Cheating the Reaper in Go

Even though I am a C++ programmer at heart, Go fascinates me for none of the reasons you think. Go has made several interesting design decisions:

HTTP/0.9 from Scratch (2024)
(kmcd.dev)
Welcome to the first installment of our “HTTP from Scratch” blog series! In this series, we’ll embark on a journey through the evolution of the Hypertext Transfer Protocol (HTTP), the backbone of the World Wide Web. By building simple implementations of each major HTTP version in Go, we’ll gain a deep understanding of how this essential protocol has shaped the internet we use every day and how it has evolved to what we have now.

Layered Design in Go

This post will describe how I design my programs in Go. I needed this for work, and while I searched for a link, nothing quite fits my coding practices out there. The word “Layered” can pull up some fairly close descriptions, but I want to lay out what I do.

Optimizing Heap Allocations in Go: A Case Study

Ask HN: Writing an Interpreter in Go or Crafting Interpreters?

I'm thinking of learning about compilers and am pleased to find that there seems to be at least two very accessible choices, "Writing An Interpreter In Go" and Crafting Interpreters. Curious if folks here have experience with either and could provide recommendations?

Ten Commandments of Go
(bitfieldconsulting.com)
As a full-time Go teacher and writer, I spend a lot of time working with students to help them write clearer, better, and more useful Go programs. I’ve found that a lot of the advice I give them can be reduced to a fairly small set of general principles, and here they are.

Rust is easy? Go is hard?
(medium.com)
I recently had a project pop up where I thought Go would be a really good fit. It’s been a while since I actually have used Go for anything, so I also thought it’d be a fantastic opportunity to practice and not lose those skills. It turns out, Rust is actually easier to use than Go. Here is the story.

Using Signals with Go
(calhoun.io)
Signals are messages that can be sent to running programs, and are often used to request that a program performs a specific behavior. The most common signal is likely the SIGINT signal, which is sent when a developer presses Ctrl+C in the terminal. This signal tells the program to stop running, and is how we terminate a running process.

Rust vs. Go

Which is better, Rust or Go—and does that question even make sense? Which language should you choose for your next project in 2025, and why? How does Rust compare with Go in areas like performance, simplicity, safety, features, scale, and concurrency?

Unit testing using mocks in Go
(golangbot.com)
I generally prefer testing my code without using mocks. For example, if the code is integrated with Elastic Search, I prefer to run a elastic search container locally and test the Go code against that container. But there are some cases where creating a local environment for testing is not possible. This usually happens when integrating with cloud providers. Let’s take the case where the code is creating a AWS s3 bucket.

Faster Shuffling in Go with Batching
(lemire.me)
Go’s rand.Shuffle is a solid baseline, but batching random integer generation can make it much faster. By generating multiple random numbers from a single 64-bit value, we can boost efficiency—by over 2x in our benchmarks.

My pessimism about changes to error handling in Go (but they'll happen)
(utoronto.ca)
I've said in the past that Go is not our language, and I still stand by that. At the same time, the Go developers do eventually respond to the clamour from the community, which I maintain that we've seen with both Go's eventual addition of generics and the change to Go modules and Go dependency handling (where Go started with one story until it clearly didn't work and they had to change). This leads me to two related views.

Faster interpreters in Go: Catching up with C++
(planetscale.com)
The SQL evaluation engine that ships with Vitess, the open-source database that powers PlanetScale, was originally implemented as an AST evaluator that used to operate directly on the SQL AST generated by our parser. Over this past year, we've gradually replaced it with a Virtual Machine which, despite being written natively in Go, performs similarly to the original C++ evaluation code in MySQL.

Golang sync.Pool is not a silver bullet
(wundergraph.com)
When it comes to performance optimization in Go, sync.Pool often appears as a tempting solution. It promises to reduce memory allocations and garbage collection pressure by reusing objects. But is it always the right choice? Let's dive deep into this fascinating topic.

The right way to do data fixtures in Go
(brandur.org)
Every test suite should start early in building a strong convention to generate data fixtures. If it doesn’t, data fixtures will still emerge (they’re that necessary), but in a way that’s poorly designed, with no API (or a poorly designed one), and not standardized.
