Use ruby’s array sort() method, or add items in correct place with a binary lookup?
If I am loading a whole load of items (un-ordered words from a file or something) would it be more efficient to load them all to a Ruby array, and then use the built in sort! method or to do a binary lookup for the place of each item in the list as I load it, and add it in that position.

Heuristic for consistiently ordering points in a a plane
I have rectangular regions in a plane. I want to consistently order them in a human-friendly way that a typical y-x sort won’t work for. Basically I want (0,0), (1,0), and (0,1) to sort the same as (0,0), (1, -0.1), and (-0.1, 1).

Optimizing Sorting and Order Management in CoreData
Sorting is an important feature in my app. I am using integers to represent the ordering sequence.
Efficiently sorting 2D grid with only local operations
Suppose you have a n x m grid, and a pointer starting at (0,0), and the only operations you can do to the array, are:
