Monitor a URL for HTTP 500 errors using a crude shell script.
#!/usr/bin/env bash
#
# Takes a URL as an argument. Will test that URL every X seconds for a
# 500 response code. If a 500 is returned, this script will ring the
# terminal's bell and print a message.
#
# Ref: http://beerpla.net/2010/06/10/how-to-display-just-the-http-response-code-in-cli-curl/
#
# Usage: ./monitor-500.sh "http://yoursite.com/your/page.html"

Shut down VM network bridges on a Mac
#!/usr/bin/env bash
#
# If you're like me and have to switch between VMware Fusion and
# VirtualBox virtual machines on your Mac frequently, then you've
# probably run into one of the associated errors in this gist
# (https://gist.github.com/beporter/2841de37edbcc48a8755), particularly
# if you're using vagrant. This script shuts down or removes the bridge
# interfaces from BOTH providers so that they can start up cleanly again
# without conflicting with each other and without having to reboot your
# Mac.

History of the Synergy Project's "Bug #18 - Sticky modifier/meta keys (shift, ctrl, alt)" (now #9)

This is a crude list of stuff the Synergy team has chosen to focus on instead of an extremely old (and still unsolved) bug.

Provides a pre-composer mechanism for setting up a copy of the CakePHP core project in a local directory and then symlinking it into a target Cake project path.

CakePHP Core Setup

These scripts automate the process of obtaining a copy of the CakePHP core at a specific point release, the latest point release for a minor version, or a specific commit. They also provide a way to symlink the Cake core into an existing Cake project, which is handy for keeping all of the core files out of your project repo.

Usage

  • Place add-cakephp-version.sh in a folder of its own.

  • Run ./add-cakephp-version.sh x.y[.z] (where x is a major version number, y is a minor version number and z is an optional point release) to clone the CakePHP official git repository and set up a folder named cake_x.y.z in the same folder as the script.

Convert an integer byte value into a human-readable file size.
<?php
//----------
// Only works with INTEGER values for $bytes.
function human_filesize($bytes, $decimals = 2) {
$sz = 'BKMGTP';
$bytes = (int)$bytes; // This process only works with integer $byte values.
$factor = floor((strlen($bytes) - 1) / 3); // Determine the correct range.
$s = $bytes / pow(1024, $factor); // Knock out the right number of exponents.
$s = sprintf("%.{$decimals}f", $s) + 0; // Clean up decimals, `+0` removes trailing zeroes.
