Ugandan researchers have developed inexpensive air quality monitoring sensors that work in extreme conditions. The sensors could let Uganda and other countries switch from pricey imported monitors. It’s part of a growing effort to develop a broader network of air quality monitors. “Many individuals in developing countries are unable to afford even low-cost air quality monitors and are thus unable to determine air pollution levels in their neighborhood,” Akshaya Jah, a professor of economics and public policy at Carnegie Mellon University, told Lifewire in an email interview....

“I like helping people, I like seeing things click for people, I like seeing them grow, and I like seeing them learn. That’s been there for as long as I can remember,” Rue said in a phone interview with Lifewire. “It was a passion, but I never dreamed it would become something primary—actually, I dreamed it, but I never imagined it would come true, especially in this space.” Rue has only recently seen success from their content on the platform, but their presence is far from new....

LG’s new DualUp monitors look like two monitors stacked on top of each other. Dual monitors aren’t new—they’re a great way to see more apps and windows at once—but usually, we put them side by side. Meanwhile, some media professionals prefer a vertical screen, although that’s certainly a minority case. But one look at LG’s new designs can make one wonder: why don’t we all use square screens? “The 4:3 aspect ratio of old televisions and computer monitors was so common that once HD and 4K became the norm, we didn’t want to look back....

Even Spotify’s music recommendations are a form of AI. Machine Learning Many of the innovations we rely on today function through a branch of AI known as machine learning (ML)....

This revamped Chromecast is a far cry from the $35 streaming stick that first hit stores in 2013. The new refresh adds an updated user interface and throws in a remote control for good measure. Noticeably missing, though, is a way to access Apple TV content. “The addition of Google TV and remote control to the latest Chromecast is a game-changer for cord-cutters,” Brett Atwood, an associate professor at Washington State University who focuses on new consumer and entertainment technology trends, said in an email interview....

Flowrite is a new AI tool that promises to turn simple instructions into a fully-fledged email. The software can be used as a web app or browser extension, and it’s one of a growing number of AI tools for everyday users. “AI can take the drudgery out of many tasks so humans can focus on more strategic objectives,” Sam Zheng, CEO of AI software company DeepHow, told Lifewire in an email interview....

What Is an Email Username? The username identifies a specific person or address in a domain. Whoever sets up your email address (you, your school, or your employer) selects the username. When you sign up for a free email account, for example, you can pick a creative username of your own. Usernames used in a professional capacity usually employ a standardized format. For example, a company might use your first name, such as Bill@example....

What Is a PBM File? A file with the PBM file extension is a Portable Bitmap Image file. This isn’t nearly as common a format as PNG, JPG, GIF, and others you’ve probably heard of. One big difference is that these are text-based, black and white images that contain either a 1 for a black pixel or a 0 for a white pixel. How to Open a PBM File PBM files can be opened with Inkscape, XnView, Adobe Photoshop, Netpbm, ACD Systems Canvas X Draw, Corel PaintShop Pro, and probably several other photo and graphics tools as well....

The service was originally marketed to budget-conscious college students, which makes it an attractive choice for cord-cutters looking to reduce their monthly television bills....

The Viewer The viewer is nothing special, but it does the job. It gives you a standard thumbnail view, along with a folders list on the side, and a larger preview window, plus a few functions for rotating images, viewing EXIF data, and so on. The maximum thumbnail size is pretty small, and there does not seem to be any sorting options. Each of the other tabs in PhotoScape has its thumbnail browser as well, so you probably won’t use this tab often....

The Plantronics Voyager 4220 UC is a professional Bluetooth headset with a few extra bells and whistles.

Design and Durability: Portable but unmemorable The Quntis PD Fast Charger and Cable is small and portable, thanks to the Velcro strap that makes for easy and neat folding and travel. There’s no wow factor to the look of this product, however, and that is underscored by some weird fit issues. The USB-C head fits very snugly into the PD port, but almost to a fault. I had to really pull the cable when removing it from the power adapter....

Reddit recently announced the success of a new content policy it unveiled in June. Designed to combat hateful content on the platform, the update provides strict guidelines to regulate hate speech, which culminated in the removal of nearly 7,000 subreddits. The company is celebrating an 18 percent drop in hateful content since the policy rework. However, while Reddit rejoices, users are still experiencing a special kind of abuse on the platform....

But are there really problems that build up in the registry that need fixing? Are registry cleaners the solution to most of my computer issues? What does a registry cleaner actually do? The short answer is no, there are few real “registry problems” that a registry cleaner/repair/fix-it tool can actually solve. So why are there so many of these programs?! They do have a purpose, but few actually have anything to do with the registry anymore....

With that savings comes a number of tradeoffs, including fewer channels, no sports or news, and fewer devices and services that let you access the service. Overall Findings The biggest difference between Sling TV and Philo, aside from the higher price for Sling TV, is the flexibility. Sling TV offers two plans with a different mix of channels tailored for people who prefer ESPN (Orange) to NBC Sports or Fox Sports (Blue), and if you want access to lifestyle channels like USA, TLC, or BET (Blue)....

Cybersecurity researchers are alarmed by the attack but not surprised by attackers refining their techniques. “Cybercriminals are constantly updating their attacks to try to avoid detection and, ultimately, achieve their aims,” Jack Chapman, VP of Threat Intelligence at Egress, told Lifewire over email....

Personalization is the core theme of the update—it is “designed for you”—and many of the new features are centered around providing a deeply personal experience to Android users. Some notable features are the redesigned systems spaces, a fully adaptable quick settings shade, and a user privacy dashboard. While not all of the new features have been revealed, and there may be dozens more, these are the ten best we’ll see in Android 12....
