It’s a numeric keypad—but how did it get there, and why is it laid out the way it is? Let’s explore its origins. It’s All About the Math Computers have numeric keypads because they make repetitive data entry easier. They allow you to type numbers and perform mathematical operations rapidly, with only one hand. The modern design of numeric keypads may seem obvious today, but it is the product of decades of refinement in adding machine technology, most of which took place over 100 years ago. The modern numeric keypad layout—sometimes called a “tenkey” layout—can trace its roots back to David Sundstrand, whose company released the first commercial tenkey mechanical adding machine in 1914.

Starting in December 2020, the iPhone app store now provides “App Privacy” labels on all of its App Store listings. Using this information, you can make an informed decision about how apps track you and respect your privacy before downloading an app. Here’s how. Why Apple’s Sudden Focus on Privacy? With the launch of iOS 14 last year, Apple recently began putting a stronger public focus on privacy issues in smartphones and the apps that run on them. It’s a way for Apple to differentiate itself from its competitors, and if done well, Apple’s privacy safeguards can benefit its customers. Until recently, the ways iPhone and iPad apps could track you or use your personal data wasn’t entirely transparent to the user. Apple has set out to change that with new App Store labels that represent a sort of “Nutritional Label” for digital privacy. At a glance, you are now able to see the privacy performance of each app and decide whether it fits your personal comfort level. … [Read more...] about How to See an iPhone App’s Privacy Details Before Installing It

" " Visitors crowd the IBM stand at the CeBIT technology trade fair on the first day the fair opened to the public on March 4, 2008, in Hanover, Germany. Sean Gallup/ Getty Images Some people might tell you the world is getting smaller, and sometimes it seems that way. This is especially apparent in the things we buy. Many products you can find in the United States, such as clothing and toys, are manufactured overseas in countries like China and India. A lot of the gasoline someone might purchase to fill up a car probably comes from an oil refinery in a faraway country. Food grown on a farm in the Midwest can be shipped to the other side of the world in less than a day. The ubiquity of the Web has made these networks of trade even quicker to form and more complex.
