4 blogs - 4 maybe not so different subject

I would like to present 4 interesting blogs from 4 different area:

1. Bash Cures Cancer, how it is easy to guests, is a nice blog mostly about Bash tips&trick. However, you can also find infos about other FOSS.
2. I'm not sure if you can call Molecules of the Month @ 3DChem a blog. I think it's older than idea of blog (it has been started in 1996). The subtitle (molecules of the month) indicates one molecule per month, but molecules have been added in random manner - no molecule between October 2007 and January 2008 and 4 in January. Anyway, the choose of molecules are quite good and the additional information can be really useful.
3. Bad Astronomy Blog is a good blog about astronomy. I visited it first because of this entry, especially because of this picture. Just be aware that from time to time there are some politics/religion related entries.
4. Finally, Online Video Streaming Archive is looking promising place where Nature (one of the best/the best scientific journal on Earth ;) presents streaming videos that feature interviews with scientists behind the most important present research.
