Many aren’t well documented, but can have striking effects, such as `nosplit` which can offer a performance boost in certain scenarios, but may also lead to faults or a locked runtime. This is, nonetheless, a fantastic explainer. Miguel Young [Generic Interfaces](https://go.dev/blog/generic-interfaces) — Axel presents the idea that as interfaces are types themselves, they too can have type parameters. He shows how this lets you write one core implementation of a binary search tree and support built-in, callback-based, or method-based comparisons, before moving on to deeper concepts. There's a lot to get your teeth into here.

[Serving 200 Million Requests Per Day with `cgi-bin`](https://jacob.gold/posts/serving-200-million-requests-with-cgi-bin/) — [CGI](https://en.wikipedia.org/wiki/Common_Gateway_Interface) was commonly used in the earlier days of the Web to have HTTP requests launch backend processes and return the results. Over time we moved onto persistently-running apps, but could the speed of Go and launching processes in 2025 make `cgi-bin` viable again? Yes! (But you might not want to..)
