Tim Bray's Go Diaries: Generics — Tim (one of the original co-authors of the XML spec) finds a use case for generics in his Quamima pattern matching library, only to find that there are some ‘bumps in the road’ which he shares here for everyone’s benefit.

Tim concludes: “I don’t hate Go’s generics, which is actually pretty strong testimony given that I spent the best part of a couple of days fighting all the stuff described above. But, my guess is the Go generics story is isn’t finished yet.”

Calculating Type Sets Is Harder Than You Think — If you like going into the weeds of typing, this is going to be catnip to you as the author picks up on something in the generics spec and walks us through the math (and code) to show just how hard proving a type set is empty really is.

Let's Build a Distributed Postgres Proof of Concept — Could you put together a mini Postgres in 600 lines of Go? Another example of some of the complicated things you can get done with just a little bit of code in Go (even where third-party packages do much of the lifting.)

Roaring 1.1: Roaring Bitmap Data Structures in Go — Bitsets/bitmaps are useful data structures but can take up a lot of space if uncompressed. Roaring bitmaps are particularly efficient compressed bitmaps and used in systems like Lucene, ClickHouse, and Spark. If this area interests you, you may also want to check out Dgraph's Sroar which promises even more efficiency as well as their fantastic writeup on the work (illustrated above).
