### AI overview

An Erlang developer describes deploying live upgrades for running OTP applications behind an in-browser IRC client. The article discusses release packaging, release_handler, .appup files, rebar, and an upgrade from R13B to R14 after encountering upgrade-related problems.

### Source excerpt

I've been building something in Erlang recently, provisionally called IRCCloud.com (mention this post if you request an invite!) - it's an in-browser IRC client that stays connected for you all the time, so you never miss the conversation. You can reopen your browser later and still have all the backlog. IRC is damn useful, and James and I are building IRCCloud to give you the advantages of IRC bouncer-esque functionality, with the ease of just opening a webpage.
