Introduction

I am Umar Muhammad Sheikh. Though jobbing is not the most significant part of my life yet, I can describe it in complete detail right now. This is my first day at AboutUs, and so far, the first hour has not yet expired. Period! My first task is to write my own second home page. The first one I made was in the first introductory computer science course, and I made it for getting a good grade. This is not much different!

Martial arts (2nd dan Black belt in Tae Kwon Do), graph theory (cleared PHD qualifiers), Scrabble, a bit of reading, and a lot of day dreaming

Religion

Islam

Linux commands

more ~/.bash_history,

tail -f filename,

Vim commands

1 'CTRL+z' to send a task in the background, and 'fg' to bring it back. if there are more than one programs running, type 'jobs' to view them, and if you want a program called 'xyz' to run, there is a number next to the program 'xyz', example, n. type 'fg n' to run it. 2 'gg=G' to properly indent code (but this is by reaming in the command mode and not entering the : in the beginning) 3 '%s/ab/cd/g' to replace all occurences(the work of g) of ab with cd in a file u opened in vim. this option is given in the command mode 4 'CTRL+w+v' so that the same file opens again vertically next to itself

-What happens when you run the following program:
-copy the line below twice, the first time without quotes.
-"copy the line below twice, the first time without quotes."
-==Answer?==
-ehehehehehe, so what is the answer!
-When you do as instructed, you get a repeat of the two lines as they are now. The first line without quotes becomes a new instruction. Your interpreter then executes it again and so you get a never-ending program! This is obviously in pseudo-code though.
