+
+YS is a YAML loader module.
+On one hand it does have super powers,
+but on the other hand it's just a plain YAML loader.
+
+A YAML loader is a utility that can turn YAML into a data structure.
+Every modern language has a YAML loader.
+Most have many.
+
+YS is the first YAML loader that was made for every programming language.
+
+Well that's the goal anyway.
+
+For the past year it's only had loaders for 11 languages:
+[Clojure](https://clojars.org/org.yamlscript/clj-yamlscript),
+[Crystal](https://shardbox.org/shards/yamlscript),
+[Go](https://github.com/yaml/yamlscript-go),
+[Java](https://clojars.org/org.yamlscript/yamlscript),
+[Julia](https://juliahub.com/ui/Packages/General/YAMLScript),
+[NodeJS](https://www.npmjs.com/package/@yaml/yamlscript),
+[Perl](https://metacpan.org/dist/YAMLScript/view/lib/YAMLScript.pod),
+[Python](https://pypi.org/project/yamlscript/),
+[Raku](https://raku.land/zef:ingy/YAMLScript),
+[Ruby](https://rubygems.org/search?query=yamlscript), and
+[Rust](https://crates.io/crates/yamlscript).
+
+Until this week, that is...
+
+<!-- more -->
+
+
+## This week it got four more!
+
+* [C#](https://www.nuget.org/packages/YAMLScript/)
+* [Haskell](https://hackage.haskell.org/package/yamlscript)
+* [Lua](https://luarocks.org/modules/ingy/yamlscript)
+* [PHP](https://packagist.org/packages/yaml/yamlscript)
+
+The YS language bindings are fairly simple.
+
+They are each an FFI binding to the `libys` shared library.
+
+Codewise they are only ~100-200 lines of code in any given language.
+
+In the past the YS team would find a person who was proficient in a language to
+write the binding.
+
+This week we decided to try a little AI.
+
+I wouldn't say it was a completely smooth process.
+Each one took several hours to complete.
+
+But in the grand scheme of things, if you can support a new language in a day,
+that feels like a win.
+
+
+## 42 Languages
+
+From the start of YS, the goal has always been to support at least 42 languages.
+
+Rosetta Code currently claims to have 973 languages.
+
+But I'm talking about languages that at least support JSON and have a library
+registry or package distribution system.
+
+I have a list of 45 candidate languages, each with a different registry, so I'd
+say 42 is a reachable goal.
