I was reflecting on my usage of AI and realized that a well-written spec is the best prompt you can use.

I wrote about it in my blog. Check it out

@marclou @DataFast_ I'm about to do that with https://t.co/LcHGyN13b9

I implemented the web version in Elixir/LiveView and was trying to decide between Flutter and React Native.
Did you consider anything different? I definitely don't want to go with native.

Aos poucos, Elixir BH se torna uma comunidade forte em que trocamos experiências de alto nível.

#Elixir friends. I'm sharing a few words about smooth UI rendering and how Phoenix Pub/Sub is an amazing tool for building smart UIs.

I used it when developing https://t.co/LcHGyN1B0H, and I don't regret it!

Check out my post!

I'm Boris and I created Claude Code. Lots of people have asked how I use Claude Code, so I wanted to show off my setup a bit.

My setup might be surprisingly vanilla! Claude Code works great out of the box, so I personally don't customize it much. There is no one correct way to use Claude Code: we intentionally build it in a way that you can use it, customize it, and hack it however you like. Each person on the Claude Code team uses it very differently.

So, here goes.

Really interesting read!!

Cloudflare's postmortem about November 18's outage. It reflects how Distributed Systems work at scale and how hard it is when things go wrong 😀

Kudos to the Cloudfare engineers. Thanks for sharing this!

@anshagrawal1709 @posthog Wow. I haven't had issues so far. I'm starting to use funnels and more advanced tools, so let's see how it goes.
