An Introduction to Go's Profile-Guided Optimization — What if the Go compiler could improve how it compiles software based upon real-world profiling? Profile-Guided Optimization (PGO) feeds runtime profiles to the compiler to optimize the binary based on usage. Go 1.20 includes initial support for this, so try this with your apps and (hopefully) see some perf gains.

Transparent Telemetry for Open Source Projects — It's an emotive topic, but Russ puts forth a concept of ‘transparent telemetry’, a privacy-sensitive approach to gathering usage data in the Go toolchain to help Go library devs, the core team, and others. There’s a lot to unpack and there's a a GitHub discussion where you can have your own say (as things stand it has 144 👍 and 449 👎…)

Russ Cox

Russ also has a use cases post which might help win you over or at least realize there are things that surveys alone cannot capture. He makes a compelling case.

User or *User - Do We Need Struct Pointers Everywhere? — The answer, as you might’ve guessed, is “no.” But, it’s also more nuanced due to the lifetime of a struct, its usage, and other aspects that boil this down to general guidelines and case-by-case analysis.

🔠 Go's not just a language..

It's also a typeface! You may or may not recall that back in 2016, the Go team announced the release of the Go fonts, available in both proportional and monospace variants.

If you want to give them a Go for yourself, they're located alongside Go's image libraries and you can get them like so:

git clone

The TTF files are then located at: image/font/gofont/ttfs
