Many were outraged when Darrell Whitelaw tweeted a picture of Dropbox denying his ability to share a folder due to a DMCA (Digital Millennium Copyright Act) takedown request. Whitelaw later admitted that he was indeed trying to share a copyrighted video with a public link. Dropbox has explained to Ars Technica that it does not scan private documents, nor did it remove the file from Whitelaw’s account, but it does compare hashes of publicly shared files against the hashes of files that have already been served a notice. The DMCA requires companies like Dropbox to take measures to ensure that copyrighted material is not shared after a takedown notice has been issued. Whitelaw himself told Ars, “They’re just following the laws laid out for them. Was just surprised to see it.” follow link
See All Your Books in iBooks
The iBooks app for iOS lets you assign your books to different collections, but does not have any obvious way for you to see all of your books, regardless of the collection you have put them in. There is, however, a workaround that can show you just about all of your books at once: reveal the search field at the top of any collection in iBooks and type a single space into that field.
With this search, iBooks lists all of the books that have a space either in the title of the book or in the author's name. Other than the rare book that has a one-word title and a single-name author, you end up with a list of all of your books.
