  • The silk road wasn’t taken down by an acronym. It was a bunch of hypocritical bigots called the American bureaucracy. They talk a lot about freedom but when they see something that promotes freedom like Wikileaks, south American socialism or the silk road, they seek to shut it down, often violently.

    The people who believe that war criminals such as George Bush and Dick Cheney should be walking free and people like Julian Assange and Ross Ulbricht should be locked up, these people are our enemy.




  • Sadly, you are speaking for a great many places. I’ve cycled in most of the countries I’ve visited and it can be relatively dangerous.

    If people want to see how to integrate a public transport network with a cycle path network, places like Netherlands and Denmark are leading the way.

    Over here in the UK we have one of the most regressive attitudes to sustainable transport in Europe. Our trains don’t work and cycling is barely tolerated.















  • It’s a measurement on an arbitrary scale. Nothing I’ve said is news to anyone who designs safety critical systems. I’m certainly not saying that safety isn’t important or that we can’t assess it. What I’m saying is that placing a number on that assessment will always stray into the realm of politics in a way that physics and mathematics never does. It lulls ignorant people into the belief that something is safe or not safe. They feel safe because they’ve been told it is safe or vice versa. Physics doesn’t care if you feel safe.

    It’s notable that contemporary safety standards such as ISO 26262 generally avoid numerical assessments, for the reasons outlined above.



  • Safety cannot be measured because it’s a feeling. One person feels safe climbing a mountain without a rope and the next person is petrified. Safety is just word to describe a concept. It’s different to the wavelength of light or force or charge. These things are based on fundamental properties of the universe that can be measured and are repeatable.

    A reasonable approximation might be to consider the likelihood of an adverse event given a use case over time. We could say that an accident every million hours is our definition of safe but that is completely arbitrary in the way that the physical laws and constants are not.
