Wikidata, a centralized structured data repository for facts and Wikimedia’s first big new project in the last 7 years, is now feeding the foundation’s main project, Wikipedia. The Wikidata project was kicked off around a year ago by the German chapter of Wikimedia, which is still steering its gradual development. For Wikipedia, the advantage is simple and powerful – if there’s a central, machine-readable source for facts, such as the population of a city, then any update to that data can be instantly reflected across all the articles in which the facts are included.

It turns out that I’ve given authorization to apps and websites which I don’t remember why and when I gave to them. I don’t even remember what these do.

ABSTRACTHighly available cloud storage is often implemented with complex, multi-tiered distributed systems built on top of clusters of commodity servers and disk drives. Sophisticated management, load balancing and recovery techniques are needed to achieve high performance and availability amidst an abundance of failure sources that include software, hardware, network connectivity, and power issues. While there is a relative wealth of failure studies of individual components of storage systems, such as disk drives, relatively little has been reported so far on the overall availability behavior of large cloud-based storage services.
