Richard Bennett Invites Me To A Panel On Tuesday March 2

Harold February 25, 2010 February 24, 2013General, Tales of the Sausage Factory

Back in October, Richard Bennett wrote a paper on why he thought network neutrality was particularly inappropriate — indeed, dangerous to the future evolution of — mobile internet access. On Tuesday March 2, his employer, The Information Technology & Innovation Foundation will be hosting an event to discuss the paper, mobile internet access and policy. He’s asked me to join Barbara Esbin from Progress and Freedom Foundation and Morgan Reed from the Association for Competitive Technology on a panel to discuss the issues. Should be fun.

Stay tuned . . . .

Towards an Economic Understanding of…Ourselves?

Stearns December 3, 2005 February 24, 2013Inventing the Future, meta-medium

If the dominant medium of a culture defines it, what does it mean for us when TV is changing? How will it change, and how will that change us? A couple of MIT academics are discussing the former at here. Good reading, but missing the point.

Scaling to the Enterprise (Part 2 of 4)

2. HOW MUCH USE CAN THE APPLICATION SUPPORT?
(See part 1.)

The architecture of Croquet is very different from that of, for example, J2EE applications. In a client-server application, one server or server “farm” must process each and every interaction initiated by the thousands or millions of users. The only thing processed on the end-user’s computer may be as little as the HTML formatting of the text and image results. Every single other computation must be handled on the big-iron servers. To double the number of users, the capacity of the servers must be doubled. It should be no surprise, then, that so much effort goes into trying to squeeze out each available computing cycle in such architectures.

When an application has state — that is, when results depend on previous results rather than simply generating static files — client-server does MUCH worse. The amount of storage required can go up much faster. In some cases the application state depends on the number of possible connections between users or between applications. The storage (and certain kinds of search-like operations) increases as the square of the number of users or applications (N^2, c.f. Metcalfe’s law). But we are particularly interested in allowing students and faculty to form their own ad-hoc groups among which to communicate and solve problems. A client-server architecture hosting such “group forming” applications would grow exponentially to the number of users (2^N, c.f. Reed’s 3rd law). With only a few users, this architecture would not work at all, no matter how (finitely) fast the servers, or what language the application is written in. (See Reed’s discussion for a surprisingly accessible treatment of value, saturation, and other issues.)
