release
Go 1.24 Released
Go 1.24 has some nice performance and testing improvements, and adds weak pointers and better finalizers
Go 1.23 - 1 - 2 - 3 Surprise!
A unique look at iterators, a controversy and some hidden surprises
Go 1.22 Released
Everyone’s going loopy about Go’s latest language changes. Nobody seems to have noticed an important fix
Go 1.21
Go 1.21 has just arrived! It has some nice things like PGO, and slices.Sort(), but beware of a pitfall
pitfall
Go’s “Reference” Types
It’s important to understand the behaviour of maps, slices, etc

pragma
Build Tags
The other “directive” that I didn’t cover last week is //go:build. This time I look at how and why you would use build tags and the new syntax.
Compiler Directives
A look at all of Go’s pragmas (except build tags). How //go:debug directive enhances Go’s backward compatibility. Plus recent changes to the language that af...

profile
Profile Guided optimisation
Learn how PGO improves use of inlining and CPU instruction caches. I show how to get biggest boost for your projects by using the right CPU profile
CPU Profiling and Flame Graphs
Easily track down performance problems with flame graphs.
