Go Structs and Interfaces Made Simple — An introduction (or refresher) of Go’s core building blocks when it comes to working with data types and structs – an approach that differs somewhat from those favored in object oriented languages like C++ or Java.

Participle: A Simple Library for Defining Parsers — Provides a straightforward yet idiomatic way to define parsers in Go using a familiar approach of using struct field tags to define a grammar, so if you’ve used encoding/json before, you’re well on your way.

DiceDB: A Reactive, In-Memory Database Optimized for Modern Hardware — A new Go-powered database! Dice is a reactive database where your clients subscribe to receive changes immediately and it seems to take a lot of inspiration from the Redis approach being both in-memory and with simple Redis-like commands. GitHub repo.

Why Reimplement TypeScript's Compiler in Go? — Many people have been asking why Microsoft is porting TypeScript’s compiler to Go rather than, say, Rust or C#. TypeScript’s architect Anders Hejlsberg delivered the definitive comment on the matter: Go fit the technical requirements and proved the best high performance language to which to port JavaScript for a variety of reasons.

TypeScript's Compiler to Get 10x Faster, Thanks to Go — TypeScript has shaken up the JavaScript ecosystem in recent years with an increasing number of developers relying on its strong typing and added structure. TypeScript’s compiler isn’t particularly fast, though, but the TypeScript team at Microsoft is changing that by porting it to Go!

New Low-Level Tools for Garbage Collection Efficiency — A look at two new features offered by Go 1.24’s garbage collector: runtime.AddCleanup and weak.Pointer. Cleanups are like finalizers, but get around some of their quirks by not resurrecting objects they’re attached to. Weak pointers, meanwhile, let you reference objects without preventing their garbage collection.

Different Ways of Working with SQL Databases in Go — Starting with a simple schema presenting a basic blog system, Alex walks through a variety of approaches from working with raw SQL and database/sql to sqlx, using ORMs, and sqlc.

Building a Secure Session Manager — The stateless nature of requests to a webapp demands some sort of session management, most commonly via a cookie containing a unique ID to identify the user. Mohamed looks at a way to keep this whole process secure.

Using Cursor for Large Projects — If you’ve tried using tools like Cursor to write Go code in larger projects, you’ll have almost certainly run into its limitations. Thierry has some tips for adding a bit of structure to the ghost in the machine.

Sign Up for a Workshop to Get Started Building Go-Powered Decentralized Apps — App builders, Go enthusiasts, tinkerers: come and build on gno․land, a smart contract platform for a freer, fairer world.

RobotGo: Native Cross-Platform GUI Automation — A way to control the pointer, keyboard, read the screen, etc. Combine this with an LLM perhaps.. if you dare?

ghw 0.15.0: A Go Hardware Discovery/Inspection Library — Find out things about the memory, CPU, storage, network support, and similar things about the host computer. Focused on Linux and Windows, with partial macOS support.

ObjectBox Go 1.9: A Fast, Embedded Database for Go Objects — Store objects in ObjectBox and find them again using powerful queries.

Keep Postgres Maintenance from Slowing Down Your Go App — Secure your spot to learn the proactive maintenance practices that uncover hidden database performance risks, like slow queries, checkpoint behavior, & connection issues, before they escalate.

Tips to Debug Hanging Go Programs — Next time your Go app becomes unresponsive, these tips can help you find the issue by forcing a stack trace or using Delve to attach to the process (or core dump) and revive the program.

Calling Rust from 'Cursed' Go — Cgo is Go’s mechanism for calling external/foreign functions but its performance often causes consternation. Enter purego, a still-in-beta way to make such calls without Cgo.

Nil Channels in Go — Nil channels seem to baffle many Gophers, so Vishnu went on a quest to figure out why in a particular case. This led him to the wisdom of a new Go proverb: “Init when you split; Nil when you merge.”

The Magic of Small Engineering Teams — How PostHog uses small teams to ship fast and scale at the same time.

Gore 0.6: A Full Featured Go REPL Environment — You get all the niceties you’d expect like line editing, history, multi-line input, the ability to import packages, and, in this latest build, gopls-powered code completion too.

Go Clean Template — Inspired by Uncle Bob’s ‘Clean Code’ principles, this repo attempts to provide a ‘clean architecture template’ for building Go-powered services that are well organized and won’t turn into a mess. You be the judge.

go-git 5.14: An Extensible Git Implementation in Pure Go — “Manipulate git repositories at low level (plumbing) or high level (porcelain), through an idiomatic Go API.” Now requires Go 1.23+.

sqldef 1.0: Idempotent Schema Management for Databases — A Go-powered CLI tool and WASM library for diffing SQL schemas (demo here). Supports MySQL, Postgres, SQLite and SQL Server. Built by one of Ruby’s core team members, too.

The Cost of Go's panic and recover — When something goes unexpectedly and critically wrong in a Go program you might use panic to abort things quickly, but did you know you can use recover to manage what happens after a panic? This means you could use it as a sort of control flow mechanism, if you were in a particularly unorthodox mood..

Faster Go Maps with Swiss Tables — One of Go’s newest features is a revamped map implementation powered by a new hash table algorithm called Swiss Table that boosts map operations up to 60% faster in microbenchmarks, while reducing memory overhead. Here’s a look at how it works.
