Coding Conventions - Naming Enums
...re constants and should follow the conventions for constants. So
enum Fruit {APPLE, ORANGE, BANANA, PEAR};
There is no reason for writing FruitEnum any more than FruitClass. You are just wasting four (or five) characters that add no information.

What is a smart pointer and when should I use one?
...ue_ptr, std::shared_ptr and std::weak_ptr.
There was also std::auto_ptr. It was very much like a scoped pointer, except that it also had the "special" dangerous ability to be copied — which also unexpectedly transfers ownership.

Difference between numpy.array shape (R, 1) and (R,)
...turn (R,) . This will make matrix multiplication more tedious since explicit reshape is required. For example, given a matrix M , if we want to do numpy.dot(M[:,0], numpy.ones((1, R))) where R is the number of rows (of course, the same issue also occurs column-wise). We will get matrices ar...
How do I make my GUI behave well when Windows font scaling is greater than 100%
...inst assuming DPI-awareness is easy.
I generally avoid DPI-aware scaling with TForm.Scaled = True. DPI awareness is only important to me when it becomes important to customers who call me and are willing to pay for it. The technical reason behind that point of view is that DPI-awareness or not, y...
