With standard symbol to proc, &:foo evaluates to:
{ |x| x.foo }
With the "pretzel bun", &foo&:bar evaluates to:

Thoughtbot retracted their initial implementation of strong parameters matchers in v2.0.0 of shoulda-matchers, so we decided to build our own until new official ones are released. The following is a small matcher for testing what params should be permitted in controllers. The matcher's syntax is based on validation matchers. If you're not follow…
# assuming your subject is the UsersController with a method user_params
describe UsersController do
describe "params" do
# per default the matcher extracts the subject and params method
it { should permit_params(:email, :name, :role) }
# to overwrite the params method use explicit .params_method()
it { should permit_params(:first_name, :last_name).params_method(:other_user_params) }

Ever committed with `gem 'foobar', path: '~/source'` in your Gemfile and broken a build?This git pre-commit hook ensures you never will again.If you try and commit while a gem in your Gemfile is loading with the `:path` option, you will be stopped with a helpful message. The only exception: gems embedded within your project are allowed.
#!/usr/bin/env ruby
# A pre-commit hook script to ensure that no local gem dependencies (gem 'asdf', path: '~/local')
# exist in your Gemfile before commiting.`
# Allows gems to be loaded from source within the current project directory, but not from outside.
puts 'Checking for local dependencies in your Gemfile.'

Install openproject plugins using the debian package

Let's say you wanted to install this plugin: https://github.com/finnlabs/openproject-meeting. Here is how you would do it with the openproject version packaged at https://pkgr.io/apps/tessi/openproject:

cat >> /opt/openproject/Gemfile.plugins <<EOF
gem "openproject-plugins", :git => "https://github.com/opf/openproject-plugins.git", :branch => "stable"
gem "openproject-meeting", :git => "https://github.com/finnlabs/openproject-meeting.git", :branch => "stable"
EOF

Upgrade Postgresql from 9.2 to 9.6 on an uberspace


Uberspace (an awesome german web hoster) has superb postgresql support, except that it currently only offers postgresql versions 9.2.x and 9.3.x. I run postgresql 9.6.2 on my uberspace and documented steps for a migration to postgresql 9.6 here.


My goal was to be as close to the original uberspace-postgresql-setup as possible, but I had to copy and modify some uberspace scripts so they correctly use the new postgresql version.


Warning: Here be dragons. This is what I did -- that doesn't mean you should do the same or what I did was clever. Always backup your data and maybe test on a throw-away uberspace first. If you find things to improve, let me know and I'll try to keep this updated.

Mac OS X 10.10 Yosemite


Custom recipe to get OS X 10.10 Yosemite running from scratch, setup applications and developer environment. I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install. On average, I reinstall each computer from scratch every 6 months, and I do not perform upgrades between distros.


This keeps the system performing at top speeds, clean of trojans, spyware, and ensures that I maintain good organizational practices for my content and backups. I highly recommend this.
