If you’ve ever used a computer, you’ve probably seen it: A grid of numbers and mathematical operators on the far-right side of a keyboard. 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. In Sundstrand’s adding machine key layout, you can see the rudiments of now-standard setup: ten numeral keys, arranged in three rows of three with the … [Read more...] about Where Did the Numeric Keypads on PC Keyboards Come From?
Slideshows are an intuitive way to share complex ideas with an audience, although they’re dull and frustrating when poorly executed. Here are some tips to make your Microsoft PowerPoint presentations sing while avoiding common pitfalls. Table of Contents Start With a Goal Less Is More Consider Your Typeface Make Bullet Points Count Limit the Use of Transitions Skip Text Where Possible Think in Color Take a Look From the Top Down Bonus: Start With Templates Start With a Goal It all starts with identifying what we’re trying to achieve with the presentation. Is it informative, a showcase of data in an easy-to-understand medium? Or is it more of a pitch, something meant to persuade and convince an audience and lead them to a particular outcome?

Whatever wireless Xbox controller you have—whether it’s a controller for an Xbox Series X, Xbox Series S, or Xbox One—more battery life is always good. Here are our top tips for extending your controller’s battery life, both in the long and short term. Power off Your Controller to Save Battery The easiest way to make your controller’s batteries last longer is to simply turn it off when you aren’t using it. You can do this manually at any point while playing a game: Press and hold the Xbox button in the middle of the controller, then choose “Turn Off Controller.” If you don’t touch your Xbox controller for 15 minutes, it will power off automatically. Unfortunately, there’s no way to override this setting at present (as you can on Sony PlayStation consoles). Got a Play and Charge Kit? Charge Smart The Xbox controller comes with a single set of disposable batteries. The easiest way to upgrade your controller to be rechargeable is to purchase Microsoft’s official Play … [Read more...] about How to Extend Your Xbox Controller’s Battery Life
The sun sets depressingly early during certain times of the year, and this can have a big effect on your mood. What if you could control when the sun rises and sets with a fake natural light window? We’ll show you how to tackle this DIY project. Why a DIY Natural Light Window? If you live in a location where there are extended periods of darkness, you know how important natural light can be.

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. Anyone, no matter his or her interests, can surf the Internet for goods and services and make quick transactions. A student in New York City writing a major thesis on current Japanese animation can … [Read more...] about How does information technology work with trade laws?
Computational photography is responsible for most of the amazing strides our smartphone cameras have taken in the last decade. Here’s how it works, and how it makes our photos so much better. The Magic of Computational Photography Computational photography uses digital software to enhance the photos taken by a camera. It’s most prominently used in smartphones. In fact, computational photography does the heavy lifting to create the great-looking images you see in your smartphone photo gallery. The rapid improvement in smartphone cameras over the last few years can largely be attributed to improving software, rather than changes to the physical camera sensor. Some smartphone manufacturers, like Apple and Google, continuously improve the photo-taking capabilities of their devices year after year without ever drastically changing the physical camera sensors. Why Does Computational Photography Matter? How a camera digitally captures a photo can be roughly divided into two … [Read more...] about What Is Computational Photography?
