Two great books that I've been reading lately are:
Microsoft Silverlight 4 and SharePoint 2010 Integration by Packt Publishing
Expert Python Programming by Packt Publishing
I don't work for Packt nor am paid to promote any of these books. I just like the way the material is presented. I find the books easy to read, information is presented in a meaningful way, and the material/examples are top notch.
These are two resources any programmer should have on the old bookshelf, or in the e-reader.
