Would be interesting to analyze what ship-placement strategy/distribution makes the opponent indifferent in terms of which cell to shot.

More likely because both are Africans...The commentor is ignorant, we don't need to paint him as racist too lol...
greenbay20··on Show HN: I built an online interactive course that helps you learn Vim faster
Awesome idea, gamifying learning vim seems the way to go.

Minor detail: I would recommend you set up the keyboard focus on the game as soon as the page loads. Saw a comment mentioning that the HJKL keys were not working and the same happened to me...right until I clicked on the command-line box in order to have my keyboard focus it.

greenbay20··on Launch HN: Jika (YC S20) – Price A/B Testing for Shopify
This is dope. As close as one can be to the money, niched down and in a growing market. Good job! Keep us updated =D
greenbay20··on Launch HN: Jika (YC S20) – Price A/B Testing for Shopify
I'm incredibly disappointed this was the top comment. Instead of asking whatever it is you want to know in an optimistic way, you just threw a random comment that with decent chance just makes the OP feel worse.

For starters, a really simple question you could have asked that may update your belief of how weird it is they got into YC: "How much money are they making and how much are they growing per week?"

I don't think people should try to price in stock value "growth" into the equation. The fair value today of the stock you're promised on the nth year is just the price of the stock today (for publicly traded companies).
greenbay20··on Show HN: Hero – Superhuman for Task Management
Hero is a chrome extension to manage your tasks and help you focus on one task at a time. Several features are designed to help you focus on exactly one task at a time: 1. You can create a task with a wake-up time from anywhere in Chrome under 10s. 2. Only one task can be "awake" at a given time. 3. The woken task has its own tab and its text is shown every time you open a new tab.

We've had decent growth the past 12 weeks, from ~100 tasks created per week to 1432 this past week. We're looking to expand our pool of 60 users, so if you're interested, schedule an onboarding with us through our website and one of the two co-founders will onboard you on a 15-min Zoom call.

Thanks for reading this far :) -Fernando

If you die instantaneously, your death-bed regret is 0, right?

Thanks for sharing! Sounds very similar to Bezos' mentality.

I don’t get it :S
greenbay20··on A Counterintuitive Probability Game
Note that the paper claims that no matter how player A chooses the two numbers to write down, you can always guarantee >50% chance in guessing which one is the higher one after only looking at one of the numbers. The reason this seems counter-intuitive is that the only information you're given is one of the numbers. You are not told anything about how the first player picked her numbers. Now, the reason why OP's code does not seem counter-intuitive to most is that it shows a quite different result. The OP assumed a specific distribution (which is a strong assumption, one the paper does not make) and found a strategy that yields > 50%.

>> But for any two finite numbers, A and B, the chance that C will fall between them if selected from an infinite range is 1/infinity (or 0).

I think you're assuming we pick C uniformly at random from an infinite range, but this is not possible. In general, the claim is not true: consider picking C from a sample of a standard normal, if A = -B = 2 then with >95% C will lie between A and B.

Watch out everyone. The linked tweet has comments that point to what seems like a scam.
