Mac OS X LEMP Configuration

This Gist is a collection of configuration files that can be used to easily setup a Homebrew-based LEMP stack on Mac OS X.

Files in this repository are numbered and named for ordering purposes only. At the top of each file is a section of metadata that denote what component the file belongs to and the default name & location of the file. Feel free to implement it however you want.

Note: some configuration files have hard-coded paths to my user directory -- fix it for your setup

# Idempotent way to build a /etc/hosts file with Ansible using your Ansible hosts inventory for a source.
# Will include all hosts the playbook is run on.
# Inspired from http://xmeblog.blogspot.com/2013/06/ansible-dynamicaly-update-etchosts.html

Conventions:

Defining Eloquent model (will assume that DB table named is set as plural of class name and primary key named "id"):

class Shop extends Eloquent {}

Using custom table name

protected $table = 'my_shops';

Breaking into Web Development

I work as an analyst contractor, these days my roles are often a mixture of development and management. I have been asked by a countless number of people what they need to do to get the jobs I’m offered – and it’s simpler than most expect. The market for talented developers in the United Kingdom (and in many talent-lite communities around the world) is such that anyone who merely knows what they are doing has a very good chance of getting a job. Even a job contracting (which ordinarily has senior-level requirements).

To become a web developer with a good salary and employment expectations you need skills. Below I’ll provide a plan to get you towards the top of the largest market: PHP Web Development. Advanced knowledge of everything on this list would immediately make you one of the best, so just strive to have an exposure if not a comprehensive understanding (though the *starred points are essential). To learn these technologies you should use several in combination on on

Share Counts

I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.

If you want to roll up all of these into a single jQuery plugin check out Sharrre

Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.
