If you have more than one system and need to acces all with a single mouse ?
Wanna hack your neigbour node and drive him mad?
you can use this code to move the cursor
and with little modification you can emulate a whole mouse and keyboard functionalities too …
To Do :
step i) run the server.class first in machine u want to control say A
java server <port_numbr 1000-65535>
step ii) run the client.class in second machine u have the mouse say B
java client <ip of machine say 10.2.3.1 > <port_number_server 1000-65535>
step iii) move mouse in machine B so that it moves on machine A
Algorithm behind :
i) get the mouse position from master machine
ii) send the position in a ‘encrypt‘ string with X and Y positions merged
as encrypt=X*10000+Y ( I use 10000 here assuming your screen resolution is not more than 10000X10000 
)
iii) send the string to slave node using Socket output stream
iv) get the encrypt string and extract x and Y position by
X=encrypt/10000;
y=encrypt – X;
v) Now move the position of slave machine by mousemove(X,Y) method
vi) You can add leftclick , right click and keyboard keys too as above

You can transform Your NUM lock and SCROLL lock led’s to monitor packets send and receive
Follow the simple steps below :
i) Installation:
Install tleds package bye sudo apt-get install tleds
ii) Configure :
now configure the interface you use
say for ethernet run tleds eth0
and for wirless run tleds wlan0
Perform a restart
iii) Customize :
Now you can adjust the delay to very quick response to low response rate by adjusting -d paramter in tleds
for very quick run tleds eth0 -d 1
for low speed run tleds eth0 -d 200
now you have tranformed your keyboard to packet monitoring system as below :
enjoy
Facebook mouseclicks hack !
Posted by: karthikselvakumar on: January 1, 2010
I came across a facebook application which counts maximum number of clicks per second and thought of emulating it in java 
it is as simple as a crap code … with simple steps Download it from here
step 1:
I wrote a java code which automtes mouseclicks for N times by for loop
the code seems like :
import java.awt.Robot;
import java.awt.event.InputEvent;
/**
*
* @author karthik
*/
public class Main {
/**
* @param args the command line arguments
*/
public static void main(String[] args) throws Throwable {
Robot r=new Robot();
System.out.println(“Hurry up ! you have 10 seconds left “);
System.out.println(“This time you must have focused your mouse pointer on START button of facebook appln”);
r.delay(10000);
// TODO code application logic here
for(int i=0;i<10000;i++){
r.mousePress(InputEvent.BUTTON1_MASK);
System.out.println(“Clicking “+i+”th time “);
r.mouseRelease(InputEvent.BUTTON1_MASK);
System.out.println();
System.out.println();
}System.out.println(“Congrats ! you did it man B-)”);
}
}
now save the code as Main.java in a directory c:\ in windows or /home in linux
step 2:
open terminal
compile the java code by running from the location where code is located by
javac Main.java
in the mean time open the facebook application
step 3:
Run the java code now this is critical part
java Main
( you can directly run this by extracting Main.java.zip from above )
you will get a screen saying
“Hurry up ! you have 10 seconds left
This time you must have focused your mouse pointer on START button of facebook appln”
now focus your mouse pointer to the START button of fb appln
you will get a count more than 200 sometimes even 300 clicks per second ( depending on ur jvm )
for more clear details watch the video below :
Thank you
Disclaimer :
If you move your mouse button other than start button you will get random results around screen and may hang at times so keep the mouse pointer in START button for atleast a minute

Well this is a tricky part where I have struggled for a function returning cpu temp in java and failed . Then I chose lm-sensor for this purpose .
step1
Installation :
install the package lm sensors for your linux distro
sudo apt-get install lm-sensors
step 2:
run sensors in terminal
if you have installed for first time probe it to kernel first
step 3: restart the system and try sensors now
I have a core2quad processor and i get temperature of four processors as
karthik@Karthik:~/Programs$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +47.0°C (high = +74.0°C, crit = +100.0°C)
coretemp-isa-0001
Adapter: ISA adapter
Core 1: +37.0°C (high = +74.0°C, crit = +100.0°C)
coretemp-isa-0002
Adapter: ISA adapter
Core 2: +39.0°C (high = +74.0°C, crit = +100.0°C)
coretemp-isa-0003
Adapter: ISA adapter
Core 3: +46.0°C (high = +74.0°C, crit = +100.0°C)
step 3:
call the process class of java and get back the string returned
import java.io.*;
class cpu {
public static void main(String []args) throws Exception
{
Runtime r=Runtime.getRuntime();
String f,temp,res=”";
int i=0,j=0;
f=”sensors”;
Process p=r.exec(f);
BufferedReader pin=new BufferedReader(new InputStreamReader(p.getInputStream()));
while((temp=pin.readLine())!=null)
{
System.out.println(temp);
}
}
}
Then make it flexible for your own purpose by proper string parsing ….
Thank you !
Avatar (2009)

I have to start with saying Cameroon dissaponted me …
Even storyline doesnt seems to be great but visual effects are fantastic and real . Na’vi’s are the creatures in a planet pandora . For me their appearance resembles as traditional character Lord Rama . Avatar too is sanskrit word meaning phases of vishnu where one is Rama . I guess it may be a copy 
.
No great explanation about the planets existence whats their origin where is it actually located .. blah blah . The most humorous thing I noticed is the base attack with lumps of fire ( where the place people struggle for oxygen , but how combustion is possible :P ) .
I don’t know where to categorize this film .. either in animation or comic series or scientific fiction or just an entertainer .. Only plus point makes the film still run is 3D . the existence of evya the holy god still confuses me whether film falls under spiritual r religious category .
The soul DNA transformation concept , electrochemical network of trees , the precious stones significance and the hair like generic interface between avatar and rest living creatures could be explained little more.
Its seems like Cameroon loosing his originality and resembles Speilsburg ’s Jurassic park. A must watch film for kids < 10 .
Well if you fix on to watch this movie I recommend you to watch it in 3D with surround sound ( don’t watch it out in your damn old pc and get disappointed )

Ubuntu 10.04 Lucid Lynx

Ubuntu 10.04 release named Lucid Lynx is the next release..
Well 10 second boot time is the main aim of this release it seems . I felt the high speed booting of my 9.10 karmic now from older hardy heron( 65 seconds to 25 seconds ) . still lucid aims at 10 seconds boo time as the main aim to achieve . This release seems to be released at next year 2010 .
The 10 second boot time is acheived by equal partitoin of modules at start up with:
i) loading the kernel and initramfs should take two seconds,
ii) driver loading, filesystem mounting, and other “plumbing” should take two seconds,
iii) launching Xorg should take two seconds
iv) the remaining four seconds should be used to launch the desktop environment and other services that are part of the user’s session.
( if you are not well verse in this terms then please open your eyes after 10 seconds from start of booting )
The computer should be fully booted and ready to use at the end of ten seconds
but as a sad part GIMP is removed from standard installation of ubuntu when queried developers say :
- the general user doesn’t use it
- its user-interface is too complex
- it’s an application for professionals
- desktop users just want to edit photos and they can do that in F-Spot
- it’s a photoshop replacement and photoshop isn’t included by default in Windows…
- it takes up room on the disc
Im realy sad about this plot and really the fifth point “it’s a photoshop replacement and photoshop isn’t included by default in Windows…” . comparing a linux distro with a windows .
If they speak so then linux must be a simple skeleton with a sucky media player and a paint program as some others do.
well even it ’s sad , I guess it doesnt takes more than a couple of minutes to trigger sudo apt-get install gimp
Make your own OS

Make your Operating System of your choice with five simple steps ( for linux geeks only ) :
Step 1: Download and install Reconstructor
and run sudo dpkg -i reconstructor_2.8.1_by_hacktolive.org.deb
Step 2: Meta–>System Tools –> Recontructor
Now open the package reconstructor from system tools and enter your root password . Click Next .
Step 3: Choose alternate cd option
on available options choose alternate cd to make a installable bootable OS , or live cd fr live session of the cd
Step 4: setting up the base
Now choose the working directory and swap space to work up . Locate the iso image of your ubuntu CD or enter Ubuntu CD into cd rom
Step 5:adding up your own packages
Now you can add new packages or delete the unwamnted ones and choose wallpapers , thems , the appln to boot on start up , the one you dont need with simple interface
and finally create disk will create your fresh piece of distro
You can have a try of remaster sys or if you are really a linux geek try to do from scratch try the lengthy step as in Linux wiki with squashfs tools
Now you can burn this iso image and distribute among your circle and call this as your NEW DEVELOPED OS as people say
Is New Orkut Really New ?
Posted by: karthikselvakumar on: November 16, 2009
Well few days Back I heard something called new orkut . It took weeks before since last time I logged in Orkut . Facebook attracted me more and some how addicted to it .Now heard about “New Orkut “ I came back to my old orkut .
Goodness I got invite from some one ( sad thing is New Orkut too is a Invite and use system ). Well when I saw try new orkut at top , Clicked it really expecting a amazing wonder as an Alice . But I seen a page something very similar to face-book which disappointed me a lot .
What they say new in this version are …
i) They say ‘ Friends updates are available to every one ‘ .. Do you guess this thing new as an FB user
ii) second ‘Every one can comment on any friends notification , updates ,application and friend acceptance ‘ .
iii) A new thing I found interesting is Video chatting integrated with orkut ( pity on Linux users , it says ‘ OS not supported ‘)
iv) Best feature I found in this release is IE 6 is not at all supported .
v) Next humorous thing I found is adding a general sucky template and five sticky colors of their own choice and they said ” Pick your favorite colors We’ve made orkut even more colorful “ ..
vi) Speed is the main thing they mentioned they have increased .. But instead of static pages I can see my page still buffering in status bar ( stealing my pity small free download limit I have 
)
vii) And the highlight of all is they mentioned moving chat bar from left side to right side as a new feature ( I guess the only thing they didnt imitate is the notification bar you can see under as In face Book )
I guess it may take time to digest this things and to switch over to new orkut . The thing I like the most is the prefix Beta in Orkut ( a word which can answer almost all the bugs user raises )
