WhatsApp iOS to Block Screenshots for ‘View Once’ According to Leaks—When Is it Coming?

Meta and WhatsApp are planning something new for their iOS version, and it is allegedly aiming to block screenshots on photos and videos that were sent via the "View Once" feature. The leaks claim that this feature is coming soon for all iPhone users that utilize WhatsApp, and this update would help them keep confidential or private images only available after the first click of the image. WhatsApp to Block Screenshots for View Once on the iOS WhatsApp debuted the View Once feature for the media sent on devices last year, giving users a chance to control what stays or goes in their conversation with specific individuals. More than a year later, there are now reports regarding the iOS version of WhatsApp blocking the screenshots made to those media, to further protect the sender. According to WABetaInfo, the WhatsApp beta for iOS 22.21.0.71 is showing great promise in delivering this feature for all, particularly as it delivers on blocking screenshots from taking media from View Once messages. It would work on screen recordings as well, as it could be a potential alternative for taking a screenshot on these expiring media.

Google finally fixes the Google Home app with a huge redesign

What you need to know Update (Oct 4, 10:20 am ET): The public preview doesn't actually launch today. We reworked the language in the article to reflect that. Sorry about the confusion. Update (Oct 5, 8:50 am ET): Added information on how to register for the Public Preview program for Android devices. The new Google Home app redesign will be available in the coming weeks for users who want to test it out in a public preview. A brand-new UI is completely customizable and includes helpful new tabs for getting to important areas, like automation, more quickly. Google is implementing Matter Fast Pair, making Google Home available in Wear OS and the web, and migrating important Nest camera features from the Nest app. The last time Google launched a complete redesign to its smart home-centric Google Home app, it was met with a mixed reception. While some users enjoyed the simplicity and clarity of the UI elements, others were irritated with the way it organized information and oversimplified many tasks. Regardless of which camp you were in, the new Google Home app redesign for Fall 2022 should check most (if not all) of the right boxes this time around. If you've got an Android phone with the Google Home app installed, click this link(opens in new tab) from your phone and you should be taken to a signup page to be notified when the preview is available. Some iOS users who were previously enrolled in Google Home app beta programs have already received the new preview program UI. If you're really feeling experimental, APK Mirror(opens in new tab) has an early "dogfooding" build of the new app that can be downloaded and installed, but be warned. This was an early version that was accidentally pushed out to a larger testing group and contains a number of bugs and performance issues. First and foremost is the new UI, which takes some design cues from the previous rebuild and finally gets rid of all the extra white space. In its place is a customizable grid of controls that can be rearranged and regrouped depending on what's most important to you. Google calls these groups Spaces, and they can be used to group the best smart home devices(opens in new tab) by room, by category, or by something more arbitrary like "cat," which Google says could contain your pet cams, cat feeder, vacuum, and air purifier. Live camera streams and lightbulb controls can all reside on the main page now, giving you an instant look at the most important parts of your smart home the second you open the app. Google also says it's finally bringing the most requested Nest Cam features from the old dedicated Nest app over to Google Home, as well, including a brand new camera UI that features better timeline scrubbing, event management, and more. ...

Everything we know about the M2 Pro and M2 Max 14- and 16-inch MacBook Pro

Apple is expected to release the first revision to the 2021 14- and 16-inch MacBook Pro as soon as this month. Here’s everything we expect to see with the M2 Pro chip and M2 Max chip MacBook Pro notebooks so far. Could this be an email? Have you ever had a meeting that you know should have just been an email? That might be happening to the MacBook Pro/iPad Pro event this year. Mark Gurman at Bloomberg has hinted over the last two weeks that Apple is unlikely to hold a second fall event this year. Instead, Apple could simply brief select members of the tech media on the new machines and put out a press release. That’s partly because the big upgrade to these Macs is largely just beefier versions in terms of performance. That doesn’t mean there isn’t a possibility for exterior updates, however. 2022 MacBook Pro colors? Expecting space gray and silver MacBook Pro colors again is the safe bet. Something new has happened since the last round of MacBook Pros, though. In June, Apple made a darker aluminum finish called midnight. The MacBook Air is the only machine to sport this blackish-blue shade of metal so far. If the MacBook Pro came in the new color, it would both look newer and be the first midnight notebook with an all-black keyboard. While many still await an all-black MacBook Pro, this would be a great alternative to silver and space gray. MacBook Pro customers last year were also disappointed that the USB-C MagSafe 3 cable only came in white/silver. It color-matches the silver MacBook Pro, but it’s not a match for space gray customers. Apple has since released color-matching USB-C to MagSafe 3 cables for space gray, starlight, and midnight. Surely, Apple will bundle the space gray version with space gray MacBook Pros with this revision. M2 Pro and M2 Max Finally, the real reason for the upgrade is internal. Apple introduced its M1 Pro and M1 Max processors in October 2021 alongside 14- and 16-inch MacBook Pros. The company kept the Apple silicon upgrade train chugging along last spring with the even more powerful M1 Ultra. Then Apple started the M2 cycle in June with the MacBook Air. We can probably expect the same M1 to M2 performance boost, just scaled up for Pro and Max versions in new MacBook Pros. Yes, that might mean more fan activity to prevent throttling. That’s still to be decided.

Tesla replaces ultrasonic sensors with Tesla Vision on Model 3 & Y vehicles

Tesla is replacing ultrasonic sensors (USS) with Tesla Vision by removing them from its Model 3 and Model Y vehicles. Over the past year, Tesla removed radar from its vehicles as it shifted to Tesla Vision, its camera-based Autopilot system. Tesla explained that the change coincided with the launch of its vision-based occupancy network that’s currently used in Full Self-Driving (FSD) Beta allowing it to replace inputs generated by the software. “With today’s software, this approach gives Autopilot high-definition spatial positioning, longer range visibility, and ability to identify and differentiate between objects. As with many Tesla features, our occupancy network will continue to improve rapidly over time,” Tesla said on its website. During the transition, Tesla Vision vehicles that don’t have USS will be delivered with some features that are either temporarily limited or inactive. This will only be for a short period of time as Tesla transitions its vehicles. The features that will be limited or inactive are: Park Assist: alerts you of surrounding objects when the vehicle is traveling <5 mph. Autopark: automatically maneuvers into parallel or perpendicular parking spaces. Summon: manually moves your vehicle forward or in reverse via the Tesla app. Smart Summon: navigates your vehicle to your location or location of your choice via the Tesla app. Tesla will restore the features once they achieve performance parity through a series of over-the-air software updates. Tesla also expressed confidence in this strategy for the future of Autopilot and safety for its customers. Tesla owners wondering whether or not their vehicle has ultrasonic sensors can look on the front and rear bumpers to see if the 12 sensors are there. Tesla also said that it will continue this rollout with the Model 3 and the Model Y globally over the coming month. Then it will follow up with the Model S and Model X in 2023. In August, Tesla Vision began rolling out to older vehicles with radar through OTA 2022.20.9 just after Tesla FSD Beta 10.69 had been released. Note: Johnna is a Tesla shareholder and supports its mission. Your feedback is important. If you have any comments, or concerns, or see a typo, you can email me at johnna@teslarati.com.

South Korea, U.S. fire missiles to protest 'reckless' North Korean test

SEOUL/UNITED NATIONS, Oct 5 (Reuters) - South Korea and the U.S. military conducted rare missile drills and an American supercarrier repositioned east of North Korea after Pyongyang flew a missile over Japan, one of the allies' sharpest responses since 2017 to a North Korean weapon test. U.S. Secretary of State Antony Blinken warned that nuclear-armed North Korea risked further condemnation and isolation if it continued its "provocations." However, Russia's deputy U.N. envoy told a U.N. Security Council meeting called by the United States that imposing sanctions on North Korea was a "dead end" that brought "zero result," and China's deputy U.N. ambassador said the council needed to play a constructive role "instead of relying solely on strong rhetoric or pressure." North Korea test-fired an intermediate-range ballistic missile (IRBM) farther than ever before on Tuesday, sending it soaring over Japan for the first time in five years and prompting a warning for residents there to take cover. Latest Updates Tear gas, locked gates led to Indonesian soccer stampede, spectators say Pfizer COVID vaccine clears Japan panel for use with young children Bangladesh investigates crippling 10-hour nationwide power cut North Korea fires ballistic missiles as U.S. carrier redeploys Washington called the test "dangerous and reckless," and the U.S. military and its allies have stepped up displays of force. South Korean and American troops fired a volley of missiles into the sea in response, South Korea's Joint Chiefs of Staff said on Wednesday, and the allies earlier staged a bombing drill with fighter jets in the Yellow Sea. The aircraft carrier Ronald Reagan, a U.S. Navy ship that made its first stop in South Korea last month for the first time in years, will also return to the sea between Korea and Japan with its strike group of other warships. The South Korean military called it a "highly unusual" move designed to show the allies' resolve to respond to any threats from North Korea. Speaking during a visit to Chile, Blinken said the United States, South Korea and Japan were working closely together "to demonstrate and strengthen our defensive and deterrent capabilities in light of the threat from North Korea." He reiterated a U.S. call for Pyongyang to return to dialogue, and added: "If they continue down this road, it will only increase the condemnation, increase the isolation, increase the steps that are taken in response to their actions." The U.N. Security Council met on Wednesday to discuss North Korea despite China and Russia telling council counterparts they were opposed to an open meeting of the 15-member body. The top U.S. diplomat for East Asia, Daniel Kritenbrink, accused China and Russia this week of emboldening North Korea by not properly enforcing sanctions. ...

Gas station giants Chevron and Texaco become far more EV friendly

Chevron and Texaco have partnered with Freewire to equip their gas station locations with EV charging solutions. Gas stations have a distinct advantage over other EV charging companies; they are already located everywhere. There are nearly 7000 Chevron gas stations and 8000 Texaco locations in the US alone. And through a new partnership with Freewire, an EV charging infrastructure company, these countless gas stations can now serve as EV charging locations. Freewire’s charging solution is unique. It uses standard wall plug power to charge large batteries within the charger. Then, when an EV hooks up to the charger, the battery charges the vehicle at DC fast charging rates (instead of the wall outlet rate). This saves the location from having to invest in expensive physical charging infrastructure on their site but still allows customers to access DC fast charging. “Our charging stations are helping retail locations like Chevron’s branded stations to enhance their offering to consumers,” said Arcady Sosinov, FreeWire Founder and CEO. “Providing ultrafast, convenient charging at traditional fueling stations can help unlock new customer relationships with EV drivers.” No specific number of chargers or locations were specified in the company press release. Nonetheless, the gas station brands were excited to announce the partnership and that they would be investing billions over the next ten years to electrify their nationwide fueling network. Jesse Love, Chevron’s Retail Brand Experience manager, stated in the press release; “We are committed to investing billions in lower-carbon projects over the next ten years and are excited to join with companies like FreeWire that develop technologies that enhance our retail offerings and can grow our Chevron and Texaco brands.” Gas station companies like Chevron and Texaco are far from the only companies working with Freewire. According to the Freewire website, they also work with brands including Rivian, Walmart, Uber, and other gas station companies like BP to build EV charging infrastructure. Freewire shows that many brands, locations, and companies that have become integral parts of everyday life aren’t going away with the shift to electric vehicles. Gas station brands are now more aware than ever that change is necessary to survive in the future, but how quickly will they build to meet new demand? ...

Samsung's smaller micro-LED 4K TV might finally be on the way to battle OLED

The future of high-end TVs just took another small step towards us. Micro-LED will be the next big technology after OLED and mini-LED TVs, because it delivers all the brightness of LED TVs, but with the per-pixel lighting and contrast of OLED. The best of both worlds… as soon as actual TVs make it into people's homes. Originally, Samsung announced its plans to bring this tech at sizes starting from 76 inches, but only managed to launch one at 110 inches. Then we got word that sizes as small as 76 inches are a few years away at least. However, we then heard that Samsung still planned to get an 89-inch version into production in 2022, which may not be a size the majority of us are looking for, but would be an important sign that progress is being made. And now The Elec reports that Samsung has pulled this off – that an 89-inch microLED 4K TV is under production right now(opens in new tab). This would put it on course for a 2023 launch – we expect that Samsung will announce it at CES 2023, alongside its next-gen mini-LED TVs… and perhaps even the cheaper OLED TVs that reportedly got kicked from 2022's line-up. According to The Elec, Samsung is not moving ahead with production of the 101-inch model it reportedly also planned to launch, at least not yet. There's no word on the final price of this TV, but don't expect it be remotely affordable for us mere mortals, despite the improvements in production. The original given price for the 89-inch model was around $80,000, so even if Samsung has made further cost-saving strides, it's still going to cost around the same as a Mercedes CLS. 90-inch TVs are the new 75-inch TVs All this talk of 89- to 100-inch TVs sounds a bit ambitious even before you get to the price of the micro-LED TV, but very large TVs seem to be the hot ticket right now. LG just launched its first 97-inch OLED TV right alongside Samsung launching a new 98-inch TV that's its brightest ever, for example. Meanwhile, the best 75-inch TVs are growing more and more in popularity – a size that used to feel like it was only for millionaires is now something lots of people with an empty wall and home theater obsession are buying. We expect our guide to the best Black Friday 75-inch TV deals to be one of the biggest this year, because the TV companies have seen which way the wind is blowing too, and you can now find 75-inch TVs for comically low prices during sales events. Which means that the people who want the biggest and best need something even bigger and better, right? So here we are in a world where 100-inch TVs are creeping in more, and we expect more in 2023. The real question is whether Samsung will ever create a micro-LED that's as cool as the folding C SEED N1 TV, based on the same tech…

New asteroid strike images show impact 'a lot bigger than expected'



The James Webb and Hubble telescopes on Thursday revealed their first images of a spacecraft deliberately smashing into an asteroid, as astronomers indicated that the impact looks to have been much greater than expected. The world's telescopes turned their gaze towards the space rock Dimorphos earlier this week for a historic test of Earth's ability to defend itself against a potential life-threatening asteroid in the future. Astronomers rejoiced as NASA's Double Asteroid Redirection Test (DART) impactor slammed into its pyramid-sized, rugby ball-shaped target 11 million kilometers (6.8 million miles) from Earth on Monday night. Images taken by Earth-bound telescopes showed a vast cloud of dust expanding out of Dimorphos—and its big brother Didymos which it orbits—after the spaceship hit. While those images showed matter spraying out over thousands of kilometers, the James Webb and Hubble images "zoom in much closer", said Alan Fitzsimmons, an astronomer at Queen's University Belfast involved in observations with the ATLAS project. James Webb and Hubble can offer a view "within just a few kilometers of the asteroids and you can really clearly see how the material is flying out from that explosive impact by DART", Fitzsimmons told AFP. "It really is quite spectacular," he said. An image taken by James Webb's Near-Infrared Camera (NIRCam) four hours after impact shows "plumes of material appearing as wisps streaming away from the center of where the impact took place", according to a joint statement from the European Space Agency, James Webb and Hubble. Hubble images from 22 minutes, five hours and eight hours after impact show the expanding spray of matter from where DART hit. 'Worried there was nothing left' Ian Carnelli of the European Space Agency said that the "really impressive" Webb and Hubble images were remarkably similar to those taken by the toaster-sized satellite LICIACube, which was just 50 kilometers from the asteroid after separating from the DART spacecraft a few weeks ago. The images depict an impact that looks "a lot bigger than we expected," said Carnelli, the manager of the ESA's Hera mission which intends to inspect the damage in four years.

Woman who allegedly helped arrange migrant flights to Martha’s Vineyard identified by CNN as former

CNN — “Perla,” the woman who allegedly helped arrange migrant flights from Texas to Martha’s Vineyard in Massachusetts, has been identified by CNN as Perla Huerta, who served as a counterintelligence agent and combat medic specialist in the US Army until August. About 50 migrants were flown last month from Texas to Martha’s Vineyard in two planes organized by Florida’s Republican governor as part of his criticism of the federal government’s immigration and border security policies. Attorneys for the migrants have filed a class action lawsuit, saying they were misled in agreeing to the flights after being told they’d arrive to housing, jobs and help with the immigration process; no one on Martha’s Vineyard knew they were coming, local officials have said. A woman named “Perla” offered clothes, food and money to one migrant who had been living on the streets of San Antonio, Texas, in exchange for finding other people who would go on a flight to Massachusetts, the migrant told CNN. The recruiter was unaware of any deception and later felt betrayed by “Perla,” he told CNN. A friend of Huerta confirmed to CNN the woman in a photo provided to CNN by a migrant is Huerta. The New York Times reported other migrants have identified Huerta from pictures taken of her in San Antonio, according to Rachel Self, an attorney who represents the migrants. CNN has reached out to Huerta for comment. Huerta served in the US Army for more than 20 years, US Army spokesperson Madison Bonzo confirmed to CNN. “Perla Haydee Huerta served as a Combat Medic Specialist (68W) and Counterintelligence Agent (35L) in the regular Army from April 2002 to August 2022. She deployed to Iraq from May 2003 to July 2004 and October 2008 to October 2009; Afghanistan from December 2010 to July 2011, September 2014 to January 2015, August 2018 to November 2018 and January 2019 to February 2019; and Djibouti from August 2013 to October 2013,” Bonzo said. “She held the rank of master sergeant at the end of service.” Huerta was discharged in August, the Times reported, citing military records. Florida Gov. Ron DeSantis has disputed the migrants did not know where they were going, saying they had signed a waiver and had been given with a packet with a map of Martha’s Vineyard. “It’s obvious that’s where they were going,” he said, adding it was all “voluntary.” The Sheriff’s Office in Bexar County, Texas, which includes San Antonio, will open an investigation into the flights to see whether any laws were broken, the sheriff has said. Fast food cards and kids’ schooling promised A migrant previously told CNN he had been living on the streets of San Antonio for nearly a month when he met a woman named “Perla” who offered him clothes, food and money in exchange for finding other migrants who’d take Massachusetts-bound flights, he told CNN. ...

M2 Extreme chip in upcoming Mac Pro could get 48-core CPU, 160-core GPU, 384GB RAM

We don’t yet know exactly what Apple has planned for the upcoming Apple Silicon Mac Pro model, but Macworld has been doing some speculating, based on extrapolating from the M1 journey. It suggests that next year might see the release of an M2 Extreme chip, to power a new Mac Pro … Background After years of speculation about Apple dropping Intel chips in favor of its own ARM-based chips for the Mac, we saw the start of that transition in 2020 with the M1 chip in the MacBook Air, 13-inch MacBook Pro, Mac mini, and 24-inch iMac. This was followed in 2021 by the M1 Pro and M1 Max, available in the 14- and 16-inch MacBook Pro models, and then 2022 saw the M1 Ultra which made its debut in the new Mac Studio. July saw Apple begin the cycle again with the next generation of Apple Silicon, the M2 in the all-new MacBook Air. We’re expecting to see new MacBook Pro models perhaps as early as later this month, with M2 Pro and M2 Max chips. It’s been reported that Apple’s array of superlatives doesn’t end at the Ultra, and that we will also see an M2 Extreme chip. M2 Extreme chip Macworld points to the M1 approach of Apple effectively doubling up each chip to form the next one. On this basis, we can extrapolate a likely spec for an M2 Extreme. It suggests that the line-up might look like this: M2: 8-core CPU and 10-core GPU, up to 24GB RAM M2 Pro (predicted): up to 10-core CPU, up to 20-core GPU, up to 48GB RAM M2 Max (predicted): up to 10-core CPU, 40-core GPU, up to 96GB RAM M2 Ultra (predicted): 24-core CPU, 80-core GPU, up to 192GB RAM M2 Extreme (predicted): 48-core CPU, 160-core GPU cores, up to 384GB RAM Bloomberg previously suggested that a slightly more modest 40-core chip was in the works for the upcoming Mac Pro. Codenamed Jade 2C-Die and Jade 4C-Die, a redesigned Mac Pro is planned to come in 20 or 40 computing core variations, made up of 16 high-performance or 32 high-performance cores and four or eight high-efficiency cores. The chips would also include either 64 core or 128 core options for graphics. The computing core counts top the 28 core maximum offered by today’s Intel Mac Pro chips, while the higher-end graphics chips would replace parts now made by Advanced Micro Devices Inc. Apple is also headed toward a 3nm process, which would allow even higher transistor densities, but it’s unclear when these might arrive – though one recent report did suggest that a 3nm process might come to Macs ahead of the iPhone 15. Likely headed for the Mac Pro Whether 40-core or 48-core, it’s likely that the M2 Extreme is destined for the Apple Silicon Mac Pro. This long-awaited machine is expected to land next year. Apple was originally said to have been planning an M1 Mac Pro, but decided instead to wait for the M2 chips. ...

Tesla unveils new Dojo supercomputer so powerful it tripped the power grid

Tesla has unveiled its latest version of its Dojo supercomputer, and it’s apparently so powerful that it tripped the power grid in Palo Alto. Dojo is Tesla’s own custom supercomputer platform built from the ground up for AI machine learning and, more specifically, for video training using the video data coming from its fleet of vehicles. The automaker already has a large NVIDIA GPU-based supercomputer that is one of the most powerful in the world, but the new Dojo custom-built computer is using chips and an entire infrastructure designed by Tesla. The custom-built supercomputer is expected to elevate Tesla’s capacity to train neural nets using video data, which is critical to its computer vision technology powering its self-driving effort. Last year, at Tesla’s AI Day, the company unveiled its Dojo supercomputer, but the company was still ramping up its effort at the time. It only had its first chip and training tiles, and it was still working on building a full Dojo cabinet and cluster, or “Exapod.” Tesla has unveiled the progress made with the Dojo program over the last year during its AI Day 2022 last night. The company confirmed that it managed to go from a chip and tile to a system tray and a full cabinet. Tesla claimed it can replace six GPU boxes with a single Dojo tile, which the company claims costs less than one GPU box. There are six of those tiles per tray. Tesla said that a single tray is the equivalent of “3 to 4 fully-loaded supercomputer racks.” The company is integrating its host interface directly on the system tray to create a big full host assembly: Tesla can fit two of these system trays with host assembly into a single Dojo cabinet. Here’s what the Dojo cabinet looks like closed and opened: That’s pretty much where Tesla is right now as the automaker is still developing and testing the infrastructure needed to put a few cabinets together to create the first “Dojo Exapod.” Bill Chang, Tesla’s Principal System Engineer for Dojo, said: We knew that we had to reexamine every aspect of the data center infrastructure in order to support our unprecedented cooling and power density. They had to develop their own high-powered cooling and power system to power the Dojo cabinets. Chang said that Tesla tripped their local electric grid’s substation when testing the infrastructure earlier this year: Earlier this year, we started load testing our power and cooling infrastructure and we were able to push it over 2 MW before we tripped our substation and got a call from the city. Here’s how the Tesla Dojo Exapod looks opened and closed: ...

Console hacker reveals PS4/PS5 exploit that is “essentially unpatchable”



Longtime console hacker CTurt has blasted what he calls an "essentially unpatchable" hole in the security of the PS4 and PS5, detailing a proof-of-concept method that should allow for the installation of arbitrary homebrew applications on the consoles. CTurt says he disclosed his exploit, dubbed Mast1c0re, to Sony via a bug bounty program a year ago without any sign of a public fix. The method exploits errors in the just-in-time (JIT) compilation used by the emulator that runs certain PS2 games on the PS4 (and PS5). That compilation gives the emulator special permissions to continually write PS4-ready code (based on the original PS2 code) just before the application layer itself executes that code. By gaining control of both sides of that process, a hacker can write privileged code that the system treats as legitimate and secure. "Since we're using the JIT system calls for their intended purpose, it's not really an exploit, just a neat trick," CTurt said of a since-patched JIT exploit on the PS4's web browser. Getting in To get control of the emulator, a hacker can theoretically make use of any number of known exploits that exist in decades-old PS2 games. While some of these can be activated just with button presses, most require using a known exploitable game to access a specially formatted save file on the memory card, leading to a buffer overflow that gives access to otherwise protected memory (similar exploits have been used in PSP and Nintendo 3DS hacks over the years). This method is a bit limited, though, by the fact that the PS4 and PS5 can't natively recognize standard PS2 discs. That means any exploitable game has to be available either as a downloadable PS2-on-PS4 game via PSN or one of the few PS2 games released as physical, PS4-compatible discs via publishers like Limited Run Games. Getting an exploit-ready PS2 save file onto the PS4 isn't a simple process, either. CTurt had to use an already-hacked PS4 to digitally sign a modified Okage Shadow King save file, letting it work with his PSN ID. Then CTurt used the system's USB save import feature to get that file onto the target system. With the basics established, CTurt walks through a complicated series of buffer and stack overflows, memory leaks, and RAM exploits that he used to gain control of the PS2 emulator. With that control established, he was able to access built-in loader functions to transfer a separate PS2 ISO file over a local network, then tell the emulator to load that game via a virtual disc. While loading other PS2 games into an emulator is nice, CTurt's real goal was to use this entry point as a way to run arbitrary homebrew code on the system. That process will be detailed in a future write-up, CTurt tells Ars over Twitter DM, alongside the privilege escalation necessary to run any code "in the context of a PS4 game." ...

Canon R10 review: 4K and fast shooting speeds for less than $1,000



From the moment Canon launched the full-frame mirrorless EOS R, everyone wondered if it would use the same mount for APS-C cameras and effectively kill the EF-M system. It did just that in May, launching not just one but two RF APS-C cameras. One was the flagship $1,500 EOS R7 that I tested last month, and the other is the $980 EOS R10, the subject of today’s review. For that considerably lower price, some features are missing. It has a lower-resolution 24-megapixel sensor versus the R7’s 33 and is missing some of the R7’s highlight features like in-body stabilization and a second card slot. Surprisingly though, it nearly matches the R7 in shooting speeds and offers similar video specs. It also has the benefit of being smaller and lighter for travel, street shooting and more. But technical details aside, how does it perform in the real world, particularly for casual users and beginners? I took it on vacation and did some sports and street shooting to find out. Body and handling Much like with the EF and EF-S lens mounts used on Canon’s DSLRs, the R10 uses the RF-S mount that’s compatible with full-frame RF mount cameras. As such, it supports every full-frame RF lens and also works with the two new RF-S lenses released with the R7 and R10. However, those are only kit lenses, so if you want a prime lens you’ll need to either buy a full-frame lens or use a DSLR EF lens with an adapter. The R10 isn’t as pretty as its rival, the Fujifilm X-T30, but it’s better-looking and easier to use than any of Sony’s boxy APS-C cameras. It’s quite small and light, weighing just 426 grams, considerably less than the 612-gram R7 and just a bit more than the Sony A6400. Despite the small size, it’s got a generous array of physical controls. That includes a pair of dials for exposure, a mode selection dial, a joystick, a D-pad and an AF/M button. You also get a focus selector switch on the front, a record button on top and five programmable buttons across the back and top. Canon didn’t try anything fancy here as it did with the touch control on the EOS-R, and everything is easy to find, particularly if you’re used to Canon cameras. The grip is deep, though your fingers can get cramped with a large lens installed. The menus are typical Canon, so they don’t exactly have a fresh modern look, but they’re easy to use.

Sony's $1,000 Xperia 5 IV offers 4K 120p HDR on all three rear cameras



Sony has unveiled a smartphone with both gaming and photo-taking powers that's (a bit) less expensive than its last few models. The Xperia 5 IV comes with a Snapdragon 8 Gen 1 Mobile Platform and 120Hz 6.1-inch 21:9 OLED display, while offering photo features from the Xperia 1 IV flagship like real-time eye AF and real-time tracking on all three rear cameras. Taking advantage of its strong reputation in photography with models like the Alpha A7 IV, Sony is pitching the Xperia 5 IV as a content creation device. To that end, it comes with no less then four 12-megapixel cameras with three on the back (a 16mm 1/2.5-inch f/2.2 ultra-wide, 24mm f/1.7 1/1.7-inch wide and 60mm f/2.4 1/3.5-inch portrait) and one up front for selfies (1/2.9-inch). The real-time eye AF promises that your subjects' eyes rather than their nose will stay in focus, and the real-time AI-powered tracking feature keeps fast-moving subjects in focus. It supports shooting speeds of 20 fps with AF and auto exposure for all lenses. The relatively large pixels (1.9 microns) on the main camera should allow for decent low-light shooting, too. All three rear sensors have 120fps read-out speeds, letting you record 4K HDR at up to 120fps. Sony is also promising 4K HDR with "outstanding contrast grading" and the ability to take selfies or vlog in high glare or dark environments. As with the Xperia I IV, it comes with the Videography Pro feature that lets you livestream your content to YouTube and other streaming services. The screen looks to be up to the job for creators as well. It's HDR10 capable (though doesn't support Dolby Vision) and supposedly 50 percent brighter than the last model. It also offers something called "Real Time HDR Drive" that can increase image quality by filling in details on over- and underexposed shots. Users of Bravia Core will also be able to access Sony's latest releases and classic films. On the gaming side, the 120Hz display should allow for smooth gaming, and a 240Hz touch scanning rate allowing for rapid inputs. The Plus Game enhancer lets you customize picture and sound, and it offers live streaming on Sony's Social Networking Service (SNS), with high-frame recording up to 120fps. You can use it to check viewer's comments in real time and implement game commentary. On the audio side, it supports both Dolby Atmos and Sony's 360 Reality audio, either via a wired 3.5mm jack or wireless Bluetooth LE. Other features include a 5,000mAh battery, 8GB of RAM, 128GB of memory and 5G capabilities. The Xperia 5 IV will be available at the end of October 2022 for $1,000 in black or a green color variation. If you pre-order via Sony's website or B&H Photo starting today at 11AM ET, you'll be eligible to receive the WF-1000XM4 wireless earbuds, a $280 value.

Lenovo’s Glasses T1 let you bring a private big screen display with you



Lenovo is the latest company promoting a USB-C monitor made for your face. The company’s new Glasses T1 put a Full HD OLED screen in front of each of your eyes and were revealed today during IFA and on Lenovo’s virtual showcase. This wearable private display, as Lenovo puts it, is very much like other consumer smart glasses, including TCL’s NxtWear Air, which puts two 1080p micro-OLED screens in front of your eyes, just like Lenovo’s T1. Another similar product is the Nreal Air, though that one has a 90Hz screen refresh rate compared to the T1’s 60Hz. You aren’t getting any VR or AR experiences with these types of glasses, and you can’t safely walk around wearing them as your vision would be entirely obscured, and the cable keeps them tethered to whatever your source is. Instead, it’s designed for you to stay put as if you were watching an actual TV or monitor, but the effect makes it feel like a huge theater screen. You can watch movies, play games, and do your confidential digital paperwork, all while looking like Marvel’s Daredevil — without his hyper-awareness. Lenovo is betting that mobile gamers will want these glasses, too, citing a Global Industry Analysts report that predicts a $160 billion global market for that industry by 2026. Similarly, it’s expecting the eclipsing video streaming market to mean more people might want to watch shows inside their own T1 bubbles. The Glasses T1 use a physical wire to connect to devices like PCs, tablets, smartphones, Macs, and other devices that can output video through USB-C. If you’d like to use the glasses with iOS devices like your iPhone, you’ll have to buy Lenovo’s HDMI adapter, as well as Apple’s Digital AV adapter — all because Apple still hasn’t moved on from its 10-year-old Lightning port. The T1 glasses also work with Motorola’s secondary “Ready For” interface that lets you use apps in a desktop style. ...
