I use DOI’s all the time, for citations. They are so useful. I’m glad that ISO finally acknowledged DOI as a standard.
DOI prevents link rot!
Applications of the DOI system include (but are not limited to) managing information and documentation location and access; managing metadata; persistent unique identification of any form of any data…

"…a software tool for detecting equations and hidden mathematical relationships in your data. Its goal is to identify the simplest mathematical formulas which could describe the underlying mechanisms that produced the data."

via Wolfram Alpha adds powerful, interactive search results - TNW Apps
Wolfram Alpha has a blog right here on tumblr. I think they re-post articles from the online press and blogosphere, whenever their products, and interesting use cases, are featured. That’s why it appears that this story came from TheNextWeb.
The source site for all accumulated posts, plus links to Wolfram specific information is the Wolfram Alpha tumblr. Wolfram is even running a Win a free iPad2! contest. It is probably one of the few that is actually legitimate. Eligibility may be limited to students, though.
I didn’t realize how truly “search engine”-like Wolfram Alpha is. I thought of it as a very specific science and math ummmm, “computation engine”? It is more general than that. One can submit very finely targeted queries, over a wide assortment of topics. Examples:
- What is the frequency of occurrence, in % and absolute value, of any user-submitted last name/ surname in the U.S.A.?
- Password suggestions of varying lengths. No, I don’t know what cryptographic method is used to generate them, though I’m curious too!
These are one step queries, which is what I found impressive. There were many others, including that satellite position extravaganza image above.

ack 1.94 is source code search tool for programmers.
Is it better than Google Code Search? Possibly, if it is for those who live in a non-MS Windows world.

L’Italia in tempo reale
Italy in Real-time
Italiaora.org is an Italian-language search engine. Well, it is better described as a ”data query interface” than a Google or Yahoo! type search engine. Use it for querying publicly available data sets about the economy and people of Italy.
If you enjoy the U.S. government debt “live” counters, you will enjoy this site. There are quite a few of those counters scattered around on Italiaora.org!
The metrics are more novel than that debt counter we’ve seen forever and a day in Times Square:
- Number of years until global oil reserves are exhausted
- Number of children born, tallied in real-time
- Number of people dying of malaria etc
Most data is specific to Italy.
Some measures are global. All Gov 2.0 data sources, Italian and otherwise, are fully documented. The site is spartan, clean and could even be elegant without that new rival to Comic-sans: The Kristin* typeface.
* Kristin typeface appears with increasing frequency in the sub-titles of YouTube videos.
