Recently "Lama Bleu" has been working on a custom firmware image for the PlutoSDR.

gopass is a rewrite of the pass password manager http://www.passwordstore.org in Go with the aim of making it cross-platform and adding additional features. Our target audience are professional developers and sysadmins (and especially teams of those) who are well versed with a command line interface. One explicit goal for this project is to make it more approachable to non-technical users. We go by the UNIX philosophy and try to do one thing and do it well, providing a stellar user experience and a sane, simple interface.
