Rust in the Linux kernel coexists with C. I wrote an article on a new Rust abstraction I created to support iterfacing with C linked lists, enjoy :) joelfernandes.org/blog/2026-02-0…

Every single one of the 11 Meta superintelligence hires is an immigrant who did their undergrad abroad. 7 China, 1 India, 1 Australia, 1 UK, 1 South Africa. 8 are PhD or PhD dropouts in the US. Immigration is key to US AI innovation.

Elon's week be like...
I am wondering why #LLM coding benchmarks like #Aider Polyglot reveal the coding problems they are testing on. Doesn’t that give the models an opportunity to be trained on the problems in advance, thus defeating the scoring? aider.chat/2024/12/21/pol… github.com/Aider-AI/polyg…

It is my honor to be designated as Godfather of the 2025 Kernel Recipes. The conference organizers asked me to help increase the speaking skills of the presenters. This blog series is a first step in that direction: people.kernel.org/paulmck/kernel…
This is safety beyond the usual unsafe memory access protections and is more than welcomed and fascinating! Especially since issues are caught much earlier at compile time! 2/
I’m fascinated that rust lang couples synchronization primitive types with structures they protect thus allowing for common programming mistakes to be caught at compile time! (ex, dropping a lock too early or holding wrong lock like rwlock in read mode during mutations). 1/
@paulmckrcu You do like to put a lot of guardrails in code you write, for good measure! ;-)

Here's our statement on the results of the 2024 presidential election:
AI video gen is heating up. This is going to disrupt commercial video advertising AFAICT. Multiple ready to use tools now exist: Kling ai, Flair ai, runway ML etc
Welcome to the new age of AI advertising. We generated a commercial for @elonmusk's Optimus Bot with Flair AI. Try out our Optimus model and animation workflow below. 👇
lwn.net/Articles/99509… OpenSSL adds a number of new encryption algorithms, support for "“directly fetched composite signature algorithms such as RSA-SHA2-256”"
@derkling Further I think if you look deeper into it, Trump has been a strong Israeli supporter. So that should be another reason to not elect him if that was your reason (other than him being a convicted felon and racist)
@derkling The issue you are describing has nothing much to do with my initial tweet though. I’m talking about presidential election. Funding for Israel etc is approved by congress. You are talking about the US position on this issue which the election doesn’t have much direct bearing on.

The ourouborous has begun. Wikipedia is an important source of training data for AIs. At least 5% of new Wikipedia articles in August were AI generated (To be clear, this does not mean that AI will fail as it trains on its own data, synthetic data is already a part of training)
Half the country is voting for a climate denying criminal fascist. This is absolutely insane #Harris
@derkling Also, voting for lesser evil (if it was even that) is still progress to ensure evil doesn’t win ;-D
