Not sure that’s quite equivalent; Megacorp scraping the entire internet vs individuals sharing knowledge on a platform are a completely different scale.

What’s more, if you need to compute F_n, you can do the matrix power by exponentiation by squaring. It can speed up the calculation quite a bit.

Vast sprawling suburban wastelands with no services is not the solution. Just build houses is easily said but it’s not necessarily where people want to live.

Switching to EV is an infrastructure problem just like public transport. Guess it’s doomed because it’s not driven by profit.

I don’t want cities to build stupid EV charging crap everywhere. They could invest that in public transport instead. EVs have all the same social problems as cars.

Use a programming that is decoupled from stateful manipulations and control flow? Programming does not need to involve itself with the hardware, that’s just a tool for evaluation. …

The whole point of Algebraic Geometry is to describe geometry using algebra. It’s is a very deep, successful and important subject in modern mathematics. I wouldn’t say it needs to…

Why does it have to be so siloed? What if I want documents with a slight bit of inactivity? Why must I go through two different protocols? What if I want to read a paper next to th…

I disagree on it being the OS maintainers job, for the reason of duplication of effort. Packaging every single package or library individually for every distro is a colossal waste …

Yes I would say most of physics we currently can make predictions with are just effective models that are only applicable at some certain scale. Certainly there may be some underly…

Basically approximating a solution, and then finding an equation from some data. Nothing wrong with writing down an approximation to some problem. An approximation can be very usef…

For b) most people do not read a paper linearly, you look at maybe the intro, skim around a bit, and then maybe go to an appropriate section. If you are really invested then maybe …

Dynamic typing failures come up in math too. People love to ignore precisely where functions are defined, and then try to dynamically extend it elsewhere and are surprised when it …

Basically the article is just lazy evaluation like in Haskell working with infinite lists. Numbers like Pi, e, sqrt(2) are the programs that generate them. However we use syntactic…

Not very hard to achieve similar results with LaTeX, just make liberal use of mathrm, custom commands and spacing, eg \mathrm{det}(A) shorten to \det{A}

Does someone have an example where the ability to “differentiate” a program gets you something interesting? I understand perfectly what it means for a neural network, but how about…
