What's in an (Alias) Name? — Generic alias types are coming to Go 1.24 (expected in February 2025) in line with this proposal, building on both type aliases and generics. A major use case for type aliases is the ability to refactor without breaking compatibility. Robert explains the basics of type aliases and why bringing them to generics required extra work.

Go's Singleflight Melts in Your Code, Not in Your DB — The last post in a series on concurrency describes singleflight, a non-core package (that’s maintained by the Go team) that ensures a function is only run once and its result reused by later callers.

Register Allocation in the Go Compiler — Vladimir maintains GCC’s register allocator system and struggled to find docs on how Go does it, so he went diving into Go’s source code. This is deep stuff, but long story short, he likes Go’s approach: “the current Go RA is a well-designed and creative RA.”
