This year’s series is called The Triumph Of Technology
Four thousand years ago, just 5 miles north of present day Thetford, our Neolithic ancestors began what may have been the largest early industrial process in these islands. This is the site that the Anglo-Saxons called ‘Grimes Graves’ and it contains nearly four hundred mine-shafts, built to extract high-quality flints, which could be chipped to produce sharp cutting edges. Using nothing but tools of bone and wood and presumably the flints themselves, these ancient people excavated to a depth of up to twelve metres, to reach the buried flints. It has been calculated that the miners needed to remove 1000 tonnes of waste to produce eight tonnes of flint. The site covers nearly 40 hectares and the whole project is astonishing.
Whilst more advanced technologies had developed elsewhere – for instance in China – our ancestors’ task was anything but easy. They needed timbers to shore up their excavations and ladders to get down in to them, lighting was required in the deeper pits and they needed tools, which they made from deer antlers, so they had to manage the local herds of red-deer. A separate and skilled industry was required to work the extracted flints and to market and distribute them. The flints were used as axe heads, as agricultural implements, as arrow-heads, and no doubt there were countless other applications that we have lost track of. The Grimes Graves operation underpinned the foundations of a new sort of society. The timescale was quite different from our own. Excavation at Grime’s Graves lasted more than five centuries, whereas, for example, valve electronics lasted about fifty years.

By Lawrence Lessig June 2005
We entered the youth camp that morning by passing down a long, white gravel road and under a wooden gate. Spread to one side, and for as far as you could see, were rows and rows of tents. In front were scores of showers, with hundreds of kids in swimsuits milling about, waiting to rinse. It felt like a refugee camp.
In a sense, it was. More than a hundred thousand had descended upon Porto Alegre, Brazil, to attend the World Social Forum, a conference intended to offer a progressive alternative to the much smaller, and much more famous, World Economic Forum meeting at Davos, Switzerland (see “Letter from Davos,” April 2005).
Just past the showers was a sprawling collection of wooden huts, connected by a canvas spread across their roofs. This was the free-software lab. To the right, there was a training room, with more than 50 PCs arranged along long tables. At the far end was a large screen, where 20 to 30 kids were watching an instructor explain the workings of some video-editing software. Every machine was running free software only–GNU/Linux as the operating system, Mozilla as the browser, and a suite of media production software, most of which I had never seen on any machine anywhere.

Today we can chat about the question of “Who Owns Culture?” . A lot of this has been copped from an article in the New York Times.
The New York Times reported on a public lecture (sponsored by Wired magazine but I couldn’t find any mention of it on their site… so I guess we can scratch them from the running as potential owners of culture) – a discussion of digital file-sharing, part of a library series called “Live From the NYPL.” Both Jeff Tweedy, the leader of Wilco, and Lawrence Lessig, a Stanford University law professor who has opposed criminalizing file sharing, seemed to agree that just about anybody who owns a modem also owns – or at least has every right to download – culture products.
“I don’t think anybody should make any money on music,” Mr. Tweedy said at one point, only half joking.
“Maybe we would pay audiences.” . Obviously Mr Tweedy has never worked in Melbourne pubs where “paying to play” is almost the rule… but this isn’t a discussion on door deals so we will move on. Continue reading “So Who Owns Culture?”
Well today we can talk about Reality Hacking. This group/person/hive collective I stumbled over some years ago in 1999 with “Cattle Scrabble“, they painted white letters on 65 cows. There is a whole bunch of other stuff they do. Check out the Permission Denied link. Sick puppies… really sick puppies.
Some of you have passed some thoughts about the Yesterdays Post (Car Pipe Organs). Now for those of you who were less than generous. Check this out.
The Parasitic Power Shoes Project (thanks to the hackaday team for pointing this site out)
As the power requirements for microelectronics continue decreasing, environmental energy sources can begin to replace batteries in certain wearable subsystems. In this spirit, this effort has examined devices that can be built into a shoe, (where excess energy is readily harvested) and used for generating electrical power “parasitically” while walking. Two of these are piezoelectric in nature: a
unimorph strip made from piezoceramic composite material and a stave made from a multilayer laminate of PVDF foil. The third is a shoe-mounted rotary magnetic generator, an early version of which is currently exhibited at the London Museum of Science and Industry. As a self-powered application example, a system had been built around the piezoelectric shoes that periodically broadcasts a 12-bit digital RFID as the bearer walks.
And then there are the rest of the projects
Car Pipe Organ Orchestra’s are looking pretty tame now by comparison
For the last couple of days I have been thinking about car pipe organs again. This is an idea from some years back. The basics are fairly simple, you have a number of cars driving along a freeway side by side. On the top of the cars are long metal tubes of various lengths and diameters and as the car hits the right speed the velocity of the air travelling through the pipe will resonate and a note will sound. So the theory is that if the cars drive along speeding up and slowing down they will be able to play a tune. Now there are a number of things that need to be worked out I agree, but in principle it should work.
The reason that this is back in the front of my consciousness as opposed to hiding down the back with all the other scary thoughts is that I saw a show on the Crucible ( a blacksmiths shop in San Francisco not the play) and they were playing with flame throwers mounted on the top of their trucks and it got me to thinking (hey you down the back there… yes you the car pipe organ thought. Come up the front here for a minute) that maybe by squirting flame down the pipes you would lower the density of the air in the pipe and get a bit better control over the pitch.
Anyway thats as far as the thought has got at the moment (OK thought, back into storage.). I need to find a pyromaniac and see what they think. Dont you just love it when art , physics and madness all intersect?
