Ask HN: What is the coding exercise you use to explore a new language?

• odin_rosettacode

  1 3 10.0 Odin

  Odin examples for Rosetta Code

If the language isn't well represented yet on rosettacode.org I like to learn about a language by implementing rosettacode examples in it: https://github.com/eterps/odin_rosettacode

• Rustlings

  289 49,011 9.3 Rust

  :crab: Small exercises to get you used to reading and writing Rust code!

  

I usually pick one of the ideas on my low-stakes "side quest" list that I maintain. Something that I won't mind if it never gets finished, or if I have to trash it and start over because of what I learned while building it the first time, now that I know the language better.

I'm picking up Rust, and I really like the "rustlings" project that lets you exercise various parts of the language locally, instead of in a browser, so I can use the tools that I like. https://github.com/rust-lang/rustlings

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• johnston

  2 4 10.0 Rust

  Rust utilities for working with Just Intonation tuning systems

- how easy is it to write/run tests

Here’s one version in Rust, which links to clojure, cl versions. Want to try it with Julia next due to the built-in support for rationals.

• ziglings

  36 4,085 8.1 Zig

  Learn the Zig programming language by fixing tiny broken programs.

+1 for rustlings, which also inspired "ziglings" [1]. Both of these were great resources for quickly & easily learning the basics of their respective languages.

• pbrt-v3

  16 4,818 2.3 C++

  Source code for pbrt, the renderer described in the third edition of "Physically Based Rendering: From Theory To Implementation", by Matt Pharr, Wenzel Jakob, and Greg Humphreys.

• Taipei-Torrent

  1 837 10.0 Go

  A(nother) Bittorrent client written in the go programming language

I typically only use the spec (https://www.bittorrent.org/beps/bep_0003.html) because it's simple enough, but in case of doubt I guess a third party resource is good. I found https://blog.jse.li/posts/torrent/ to be quite informative about it.

I used to work on a fork of https://github.com/jackpal/Taipei-Torrent with custom features, I found its code to be easy enough to understand
