A tough day at the office today..Couldn't spend much time on reading though..Would like to

rollup this week's entry with this tiny piece of trick..I have read elsewhere in the web to reset

the bios of the PC. It can be done with a tiny utility called "DEBUG" in windows. Just power up debug

MSDOS and enter the following commands

O 70 2E

O 71 FF

Q

Viola! the CMOS RAM gets invalidated by the process..Careful! Try at your own risk. Don't get back to

me for any problems :)

Some of my favorite quotable quotes

"Our greatest glory lies not in never falling, but in rising everytime we fall"

"College is the place where pebbles are polished and diamonds are dimmed"

"Strength is not measured by Physical fitness. It is measured by the presence of indomitable will"

"There is no right time to do a right thing"

"To know that we know what we know, and that we do not know what we do not know, that is true knowledge"

A very old shortcut in mathematics to find the squares of numbers having a '5' in the unit place. Nice one though..

45 * 45 = 2025

5*5 = 25 (unit place of both the numbers multiplied)

4 * (4+1) = 20

Combined together to give 2025. ain't this cool?

On Similar lines, 85 * 85 = 7225 ( 8 * (8+1) concatenated to (5 *5) )

65 * 65 = 4225..

Beware! it works only for squares of numbers with unit digit as 5. Now, the tough part

105 * 105..give a try...else find the answer in some other post of mine later..

Back to my school days, what was the name of the first dog in space was a standard quiz question..The answer was obviously Laika. More information about what exactly happened is available in this link.. Little hard to digest though!.
