Customize SSH tab name in Mac OS X terminal auto-magically.

What

Automtically configure tab name in Terminal.app when ssh-ing to a server. You can use any shell commands you want to get the desired output.

Why

I work on external servers 8 hours a day M-F and more likely than not I have multiple ssh sessions at the same time to the same sever under different users. It became a bit of a pain to have to rename the tabs everytime I logged on to a server. I just wanted that to happen auto-magically.

I searched the interwebs and came across this CNet article which had about 99% of what I was looking for. However, it never really mentioned how to modify the script to insert your own formatting. It didn't even mention adding it to your $PATH! So after a few minutes of messing with it I got something quite reasonable. I thought I'd share the results.

Add Bootstrap to your Rails app without a Gem

Bootstrap 3.0 in Rails without a Gem

What is Bootstrap?

It's a collection of CSS styles and Javascript add-ons that stop your site from looking like a shitty craigslist rip off from 1996. Seriously, who wants that?

Docs: CSS, Components, Javascript

Why Install It This Way?

Finding the right gem, keeping it updated, and learning the syntax is a pain in the ass. Why not install Bootstrap the way you'd install new javascript libraries?

Get Glyphicons up and running in Rails 3.2 without using a gem

Getting Glyphicons from Bootstrap 3.0 in Rails: the easy way

What

Bootstrap 3.0 gives you access to the awesome icon set icon set by these dudes but it's not obvious for a Rails newbie like myself to get it all working together nicely

How

  1. Download the bootstrap-glyphicons.css from here. Save that file to RAILS_ROOT/vendor/assets/stylesheet/bootstrap-glyphicons.css
  2. Save all the font files in /dist/fonts from the Bootstrap 3.0 download to a new folder in your Rails app RAILS_ROOT/vendor/assets/fonts
  3. Add this folder to the asset pipeline by appending config.assets.paths << Rails.root.join("vendor","assets", "fonts") to application.rb after the line that has class Application < Rails::Application.
  4. In bootstrap-glyphicons.css modify the the `url

Get Application Switcher (cmd + Tab) to show up in both displays in OS X Mavericks

Fix Cmd Tab / Application switcher in OS X10.9 Mavericks

What

OS X Mavericks has some some seriously awesome dual screen support (Mutha-Fuckin' finally, AMIRITE?) but there seems to be a bug if you have your docked pinned to either side of your display.

The Fix

Unfortunately, it means moving your dock :-(

Sad times my friends.

Print stacktrace without raising and Exception in Ruby and/or Rails

Print a stacktrace in Ruby or Rails without raising an exception

Why

You know what method is being and you want to figure out how it got there. Raising an exception is a bit harsh since all you want is a stack trace

How

puts caller

Seriously. It's that easy. If you're getting too much information you could
