There are a lot of things that I don't know in Computer Science but if there was a King of Things I Don't Know, it would be "binary stuff". I was so scared of this topic that I avoided it completely with the first Imposter's Handbook.
You're about to see why. This is stuff (to me, at least) is simplistically mind-bending! I understand how to add and how to carry numbers - and it makes sense that you should be able to translate that directly to binary... and you can!
And then... things get a bit more difficult. I did my best with this video to make things as clear and simple as I could - I hope you enjoy.
I'm a big fan of testing, but I get lazy sometimes and it ends up costing me money, directly.
TDD is one of those things that people talk about, argue about, and think is interesting. I'm one of those people, so I asked Brad Wilson to clear it all up for me.
