Intallation CUDA to Ubuntu 12.10 with Optimus Nvidia Cards

I installed Ubuntu 12.10 to my brand new machine but as always I started to deal lot of deriver problems coming around. Most consuming trouble was about the Nvidia drivers. I installed all kind of drivers suggested by the Additional Drivers tool and the Nvidia website but I cannot get my Graphic card working. After hours of investigation see that with the new generation notebooks with Nvidia cards there is a new technology called Optimus. With that system, new machines have two different graphic cards as the Intel’s native one on the mother board and Nvidia Card.

However, Nvidia is deficient to provide a driver supporting new tech on Linux machines. As always solution is taken by the open source approach, Bumblebee driver interface is developed. In Continue Reading


Simple hack to connect an authentication needed internet. (like in Starbucks)

For the notion of tradition I need to say that “all the information for educational purpose”.

We follow the process as, first look the LAN for other hosts’ IP addresses. Find a good looking IP (luckily connected to internet already.). Then retrieve the MAC address of that IP by using ARP protocol. Set your MAC address to retrieved one. Check whether you can surf. If you can’t, try another victim IP. Continue Reading

Creating Custom Linux Command

Sometimes you may need to repeat lots of linux command on terminal for any aim. It is some time so boring to type all the commands again and again so the solution to create  own commands to execute all the repetition in one.
