Go's Error Handling is a Form of Storytelling — That’s probably one of the kindest ways I’ve heard Go’s approach to error handling described, but the author makes the argument that good error messages add up and tell a story.

Preslav Rachev

Staying on the theme of errors, Dolthub's Max Hoffman also wrote about where panics have their place, how panicking is faster than raising errors, and the tradeoffs you need to consider between the two.

Try GoLand 2023.1! — This version introduces the vulnerability checker and better navigation through gRPC code. We’ve also updated the Code Vision feature so that GoLand now shows both the number of implementations for an interface and its method specifications.

Improving Tailscale via Apple’s Open Source — This is only related to Go in as much as Tailscale’s client is written in it, but it’s an interesting tale of how digging through some of Apple’s code has paid dividends in improving Tailscale’s own functionality.

Mihai Parparita (Tailscale)

Tailscale's Jordan Whited also wrote about optimizations made to push Tailscale into the '10Gb/s club' and where some loop unwinding in Go helped.

The Tao of Go — “If we were to approach software development in Go in a sensitive, intelligent way, following the natural contours of the language and the problem rather than trying to bulldoze them out of the way, what would that look like? Let’s try to establish a few general principles.”

IN BRIEF:

Brian Candler has begun putting together a brief guide to laying out different types of Go project.
GitHub has announced that code scanning default setup is now available for Go code (with Go joining JavaScript, Python and Ruby in this regard).
The Go Time Podcast featured a chat with Matthew Boyle ▶️ about domain driven design in Go.
⚡️ It's good news for TinyGo in this paper on embedded language performance on the ESP32 platform where Go even outperformed C/C++ code in some cases, "demonstrated jitter-free execution", and is "more preferable for hard real-time applications." WiFi support remains an issue, however.
Filippo Valsorda looks at the background to a crypto/elliptic vulnerability (now fixed in Go 1.20.2.)

An Indepth Look at Go's Windows Calls — After analyzing a variety of Go malware, the author ended up picking up a lot about how Go calls Windows’ APIs under the hood. This is detailed and not for the faint of heart.

How Go Fixed Everything That Was Wrong with Programming — A bold claim, but unsurprisingly this is an opinion piece ;-)

🛠 Code & Tools

llama.go – It's Like llama.cpp in Pure Go — This is exciting, but there’s a lot to unpack if you’re not into modern large language models. If you’ve heard of ChatGPT, it relies on a ‘large language model’ (LLM) and LLaMA is Facebook/Meta’s attempt at producing one of their own. llama.cpp is a C++ app to use the LLaMA model efficiently, and now llama.go is a Go attempt. Oh, and you need a lot of memory. Phew.
