Free Your Feet with “Barefoot” Shoes   Soeren Kracht/Shutterstock Whether you’re an aspiring barefoot runner or just want to get in touch with your own feet, “barefoot” shoes are an excellent option for strengthening your legs and improving tactility. Here, we outline some of the best in minimalist footwear. There are plenty of articles out there about why, as a trail runner, you should try barefoot shoes. But, if you’re not a runner, should you even bother? Well, sure! Not Just for Trail Runners We’ve spoiled our feet with modern shoes. Thick soles and arch support have made our feet soft and weak—we seem to think our feet can’t touch the ground without being injured. Modern footwear encases our feet like armor. Throughout much of human history, our ancestors wore simple shoes with minimal support, like sandals or leather socks with some extra layering at the sole. They also wore things like kilts, tights, and three-quarter length pants. Why? Because they wanted to show off the impressive calf muscles they developed walking around and not wearing overbuilt shoes. For us, making the switch to minimal shoes presents a bit of a learning curve. Without the shock absorption of a thick heel, you’re forced to take advantage of your natural shock absorption mechanisms: ankles, toes, and foot muscles, rather than just landing on the heel bone and letting that shock ride up into your knees and back. But the challenge is the benefit. You’ll use your feet more, make your legs stronger, and absorb the impact where it was meant to go (your muscles), rather than where it tends to be absorbed now (by our shoes, bones, and joints). Wearing barefoot shoes even when you’re walking around town can strengthen your legs. You’ll also feel nimble enough to hop over a candlestick, and every other shoe will feel like a ski boot in comparison. Everyone is different, though. If you’ve had problems with your feet, consult with someone who has spent seven years at foot school before donning minimalist shoes. You’ll also find out what your dog already knows: pavement’s not as fun to walk on as dirt and grass.

Not All 5G Is Equal: Millimeter Wave, Low-Band, and Mid-Band Explained Marko Aliaksandr/Shutterstock You’ve probably heard that 5G uses the millimeter wave spectrum to reach its 10 Gbps speeds. But it also uses the low- and mid-band spectrums, just like 4G. Without all three spectrums, 5G wouldn’t be reliable. So, what’s the difference between these spectrums? Why do they transfer data at different speeds, and why are they all critical to 5G’s success? How Do Electromagnetic Frequencies Transfer Data? Before we get too deep into low-band, mid-band, and millimeter wave, we need to understand how wireless data transmission works. Otherwise, we’ll have trouble wrapping our heads around the differences between these three spectrums. Radio waves and microwaves are invisible to the naked eye, but they’re literally shaped like waves. As a wave’s frequency increases, the distance between each wave (the wavelength) gets shorter. Your phone measures wavelength to identify frequencies and to “hear” the data that a frequency is trying to transmit. Wikipedia But a stable, unchanging frequency can’t “talk” to your phone. It needs to be modulated by subtly increasing and decreasing the frequency rate. Your phone observes these tiny modulations by measuring changes in wavelength and then translates those measurements into data. If it helps, think of this as binary and Morse code combined. If you’re trying to transmit Morse code with a flashlight, you can’t just leave the flashlight on. You have to “modulate” it in a way that can be interpreted as language. RELATED: What Is 5G, and How Fast Will It Be? 5G Works Best with All Three Spectrums Wireless data transfer has a serious limitation: frequency is tied too closely to bandwidth. Waves that operate at a low frequency have long wavelengths, so modulations happen at a snail’s pace. In other words, they “talk” slow, which leads to a low bandwidth (slow Internet).

How to Make Word Documents Fillable but Not Editable If contracts are part of your daily workflow, you know how frustrating it is when people change parts of the document or form they shouldn’t. Fortunately, Microsoft Word has a developer tool that lets you protect the text in your document while still allowing people to fill in blanks. Making Your Document Fillable, Not Editable Let’s say, for example, that you have a non-disclosure agreement that you want to send out to an employee that will be joining your company. You want to give the receiving individual the ability the fill in the blanks in the document, but you also want to ensure that none of the information in the NDA is altered or changed in any way. It only takes a few steps to achieve this in Word. Here’s how. First, grab the legal document you want to work with. Microsoft provides a few basic templates, but there are also a lot of websites that provide detailed, comprehensive legal templates online for free, drawn up by actual attorneys. In this example, we’ll be using an NDA that we grabbed from the above link. Once you have your document pulled up, it’s time to add some controls and protection to it. First, you need to get into the “Developer” tab. Word doesn’t display this on the ribbon by default, so let’s go ahead and fix that. Click “File.” At the very bottom of the menu, select “Options.” Read the remaining 39 paragraphs

Daily News Roundup: Tinder Swipes Left on Google Pay When Google Apps take payments using Google Pay, Google takes a cut of the money. Now Tinder, the dating service app, wants to avoid that fee by setting its payments service as the default option. Google takes a 30% cut of in-app purchases. If the app offers a subscription, that amount drops down to 15% after the first year. Apple takes the same amount from purchases in its apps. Some app developers, however, feel the amount is too high. In some cases, this is coupled by complaints that Google and Apple develop competing services that don’t feel the pain of losing 30% of a sale (such as Spotify, YouTube Music, and Apple Music). Google (and Apple) requires app developers to use its payment system, but Tinder is ignoring that policy in a new update. Instead, the default payment option is through Tinder’s payment processor. Users input their credit card directly into the app, in lieu of using Google Pay. Since Tinder is handling the entire payment, Google doesn’t get a cut of the purchase. While users can switch the default method to Google Pay before they’ve made the first payment, once they’ve chosen to make a payment directly to Tinder the app saves the credit card details and removes the Google Pay option. Google hasn’t said yet if it plans to take any action against the policy violation. [Engadget] In Other News: Google’s Fast Pair will add features for Truly Wireless headphones: Android Q will add a few features to Bluetooth Fast pair that should make using Truly Wireless headphones a better experience. Android will show battery life for each earbud and the charging case. Additionally, the “find my device” feature will also report the last known headphone location. Awesome. [TechRadar] Equifax will pay up to $700 million for losing your data: In 2017, Equifax failed to patch a known flaw on its servers that led to a massive breach of its systems. 146 million users had everything from drivers license details to social security numbers stolen. Now Equifax is close to settling claims against it, and in the process paying out as much as $700 million. The company will also offer six free credit reports per year to users for seven years. [ZDNet] Asus announces the ROG Phone 2, a beast of a gaming phone: Asus took the wraps off its latest gaming phone, and on paper, it should be powerful and look gorgeous.

How to Enable Text Prediction for a Hardware Keyboard on Windows 10 Windows 10 offers predictive text, just like Android and iPhone. Microsoft calls this “text suggestions.” It’s part of Windows 10’s touch keyboard, but you can also enable it for hardware keyboards. Suggestions will appear floating over text as you type. This setting is available in Windows 10’s Settings app. To launch it, press Windows+I or open the Start menu and click the gear-shaped Settings icon. Click the “Devices” icon in the Settings window. Click “Typing” in the sidebar. Scroll down to the “Hardware keyboard” section and enable the “Show text suggestions as I type” option.   Read the remaining 9 paragraphs

How to Use the look Command on Linux Fatmawati Achmad Zaenuri/Shutterstock The Linux look command races through a file and lists all the lines that begin with a particular word or phrase. But watch out! It behaves differently on different Linux distributions. This tutorial will show you how to use it. Ubuntu’s look Command Behaves Differently For a simple, but useful, command, look certainly gave me the runaround when I was researching this article. There were two problems: compatibility and documentation. This article was checked using Ubuntu, Fedora, and Manjaro. look was bundled with each of those distributions, which was great. The problem was the behavior wasn’t the same across all three. The Ubuntu version was very different. According to the Ubuntu Manpages, the behavior should be the same. I eventually figured it out. look traditionally uses a binary search, while Ubuntu look uses a linear search. The online Ubuntu man pages for Bionic Beaver (18.04), Cosmic Cuttlefish (18.10), and Disco Dingo (19.04) all say the Ubuntu version uses a binary search, which is not the case. If we take a look at the local Ubuntu man page, we see it clearly states their look uses a linear search. There is a command-line option to force it to use a binary search. Neither of the versions in the other distributions has an option to choose between search methods. man look Scrolling down through the man page, we see the section that describes this version of  look using a linear instead of binary search. The moral of the story is to check the local man pages first. Linear Search versus Binary Search Read the remaining 52 paragraphs
