So it's just file access and not arbitrary system calls we have to worry about? That's still a problem (a malicious person could fill the hard drive with garbage), but not as worrysome.
@quartata Everybody can write to /tmp, and that can't realistically be prevented without sandboxing. Creating a file and executing it are pretty different though. If you can execute arbitrary code, you don't need to create a file.
Traceback (most recent call last):
File "/opt/V/main.py", line 74, in <module>
main()
File "/opt/V/main.py", line 41, in main
v_instance = v.V(args)
File "/opt/V/v.py", line 36, in __init__
self.nvim_instance.command("source nvim/safe_mode.vim")
File "/usr/local/lib/python2.7/dist-packages/neovim/api/nvim.py", line 201, in command
return self.request('vim_command', string, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/neovim/api/nvim.py", line 129, in request
res = self._session.request(name, *args, **kwargs)
So I am seeing that error where nvim fails to source the correct files, but I'm not sure why that's happening since I am exporting an environment variable.
The sandbox itself was working fine, but the sudo call created a clean environment which didn't contain the V variable. I don't know why, but V just hangs indefinitely in that case.
hey, I'm looking to write a more formal spec for Elegance. Anybody know of any languages that do it well (easy to read, while being specific and clear)?
is that a real problem ? :P what it literally mean(s|t) is somewhat irrelevant--as is the case with idioms etc. Taking it literally is rather antagonistic to the construct of language
I'm not saying it's a problem, just that there is no clear distinction between religious/non-religious terms. I say ojalá (hopefully) more frequently than adiós, which literally means may Allah will it.
Well, I haven't heard someone use beatitude in a non-religious context. But then again, I haven't heard anyone use it in a religious context, so that doesn't really prove anything.
I found some that are probably pro to your cause (found with online grep thingy)

This is a question about American English usage of the word "already". As a UK resident I don't completely understand when I hear Americans give commands like "Stop it already!" In the UK the word already is not normally used in the imperative mood and the sentence I've just quoted would leave an...
Also I think I've settled on approval voting as being the best system to use/promote. My initial concern was that it doesn't strictly obey the Condorcet Criterion, but apparently computer models indicate that it elects the Condorcet winner almost every single time. The main reason I see to use it instead of a full "ranked" system is that ranked systems open the door to "illogical strategic voting."
In which voters tend to dishonestly rank minor candidates they don't like above major candidates they don't like, in an attempt to hurt the major candidate, despite the fact that voting dishonestly in this way can only ever hurt the election outcome.
@NathanMerrill TL;DR I'm actually trying to do some political activism to promote better voting systems (given the current state of the American political system, I believe the population is receptive to change).
@NathanMerrill I'm not exactly sure what you mean by that.
Approval voting is "mark the candidates that you approve, candidate with highest percent approval wins." Since it allows voters to evaluate each candidate independently of the others, it fulfills "independence of irrelevant alternatives" (meaning no spoiler effect or vote splitting).
@PhiNotPi its a case where, in essence, the state had refused to redraw districts because that would put many of them out of office. (Thankfully/Horrifyingly, the supreme court deemed that they would redraw the lines)
and, while I definitely agree that a better system is in order, simply having the public on your side doesn't always mean that you'll get those in office to go along with it
Voter 1 approves of candidate X and Y (but slightly favors Y over X). Voter 2 approves of candidate X but disapproves of candidate Y (thus favors X over Y). Voter 3 disapproves of bot candidates X and Y (but hates Y less). Candidate X wins even though 2 of the 3 voters actually prefer Y over X.
In that way, it fails the Condorcet criterion. The good news is that voters don't act like that in real life.
@HelkaHomba Then you fail the independence of irrelevant alternatives criterion.
Meaning that the introduction of additional candidates alters to ordering of existing candidates.
Also, in a ranked system like that, you could have 5 districts that each declare candidate G the local winner, but combining the 5 results causes candidate K to win instead.
Prime Wednesdays
Your task is to count the number of Wednesdays that fall on a prime day of the month in a particular year. For instance, 7-13-16 is a prime Wednesday. For consistency use the Gregorian calendar for all dates.
Input
The input to your program/function will be a year (eg 2016) an...
CAPTCHA Modified by Evil Mathematician
I accidentally incurred the wrath of an eccentric passive-aggressive mathematician. As part of his demented idea of payback, he modified the CAPTCHA system on my favorite website. Up until now, it would just ask a moderately challenging math question, like ...
Most of those are also "fringe results" that only really arise in theory (aka, voters would basically have to cooperate to trick either approval voting or ranked voting in the methods listed above).
The main issue with ranked voting is a more psychological one: voters are much more likely to dishonestly rank a candidate than dishonestly approve a candidate. Consider the scenario in which voters want to "punish" the other major candidates by putting them at the bottom of their ranking list. This can lead to inaccurate results (sometimes nobody's major candidate wins, and some minor candidate everyone overlooked wins instead).
If I post a challenge that already exists, let it be. It's probably because the old challenge hasn't been active for a very long time and/or because I want to give other users a chance.
Everyone can still participate in the old challenge. Except in some special cases (cops and robbers, king of the hill, etc.), challenges are never over.

Question to everyone. Why is disallowing golf languages so badly recieved? All I want is a question that gets real answers, not someone winning within the first 5 minutes with their V, Jelly, 05AB1E, or J answer. I just want this site to have some real competition, not just a select few people winning.
