release
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.
