A long, long time ago...
I can still remember
How his blog used to make me smile.
And I knew that if he had his chance
That he could make their code enhance
And, maybe, they’d be happy for a while.

But August made me shiver
With every code line I’d deliver.
Bad news on the doorstep;

This readme is a mixture of everything I read on SO+nokogiri wiki, which ultimately worked out for me.

Here are the steps which worked for me to get rid of segfaults with Nokogiri 1.4.4, on both Lion and Snow Leopard, with Ruby 1.8.7 (patchlevel 334 and +).

First diagnose which version of libxml2 you're using:

bundle exec nokogiri -v

If you have 2.7.3 listed somewhere, you're in bad waters (known to segfault). Install this:

Hello there fine madam or sir!

I have a short quiz for you. It won't take long.

By the way, don't worry if there are questions you can't answer. Lots of people will be struggling along with you, so don't feel bad. You're not alone.

Let's begin!

Do you recognize the method for which this is the (simplified) source?

#!/bin/sh

# Git Remove (from version control) any file that is covered by the ignore patterns and exists on the filesystem. Could be improved to further check the file exists on the git filesystem too.

for eachthing in `git ls-files --others --ignored --exclude-standard`; do if [ -e "$eachthing" ]; then git rm $eachthing; fi; done

Emoji Spec

Tired of the same, dull rspec output? liven it up with some emoji!

Below are the sets presently available, and their corresponding id. if you don't set an ID, one will be randomly chosen every run. Emoji icons may not render in certain terminals.

f = -> x { x + 2 }
g = -> x { x * 2 }

# h is the composition of f and g
h = f >> g
# h is the same as -> x { (x + 2) * 2 }

[1, 2, 3].map(&h) # => [6, 8, 10]
# This is exactly the same as
[1, 2, 3].map(&f).map(&g) # => [6, 8, 10]
