Random Physics Golf #1: Net Gravitational Force code-golf math
Introduction to the Series
Every week or so I will be posting a physics challenge. My goal here is to design challenges that in the end, teach some people some physics. Overall, the challenges will be very basic with little informat...
Introduction
Compute is a esoteric joke language.
From the esolangs entry:
Compute has no required syntax and has the power to solve any and all
problems. It is smart enough to interpret any human language (English,
Spanish, Latin, etc), any programming language (C++, Java, brainfuck,

This feature request is related to PPCG not being a Q&A site.
The most important part of the onboarding experience for new users (especially those who don't arrive via other sites from the network) is the tour page. Moderators can customise the first paragraph and a few details in the right colu...
@Martin @Dennis @Doorknob @quartata Have you guys never had experiences with companies/customer service where you are kind of just forgotten about? Not necessarily on purpose, but somehow your call/request/appointment slips through the cracks and they don't respond? Idk if that's what's happening here with Grace Note/SE but I'd rather be a little annoying and have the problem solved than be completely placid and have to wait who knows how long.
@MartinBüttner Ok. But at least one CM did know of the issue over a month ago, and did not necessarily do anything about it besides glance at our A51 page. (And did not respond to follow up comments.)
@Calvin'sHobbies I don't think it's inappropriate so much as unnecessary. Then again, I'm of the opinion that they'll get back to us as soon as they figure out why we hadn't triggered their eligibility flag.
Yes. Honestly I feel like that wouldn't be as drastic of a change as you might think; we haven't had any successful pop cons in a year and the good ones can be historically locked.
@quartata I recall seeing a meta post where "objective pop-con" is argued to mean judging the code rather than the output. (Kinda vague still, but it's a start.)
I want to open a discussion about this recent highly-popular question that has been closed and reopened a few times: Animation of Code Golf.
The turbulence of that question and similar past questions is clearly related to the fact that there is disagreement on whether "art contests" can be progr...
The thing is, people vote how they want to vote. We can recommend they vote based on a certain set of criteria, but in the end, they'll do what they please.
> I'm perfectly happy with a question where judging is based purely on the output, provided that the implementation is the reason for that output being appealing or impressive. If the output is incidental to the implementation then I would want the question to be closed.
This means things like images with all colors are valid
I personally think that popularity contests are inherently flawed. You can write a perfect challenge, focused on programming, with a clearly defined task, an objective validity criterion, and clearly established voting guidelines... and people will still vote for whatever the heck they want to.
@AlexA. Agreed. Challenges like those make this site accessible to people who aren't really interested in implementations. It would be overly stingy and detrimental to ban pop-cons altogether.
@Dennis I see your point, but to be fair, everyone answering a pop cons knows their win chances are at the whim of the masses. Hasn't seemed to slow down many well asked pop-cons.
Similar to the images on allrgb.com, Make images where each pixel is a unique color (no color is used twice and no color is missing).
Give a program that generates such an image, along with a screenshot or file of the output (upload as PNG).
Create the image purely algorithmically.
Image must ...
I don't think you could, really. Not without actually modifying the site. A userscript would only be as effective as it's installed base ratio to total voters :/
@El'endiaStarman Nice. I also appreciate the comment someone left regarding the alternative removal technique with the shockwaves that break up the ink rather than the heat.
Nice, haha :) Before I posted it in the sandbox, I managed to get one working in JS (kind of right on the line of valid, because working with newlines/new messages in the console is tricky)
1-up your average quine
code-golf quine
A 1-up quine is a program which is very similar to a quine. The one major difference is that instead of printing itself once, when n copies of the code are concatenated, the result prints the code n+1 times.
Example
If your code is Abc123:
Abc123 -> ...
@Dennis No, I wan't you to prove that each sequence ends. While you're at it, prove the collatz sequence's termination. :P Of course you're allowed to assume it ends. — Seadrus52 secs ago

I've only implemented 2-tag systems and Rule 101 to prove Turing-completeness. I still want to implement a Brainfuck interpreter at some point... (although it currently won't be able to support infinite input, nor output in non-terminating programs)
Probably still around 60 bytes, easily. Maybe closer to 100.
I talked to randomra about this a couple of days ago.
I'd like to make this easier by providing some sort of built-in, but I don't want it to be a plain "transpose" built-in. I'd rather add a feature that makes it possible in ~10-20 bytes but which is flexible enough to allow for other transformations as well.
code-challenge string
Auto BATCH golfer.
I love BATCH, despite its shocking lack of functional commands, despite even due to its lack of non-integer support. Why? Because this works:
SET var=SET
%var% i=0
This would evaluate to:
SET var=SET
SET i=0
Fantastic, isn't it? I've used this tech...
Any objections?
@Seadrus are generators fine for your juggler challenge?
Add a workaround to the doc, only to find out that it doesn't work after a while since people are so used to getting out and back in that they do it too fast
Is this a good challenge idea? Print the message "Happy Valentine's day, <language name>" exactly, where <language name> is the previous submission's language of choice.
@AlexA. Why do "nerds" generally dislike watching sports? I've never loved them but I've realized that part of the appeal could be that (ideally) they're the most "honest" thing on tv (e.g. vs biased news, staged reality shows, fictional sitcoms), and I can respect that.
@Calvin'sHobbies Sports just don't appeal to me that much. I can appreciate the athletic abilities of the participants and I like it when the Seahawks win things but overall... meh.
@Roujo Which makes the whole thing a lot less interesting. I watch football (the kind you play witha ball and your feet) every two years when there's a World or Euro cup, but not even once in between.
@Calvin'sHobbies I went to a basketball game last week, and had much fun. I hadn't been to any live sports event since I was 10 or something, and don't really follow any sports either.
My girlfriend showed me a video of a guy playing a cricket videogame and he said, "I've been playing this for 30 minutes and I still don't understand the controls. Or the sport."
Diopter lenses
In photography, there are thin lenses that you put in front of a photographic lens to make it behave like a close-up lens. Each of these lenses has an associated diopter value which is a positive integer. If you stack two (or more) of these lenses you get an equivalent of a lens w...
