MattSurabian / ArrayUniqueAlternative.php
Created May 5, 2013 19:56
A gist demonstrating a faster method to unique arrays in PHP. Embeded on my blog: http://mattsurabian.github.io/PHP/a-better-way-to-unique-arrays-in-php/
// array_unique is WAY TOO SLOW! This method is significantly faster.
array_flip(array_flip($arr));
// If you need new keys generated use array_keys
array_keys(array_flip($arr));

MattSurabian / MultipleInputOptions.php
Created May 5, 2013 20:39
The method I use when validating multiple input options in class setters. Embeded in my blog post http://mattsurabian.github.io/PHP/validating-multiple-input-options-in-php
if (!in_array(strtolower($input), array('always', 'hourly', 'daily', 'weekly', 'monthly', 'yearly', 'never'))){
return false;
//or throw an exception
}

FilibusterJS: The unfortunately life like filibuster simulator.
var issue = 'solve this mess';

MattSurabian / PackerPolicy.json
Last active May 27, 2022 21:46
Minimum IAM policy required by AWS for Packer to do its thing. https://github.com/mitchellh/packer Permissions are broken out by API functionality and a resource array has been defined with a wild card for each group. For tighter security resource level permissions can be applied per this documentation: http://aws.typepad.com/aws/2013/07/resourc…
