This little button right here will make operator the killer app for AI

Come on in to K-Scale Labs AI day and see their two new humanoid robots. Founder Benjamin Bolte gives us a tour. He started his career on Tesla’s AI team. Exclusive on X. Recorded on Apple Vision Pro. Will load a second video on replies shortly. I have been to hundreds of

Const_missing and AI: A Ruby Metaprogramming Experiment Intrigued by the idea of AI-powered metaprogramming? In my latest "Works on My Machine" video (ubstack link in bio!), I delve into a wild Ruby experiment: using const_missing and caller_locations to get an LLM to generate

My name is Prasanna, who previously founded Rippling (worth $10B); I'm going through a divorce. I'm now on the run from the Chennai police hiding outside of Tamil Nadu. This is my story.

Just re-discovered these Programming Principles I wrote down in a note called "Mission Statement" years ago. I still think I stand by them 100%?

As much as I like algorithms & data structures, it's not really scratching the itch for me anymore. I've been doing NeetCode fulltime for 2+ years now and I've been loving it. But I don't get to work on technical things as much, and it's been really weighing on me. A lot of

We've switched to using CodeCrafters for our interviews. Zero restrictions on using AI tools. Copilot, Claude, ChatGPT, Cursor - everything's fair game. 90% of candidates still don't make it through 4 stages of the Git challenge in under 3 hours

What it looks/feels like to "sculpt" with math+logic

Ask gpt-4o to generate an image with a clock and it ALWAYS uses 10:10 as the time, even if you ask for a different time in your prompt. Ask it again to change the time and it goes bonkers:

Had a great time sharing the Clerky story, from how we got started to how we’ve stayed focused on the details that matter to high-growth startups. forbes.com/sites/allbusin…

This repository is a compilation of well-written, step-by-step guides for re-creating our favorite technologies from scratch.

Huge props to Build your own X for creating these challenges! There is nothing else like this out there, and their attention to detail even in very little things was exemplary – they even created a cool binary data formats visualizer for these challenges! app.codecrafters.io/courses/kafka

One project I would highly recommend, if you haven't done it already, is to build an HTTP web server from scratch. The server should serve static files, and as an extension, should allow you to define and serve APIs, like Flask. Use your favourite programming language, but build

Nice! Rails now has temporal-like functionality out of the box

Tried a bunch but this agentic coding thing just doesn’t click for me. Might work if it was 10x faster. At the moment it’s too slow — context switching kills flow

I want to get away from terms that make our craft more science than art. AI enables anyone to make things usable: our job is to make them unforgetable (2/3)

Hello Gemini 2.5 Flash-Lite! So fast, it codes *each screen* on the fly (Neural OS concept 👇). The frontier isn't always about large models and beating benchmarks. In this case, a super fast & good model can unlock drastic use cases. Read more: blog.google/products/gemin…

Imagine how many cache misses we could avoid if people just used tree_sha instead of commit_sha

Those who stuck to monoliths and avoided the microservices fad are having the time of their life right now — this is LLM usage heaven

been procrastinating on this one for a bit but new nan.fyi is now live :)
