It's not even about features. Calculators are mostly useful for napkin math - if I can't afford an error, I'll take some full-fledged math software/package and write a program that will be debuggable, testable, and have version control.

But for some reason the authors of calculator apps never optimize them for the number of keypresses, unlike Casio/TI/HP. It's a lost art. Even a simple operator repetition is a completely alien concept for new apps. Even the devs of the apps that are supposed to be snappy, like speedcrunch, seem to completely misunderstand the niche of a calculator, are they not using it themselves? Calculator is neither a CAS nor a REPL.

For Android in particular, I've only found two non-emulated calculators worth using for that, HiPER Calc and 10BA by Segitiga.Pro. And I'm not sure I can trust the correctness.

I'm the developer of an Android calculator, called Algeo [1] and I wonder which part of it that makes it feel like slow/not snappy? I'm trying to constantly improve it, though UX is a hard problem.

> the Python ecosystem is often far superior to both

What would you say does the Python ecosystem have that the others are missing? The obvious thing is pytorch/tensorflow/.... I can't think of much else though.

Pytorch and tensorflow is pretty big. It implies all state of the art research code is not written in Julia, so it is a non-starter for any neural network based project.

Honestly I don't understand the pessimistic view here. I think every release since Microsoft started funding python has increased high single digit best case performance.

Rather than focussing on the raw number compare to python 3.5 or so. It's still getting significantly faster.

If they keep doing this steady pace they are slowly saving the planet!

Because it only increases high single digit each release. If they keep up the 10% improvement for the next 10 release, we will reach a speedup of around 2.5 times. That's very small, considering how Python is like 10-20 times slower than JS (not even talking about C or Java like speeds).

I always wondered where the integral sign was coming from. This gives a very simple explanation: it's just the letter 's', the shorthand for sum!

This rings so true with me. I have a side project [1] that I try to promote and it always feels hard. Where do I start? Should I post comments in random subreddits? Should I write blog posts that may nobody read in the end? Start doing ads? I think having the multiple options kinda freezes me and it is so hard to start doing something.

Congrats! It's about the same I make with Android with my app (a graphing calculator) [1]. Everyone says on Android you can earn less, I'm curious what's your experience will be.
