Nifty Tricks !

Trick 1:Running a simple HTTP / FILE server:

Supposing you have a folder where you have mirrored a repository and now want to use it instead of the on line (Over the Internet) repo.
So, since most Linux…et all OS es have PYTHON by default ,

cd to the mirror folder and execute
$python -m SimpleHTTPServer 9914
NOTE:here 9914 is an arbitrary port number, can be any unused port.

Trick 2:Resuming Torrent Downloads:
Recently because of some reason my ubuntu 8.10 which i was using for a long time, crashed. I had lots of unfinished torrent downloads there.
Not knowing what to do, i took a copy of the incomplete downloads and headed over to 9.04 and then copied them to Transmission Torrent client’s default download location and downloaded the same torrent files, to my amazement the
downloads resumed !

The UI of the Future

The 10/GUI desktop UI is quite good though not revolutionary (Already existing on mobile phones)
Here is a brief preview of the concept.

10/GUI from C. Miller on Vimeo.

Just got My 9600GT & Corsair SMPS.

I recently got my 9600GT along with a 450W Corsair SMPS and they are sweeeet !
Though i am very excited with my new toys here are a few preliminary observations about them:
1.The SMPS has got no fan and so makes ZERO noise.
2.The glxgears in my ubuntu 8.10 box maxed at 8700FPS in contrast to 1200FPS of the built in ATIx1250 Graphics Card.
3.The card comes with a cable to connect to my TV (That’s neat !).
4.The Nvidia drivers for Ubuntu are so good that they pointed out that i had not connected a power cable to my Graphics card :-p (Man this is good !!!).

For now i just feel like getting submerged in the millions of colors and realistic virtual worlds fed by the juice of my Graphics Card.
Haaaaaaaaah !

Database Project

The DB Design

We were asked by our Database professor to design and implement a Database for storing details of Practical Exams of our Department as a Mini-Project.
Though we were not given any particular goal, with this design of mine i aim to write an application which will generate the time table given a start date of the Practicals.
I have made following “Application” Design Decisions in this draft (Random Order):
1.Alternate semesters can have labs simultaneously.
2.Clash of Dates ,ie student’s regular and arrears are scheduled on the same day at the same time, are avoided by scheduling the Pracs of higher semesters first.
3.Some labs are subject specific. i.e. we should have Analog Electronics Prac only in a particular lab.

Thats all for this Draft.
