Conc: Better Structured Concurrency for Go — Go’s concurrency story is a good one, but Conc aims to make it even safer and easier by providing abstractions for various concepts (think pools, concurrent mapping and iteration, and panic catching) and techniques so that goroutine leaks and unhandled panics can become a thing of the past.

Sourcegraph

Go 1.20 Cryptography — The second release candidate of 1.20 is out, and some key crypto changes land, with new implementations of some old (and vulnerable) packages, including a new ECDH package, a replacement for math/big (with a performance hit) with more to come (hopefully…)

IN BRIEF:

Go 1.20 Release Candidate 2 has been released.
📅 The CFP for GopherCon Europe 2023 is now open if you want to speak – it closes on February 26. The event itself is both virtual and in Berlin on June 26-29.
The latest version of Go's VS Code extension now includes static analysis for finding and reporting known vulnerabilities in your dependencies (powered by Go's vulnerability database).

The Go Libraries That Never Failed Us: 22 Libraries You Need to Know — While there are other lists out there (the huge Awesome Go, for example), this one is tightly curated and only includes libraries they’ve used in production. Also, they’ve included some anti-patterns to avoid using the libraries incorrectly.
