Is ChatGPT the helper or the welder?

It guessed my lichess almost rating exactly. Impressive!

Lol

Sorry! It's back!

Had to upgrade my firebase plan...

Yep

I was using it as the database to track results, but I guess we went over the limit. Fun problem to have! But it's back up.

I'm not a developer, so it's a real testament to how good and simple a framework SvelteKit.

Inspired by Matt Levine's awesome reporting on the Elon/Twitter purchase fiasco. Just a little app to model the arbitrage (gamble) opportunity.

For those looking for the simple to understand solutions:

Bertrand’s box paradox:

The trick here is that you are not actually drawing a card, but a card side. There are 3 cards, but each card has two sides so there are 6 card sides and half of those sides are white.

So, now we have to pick one of the 3 white card sides at random. Of those 3, 2 have white on the other side and one has black. Therefore, if you pick a white side at random, there is a 2/3 chance that it is white on the other side.

Monty Hall Problem:

Say you're going to switch no matter what. Then the only way you can lose is if you pick the right door on your first try - a 1/3 chance. Conversely, as long as you pick either of two wrong doors first you win. Therefore, you have a 2/3 chance of winning if you switch vs a 1/3 chance if you stick with your original pick.
