Working with LLMs means reviewing way more diffs than before.
I discovered delta a while back and this was such a huge improvement to working in a terminal and having amazing syntax highlighting for diffs

New blog post: When ActiveRecord and Arel aren't cutting it, sometimes raw #SQL is all you need. I built AppQuery to make that experience better — with CTE inspection, ERB templating, and proper type casting.

Ruby isn't dying, it is already dead. So is every other language. Rejoice, you have been liberated! You no longer write Ruby for The Man, but yourself! Reclaim the means of production as the means of amusement! Ruby was created to make you happy, not the machine. Wrest back your joy!

Currently in ActiveJob, `wait` in `retry_on` accepts a proc, but it is only handed the execution count. I think access to the error can also be useful when calculating the next wait time. If you agree, give it a like! github.com/rails/rails/...

Seems like Ruby is pretty well positioned as a language that is token-efficient when used with LLMs.

Developer anxiety is actually a quality control mechanism. It makes us check edge cases and side effects.
LLMs aren't dangerous because they're wrong, but because they're fearless. They write terrifying code with zero hesitation.
Beware of what you approve. You are the only guardrail left.

I keep thinking about tests and types when generating code with LLMs.
Both matter, but they provide different kinds of confidence about code correctness.

I enjoyed this discussion with Pablo and Stan and I was, of course, super optimistic about #Ruby future and what it has to offer.
🚨 New Episode Alert 🚨
I was extremely privileged to be joined by Stan and @lucianghinda.com to discuss #Ruby (and a bit of Rails)
Why does ruby feels so elegant?
Can a programing language hold beauty?
Why did they decide to use or not use Ruby?
All that and more here: buff.ly/IpPalrj

Here's a script to demonstrate the first problem.

80-90% of N+1s I see in the wild are because an ActiveRecord models' instance method is causing an un-preloadable query.
Solutions include: manage data at the controller level instead, use scopes!
