The Open Source Paleontologist is my next spotlight Geo-Paleo blog. From the site:
"Ramblings on the role of open source software in paleontology, the latest and sometimes not-so-greatest ways in which we reconstruct the past, and the occasional bits of career advice and paleo news."
This is from a paleontologist somewhere in the US who focuses on the free stuff out there we all could use. A definite useful site since if there is one thing I know I can use, it's free stuff.
