Angstrom/OpenEmbedded Linux running on PS3 Slim

Its been long since I updated my blog.

I have used openembedded/Angstrom to build the filesystem. Added few of my own configs to the org.openembedded.dev to support powerpc64 ARCH and optimizations for cell processor.
I am using AsbestOS method of loading kernel.

Here are the YouTube Links:

I will upload the binaries soon.

Adding proxy support for chromiumos build

Its been very long since i updated my blog, lately i have been very busy with lots of things.
I recently had a look at ChromiumOS build and observed that it doesn't take my env proxy settings. If someone is facing the same problem u can add the following lines at the appropriate locations. The first patch is to add proxy support to the user created in chroot and the second patch tell sudo command to use the current proxy env variables instead of resetting them.
------------------------------------------------------------------------------------------
bash_chroot "echo $USER ALL=NOPASSWD: ALL >> /etc/sudoers"
# add proxy support for chromium os build
bash_chroot "echo Defaults env_keep += \"http_proxy https_proxy ftp_proxy no_proxy\" >> /etc/sudoers"
# end
bash_chroot chmod 0440 /etc/sudoers
------------------------------------------------------------------------------------------
>> "$FLAGS_chroot/home/$USER/.bash_profile"
done

# add proxy support for chromium os build
echo "export http_proxy=\"$http_proxy\"" >> "$FLAGS_chroot/home/$USER/.bash_profile"
echo "export https_proxy=\"$https_proxy\"" >> "$FLAGS_chroot/home/$USER/.bash_profile"
echo "export ftp_proxy=\"$ftp_proxy\"" >> "$FLAGS_chroot/home/$USER/.bash_profile"
# end

if [[ "$USER" = "chrome-bot" ]]; then

I am yet to successfully build a working image and run it.

Medical Image Analysis Projects

The Project is uploaded at
http://medimganalysis.sourceforge.net/
Place to upload my course materials and codes i have written.
I choose to write the programs in qt, which is a cross platform library (s60, linux, win, mac, embedded linux, windows ce).

"GRE Words" My First J2ME Application :D

Hi guys, it has been very long time since i updated my blog. I have been very busy lately anyway
I wrote this small j2me application using netbeans IDE to help me prepare for GRE :D.
[Its not my own idea] there many apps out there. Thought i would make one myself :P. Im sharing it, and i hope someone might find it useful.
If you don't like the words bundles with the application. U can edit "words.txt" file in the jar and put your own words file in that format.

u can download from:

QtDownloadManager

- A Frontend download manager for linux commandline accelerators.

I haven't found any good gui download accelerator. And i frequently use axel with firefox and its pain to have many windows opened at a time. And i have to save the url somewhere if i want to pause and restart the url later.
So i thought of making my own :D .I have written the program in Qt4.
My idea was to have a common GUI for most of the command line accelerators available for linux like
1) axel
2) proz
3) wget etc ......
I have integrated axel till now; Others are yet to be done.

Its not yet ready for a release, I have been working on it only for last 5 days.
As It is written in qt4, it can be used on all three major platforms,
Linux, Mac and Windows (might require cygwin for axel).

Here is a quick overview of how it looks.

Finally a working gtalk voip in linux !!!!!

I have been browsing through net and came across this post
http://alex.eftimie.ro/2008/11/18/howto-gmail-voice-and-video-chat-on-ubuntu-linux/
I have tried jabber and other gtalk voip clients for linux that are said to be working , and nothing actually worked for me. I was bored and thought i would give the above method a shot (thinking that it would end the same as before). Surprisingly it worked :), for the first time i was able to call a gtalk user and do voice chat from linux :) althought video doesn't work.
However im still using pidgin and occationally switch when voip is necessary. And i already gave up on google to release gtalk linux native.

Opencv on Beagleaboard !

I tested opencv on beagleboard for onboard image processing. The examples provides with opencv runs fine , but the performance is poor compared to a PC.

BeagleBoard (OMAP 3530, ARM Cortex-A8 600MHz, 128MB ram)
PC (Intel core2duo 2.13GHz, 1GB ram)

It took me about 4.4 sec on beagle for a simple facedetect example to detect all faces and around 0.35 sec on PC
