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/

I strive to respect everybody’s personal preferences, so I usually steer clear of debates about which is the best programming language, text editor or operating system. However, recently I was asked a couple of times why I like and use a lot of Go, so here is a coherent article to fill in the blanks of my ad-hoc in-person ramblings :-).

Today, if you publish a popular Go module on a URL and you lose control of the URL (through, eg, domain expiration and having the domain snatched up), you have a problem that's probably more or less impossible to deal with short of making blog/Fediverse/etc posts about the situation. Go module identity is tied to URLs with more or less no external override or way to automatically announce and see problems (individual people can override for their usage, but that doesn't scale).

Ok, I lied, there's no weird trick. However, you can easily reduce a Go binary size by more than 6 times with some flags and common tools. Note: I don't actually believe a 30MB static binary is a problem in this day and age, and I would not trade (build

Go&rsquo;s <code>defer</code> and <code>t.Cleanup</code> have similar semantics, but there&rsquo;s a good reason to prefer the use of <code>t.Cleanup</code> specifically in the presence of parallel subtests.

Amazon Web Services (AWS) is deprecating the go1.x runtime on Lambda, this is currently scheduled for December 31, 2023. Customers need to migrate their Go based lambda functions to the al2.provided runtime, which uses Amazon Linux 2 as the execution environment. I think this is a bad thing for a couple of reasons: There is no automated migration path from existing Go Lambda functions to the new custom runtime. Customers will need to manually refactor and migrate each function to this new runtime, which this is time-consuming and error-prone.

How and why we started annotating all our Go tests with <code>t.Parallel()</code>, and why you might want to consider doing so too.
