I have a device that gives you the winning lottery numbers ahead of time, but it has only a 10% chance of being correct. Is it useful?

I wouldn't be surprised if this were a side effect of Europes (not-so) recent Restriction of Hazardous Substances laws, which mean manufacturers need to use unleaded solder, which leads to tin whiskers.
The whiskers grow slowly and cause no harm, until they do cause harm (maybe a couple years down the line) -- and when they do, it is often catastrophic.
It should say "the native depopulation and consequent re-forestation" rather than "native depopulation and deforestation". In current models, it doesn't make sense that deforestation leads to cooling.
Engineers at the University of California, San Diego are developing a system to include an ignored sector of music, deemed the 'long tail', in music recommendations. It's well known that radio suffers from a popularity bias where the most popular songs receive an inordinate amount of exposure. In Apple's music recommender system, iTunes' Genius, this bias is magnified. An underground artist will never be recommended in a playlist due to insufficient data. It's an artifact of the popular collaborative filtering recommender algorithm, which Genius is based on.
In order to establish a more holistic model of the music world, Luke Barrington and researchers at the Computer Audition Laboratory have created a machine learning system which classifies songs in an automated, Pandora-like, fashion. Instead of using humans to explicitly categorize individual songs, they capture the wisdom of the crowds via a Facebook game, Herd It, and use the data to train statistical models. The machine can then "listen to", describe and recommend any song, popular or not. As more people play the game, the machines get smarter. Their experiments show that automatic recommendations work at least as well as Genius for recommending undiscovered music."
