In a way, all math proofs already exist. Humans just have to determine what is worth looking for and uncover them. AI will help us do the latter. But we still have to do the former ourselves. It will still require sound mathematical knowled

Or, moreover, legal safety policies are essentially written by the companies that produce the product, by their own definition of safety, and pushed by their own lobbyists to codify into law, effectively giving them monopoly power. Safety i

It's useful to keep these anyway, as if you make a change that accidentally changes the type of some function, the error message makes it immediately obvious what you did. Otherwise it's hard to tell whether you messed up the func

Everywhere I've worked requires a DR drill per service, but I've never seen anything where the whole company shuts down a DC at once across all services. But probably we should. It's an immensely larger coordination problem,

Oh, I was measuring the sides in Euclidean length. In Manhattan length they're 2000 each, so area is 4 million.

The area of the circle in Manhattan distance comes out to 2 million, but pi * r^2 is 4 million. What am I doing wrong?

See Norton's Dome as an example of nondeterministic behavior in classical mechanics. No quantum or chaos etc required. https://en.m.wikipedia.org/wiki/Norton%27s_dome

Classical mechanics does have nondeterministic cases even without appeals to mathematical paradoxes. See https://en.m.wikipedia.org/wiki/Norton%27s_dome as the most well-known example.

I read that Brex moved away from Elixir to Kotlin. If Elixir was really that great then why would a company put such a big effort to ditch it? That killed off my interest in learning it, but maybe their reasons were invalid? Genuinely curio

Any way to reasonably estimate how long it would take to compile back then? The PDP-11 was 1.25 MHz, Would it be roughly 4000x slower than compiling a 13K-line C program on a modern CPU? Or are computer architectures so much different that

How do they calculate CO2 from logging? Hopefully they don't assume the entire tree ends up in the atmosphere. Or does it?

Don Syme makes a distinction between OOP and "object programming" various places on the internet. Object programming is quite natural in F#; possibly even moreso than in C#. And it's certainly not more verbose in F#. That&#x2

I felt the same, but once you get used to the syntax, it's much nicer for functional first coding. If you find yourself fighting the syntax a lot, you're probably using it in an imperative style that is not idiomatic in f# anyway.

Funny, I did exactly the opposite! I really enjoyed f#'s functional-style web framework Suave, but put it on top of services written in OO style, which all used immutable f# records and lists under the hood. It ended up being a lot eas

Similar to how a magnet works. A magnet can hold something forever, so seems like a violation of thermodynamics. But "holding" isn't work, it's just force. (Which is still kinda spooky, admittedly) Similarly, conducting

Isn't this just E(f(x)) != f(E(x))? The first part shows the expected value of the return function, which is positive (from the gambler's perspective). The second part uses f(E(x)): the gambling function applied to expected number

This isn't really edge. It's multi-region. It's a great intro to multi-region considerations, but it's not edge. Edge implies putting your stuff in a CDN-sized datacenter that has only a subset of the full regional servi

The article acts like this was an atomic switch, but certainly it was rolled out service by service over more than a year, in which case the comparison is grain of salt.

Pictures are worth a thousand words. Writing is reasonably easy and it's hard to get much better than you already are. If I had it to do over again, I'd spend a lot of time learning drawing and diagramming tools. They still intimi

I thought the principle of the excluded middle was the ultimate source of that paradox, not set theory itself?

My understanding was that you just had to get rid of the law of the excluded middle. Then things like Russell's Paradox can be stated, but evaluate to neither true nor false, and be fine. Is that not correct?

Is set theory more useful than category theory for dynamic types? Seems like set theory is less constrained, like a set can be part of itself by nature, whereas category theory generally doesn't allow mixing containers and elements lik
