Last active August 29, 2015 14:21
Quick way to filter/remove non-truthy (null, empty string, number 0, NaN, boolean false) values from an array in Javascript.
['false', '', false, true, '0', 0, null, NaN, 1, '1'].filter(Boolean);
// => ["false", true, "0", 1, "1"]

codfish / cast_to_integer.js
Last active August 29, 2015 14:21
JS tip to cast to an Integer, avoiding any NaN pitfalls. "Something to watch out with this approach is for the number to lie within the boundaries of a signed 32-bit integer (or from -2147483648 to 2147483647, inclusively.) Otherwise use your usual Math.floor(). This limitation stems from the fact that we're technically doing a bitwise operation…
// It will always return an integer (never NaN) and will set v to 0 if it was not a number.

v = ~~v;

codfish / xdebug_no_limits.php
Last active August 29, 2015 14:20
Removes limits on xdebug variable output. If xdebug is installed these settings also affect native php functions like `var_dump`
<?php
// @see http://xdebug.org/docs/all_settings
ini_set('xdebug.var_display_max_depth', -1);
ini_set('xdebug.var_display_max_children', -1);
ini_set('xdebug.var_display_max_data', -1);

codfish / jquery-animated-scroll.js
Last active August 29, 2015 14:16
Simple jQuery snippet for a "scroll to" animation. Nice replacement for anchor links, rather than abruptly jumping to that spot on the page, this will scroll the page nicely to the desired anchor.
/**
* jQuery animated scroll to
*
* @example
* <a class="animated-scroll" data-target=".elem-selector-scroll-to" data-offset="60">Go to top</a>
*
* @param {data-target} the jquery selector of the dom element you want to scroll to
* @param {data-offset} how far from the top of the window you want the element to be (in pixels). Default is 20px.
*/
$(document).on('click', '.animated-scroll', function(e) {

Clean out everything in your current working directory, without deleting directory. You can do this with `rm` easily but this way is nicer imo
find . -delete
