Hi Friend - I tried that yesterday and it didn't get any upvotes so sent it out as a newsletter. I don't know what dang thinks of replacing the link once it's on the front page. Happy to do it (or have him replace it). (https://news.ycombinator.com/item?id=39133955)
You are absolutely owed upvotes on your special post. It says a lot about the state of the world and society in general that your first time posting didn’t get the upvotes you think it should have.
I applaud, starting with a slow clap and transitioning to uproarious applause, your smart trick of hacking the system by sending out a newsletter devoid of content to ensure people saw your content got the upvotes it deserved, and salute your magnanimity in this follow up post.
If you are unfamiliar with Jane Street, it is a quantitative trading firm and global liquidity provider focusing on using sophisticated quantitative analysis and a deep understanding of market mechanics to help keep prices consistent and reliable.
Gosh, it's practically a charity. I didn't realize.
They provide a service to the market and that’s just a pretty basic description of it. Obviously they hope to make money from doing so, but so does every company.
No different to saying McDonald’s focuses on delivering quick and easy food to customers.
Super fun game. I really wish there were a larger online community that plays it. Jane Street made a great website for playing it online: https://figgie.com/. But alas, there's pretty much never anyone online to play against.
Anytime I see something about Jane Street, I would like to remind folks that they discriminate based on what school you go to. Be forewarned. If you aren't in their angel pick list, you're autorejected.
I wonder if they really use OCaml for the reasons they state, or because it used to top the computer language benchmark game back when the firm was founded and now it's too expensive to rewrite everything.
How do you do the card setup if you were to play at home? Seems hard to, in practice, randomly shuffle the 4 suits, then pull cards, then shuffle together without exposing information about the target suit. Interestingly I couldn't find a video of people playing.
> - Turn the piles face down and shuffle the piles so that the piles stay together but you no longer know which pile is which suit
This is the specific part I'm actually concerned with. It is difficult to shuffle piles without accidentally exposing information. Cards can slide and there's so few "bins" that your brain can easily track, even by accident. The rest is easy and standard.
One simple solution: just put 12 cards from each suit into 4 piles and then hand the piles to somebody else who didn't see which pile is which suit for them to do the card removal and then the final shuffle that merges the piles.
So basically a two-person deal where each dealer does a different step lets both people play without knowledge of which suit is the target suit.

Have fun.
The best option I could think of:
- Create 4 piles of 12 cards for each suit
- Turn the piles face down and shuffle the piles so that the piles stay together but you no longer know which pile is which suit
- Remove 2 cards from 2 piles and 4 cards from one pile
- You now have suit piles of 12, 10, 10, and 8 cards
- Shuffle them all together and deal
- You’ll know what the target suit was by looking at the cards at the end of the round
Slow, but I think it would work.
