Haskell is a modern, purely functional, non-strict language and I recommend anybody interested in programming to take a look at it. GHC is the current compiler of choice and Hugs an interpreter that is especially useful for getting started.
Sydney has a lot of exciting activity around functional languages. SAPLING is a local interest group for programming languages that has been going for a few years, and another group named fp-syd that is focused on functional programming languages sprang up recently. All the meetings have been great so far, with lots of interesting talks and people to meet. Come along if you can!
xmonad is a tiling window manager written in Haskell that makes my life better. It uses some novel (and well-documented) data structures.
I read classics, science fiction, supernatural horror, fantastic fiction, and whatever else takes my fancy. Some authors worth recommending are G.K. Chesterton, Jorge Luis Borges, and Mervyn Peake. If you want to, go and look up their work, it's good stuff.
And some appropriate links:
