Qualcomm’s new Snapdragon 4100 features much-needed improvements for the next Wear OS watches

Qualcomm is announcing two new Wear OS processors today, the Snapdragon Wear 4100 Plus and the Snapdragon Wear 4100, the first major updates to its smartwatch platform since 2018. Qualcomm claims the new chips will have vastly improved speed, with a “significantly faster new processor,” and big jumps in performance for the GPU, memory, camera, and overall battery life.

They’re big promises, but put simply, Google’s Wear OS badly needs this kind of hardware overhaul. The last major revision to the Snapdragon Wear lineup, the Snapdragon Wear 3100, was a minor update to 2016’s Snapdragon 2100. In fact, given that the 2100 and 3100 have the exact same main processor, the debut of the 4100 marks the first concrete speed improvements for Wear…

Fortnite finally leaves early access as Epic slows down Save the World development

See the original posting on The Verge

Fortnite’s iconic Battle Royale game mode took the world by storm, and today, Epic Games has announced that it’ll finally be removing the early access label from both the free-to-play shooter and the less popular original Save the World mode. Epic also announced that Save the World will continue to be a paid title separate from the free-to-play Battle Royale, and with the “official” launch, it’ll start slowing down the release of content for Save the World.

The early access label for Fortnite is actually a holdover from when Epic Games first released Save the World back in May 2017 as a paid early access title — but it’s persisted on all versions of Fortnite until now, despite that it’s perhaps the most popular game in the world right…

Samsung has introduced the next generation of its QVO lineup of high-capacity consumer solid-state drives: the 870 QVO. It will be available starting on June 30th from Samsung and other retailers, and you’ll be able to choose from a few different storage configurations.

The 870 QVO starts with 1TB at $129.99, moving up to 2TB of storage for $249.99 and $499.99 for the 4TB model. If you churn through a lot of data, you might be interested in the 8TB option that will be available in August, which is the first of this capacity Samsung has created. The price for the 8TB option isn’t public yet, though a leak on Amazon picked up earlier this month by Tom’s Hardware indicates it might cost $900 and release on August 24th.

Apple’s second-generation AirPods that include a wireless charging case cost $170 if you buy them new, but Best Buy is offering a very good deal on refurbished models if you want to save another $60. This refurbished set of second-generation AirPods is $110, the best price we’ve seen yet, and they come with all of the original accessories. If you want to charge them wirelessly, you’ll need to use a wireless charger you already own or pick one up for less than $20.

Best Buy claims that they are tested, though your mileage may vary in terms of whether there are scratches on the charging case. These are covered with a 90-day warranty through Best Buy. While that’s nowhere near as good as the one-year coverage you’ll get with buying a new…

Pop-up wearable tent for COVID-19 protection in offices, schools, and medical facilities

See the original posting on Boing Boing

A few years back, my brother Rick Pescovitz came up with Under The Weather Pods, single-person pop-up shelters. (You may have caught Rick on Shark Tank.) Rick was sick of getting soaked at his kids’ soccer games and was inspired by a portable toilet he saw by the field. Under The Weather Pods are designed for watching sports, fishing, and other outdoor events where it’s raining, windy, or cold, but you are either obligated to watch or having so much fun you don’t want to leave.

When the pandemic began, my brother quickly made two new designs for hospitals and healthcare workers: The IntubationPod is a pop-up shield for medical procedures involving the head and neck area. It’s apparently much less expensive than the rigid plastic boxes that are commonly used during intubation. Meanwhile, the ShieldPod enhances protection for physicians and nurses as they move through medical facilities treating patients. Both devices are now in use at several hospitals around the country. I’m proud of my brother Rick and his wife Kelly who is president of Under the Weather!

Schools, businesses, and air travelers are now reaching out to Rick about the ShieldPod for use in classrooms, office settings, and on flights. Stay safe everyone.

Legendary comedian Carl Reiner, RIP

See the original posting on Boing Boing

Legendary comedian, actor, writer, and director Carl Reiner has died at age 98. Reiner is best known for performing with Sid Caesar and Imogene Coca on the 1950s TV variety program Your Show of Shows and later creating The Dick Van Dyke Show. He also directed George Burns in the classic “Oh God!” (1977), Steve Martin in “The Jerk” (1979) and acted in movies and TV shows like “Ocean’s Eleven” (2001), “Parks and Recreation,” and “House.” From the New York Times:

As part of a stellar supporting cast that also included Imogene Coca and Howard Morris, Mr. Reiner proved his versatility week after week on “Your Show of Shows,” which ran from 1950 to 1954 on NBC and established the template for sketch comedy on television. He played everything from a harried commuter to a frenzied rock ’n’ roller to an unctuous quiz-show host. But he is probably best remembered as an interviewer, solemnly posing questions to a mad professor, a spaced-out jazz musician or some other over-the-top character played by Mr. Caesar, and adding to the humor simply by being serious.

Mr. Reiner contributed behind the scenes as well. He took part in the frenzied writing sessions that shaped the show, bouncing jokes off the walls of the writers’ room with the likes of Mr. Brooks and Neil Simon.

“I became a writer because of that room,” he recalled. “I’d say something and somebody would yell: ‘What do you know? You’re not a writer.’ So I became a writer.”

Motorola’s unlocked Edge gets a $700 price tag, slight spec bump

See the original posting on The Verge

Motorola has announced that the regular Edge — the cheaper sibling to its recently released flagship Edge Plus — will cost $699.99, which puts it at $300 less than the $999.99 Edge Plus. There’s still no release date, though, outside of the previously announced “summer” window.

Motorola has also announced that it’ll bump up the specs a bit for the standard Edge. Instead of the originally planned 4GB of RAM and 128GB of storage, the Edge will now offer 6GB of RAM and 256GB of storage.

The Motorola Edge features a similar design to the Edge Plus — including the eponymous 6.7-inch “edge” display — but it achieves that cheaper price point by cutting down on some of the specs. The Snapdragon 865 on the Edge Plus is replaced with a slightly…

Google now lets you see dinosaurs in the real world through augmented reality

It’s one thing to read about the massive dinosaurs that used to roam the Earth; it’s quite another to imagine how they’d look stomping around your neighborhood. Google can help, though. The company has added 10 augmented reality dinosaurs to Google search, meaning that next time you’re looking for vital statistics on a Brachiosaurus or Pteranodon, you’ll also be able to get an idea of how these creatures looked in real life.

Google started adding augmented reality animals to searches last year at Google I/O and has since introduced a veritable menagerie, covering cats, scorpions, bears, tigers, and many more. Now, a herd of dinosaurs has also been added to this list, each of which uses graphics developed for the Jurassic World Alive…

OnePlus confirms its upcoming cheaper phones will be called Nord

See the original posting on The Verge

OnePlus has announced a new product line of cheaper phones called OnePlus Nord, with the goal of making the “premium OnePlus experience accessible to more users.”

“We are immensely proud of our flagship products and will continue to create more tech-leading flagships for our users. Now we are excited to share the OnePlus experience with even more users around the world through this new product line,” commented OnePlus CEO Pete Lau in the announcement.

OnePlus originally began by selling cheaper devices (the original OnePlus One started at just $299), but it’s become best known for its premium smartphones over the past few years (like the current OnePlus 8 and 8 Pro). Those models have attempted to challenge phones from more entrenched…

Top YouTube influencers canceled

See the original posting on Boing Boing

Taylor Lorentz is chronicling internet drama brilliantly for the New York Times, and her latest report is on the quasi-downfall of two high-flying YouTubers, Shane Dawson and Jeffree Star. They exemplify the stereotype of YouTube influencers–vacuous narcissists, tireless producers, canny businessmen–facing ruin after years of attention-seeking at the borders of racism, sexism and general abuse. The internet is a permanent record and the ground is liquefying underfoot.

Dawson has racked up billions of views on YouTube, often by engaging in offensive humor. He has posted several videos in blackface, mocked those with disabilities, joked about bestiality, sexualized minors, and once spoke about “figuratively murdering someone.” On June 26, Mr. Dawson posted a teary apology to his channel, in which he tried to make amends for his past, declaring that he deserved to “lose everything.”

No sooner had his apology video posted than a clip of him pretending to sexually gratify himself to a photo of Willow Smith, then 11 years old, resurfaced and began to get shared widely.

That’s just one of the most ostentatiously repulsive acts. The catalog of backstabbing, blackmail, and insider grossness is quite extensive and Lorentz packs in the links for anyone wanting to take a deep dive. What I like most about her work at the Times is how it illustrates a growing dissatisfaction at what social media companies actually did to the internet. They reinstituted the old hierarchies, then stocked them with all these perma-adolescent psychos.

YouTube’s tolerance for abuse caused two knock-on problems: YouTube (especially its comment platform) was ignored by media except as a video hosting site, the culture growing there was ignored as a result, and the people emerging from that culture were (temporarily, it turns out) able to quietly ignore their own earlier work after gaining broader exposure.

Vizio’s latest 4K HDR TVs now shipping, with OLED model due in the fall

First announced back at CES, Vizio’s latest lineup of 4K TVs is starting to roll out to retailers. The company’s first OLED model will take a little longer and isn’t expected to ship until the fall, however. Still, the other sets in the 2020 family — Vizio is confusingly calling it the 2021 lineup for some reason — should offer excellent picture quality and be near the top of your list if you’re planning to upgrade your TV for the PlayStation 5 or Xbox Series X this holiday.

As before, the flagship LED remains the P-Series Quantum X, which can hit up to 3000 nits of peak brightness and comes in 65 ($1,499.99), 75 ($1,999.99), and 85-inch ($2,999) sizes. Vizio says the entire panel can reach up to 800 nits of brightness. The standard…

The ThinkPad TrackPoint tried to build a better mouse

See the original posting on The Verge

In today’s digital age, it sometimes feels like hardware has taken a back seat to the software that drives our devices. Button of the Month will look at what some of those buttons and switches are like on devices old and new to appreciate how we interact with them on a physical, tactile level.

It goes by many names: the TrackPoint, the nub, the mouse nipple, the pointing stick, the weird red dot on your keyboard. Love it or hate it, the famous — or infamous — mouse solution has practically become the symbol for ThinkPad’s business-focused laptops. It’s a well thought out, but ultimately failed alternative to the now-ubiquitous trackpad. But there’s an argument to be made that it might actually be a better form of mouse for laptops, as…

Several software features from Samsung’s unannounced Galaxy Watch 3 have leaked, after the smartwatch’s firmware was downloaded early by XDA-Developers’ Max Weinbach. According to Weinbach’s sleuthing, Samsung’s unannounced smartwatch could include more customizable watchfaces, alongside updates to its music, email, and calendar apps.

Watchfaces are seeing some of the biggest software changes. Weinbach says there are new designs to choose from, and some of these will include a feature called “informative digital edge,” where custom details like your heart rate or current steps can be shown around the edges of the watchface.
