Boolean attributes can now be set by appending "which", "that" or "who" at the end:

Given there is a movie which is awesome
And there is a movie with the name "Sunshine" that is not a comedy
And there is a director who is popular

Instead of "and" you can now also use "but" and commas to join sentences:

Given there is a movie which is awesome, popular and successful but not science fiction
And there is a director with the income "500000" but with the account balance "-30000"

When you roll custom URLs with hacks like routing-filter, you can put a spec like this into spec/routing/routing_spec.rb:

Autocomplete input that accepts multiple entries in one field using jQuery and jQuery UI styling; a temporary workaround before built-in multi-value support.

validate_format_of can fail in odd ways with Shoulda; allow_value is the safer matcher for checking valid and invalid email formats.

rjb is a bridge software. It connects Ruby and Java.

Problem:

Keyboard layout reverting to US on (every) reboot

Cause:

I found the same problem, but only on my wife's account. I'd set her keyboard layout to UK through Gnome preferences and every time the US layout would reappear and be selected frustratingly.\
It turned out that on the gdm login screen her choice of keyboard layout in the discreet option bar at the bottom of the screen was set to US. That was then overriding the Gnome layout preference.

Solution:

Selecting the appropriate keyboard layout on the next login solved the...

the best damn presentation software a developer could ever love

Passing long text blocks to Cucumber steps keeps feature files readable while preserving full Markdown content for step definitions.

Use the attached initializer to do stuff like this

str = "abc"
str.imbue(:foo => 'foo value', :bar => 'bar value')
puts str.foo # 'foo value'
puts str.bar # 'bar value'

Paperclip secret changes can move attachment files to new locations and break existing paths. A semi-automatic migration preserves uploaded files when secrets were copied between projects.

Capybara can lose the HTTPS state when specs cross between secure and insecure Rails actions, causing request URLs to fall back to the wrong protocol.

The following counts all the lines in all *.rb files in the app directory. Run several of these commands to get a rough estimate of the LOC.

find app -name *.rb -exec wc {} \; | awk '{a+=$1;print a}' | tail -1

Show all sockets (Unix & TCP/UDP), both listening and established ones:
netstat -anp

To limit the output e.g. to listening TCP sockets:
netstat -anp | grep tcp | grep LISTEN
...
tcp 0 0 0.0.0.0:3000 0.0.0.0:* LISTEN 28683/server
...

This means: A tcp v4 socket listening on port 3000 on all IP adresses (0.0.0.0 is synonym to 'all interfaces on the machine').

The last column includes the PID, kill -9 28683 should exit the process and clean up the socket.

traits.js is a minimal, standards-compliant trait composition library for Javascript.

YARD 0.6 adds the ability to serve documentation for gems as well as the current project with yard server. Just like gem server in RubyGems, you can serve gem docs. The advantage to YARD’s server is that you don’t need to pre-generate the static docs (with a gem install) before running the server. If you installed your gem with --no-rdoc, YARD will just generate it on the fly!

The following Sass will do it:

hr
  color: #ddd
  background-color: #ddd
  border: none
  height: 1px

Ruport’s acts_as_reportable module provides support for using ActiveRecord for data collection. You can use it to get a Ruport::Data::Table from an ActiveRecord model. This cheatsheet covers the basic functionality of acts_as_reportable and some common use cases.

IN queries return rows in undefined order; ORDER BY FIELD() preserves a custom sequence for matching IDs.
