I am a researcher working in the biological physics field. I started to use Linux back in 2001. After that, I fall in love with Linux. I use it in my research and also daily work, such as document processing, web surfing etc. In this blog I record my Linux experience. I'd like to focus on the research experience using Linux, especially I want to explain or give some simple tutorials on software commonly used in research, such as OpenOffice, Octave, R, xfig, gimp, C++ , etc. This blog was first set up mainly for my personal use, but it turn out to be more useful than I had thought.
Please note that I have no intention to claim that the materials here are my original. Actually most of them just my collection from all over the world when I searched the internet to find solutions. If there is any, if you think infringement of your copyright, please contact me and I will immediately take actions on that.
