The best number on Google Voice
I got a GV invite today and had to choose which number I want. Of course all the repeated digits are gone (215-777-7772, ...) are gone. Google provides a simple interface to find a good number, but this is the interface I like, grep: ===So I did the following (Mac 10.5 / Safari)=== 1. Download all available Google Voice phone numbers for a given area code. 2. Normalize the data: grep -ho +1484....... *js | sort -u | cut -c 3- > numbers 3. Grep through to find the best numbers available (some example results shown): # repetition grep "\([0-9]\{4\}\).*\1" numbers >> 4843248432 #pairs grep "\([0-9]\)\1.*\([0-9]\)\2.*\([0-9]\)\3" numbers >> 4842220022 >> 4842220044 # repetition grep '\([0-9]\)\1\{3\}' numbers >> 4849388886 # only 3 digits (mostly) grep '^[483]\+.$' numbers >> 4843344881 # palindromes grep "\([0-9]\)\([0-9]\)\([0-9]\)\([0-9]\).?\4\3\2\1"...
