In this article I'm going to walk you through process of creating Wordpress plugins. First I'm going to talk about some of the basic concepts in Wordpress plugin development like the actions, hooks, and API's that makes up Wordpress. Then were going to build a plugin where we apply some of the concepts and best practices in developing Wordpress plugins.

###Prerequisites

In order to fully benefit from this tutorial you should have a basic knowledge on PHP. As Wordpress is running on PHP and most of the code that we will be writing will be on PHP. A little bit of knowledge on HTML, CSS and JavaScript is also helpful but not required for this tutorial.

Format the drive

Restart with Cmd-R or Cmd-D
Erase drive / 3x if second-hand
Reinstall MacOS

Note: Some of these shortcuts have been remapped for my own convenience (Preferences->Keymap). These are Mac shortcuts, just use the Windows/Linux equivalent of the Cmd/Option/Ctrl/Del keys.

####Search, Go to, Navigation ####

Cmd + P - Search file

Cmd + Shift + O - Search everywhere

(I swapped the above two recently because I use Cmd + P to search for files most of the time).

Nginx FastCGI response buffer sizes

By default when Nginx starts receiving a response from a FastCGI backend (such as PHP-FPM) it will buffer the response in memory before delivering it to the client. Any response larger than the set buffer size is saved to a temporary file on disk.

This process is outlined at the Nginx ngx_http_fastcgi_module page manual page.
