Created July 13, 2018 07:20 — forked from chrisboulton/ip_blacklist.lua
Redis based IP blacklist for Nginx (LUA)
-- a quick LUA access script for nginx to check IP addresses against an
-- `ip_blacklist` set in Redis, and if a match is found send a HTTP 403.
--
-- allows for a common blacklist to be shared between a bunch of nginx
-- web servers using a remote redis instance. lookups are cached for a
-- configurable period of time.
--
-- block an ip:
-- redis-cli SADD ip_blacklist 10.1.1.1
-- remove an ip:

Created August 21, 2018 06:36 — forked from derekconjar/wordpress-firebase.php
An example of using Firebase and WordPress together. The idea is to use WP's custom post types and metaboxes to make content management easy, and sync with Firebase so that your websites have access to a real-time JSON feed of your custom data.
<?php
/**
* All custom functions should be defined in this class
* and tied to WP hooks/filters w/in the constructor method
*/
class Custom_Functions {
// Custom metaboxes and fields configuration
