Build back bitter

[Greg Molnar @GregMolnar]

The latest episode of the Pingback Podcast with @joelga is out!
We had a special guest this week! @samruby has more years of programming under his belt than I have lived!
His recent project Roundhouse is having a good momentum. Go and give a listen!

Did not expect a question that starts out 'Do you think before you speak?' to go so well. A+ question from Charlotte Harpur A++ response from Eileen Gu.

@josevalim @roguewealth try my project agent mvc https://t.co/e7GRzL0xO1 it has a language agnostic conformance spec.

[Ruemic @Ruemic]

do it @josevalim !

[Sam Ruby @samruby]

Would you be willing to look into Roundhouse? I'm willing to spend the tokens with you guiding the effort.

[Ruemic @Ruemic]

@largo Totally, get in on the action! Have you tried compiling anything yet? The project is very accessible.

[Ruemic @Ruemic]

@hopsoft Spinel + Roundhouse is incredibly exciting. It's absurdly ambitious in just the right way and very open to open source contribution. Join the party. I'm committed to getting BitterClip to compile, which 3 million lines Rails!

@mikehostetler @thorstenball https://t.co/TTSGuBJpjO any feedback on this, I’m trying to basically have one prompt per language+framework that represents how an expert in the framework would guide the agent to build conduit ( the spec app being compared )

[Ruemic @Ruemic]

I am publishing archives of agents one shotting a spec app at https://t.co/8zblh6el25 and I would be super honored if you could make a PR for the elixir prompt. Basically I’m just trying to have an even playing field where there’s a expert level prompt for each language to make it as terse and idiomatic as possible, and a shared spec they need to hit.

[José Valim @josevalim]

Do you have the prompts or threads publicly available?

The agent clearly chose to follow Rails compatibilty more closely in the Elixir version. So a few of Rails limitations got ported to the Elixir one. Here is an example from the README itself:

> Elixir retains Redis and Resque-compatible jobs, while Rust uses integrated queues and a different frontend/server implementation.

The agent knows, it just chose to prioritize something else, which will always happen if you are not steering.

I am certain coding agents can spot those issues and bring the numbers up for both Elixir and Go with no troubles whatsoever (although I don't expect them to beat Rust).

[Ruemic @Ruemic]

I’ve got a project that’s similar but attempts to be more rigorous by defining a spec. They must all share so the app has the same requirements across the different languages https://t.co/8zblh6el25 I’m seeing similar performance on the compiled with Spinel Ruby as the Rust version

what you don’t realize

is _why wrote a very good DSL 19 years ago

and every agent alive today has been trained on every bit of it

@alihfadel @yukihiro_matz truly genius marketing

[Ruemic @Ruemic]

Initial explorations with Spinel are very promising! Seeing around 6x+ perf And request throughput on the canonical https://t.co/e7GRzL0xO1 app! It wasn't easy, but it works! 2 PR's landed upstream, lots more incoming.

[Ruemic @Ruemic]

@yukihiro_matz @dhh I kneel before thee

[Ruemic @Ruemic]

🔥🔥🔥 this whole thing has been a good cop, bad cop routine the whole time hasn’t it?

[Yukihiro Matz @yukihiro_matz]

@dhh Campfire compiled with Roundhouse + Spinel runs 5.4 times faster in rps, and consumes 1/12 of memory. No modification needed.
