When should I use UNSIGNED and SIGNED INT in MySQL?
... negative numbers (i.e., may have a negative sign).
Here's a table of the ranges of values each INTEGER type can store:
Source: http://dev.mysql.com/doc/refman/5.6/en/integer-types.html

Difference between Python's Generators and Iterators
....
For example, a generator such as:
def squares(start, stop):
for i in range(start, stop):
yield i * i
generator = squares(a, b)
or the equivalent generator expression (genexp)
generator = (i*i for i in range(a, b))
would take more code to build as a custom iterator:
class Squares(obj...
What's the difference between equal?, eql?, ===, and ==?

Password entropy is approximated easily. Using the full range of ascii characters (roughly 96 typeable characters) yields an entropy of 6.6 per character, which at 8 characters for a password is still too low (52.679 bits of entropy) for future security. But the good news is: long...
