optimise your openoffice files with KJar

Hi, I found a way to optimise the size of OpenOffice.org files. The OpenOffice.org file format (*.odt, *.odp, *.sxw, etc) uses series of xml files to describe the content of documents. These files are package into a JAR file (similar with zip file format) which uses deflate compression algorithm.

Though OpenOffice.org files are relatively small, it is interesting that you can make the file even smaller by recompressing the documents file using a better optimized deflate implementation.

One such implementation are made by Igor Pavlov for his 7zip application, which is used by AdvanceMAME to create a suite of application,AdvanceCOMP to recompress deflated files. However this implementation are not coded to handle the zip file variant (JAR) used by OpenOffice.org.

One alternative is to use the KJar recompressor which uses Ken Silverman deflate implementation (kzip/kunzip). The application itself is non-free and only available as Win32 binary (*.exe), however it can be adapted for use with wine.

How to compress OpenOffice.org files?

Simple, just rename your document file to .jar, and run kjar on it. The process will take a while and on average I’m able so save up to 15% -40% openoffice file size, which is about 60KB for 500KB OpenOffice file. My record is able to save 54% of the original filesize (from 1354KB to 420KB), that’s a lot of saving there.

Maybe some of you think that this is unimportant, but as for me, i’m always interested in how much space that I can squeeze on a 500+ page documents :)

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
