Squaring the circle
Background
This is a two part question, and a generalization of this question on puzzling.SE. Essentially, it asks you to generate a ring of integers such that any two adjacent integers add to a perfect square. The original question gave you a part of the ring. I wish to gen...
Find and execute a program from the internet code-golf internet
You have some task to do, but you are too lazy to do it yourself. Your also to lazy to make a program to do it. So you are going to make a program that finds a program to do the task you want.

@Adám how do you get the minor version of Dyalog running?

The challenge
Given two integers as input (x and y), output x as a string with as many leading zeroes necesary for it to be y characters long.
Rules
If x has more than y digits, output x as string without modification.
Output as integer is not accepted, even if there are no leading zeroes.

It can be a serious contender sometimes, it just has to be very well designed (if Pyth would have a code page, I think it would tear apart other languages sometimes)
Acceptable behavior in case of error
We are not in the beginning of informatics
in the place and in the time someone place the first stone to the home
for computers.
In a programming language,
in codegolf the only acceptable behavior on errors are:

So I just begin to learn Python, and solve some easy problems for practice. My code for this one is:
data = "0123456789+"
digits = [dat[7*i:7*i+7] for i in range(11)]
inp = sys.stdin.read()
inp = inp.split('\n') [0:7];
result = str(eval("".join([
data[
digits.index(
[ line[6*i:6*i+5] for line in inp ]
)
]
for i in range(len(inp[0]) // 6 + 1)
])));
print (
"\n".join([
".".join([
digits[data.index(ch)][i] for ch in result
])
for i in range(7)
])
)
Do you think the nested list comprehension is too obfuscated, and any code-review tips?

I'm a little unsure if I should edit this proposed challenge (my first challenge so far) and remove the requirement to determine "glass fullness", it kind of feels a little glued onto the challenge and just an extra random thing to do. Also, requiring to output long, fixed strings is bad. Shoud I remove it, change it, or leave it as it is? What's your opinion on that...?
Thou shall permute!
Given a string of upper and/or lower case letters and/or numbers (or list of characters if you want),
and a list of permutation cycles, compute every intermediate step of applying this permutation under the following rules:

@Pavel Washington is pretty great, I'll give you that. But Utah's incredible. The Redwood forest in Cali is amazing. (and the beaches in Cali). The Rockies, the plains, and the Sand dunes in Colorado are gorgeous. The grand canyon (and even smaller canyons) are breathtaking.
@DJMcMayhem I don't really appreciate looking at nature from a safe distance. I'd probably have enjoyed the grand canyon more if I could have climbed down into the canyon itself, but I didn't end up going anywhere it was remotely safe to do so.
That's why I like forests. You can climb whatever you want there.
@user202729 advent is defined roughly as the arrival of something/someone important; in this case, it's the 25 (or 24) day countdown to christmas. i'm going to try to post one advent challenge a day but I don't think I'll be able to :P

A friend of mine is asking if I know of a chat "where they discuss 'The X-ic way to do Y' like 'The Pythonic way to sort a list of objects' things like that"
Quoting again: "I mean, a lot of stuffs can be done using different paradigms: using for loop, for each, functions such as sort(), etc"
I figured we might, but do you guys know of any other chats like that?
Random developer appreciation: Discord is awesome. Not only is there dev team really funny and constantly improving discord, but the number of different things it supports always surprises me. Today I learned that if you share a spotify link in discord, it will onebox and connect to the instance of spotify you're running. You can play/pause from within discord
