This is something I caught today in one of the mail chains of “security-basics” mailing list. God ! I love the way this guys explains TCP/UDP.

 Murda Mcloud to security-basics

I propose changing the name of this thread to ‘Starting up as an online
stand up comedian,(or a security consultant).’ Or both, perhaps. We have
seen some great material…and then we have this…

Two protocols, UDP and TCP are bar hopping across the US. TCP is making all
the decisions and doing all the planning.
“Do you want to go to Nebraska next, or Wyoming? How about New York?,” TCP
asks UDP.
UDP just shrugs like a bored teenager at every suggestion until TCP gets mad
and shouts, “God, you just don’t care what state you’re in, do you?”

This is something I collected over the internet and liked a lot. This definitely deserves a spot on my blog.

How to Start an Online Business for $100

By Christopher Null and Pc World , PC World , 11/05/2008
 
Today’s economy isn’t doing anyone any favors, and if you’re one of the unfortunate folks to have been served a layoff notice, you might be facing a long haul when it comes to searching for another job. Is now the right moment to put your long-lingering business idea into practice? While times may be tight for many larger enterprises, in many cases smaller, more-nimble companies are better able to withstand market uncertainty and weather downturns.
The best way to stick it to The Man? Start working for yourself by founding your own company. Working for yourself has some serious and obvious advantages over job hunting. Not only do you determine your own hours and decide where you set up your office, but you keep all the profits too.

This last week has been a mess. Caught in
some huge legal issues, may be sometimes I will write about it, for
the time being I am confirmed there are irrational illogical and
stupid people still out there. Getting India’s freedom last time
was easy, but now its impossible, because now the situation is
helpless. There is nothing you can do about these people but leave
them in their misery and continue with your life somewhere
else.
