Roku TV owners have been introduced to a number of annoyances recently through the software update pipeline. There was an arbitration-demanding terms of service that locked your TV until you agreed (or mailed a letter). There is the upcoming introduction of ads to the home screen . But the latest irritation hits some Roku owners right in the eyes.

Reports on Roku's community forums and on Reddit find owners of TCL HDTVs, on which Roku is a built-in OS, experiencing "motion smoothing" without having turned it on after updating to Roku OS 13. Some people are reporting that their TV never offered "Action Smoothing" before, but it is now displaying the results with no way to turn it off. Neither the TV's general settings, nor the specific settings available while content is playing, offer a way to turn it off, according to some users.

"Action smoothing" is Roku's name for video interpolation, or motion smoothing. The heart of motion smoothing is Motion Estimation Motion Compensation (MEMC). Fast-moving video, such as live sports or intense action scenes, can have a "juddery" feeling when shown on TVs at a lower frame rate. Motion smoothing uses MEMC hardware and algorithms to artificially boost the frame rate of a video signal by creating its best guess of what a frame between two existing frames would look like and then inserting it to boost the frame rate.

On Saturday, Turkish police arrested and detained a prospective university student who is accused of developing an elaborate scheme to use AI and hidden devices to help him cheat on an important entrance exam, reports Reuters and The Daily Mail .

The unnamed student is reportedly jailed pending trial after the incident, which took place in the southwestern province of Isparta , where the student was caught behaving suspiciously during the TYT . The TYT is a nationally held university aptitude exam that determines a person's eligibility to attend a university in Turkey—and cheating on the high-stakes exam is a serious offense.

According to police reports, the student used a camera disguised as a shirt button, connected to AI software via a "router" (possibly a mistranslation of a cellular modem) hidden in the sole of their shoe. The system worked by scanning the exam questions using the button camera, which then relayed the information to an unnamed AI model. The software generated the correct answers and recited them to the student through an earpiece.

You can now buy a Starlink satellite dish for $299 (plus shipping and tax) in 28 US states due to a discount for areas where SpaceX's broadband network has excess capacity.

Starlink had raised its upfront hardware cost from $499 to $599 in March 2022 but cut the standard price back down to $499 this week. In the 28 states where the network has what SpaceX deems excess capacity, a $200 discount is being applied to bring the price down to $299. It's unclear how long the deal will last, though we can assume the number of states eligible for $299 pricing will fall if a lot of people sign up.

"In the United States, new orders in certain regions are eligible for a one-time savings in areas where Starlink has abundant network availability," a support page posted yesterday said. "$200 will be removed from your Starlink kit price when ordering on Starlink.com and if activated after purchasing from a retailer, a $200 credit will be applied. The savings are only available for Residential Standard service in these designated regional savings areas."

On Wednesday, Stability AI released weights for Stable Diffusion 3 Medium , an AI image-synthesis model that turns text prompts into AI-generated images. Its arrival has been ridiculed online, however, because it generates images of humans in a way that seems like a step backward from other state-of-the-art image-synthesis models like Midjourney or DALL-E 3 . As a result, it can churn out wild anatomically incorrect visual abominations with ease.

A thread on Reddit, titled, " Is this release supposed to be a joke? [SD3-2B], " details the spectacular failures of SD3 Medium at rendering humans, especially human limbs like hands and feet. Another thread, titled, " Why is SD3 so bad at generating girls lying on the grass? " shows similar issues, but for entire human bodies.

Hands have traditionally been a challenge for AI image generators due to lack of good examples in early training data sets, but more recently, several image-synthesis models seemed to have overcome the issue . In that sense, SD3 appears to be a huge step backward for the image-synthesis enthusiasts that gather on Reddit—especially compared to recent Stability releases like SD XL Turbo in November.

Google's continued abuse of the Fitbit brand is continuing with the shutdown of the web dashboard. Fitbit.com used to be both a storefront and a way for users to get a big-screen UI to sift through reams of fitness data. The store closed up shop in April, and now the web dashboard is dying in July.

In a post on the "Fitbit Community" forums, the company said: "Next month, we’re consolidating the Fitbit.com dashboard into the Fitbit app. The web browser will no longer offer access to the Fitbit.com dashboard after July 8, 2024." That's it. There's no replacement or new fitness thing Google is more interested in; web functionality is just being removed. Google, we'll remind you, used to be a web company. Now it's a phone app or nothing. Google did the same thing to its Google Fit product in 2019 , killing off the more powerful website in favor of an app focus.

Dumping the web app leaves a few holes in Fitbit's ecosystem. The Fitbit app doesn't support big screens like tablet devices, so this is removing the only large-format interface for data. Fitbit's competitors all have big-screen interfaces. Garmin has a very similar website, and the Apple Watch has an iPad health app . This isn't an improvement. To make matters worse, the app does not have the features of the web dashboard, with many of the livid comments in the forums on Reddit calling out the app's deficiencies in graphing, achievement statistics, calorie counting, and logs.

I'm still in the very early stages of poking at macOS 15 Sequoia ahead of our customary review later this fall, and there are quite a few things that aren't working in this first developer beta. Some of those, like the AI features, aren't working on purpose; I am sure some of the iCloud sync issues I'm having are broken by accident.

I've already encountered a few functional upgrades I like, like iCloud support inside of virtual machines , automated window snapping (at long last), and a redesigned AirDrop interface in the Finder. But so far the change that I like the most is actually a new combo wallpaper and screen saver that's done in the style of Apple's Mac operating system circa the original monochrome Mac from 1984. It's probably the best retro Mac Easter egg since Clarus the Dogcow showed up in a print preview menu a couple of years ago.

The Macintosh wallpaper and screen saver—it uses the animated/dynamic wallpaper feature that Apple introduced in Sonoma last year—cycles through enlarged, pixelated versions of classic Mac apps, icons, and menus, a faithful replica of the first version of the Mac interface. Though they're always monochrome, the default settings will cycle through multiple background colors that match the ones that Apple uses for accent colors.

Inhabitants of the ancient Maya city of Chichén Itzá are well-known for their practice of ritual human sacrifice. The most prevalent notion in the popular imagination is that of young Maya women being flung alive into sink holes as offerings to the gods. Details about the cultural context for these sacrifices remain fuzzy, so scientists conduced genetic analysis on ancient remains of some of the sacrificial victims to learn more. That analysis confirmed the prevalence of male sacrifices, according to a new paper published in the journal Nature, often of related children (ages 6 to 12) from the same household—including two pairs of identical twins.

Chichén Itzá ("at the mouth of the well of the Itzá") is located in Mexico's eastern Yucatán. It was one of the largest of the Maya cities, quite possibly one of the mythical capital cities ( Tollans ) that are frequently mentioned in Mesoamerican literature. It's known for its incredible monumental architecture, such as the Temple of Kukulcán ("El Castillo"), a step pyramid honoring a feathered serpent deity. Around the spring and fall equinoxes, there is a distinctive light-and-shadow effect that creates the illusion of a serpent slithering down the staircase. There is also a well-known acoustical effect : clap your hands at the base of the staircases and you'll get an echo that sounds eerily like a bird's chirp—perhaps mimicking the quetzal, a brightly colored exotic bird native to the region and prized for its long, resplendent tail feathers.

The Great Ball Court (one of 13 at the site) is essentially a whispering gallery : even though it is 545 feet long and 225 feet wide, a whisper at one end can be heard clearly at the other. The court features slanted benches with sculpted panels depicting aspects of Maya ball games —which were not just athletic events but also religious ones that often involved ritual sacrifices of players by decapitation.

I enjoyed riding the Tenways CGO800S far more once I stopped thinking of it as a bike, and more like the e-bike version of a reasonable four-door sedan.

It is a bike, to be sure. It has two wheels, handlebars, pedals, and a drivetrain between feet and rear cog. It's just not the kind of bike I'm used to. There are no gears to shift between, just a belt drive and five power modes. The ride is intentionally "Dutch-style" (from a Dutch company, no less), with a wide saddle and upright posture, and kept fairly smooth by suspension on the front fork. It ships with puncture-proof tires, sensible mud guards, and integrated lights. And its 350 W motor is just enough to make pedaling feel effortless, but you'll never quite feel like you're winning a race.

I also didn't feel like I was conquering the road when I was on the CGO800S so much as borrowing my aunt's car for an errand. The "Sky Blue" color helped cement the image of a modern-day Mercury Sable in my head. It's not meant for no-power riding, and its battery isn't a long-hauler, with a stated 53-mile range. It's comfortable, it's capable, and maybe we've long since reached the stage of the e-bike market where some bikes are just capital-F Fine, instead of them all being quirky experiments.

One of the major data brokers engaged in the deeply alienating practice of selling detailed driver behavior data to insurers has shut down that business.

Verisk , which had collected data from cars made by General Motors, Honda, and Hyundai, has stopped receiving that data, according to The Record , a news site run by security firm Recorded Future. According to a statement provided to Privacy4Cars , and reported by The Record, Verisk will no longer provide a "Driving Behavior Data History Report" to insurers.

Skeptics have long assumed that car companies had at least some plan to monetize the rich data regularly sent from cars back to their manufacturers, or telematics. But a concrete example of this was reported by The New York Times' Kashmir Hill , in which drivers of GM vehicles were finding insurance more expensive, or impossible to acquire, because of the kinds of reports sent along the chain from GM to data brokers to insurers. Those who requested their collected data from the brokers found details of every trip they took: times, distances, and every "hard acceleration" or "hard braking event," among other data points.
