        06/05/08
        To any reader of this blog, I have changed the main site and have created 2 new blogs - personal and tech (and I am discontinuing this one). Please visit the home page at http://www.ai-projects.info/. The link to the new blogs may be found there.

        04/05/08
        I am pretty happy and surprised, that a lot of the blog posts are being rated now (hence read, I believe!). I would appreciate anyone reading to post some comment in addition to the rating (this way I know how I can improve post quality).

        It has been a little busy. But after April 12, 200

        03/14/08
        From now on, I am going to drop the prefix AONTW, since I think it has served its purpose - to make me post regularly :)

        Recently, I was thinking of building an issue tracker. One of the features I thought would be cool to have, was to see previous issues related to the current issue (it

        03/04/08
        I was looking into the TEA (Tiny Encryption Algorithm) article in Wikipedia. It mentioned about Fiestel Ciphers, which I have found out is a type of block cipher. Here I will share my findings:

        I have had interest in cryptography, and have lightly scratched the top of its surface many times in the past. So, I thought I'd be a bit more focussed and do something this time (the inspiration to do this again, probably came from reading Digital F

        Lets see how long I keep this up... :)
        I think I'll post something new I learned every week (mostly weekends). Here goes the first. This is about Video Encoding. Here are somethings I learned in the process of research.

        I started searching about Business Intelligence...this slowly led to other things...one of which, was data warehousing. I have quoted one part from Wikipedia, which I found easy to understand:

        Just out of the blue, this came up ;) - I decided to search for articles comparing hardware and software firewalls

        This is a good article that compares hardware firewalls and software firewalls...

        Ah...system Monitoring, it is pretty important...being used to the good old Ctrl+Alt+Del in Windows (or Ctrl+Shift+Esc), I was somewhat clueless stuck in the command prompt in Linux. After some searching, here are some useful commands I found:
