# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
# CREATE block and create them in separate commands _after_ all the INSERTs.

# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
# The mysqldump file is traversed only once.

# Usage: $ ./mysql2sqlite mysqldump-opts db-name | sqlite3 database.sqlite
# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite

Implementation of the Luhn 10 algorithm to check validity of credit card numbers. See http://en.wikipedia.org/wiki/Luhn_algorithm for details on the algorithm.

var validCreditCard = function(a,b,c,d,e){for(d=+a[b=a.length-1],e=0;b--;)c=+a[b],d+=++e%2?2*c%10+(c>4):c;return!(d%10)};

validCreditCard('378282246310005'); //=> true
validCreditCard('378282246310006'); //=> false

// some numbers to test with
// 378282246310005 371449635398431 378734493671000

Fenced code blocks inside ordered and unordered lists

1. This is a numbered list.

2. I'm going to include a fenced code block as part of this bullet:

# For mouse support (for switching panes and windows)
# Only needed if you are using Terminal.app (iTerm has mouse support)
Install http://www.culater.net/software/SIMBL/SIMBL.php
Then install https://bitheap.org/mouseterm/
