Understanding the Go Scheduler
(nghiant3223.github.io)
Understanding the Go scheduler is crucial for Go programmer to write efficient concurrent programs. It also helps us become better at troubleshooting performance issues or tuning the performance of our Go programs. In this post, we will explore how Go scheduler evolved over time, and how the Go code we write happens under the hood.

Leak and Seek a Go Runtime Mystery
(cyolo.io)
"We think we have a problem." That's how the conversation with the customer success team started: A polite heads-up about a potential memory leak by the platform team. Little did we know, we were about to embark on a debugging adventure worthy of any great detective novel. Within hours, three of our largest customers were reporting significant performance issues. Clearly, this wasn't just "a problem." It was a full-blown crisis.

Proposal: Add bare metal support to Go
(github.com/golang)
I propose the addition of a new GOOS target, such as GOOS=none, to allow Go runtime execution under specific application defined exit functions, rather than arbitrary OS syscalls, enabling freestanding execution without direct OS support.

Runtime: Green tea garbage collector (Go)
(github.com/golang)
This issue tracks the design and implementation of the Green Tea garbage collector. As of the last update to this issue, development of Green Tea is still active. We'll produce more detailed design document once we're ready to commit to a design. For now, Green Tea is available as an experiment at tip-of-tree and is planned as to be available as an opt-in experiment in Go 1.25, once it releases. We encourage teams to try it out.

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.

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

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.
