Q: Reliable separation of Steam users

RickI wrote this bash script to try to make sure save games don't get mixed between different steam users using the same Ubuntu account. It uses inotify to try to figure out when a user changes and a soft link to point to the correct folder. #!/bin/bash link_name=~/.factorio check_username=$(awk -F'"...

Q: C++ Minimal CSV parser

Yes, some people do that. No, it is not good style. There are ways that you could simplify your makefile and make it easier to maintain without removing the filenames altogether, and that would be a better goal. Any way around, however, the question is too broad for SO. But if the makefile presently works as-is, then you could consider asking for improvement suggestions over at CodeReview SE. — John Bollinger 17 secs ago
Before you post at Code Review, make sure to read A guide to Code Review for Stack Overflow users, as some things are done differently over there - e.g. question titles should simply say what the code does, as the question is always, "How can I improve this?". Be sure that the code works correctly; include your unit tests if possible. You'll likely get some suggestions on making it more efficient, easier to read, and better tested. — Toby Speight 24 secs ago

For properly working code that needs improvement on style/performance, look at posting this on the sister side Code Review. It is another site on the stack exchange network that is more properly suited for questions like this. — blackbrandt 52 secs ago

This seems a better fit for codereview.stackexchange.com since your code works as intended — Juan Mendes 13 secs ago
Your question has nothing to do with a switch statement, it wouldn't improve your code at all? As I mentioned in my previous comment, if your code works as intended, stack overflow is probably not the best place for this question. You're asking for a code review — Juan Mendes 56 secs ago

Q: This code replaces each element of an array with the product of every element of the array except the current one. Suggestions for improvement?

It seems that your code currently works, and you are looking to improve it. Generally these questions are too opinionated for this site, but you might find better luck at CodeReview.SE. Remember to read their requirements as they are a bit more strict than this site. — gunr2171 30 secs ago
