There are a lot of topics being discussed in Herding Code episode 178, Async, C# Syntax, AngularJS, Document Databases, Podcast Hosting, A New Job and Summer Vacations.
I really enjoy the Herding Code podcasts. The guys have a lot of expertis and are good at sharing it with the listeners. Today they shared a lot about async and the C# syntax.
K Scott Allen goes into his experiences with Angular and although I already have it on my "must try" list this talk pushed up towards the top.
They also go into document databases, mainly MongoDB, and give some good advice on how to improve performance.
