Interesting, came across another ‘typed’ Ruby - https://github.com/type-ruby/t-ruby
Seems similar to couple of other attempts (emits RBS), eg myrb and claret

In addition to new language features
* Lots new in the threading chapter, including Ractor updates and a section on concurrent-ruby and Async
* The typed Ruby chapter has a section on Literal
* Lots of small cleanups and updates

We were very proud to present @marcoroth.dev with the Rails Luminary Award 2025.
And yes, I was on a secret mission to Zurich 😀.

LLM agents are taking over so have decided to split my personal computing from work related (ie for privacy, data security etc)
Just received my little work machine, a Ryzen 9950X with 64GB RAM, should speed up the test suite runs at least!

Also includes a simple 'type tracer' that agents can use to help explore method return types at runtime.

Next gem to get a v1 will be https://github.com/stevegeek/typed_operation
Its a 'command pattern' (aka callable/service object/???) gem, operations can be partially applied, curried and have typed parameters. Auth via action_policy if desired
Now adding last things: chaining and instrumentation

Got bombed with random bot requests for .js files on a Rails app. The Ruby processes pegged at 100% CPU. Think it was cause Rails was raising and logging large number of ActionController::InvalidCrossOriginRequest exceptions. Time to add that missing `rescue_from`

Been finding optimising sqids-ruby and hashids.rb interesting. Wonder if I should turn the experience into a talk proposal for a conference... ie we live code through finding hotspots in some gem, try optimisations and consider why result performs better or not, and trade offs vs readability etc ? 🤷

Sick of looking up `find/exec` syntax on stack overflow? I built detect as a replacement:
```
cargo install detect
detect 'ext in [rs, ts, js] && size > 0.5mb && modified > -7d'
detect 'ext == ts && content ~= class.*Service'
detect 'name == "Cargo.toml" && toml:.package.edition == 2018'
```
```

Straight away Herb found 7 erb files with missing closing tags in the HTML and approx 130 linting errors such as missing alt tags, pointless use of `-%>`, anchor tags without an `href` etc.
And parses all 555 erb files in 3-4 seconds.
Really cool!

Also coming in Herb v0.8.0, the long awaited Tailwind CSS class sorting feature in the Herb Formatter! 🌿
Here is a demo of that working in @zed.dev using the new `.herb.yml` configuration file! 😍

I was recently thinking about adding benchmarking across multiple Ruby versions with my `awfy` tool, and this looks perfect for managing that!

TIL `Symbol#name` returns a frozen string representation of a Symbol while `Symbol#to_s` returns a mutable String, resulting in a significant performance difference. For some reason I assumed they were the same.

If you are looking to use your voice more over typing for work (e.g. for RSI reasons), I highly recommend superwhisper.com ... seems to work very well with technical terms.

In the upcoming Herb v0.8.0 release, the Herb Linter will support a new `--fix` option to autocorrect offenses.
This isn’t dependent on the Herb Formatter and uses the `printer` architecture, so the Linter can fix only the offenses without touching anything else in the document!
