Frequently Asked Questions About Go — Did you know there's an official Go FAQ? It's been around forever, but somehow we’d not run into it it before.. 😅 It’s packed with interesting stuff and worth a flip through. Some of our favorites:

The Go Team

How Grab Uses Its Own Go Module Proxy — The team behind Grab, a popular ‘super-app’ in Southeast Asia, relies on a large Go monorepo for its backend dev projects and they use the Athens Go module store and proxy to make their dev process smoother and, in particular, to reduce module fetching times.

Proposal: Let's Change the pprof Mutex Profile in Go 1.22 — This is, admittedly, a niche topic. The idea is to measure contention based on how many goroutines are blocked on a mutex rather than the number of OS threads (which may be just one). For example, if you hold a mutex for 10ms and several goroutines wait for it, only 10ms total contention would currently be recorded.

▶  MIT 6.824 Distributed Systems — It’s from 2020, but this playlist did the rounds on social media recently and what I’ve watched so far has been good. Prof. Robert Morris tackles the broad concepts of distributed systems, including fault tolerance, replication, and concurrency control. It’s broadly language agnostic, though Go is used for the main coding sections, such as the lecture on building a consensus algorithm in Go.

🛠 Code & Tools

Chroma 2.8: Pure Go Syntax Highlighter — Take source code and turn it into syntax highlighted HTML, ANSI colored text, or just grab the raw tokens in JSON. Brings most of the features of Pygments to Go and can use Pygments’ lexers and styles too. There’s an online playground where you can try it out. v2.8 adds support for ArangoDB Query Language and WebGPU Shading Language, plus more.
