Ok, so I've just posted my current non-technical reading list so now here's my techinical currently-reading list:
Programming Ruby: The Pragmatic Programmers' Guide, Second Edition - Dave Thomas, Chad Fowler and Andy Hunt
I've been playing around with Ruby for quite some time now but I need a good reference book for it. What other book to read than main source of Ruby knowledge out there! After the announcement of the DLR (which I've downloaded already), I can't wait to do more of Ruby natively on .NET!
Programming WCF Services - Juval Lowy
Another great master work by Juval. If you're currently doing WCF (or thinking about it) then you should definitely pick this book up! That's all I have to say about that...
