- Peer to Peer Markets (PDF) — We discuss elements of market design that make this possible, including search and matching algorithms, pricing, and reputation systems. We then develop a simple model of how these markets enable entry by small or flexible suppliers, and the resulting impact on existing firms. Finally, we consider the regulation of peer-to-peer markets, and the economic arguments for different approaches to licensing and certification, data, and employment regulation.

- HTML5 Video on iOS (Steve Souders) — While it’s true that Mobile Safari on iOS doesn’t buffer any video data as a result of the PRELOAD attribute, it does make other video requests that aren’t counted as “buffered” video. The number and size of the requests and responses depends on the video. For larger videos the total amount of data for these behind-the-scenes requests can be significant.

- Matasano Crypto Challenges — Counting is not a hard problem. But cryptography is. There are just a few things you can screw up to get the size of a buffer wrong. There are tens, probably hundreds, of obscure little things you can do to take a cryptosystem that should be secure even against an adversary with more CPU cores than there are atoms in the solar system, and make it solveable with a Perl script and 15 seconds. Don’t take our word for it: do the challenges and you’ll see. People “know” this already, but they don’t really know it in their gut, and we think the reason for that is that very few people actually know how to implement the best-known attacks. So, mail us, and we’ll give you a tour of them.
MOOCs get the attention, but DIY and peer-to-peer exchange are more fertile grounds for development
Somehow, recently, a lot of people have taken an interest in the broadcast of canned educational materials, and this practice — under a term that proponents and detractors have settled on, massive open online course (MOOC) — is getting a publicity surge. I know that the series of online classes offered by Stanford proved to be extraordinarily popular, leading to the foundation of Udacity and a number of other companies. But I wish people would stop getting so excited over this transitional technology. The attention drowns out two truly significant trends in progressive education: do-it-yourself labs and peer-to-peer exchanges.
In the current opinion torrent, Clay Shirky treats MOOCs in a recent article, and Joseph E. Aoun, president of Northeastern University, writes (in a Boston Globe subscription-only article) that traditional colleges will have to deal with the MOOC challenge. Jon Bruner points out on Radar that non-elite American institutions could use a good scare (although I know a lot of people whose lives were dramatically improved by attending such colleges). The December issue of Communications of the ACM offers Professor Richard A. DeMillo from the Georgia Institute of Technology assessing the possible role of MOOCs in changing education, along with an editorial by editor-in-chief Moshe Y. Vardi culminating with, “If I had my wish, I would wave a wand and make MOOCs disappear.”
There’s a popular metaphor for this early stage of innovation: we look back to the time when film-makers made the first moving pictures with professional performers by setting up cameras before stages in theaters. This era didn’t last long before visionaries such as Georges Méliès, D. W. Griffith, Sergei Eisenstein, and Luis Buñuel uncovered what the new medium could do for itself. How soon will colleges get tired of putting lectures online and offer courses that take advantage of new media? Read more…

it is affordable by growing numbers of people–and it just has to find

Opponents can shed their rhetoric and reveal new depths to their thought when you bring them together for rapid-fire exchanges, sometimes with their faces literally inches away from each other. That made it worth my while to truck down to the MIT Media Lab for yesterday’s Workshop on Innovation, Investment and the Open Internet, sponsored by the Federal Communications Commission. The event showed that innovation and investment are not always companions on the Internet. An in-depth look at the current state of the debate over competition and network neutrality.
