Solid platform - clean and useful for algorithm practice.

Quick suggestions:

  - GitHub OAuth would feel natural for devs.
  - Broaden language support (C#, TypeScript, Ruby).
  - Add dark/light mode toggle for comfort.
Excited to see where it goes — thanks for building.

I like the idea, and you've got yourself a customer :) The lifetime membership + launch discount was a good marketing bait I felt for. Not really understanding the negativity here. We know for a fact that most of the people that master intellectual problems do so via pattern recognition, not by reasoning. You show a chess master a position, he/she can instantly tell you what the best moves are without "thinking" or "…

> Not really understanding the negativity here. In the last year or so HN seems to have attracted a lot of people (plus some bots) who seem to have been socialized on Reddit. I don't know if these people are ignorant of what a good discussion forum can be (because they've never experienced one) or just don't care, but I do wish we could see more reflection on the second-order impacts of posting, and a move away from…

I've been around here for over a decade. I'm telling you, this has been happening for longer than a year. I'd say the last ~4 years.

Some feedback: The drill style approach seems helpful, but needing the variable names to exactly match threw me off. It would be great if we could _relax_ this constraint via a toggle for drill mode. "Precision Mode" feels like it's misnamed; when it's toggled on it feels more like a "guided mode" since chunks of boilerplate are written for you. It would be great if exiting Drill mode remembered choices, such as what portions were selected.

Ended up deciding to buy a subscription, but looks like the site still says "82% claimed" and "17 spots left". I appreciate the one-time purchase model, but feel that it's a bit shady of a tactic.

I learned the other day ( https://news.ycombinator.com/item?id=46184676 ) that people who aren't students apparently use LeetCode too, for recreational purposes? I'm not sure why you'd work on someone else's imaginary problem instead of doing something for yourself, so apparently it's there and some people enjoy it, regardless of my understanding of it. But then I don't know how to reconcile the idea that some people…

Seeing how other people solve problems opens up new ways for me to solve my own. Many people are not RTFM but instead want applied examples.

Yeah, this is me very much to the core of my bones, and I think that's why I don't find any pleasure or enjoyment from these synthetic coding challenges, and trying to understand those that do.

This might be the answer for me, you're breaking down all these questions into actual smaller steps and having the user write those out instead .

I dislike limited offers, because I think you're placing a bit of unfair pressure on the user to buy. But I went ahead and gave you 30 bucks.

I'm going to study this before my next interview, thank you

What threw me off is the expectation that I use the same variable names and exact same code structure. There are many ways to implement effectively the same thing. I understand that it would be very challenging to implement a way to validate solutions in this way, but memorizing exact fragments of code feels like it's optimizing for the wrong thing.

Some might consider that a kind of commentary on the leet code interview format.

After hearing people complain about these fearsome "leetcode interviews" for what feels like a decade now, I have to wonder when I am finally going to encounter one. All I get are normal coding problems.

One man's leet code is another man's simple programming question which involves minimal domain knowledge...

I've had candidates describe what I'd loosely call "warm-up" questions as leet code problems. Thing like finding the largest integer in an array or figuring out if a word is a palindrome.

I feel like this is a bit backwards. It seems to be an improvement over just grinding LeetCode, but I'd never work for a company expecting me to spit out LeetCode solutions quickly (recall). If they give me a LeetCode style problem and want to see how I approach this, what I know, how I deal with what I don't, then it's fine. But I think neither LeetCode or AlgoDrill are needed for this.

Or to put it another way, if I give some applicant a coding problem to solve, and they just write down the solution, I didn't learn much about them except they memorized the solution to my problem. That most likely means I gave them the wrong (too easy) problem. It will only increase the change of me hiring them by a tiny bit.

Edit: I don't hate the player, I hate the game.
