I highly suspect that the RSpec core team all use black backgrounds in their terminals because sometimes the colors aren’t so nice on my white terminal

I certainly use a black background. I'm not sure about the other RSpec core folks. Regardless, if there are some color changes we can make that would make output look good on a larger variety of backgrounds, we'll certainly consider that (do you have some suggested changes?). In the meantime, the colors are configurable, so you can change the colors to fit your preferences on your machine. First, create a file at

# 1. Get the source however you like
wget http://ftp.ruby-lang.org/pub/ruby/2.1/ruby-2.1.1.tar.gz
tar xfz ruby-2.1.1.tar.gz
cd ruby-2.1.1

# 2. Apply this patch! This is the interesting part.
curl https://gist.githubusercontent.com/henrik/10880288/raw/fe228cf0524873c992fa5c31b1173537dca76a2c/patch.diff | patch -p0

# 3. Build it however you like
# config/routes.rb

Ruby 2.1.0 in Production: known bugs and patches
Last week, we upgraded the github.com rails app to ruby 2.1.0 in production.
While testing the new build for rollout, we ran into a number of bugs. Most of
these have been fixed on trunk already, but I've documented them below to help
anyone else who might be testing ruby 2.1 in production.
@naruse I think we should backport these patches to the ruby_2_1 branch and
release 2.1.1 sooner rather than later, as some of the bugs are quite critical.
I'm happy to offer any assistance I can to expedite this process.

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style
