Can I use it to monitor source code changes of a Google Code projects, eg (https://code.google.com/p/dcef3/source/list), or a github project? If not can anybody recommend a good tool for this kind of task? Thanks.

which refers to an Atom feed for the project's commits.Same for Github projects, e.g. at https://github.com/petdance/ack2 you will find:
<link href="https://github.com/petdance/ack2/commits/dev.atom" rel="alternate" title="Recent Commits to ack2:dev" type="application/atom+xml" />There's similar functionality on github (but I haven't found documentation for it)... Example: https://github.com/shirou/kptool/commits/master.atom
