Microsoft has open-sourced WorldWide Telescope. “WorldWide Telescope began in 2007 as a Microsoft Research project, with early partners including astronomers and educators from Caltech, Harvard, Johns Hopkins, Northwestern, the University of Chicago and several NASA facilities. Over the past eight years, millions of people have downloaded and used WorldWide Telescope, coming to rely on its unified astronomical image and data environment for exploratory research, teaching and public outreach.”
From the always-awesome Mary Ellen Bates, a couple of super searcher tricks. One of the tricks she mentions is restricting search to .gov sites only. If you want to search just government sites but want to search a slightly larger data pool than just .gov, check out this Google custom search engine I put together that restricts results to government Web sites (but it uses .gov and .us, so it’s got more resources to search. You can also narrow your results by city or county if the mood takes you.)
The Next Web has a roundup of 10 interesting Twitter chats. They seem to be mostly social media oriented. Which reminds me, as long as I’m complaining about things it’s hard to search for, let’s talk live Google Hangouts. Does anyone know of a good directory/calendar of live Google Hangouts? I know Google has a list of what’s live now, but I’m thinking about something where I can say, “Oh, I have a little time Friday, let’s see what’s going on.” I know I spend most of my time under this desk, but occasionally interacting with other humans has its appeal.
Interesting: using Twitter to detect earthquakes. “The Tweet Earthquake Dispatch (TED) system uses an API that compiles tweets based on keywords such as “earthquake” and its equivalent in multiple languages. Specifically, the API searches for significant increases in tweets containing the keywords. In addition to searching for keywords, the API has parameters to remove tweets that are more than 7 words, contain numbers, the ‘@’ symbol and words such as ‘http,’ ‘predict,’ ‘drill,’ and ‘song’ to eliminate tweets that are not related to an actual earthquake.” There’s also a Twitter account you can follow to get earthquake information.
Nice roundup from The Edublogger: how to embed just about anything. “Embedding videos, photos, or other types of content in your blog posts is a relatively simple way to enhance your posts with informative, attention-grabbing content.
