Well... I'll *do* Java, but I'll be thinking of C++.
I'm still learning about the tools I use.
projects and hacks
I've been project lead on Openfire, an XMPP server used everywhere you can think of, and also work on Spiffing (military-grade information security), Metre (XMPP weird thing), and other random things.
I'm available for collaborations and discussions about collaboration or discussion. No, seriously, that's totally my bag, especially if words like "secure" are attached. But don't bother offering me paid work.
