Why do python lists have pop() but not push()
...t on the top and "pushing" down. "Pushing" at the front makes no sense (at least not linguistically). And just to make things even more confusing, C++ uses "push_front" and "push_back".

Can't pickle when using multiprocessing Pool.map()
...ut I had no joy there. To be honest, I can't see what part (of my code, at least) could be recursing out of control, unless for some reason the code is pickling and unpickling in a loop, due to slight changes I made in order to make Steven's code OO'd?

Does the use of the “Async” suffix in a method name depend on whether the 'async' modifier is used?
...re both awaitable types, they represent some asynchronous operation. Or at least they should represent.
You should add suffix Async to a method which, in some cases (not necessarily all), doesn't return a value but rather returns a wrapper around an ongoing operation. That wrapper is usually a Task...

Checking for a dirty index or untracked files with Git
... (they would not be using the new options, since they did not exist (or at least were not used) at the time the script was written).
Unfortunately the ‘everyday’ Git commands are the ‘porcelain’ commands, so most Git users may not be familiar with with the plumbing commands. The distinction...

For posterity, or at least anyone getting here from a search, here are two versions of things -- the "I'm busy, so just the facts please" version and a more involved discussion and rationale. Both of these versions assume you are trying to build...

Calling C++ class methods via a function pointer
...ues are a reason for non-portability with member pointers - Visual C++, at least in the past, needed some extra clues about how to represent member pointer types. I'd use the static function approach for an embedded system - the representation of a pointer is the same as any other function pointer, ...
