Trusting Inputs, Via RESTa Via Nanciacum

All too often, security is treated as an afterthought in our models. I’m as guilty of this as anyone. :) Now that HTTP is becoming the most popular protocol inside the enterprise, sending bad data across the wire becomes much easier.

I’ve been taking a bit of a coding vacation. Before I jump back into things, I decided to do a little housekeeping and clean the cobwebs from my interwebs.

The fastest information can ever travel is 3*10^8 m/s - in a vacuum. It’s 2/3rds that in a copper wire. In the ideal case. Imagine two observers in the milky way galaxy, one at Terminus and the other at Star’s End. They will observe events from all over the universe at different times - they will not agree on the order of events. What they can agree on is that eventually they will see all of them.

Anyway, my suspicions were confirmed: This is actually from the IE debugging tools but you get the idea.
