Proposal: Add Region-Based Memory Management to Go — If you have a long memory you might recall an indefinitely stalled proposal for adding memory arenas to Go. This new proposal comes up with a differently scoped alternative, based around regions, and has attracted a lot of comments both in support of and against the idea.

Polyglot Programming: TypeScript, Go, & Rust — A mind-bending tutorial journey about programming side-by-side in these three languages. This detailed video course shares how to get the most out of this multi-language approach, specifically by implementing a fully-unit tested CLI app and comparing the differences.

👀 wasmVision: A Way to Get Go-ing with Computer Vision — Fresh from the genius behind TinyGo and GoCV comes a high-performance computer vision processing engine you can customize and extend with WebAssembly (which you can generate with TinyGo – or Rust or C, if you're so inclined).

fmt.Sprintf vs String Concat — While code using fmt.Sprintf might look better-structured, simple string concatenation (+) proves to be somewhat faster. Why? Max digs into how fmt.Sprintf works under the hood.

Go Runtime Finalizer and Keep Alive — A look into Go’s runtime.SetFinalizer and runtime.KeepAlive APIs, two advanced features that have some interesting quirks and should be used cautiously. Finalizers are notoriously problematic (and may even be deprecated one day) while KeepAlive is easier to grok but will stop objects from being collected.

Creating a 'Brainrot' Language Server in Go — So-called ‘brainrot’ is a mishmash of next generation slang and memes. Follow along with this tutorial as the rizzler Jitesh creates a bussin' basic LSP server – no cap. Perhaps you can put the lessons learnt to more productive use? 😅

Machine Learning in Go with a Python Sidecar — While Python currently holds the ML crown when it comes to the diversity of projects and examples, Go is a great ‘glue’ language for working with ML and LLMs and tying things together, even if it involves talking to Python-based projects.

🕒 When 1.1: Natural Language Date/Time Parser — A very long standing, and useful, library. The idea is simple: given a string like “tonight at 11:10 pm” or “next wednesday at 4:20 a.m”, you get the date/time you expect. Has rules for English, Portuguese, Chinese, Russian, and Dutch out of the box.

html-to-markdown 2.1: Convert HTML to Markdown — Actually parses HTML rather than just using regexes so can handle a lot of interesting edge cases. v2 is a total rewrite and boasts improved accuracy. It can be used both as a CLI tool or Go library. GitHub repo.

Reduce Your Apache Kafka Costs by 80+% — Kafka with no local disks or interzone fees, zero ops auto-scaling and in your cloud with no cross-account access.

Yokai: A Modular, Observable Go Framework for Backend Apps — A modular framework for production-grade Go backends that handles observability, configuration, and dependency wiring out of the box, meaning less infrastructure boilerplate for you to write.

Happy Birthday, Go! Go Turns 15 — Grab a slice of cake, Go has celebrated its latest anniversary. Austin reflects on what Go’s latest year has brought to the language and what the ongoing priorities for the core team are.

How to Compare Postgres EXPLAIN Plans & Tune Slow Queries — Are slow Postgres queries impacting your Go app performance? Join this webinar to learn how to diagnose and tune them effectively. We'll use pganalyze to walk through how to compare plans & debug common scenarios like inefficient nested loops & missing indexes.

Checking the Top 10 Million Web Sites with Go — Actually titled ‘27.6% of the Top 10 Million Sites are Dead’, I felt this is really more a look into using Go to do basic scraping at scale. Redis was coupled with Go (along with a lot of hardware) to perform the task in just ten minutes (~17k requests per second). The source has...

Ranging Over Functions in Go 1.23 — This post discusses several examples of using the new range-over functionality in 1.23, including simple linear iterators, recursive iterators, and a brief word on push vs pull iteration.

▶  The Business of Go — I often skip high level talks to focus on technical ones, but Matt Boyle encouraged me to watch this, and it’s an interesting look at the processes of the Go team and how Go gets treated as a product, rather than just a language. Cameron demonstrates why Go continues to grow and thrive in a space where it’s easy...

Creating a Full-Stack App with Go and React — A look at bringing together the best of the front end and back end into a single app, a contrived ‘Go Eats’ food ordering service.

Constraints in Go — John has finished his 4-part series on generics (which started here) with a look at placing constraints on types.

Building Thread-Safe Abstractions in Java vs Go — A look at translating pieces of the SimpleDB implementation from Java into Go, and differences between the concurrency and synchronization primitives the languages provide.

The First Newsletter Dedicated to Product Engineers — Learn the skills and strategies the new generation of product engineers need to succeed.

vgt: The 'Missing Tool' for Visualizing Go Tests? — A browser-based tool for visualizing Go test results – described as being helpful for understanding the parallelism of tests along with identifying slow ones.

jsony: A 'Blazing Fast', Safe JSON Serialization Library — Pure Go, reflection free, and faster than the stdlib approach, but you do have to lay everything out just right.

Writing Secure Go Code — A handy article rounding up a variety of resources and techniques to keep in mind in order to write more robust and secure Go apps, including staying up to date with your Go version, leaning on Go’s tools like go vet, and scanning your code for known vulnerabilities.
