Ubuntu Running in low graphic mode

the cause of this problem is the graphic driver is override by some other software update.

you should download some driver that suit your graphic card and then reinstall.

1. press Ctrl+Alt+F2 (Ctrl+Alt+F8 and BackSpace I can't remember meaning)
then close x server by command "/etc/init.d/gdm stop"
2. sudo ./your driver.run
3. "etc/init.d/gdm start or restart"

Finish then "sudo shutdown now" if you can't back to normal graphic mode = ="

change permission linux

example
chmod 777 [folder or files]

Solve Password for Start-dfs.sh

if you set hadoop command in permission folder then you can't run this command.

my method is "move all of hadoop to home folder".

this may solve.

or if you should insert password 2 times don't tired to type.

the first for datanode and the second for secondary namenode.

My Stupid about Grave accent

I have one problem can't solved for a long time.
That is I can't type ~ in windows 7.

To solve this only hold that key (shift + ~)
if not hold it then it will change your language.

Installing NVIDIA NEXUS for Debug CUDA , OpenCL

When installing, Nexus Beta 1 says that the required version of Visual Studio is not detected. But Visual Studio 2008 SP1 is installed! What is wrong?

Nexus Beta 1 looks at keys in the Windows registry in order to determine if Visual Studio 2008 SP1 is installed.

The registry keys read by the Nexus Beta 1 installer are:

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0 where key ApplicationID has the value: REG_SZ “VisualStudio”

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DevDiv\VS\Servicing\9.0 where key SP has the value: REG_DWORD 0x00000001

If your registry does not have those values in those keys, then unfortunately, Nexus Beta 1 will not install.

How Different In Learning English By Game and Book and Movie

I just play some English (with human sound) Game.

and after I read a English book too.

something come into my mind.

Yeah , That is how I feel "Desire to want to use English".

The game give me a feeling expression but reading the book is not.

Same as the movie give but poorly english skill like me can't follow all word in movie.

Little different about game is I can control some part I want to follow like in a strategy talking.

But in the movie you should follow as fast as they talk.

Finally , I think the best learn is learn everything mix together then you will got every skill needed. :)
