Google URL Shortener Opened To the Public

dr. greenthumb Re:Too bad for case-sentive (244 comments)

It's about keyspace.

Given 4 bytes of [a-zA-Z0-9] gives you 14,776,336 possible combinations while [a-z0-9] only gives you a mere 1,679,616 possible combinations.
Assuming they'll eventually up the number of bytes up to six (ie. 4 to 6 bytes), you'll get 57,731,144,752 combinations case sensitive compared to just 2,238,928,128 case insensitive.

What Is the Oldest Code Written Still Running?
