The HTTP Routing Enhancements in Go 1.22 — The Go team’s official take on the new HTTP routing enhancements in Go 1.22: “Go 1.22 brings two enhancements to the net/http package’s router: method matching and wildcards. These features let you express common routes as patterns instead of Go code.” These features are not universally adored so far, however.

Go Enters the Top 10 in the TIOBE Index (Again..) — This story has been doing the rounds on social media, though the same author wrote a similar story a year ago. We also covered Go making it into TIOBE's top 10 six years ago (in issue 168) so don’t read too much into this (especially given how the stats are obtained). Nonetheless, #8 is the highest position Go has reached, so that’s neat.

Kubernetes CPU Limits and Go — Go’s runtime doesn’t inherently know that it’s running within a Kubernetes environment, so you may want to take CPU limits and GOMAXPROCS into account if you’re doing this.

Give Go's goto a retry? — It's surely only a mild exaggeration to say many of us were brought up to 'never use goto' but a lot of developers have a strong aversion to its use. Nonetheless, Go has it, it’s used in the standard libraries, and it can be useful in a variety of cases.
