- April 2026 I’ve been having moderate success using an AI agent to help me fix non-trival bugs in GoAWK. But it’s sometimes very indecisive (Mitchell Hashimoto noted this in a tweet just the other day). I asked it the following question (I’m using Claude’s Opus 4.6 with the...

- Creating a subset of Go that translates to C was never my end goal. I liked writing C code with Go, but without the standard library it felt pretty limited. So, the next logical step was to port Go's stdlib to C.Of course, this isn't something I could do all at once. I started...
- What a month! After losing a job at the end of January, I started looking for a new one straight away. Seeking a new job nowadays is very different from how it used to be. Very long, multi-step and mentally draining processes are the new norm. The recent explosion of AI tools...

- I'm working on a new programming language named Solod (So). It's a strict subset of Go that translates to C, without hidden memory allocations and with source-level interop.Highlights:Go in, C out. You write regular Go code and get readable C11 as output.Zero runtime. No garbage...

- How many millions of times have you seen this pattern in Go where a variable is pre-created just to make a pointer to it down the line? There is a high chance your codebase includes a utility to do that. // Something like this a := 123 aPtr := &a // Or like this func Pointer[T...

- I’ve been exploring Go for building small, fast and self-contained binary applications recently. I’m enjoying how there’s generally one obvious way to do things and the resulting code is boring …
- Go has several ways of sending requests, including some convenient methods such as:http.Get()http.Head()http.Post()http.PostForm()However, these don’t let you add headers to requests! If you need customization of the HTTP method or headers, you need to use...
- Basic Usage of time.Sleep()You can use time.Sleep() to pause your program for a predetermined amount of time, similar to most programming languages.First, you should know that the time package has useful constants that allow you to conveniently specify time in units.1 2 3 4 5 6...

- Everyone likes interfaces in Go and traits in Rust. Polymorphism without class-based hierarchies or inheritance seems to be the sweet spot. What if we try to implement this in C?Interfaces in Go • Traits in Rust • Toy example • Interface definition • Interface data • Method...
- Go 1.26 is coming out in February, so it's a good time to explore what's new. The official release notes are pretty dry, so I prepared an interactive version with lots of examples showing what has changed and what the new behavior is.Read on and see!new(expr) • Type-safe error...
