💥 Explore this trending post from Hacker News 📖 📂 Category: 💡 Here’s what you’ll learn: If you asked most people to name a defining feature of AI-generated writing, they’d probably say the em-dash — like this. Language models use em-dashes so much that real humans who like em-dashes have stopped using them out of fear of being confused with AI. It’s also surprisingly hard to prompt models to avoid em-dashes: take this thread from the OpenAI forums where users share their unsuccessful attempts. Given all that, it’s kind of weird that we don’t really know why language models use…
🚀 Explore this trending post from Hacker News 📖 📂 Category: ✅ Key idea: I'm impressed with the level of compatibility of the new memory-safe C/C++ compiler Fil-C (filcc, fil++). Many libraries and applications that I've tried work under Fil-C without changes, and the exceptions haven't been hard to get working. I've started accumulating miscellaneous notes on this page regarding usage of Fil-C. My selfish objective here is to protect various machines that I manage by switching them over to code compiled with Fil-C, but maybe you'll find something useful here too. Timings below are from a mini-PC named phoenix…

The students had to implement the forward and the backward pass of each layer in raw numpy. Inevitably, some students complained on the class message boards:“Why do we have to write the backward pass when frameworks in the real world, such as TensorFlow, compute them for you automatically?”This is seemingly a perfectly sensible appeal - if you’re…

🚀 Explore this trending post from Hacker News 📖 📂 Category: 💡 Main takeaway: I’ve had a few conversations about async code recently (and not so recently) and seen some code that seems to make wrong assumptions about async, so I figured out it was time to have a serious chat about async, what it’s for, what it guarantees and what it doesn’t. Most of the code in this entry will be written with Python syntax (and often Python libraries), but with a few minor exceptions, we’ll be discussing concepts that are valid across languages. We all know about performance,…
💥 Read this trending post from Hacker News 📖 📂 Category: 📌 Main takeaway: High-performance lockless spsc/mpsc/mpmc channels. It supports async contexts, and communication between async and blocking contexts. The low level is based on crossbeam-queue. For the concept, please refer to the wiki. V1.0: Released in 2022.12 and used in production. V2.0: Released in 2025.6. Refactored the codebase and API by removing generic types from the ChannelShared type, which made it easier to code with. v2.1: Released in 2025.9. Removed the dependency on crossbeam-channel and implemented with a modified version of crossbeam-queue, which brings performance improvements for both async…

In 2000, he visited my AI company Webmind Inc. in New York City, where we were explicitly trying to build AGI alongside various commercial applications. His mission? To convince us to maybe stop. Or, failing that, to get us thinking really hard about AGI safety and how to make the AGI good for everyone.While he…

Not long ago, ordering a pizza meant visiting a website, clicking through menus, and entering your payment details. Soon, you might just ask your phone to order a pizza that matches your preferences. A program on your device or on a remote server, which we call an AI agent, would visit the website and orchestrate the necessary steps on your behalf.Of course, agents can do much more than order pizza. Soon we might use them to buy…
