The way this question is currently phrased is not quite a perfect fit for CodeReview but I believe that changing the phrasing to this question a bit would make it a better candidate for CodeReview than here. — Dair 42 secs ago

@DerKommissar Eventually, but that set costs more than my monitor did.
Looks interesting though.
Not feasible, since I'd need one for both myself and work and work isn't going to spring for it, but definitely interesting.
If your code works well and there is no issue, please consider posting the question at Code Review. — Wiktor Stribiżew 11 secs ago

Can you share a link with more details, that may be interesting for the ones reading this. However to my understanding .gitignore can help you to keep files from being added to source control, however it does not prohibits code do be hard-coded into your source. This however can be mitigated using source code analysis and code review — papanito 9 secs ago

@JAD I mean it's not the answer, but it's definitely making things a little better.
@Mast Same. For me, the ergonomics of my back not hurting as much are worth it.
Either spend $40 / week on a chiropractor, or $354 once on a keyboard that helps a lot, with as much as I type.
@DerKommissar I thought you might be spending that money for your back.
Honestly, at this point, my back is so bad it's almost unnoticeable anymore.
@DerKommissar Have you had a "Slipped Disc" or other disc problem yet? I had one in the "C" region of my spine that caused me to limp for 2 years.

@DerKommissar Never needed a chiropractor, but I imagine the stakes change once one gets involved.
@dfhwze @pacmaninbw FYI it should be knocked out of the review queue now.
Looking for 1 more VTC here, lacking context. Code is too far turned into hypothetical.

Extremely hard to discuss a refactor if there are no implementation details given. What do the calculations look like? Do they share similar elements? Bring this question up at Code Review and be sure to add more details. Refactoring usually involves stripping out duplicative logic and good/better namespacing/object oriented approaches. — Andrew 27 secs ago
