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).

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.

In many languages, on of the things I find myself doing is maping over a list to extract some field. For example, coverting a []Person to []Name. Most languages these days have ways to do this pretty easily: Kotlin: people.map { it.Name } JavaScript: people.map(p => p.Name) Rust: people.map(|p| p.Name) Scala: people.map(_.Name) With generics, Go finally can do this in a type safe manner: Map(people, func(t Person) string { return t.
