Hearing from a lot of good founders that AI tools are writing most of their code now. Software engineers orchestrate the AI. They are also finding it extremely hard to hire because most experienced engineers have their heads in the sand and refuse to learn the latest tools.


I'm so addicted to Claude Code like @kieranklaassen :) so Sonnet 4.5 will be my daily driver. Using it since 20 min and it feels much snappier

BREAKING: Anthropic just dropped Claude Sonnet 4.5! We've been testing it for a few days @every and here's what we found: - It's smarter and faster than Opus: It solved a nasty bug for @kieranklaassen than Opus 4.1 was continually failing at. And it feels twice as fast. - It's…

AI will blur the lines between many functions over time because you can now begin to do things either higher or lower in the stack, or expand to other adjacent functions. A very obvious area is that PMs should almost always be showing up with functional prototypes.

We are adding a coding section to all of our Product Managers interviews at @Shopify. We'll start with APM interviews. We expect candidates to build a prototype of the product they suggested in the case interview. There is no excuse for PMs not building prototypes.



No more separate bash instance

Claude Code can now handle long-running tasks in the background. Start your dev server, run tests, or build your project without blocking your workflow



I love the way people at Every do vibe checks. Everything in one place without marketing hype

Vibe Check: GPT-5 is here—and it’s the best model most people will have ever used. We spent weeks testing it: vibe coding, debugging, Diplomacy, writing essays. Our full Vibe Check is here ↓

I attended a vibe coding hackathon recently and used the chance to build a web app (with auth, payments, deploy, etc.). I tinker but I am not a web dev by background, so besides the app, I was very interested in what it's like to vibe code a full web app today. As such, I wrote…
