--------------------------------------------------------------------------- Haskell Weekly News http://sequence.complete.org/hwn/20100222 Issue 150 - February 22, 2010 --------------------------------------------------------------------------- Welcome to issue 150 of HWN, a newsletter covering developments in the [1]Haskell community. From the very pits of Harddrive failure I return... The Haskell Weekly News Reborn! Last week, on friday, my HWN machine suffered what can only be appropriately named a unbelievably poorly timed hard drive failure, hence the lack of an HWN. I trumphently return this week with a megaedition. Tons and tons of awesome stuff happened in the last two weeks. So I won't make you wait any longer, haskellers, your Haskell Weekly News!
