Go Generics: The Bottom Line

To give you a bit of context, I have been running a version of generic type parameters in Go in production for a few months. I have had a chance to try a few things and see what works and what doesn’t. Prior to that, I’d spent a

S, E, and H

What I realized over time: The S in Python stands for “Slow.” The E in Go stands for “Easy.” Also: The H in Rust stands for “Hard.” Moral: the common perception about things is deceptive. Labels are limiting. Trust your own intuition and understanding.

Erlang vs. Go vs. Rust

Erlang: Let the process tree crash. The BEAM will take care of restarting it. Go: Panic and let the app crash. Systemd, Docker, or Kubernetes will take care of restarting it. Rust: If you actually make the app compile, it might possibly run forever. Infinite success 🤣 Have something to add?

What instead of Why ...

It's ironic how many articles, whose titles begin with "Why ...", totally flip the story into answering the "What" instead. The end result is a swath of mediocre content that's just a restatement of other mediocre content. No traces of reasoning or critical thinking whatsoever.

Interpreting "expectations for generics in Go 1.18"

Sometimes, I feel like I don't quite understand the core Go team's writings. I don't mean this in a bad way, though. We are computer scientists by nature, not craftsmen of prose. And yet, I have this feeling that we could strive to do a better job at communicating our

Fake news is not meant to change minds.

Fake news is not meant to change minds. It’s about strengthening the wrongly-rooted beliefs some of us already have. This is the reason why and how filter bubbles originate. Each and every one of us profoundly believes in multiple things, many of them with varying degrees of truth. To

Generics Need Standard Library Support From the Start

Among the first things that once drove me to try Go was a video by Rob Pike, called "Simplicity is Complicated." In it, he describes at length that one of Go's unique differentiating features is its core team's obstinance to conform to community pressure and adding new features. A couple
