Design: Small and simple The TP-Link TL-WR902AC is nothing if not simple in its design. You’ve got two Ethernet ports (one to connect the router to the network, one to connect a device to the router), a USB port, and a power adapter port. There’s a reset button, a switch for selecting one of three different modes, and the device comes packaged with just a short ethernet cable and an equally short power cable....

It’s also referred to as the Windows Tools Menu, Power User Task Menu, Power User Hotkey, WinX Menu, or the WIN+X Menu. How to Open the WIN+X Menu You can bring up the Power User Menu with your keyboard by pressing the WIN (Windows) key and the X key together. With a mouse, you can show the Power User Menu by right-clicking the Start button. On a touch-only interface, activate the menu by a press-and-hold action on the Start button or whatever right-click action is available with your stylus....

Using Measurements to Clear up the Cable Controversy A sample testing method used a Clio 10 FW audio analyzer and MIC-01 measurement microphone to measure the response of a Revel Performa3 F206 speaker in-room. The in-room measurement was required to assure that there’d be no significant environmental noise. Yes, the in-room measurement shows a lot of effects of the room acoustics, but that didn’t matter because here, since we’re looking only for the difference in the measured result when we changed cables....

Attack of the Germ-Killing Robots Swimming pools are a big deal during the pandemic as people try to find a way to relax while social distancing, but keeping a pool clean takes a lot of work. Ariel is a robot that cleans pools using solar power and algorithms. Its manufacturer, Pivot-Solar Breeze, claims Ariel can maneuver itself to clean up to 95% of dirt, leaves, pollen, dust, hair, oil, and other icky things before the debris decays and sinks to the bottom....

SLAM: Simultaneous Localization and Mapping SLAM is an acronym for simultaneous localization and mapping, a technology whereby a robot or a device can create a map of its surroundings and orient itself properly within the map in real time. This is no easy task, and it currently exists at the frontiers of technology research and design. A big roadblock to successfully implementing SLAM technology is the chicken-and-egg problem introduced by the two required tasks....

What Causes 403 Forbidden Errors Different web servers report 403 Forbidden errors in different ways, the majority of which we’ve listed below (see the Common 403 Error Messages section). Occasionally a website owner will customize the site’s error, but that’s not too common. These errors are caused by issues where you’re trying to access something that you don’t have permission for. The error is essentially saying “Go away and don’t come back here” because the server’s access permissions indicate that you’re truly not allowed access or the permissions are actually improperly set up and you’re being denied access when you shouldn’t be....

A checksum is also sometimes called a hash sum and less often a hash value, hash code, or simply a hash. A Simple Checksum Example The idea of a checksum or a cryptographic hash function might seem complicated and not possibly worth the effort, but we’d like to convince you otherwise! Checksums really aren’t that hard to understand or create. Let’s start with a simple example, hopefully showcasing the power of checksums to prove something has changed....

Power Amplifier Channel Configurations Power amplifiers come in several channel configurations, from one channel (referred to as a monoblock) to two (stereo) channels. For surround applications, power amplifiers may feature five, seven, or more channels. When nine channels are needed, both seven and two-channel power amplifiers may be employed. When 11 channels are needed, a seven-channel amplifier is teamed with two two-channel amplifiers. A monoblock amplifier can be used for each channel, which calls for a lot of amplifiers....

Broadband internet connections are superior to the classic dial-up method which needed to be manually activated and was limited to performing one task at a time such as making a phone call or connecting to the web. What Does Broadband Mean? The technical definition of broadband is that of a method of data transmission that can support two or more traffic types simultaneously due to its capability of supporting a wide, or broad, band of frequencies....

Shared content can be made publicly accessible, or it can be shared only among a select group of friends or family, or with a single person. How Facebook Began Facebook began in February of 2004 as a school-based social network at Harvard University. It was created by Mark Zuckerberg along with Edward Saverin, both students at the college. It wasn’t until 2006 that Facebook opened to anyone 13 years or older and took off, rapidly overtaking MySpace as the most popular social network in the world....

The idea behind the app was to create a photo scanner that works with existing photo storage and sharing applications. That means you can capture images with PhotoScan and store them in Google Photos, Dropbox, or any other cloud storage service. How Google PhotoScan Works One of the best features of PhotoScan is that as long as you carry your smartphone, you have a photo scanner with you. You could use the camera on your device to capture a picture of a picture, but if you’ve ever tried to do that, you know that fighting glare, ambient light, and flashes is a tricky task....

The Original iPad Air The iPad Air was the first tablet powered by a 64-bit chip. While the jump from 32-bit to 64-bit was originally dismissed as being more a novelty than a technological leap, the improvement turned out to be a nice boost in power for the iPad. The iPad Air is roughly twice as fast as the iPad 4 that preceded it. The iPad Air also includes the M7 motion co-processor, which is dedicated to processing signals from the various motion-detecting sensors in the iPad....

What Is Midori? “Midori” is the Japanese word for green. That name doesn’t actually hold any significance to the web browser, other than the logo is a green cat paw. Name aside, Midori is a minimalist web browser that focuses on being lightweight by reducing the number of features. In other words, it’s simple to use (with a few caveats) and renders websites very quickly. As you might expect, the feature set for Midori is pretty bare bones....

What Is Twitter Auto-Follow? Twitter auto-follow refers to various methods, software programs, and incentives used to generate followers automatically for an account on the social network. The most common characteristic among these tools is automation. Typically, many follower connections are made automatically on Twitter by software, rather than manually by the Twitter user. Auto-follow methods usually rely on reciprocal following, which means following the people who follow you. That’s a common practice on Twitter and auto-follow tools make it easier to do....

The Details Are Vague Most of this acronym refers to LEDs, or “light-emitting diodes,” a lighting technology you’re probably familiar with. It’s the same LED technology found in modern home light bulbs and automotive headlights. The “Ultra” in ULED is a marketing term created by Hisense to describe a range of in-house technology. Hisense only applies the term to its mid-range and top-tier LED televisions. ULED lets you know the television you’re looking at is among the company’s best LCD TVs....

Digital beamforming technology is part of the 802.11ac standard for Wi-Fi routers. Sounds confusing, right? Don’t worry about the jargon. A standard for computers is much like a language. We both need to know the rules — grammar, spelling, etc. — to effectively communicate with each other. Our Wi-Fi router and our laptops, smartphones, and tablets also need rules on how to talk to each other. The 802.11ac standard is simply the newest set of rules....

Overall Findings Both LCD and LED TV screens and monitors display a bright, high-definition picture. If you want to save money on the hardware, go with the older LCD setup. LED screens may offer more cost savings over time, however, because the system generally requires less energy to operate. Although more expensive, newer LED screens are generally lighter than LCDs, especially on an edge-lit display that has fewer components to add bulk to the device....

If the problem is with LinkedIn, all you can really do is sit back and wait for it to be resolved. But if the problem has something to do with your account, your app, your machine or your device, there are a few things you can do to try to get it working again. Check Reputable Sources to Find Out If LinkedIn Is Experiencing Problems Before assuming that the problem is with you, you need to confirm that it’s not occurring on LinkedIn’s end and therefore affecting a large number of users....
