Blog about things you don’t understand yet

💥 Discover this insightful post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: Every post I publish represents at least two things I’ve learned: the thing that prompted me to write the post, and the thing I learned in the course of writing it. If I don’t learn anything new while I’m writing, it’s not interesting enough to publish. Typically I learn way more than two things. For instance, in my o3 geoguessr post, I started out with the idea that most AI prompts probably don’t work, and I ended up learning that newer OpenAI models have lost…

Introducing Bluesky Protocol Services – AT Protocol

🚀 Discover this insightful post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: Today we’re launching Bluesky Protocol Services: a new brand, and a new website, for the public infrastructure Bluesky operates on the AT Protocol network. Bluesky has always run more than the Bluesky app. We operate Jetstream instances, relays, and the Bluesky API endpoints built on atproto. But if you were a developer trying to build on that infrastructure, our docs didn’t always make it easy to tell what we run as a service or where to start. We’re fixing that today. Bluesky Protocol Services organizes…

how AI text watermarking works: a visual guide

how AI text watermarking works: a visual guide

💥 Read this insightful post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: ← declaude A gentle, visual walk through how a statistical mark hides inside generated text, and what erases it. From the folks at NOPE, as a companion to declaude. A watermark in plain text sounds impossible. Text has no pixels to hide data in, and no metadata survives copy-and-paste; every character is right there in front of you. Where could a mark possibly go? And yet the marks are real. Google has watermarked text from the Gemini app and web experience since 2024 (its API…

How Compaction Works in Pi

💥 Explore this trending post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: If you have ever had a long coding session in a coding agent like Pi, Claude Code, or Codex, you will have triggered a compaction. In this post we explain how compaction works and when Pi needs to compact. An LLM conversation Large language models (LLMs) have limited context windows. The context window is what the model can "see" while producing a response. The transformer architecture used by LLMs limits how much input they can process. The input for a coding agent session includes all…

How Gödel’s Proof Works | Quanta Magazine

💥 Discover this insightful post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: In 1931, the Austrian logician Kurt Gödel pulled off arguably one of the most stunning intellectual achievements in history. Mathematicians of the era sought a solid foundation for mathematics: a set of basic mathematical facts, or axioms, that was both consistent — never leading to contradictions — and complete, serving as the building blocks of all mathematical truths. But Gödel’s shocking incompleteness theorems, published when he was just 25, crushed that dream. He proved that any set of axioms you could posit as a possible…

Understanding is the new bottleneck

Understanding is the new bottleneck

🔥 Discover this awesome post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: Another example. I was migrating my personal website from one framework to another, and Claude wrote a script that did it. But it was very hard to review: I wasn't familiar with the new framework, and all I could say was “I guess that looks about right.” So I asked Claude to make me a video game — a command center where I do the port myself, step by step, watching the visible effects and the file tree evolve. It produced a UI where I…
