Making Bookmarklets

This is one chapter of my "Chrome Extension Workshops" tutorial, see the rest here: https://gist.github.com/caseywatts/8eec8ff974dee9f3b247

Unrelated update: my book is out! Debugging Your Brain is an applied psychology / self-help book

Making Bookmarklets

I'm feeling very clever. I've got this sweet line of javascript that replaces "cloud" with "butt". My mom would LOVE this, but she doesn't computer very well. I'm afraid to show her the Developer Console and have her type/paste this in. But she IS pretty good at bookmarks, she knows just how to click those!

A bookmark normally takes you to a new web page. A bookmarklet is a bookmark that runs javascript on the current page instead of taking you to a new page. To declare that it is a bookmarklet, the "location" it points to starts with javascript:.

Here is a little script that I wrote to manage capistrano deploys. It checks for asset changes and precompiles assets, if needed. It also looks for schema changes and will run migrations if there are any changes. It uses GitFlow for release creation.
#!/usr/bin/env ruby
require 'date'
require 'git'
class Releaser
attr_accessor :app_path, :repo, :skip_deploy, :version, :version_file
def initialize(app_path, version, version_file, skip_deploy=false)
raise ArgumentError.new('First argument must be version number in Major, Minor, Patch format, ex. 11.222.324') unless version.valid?

git pr - Global .gitconfig aliases for Pull Request Managment

Install

Either copy the aliases from the .gitconfig or run the commands in add-pr-alias.sh

Usage

Easily checkout local copies of pull requests from remotes:

  • git pr 4 - creates local branch pr/4 from the github upstream(if it exists) or origin remote and checks it out
  • git pr 4 someremote - creates local branch pr/4 from someremote remote and checks it out

Back in 1997, when I was a PC Support Specialist, I asked Frank Stuart, who was our systems administrator (and had already put in notice to leave), what things I'd need to know in order to "keep the wheels on" until we could find a systems administrator to replace him. He said, "no problem", and the next day emailed me the following list:
ARP/RARP
Apache
C
DNS / bind / nslookup/ resolver library
IP Addresses (class A, B, C, D) / subnetting (subnet mask)
IPC / pipes / shared memory / semaphores
IPv6
NFS
