What Is a DM File? A file with the DM file extension is most likely a DRM Delivery Message file. It can be any file type but is usually an audio file used as a ringtone or media clip on a cell phone. They’re sometimes downloaded to a computer, too. Since these files are protected with DRM (Digital Rights Management) copy-protection software, a cell phone must be authorized in order to use them....

The short answer is, yes. Why Isn’t Windows Defender Good Enough? Windows 10 now provides built-in security in the form of Windows Defender, which includes both an antivirus and a firewall component. Many people opt out of installing third-party firewall software and only use Windows Defender. But is that really the best option? According to a study conducted by AV Comparatives, Windows Defender antivirus for Windows 10 performed well overall but fell short in a few important areas....

As both touch and non-touchscreen laptops have evolved, they’ve become incredibly lightweight and thin, making them more portable than ever. With an ultra-thin chassis, you can easily slip your new laptop into a backpack or tote for a work commute or carry-on bag for business travel without worrying about being worn down by weight. Another innovation for laptops is the inclusion of SSD storage and M.2 SSD compatibility. A solid state drive allows for faster boot times and file or program access than traditional hard-disk drives, and M....

Pricey Peloton bikes and other kinds of workout machines are all the rage during the coronavirus pandemic. I’ve been testing FightCamp’s offering, and it delivers a solid uppercut to the indoor cycling crowd. FightCamp aims to bring a boxing class to your home, and for the most part, it succeeds. It pairs a high-quality standing bag along with gloves and hand wraps that you insert Bluetooth trackers in. The trackers monitor your punches’ speed and frequency and guide you as you follow along with pre-recorded video workouts....

Don’t Get Too Close to the Subject Standing too close to a subject is one of the most common reasons a DSLR’s autofocus fails. Doing this makes it difficult for the autofocus to achieve a sharp result unless you’re using a macro lens. With a typical DSLR lens, you have to move farther back from the subject or you could end up with a blurred image. Avoid Direct Light That Causes Glare Strong reflections can cause a DSLR’s autofocus to fail or to misread the subject....

Sabala’s wit has captured audiences across Twitch and TikTok who tune in to watch his delightfully chaotic playthroughs. This natural-born storyteller moves to the beat of his own drum, and nearly 50,000 followers are marching along. “I feel very lucky that [my audience] has found [my channel], that it is there for them, and that they’ve stumbled upon it in one way or another. I look at the numbers, and I think they align with what I’m putting out there,” Sabala said in an interview with Lifewire....

Atomic defects in some crystals may help unleash the potential of the quantum computing revolution, according to discoveries made by Northeastern University researchers. The scientists said they had discovered a new way to make a quantum bit using the crystals. Advances in quantum technologies, which deploy the properties of quantum physics called entanglement, could allow for more powerful and energy-efficient devices. “Entanglement is a fancy word for creating a relationship between particles that makes them act like they are bonded together,” Vincent Berk, CRO & CSO of the quantum computing company Quantum Xchange told Lifewire in an email interview....

Google’s original Nest Hub showed why a smart assistant with a screen might be a good thing, packing a fair number of features into a compact, attractive form. The Next Hub Max takes things to another level, however, with a larger display, a Nest Aware camera on the front, and better sound quality—with a larger footprint, as well. Still, Google’s scaled-up smart display can blend in well with its surroundings and provides a litany of nuanced benefits that make it a welcome addition to any connected home....

Google Pixelbook Design The Pixelbook features high-end hardware and a premium design that incorporates an aluminum chassis along with Corning Gorilla Glass detail. The Pixelbook offers several configurations for a choice of processor, memory, and storage. At 0.4 inches (10.3 mm) thick when closed, the Pixelbook is strikingly slim, rivaling a 13-inch MacBook Pro. The Pixelbook has 360-degree flexible hinges, giving it a hybrid convertible design similar to the Microsoft Surface or Asus Chromebook Flip....

Touch is everywhere. It’s on our phones and tablets, but also thermostats, appliances, and now even an earbud charging case. In large part, one might say phones are so successful because of this flexibility, allowing them to be cameras, musical instruments, and even drawing pads. But this also means designers are never really forced to finalize a user interface. You can add a touchscreen and code a basic UI design, with the promise that any shortcomings can be fixed later....

Back in 2019, I bought my very first gaming laptop, and I’ve been sold on the idea of a portable writing and gaming computer ever since. As much as I love my gaming laptops, both of my models, an Eluktronics and an MSI, both feel like they’re about to catch fire whenever I’m playing a heavy-hitting game like Division or Destiny 2. A couple gaming sessions later, and I realized I needed a laptop cooling pad....

Most people associate hashtags with social media. These cyber appendages that internet users tack on to keywords are here to stay—at least into the foreseeable future. Hashtag History Metadata tags have been around for quite some time. Tags were first used in 1988 on a platform known as Internet Relay Chat or IRC to group messages, images, content, and video into categories. The purpose is so users can search for hashtags and find content associated with them....

The first thing to understand about Home Designer Pro by Chief Architect is that it’s the combination of all of the features and tools found in the Home Designer line of home, interior, and landscaping design programs. It has everything from floor plans and interior design tools to topography designers and plant encyclopedias. There’s literally nothing about your home’s physical manifestation that can’t be put into this program. A program this comprehensive is massive and takes a significant commitment in time and effort to learn how to use effectively....

A recently developed algorithm can predict planetary orbits without having to be told about Newton’s laws, according to a recent paper by Princeton University physicist Hong Qin. Qin’s research shows how the technology of a simulated universe could work in practice, experts say. “If an AI algorithm is able to predict the motion of planets, for example, using discrete field theory, this suggests that the universe, itself, may consist at some level of discrete elements—if you will, that the universe is pixelated,” computer scientist Rizwan Virk, the author of “The Simulation Hypothesis,” who was not involved in the research, said in an email interview....

CareCall is a new artificial intelligence (AI) system that checks in on seniors by giving them a call. It’s part of a burgeoning industry of AI tools and robots that could help assist people who are aging. However, there are concerns that AI-guided robot companions could end up replacing human contact for the elderly. “Robots must be sensitive and empathetic and compassionate, accompanying care acts with genuine concern and conveying feeling,” said Ron Baecker, an Emeritus Professor of Computer Science at the University of Toronto, where he founded the Technologies for Aging Gracefully Lab, in an email interview....

AI-generated content could mean many things today, including personalized news feeds catered to readers’ interests and written articles gleaned from a data set. With so much information available 24/7 at our fingertips, it makes sense to have AI step in and help curate some of the news we consume. “It just doesn’t make sense for humans to be going in and generating and putting together certain types of content because there’s no creativity—it’s just mind-numbing, and AI systems are good at the mind-numbing thing,” Ronald Schmelzer, a managing parter and principal analyst at Cognilytica, told Lifewire over the phone....

Employees are planning ways to handle the public under these conditions, as well. Some felt they had to leave the company for fears of contracting the highly contagious virus after plans to reopen were cemented in a company-wide open letter posted in May. “I just had to go; I couldn’t put up with it,” said former Apple Store employee Nicole Turner. “I’m around my older family members on a pretty regular basis and my six-year-old niece… it was just not something I could risk....

While it may not necessarily have been the “golden age” of gaming, the Atari days helped make what the gaming world is today, experts and former Atari diehards say. “I don’t know if I’d say it was the golden age, and I might reserve that for when the Nintendo Entertainment System came out and took gaming to the next level, but I‘d definitely say that the Atari days kicked it off,” said Chris Spear, the host of the podcast, Chefs Without Restaurants, in an email interview with Lifewire....

“The last two years have been a rollercoaster. I keep yelling at all the friends who come back to the stream like, ‘Why are you here?’” Allard said in a phone interview with Lifewire. “I’m still so shocked by this journey every single day. I can’t believe the amount of people who continue to come back and be so supportive.” Humble Beginnings Born and raised in Ottawa, Canada, Allard takes the nice Canadian stereotype and morphs it into reality....

The tech giant is restricting “broad app visibility” to specific apps to provide more security for Android users. While Google’s new policy is a step in the right direction for better security on your device, experts say it is an overall huge win for customer protection. “Users should feel much more secure under Google’s new restrictions,” wrote Ravi Parikh, CEO at RoverPass, to Lifewire in an email. “Google taking a stance about this is a big deal, especially since Android users represent a wide swath of the smartphone user market....
