The people at JetBrains have given the GlusterFS project an “unlimited # of users” license for their cross-platform PyCharm Python IDE:

Everyone has their own preferences with programming IDE’s, and I’ve used several over the years, generally based on Eclipse. However, I happen to like PyCharm at the moment, so applied for JetBrain’s “free license for OSS projects” for the GlusterFS project:

If you’re a GlusterFS developer (with at least 1 commit on record) email me (jclift@redhat.com or justin@postgresql.org) and I’ll send the license file to you.
If you want a PyCharm license but aren’t a GlusterFS developer yet, getting started with GlusterFS development is both interesting and fairly easy:
