Define Your Requirements Database management systems (or DBMSs) can be divided into two categories: desktop databases and server databases. Desktop databases are oriented toward single-user applications and reside on standard personal computers (hence the term desktop). Server databases contain mechanisms to ensure the reliability and consistency of data and are geared toward multi-user applications. These databases are designed to run on high-performance servers and carry a correspondingly higher price tag. A careful needs analysis before you commit to a database solution is essential....

What Is Chrome Canary? Canary is an experimental version of the popular Chrome browser. Google offers four release channels for its browser: Stable, Beta, Dev, and Canary. Most people use the Stable release of the popular browser, which is rigorously tested and considered very reliable. By contrast, Canary may appeal to people who like noodling around with new technology and want to get an advance look at what the standard browser may look like in the future....

The DJI RoboMaster S1 is a remote-controlled toy on steroids. Looking more like the kind of driving drone that bomb squads or soldiers use, it’s hyper-maneuverable, with complex and versatile wheels that allow it to drive sideways and zip ahead at high speeds. It even shoots little gel pellets from its cannon and can capture photos and HD video. In all regards, the DJI RoboMaster S1 is a beast, and easily one of the most impressive connected toys we’ve ever seen....

How DTS Neo:X Works Like the ProLogic IIz and Audyssey DSX, DTS Neo:X does not require studios to mix soundtracks specifically for the 11.1 channel sound field. Still, DTS Neo:X has the ability, and doing so delivers a more accurate result. However, without optimizing the mixing end, DTS Neo:X looks for cues already present in stereo, 5.1, or 7.1 channel soundtracks. It places those cues within the front height and wide channels that are distributed to additional front height and rear height speakers, enabling a more enveloping 3D listening environment....

Systems like traction control and anti-lock brakes help you maintain control during acceleration and braking, but electronic stability control (ESC) is designed to prevent you from losing control in other circumstances. What’s the Point of Electronic Stability Control? ESC is supposed to keep a vehicle moving in the direction that the driver wants to go. Like anti-lock brakes and traction control, electronic stability control is an added safety measure. These systems won’t protect you from careless driving, but they help keep you on the road under adverse conditions....

The entry-level 13-inch M2 MacBook Pro, the one with the Touch Bar and the aging six-year-old case design, is already a bad choice, but the news gets worse. Its SSD, the storage’ disk,’ only operates at half the speed of its predecessor. It’s not a stretch to say that ever-faster SSDs have been the most important change in personal computers over the last decade, so this is a significant step backward....

One of the biggest criticisms of Eventide’s years-old H9 Harmonizer pedal was not its amazing array of effects or its build quality but the fact that you could only use one effect at a time. The H90 explodes that limitation, adds powerful new hardware, and—with a bright OLED screen and an array of knobs and buttons, it looks a lot easier to use, too. “They had created algorithms that combined certain effects, but you were limited to them and couldn’t just combine your favorites....

The gist of Opera’s latest feature works specifically through Yat, which allows users to create a custom web URL from a string of emojis—the resulting webpage can be customized or used as a redirect to a more typical website. Ideally, it would work as an attention-grabbing way for companies to get people to check out their websites, but experts are hesitant to view it as anything more than a fad....

Fitness trackers have come a long way over the last few years, and you can find options in a variety of shapes, sizes, styles, and price ranges. The Garmin Vivosmart 4 is priced in about the mid-range, and it offers a few cool perks in addition to the standards like calorie counting and step counting. I tested the Garmin Vivosmart 4 for a month to see how it performs compared to other similarly priced fitness trackers on the market....

Google’s experiment with pricey, full-blooded flagship phones has come to a seeming end as the company realizes its true strength: capable, affordable smartphones that emphasize Google’s smooth Android software rather than flashy hardware. We first got a glimpse of that with 2019’s Pixel 3a, a $399 mid-range phone that proved more compelling than the twice-as-pricey main Pixel 3, pairing modest specs with an excellent camera for a seriously brilliant package....

According to cybersecurity sleuths at Avanan, phishing actors have found a way to abuse Google’s SMTP relay service, which allows them to spoof any Gmail address, including those of popular brands. The novel attack strategy lends legitimacy to the fraudulent email, letting it fool not just the recipient but also automated email security mechanisms. “Threat actors are always looking for the next available attack vector and reliably find creative ways to bypass security controls like spam filtering,” Chris Clements, VP Solutions Architecture at Cerberus Sentinel, told Lifewire over email....

What Is an HFS File? A file with the HFS file extension is an HFS disk image file. HFS stands for hierarchical file system and is the file system used on a Mac computer for describing how files and folders are to be structured. This file, then, organizes data in the same way, except that all the files are contained in a single file with the .HFS file extension. They’re sometimes seen stored inside DMG files....

Jon Henshaw, founder of digital marketing insights firm Coywolf, kicked off the buzz with a blog post citing increased crawling activity on Applebot and an uptick in job postings for search engineers. “At this point, everything is based on observation and conjecture,” wrote Henshaw. “They may never release a search engine. It’s also possible that iOS, iPadOS, and macOS users will be using it and not even be aware of it....

Focus lets you customize who and what can grab your attention on your iPhone, iPad, and Mac. You can screen out contacts, apps, and notifications, and even hide or show different home screens, depending on the time of day, where you are, or what you are doing. And the most amazing part? It’s so simple to set up that you might actually do it. “iOS Focus is going to be a game-changer for our productivity and the way we manage our devices,” time management and goal-achievement mentor Alejandra Marqués told Lifewire via email....

An organization is working on the first Massive Multiplayer Online Open World with photorealistic graphics. Victoria VR is a shared virtual arena where users can do anything from play games to trade goods. It’s one of a growing number of virtual reality worlds in development trying to use blockchain. “Blockchain is important in our project due to its transparency, openness, and the impossibility of rewriting history and cheating,” Tomáš Bém, co-founder of Victoria VR, said in an email interview....

A new online app called Boomy bills itself as the first record label for everyone. Boomy uses artificial intelligence to help create music. It’s one of a growing number of online services that promise to smooth the process of putting music online, promoting it, and making money, even for less popular genres. “The problem with distributing classical music from independent composers and artists needs to be addressed,” Mitchell Hutchings, a professor of music at Florida Atlantic University, told Lifewire in an email interview....

A fabric developed by a team of scientists in China could replace many of the features of modern smartphones. The new material could have applications in communications, navigation, healthcare, and safety. It’s one of many smart fabrics being developed that promises to transform clothing and other objects into displays or computers. “Compared with the conventional rigid bulky or emerging thin-film electronic devices, the electronic fabrics are highly flexible, lightweight, and breathable,” Huisheng Peng, a professor at Fudan University in Shanghai and the lead author of a recent paper on the new fabric technology, said in an email interview....

Created by Rise Science, the RISE app debuted on app stores this week with a free seven-day trial. As someone who loves their sleep, but is often exhausted during the day, I thought I’d give the app a try to see if I could understand why I feel a certain way and improve my energy levels. After a few days of using it, the RISE app has given me the tools to be more productive and more energetic throughout the day....

Stealth is a large, bright-yellow piece of exercise equipment that has three parts: a platform for you to rest your arms on while you plank; a ball to let you move around to work more muscle groups; and your phone, which sits in a tray and displays games via a free app that hypothetically enhances the shredding process by guiding you through exercises without you even knowing you’re exercising. The Stealth’s idea of having something to focus on to distract from my entire body feeling like it’s on fire, or at least provide some sneaky guidance to my workout, is a good one....
