Question for the author. I have historically had low Vitamin D levels and recently had my thyroid removed due to thyroid cancer. Do I need to be particularly worried or do anything to supplement my vitamin D?
As this site is predominantly read by people with software development experience I think Rob Pike's rules of programming are apposite here: https://news.ycombinator.com/item?id=24135189
Specifically rules 1 and 2:
Rule 1. You can't tell where a program is going to spend its time. Bottlenecks occur in surprising places, so don't try to second guess and put in a speed hack until you've proven that's where the bottleneck is.
Rule 2. Measure. Don't tune for speed until you've measured, and even then don't unless one part of the code overwhelms the rest.
