Dedicated to all my friends in research :D :D :D

One politician, One thief & One Scientist died and went straight to hell.

Politician said "I miss my country. I want to call my country and see how everybody is doing there." She called and talked for about 5 minutes, then she asked "Well, devil how much do I need to pay for the call????

The devil says "Five million dollars". The Politician wrote him a cheque and went to sit back on her chair.

Thief was so jealous, he starts screaming, "My turn! I wanna call the my group members, I want to see how everybody is doing there too". He called and talked for about 2 minutes, then he asked "Well, devil, how much do I need to pay for the call????

The devil says "Ten million dollars". With a smug look on his face, he made a cheque and went to sit back on his chair.

The scientist was even more jealous & starts screaming, "I want to call my institute and talk to my fellow Scientists, Project Leaders, Research fellows, Project fellows/assistants. He called all those people and talked for twenty hours about promotions, publications, impact factor, CRs, inter-departmental and intra-departmental politics. He talked & talked & talked,
then he asked "Well, devil how much do I need to pay for the call????

The devil says "Ten dollars". The Scientist is stunned & says "Ten dollars??? Only ??"

Devil says "Hell to Hell is a Local Call " :D :D :D

using SCREEN command in Linux

There are times when you want to log off your system, but you want the programs to be executed on the server machine which you've initiated from your system. You can use screen command which serves this purpose. It starts a session within the session that you have logged in. Even if you logout from your system, the screen will keep on running until the server stops or you forcefully exit.

Here are the commands which you should use.

$screen //starts a new session in the logged session

$./a.out > output //some command which you want to get it executed

$ CTRL + a + d //closes the screen and brings you back to the original session

$screen -r //displays the screens running on your machine

Hope this is helpful :-)

Installing gnuplot on windows

You can install gnuplot on windows easily to plot the graphs.

Download gnuplot from this

There is no need to run any exe file but directly copy them to some directory on your system and then make a shortcut to wgnuplot.

It is also useful to install ghostview which allows you to view postscript graphs made with gnuplot. You need gs860w32.exe and gs49w32.exe (or higher?).

Instructions for installing ghostview can be found here;

Identify the ports in linux

For socket programming, you need to use the port. If you want to identify the ports which are active, you can use the following commands. Generally in linux, the ports from 0 to 1023 are reserved and can be accessed only as a root user.

For checking the information about the port, you can use netstat

If you want to know more about this command, you can check its man page
$ man netstat

But for quick reference, you can use any of these for the appropriate purpose.

For finding the open ports:
$ netstat --listen

For finding the open ports and established TCP connections:
$ netstat -vatn

For checking information about a port,
$ netstat -anp | grep <port>

For identifying the ports already in use:
$ netstat -atnp | grep LISTEN
