Hybrid sweet spot: Native navigation, web content
When we launched the iPhone version of Basecamp in February of last year, it was after many rounds of experimentation on the architectural direction. The default route suggested by most when we got started back in early/mid-2012 was simple enough: Everything Be Native! This was a sensible recomm…

Architecture of a Real World Haskell Application
There were numerous posts on reddit, SO and the like which were asking for how to architect real world Haskell applications. Well, this is my go at it for an in-house testing tool which is used extensively. I would not claim myself an advanced Haskeller, some of the code is probably not idiomatic Haskell (and also…

Minimum Viable Block Chain
Block chain is agnostic of any 'currency' and it can (and will) be adapted to power many other use cases. This is a ground up explanation of why the particular pieces (digital signatures, proof-of-work, transaction blocks) are needed, and how they all come together to form the minimum viable block chain with all of…
