A conversation with the founders of Princeton’s Center for Information Techology Policy

As information technologies weave their way into every aspect of our personal, professional, and civic lives, there’s a growing need for informed public discussion of their public policy implications. Princeton’s Center for Information Technology Policy (CITP) is one emerging forum for that discussion. My guests on this week’s Innovators show are Ed Felten [...]

Silicon-based flow control for smarter/cheaper air conditioning and refrigeration

One of the key themes in Amory Lovins’ series of talks on energy efficiency in buildings is the energy lost when pumping fluids. At DEMO today, a company called Microstaq showed a silicon-based valve that promises to dramatically reduce the power required to move fluids through air conditioning and refrigeration systems. Current refrigerant expansion valves, [...]

Annotating DNS with personal information

I’ve always had a fondness for solutions that scribble in the margins of the Domain Name System. Today I saw a new one at the DEMO conference: Telnic, a service you can use to store basic personal or business information directly in the DNS. The service is associated with the .tel top-level domain. If you [...]

21st century Yankee ingenuity

Serendipity brought me a copy of this article on Jock Gill’s vision of small-scale grass farming operations. He thinks they’ll be able to produce biomass fuel, in a sustainable and decentralized way, for local production of heat and power. We had a long talk about this, and related themes, which will appear in two upcoming [...]

The World Bank’s web of data could be webbier

As Stefan Tilkov notes tearfully, the REST API for the World Bank data leaves something to be desired. The URI to fetch the list of countries looks like this: http://open.worldbank.org/rest.php?method=wb.countries.get In my review of the Leonard Richardson and Sam Ruby book RESTful Web Services I summarized their best practices for making a service “look like the web”: Data [...]

World Bank data now available through APIs

By way of David Stephenson I’ve learned that the World Bank now offers an API for several of its data sets on development, governance, and business conditions, plus a collection of photos. Here are the indicators you can explore, for many countries, going back to about 1960 (though the data are sparse in some cases): Agricultural land [...]

Freebase, Wikipedia, Powerset

Athough I’ve explored Freebase in several ways, I hadn’t seen the way it is now integrated — along with Wikipedia — into the Powerset demo of natural language search. It’s quite eye-opening to see the answer to a deceptively simple query like Tim O’Reilly’s siblings. Assuming that a database goes to the trouble of actually knowing [...]

Activating the web: One programming language or many?

Google’s newly-announced browser, which bakes in a JavaScript-specific virtual machine, reminds me of an earlier era in which the Netscape browser baked in support for the Java VM. It makes perfect sense for Google under the circumstances, but also serves as a reminder that language-specific runtimes aren’t the only game in town. From that perspective, [...]

New England’s biomass-fueled home heating future, part 2

The essay I posted last winter about New England’s historic transition from oil-fired home heating to biomass-fired alternatives has been read consistently ever since. Here’s a Labor Day 2008 update. As is typical in New England homes, my 1870-era home isn’t conducive to space heating. Which makes you wonder why open plan wasn’t fashionable back then. [...]

Trident: A workflow system for doing data-intensive science with reproducible results

Another of the many interesting stories coming out of Microsoft External Research these days is the one Roger Barga tells in this week’s installment of Perspectives. When Roger told me that Trident, the system he’s developing to automate scientific workflow, was inspired by Jim Gray, it was a déjà vu moment. Everywhere I turn, I [...]
