Microsoft Readies 'Next-Gen' AI-Focused PCs

Slashdot - Thu, 2023-12-28 23:10
Microsoft is working on significant updates to its Surface Pro and Surface Laptop lines. According to Windows Central, new devices "will be announced in the spring and will be marketed as Microsoft's first true next-gen AI PCs." From the report: For the first time, both Surface Pro and Surface Laptop will be available in Intel and Arm flavors, and both will have next-gen NPU (neural processing unit) silicon. Sources are particularly excited about the Arm variants, which I understand will be powered by a custom version of Qualcomm's new Snapdragon X Series chips. Internally, Microsoft is calling next-generation Arm devices powered by Qualcomm's new chips "CADMUS" PCs. These PCs are purpose-built for the next version of Windows, codenamed Hudson Valley, and will utilize many of the upcoming next-gen AI experiences Microsoft is building into the 2024 release of Windows. Specifically, Microsoft touts CADMUS PCs as being genuinely competitive with Apple Silicon, sporting similar battery life, performance, and security. The next Surface Pro and Surface Laptop are expected to be some of the first CADMUS PCs to ship next year in preparation for the Hudson Valley release coming later in 2024. So, what's changing with the Surface Laptop 6? I'm told this new Surface Laptop will finally have an updated design with thinner bezels, rounded display corners, and more ports. This will be the first time that Microsoft's Surface Laptop line is getting a design refresh, which is well overdue. The Surface Laptop 6 will again be available in two sizes. However, I'm told the smaller model will have a slightly larger 13.8-inch display, up from 13.5 inches on the Surface Laptop 5. Sources say the larger model remains at 15-inches. I'm told Surface Laptop 6 will also have an expanded selection of ports, including two USB-C ports and one USB-A port, along with the magnetic Surface Connect charging port. Microsoft is also adding a haptic touchpad (likely with Sensel technology) and a dedicated Copilot button on the keyboard deck for quick access to Windows Copilot. The next Surface Pro is also shaping into a big update, although not as drastic as the Surface Laptop 6. According to my sources, the most significant changes coming to Surface Pro 10 are mostly related to its display, which sources say is now brighter with support for HDR content, has a new anti-reflective coating to reduce glare, and now also sports rounded display corners. I've also heard that Microsoft is testing a version of Surface Pro 10 with a slightly lower-resolution 2160 x 1440 display, down from the 2880 x 1920 screen found on previous Surface Pro models. Sources say this lower-resolution panel is only being considered for lower-tier models, meaning the more expensive models will continue to ship with the higher-resolution display. Lastly, I also hear Microsoft is equipping the next Surface Pro with an NFC reader for commercial customers and a wider FoV webcam, which will be enhanced with Windows Studio Effects. It should also be available in new colors. I've also heard we may get an updated Type Cover accessory with a dedicated Copilot button for quick access to Windows Copilot.

Researchers Come Up With Better Idea To Prevent AirTag Stalking

Slashdot - Thu, 2023-12-28 22:33
An anonymous reader quotes a report from Ars Technica: Apple's AirTags are meant to help you effortlessly find your keys or track your luggage. But the same features that make them easy to deploy and inconspicuous in your daily life have also allowed them to be abused as a sinister tracking tool that domestic abusers and criminals can use to stalk their targets. Over the past year, Apple has taken protective steps to notify iPhone and Android users if an AirTag is in their vicinity for a significant amount of time without the presence of its owner's iPhone, which could indicate that an AirTag has been planted to secretly track their location. Apple hasn't said exactly how long this time interval is, but to create the much-needed alert system, Apple made some crucial changes to the location privacy design the company originally developed a few years ago for its "Find My" device tracking feature. Researchers from Johns Hopkins University and the University of California, San Diego, say, though, that they've developed (PDF) a cryptographic scheme to bridge the gap -- prioritizing detection of potentially malicious AirTags while also preserving maximum privacy for AirTag users. [...] The solution [Johns Hopkins cryptographer Matt Green] and his fellow researchers came up with leans on two established areas of cryptography that the group worked to implement in a streamlined and efficient way so the system could reasonably run in the background on mobile devices without being disruptive. The first element is "secret sharing," which allows the creation of systems that can't reveal anything about a "secret" unless enough separate puzzle pieces present themselves and come together. Then, if the conditions are right, the system can reconstruct the secret. In the case of AirTags, the "secret" is the true, static identity of the device underlying the public identifier that is frequently changing for privacy purposes. Secret sharing was conceptually useful for the researchers to employ because they could develop a mechanism where a device like a smartphone would only be able to determine that it was being followed around by an AirTag with a constantly rotating public identifier if the system received enough of a certain type of ping over time. Then, suddenly, the suspicious AirTag's anonymity would fall away and the system would be able to determine that it had been in close proximity for a concerning amount of time. Green notes, though, that a limitation of secret sharing algorithms is that they aren't very good at sorting and parsing inputs if they're being deluged by a lot of different puzzle pieces from all different puzzles -- the exact scenario that would occur in the real world where AirTags and Find My devices are constantly encountering each other. With this in mind, the researchers employed a second concept known as "error correction coding," which is specifically designed to sort signal from noise and preserve the durability of signals even if they acquire some errors or corruptions. "Secret sharing and error correction coding have a lot of overlap," Green says. "The trick was to find a way to implement it all that would be fast, and where a phone would be able to reassemble all the puzzle pieces when needed while all of this is running quietly in the background." The researchers published (PDF) their first paper in September and submitted it to Apple. More recently, they notified the industry consortium about the proposal.

Retailers To Pay For Consumers' E-waste Recycling From 2026 Under UK Plans

Slashdot - Thu, 2023-12-28 21:20
British households will benefit from improved routes for recycling electronic goods from 2026, under government plans to have producers and retailers pay for household and in-store collections. From a report: Consumers would be able to have electrical waste (e-waste) -- from cables to toasters and power tools -- collected from their homes or drop items off during a weekly shop, the Department for Environment, Food and Rural Affairs (Defra) said in a consultation published on Thursday. The ambition is for retailers, rather than the taxpayer, to pick up the tab for these new ways of disposing of defunct, often toxic products safely. The measures are due to come into force in two years' time. Almost half a billion small electrical items ended up in landfill last year, according to data from the not-for-profit Material Focus. This problem was particularly acute during Christmas, when 500 tonnes of Christmas lights were thrown away, the government said. [...] Measures aimed at easing the problem of electronic waste now include requiring larger retailers to create "collection drop points for electrical items in-store" for free, and without the need to exchange this with a new purchase. From 2026 onward, bricks-and-mortar retailers and online sellers would have to collect any broken or rejected large electrical goods including fridges or cookers when they are delivering a replacement product, Defra said.
