Who Invented the Internet, Anyway?

Steven Johnson, author of Future Perfect: The Case For Progress In A Networked Age, reminds us that the Internet wasn’t created by the government (and certainly not by Al Gore):

Like many of the bedrock technologies that have come to define the digital age, the Internet was created by — and continues to be shaped by — decentralized groups of scientists and programmers and hobbyists (and more than a few entrepreneurs) freely sharing the fruits of their intellectual labor with the entire world. Yes, government financing supported much of the early research, and private corporations enhanced and commercialized the platforms. But the institutions responsible for the technology itself were neither governments nor private start-ups. They were much closer to the loose, collaborative organizations of academic research. They were networks of peers.

Peer networks break from the conventions of states and corporations in several crucial respects. They lack the traditional economic incentives of the private sector: almost all of the key technology standards are not owned by any one individual or organization, and a vast majority of contributors to open-source projects do not receive direct compensation for their work. (The Harvard legal scholar Yochai Benkler has called this phenomenon “commons-based peer production.”) And yet because peer networks are decentralized, they don’t suffer from the sclerosis of government bureaucracies. Peer networks are great innovators, not because they’re driven by the promise of commercial reward but rather because their open architecture allows others to build more easily on top of existing ideas, just as Berners-Lee built the Web on top of the Internet, and a host of subsequent contributors improved on Berners-Lee’s vision of the Web.

If you like how Steven Johnson writes, I highly recommend his other book published in 2005: Mind Wide Open.

Is It Possible to Reassemble Shredded Documents?

I’ve always wondered how secure it was to shred documents, and if there was a feasible way for someone motivated enough to reassemble the pieces. Well, it turns out that there is a way.

According to BBC, a team of computer programmers from California have developed software they say shows that computers can, in theory, do most of the hard work in re-assembling shredded documents:

It works by matching up individual shreds based on minuscule clues in each shred – the contour of the tears, a barely-visible watermark, and traces of writing, for instance – and can work incalculably faster than a human undertaking the same task.

It was the successful entry in a document shredder competition launched this autumn by the US military, in an attempt to encourage research on what is essentially a maths problem – how to assemble a puzzle efficiently.

In October, the Defense Advanced Research Projects Agency (Darpa), the Pentagon’s research arm, offered $50,000 (£31,961) to the first team to reassemble five shredded hand-written documents and answer the puzzles contained in each of them.

There were more than 9,000 (!) entries to the DARPA competition. The winning team name? All Your Shreds Are Belong to US, an obvious riff on All Your Base Are Belong to Us. If you’re interested in finding out more, NPR has a soundbite with Octavio Good, the software developer of the team that won the DARPA challenge.
