Not my proudest work, but I needed a quick shell script. I’ve been diving deeper into Matrix bridges lately — those connectors that let Matrix users communicate with other platforms like WhatsApp, Telegram, Discord, Slack, and more. In doing so, I’ve learned a lot about how these bridges are built, deployed, and maintained. The twist? I’m running everything on OpenBSD. Running -current on OpenBSD is great, but it does mean I often need to compile packages faster than the official rele...| geekyschmidt.com

This morning a one line change had several of us tearing up the fabric of reality trying to understand why a failing test wasn’t failing, or, in fact, being run at all.

Today’s post comes from a recent Go pop quiz. Consider this benchmark fragment. A convenience wrapper around sort.Sort(sort.StringSlice(s)), sort.Strings sorts the input in place, so it isn’t expected to allocate (or at least that’s what 43% of the tweeps who responded thought). However it turns out that, at least in recent versions of Go, each […]| Dave Cheney

A few days ago Fatih posted this question on twitter.

Conventional wisdom dictates that the larger the number of types declared in a Go program, the larger the resulting binary. Intuitively this makes sense, after all, what’s the point in defining a bunch of types if you’re not going to write code that operates on them. However, part of the job of a linker is […]| Dave Cheney
Programmers have a tendency to be superstitious. Particularly, when a programmer hears that copies are expensive, they start to see them everywhere, especially when they learn that, in Go, every assignment is a copy. Consider this code; x is three orders of magnitude larger than y, is the assignment of x to a more expensive […]| Dave Cheney

This is a thought experiment in API design.

The assertion. if err != nil { ... } is repetitive and in the […]| Dave Cheney

A few weeks ago Anton Zhiyanov published the blog post Expressive tests without testify/assert. It's a good and well thought-out post, and I recommend giving it a read if you haven't already. In the post, Anton makes the argument for not using packages like testify/assert for your test assertions, and instead creating your own minimal set of assertion helpers to use in your tests. In fact, so minimal that there are only 3 helpers he uses: AssertEqual, AssertErr and AssertTrue.| www.alexedwards.net

Viewstamped replication(VR) is a replication technique that takes care of failures when one or more nodes end up crashing in a cluster. It works as a wrapper on top of a non-distributed system & allows the underlying business logic to be applied independently while the protocol itself takes care of replication. The protocol was introduced in the paper and then was revised with a set of optimizations under a new paper known as Viewstamped replication revisited. | Distributed Computing Musings

When I'm building a web application in Go, I prefer to use command-line flags to pass configuration settings to the application at runtime.
