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...

▶  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.

pg_flo: Stream, Transform, and Route Postgres Data in Real-time — Offers a set of filters and transformations that can make moving data between, say, production and staging databases simple using one of two modes: copy-and-stream or stream-only. Uses NATS and Postgres’s replication.

yq: Portable CLI YAML, JSON and XML Processor — jq is a popular tool for working with JSON from the command line – yq takes a similar idea to even more formats. Plus it's built in Go!

Awesome Go: Almost 3000 Categorized Go Resources — A perennially useful resource that continues to get frequent updates (almost non-stop), and well worth revisiting in this quiet week for Go. You can contribute projects of your own to the list too.

Writing Benchmarks: Performance Testing in Go — A handy article that lays out all that’s possible with Go’s benchmarking tests. After reviewing the tool’s myriad parameters, Willem provides a full repo-backed example to show it off in action.

▶  🤖 Exploring AI-Powered Solutions with Ollama and LangChain Go — Ollama is used to run open source large language models locally and LangChain Go makes it easy to build Go-powered apps that lean on such LLMs.

Why Go Developers Should Try Odin — Odin is a lesser known but well featured programming language that the author says is part Go and part ‘features you wished Go had’. It’s worth having on your radar even if you don’t adopt it.

'Jia Tanning' Go Code — 'Jia Tan' here refers to essentially ‘backdooring’ a codebase with code that appears to be test code but isn’t, by the use of sneakily formatted filenames.

GitHub repo.

go-graphviz: Go Bindings for Graphviz — Graphviz is a popular open source graph visualization toolkit and this library lets you use it from Go by way of a cross-platform friendly WebAssembly build.

Viddy 1.2: A Modern Go Alternative to watch — viddy can execute commands on a periodic basis but you get niceties like ‘time travel’, attractive output, and paging. Plus a bit of A Clockwork Orange thrown in.

Speeding Up Calculations 450% with Go Assembly — Go’s assembler is heavily inspired by Plan 9’s (with Rob Pike and Ken Thompson, along with others, creating both). The author investigates using Go’s assembler to implement a particularly speedy SIMD (Same Instruction Multiple Data) library for Go. There’s also an interesting thread on Hacker News where Russ Cox (as rsc) adds some context.
