I have been tearing my hair out at work for the last day trying to resolve an issue with a web application that uses SignalR over WebSockets where traffic is directed through a Barracuda Web Application Firewall (WAF).

I’m going to tell you why you should care about your history and how you can tell a story with it.
Both of these commands enable you to achieve the same end goal, but they both achieve this in different ways.

So I finally decided to try my hand at blogging and decided to see how easy it was to use Github Pages, Powered by Jekyll.
