Throwing out this idea, but would you ever consider making your own version of Github?

Am I crazy or is this AI generated?

Parts like `No boilerplate, no imports, no build system. Just Ruby being Ruby.` and `The insight behind Shoes wasn't technical—it was emotional` seem to fit a pattern I frequently see in AI Generated output.

Even the structure of the blog post follows a pattern I see in AI generated text with the section of `Why This Matters`.

rajangdavis — Fri, 09 Jan 2026 20:28:27 +0000

The more I use AI, the more I think about the book Fooled By Randomness.

AI can take you down a rabbit hole that makes you feel like you are being productive but the generated code can be a dead end because of how you framed the problem to the AI.

Engineers need enough discipline to understand the problems they are trying to solve before delegating a solution to a stochastic text generator.

I don’t always like using AI but have found it helpful in specific use cases such as speeding up CI test pipelines and writing spec; however, someone smarter than me/more familiar with the problem space may have better strategies that I cannot of think of, and I have been fooled by randomness.

I have been programming with Ruby for 11 years with most of the time in a professional context. It's my favorite language :).

I don't care much for types, but it can be useful with denser libraries where IDE's can assist with writing code. It has been helpful in my professional life with regards to typed Python and Typescript.

One potential example that would be interesting is utilizing types for reflection for AI tool calling, the python library for Ollama already supports this[0].

It would make it easier to use such tools in a Ruby context and potentially enhance libraries like ruby-llm [1] and ollama-ruby [2].

If it is at all possible, it would be nice to have a little bit better support for metaprogramming namely around `define_method` and supplying a typed lambda or block for the dynamic method. I can see why this would be a pain to implement, so I don't expect it :).

Otherwise, I think in terms of typed Ruby, this is an incredible undertaking with very well written documentation. Thank you for making this library, I think there's a lot that the Ruby community can benefit from with it. Cheers!

I made an app to control my pedalboard via WebMIDI

https://github.com/rajangdavis/macrocosm_js

Was inspired by some existing editors so I made my own and extended it to create macros for sending sysex/PC messages to multiple devices.

I think this is pretty neat, my only feedback is that I'd like to see documentation on how to incorporate with an existing or new Next.js project.

I looked through the docs and did a couple of google searches and found nothing, but what’s the story with using toit for a DIY MIDI controller using the ESP32?

rajangdavis — Mon, 02 Jan 2023 15:41:57 +0000

To summarize my experience, state is hard, phones got introduced as a target, and browser code became fun to write.

Is the complexity artificially inflated? It depends on the app you want to make.

What’s the story surrounding cross platform MIDI support? I don’t expect it to be a priority but it’s something that I was looking into with Flutter/Dart, it would be killer to have.
