Mirah is a JVM language that's modeled after ruby. Alas, it isn't complete, but it is awesome.
Well, on Tuesday (5th April 2011) I gave a presentation at IPRUG, the Ipswich Ruby User Group. It wasn't great, in fact it was my first presentation since doing my dissertation in 2008. That said, the slides were pretty good...
Anyway, thought I'd post my slides here in case anyone's interested. Click here to see them, and imagine a hopeless geek rattling through them way too fast.
