He further suggests that if anything, the "new" literacy should be modeling — the ability to create a representation of a system that can be explored or used. "Defining a system or process requires breaking it down into pieces and defining those, which can then be broken down further. It is a process that helps acknowledge and remove ambiguity and it is the most important aspect of teaching people to model. In breaking parts down we can take something overwhelmingly complex and frame it in terms that we understand and actions we know how to do."
Now, both Apple and Google are providing full encryption as a default option on their mobile operating systems with an encryption scheme they are not able to break themselves, since they don't hold the necessary keys.
Some corporations have gone as far as turning to "zero-knowledge" services, usually located in countries such as Switzerland. These services pledge that they have no means to unlock the information once the customer has entered the unique encryption keys. This zero-knowledge approach is welcomed by users, who are reassured that their information is impossible to retrieve — at least theoretically — without their knowledge and the keys.
IBM brings out a new mainframe about every three years, and the success of this one is critical to the company's business. Mainframes alone account for only about 3 percent of IBM's sales. But when mainframe-related software, services and storage are included, the business as a whole contributes 25 percent of IBM's revenue and 35 percent of its operating profit. Ronald J. Peri, chief executive of Radixx International was an early advocate in the 1980s of moving off mainframes and onto networks of personal computers. Today Peri is shifting the back-end computing engine in the Radixx data center from a cluster of industry-standard servers to a new IBM mainframe and estimates the total cost of ownership including hardware, software and labor will be 50 percent less with a mainframe. "We kind of rediscovered the mainframe," says Peri.
Sony illustrates the reason why not. The hackers published old e-mails from company executives that caused enormous public embarrassment to the company. They published old e-mails by employees that caused less-newsworthy personal embarrassment to those employees, and these messages are resulting in class-action lawsuits against the company. They published old documents. They published everything they got their hands on."
Schneier recommends organizations immediately prepare a retention/deletion policy so in the likely event their security is breached, they can at least reduce the amount of harm done. What kind of retention policy does your organization enforce? Do you have any personal limits on storing old data?
What will all that money get you? 128GB of onboard storage and a microSD slot to go with it. There's a large touchscreen, and the device runs Android — but it uses version 4.2 Jelly Bean, which came out in 2012. It also supports Bluetooth and NFC. Sony claims the device has 33 hours of battery life when playing FLAC files, and 60 hours when playing MP3s. They appear to be targeting audiophiles — their press release includes phrasing about how pedestrian MP3 encoding will "compromise the purity of the original signal."
Today, the New England ice trade, which Tudor started in Boston's backyard in 1806, sounds cartoonishly old-fashioned. The work of ice-harvesting, which involved cutting massive chunks out of frozen bodies of water, packing them in sawdust for storage and transport, and selling them near and far, seems as archaic as the job of town crier. But scholars in recent years have suggested that we're missing something. In fact, they say, the ice trade was a catalyst for a transformation in daily life so powerful that the mark it left can still be seen on our cultural habits even today. Tudor's big idea ended up altering the course of history, making it possible not only to serve barflies cool mint juleps in the dead of summer, but to dramatically extend the shelf life and reach of food. Suddenly people could eat perishable fruits, vegetables, and meat produced far from their homes. Ice built a new kind of infrastructure that would ultimately become the cold, shiny basis for the entire modern food industry."
