Errors on the project build path when using Eclipse
When I debug the framework source using Eclipse, there are some errors on the project build path.
Error messages I saw are the following :

Project 'Android' is missing required library: 'out/target/common/obj/JAVA_LIBRARIES/google-common_intermediates/javalib.jar'
Project 'Android' is missing required library: 'out/target/common/obj/JAVA_LIBRARIES/gsf-client_intermediates/javalib.jar'

Solution:
Goto Project>Properties and libraries section and edit first one to

"out/target/common/obj/JAVA_LIBRARIES/android-common_intermediates/javalib.jar"

and remove second one.

Missing required library when import the android source 4.0 to Eclipse
After this, the build path errors were gone, but I got about 200 errors referring to missing types. This could only be another classpath problem for Eclipse. Here are the extra libraries, that we have to add to the .classpath file:

<classpathentry kind="lib" path="out/target/common/obj/JAVA_LIBRARIES/android-support-v13_intermediates/javalib.jar"/>
<classpathentry kind="lib" path="out/target/common/obj/JAVA_LIBRARIES/filterfw_intermediates/classes-jarjar.jar"/>

or add these two files as externals jars in the above mentioned area, i.e., libraries section in Project>Properties

Hope this solves your problem...

This problem can be occurred at two instances.
1. Fresh installation:

1. Download the driver from nVidia website
2. Copy the file to the disk. (It looks like "NVIDIA-Linux-x86_64-319.17.run", depends on your version)
3. Now just type the following command from terminal:
sudo sh ./NVIDIA-Linux-x86_64-319.17.run
4. Follow the on-screen instructions and finally reboot.

2. Problem after upgrade:

1. Login into command prompt
2. Run the following command:
sudo sh ./NVIDIA-Linux-x86_64-319.17.run
3. It will ask to delete previous installation. Accept all the prompts and also the one to edit xconf file.
4. Finally it will reboot and system boots normally.

After successful boot, you can configure your driver in the System>Preferences section.

Other work-arounds:
1. When prompted the low graphics mode, select the "Restart X" option. This will work in some cases. But every time you boot, perform the same.
2. Also try blacklisting "nouveau" (if you find 'nouveau' by running the command 'lsmod'). To do this, type the following command:

sudo gedit /etc/modprobe.d/blacklist.conf

This will open a document. Add this line at the bottom:

blacklist nouveau

3. Reboot to get some relief.

To set the JVM heap size, compile the program normally.
For example, consider Runtime.java program.

Compilation: javac Runtime.java

Now, to set minimum heap size(let, 16 MB) required by JVM, run the program as follows :

java -Xms16m Runtime

We can also restrict maximum size(let 512 MB) utilized by JVM:

java -Xmx512m Runtime

Both these options can also be combined to specify upper and lower bounds of JVM heap size:

java -Xms16m -Xmx512m Runtime

Now you can run a program that requires huge computational space.

Looking for a app can do your work better with little/no effort, then here it is.

Connecting to internet using mobile partner or some other program is simple. But it consumes your system resources(around 200 MB of RAM). You can simply save your resources by using command prompt. This method is applicable only on Windows platform.

First, install the device driver and create the dial-up connection, or just install the mobile partner(or software that came along with your modem) and connect using it(it will automatically create the dial-up connection). now you can exit that program.

Here is the procedure to connect using command prompt:

Open command prompt
Type the following command

rasdial "CONNECTION NAME"

Ex: rasdial "TATA DOCOMO INTERNET"

To disconnect,

rasdial "CONNECTION NAME" /Disconnect

You can also automate this process by creating batch file.
Connect
Open any text editor and copy the following code

:Redial
rasdial "CONNECTION NAME"
if %errorlevel% == 0 exit
goto Redial;

Replace the CONNECTION NAME with your connection name(you can rename it) and save it as connect.bat

Disconnect
Open any text editor and type the following

rasdial "CONNECTION NAME" /Disconnect
exit

Replace the CONNECTION NAME with your connection name(you can rename it) and save it as disconnect.bat

Save them at the location of your convenience and just double click them to connect and disconnect a dial-up connection.

Recently I faced an issue with my laptop keyboard. Some of the keys are not working.
As it is still under warranty, I thought of replacing the keyboard.
When I contacted customer support, after listening to the problem he asked whether I tried DRAINING.
Then he explained me the procedure, and guess what - it's working perfectly again.

Here is the procedure of DRAINING:
