In this blog post, I'll explain why your logger belongs in the context, share my favourite package and provide some code snippets to get you started.

Always choose the right tool for the job? Nah. I know Go quite well, and I use it wherever I can. Want to find out why?

Shows how much the performance of Go has improved from version 1.0 through to 1.22 (including PGO) -- in its compiler, runtime, and libraries.

I made up a neat little pattern in Go the other day. It’s a way to represent a state change in a system by exposing different APIs for different states, while only holding state in a single underlying struct. I’m sure I’m not the first person to invent this, and it may already a name, so please let me know if you know of one. I’m going to show an instance of the pattern first and the motivation after.

Go first came onto my radar about 9 years ago when I came across MuMax during my PhD studies. While I’ve touched it briefly, I wouldn’t consider myself to have used it in anger until recently, when I started a job that uses it as one of it’s primary languages for API development. I’ve had experience in writing C and C++ code, but more recently I’ve done a lot of Python, so going back to Go has felt oddly like a throwback to those compiled languages I’ve used before, with a bit of modern sparkle.

It may seem silly, but go run is my favorite part about go. Want to run your code? go run main.go. It is so stupidly simple that I could tell my mom about this command, and she would immediately understand. Like with most things in go, the real power in this command is in the effortless understanding of how to build and run everyone’s code. But I can run node main.

In response to @cadey@pony.social's blog post about wanting retry loops in #Golang, I wrote terrible hack using using the proposed iterator syntax. https://go.dev/play/?v=gotip var err error for range backoff(&err, 1 * time.Second) { if err = something1(); err != nil { continue } if err = something2() ; err != nil { continue } }

I wish Go had a retry block https://xeiaso.net/blog/2024/retry-block/
