Hack: Put your keys on your moneyclip

Things that are only sort of banned
Security guru Bruce Schneier has a post about something that had always bothered me but that I'd never been able to put my finger on. Basically there are some things that you can't take on a plane but that don't get you in any trouble if you get caught trying to take them on a plane.

Flash Game: Fantastic Contraption
Fantastic Contraption is a fun little game where on each level you have to move an object from a starting point to a goal. You do this by constructing a machine from various parts and then letting the machine do the actual moving.
After you have completed a level you can see what machines other people built to solve the same problem. Some of these are amazingly complex.

Fibonacci Converter
Futility Closet has a short post about how you can use the Fibonacci sequence to convert miles to kilometers.
This works because the two units stand in the golden ratio (to within 0.5 percent).

Obit: David Caminer the first systems analyst
The New York Times has the obituary of David Caminer. Caminer worked at Lyons which was a British tea shop chain. After losing a leg in the Second World War he returned to Lyons and became the manager of their systems analysis office. It was there that he helped implement the world's first commercial computer system.
The finished LEO, which had less than 100,000th the power of a current PC, could calculate an employee’s pay in 1.5 seconds, a job that took an experienced clerk eight minutes. Its success led Lyons to set up a computer subsidiary that later developed two more generations of LEO, the last with transistors, rather than the noisy vacuum tubes used in the first two models.

Monthly Smashing Wallpaper
Smashing Magazine have their monthly post of desktop wallpaper. I've gone with the shot of St Paul's Cathedral (mostly because that used to be the view out my window) but I do miss last month's levitating kung fu rabbit.

Factoid: Car Sales
Ford's venerable F150 pickup ended its 17-year-run as the best-selling vehicle in America last month, dethroned by the Honda Civic and three other Japanese sedans. General Motors is looking to unload Hummer, the epitome of gas-guzzling excess, after sales fell 60 percent in May. The number of Civics sold in one month exceed the number of Hummers GM expects to sell all year.From this interesting Wired post about how high gas prices have killed the SUV.

Weaving with Index Cards
This isn't origami but it is something sort of useful that you can do with an index card. Craft magazine has a video that shows how you can make a loom out of two index cards. Obviously this only works if you want to weave something the width of an index card.
