Reminds me of this page with an example for understanding how many permutations there are for a shuffled deck of cards: https://czep.net/weblog/52cards.html

> So, just how large is it? Let's try to wrap our puny human brains around the magnitude of this number with a fun little theoretical exercise. Start a timer that will count down the number of seconds from 52! to 0. We're going to see how much fun we can have before the timer counts down all the way. Shall we play a game?

> Start by picking your favorite spot on the equator. You're going to walk around the world along the equator, but take a very leisurely pace of one step every billion years. The equatorial circumference of the Earth is 40,075,017 meters. Make sure to pack a deck of playing cards, so you can get in a few trillion hands of solitaire between steps. After you complete your round the world trip, remove one drop of water from the Pacific Ocean. Now do the same thing again: walk around the world at one billion years per step, removing one drop of water from the Pacific Ocean each time you circle the globe. The Pacific Ocean contains 707.6 million cubic kilometers of water. Continue until the ocean is empty. When it is, take one sheet of paper and place it flat on the ground. Now, fill the ocean back up and start the entire process all over again, adding a sheet of paper to the stack each time you’ve emptied the ocean. Do this until the stack of paper reaches from the Earth to the Sun. Take a glance at the timer, you will see that the three left-most digits haven’t even changed. You still have 8.063e67 more seconds to go. 1 Astronomical Unit, the distance from the Earth to the Sun, is defined as 149,597,870.691 kilometers. So, take the stack of papers down and do it all over again. One thousand times more. Unfortunately, that still won’t do it. There are still more than 5.385e67 seconds remaining. You’re just about a third of the way done.


Damn, I got the paper stack wet with all that ocean water. Guess I'm starting again from scratch...

I had a very similar experience releasing a video game. Barely anybody downloaded it because I didn’t put any effort into marketing/promoting, but “I couldn’t be happier with my journey in making it”. I have replayed it a few times and it makes me unreasonably happy (although I’m taking a break now because I want to forget where everything is on the map).


Care to share the link? I'd like to take a look.


> Who are we to believe - the repliers, or our own lying eyes?

Believe the repliers: I created an account in May 2024 and I have not added a phone number. Here's a screenshot from my settings: https://imgur.com/a/Q7kJpDv

But also, your eyes aren't lying to you: some servers require accounts to have confirmed phone number in order to join. So there is probably a lot of people who have had the experience of creating a Discord account, trying to join a server / accept an invite, and immediately seeing a "you must provide a phone number" prompt.


The youtube channel Summoning Salt made a great video that covers the history of Tetris world records: https://www.youtube.com/watch?v=mOJlg8g8_yw


Highly recommend Summoning Salt in general. I never thought I'd find video game speed runs, records, etc, interesting, but his videos end up being very entertaining. His pacing, tone, and the way he works in music are very effective.


> I'm curious how this can be applied with the inevitable combinatorial exhaustion that will happen with musical aspects such as melody, chord progression, and rhythm.

https://www.vice.com/en/article/musicians-algorithmically-ge...

They did this in 2020. The article points out that "Whether this tactic actually works in court remains to be seen" and I haven't been following along with the story, so I don't know the current status.


> still being as faithful to the original as it could be

Wow, you weren't kidding - it's basically a note-for-note cover of the whole album. Thanks for sharing the link!


> Although it has been on my mind for a long time, I haven’t been able to read a comprehensive book based on these studies

Deep Work by Cal Newport focuses on these ideas pretty heavily, and he cites plenty of studies to back up his arguments. Like the author of the blogpost says, "There’s no guarantee that what works for them will work for you", but I found my productivity increased noticeably after I applied some of the advice from the book.


I released a game using OCaml bindings to the Raylib library. I had never written OCaml before and I didn't spend very much time refactoring, so the code is pretty messy and maybe isn't the best example of the language. But some of it turned out pretty nice - the first ~90 lines of this file detect collisions between two shapes using the Separating Axis theorem: https://github.com/mega-dean/hallowdale/blob/main/src/collis...


In 2008/2009, I bought a DVD of this movie called "The Fall": https://en.wikipedia.org/wiki/The_Fall_(2006_film) . I'm a sucker for visually-appealing films so I loved it, but I eventually lost the DVD and was never able to find another copy, despite checking every year or two. The wikipedia page says:

> As of September 2023, The Fall had been unavailable on streaming services or rental services, making it notoriously difficult to access with secondhand Blu-ray copies of the film being very expensive.

But apparently that isn't the case anymore! MUBI bought the rights earlier this year, and it looks like I can watch it through Amazon Video if I sign up for a MUBI trial.

EDIT: I maybe should have visited https://mubi.com/ before commenting - clips from The Fall is the very first thing they show.


> Does anybody smarter have a good point of re-assurance?

I'm not very smart, but I don't think you need to worry about drones using the linked flamethrower attachment: in order to buy from the website, the terrorist needs to click the "Agree" checkbox that says "I understand that operating a drone or UAS in the US with this attachment would require a Part 107 Waiver."

This page has some information about operating drones over people: https://www.faa.gov/uas/commercial_operators/operations_over... . That page says "the remote pilot must take steps using a safety risk-based approach to ensure that ... the small UAS is not operated in a careless or reckless manner so as to endanger the life or property of another (§ 107.23)". So IIUC, I think it's likely that the FAA would deny the application for the Part 107 Waiver, and the terrorist wouldn't be able to use it.

Hope that helps!


I’m 99% sure you’re joking… but since this is the internet, I’ll say it explicitly: obviously the terrorist would check the box, never bother applying for FAA waiver, and fly the drone anyway.


That would be breaking the law, however, which is against the law.


Much like the beloved US Visa question "are you a terrorist? y/n"
