All Your Comparable Types — The introduction of generics was bound to create edge cases. One is described here around interface implementation vs. constraint satisfaction. “As we’ll see in a bit, in Go 1.20 constraint satisfaction is not quite constraint implementation anymore.”

Type Embedding: Go's Fake 'Inheritance' — Inspired by a “Keep Your Java Out of My Go” Reddit post, Zach shows how leaning too hard on object oriented ideas can cause hard-to-track-down bugs. But if you’re probably going to do it anyway.. read this to help debug later.

If you're curious, the not-particularly-edifying Reddit post that inspired the above was 'How to deal with Java developers polluting the Go code?'

IN BRIEF:

• ▶️ A developer explains how he picked up a $3,133.70 bounty for finding a XSS vulnerability in Go's x/net/html package. There's a code example of the problem and the resulting patch.

• Generics have been in Go for roughly a year now, so 🐦 what have you been using them for, asks Kelsey Hightower?

• Brandur Leach has some findings from six months of running govulncheck in CI.

go test and Parallelism — “Because I feel the concurrency behavior of go test is non-obvious .. I wanted to write something up here.”

🛠 Code & Tools

Opossum: A Basic Web Browser Written in Go — A fun project, though you might need to have (or set up) a Plan 9-derived OS to get it running (though someone claims success on macOS). As user liotier said on Hacker News, though: “any sufficiently brave or delusional soul that ventures into even the most rudimentary web browser development is a hero to me”.

Gin 1.9: A Fast HTTP Web Framework — We don’t often link to Gin because a) it doesn’t often get big updates, and b) it’s hugely popular and you probably use it already ;-) If you do, v1.9 is out, and if you don’t, it’s worth being on your radar.

VHS 0.3: The 'Home Video Recorder' for Your CLI — A tool plus scripting language for performing actions on the terminal which are then recorded into an animated GIF (or an MP4, webm file, or series of PNG frames). “Write terminal GIFs as code for integration testing and demoing your CLI tools.” v0.3 adds support for hosting said GIFs on Charm’s own vhs.charm․sh service.
