I made a small animation illustrating my geometric intuition for what happens inside a simple feedforward ReLU neural network. Hope this is illuminating for someone.

In the last years, I spent some of my scarce free time writing up what I had learnt starting and running two companies, zynamics and optimyze The article is still work-in-progress, but I thought it's best to publish it now and iterate in public:

The weirdest observation: I generated movies visualizing the polytope boundaries for ReLU networks using Muon and AdamW. Same experiment, same data, same random seed. The difference is the "crease pattern" that the optimizers produce.

Confession time: I use agentic coding all day, every day. It makes me much more productive. But I am also terrified of skill atrophy, I feel like I need to break out pen & paper to force myself to "weight-lift" mentally so I don't forget how to think. How do y'all handle this?

Thomas Dullien zu Anthropics Mythos: Software war nie auf perfekte Sicherheit ausgelegt - das rächt sich
Schwachstellen in Computern wurden lange hingenommen. Denn sie auszunutzen war technisch komplex und teuer. KIs ändern das nun. Damit zwingen sie uns, Altlasten schneller anzugehen.

famously referred to a similar dynamic as the Mitigator (illustrated by a cartoon alligator), who piles security mitigations on without regard for cost-benefit analysis, broader context, quantitative evidence etc. on the theory it "makes things harder"

Same code using twice as much CPU. Took about a year to get an answer out of GCE support, which was basically âunlucky with NUMA positioningâ. (Oh, and the hypervisor lies about NUMA)

I am observing up to 30% (!!!) wall-time fluctuations running the same code on the same data and the same VM type on GCE. That seems insane to me, in terms of noisy neighbor effects. What is the worst fluctuation you've seen on cloud machines?

It is the sovereign legal right of every country on the planet to repudiate their debt, and they can and do suffer essentially no consequences other than loss of access to credit markets for about 3-5 years. This is in fact so disastrous that countries prefer almost anything else to doing it!

Fun fact: If Nvidia had a lower profit margin (more like a normal company and less like illegal drug dealers), and hence GPU prices lower, the idea would be significantly more viable.

LLMs are reshaping software dev. I don't buy "the end of software dev": Project ambition will grow dramatically. Ancient Egyptians could build the Pyramids but not the Empire State Building. Pre-LLM software will be viewed like we view the Pyramids.

2/ Altho massive punitive damages jury award against NSO Group ($167m) got reduced by the court, as is expected in cases where it is so large (to 9x compensatory damages)... This is likely cold comfort to NSO since I think the injunction seriously dims value of NSO's spyware product.

Kinda wild to think the Berkshire's 350bn cash pile is likely in T-Bills, and that 350bn is almost 1% of the 37Tn in total US debt. Berkshire alone holds 1% of US debt.
