The Practice of Cloud System Administration, Volume 2 is a look into IT gone bad in some companies, and how doing it right can salvage enterprise use of cloud computing. The authors make 11 statements about computers and their networks on the first page of the book's preface. They ask which statements are true. If you get most of them correct, you probably have only one reason left to read this book: It will challenge some of what you hold valid. However, you most likely will get numerous wrong answers.

The new full-disk encryption feature that's enabled by default in Android 5.0 Lollipop comes at a hefty price in terms of performance, according to a recent benchmark report. In fact, when full-disk encryption is enabled, random read performance drops by 62.9 percent, while random write performance falls by 50.5 percent, AnandTech reported late last week. Sequential read performance, meanwhile, drops by a whopping 80.7 percent. The bottom line is "serious negative implications for device performance in any situation where applications are reading or writing to disk," the report concludes.

A sophisticated malware program called "Regin" has been used in systematic spying campaigns against a range of international targets since at least 2008, Symantec reported. Regin is a backdoor-type Trojan with a structure that displays a degree of technical competence rarely seen in malware, according to Symantec. "Its elegance is comparable to Stuxnet and [it is] much more elegant than Flame," said Scott Borg, CEO of the U.S. Cyber Consequences Unit. "It's a beautiful piece of architecture."

Has software glut got you down? Do you reuse passwords because creating unique ones for all your online accounts would cause a memory overload? If your answer to those questions is yes, you may be interested in a bit of jewelry called the "Everykey," by a startup with the same name. Everykey is a wristband that, combined with software and the cloud, removes the need to remember the countless log-in credentials we use every day. What's more, it will work with electronic locks, too -- like car doors.

Well Thanksgiving week is upon us here in the land of stars and stripes, and in anticipation of all the social events soon to besiege us, more than a few Linux bloggers have been practicing keeping their favorite barstools warm down at the blogosphere's Punchy Penguin Saloon. How chilly would those stools get if we were all flitting here and there from this party to that? It would be truly unkind. Much better to stay put and keep to ourselves in a comfortable place where inane small talk is frowned upon.

The Electronic Frontier Foundation has announced a nonprofit organization that will aim to secure the entire Web. Let's Encrypt, starting in summer 2015, will offer free server certificates to help websites transition from HTTP to the more secure HTTPS protocol. EFF is partnering with Akamai, Mozilla, Cisco, iDenTrust and University of Michigan researchers. HTTPS has been around for years, but "certificate management and TLS in general tends to be a bit of a black art," said Stephen Ludin, chief architect at Akamai.
