XSD: What is the difference between xs:integer and xs:int?
...e Turing machines and stuff) should accept and properly represent the full range? :-) That would be cool, because the universe, with the laws of physics as they are currently known, does not admit such machines.

A simple explanation of Naive Bayes Classification
... say that we have data on 1000 pieces of fruit. They happen to be Banana, Orange or some Other Fruit.
We know 3 characteristics about each fruit:
Whether it is Long
Whether it is Sweet and
If its color is Yellow.
This is our 'training set.' We will use this to predict the type of any new fruit ...
In Ruby on Rails, what's the difference between DateTime, Timestamp, Time and Date?
... is a bit more subtle: DATETIME is formatted as YYYY-MM-DD HH:MM:SS. Valid ranges go from the year 1000 to the year 9999 (and everything in between. While TIMESTAMP looks similar when you fetch it from the database, it's really a just a front for a unix timestamp. Its valid range goes from 1970 to 2...
STL or Qt containers?
...on't), so reverse iteration is needlessly complicated.
STL containers have range-insert() from different, but compatible, iterator types, making std::copy() much less often needed.
STL containers have an Allocator template argument, making custom memory management trivial (typedef required), compare...
When is assembly faster than C?
... predict precision loss). i.e. uniform absolute precision over the entire range, instead of close-to-uniform relative precision (float).
Modern compilers optimize this fixed-point example nicely, so for more modern examples that still need compiler-specific code, see

Reverse a string in Python
... decrementing the index, although perhaps this is less readable: for i in range(len(a_string)-1, -1, -1): . Most of all I love that the example string you've chosen is the one case where you would never need to reverse it, and wouldn't be able to tell if you had :)

AngularJS: Is there any way to determine which fields are making a form invalid?

What MySQL data type should be used for Latitude/Longitude with 8 decimal places?
...o be absolutely sure of 8d.p. precision you should use DECIMAL.
Latitudes range from -90 to +90 (degrees), so DECIMAL(10, 8) is ok for that, but longitudes range from -180 to +180 (degrees) so you need DECIMAL(11, 8). The first number is the total number of digits stored, and the second is the numb...
