A lot of that is compute commitments and NVIDIA has a 80% margin

they were definitely totalitarian, slightly different mix of ideology. Fascist is a fairly good description here, it describes close collaboration of government with corporations to advance national goals. US had somewhat fascist tendencies for a long time now.

I don’t get that, the use of these books was instrumental and necessary for the success of the training run. The expected value of these training runs is high as the build out of 100 billion+ infrastructure demonstrates, so the book publishers should at a minimum be paid a licensing fee, a small fraction of every inference run revenue or whatever they decide. The fact that authors and publishers didn’t get any say under what conditions their intellectual property can be used is pretty outrageous.

In fact 5g and all previous standards have a provision for lawful intercept. So your domestic intelligence service and police can always turn it into a listening device.

I guess we will find out in 20+ years once the next electron positron collider at CERN has been build

Curious how this relates to what lean4 is doing, I guess in lean's case some of the data structures are special cased (Array) and there is no easy way to implement such data structures yourself

At some point we will be so tired of distinguishing between AI generated content and human content that we will stop using the Internet and it will be left to bots.

It took cerebras less than a billion to get to where they are now, CPUs are not that hard. You would probably be able to reverse engineer them for ~100 million

I mean in a normal math curriculum you would define only the multiplicative inverse and then there is a separate way to define fraction, if you start out with certain rings. It is kind of surprising to me that they did a lazy definition of division.

New comment by orbifold in "JOPA: Java compiler in C++, Jikes modernized to Java 6 with Claude"

orbifold — Wed, 26 Nov 2025 17:50:49 +0000

One other thing I've observed is that Claude fares much better in a well engineered pre-existing codebase. It adopts to most of the style and has plenty of "positive" examples to follow. It also benefits from the existing test infrastructure. It will still tend to go in infinite loops or introduce bugs and then oscillate between them, but I've found it to be scarily efficient at implement medium sized features in complicated codebases.

New comment by orbifold in "US declines to join more than 70 countries in signing UN cybercrime treaty"

orbifold — Sat, 01 Nov 2025 20:36:54 +0000

A relative of mine worked for the UN and interfaced with the UN after they left for a non-profit. Anyone that knows anything about them and also just simply observing what and how they are doing things should have no doubt that it is filled with people that got there by using their connections. And you absolutely constantly run into people that have no business being there other than through nepotism. Btw. I am sure that US staff is less likely to be a total nepo baby, but because the UN "has" to hire from all over the world, most roles are not filled like that.

It will all make sense once you realize who works at the UN, basically nepo babies of all colors and variety, including second cousins of Saudi royalty etc.

what is striking to me is how far reasoning by analogy and generalization can get you. some of the deepest theorems are about relating disparate things by analogy.

It would be great if we got "kernel independent" Nvidia drivers. I have some experience with bare-metal development and it really seems like most of what an operating system provides could be provided in a much better way as a set of libraries that make specific pieces of hardware work, plus a very good "build" system.

orbifold — Wed, 01 Oct 2025 21:17:48 +0000

This is a terrible idea and direction but it will not stop people from pursuing it and as soon as they have a critical mass of people reviewing each other it will go on for quite a while. Transformers for time series is one of those things that seems to make sense but not really.
