Techno-Activism Third Mondays (TA3M) is an informal meetup designed to connect software creators and activists who are interested in censorship, surveillance, and open technology. Currently, TA3M are held in various cities throughout the world, and is hosted in San Francisco by EFF.

This month's topics: Deterministic builds (and previously undetermined SSL bugs)

This week, we'll be joined by Seth Schoen, who'll demonstrate some of the challenges of protecting even open source from malicious insertions, and how we might be able to make stronger guarantees about the provenance of your computer's code.

After that, a Q&A and discussion with some of the folks who've been co-ordinating the response against Heartbleed, including what went wrong (a lot), and what should we fix first?

Join us for snacks, networking, and tech talk this Monday

Time: 6:00pm

Location: EFF offices, 815 Eddy Street, San Francisco (we'll wait at the front door until 6:15; after that, ring ext. 118)
