        01/15/08
        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:

        Saving this for a later read

        Seems like a good article, I feel too tired to read at the moment :P, I'll just post the link here for now:

      • Hardware Vs Software Firewalls: Out of the Blue
        01/13/08
        Just out of the blue, this came up ;) - I decided to search for articles comparing hardware and software firewalls

        Source 1: http://www.smallbusinesscomputing.com/w

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

        Summarizing it:

      • System Monitoring: in Linux
        01/13/08
        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:

        Excellent and simple guide: http://ubuntuforums.org/showthread.php?t=518293

        I am tempted to put the whole post up here...but may be a little big :P

        vsftpd itself is also nice and simple

      • Uninstalling: in Linux (Debian)
        01/13/08
        This is using apt. I thought I'd post this, in the case I ever did this mistake (of deleting config files by hand)

        Good stuff...though it says Red Hat, I would guess its applicable to most Linux distros (except nmap may have to be installed for distros where it does not come by default)

        Basic Idea:

        - Use nmap to portscan the lo

      • REGEX: In Linux and More!
        01/12/08
        Recently, working on a programming project, I had to do some string pattern matching. From prior experience, I knew "regex" was the perfect candidate. But the problem was, I was unfamiliar with it, and in the past have always relied on internet for help :)

        01/12/08
        Wow...almost 2 months since my last post. I guess I got carried away by life :P

        After some thought, I figured I'd use the desktop at home thats doing nothing as a server (I've done this before, but this time I wanted to make it permanent).
