Neural Networks Are Already CleanA working hypothesis about neurons, generalization, and the ecology of circuits
Nick Cammarata of Goodfire argues neural networks are already 'clean': polysemanticity and messy circuits may be less fundamental than assumed, and studying neurons and circuit ecology points toward more interpretable structure than the superposition story alone suggests.

Remote Attestation Should Not Be Tolerated
lumi argues that remote attestation—hardware proving software identity to a remote party—is harmful: it enables remote control over what users may run, undermines general-purpose computing, and should be objected to rather than normalized.

Frontier Pre-training at Microsoft AI
Microsoft AI details pre-training MAI-Base-2, a 2.8-trillion-parameter MoE foundation model (80B active) trained on 16k GB200 GPUs over 38 days, which it says beats the open-weight models it tested on held-out evaluations at 4-12x better pre-training FLOPs efficiency, covering scaling ladders with source scaling, hyperparameter scaling laws, MoE and Muon optimizations, activation gradient clipping and native vision data.

Using Artificial Intelligence to reverse engineer hardware
Christian F.K. Schaller describes using Claude Code with a Windows VM capturing USB traffic to write a working Linux SANE driver for his Plustek 8200i film scanner within hours, then reusing the setup to patch the kernel and libcamera for his laptop's MIPI camera, and releasing hw-harness, a generic toolkit to help AI agents reverse engineer undocumented hardware.

Mistral AI co-founder and CEO Arthur Mensch argues it would be a fundamental mistake for Europe to leave frontier AI models to the US and China. Pointing to the €260B+ Europe pays yearly to American cloud and software providers, he says whoever controls a model sets the terms, that open models only partly help, and that frontier AI is now a matter of security and science.

What was a Token Ring network?
Dave Farquhar explains Token Ring, the IBM networking technology announced on October 15, 1985 that competed with Ethernet through the 1980s and 1990s. He covers why Ethernet won, how to tell Token Ring cards from Ethernet ones today by connectors, speed markings and brand, whether the old hardware is worth using, and why anyone chose it.

I Know Why the Mathematicians WeepOn technological grief
Derek Thompson talks with Cornell mathematician Steven Strogatz about why OpenAI's flood of AI-generated proofs has left mathematicians grieving, arguing that science is both a craft and a conversation between minds, and that machines producing knowledge without human understanding threaten the social half of science that people will need to protect.
