Advanced Network Architectures With ZeroMQ
This was a talk on ZeroMQ by Zed Shaw. He and his talk were a lot more sedate than I expected. He's also older than I thought he was.
He uses Emacs, screen, and Ubuntu.
ZeroMQ servers should not be exposed to the naked internet. If you send it invalid protocol data, assertions will kill the process.
The talk was very fast, but most of it was like the ZeroMQ guide.
