Brave New World

But liberty, as we all know, cannot flourish in a country that is permanently on a war footing, or even a near war footing. Permanent crisis justifies permanent control of everything and everybody by the agencies of the central government.

RegEx's

Why in god's name can I never remember even simple RegEx syntax. I use them every day, but I still have the following written down on a piece of paper by my side:

Character Classes

• \d - digit
• \D - non-digit
• \w - word [a-zA-Z0-9_]
• \W - non-word
• \s - whitespace [ \f\n\r\t\v]
• \S - non-whitespace

Quantifiers

• ? - 0 or 1
• * - 0 or more
• + - 1 or more
• {n} - exactly n
• {n,} - n or more
• {n,m} - atleast n, no more than m

I suppose this just goes to show that RegEx's were designed by a higher power, and were never designed for mortals.
