For quite a bit I’ve been playing with the idea of “schemaless” models, intrigued by the idea of dumping entire hashes into database fields instead of having to add every little setting as a real database column.

Wow, that’s… Continue reading Cells-Hamlit: The Fastest View Engine Around.

Representable 2.4 internally is completely restructured, it has lost tons of code in favor for a simpler, faster, functional approach, we got rid of internal state, and it now… Continue reading Representable 2.4: How Functional Programming Speeds Up Rendering And Parsing.
