Comparison of e-book readers

Comparison of e-book readers
An e-book reader is a portable electronic device that is designed primarily for the purpose of reading e-books and periodicals. E-book readers are similar in form to a tablet computer, and usually refer to readers that use electronic paper, which means better readability of their screens especially in bright sunlight, and longer battery life. When disconnected from the web, an e-book reader's battery will last from weeks to months. A tablet computer typically has a faster screen capable of higher refresh rates which makes them more suitable for interaction. Any device that can display text on a screen can act as an e-book reader, but without the advantages of the e-paper technology. Commercially available devices sold by maker or designer[edit] Notes: Library DRM compatible – Can be used to borrow e-books from public libraries, i.e. the EPUB and/or PDF formats with digital-rights-management (DRM) are supported."

Metcalfe's law Two telephones can make only one connection, five can make 10 connections, and twelve can make 66 connections. Metcalfe's law states that the value of a telecommunications network is proportional to the square of the number of connected users of the system (n2). First formulated in this form by George Gilder in 1993,[1] and attributed to Robert Metcalfe in regard to Ethernet, Metcalfe's law was originally presented, circa 1980, not in terms of users, but rather of "compatible communicating devices" (for example, fax machines, telephones, etc.)[2] Only more recently with the launch of the Internet did this law carry over to users and networks as its original intent was to describe Ethernet purchases and connections.[3] The law is also very much related to economics and business management, especially with competitive companies looking to merge with one another.

How to Edit PDF Files - Free Tools for Manipulating PDF Documents The PDF file format was originally created by Adobe in the early ’90s and it now the most popular format for exchanging all sorts of documents including presentations, CAD Drawings, invoices, government forms and other legal documents. There are several reasons why PDF file format is so popular. PDFs are generally more compact (smaller in size) than the source document and they preserve the original formatting. The content of a PDF file cannot be modified easily and you can prevent other users from printing or copying text from PDF documents. Also, you can open a PDF file on any computer or mobile device natively. While PDF Files are “read only” by default, there are workarounds that will let you modify any PDF document for free without requiring the source files or any of the commercial PDF editing tools like Adobe Acrobat.

What's in a wine label? - Wine These days many enjoy buying wine with labels that feature animals: kangaroos, penguins, fish, lizards, and loons. These “critter labels” don’t just happen by accident — research shows that American wine consumers are 40 percent more likely to buy a wine with a cute animal on the label when compared to a straightforward label that gives the standard information: the name of the producer, the name of the grape, the name of the place where the vineyards are located, and the year in which the grapes were picked. But whether we choose our wines based on the cute factor or on the basic label facts, most wine labels give us minimal information; it’s up to the consumer to know about the vintage, the area where the grapes are grown, etc. Sometimes the back label of a wine is reserved for marketing the wine, and in the process of trying to hook the consumer with spinspiel, we learn a bit more about the origins of the wine and the philosophy of the producer. Let’s take a look. Filtration: None
