As I need to post my working progress for the Google Summer of Code project, this github blog is a good place to share this information. My project is a Biopython project. Before start the real coding, it's better to play with some existing python code. So yesterday, I changed the blog generating system from Octopress to Pelican. Octopress is based on Ruby and is widely used by github bloggers. But, as I know little about Ruby, it is complicated and hard to use for me. Pelican is pure Python. It really get much more easier. Actually I think Pelican is more easy to install and use than Octopress even for those who know little about both languages. The comment system--DISQUS has not been setup yet, as I forget my DISQUS account. Will fix it later.
