Leap Second on 6/30/2015 Caused mysqld Process To Consume CPU

This morning I got a notification that mysqld was consuming on average 35% of the CPU on one my servers. This was strange because this particular server doesn’t even use MySQL regularly.

Datatables in a Colorbox iframe with Selected Row Returned to Parent Window

I recently created a form where one of the questions was asking for a specific code (specifically, a NAICS code). The problem was that there are almost 20,000 codes to choose from, so it was not practical to use a pulldown. I hit upon the idea of using the wonderful Datatables table plugin for jQuery. […]

Suppress Test::More Output For Use In Nagios

I needed a quick way to check for XML well-formedness in a Perl Nagios script and I found that Test::XML has a test called is_well_formed_xml($xml) that does the job nicely.

Find a Javascript parent node that matches a certain string

Here’s a small bit of javascript that I use in my Sencha Touch projects to find a parent with an id that matches a string. function findParentNodeRegex(regex, childObj) { var testObj = childObj; var count = 1; while(!testObj.id.match(regex)) { //console.log(‘My name is ‘ + testObj.id + ‘.

Detecting a click in a checkbox with jQuery

A simple script to detect when a checkbox is clicked. What you do with once you’ve detected the click is up to you. <html> <head> <script src=”http://www.google.com/jsapi”></script> <script> google.load(“jquery”, “1.3.2”); google.setOnLoadCallback(function() { $(‘#agree’).click( function() { if($(this).attr(‘checked’)){ alert(‘checked’); } else{ alert(‘unchecked’); } }); }); </script> </head> <body> <p> <input id=”agree” type=”checkbox” /> I agree </p> </body></html>
