Add a personal .gitignore to a project.

Within the project git config --local -e

[core]
    ... (existing configurations)
    excludesfile = ~/Documents/my_repo/.john_gitignore

Log Before Timeout

Logs a timeout warning before unicorn kills the worker.

If something is running long enough for unicorn to want to kill it then its worth spending the time fixing. If the process is killed you will never know why it failed.

This will add a warning after 30 seconds and another one 1second before unicorn kills it.

How it works:

It adds a middleware that sits on the Rack layer between Unicorn and Rails. It creates a timer Thread that sleeps for a set amount of time and if the current thread is still running then log a warning.

Transfer Homebrew Packages

I want to install my homebrew packages on another computer.

brew leaves - shows you all top-level packages.

brew leaves > installed_homebrew_packages.txt

cat installed_homebrew_packages.txt | xargs brew install

Browserstack

My setup for configuring a Rails app with RSpec Feature tests that uses Capabara to test on a browserstack remote browser.

The browserstack docs only show either an RSpec or a Capabara setup.

What I wanted:

In development run my tests quickly with poltergiest.
Run nightly builds on CI to test against different web browsers using browserstack.
Have the option to visually run my tests with selenium with Chrome, Firefox etc.
