Show HN: Unsure Calculator – back-of-a-napkin probabilistic calculator
https://qalculate.github.io can do this also for as long as I've used it (only a couple years to be fair). I've got it on my phone, my laptop, even my server with the qalc command. Super convenient, supports everything from unit conversion to uncertainty tracking
The histogram is neat, I don't think qalc has that. On the other hand, it took 8 seconds to calculate the default (exceedingly trivial) example. Is that JavaScript, or is the server currently very busy?

"A calculator app? Anyone could make that."
I use qalculate, it behaves well enough for my needs.

Students, what features would you like to see on Windows 12?
1) a scientific calculator with history and variables with a UI similar to https://sourceforge.net/projects/alt1-calculator/ that also can do units like https://qalculate.github.io/ 2) a tiny text chat direct message program that is similarly as easily accessible at Atl1 3) a minimalist dock of as many instances you would like similar to https://punklabs.com/rocketdock, and like where WIN opens the start menu, WIN + # should pop the dock

New world record with an electric racing car: From 0 to 100 in 0.956 seconds
But unfortunately gravity is the first unit that I find is not supported :(
There's some talk about using g0 here https://github.com/Qalculate/libqalculate/issues/498 but that doesn't work in my version (I'm using an old version, hoping to update my OS this week). You can divide it by earth gravity if you know it by heart, though
> 100 km/h / 0.956 s / 9.8 m/s^2

GNU Units
I personally use Qalculate (https://qalculate.github.io/), specifically their CLI version for this purpose. I'm not sure how well it compares to GNU Units, but it works well enough for my needs; and it's fairly simple using English-like syntax.

Ask HN: Do you still use a hand held/desktop calculator?
On the terminal, I use `qalc`[1]. It's a nice natural language calculator that does arithmetic, solves quadratic equations/linear systems, does unit conversions and even a bit of calculus. Combine it with a cli graphing tool and you can do pretty cool things.
Anything more complicated I'm probably ok with latency, so I open up wolframalpha and enter it there, again, in natural language.

[Conversion] I need an explanation for this question please
Btw, download qalculate.github.io and play around with it a bit. I use it for basically all the physics I do. Complete lifesaver.

Calculator for sway
Personally I use http://qalculate.github.io/ since I end up having to do unit conversions often, it's pretty handy for that
