Looks nice. Feedback: I was trying to enter "1000$" and "12%" (in the loan calculator) and it rejected my inputs ("Loan amount must be a positive number" and "Interest rate must be between 0 and 100") - could you just make it a bit more forgiving, if the units $ or % are included in the user input?

You're not the only one. I recently took up running and didn't particularly like any of the existing running pace calculators, so I made my own: https://calcubest.com/health/runningpace And then kinda realized that there were others I wanted to have, and a few I thought others might want, so I added more. A calculator is simple enough that it's fun to work on one when I need a break from something more complex but wa…

To anyone thinking of starting running but either doesn't know where to start or thinks he can't do it, look up "couch to 5k". It's a free NHS audio program that guides your phase so that in 9 weeks you can do a 5k run.

I can second this. That's the program I started with. I'm now training for a half marathon using https://www.baa.org/races/baa-half-marathon/train/leveltwo and I've shaved like a minute off my mile pace while increasing my milage from 6 mile runs to 12 mile runs.

There's lots of programs for running and most of them seem good for improving performance.

This is very different, but check out my https://git.sr.ht/~akkartik/notebook.love

I don't have an immediate use for it, but I quite like it!

Me neither and me too! Thanks :)

If you're taking suggestions, I have a frequent need to do basic arithmetic on fractions and not many "app" calculators do that well or at all.

On the desktop, if you keep a Scheme interpreter installed, you can use it as a quick arbitrary-precision calculator, including support for fractions. Guile is the most easily available one on a Linux system, though some others will give better REPL out of the box. $ guile GNU Guile 3.0.8 Copyright (C) 1995-2021 Free Software Foundation, Inc.

Heh, I hated writing arithmetic in lisp even when I used it fulltime with paredit.

Fortunately, many languages have a rational type, even Python, which might be more ergonomic even if ratio literals aren't supported:

    $ python
    from fractions import Fraction as f
    f(1, 2) + f(1, 8) + f(1, 8) 
    # 3/4

Suggestions:

- Fix your certs to not lose traffic when Chrome (at least at the default security level) puts up a scary "Your connection is not private" warning for net::ERR_CERT_AUTHORITY_INVALID and requires an override to proceed to your site.

- Fix whatever reputation damage has caused you to be classified as a phishing site: https://phish.opendns.com/main?url=www.calcverse.live

You didn't like the parentheses and prefix operator syntax?

Syntax-wise, you could use Racket (or another Scheme, with a little more difficulty) to make a very thin layer over normal Scheme, and package it into a program called `calc`, like this:

    user@computer:~$ calc

    > 1/2 + 1/8 + 1/8
    $1 = 3/4
    >
Or do you want a bigger library of off-the-shelf numeric tools, like Python, Julia, or R?

Just a side question but "while the rest of the world builds ai systems" makes me curious about what rough percentage of software engineers out there are working directly on building AI systems, even just on a front end level.

Assuming there's not an easily access exact percentage, just curious what people's perceptions are.
