Photo Building

My friend Victoria is a photographer. I’m interested in photography too, and like to help her when I can. I noticed that she was researching styles of photography for autumnal, rustic, foods. One example in particular caught my eye. It caught my eye because it’s the sort of photography I like: a staged scene, that’s […]

Units of Measurement

I am generally all for not legislating anything, but the world really does need to use a commonly agreed system for physical measurements. That system is, like it or not, metric. Or rather SI units. I am sure I am not alone in thinking that some mistakes were made in the SI unit system — […]

Pushmepullyou: Discount for Cash

I’ve touched on the idea before, but I thought it was time I made it explicit. I want to compare customer-not-present purchases using bitcoins and using credit cards. In particular: security.

Bitcoin Explained (II)

This is part II in my “Bitcoin Explained” series. The problem we left at the end of part I was that the construction of a valid chain of payload-storing blocks is trivial (for a computer) to create. For a financial system we want it to not be trivial, we want it to be incredibly hard […]
