rakyll.org is a personal blog at rakyll.org about programming and systems. Since 2014, 40 different Hacker News readers have linked it 47 times, most often “Style guideline for Go packages”. It is still writing: the last post was on 2026-09-22, and you can follow it by feed.
Too few sampled comments (9) to say how often HN recommends it.?
Why HN links it
Jaana Dogan's Go-focused posts on generics, the goroutine scheduler, debugging with core dumps, and testing techniques. Commenters link them to explain how Go works internally and as practical references.
Summarised by Claude from a sample of 9 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
Go does accept pull requests, just not GitHub ones: https://golang.org/doc/contribute.html#Code_review (I don't disagree with the premise though, Go does seem to be less community-driven than Rust; e.g. Rust has 3 mozilla employees in the top 10 contributors for the most recent release[0], where as Go has 9 Googlers in its top 10[1].)

HN discussionYou can certainly use generic parameters in methods—the [T any] just has to be on SomeNonGenericType, even if it's not used inside the type itself https://rakyll.org/generics-facilititators

HN discussionI believe they're talking about the semi-duck typing used in go for interfaces but I'm not certain. Interfaces are implicitly implemented with a runtime check determining whether a type x assigned to interface y is valid.This is why you'll often see an empty declaration in packages for structs intended to implement an interface like so: var _ y = x {} // syntax might be slightly wrong After writing this, I found the…

HN discussionThere's a problem lurking behind this "simple" model: the goroutine you park on that blocking IO operation can't be collected reliably itself. I care about collecting goroutines, and would advocate that everyone should care about this. There's been a litany [1] of blogs about this recently, if anyone doesn't consider this self-evident. It's just systematically sane . Letting goroutines spin off into the distance wit…

HN discussionA good presentation did the rounds a while ago[0] that does a deeper dive but the main things for us are the performance, smaller binaries and the improvements in tooling. The one thing I wish they added though? `go new` and have it initialise a new project structure that stopped tiny package syndrome and bizarre Makefiles in repos!

HN discussionCross posting my comment from the crusty news aggregator site: I liked this blog post and agree with most of it. But I think its section on interfaces is a bit muddled. It links to this article[1] for more advice, and while the article sounds nice in principle from the perspective of someone publishing a library for others to use, I’ve found other techniques to be valuable as well. One technique I’m particularly fon…

HN discussionHaven't tried it personally, but based on a recent article shared at r/golang ( https://rakyll.org/coredumps/ , via https://www.reddit.com/r/golang/comments/6cvtd6/debugging_go... ), delve seems to show the contents of an .s file allright.
