Even I have been using it for long time; I always had confusion each time when I use it. 590 more words

Nice Article on the class diagrams

Internship pt. 2: My project

Here’s some stuff about the work I’m doing here.
I’m working on an open-source project called Coccinelle, which is a tool for refactoring c code and fixing bugs.

Linux Nears Total Domination of the Top500 Supercomputers

It’s always been fun watching Linux claim a bit more of the Top500 with each successive ranking of the world’s most powerful supercomputers, but with this week’s release of the Top500 list’s 43rd edition, it’s beginning to look like the free and open source operating system is getting pretty close to complete domination. 6 more words


Linux và hệ điều hành

Nhiều người cho rằng Linux không phải là một hệ điều hành hoàn chỉnh mà chỉ là một phần nhân (kernel) của hệ điều hành. Điều này đúng đối với người dùng cá nhân còn không đúng đối với những người làm kỹ thuật và nhất là các Linux engineer. 261 more words
