Enzo's dad 🇬🇷 in LA 🌴
Docs will be replaced by well-crafted custom GPTs by this time next year. About time!

Hey @elixir-lang.org folks: what are some of the best system prompts or cursor rules you’re using on the daily?
March 11, 2025 at 12:34 PM
After 2 years in production, I sadly cannot recommend Absinthe if you’re building graphql APIs. Unergonomic, plus you’re missing out from all the tooling in the JS space. I’d still use elixir for many cases, eg have the resolvers call into an elixir service, with minimal logic in the BFF.

Claude 3.7 is 🔥
But I still love how fast Gemini Flash is.
An o3 is a workhorse.

Isn’t it great we have such epic choices?

Elixir I love you, but you’re bringing me down. New chapter.

Gemini 2.0 Flash is really good (and fast!). It’s now my current default in Cursor.

We have been overwhelmingly impressed by getunblocked.com. It essentially renders code documentation irrelevant. Our latest hires got onboarded insanely easily to our code base.

everything is fine

Oban is too good of a tool to be limited to be used only from elixir apps. I wonder what would be the lift for being able to use it as a lightweight replacement for Temporal (which is polyglot)

The more I use GenAI coding tools, the more I am convinced keeping to "traditional" software engineering practices is what works most productive here. As in 10x more productive. E.g.

- Small changes
- Test that the change works before moving on
- (unit) tests wherever you can

I’m not sad that stackoverflow is dying because of LLMs. It walked so we could run.

Remember onavo? Good, old American spyware.

Not all fast software is great but all great software is fast

Zero discussion about Explode on my feed. If I weren’t on Twitter, I would have missed the boldest app launch of the year. Who do I need to follow?

The explode app and launch is a masterclass. Nikita has done it again.

I have been watching the devastation in LA from Greece and I cannot start to comprehend the vastness of destruction

“A moment on your lips, the rest of your life on your hips”. Applies for ice cream but also for LLM-generated code. Code is a liability you must live with and support for months and years after it’s written. Just because you can commit 1000s LoC in a day, you probably shouldn’t.

What a devastating week for LA.

I am so itching to play with Zero. Knowing Aaron, this is probably gonna be epic local-first infra. What to build?! zero.rocicorp.dev/docs/introdu...

Woke up to crazy photos and videos from back in LA. Massive fire, our house already used for friends being evacuated.

The unfair advantage of building with mainstream tech like React is that the LLMs have a ton more training data on them. So you can build + iterate faster. Languages don't matter, products do.

Two marathons. Two solo trips with my boy to Greece. Second app launched with the team. Pretty fucking good year.

If you take all the time it takes to configure nvim, calculate how much you make as a developer and boom! You have enough money to buy a new MBP that can run cursor that works epic ootb and go on with your life.
