Could some people please review the following tag edit suggestion. This edit needs to be rejected in order for me to propose a new one. I was going to copy/modify the tag from Stack Overflow.

This answer seems to be the popular definition of "programming language". I propose that a combination of image canvases and the fx operator available in ImageMagick satisfies this definition.
The language must:

@PhiNotPi I like the idea, but its not really Codebots unless there is competitive writing. Perhaps the bots aren't "owned" by anybody, and people are able to write X pieces of code?
I'm not sure how the game works, but even without competitive writing, it sounds like a good idea
There is a little bit of "hacking" though, in that there will be a ZAP command, which causes your next command to be executed by the bot in front of you.
sheesh, is this really the 4th? For all you oldcomers, the core challenge is the same, but we are using Java instead of a custom language. Here are the past three CodeBot challenges, in case you are interested.
The goal of CodeBots is to make your bot as viral as possible. Each bot carries a ...
The challenge
This challenge is very simple: print the longest line of code with the shortest code. However, your code must be less than or equal to 100 bytes, and you must be printing a string.
Scoring
Your score is the number of bytes printed to the console minus the number of bytes of your...
Answering the election questionnaire got me thinking: in addition to having an objective winning criterion, all challenges also need an objective validity criterion — there's no point in comparing answers if there's a fuzzy line of what even constitutes a valid answer. This has come up several ti...
@MartinBüttner Nice. It doesn't help me though, since I needed it to work with non-empty input. Your other one still works (though there's a bunch of semicolons)
Retina, 81 bytes (not competing)
The language (especially the Sort mode) is newer than the challenge.

Your challenge is to passwordify the string! What is passwordifying, you ask?
Take a string as input. This string will only contain uppercase letters, lowercase letters, positive integers, and spaces.
You must replace all spaces with underscores and move all numbers to the end of the string in...
So wikipedia gets around ~15b pageviews per month. They usually show the banner for like a month, each pageview requires half a second of scrolling to get past the banner, that's 7.5b seconds wasted, or 237 years. Everytime wikipedia shows the banner they waste the life equivalent of around 3 human lives.
Alice and Bob are playing a little game. First, they draw a tree from a root node (indicated by a thick dot), with no internal nodes, with numbers at the leaves. Any node may have any number of children.
We start at the root, and first to play is Alice (A). She must select one of the current n...

The community on PE generally prefers that people figure out the solutions to problems themselves. Having those problems on PPCG would defeat that purpose.
@El'endiaStarman I like your attitude on this. I should mention that some students posed homework questions to SO. When I complained to some high rep SO people they said that was a great thing and it was what SO was for!
This question is specifically prompted by my using ImageMagick in a challenge, but applies in general. This is somewhat an extension of
All of the IM tools take the same syntax of operations and expressions. However, each tool has a different name and a different default behavior.

The crucial problem (I think) with homework questions on SO is when people just give the solution outright, so the student doesn't have to do any work. This is a problem on Math too (and Physics, I'd presume).
They also had to fiddle with a couple details of the spec (like the "input" numbers) so that it's not too easy.
I think you're generally always going to have heavy CPU usage. That's just the nature of programs that solve math problems by looking at a lot of numbers.
@easterlyirk They probably won't care about random challenges; if you've actually worked on developing a language and that has a Github page or something similar, that could be good as an example of work
@easterlyirk Also, it depends on how old you are. If you're fairly young, they'd be impressed by the interest you have in languages, whereas if you're older, they're looking for more professional, realistic work
I'm probably going to withdraw in a few days anyways: the pro-tems are gonna crush this election (as they deserve to) and if on the off chance I actually win I will probably feel guilty for displacing a protem anyways
.oO(I wanted to post a photo of our cat that I took today, because she looks a lot like the cat in the above picture! But I suspect the image upload thingy doesn't do EXIF stripping, and I don't want the geotagging for all the world to see. So. :-P)
> Space Travel Because the red panda is not much larger than a house cat, and therefore definitely smaller than the average house dog, it would seem to be ideally suited for space travel following the experiments performed by the early Russian space program. Their reliance on bamboo as their primary foodsource is well suited to long distance voyaging, as it is easy to store for lengthy periods without deterioration.[38] Despite this, widespread adoption of these animals as astronauts has not been reported.
I may be misremembering this, but I think it was John Carmack who said that the reason to use strongly typed languages is that "every error that is syntactically valid will end up in your code base if your project is big enough". And strong typing allows to compiler to catch more potential errors before your program ever runs.

lS'_er{60<}${eu_el+mR}%
Test it here.
Explanation
l e# Read input.
S'_er e# Turn spaces into underscores.
{60<}$ e# Sort (stably) by whether the character is a digit or not. This moves digits
e# to the end, without changing the relative order within digits or ...
Strong typing also really helps with making sure pieces fit together for a large-scale project - you have to explicitly spell out some contracts that you would forget to document otherwise
Haskell's type system is awesome. It's somehow really strict (so catches lots of potential bugs) and really flexible (you can easily define complex types) at the same time.
I don't know... I just never really liked the syntax... compared with Mathematica, it just seems a bit shoddy for proprietary software :D (I know it's good at what it does, but it just seems a bit... antiquated... I don't know...)
