Benefits of prototypal inheritance over classical?
So I finally stopped dragging my feet all these years and decided to learn JavaScript "properly". One of the most head-scratching elements of the languages design is it's implementation of inheritance. Having experience in Ruby, I was really happy to see closures and dynamic typing; but for the li...
“Large data” work flows using pandas
...wer to this question for many months while learning pandas. I use SAS for my day-to-day work and it is great for it's out-of-core support. However, SAS is horrible as a piece of software for numerous other reasons.

... Great solution - I set the li 'line height' to be the same as my min-height, and the text is vertically aligned - at least close enough for a visual inspection. The 'table' solution above is certainly not semantic, and is hackish in nature. Any time we are doing that, we are increasing ...
typedef struct vs struct definitions [duplicate]

typedef int my_int;
my_int is a new name for int; my_int and int are exactly the same type. Similarly, given the struct definition above, you can write:
