- IRC is a great medium for getting instant help (at least on the freenode IRC network). I have collected some tips about Getting help on IRC to help you get help instead of getting barbecued.
- knoba's factoids
I run a bot called knoba (short for knowledge base) on the freenode IRC network. Two channels I visit frequently are #postfix and #squid. So I have fed the bot with lots of factoids that you can query using !foobar in the channel. These are the factoids understood in #squid and #postfix. Please don't play with the bot publicly. Send it a "/msg knoba help" and learn how it works.
