Google Chrome (actually Chromium) on Centos

Joy at last! Chris Staite from the University of Birmingham has built a statically-linked version of Chromium, the open source version of Google’s Chrome browser, for Centos.

NoSuchMethodError when running JUnit tests in Eclipse

This is worth a quick post as I couldn’t find a solution on Google and it took me an hour or two of fiddling.

Echoes of the past
