How Google determines which ad to display in a slot and how much to charge the advertiser:
Everyone knows the story of Clifford Stoll and and West-German KGB hackers (see the video below) in the late 80s. Does this history teach us something today? What strikes me as I watch this documentary again is the effort ratio between attackers and defenders. To fight a small adversary group, Stoll invested considerable effort, and from some point involved further people and organizations in the hunt. In effect, once they had been detected, the attackers were on their way to being overpowered and apprehended.
Today, we take more organized approaches to security management and incident response. However, at the same time we try to become more efficient: we want to believe in automated mechanisms like data leakage prevention and policy enforcement. But these mechanisms work on abstractions – they are less complicated than actual attacks. We also want to believe in preventive security design, but soon find ourselves engaged in an eternal arms race as our designs never fully anticipate how attackers adapt. Can procedures and programs be smart enough to fend off intelligent attackers, or does it still take simply more brains on the defender’s than on the attacker’s part to win?
A few weeks ago we saw the russian way of obtaining soda from a vending machine. It was simple and robust. French nerds employ an entirely different style:
This video shows a gang of street robbers at work in Bogotá. The commentary is in Spanish, but you’ll probably get some of the interesting point from mere watching: how they change clothes, how one of them picks a victim and indicates the pick to others, or how they literally overpower their target.
From an Australian campaign against mandatory bicycle helmet laws:
They picked a perfect analogy. Here in Germany, the number of people drowning and the number of people dying in bicycle accidents, repsectively, has the same order of magnitude: a few hundred a year. Both cycling and being around water are everyday activities for most of us, and the overall risk remains pretty low. Yet in one case we frequently discuss the need for protective gear as if it were particularly dangerous, while in the other, we just shrug it off—if the matter comes to our attention at all.
