How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

# The command finds the most recent tag that is reachable from a commit.
# If the tag points to the commit, then only the tag is shown.
# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object 
# and the abbreviated object name of the most recent commit.
git describe

# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
git describe --abbrev=0

Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

• http://mvdirona.com/jrh/talksandpapers/jamesrh_lisa.pdf

Basic tenets

• Does the design expect failures to happen regularly and handle them gracefully?
• Have we kept things as simple as possible?

# Setting up internet explorer machine with selenium

Download the machine with appropriate windows and IE from microsoft
https://www.modern.ie/en-us/virtualization-tools

Boot it up with GUI

Disable UAC and firewall - its an isolated machine that noone will access anyway(and if they do, theres really nothing there), so why bother

"""A simple demonstration of running background tasks with Tornado.

Here I am using a basic TCP server which handles streams and keeps
them open while asynchronously performing a fake task in the
background. In order to test it, simply telnet to localhost port 8080
and start typing things to see that the server receives the messages.

The advantage to running on an executor instead of conventional
threads is that we can more easily shut it down by stopping the
tornado IO loop.
