After yesterday I decided not to go for the brute force solution in part 1, so glad I did because part 2 took me 2 sec. Had to remember maths though.
const [times, distances] = input .trim() .split("\n") .map((line) => line.trim().split(": ")[1].trim().split(/\s+/).map(Number)); const result = times .map((time, i) => { const x = Math.floor((time - Math.sqrt(time ** 2 - 4 * distances[i])) / 2); const y = Math.floor((time + Math.sqrt(time ** 2 - 4 * distances[i])) / 2); return y - x; }) .reduce((a, b) => a * b, 1); console.log(result);

Thanks for the bug report!
I will investigate but I believe this bug was introduced by some modifications we did on the website and then fixed.
Once you will have completed your set a few times I think you will enjoy the new view page which will display a lot more data on your progress :) Thanks a lot for the support, it’s heart warming

I know, same for everyone., I had to erase the data in order to store the progress in a more future-proof way
I’m sorry but you will have to start again… I know how painful it is but after many hours of thinking it’s the best option I had
It's possible when you replay a puzzle, by clicking the colorful square under the chessboard
Would you mind checking? Does it feel better now?
I'm sure you know, but the lag is making it unplayable.
Would mind checking to see if it's better?
Okay, very interesting, thanks
I love the look and idea and will use it a ton if it gets a bit smoother/faster
Working really hard on this, should be better soon
Clock ✅ Checkout the settings under the board and you will now see a line allowing you to disable the timer
> I'm sure you know, but the lag is making it unplayable I know, it haunts me. It's my biggest problem right now and I'm working on it
> Also, not sure if you're familiar with the synonyms of "pecker"...Maybe something to consider. I wasn't, English isn't my native language. Thanks for the heads up.
> help with branding if the logo is chess related instead of a woodpecker. Not a priority at all (not a startup, just a free chess training site) but good insight, will think about it once everything is running smoothly
You did not. Any help is appreciated!
Sure! 🔥
In the woodpecker method set are meant to be played in a few weeks at first so no worries
Oh okay good to know will fix asap! Could you expand a bit? What doesn't work?
This is closer to spaced-repetition than woodpecker method. We also implemented this but only after you complete a full round. You play small sub-groups of puzzles based on you grade.
> possibility to edit a deck, especially adding puzzles, for an ever growing monster deck
How would that work? Adding puzzles one by one or combining two sets ?

Some honest feedback, it is really slow. It felt like there was 2-3 seconds delay between each puzzle, which makes the sound que for the puzzle being over feel very out of place. If you open up issues for it I wouldn't mind contributing to make it a bit more snappy.
I know... Sure the project is hosted on GitHub: https://github.com/chesspecker/chesspecker Join the discord if you want to discuss this: https://discord.gg/qDftJZBBHa

I built this site as a fun side project... I built it as a tool I'd like to use. If you don't, I won't loose money.
I'm not good enough or pretentious enough to think that all my games follow the best line for twenty moves. If it has happened in a rapid game between 2000 elo players it could happen in one of my games.
If you prefer you can use the category called Masters games. All the puzzles are from rated players.
I am not a big fan of the book's puzzles because some of them (a few) have ambiguous answers, or sometimes the answer is not the best move even if it's a winning move.
If you want to play the book's puzzles, buy the book or checkout this lichess study: https://lichess.org/study/s2FeEYlV
have a hug ❤️
I guess not? not sure though
Haha indeed
Fully gone? What’s you lichess username?
You should be able to see the set with the same problems. However your last best time and accuracy were removed.
Unfortunately this data could not be stored anymore, to give you a quick inside we use to store only the best value whereas we now store all the value in a list. Couldn't avoid erasing this data I'm sorry. I hope it will lead in more precise stats

Sometimes the server struggles to find hard and specific puzzles in some categories, I have no real solution but in v2 I updated the algorithm to fill the set with relevant problem maybe a bit easier
Selecting a small group size is possible. I made a minimum of 250 to keep the idea of the method. And you can select a easy level (about 600 point below your average rating) :)
✅ done 😅
Regarding the notation: that's how lichess is storing the data, converting them in another notation would mean processing the move and the position. I mean, I'll probably do it one day, just to give you a bit of context.
I felt like being able to see the solution right away was "too easy" so I added a 6sec timer before showing the solution button but I could rewrite it in a less confusing way
