UnicodeEncodeError: 'latin-1' codec can't encode character
...Code page 1252 is often confused with ISO-8859-1, and it's an annoying but now-standard web browser behaviour that if you serve your pages as ISO-8859-1, the browser will treat them as cp1252 instead. However, they really are two distinct encodings:

Difference between std::result_of and decltype
...f a deduction failure. That has been corrected in C++14: std::result_of is now required to be SFINAE-friendly (thanks to this paper).
So on a conforming C++14 compiler, std::result_of_t<F(Args...)> is strictly superior. It's clearer, shorter, and correctly† supports more Fs‡ .

Disable cache for some images
...to prevent caching was:
Cache-Control = 'no-store'
For completeness i'm now using all 3 of 'no-cache, no-store, must-revalidate'

What are bitwise shift (bit-shift) operators and how do they work?
..., you would use the following math:
memoryOffset = (row * 320) + column
Now, back in that day and age, speed was critical, so we would use bitshifts to do this operation.
However, 320 is not a power of two, so to get around this we have to find out what is a power of two that added together make...
