Unstructured Datatypes in Postgres – Hstore vs. JSON vs. JSONB
All about when to use unstructured data types in Postgres, such as Hstore, JSON, and JSONB. The tl;dr is that the right data type depends on your use case. Here we dig deep into the benefits, and why JSONB became so popular since it first got real and proper support in Postgres 9.4. The B in JSONB stands for better.

What Template Haskell gets wrong and Racket gets right
Why are macros in Haskell terrible, but macros in Racket great? There are certainly many small problems with GHC’s Template Haskell support, but I would say that there is one fundamental design point which Racket got right and Haskell got wrong: Template Haskell does not sufficiently distinguish between compile-time…
