I've heard of seL4, but I don't think it gets used much in the software industry. Not getting used kind of defeats the point of it, unless we need another 20 years for the formal methods people to produce an OS kernel people will

Maybe, but I'm not totally convinced: If an AI understands intentions, then it can carry out our intentions without us doing any traditional programming, specified using only plain English, especially in a safety-critical situation w

With LLMs revolutionising programming, maybe there's not much room left for using formal methods. Postmortem: The problem that needed solving: Computer programs make mistakes because they're too literal and they don't underst

How does throwing more money at the problem help? How you spend it matters. Otherwise you're just setting it on fire.

Leap seconds and UTC vs UT1? Even in your use case, this would matter. But yeah, I take your point.

> it's a simple integer that monotonically increases It isn't. See leap seconds . Using a string would allow you to distinguish UTC from UT1. Only UT1 is monotonic.

I think Bret Devereaux's article on why the Industrial Revolution started in Britain and not elsewhere is quite interesting ([1]). The Industrial Revolution happened not only because of advances in politics and engineering, but also be

No, it doesn't mean he's right. The "normal forms" could merely be suggestions for a database designer, not a technical limitation enforced by the software itself. No one has provided convincing evidence that Codd inte

While I think you're being genuine, remember that si vis pacem para bellum : "if you want peace, prepare for war". A blanket antimilitary view is very dangerous. A company should only be ostracised if it's helping carry

I have a theory that Haskell's main applications are in teaching and academic research - both concerning theoretical computer science. It's not a practical engineering language.

Expressing physics with more rigorous mathematical or computational formalism might be good: For instance, a force is a triple (sending object, receiving object, force vector). Newton's third law says that whenever there is a force (S,

I've addressed this point above. Remember that Australia and the UK do have some obligations to their allies. I'm actually opposed to extradition, but in favour of a trial and potential punishment outside the US.

Yeah, I guess he's not a US citizen, but an Australian citizen based in the UK. That said, Australia and the UK have clear obligations to their allies. I think maybe sending him to a neutral territory might result in a fairer trial. Th

Leaking national secrets needs to be punished to deter people from doing it. You can do it, but you must also be willing to defend your actions in a court. This seems necessary, as an organisation can't operate without keeping some sec

When you say SVM, do you mean any classifier that finds a separating hyperplane, like a no-hidden-layer "perceptron" or Naive Bayes, instead of one which finds the maximum margin hyperplane? Or is finding the maximum margin import

That's a more controversial and interesting take than "an informal structure in an organisation is not necessarily better than a formal one".

That would suggest that 1-Hidden-Layer neural nets would work fine, since they are also universal function approximators. But no -- when people talk about "deep learning", the word "deep" refers to having lots of hidden

I've thought about this now, and I think that: - the scientists people know about are generally older - older people are often thought of as wiser, or may indeed be so - when a famous scientist - who is already likely to be older, and

I've heard this before, but why would it be true? Serious question. I've seen Chomsky argue that LLMs can't regurgitate his linguistical theories - but ChatGPT can! I've seen Penrose argue that AI is impossible, and yet

Is the next generation of GCs going to use Reinforcement Learning and Machine Learning? The problem with a lot GC is that there's a currently unavoidable tradeoff between memory usage, latency and throughput.

You should ask it to show its working. The problem is that it uses a fixed amount of thinking for each character - and it writes left to right - while long multiplication is computed right to left. Past a certain number of digits, the amoun

You probably used GPT-3.5. That said, I didn't manage to get GPT-4 to calculate 36,330 * 26,951 correctly. I suggested casting out 9s, casting out 11s, doing long multiplication, reversing the digits - nothing. I have a theory that it
