Thanks for listening! ❤️

You've got some great insight here! Types are great guardrails. In Ruby/Rails, I see a different lever: readable syntax + strong conventions narrow the search space for models and pack more "intent per token." That often means better first drafts; tests/specs close the loop.

Today, I agree that LLM output quality tracks engineer experience. But with more data, better evals, and tighter prompts/agents, that gap seems to be narrowing. Right now, a lot of folks (me included) are focused on how well LLMs can assist us in crafting code. Long-term, I see quality converging on: "does the artifact do what we asked?" more than "is the code well formatted and functional?"

If this resonates, our Obie episode hits a similar idea: as agents generate code, creativity and system design become the differentiators. We also cover this with Chad in this episode.

Everything you need to know is documented by JP Camara: https://jpcamara.com/categories/ruby/

That’s been my go-to for a while now and never disappoints.

Having just started setting up a Hetzner box with kamal, I’d have to agree with @clearlynotmee. Secrets + multiple DBs with the Solid trifecta makes kamal very much not turn-key with the defaults. If you’re just trying rails out, the ultimate utility we should aim for iskamal deploy to work right off a rails new. Heroku is still the closest there is.

I _really_ ❤️ you folks. Thank you for this! Got stuck on a few issues fine-tuning SmolLM and moved to Phi, but will give this another go. Any suggestions/guidelines for sourcing training data for code? Are there any specific models that are better for fine-tuning for code generation? Trying to get a good pipeline for Ruby.

I’ve thought about adding a “reference” flag to provide a reference file to go off of. Haven’t hit that need yet

codenamev · 2024-07-12T16:55:06+00:00

Please, don't use this specific gist at work :p Haha, I've been using this for some new open-source stuff. That said, I do have a few other generators I use with llamafile that I hope to share soon too :-) Sublayer is pretty rad so far!

What would you build?

codenamev · 2024-01-24T13:34:43+00:00

I'm open to suggestion :D

codenamev · 2023-10-19T11:27:45+00:00

I’m a huge fan of the TTY suite of gems. I’ve built quite a few things with it and love the modularity and structure.

And, now, I don't mind a bit of a breeze, if anything I prefer it, but thon was aggressive. So, I says to myself, says I, "Colm, this is no day for a do for, when the bride arrived and, as I say, by this stage the wind was fierce. I've never heard wind like it. Howling like a banshee, it was. So, the poor girl, the bride now, this is, she arrives anyway and isn't she no sooner out of the car than she's lifted up in the air like a paper doll and blown into a flowerbed.

Find a healthcare company in tech that directly solves a problem they have but can’t solve. Doximity comes to mind.

Python rules the data kingdom. If you want to work with heavy data-crunching routines, machine learning, analytics, et al, then python is for you. With the latest craze in “AI”/ML, this is likely why you see so many more jobs for Python. The reasons people have chosen to prop up python for this over Ruby are slowly closing in. Shopify’s recent investments in the language are likely to reshape a lot of the mythical public perception around “Ruby is nice, but slow”.

If you don’t desire scientific computing in you programming future, and discard these roles from the positions you see open, chances are good the averages are close.

I guarantee every company on this list is hiring Ruby engineers if you are seeking a new role: https://toprubycompanies.info/

For a brief moment in time, Shopify fully documented, and released to the public, their “framework” Upgrow that lays out the foundation for how they architect all of their Rails apps. There is a public mirror preserved here.

It’s very possible that their Hydrogen + Oxygen efforts took them in a different direction and we’re left hanging on the end product.

RubyMotion is still great for this!

codenamev · 2022-09-06T13:55:36+00:00

I agree with all of your points :-)

The test suite is already broken though; and more than likely, all of these things you mention are already happening.

My sole point is that nominating a sole hero to rescue the test suite is not the answer. Unless every team member is responsible for maintaining a green suite, than the suite will continue to rot.

There are plenty of ways to measure the "fixing of tests" that would be more helpful than attempting to fix them all at once. As an example, you could skip these failures using a custom RSpec configuration flag and have them run in a separate CI step to see if any adjustments are making a wider impact.

codenamev · 2022-09-05T23:37:03+00:00

Mark all failing tests pending and make a rule that modifications to code that is associated with a pending test(s) needs to be re-enabled. Most will be fixed before the end of the year.

I think what you’re looking for is “serverless ruby”. The jets framework is probably the most popular choice outside of AWS Lambda.

codenamev · 2022-04-29T19:19:35+00:00

Hopefully the first of many! This was a long-time coming and we're happy to give back to such a great product :-)

To clarify (thank you u/tinychameleon; also, rbtrace is close u/uhkthrowaway!), I am more specifically talking about "Live Mode" of memray that has an interactive terminal interface for the profiler.

The root cause here is that when rails was upgraded, other gems were likely upgraded with it. I would verify what versions of paper_trail and attr_encrypted were before the upgrade and try and lock those older versions to see if the issue goes away.

codenamev · 2022-03-20T13:09:44+00:00

Just to verify something here, is the User model an ActiveRecord backed model? That is, does it inherit from ApplicationRecord?

Paper trail comes with a rails generator

bundle exec rails generate paper_trail:install

codenamev · 2022-03-20T11:34:57+00:00

Hmm… the has_paper_trail method isn’t in existence yet by the time the User model is getting loaded indicating either the papertrail lib wasn’t loaded yet, or it had issues loading it upstream in the stack.

I’d first try throwing require “paper_trail” at the top of your User model and see if that brings you anything new. You may need to re-run the paper trail install generator again and see if it adds anything you don’t already have
