Forked from: corbanb/gist:76d0658493e93830af48 which borrowed heavily from http://blog.shupp.org/2012/08/12/local-timezone-lookups-by-coordinates-with-postgis/ to make this geared towards mac users, which has been updated.

Step 1: Install Postgresql & Postgis + dependencies

$ psql -U <user> -d template_postgis  
$ template_postgis=> select postgis_lib_version(); should return installed version!  
$ template_postgis=> \d+tz_world

Hi, I'm Jon and I’m a freelance / contract Ruby / RoR developer based in Sydney;

I've been working with Ruby professionally for around 10 years, I consider myself a specialist in test driven development with Ruby, using Rails for customer facing sites (e.g. if it serves HTML). I'm one of the current maintainers of RSpec so as you can appreciate I'm a huge fan of using it for both unit and integration testing.

How can I help you? I have a lot of experience building prototype apps, polishing existing products, improving site performance, reviewing and improving code quality or improving test setups. Our work together could be a specific project or a time based contract. I typically work with the server side

Most active GitHub users (git.io/top)

The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at GitHub.com from Sat, 17 Nov 2012 22:58:25 GMT till Sun, 17 Nov 2013 22:58:25 GMT.

Only first 1000 GitHub users according to the count of followers are taken. This is because of limitations of GitHub search. Sorting algo in pseudocode:

githubUsers
 .filter((user) -> user.followers > 30)

Use contexts

Contexts are a powerful method to make your tests clear and well organized. In the long term this practice will keep tests easy to read.

I agree with the premise, and I agree that this:

BAD
it 'has 200 status code if logged in' do
