@ngn Well, they aren't really making any breakthroughs, are they? They're taking tech that other people have done the research for, and making it more easilly accessible to everyday people through Q#.
@ASCII-only I would count it as an alternative model of computation, yes. I don't know much about it other than the general idea. It's not MPC though, is it?
The website of the company I work at was loading really slowly for everyone and no one could figure out why for months. Today it was discovered we were using an extremely high resolution version of our logo that was 80 megabytes.
On the bright side, it got our front-end dev to drop some entirely unneeded JS libraries in the hopes of boosting speed. I think the entire site has less than 200 lines of javascript for the entire thing and we were loading JQuery for it.
Are there mountain rings? code-golf matrix
Challenge
Given a matrix of positive integers, determine if there are any "rings" of mountains. The formal definition for this challenge is: given a 2D list of positive integers, is there any non-negative integer n for which there is a closed ring of c...
Is this a truncated triangular number?

Truncated triangle number
A common property of triangular numbers is that they can be arranged in a triangle. For instance, take 15:

o o o

We all know of, or at least have heard of, brainfuck, one of the most famous and influential esotoric languages. While these days most implementations use an infinite tape, the original compiler by Urban Müller had a tape of 30000 cells. A little known fact* is that there is actually a special va...
There was some technology that allowed for the creation of "perfectly looping" GIFs, but I can't remember the name of it.
Like it segmented each frame of video into independent parts, finding the best places to cut and make a gif, allowing different parts of the gif to loop at different rates.
Hmm.. there might be a few projects that attempt to make perfectly looping gifs.
The project I'm thinking of definitely involved something more complex than just finding optimal start/ending frames though.

Take a positive integer N as input, and output a matrix with the numbers 1 - N^2 that follows the pattern below:
Fill in the first row with 1-N then fill the last row (row number N) with (N+1)-2N, then fill the second row with (2N+1)-3...

Input:
An integer n (> 0)
An integer-array a of size > 0 (which contains positive and negative values, but no zeroes)
Output:
First output the first n items
Then take the last item you've outputted (let's call it e), and go e steps forward if e is positive, or abs(e) steps backw...

actually, I don't think augmented assignment is the way to go
however, something that lets you do something while only referring each variable used once would be useful
for example, some kind of eval that replaces occurrences of each variable by its value when referenced, and then get the variables as separate arguments
BTW I'm remaking Neutrino because the old implementation (which was just copy-pasted from Enlist) doesn't allow for things like "last link as n-adic link" to be (properly) implemented (I could do it but it would be really hacky and dumb and inconvenient and probably would end up breaking anyway)
noooo, I've got a proper Heisenbug... when I run the code in a debugger, the bug vanishes and when I attach a memory error detection tool, the bug changes -_-
@user202729 Your comments on the latest NMP are, in my opinion, hovering at the edge of what would still be considered Be Nice. You don't need to sound so condescending to a new user to the site.
Consider that most people don't read the help center. Sure, that's their problem, but expecting people to have read it is usually not a good idea because that's usually not the case (and if they did, they probably would know not to post help questions to our site)
I would also think that in that case, since they're supposed to write a palindrome program, their confusion about which site to use is easier to understand
@user202729 Two things in particular in the comments on this post. The first, "Do you understand what this site is for?" and the second your quote about SO not being a place to ask for help. Both sound, in my opinion, very condescending.
We say a string is non-discriminating iff each of the string's characters appears the same number of times and at least twice.
Examples
"aa!1 1 !a !1" is non-discriminating because each of the characters , !, a and 1 appear three times.
"abbaabb" is not non-discriminating because b appears mo...
@user202729 condescending kind of means you're talking to people as inferiors
or at least your tone makes it sound as such
I personally find "Do you understand what this site is for?" to be just a question of "Do you understand or do you need some help with that?", and I don't find the tone to have any problems with it, but it could just have to do with different interpretations.
don't know how I missed the part about the program itself needing to be non-discriminating ._.
like basically as you run through the program the left and right argument values change, the most recent value is printed
if you have a nilad and then another nilad, the first nilad is printed because the second nilad won't be able to fit with the first nilad in terms of argument values (assuming there is no dyad-nilad or nilad-dyad chain)
What...? The version with both ( and ) and infinite width is undecidable. If you don't believe that I will implement a TC language there. (of course I can't)
