So you’re considering a projector? Perhaps you’re a movie fan who wants to curate their own home cinema night, popcorn and all. Or you’re a gamer who wants to step out onto a distant planet and blast life-sized aliens to smithereens? With the right projector you can do all of these things, and so much more. If you are indeed ready to take the plunge, or are looking to upgrade, there are a few considerations to take into account. Projectors require a little more planning and setting up when compared with televisions. To get the best out of one, you’ll need to attach it to the ceiling, as – unlike TVs – you’ll need distance between the lens and the screen to project. (Unless of course, you go for a short throw model, but we’ll talk a little more on this later.) A ceiling-mounted beamer also eliminates the possibility of shadows cast by passing people or pets.

Google has worked for years to position itself as a responsible steward of AI. Its research lab hires respected academics, publishes groundbreaking papers, and steers the agenda at the field’s biggest conferences. But now its reputation has been badly, perhaps irreversibly damaged, just as the company is struggling to put a politically palatable face on its empire of data. The company’s decision to fire Timnit Gebru and Margaret Mitchell — two of its top AI ethics researchers, who happened to be examining the downsides of technology integral to Google’s search products — has triggered waves of protest. Academics have registered their discontent in various ways. Two backed out of a Google research workshop, a third turned down a $60,000 grant from the company, and a fourth pledged not to accept its funding in the future. Two engineers quit the company in protest of Gebru’s treatment and just last week, one of Google’s top AI employees, a research manager named Samy Bengio who … [Read more...] about Google is poisoning its reputation with AI researchers
On Tuesday morning, the US Food and Drug Administration and the Centers for Disease Control and Prevention issued a release acknowledging an extremely rare clotting disorder was associated with the use of the Johnson & Johnson COVID vaccine. The problem is actually less than a one-in-a-million issue; in data from the US, where 6.8 million doses of this vaccine have been used, there have only been six instances of the clotting problem detected. Because the clots call for an unusual treatment, however, the organizations are calling for a pause in administering the shot. This will provide them with time to ensure the medical community is aware of the appropriate treatment. This is not the first vaccine to create extremely rare clotting issues. They've also been seen following use of the AstraZeneca vaccine . The problem appears to be caused by the harmless virus (an Adenovirus) that carries a single gene from SARS-CoV-2 in order to elicit an immune response. The leading … [Read more...] about J&J COVID vaccine use paused due to one-in-a-million complication

The next few years will see billions of users regularly using facial recognition technology to secure payments made through their smartphone, tablets or smartwatches, according to new analysis carried out by Juniper Research. Smartphone owners are already used to staring at their screens to safely unlock their devices without having to dial in a secret code; now, facial recognition will increasingly be deployed to verify the identity of a user making a payment with their handset, whether that's via an app or directly in-store, in wallet mode.
