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.

Encryption Cracked by Listening to a Computer’s CPU

If this were a movie, we’d be laughing at the improbability of the premise — that encryption can be cracked by listening to the high-pitched sounds produced by a computer’s CPU as it decrypts data. But it’s real, and although it can be done at a distance of 4 meters with a parabolic microphone, the researchers (Daniel Genkin, Eran Tromer, and Adi Shamir, who is the S of the RSA cryptosystem) also showed that it could be done with a smartphone sitting next to a laptop. Upping the ante, they suggest that a microphone hidden inside a colocated server could eavesdrop on numerous nearby servers. In short, if security is paramount, both heavy-duty encryption and physical protection are necessary.favicon follow link

As far as electromagnetism is concerned, we all live in glass houses. Just keep building better blinds.
