SVG demo

If you are running Firefox (no idea what other browsers this works with) take a moment to play around with photos.svg. This is a reimplementation of one of the Microsoft Silverlight demos using SVG and Javascript. It may be slightly slow but I think many people will be surprised that this level of interactivity can be accomplished on a web page.

After you are done playing with the above take a look at the SVG video demo. It is basically the same demo as above but has movies playing instead of static pictures. Unless you run a development version of Firefox you’ll just have to watch the videos.

Torvalds interview

Q&A: Torvalds on Linux, Microsoft, software’s future

CW: Lots of researchers made millions with new computer technologies, but you preferred to keep developing Linux. Don’t you feel you missed the chance of a lifetime by not creating a proprietary Linux?

Torvalds: No, really. First off, I’m actually perfectly well off. I live in a good-sized house, with a nice yard, with deer occasionally showing up and eating the roses (my wife likes the roses more, I like the deer more, so we don’t really mind). I’ve got three kids, and I know I can pay for their education. What more do I need? . . . So instead, I have a very good life, doing something that I think is really interesting, and something that I think actually matters for people, not just me. And that makes me feel good.

The original network neutrality problem

From History of the Public Switched Telephone Network:

  • 1884
    • AT&T is incorporated as a subsidiary of American Bell
    • Bell Telephone creates the first long distance connection from Boston to New York City
  • 1891
    • Almon Strowger receives patent for his automated electromechanical call switching device
      “No longer will my competitor steal all my business just because his wife is a BELL operator.”
  • 1899
    • AT&T buys out American Bell assets.
    • Cleyson Brown founds Bell System competitor Brown Telephone (eventually becomes Sprint)

Somehow that comment seems relevant given the current net neutrality debate.

A map of the Internet

From Mapping the Internet:

The researchers’ results depict the Internet as consisting of a dense core of 80 or so critical nodes surrounded by an outer shell of 5,000 sparsely connected, isolated nodes that are very much dependent upon this core. Separating the core from the outer shell are approximately 15,000 peer-connected and self-sufficient nodes.

Take away the core, and an interesting thing happens: about 30 percent of the nodes from the outer shell become completely cut off. But the remaining 70 percent can continue communicating because the middle region has enough peer-connected nodes to bypass the core.

The right to attach

Hooking up by Tim Wu presents an idea on how to increase the competition around wireless (cellular) devices.

The firms already control what phones or devices reach Americans; 95% of cell phones are sold by the wireless carriers themselves. They strictly control phone design, blocking features that might threaten their revenue, like timers that keep track of how many minutes you’ve used each month.

The right to attach is a simple concept, and it has worked powerfully in other markets. For example, in the wired telephone world Carterfone rules are what made it possible to market answering machines, fax machines and the modems that sparked the Internet revolution.

A couple of books

Picture of booksI recently finished reading a couple of books which I think are worth pointing out to others.

The first is The World Is Flat: A brief history of the twenty-first century by Thomas L. Friedman. At 571 pages this a relatively long book. The first two hundred and thirty pages explain what the author means by “the world is flat” and describe the “ten forces that flattened the world”. The basic idea is that modern telecommunications and economic liberation has brought people all over the world closer together than ever before. On the surface this is a pretty obvious observation but the true impact of it only becomes apparent with deeper investigation. The author spent a great deal of time interviewing people in both developing and established economies in an attempt to understand the effects of these changes. The topics discussed range from software outsourcing to India to Walmart’s global supply chain. Subsequent chapters discuss the role of individuals, companies and countries in a flat world. In a way the world as outlined in this book is scary, especially if you are a knowledge worker but this book is as much about the opportunities created in a flat world as it is the negative consequences. A lot of time is spent describing what types of jobs are not as prone to flat world competition and more importantly, describing the key attributes required for success in those jobs that will face new competition. This is perhaps one of the more enlightening aspects of the book. In short, The World Is Flat covers something that is changing the world at a pace much faster than most people are aware of. If you have or are planning a knowledge based career you owe it to yourself to read this book. Even if you have a job that does not lend itself to global competition read the book anyway. On a final note I have a renewed appreciation for the importance of the education system to the continued economic success and growth of society.

The second book I want to talk about is On Intelligence by Jeff Hawkins. Hawkins is a very successful technology entrepreneur who has a long standing obsession with figuring out how the human brain works. This is not a book about biology although biology does necessarily creep in at some points. The goal of On Intelligence is to put forward a model of how the brain works and what intelligence is. The first portion describes some of the traditional techniques associated with artificial intelligence such as neural nets and offers an opinion on why these approaches failed. Later chapters discuss the role of memory and go on to explain that memory and prediction form the core of intelligence. Perhaps the most interesting aspect of the book is the idea that there is a single ‘cortical algorithm’ which is used by the brain for such diverse tasks as vision processing and locomotion. This is a very interesting read and at only two hundred and thirty-five pages it doesn’t take long.

Free software/copyright conference at UWO

On Monday April 9th and Tuesday April 10th Western Law is hosting a conference at the University of Western Ontario in London, Ontario, Canada called Knowledge Policy for the 21st Century.

Speakers include:

The conference fee is pretty cheap so if you are in the area it may be a great event to attend.
