Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Installing Brew

The Mosquitto MQTT Server can be easily installed using Homebrew.  If it’s not installed on your system already, then a quick visit to the homepage will give you all you need to get going.  Homebrew is an OS X Package Manager for installing and updating non-Mac OS X utilities that are more commonly found in other variants of Linux.  To install the basic package manager run the following command.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

On a recent project, I ran into an issue with Python Selenium webdriver. There's no easy way to open a new tab, grab whatever you need and return to original window opener.

Here's a couple people who ran into the same complication:

• http://stackoverflow.com/questions/17547473/how-to-open-a-new-tab-using-selenium-webdriver
• http://stackoverflow.com/questions/6421988/webdriver-open-new-tab/9122450#9122450
• https://groups.google.com/forum/#!topic/selenium-users/kah4iEPRopc
• ... and many many more.

So, after many minutes (read about an hour) of searching, I decided to do find a quick solution to this problem.

-- 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:
