hi! right now, it is manually assigned after parsing the problems. i am figuring out a relative system for assigning difficulty automatically.

I don't envy you the task! You've probably thought about it a lot more than me, but I was wondering if you could add a "very hard" or "advanced" category. Or perhaps users could submit difficulty ratings as a percentage and you take the average.

you are right, user-submitted content can help too. but that would imply a difficulty setting based on all users who have participated instead of a globally agreeable difficulty value. if the smart ones find a hard problem to be easy and they are the only ones to attempt that problem, that problem would be marked as easy.

on the "very hard"/"advanced" bit, feedback taken.

thank you for writing your thoughts!

cool. highly recommend to implement the review exercise style of https://www.executeprogram.com/ !, both the UI, albeit with better theming ( https://monkeytype.com/ ), and the spaced repition feature, all while keeping the hn styled comment section, although i'd let none-related comments run horizontally to click through different approaches/explanation(-styles). you got a startup there. keep it affordable. 5 bucks…

hahaha thanks! it is easy to put up a paywall but like you rightly pointed out, i'd love to make something worth paying for. until then, i don't know what direction this project will be taking. i'll keep iterating.

thanks for writing in!

Looks good, one quick thing: Maybe hide the comments behind a button? Now they are giving away the answer, as some have already posted it there in the first comments.

valid feedback. thanks, will add this!

To stay in touch with math, the annually publicized math problems from the German Abitur[0] are great! The problems are already separated into three difficulties, making it suitable to include in your website (although they might need translating).

so beautiful :) how much time did it take to build?

Thanks! I made it 2-3 years ago and IIRC it took me few months of weekend work; the things is that it was "easy" in the beginning, but for each combination of "feature" + "drawing type" things got a lot more complex, specially later on. e.g. when adding the option to shift the grid, or scale it, then I needed to change all of the drawing methods; or when I add a new drawing method, then it needs to work with all the…
