Notes by djb on using Fil-C (2025)

πŸš€ Explore this trending post from Hacker News πŸ“– πŸ“‚ Category: βœ… 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…

Yes you should understand backprop | by Andrej Karpathy

Yes you should understand backprop | by Andrej Karpathy

πŸš€ Check out this trending post from Hacker News πŸ“– πŸ“‚ Category: βœ… Here’s what you’ll learn: When we offered CS231n (Deep Learning class) at Stanford, we intentionally designed the programming assignments to include explicit calculations involved in backpropagation on the lowest level. 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:β€œWhy 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…

(Quite) A Few Words About Async

(Quite) A Few Words About Async

πŸš€ Explore this trending post from Hacker News πŸ“– πŸ“‚ Category: πŸ’‘ 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,…

frostyplanet/crossfire-rs: A lockless mpmc/mpsc to support async base on crossbeam

frostyplanet/crossfire-rs: A lockless mpmc/mpsc to support async base on crossbeam

πŸ’₯ Read this trending post from Hacker News πŸ“– πŸ“‚ Category: πŸ“Œ 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…

Why β€œEveryone Dies” Gets AGI All Wrong

πŸš€ Explore this must-read post from Hacker News πŸ“– πŸ“‚ Category: βœ… Key idea: Being: A reaction to Eliezer Yudkowsky and Nate Soares’s book β€œIf anybody builds it everyone dies” which is getting a bit of media attentionI’ve known Eliezer Yudkowsky since the late 1990s. 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…

rate-limiting bots and agents without compromising privacy

πŸš€ Discover this insightful post from Hacker News πŸ“– πŸ“‚ Category: πŸ’‘ Key idea: The way we interact with the Internet is changing. 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…

Info – Sailfish OS

πŸ’₯ Check out this insightful post from Hacker News πŸ“– πŸ“‚ Category: πŸ’‘ Key idea: Sailfish OS’s heritage lies in Nokia times, especially in the MeeGo operating system. Prior to 2011 Nokia and Intel had a vision of an open mobile operating system. Together they invested around 1 billion USD to the project and created an open source based operating system called MeeGo, which was used as a basis for several devices, such as the iconic Nokia N9. Although the Nokia N9 became the beacon of open source operating systems, Nokia decided to end the project and chose instead to…
