The Third Bit: Distributed Systems Design by Example

@gvwilson I've been following yours posts and I believe you achieved something pretty good already. I'll make sure to point anyone to it when recommending practical resources to learn any of those topics.

One minor thing, not sure if you are aware, the rendering of code blocks seems to have an issue on mobile. Either the long lines are not wrapped or the block isn't long enough.

@ederlm thanks - if you would like to PR a fix to the CSS in https://github.com/gvwilson/dsdx I'd be happy to merge it. (My CSS skills are very limited.)

@gvwilson Mine aren't great either, but I'd be happy to take a look when I get sometime this week :)
