Apples M3 MacBook Air combines Apples lightest and thinnest laptop design with the impressive horsepower of third-generation Apple silicon. B&H Photo Video has the 2024 laptop on sale for $200 off. Usually $1,299, the variant with 16GB of RAM and 256GB of storage is only $1,099. The 2024 MacBook Air adds the M3 chip, Apples silicon with a 3nm process that crams more electronic components into a smaller space compared to its predecessor. Apples Neural Engine, which will become more crucial with the introduction of Apple Intelligence AI features this fall, is also 15 percent faster in the M3 family than the M2. While the M3 MacBook Air may not provide a dramatic speed boost over the M2 in day-to-day tasks, it has a higher ceiling for intensive work and is more future-proofed. The M3 model adds support for dual screens with the lid closed. It also supports Wi-Fi 6Es faster speeds and lower latency if you have a compatible router. Engadget Senior Editor Devindra Hardawar praised the device in his review from earlier this year, describing the two sizes of the laptop as great computers with excellent performance, gorgeous screens and incredible battery life. The M3 MacBook Air lasted over 10 hours in our video-playback battery stress test. Although the $200 off deal at B&H is for the 13-inch model, the retailer (which operates online but also has a robust Manhattan retail outlet) has the 15-inch model for $150 off. If you like more real estate for your apps and desktop (or, like me, need larger text for aging eyes), the larger model may be the better choice. One thing to keep in mind before ordering is that B&Hs return policy states that it wont take computers back for a refund once the packaging has been unsealed. Although you can contact customer service for an exchange if something is wrong out of the box, buyers remorse alone wont cut it for getting your money back. This contrasts with competitors like the Apple Store, Amazon and Best Buy, so consider that before proceeding. However, apart from that footnote, B&H has been an Apple partner for nearly a decade and has built a solid reputation with customers since its 1973 founding.

There's word going around that X just enabled a setting that lets it train Grok on public tweets, as well as any interactions they have with the chatbot. That's not entirely true: a help page instructing users how to opt-out of X using their data to train Grok has been live since at least May. X just never exactly made it crystal clear that it was opting everyone into this, which is a sketchy move. If you don't want a bad chatbot to use your bad tweets for training, it's thankfully easy to switch that off. You just need to uncheck a box from the Grok data sharing tab in the X settings. If that link doesn't work, you can go to Settings > Privacy and Safety > Grok. For the time being, the setting isn't accessible through X's mobile apps (the company says it will be soon), so you'll have to uncheck the box on the web for now. It's also worth noting that Grok isn't trained on any tweets from private X accounts. All X users have the ability to control whether their public posts can be used to train Grok, the AI search assistant. This option is in addition to your existing controls over whether your interactions, inputs, and results related to Grok can be utilized. This setting is Safety (@Safety) July 26, 2024 One of X's selling points for Grok when it rolled out the chatbot was that it had the advantage of using real-time information that's published on the platform in other words, users' tweets. That only works if users opt-in or are automatically enrolled into sharing their data with the chatbot. But X isn't exactly the pinnacle of truth and accuracy. It's full of pranksters, and lifting their jokes might be one of the reasons why Grok keeps on getting stuff wrong. In any case, it's not exactly uncommon for AI models to be trained on material without explicit permission from the original creators.This article originally appeared on Engadget at https://www.engadget.com/heres-how-to-stop-groks-ai-models-using-your-tweets-for-training-161041266.html?src=rss

As we've seen in years past, once Amazon's Prime Day ends, many of the deals evaporate. But one week after the sale frenzy (both from Amazon and other retailers) we're still seeing quite a few deals that have either stayed true to their event pricing or have come up with a fresh discount after the fact. Right now, the budget pick in our iPad guide is just $1 more than the low it hit last week. Our favorite pair of budget earbuds is also just a buck more than the Prime Day low. And, as of this writing, Amazon is still offering a free $300 gift card if you order the new Samsung Galaxy Z Fold 6 that just started shipping on Wednesday. Here are the best tech deals from this week that you can still get today. Follow @EngadgetDeals on Twitter and subscribe to the Engadget Deals newsletter for the latest tech deals and buying advice.

The 65-inch LG C3 OLED TV is 48 percent off via Woot, which brings the price down to $1,298. Thats a savings of around $1,200 on the well-regarded OLED panel. Theres one major caveat. This deal is for today only, or until the stock runs out. To that end, theres a limit of one per customer, but thats probably not a huge deal unless youre in the process of furnishing a mansion or something. The LG C3 OLED is considered one of the best TVs for gaming, and with good reason. We loved this televisions high contrast and the deep blacks on offer. We also praised the low input lag, increased motion response and wide array of appropriate viewing angles. It follows HDR guidelines, works with all the major VRR formats and has four HDMI 2.1 ports that are capable of outputting 4K 120Hz with a gaming console or PC. It supports all the major HDR standards, including Dolby Vision. This TV is available in sizes up to 83-inches, but the larger models arent on sale. I use a 65-inch OLED, though not this one, and its plenty big enough for TV and gaming. Despite being a dang good value, this isnt a perfect television. The WOLED panel doesnt get quite as bright as a QD-OLED like the Samsung S90C. Also, it doesnt support a 144Hz refresh rate, which could be a dealbreaker to picky PC gamers. Still, the price is definitely right. Just make sure you pick this up sooner rather than later.

NASA's Perseverance rover has been collecting samples from Mars since 2021, but one of its most recently collected rocks could help it achieve its goal of finding evidence of ancient life on the planet. Nicknamed Cheyava Falls after the tallest waterfall in the Grand Canyon, the 3.2 feet by 2 feet sample contains "chemical signatures and structures" that could've been formed by ancient microbial life from billions of years ago. Perseverance collected the rock on July 21 from what was once a Martian river valley carved by flowing water long ago. The sample, which you can see in close up below and from afar at the center of the image above, exhibits large white calcium sulfate veins running along its length. They indicate that water did run through the rock at one point. More importantly, it contains millimeter-size marks that look like "leopard spots" all over its central reddish band. On our planet, those spots could form on sedimentary terrestrial rocks when there are chemical reactions that turn hematite, one of the minerals responsible for Mars' reddish color, to white. Those reactions can release iron and phosphate, which could've served as an energy source for microbes. The rover's Planetary Instrument for X-ray Lithochemistry (PIXL) tool already determined that the black rings around the spots contain iron and phosphate. However, that doesn't automatically mean that the rock truly did serve as a host for ancient microbes. NASA/JPL-Caltech/MSSS The spots could've been formed by non-biological processes, and that's something scientists will have to figure out. "We cannot say right now that we have discovered life on Mars, Katie Stack Morgan, the deputy project scientist, said. "But what we are saying is that we have a potential biosignature, which is a set of features that could have a biological origin but do need further study and more data." NASA still has to bring back the samples Perseverance had collected to our planet, including Cheyava Falls. As The New York Times notes, the Mars Sample Return mission is years behind schedule and would not be able to bring back rocks from the red planet until 2040 instead of in the early 2030's like originally planned. NASA recently asked aerospace companies for alternative solutions on how to get the samples to Earth much sooner and will finance their studies due later this year. Scientists will also have to conduct extensive testing to rule out contamination and non-biological processes, as well as other possible explanations for how the leopard spots had formed, before they can proclaim that they're indeed evidence of ancient Martian life.
