The Sound Demon (not daemon) on Linux

I was playing a bengali song on my PC - the rich silky voice of Lopamudra Mitra on XMMS ...
I had built and installed MPlayer some days back.
I thought of just starting a video simultaneously.
As soon I did the following :
mplayer /win1/movies/The\ Matrix/Part1.DAT

Once or twice the video screen came up and then disappeared failing on some count or the other
All the codecs are in place and mplayer install was successful and yet it does not work.
Then the screen came up and remained blank - it neither played video nor audio.
But the XMMS output changed to a strange voice of some man (remember it was playing a female voice a few minutes back)
Then I stopped mplayer and again started and the audio output became even more morphed like the voice of some ghost.
I closed and restarted XMMS but the audio remains like an old ghost/demon - thus came the audio ghost into my system.


CAN YOU DECIPHER THE FOLLOWING OUTPUT OF MPlayer :
Most probably the bitrate or frequency of output of the sound card was reset to some unearthly value by the audio drivers on loading mplayer - hence the ghost !

IIMB PGSEM SOP Essays.

The IIMB PGSEM application for 2008 had a SOP section which required 5 short essays to be written. Here are the ones I had written: Statement of Purpose How do you see the PGSEM helping you in your goals? (150 words) My taking up the PGSEM course has twin objectives, namely, self-development and learning all aspects of setting up, managing a commercial/social enterprise. Having worked in the software industry for five years, I have closely seen the software development life-cycle. However, there are several aspects of business and the economy that are of interest to me and I find the time ripe to explore these in a formal way, through academics; specifically strategic management of a firm, innovation strategies, and the scope of strategic consulting. Getting ready to usher in acceleration in growth opportunities in my care...

Quantum Contrapt - Part 01

First short story in the 'CSlueth files' series.  Note: This is purely a work of fiction! 1. The dead body  Wednesday, Chalmers tekniska hogskola, 6:30 PM  He had just walked out of the classroom in the V building. For the past forty five minutes he had been coding an exciting dynamic systems simulation after having completed a late and rather boring simulation exercises session class. He had to take the road in front of the Chalmers Bibliotek library as he wanted to meet a friend staying nearby. As he walked past the Information Sciences department building there was a gust of cold winter wind that struck his face and he raised the collars of this jacket, sinking in his chin into its warm, furry interiors. It was December and it would get dark really early. It was dark now and hardly anyone else around.   He hummed a tune as he ran up the flight of stairs, the library was at an elevated level from the V building. He found himself humming some r...
