No more laser gun firing squad 😭

Thanks, it was a nice puzzle! I paused the video, thought about the problem, solved it by the next day, then came back. I was surprised that the main idea of my solution was essentially the same as in the original solution of Minsky and McCarthy shown in the video! And since I didn't think through all the technical details of odd numbers, it was satisfying to see it done in the animation. The only thing I would have added to the video is a table of the transition rules (just to see how complicated or simple their program is, for a second).

I assume the reupload is because the original "had guns"

pov u have to throw a surprise party and launch a buncha confetti simultaneously but you didn't have time to invite anyone else to help you throw the confetti and u have a row of random finite number of robots that shoot confetti and can only see the robots on either side of them and responding accordingly and you have to choose beforehand what finite number of states each robot can do and how they respond depending on what they and the robots on either side of them are doing where each robot changes states according to a set beat

I can not believe you re-rendered this amazing video, but anyway amazing job explaining this anyway because it's a perfect visualisation

*Comment reupload...* This is fantastic and I love it, but we are getting sorting algorithms soon as well, right? Sorry, it's my (and a lot of people's) favourite series

this should have at least a million views holy moly xD. very entertaining and interesting.

I've managed to make the robots count the row length. When i was solving the problem i approached it from the observation that the row leangth is unknown, and i (naively) thought that perhaps counting the row and encoding that information on the robots could aid in the solution. I simply took the rules of base 2 counting and translated them into symbols: Here's the basic idea: Let the initial symbol be A, and let there be 1 and 0. Let B→ and B← be directional hand signals. All robots start at 0. 1) Each period, if(A and not B←) the edge robot alternates between symbol 0 and 1 2) for non edges: If(A) then undo A and then if(left has A,1) then change 0 to 1 or vice versa, and display A. 3) the B signals travel to the end of the row and back (like the hand). When B← reaches the origin edge: if(A) it undoes A and continues, otherwise we are done. The second run of B is to give the other digits time to settle. now all the non edge robots display the digits of the count. By counting the steps required to get the B signal back we counted twice the length, and by ignoring the edge digit we can divided it by two to finally get the *length.*

6:50 beautiful, just beautiful

this beat is unironically fire

this reminds me so much of the soldier minigame on ffvii

Darn, I was assuming the robots could count and do math. I had the idea that a signal could be sent all the way to the far end, another signal could go back to the beginning, and then a third signal could go to the far end again, and with some math on the robots' part, they could all calculate where they were in line from how long it was between the first and second signals, so they could wait a certain number of beats after getting the third signal. Once the third signal reaches the last robot, they could all fire at once.

The lengths people will go to in order to avoid dealing with network protocols, even in the future

The video just isn't the same after replacing the laser guns with confetti guns. Totally ruined the experience for me.

Wake up honey new udiprod drop

Did you see the Veritasium video?

This is going to be epic! UPD: It is epic.

What happens if a robot has a broken leg - how to account for loss of part of a signal ? Would be nice to see a visualization of signal correction check digits.
