is an open source engineering portal, your one-stop shop for news, links (below), other resources, and profiles of open source engineering software. It also hosts package repositories for running some software on Ubuntu 16.04 "Xenial Xerus" and Debian 9.0 "Stretch".

This site does not (yet) have discussion forums or email lists on this topic. Those are available from the competition, or at the lists/forums of individual projects.

However, this site does welcome contributions, corrections, completions, etc. Send such correspondence to Adam Powell.
