Apple's new Magnifier for Mac is an accessibility feature everyone can use
Apple just announced new accessibility features coming to its operating systems. There's a redesigned braille input experience, and a new reader that allows you to customize your text so it's more legible. But there's one that will be great for anyone attending any lecture or presentation: Magnifier for Mac.
The iPhone and iPad got their Magnifier apps back in 2016. It worked pretty much like the iOS camera: You point your device anywhere you want and zoom in to the desired level. It also allows you to apply real-time filters to enhance readability depending on your vision's condition, like turning a book's black text over white page into white text over blue, as well as changing the image's contrast and brightness. It also can detect objects around you.
The new Mac version takes all that up to an 11 with its new features. To get the view of the world the new Magnifier needs, you will need to use a USB camera or an iPhone. The latter automatically connects to your computer using MacOS's Continuity Camera feature, allowing you to use your phone as the eyes for your Apple desktop or laptop. Zoom in to focus on something far away, apply the same filters, and adjust the image, just like in iOS and iPadOS.
A matter of perspective
What makes the update brilliant is the new perspective adjustment. Since you can't move your Mac around like with Apple's handheld devices, you need a way to frame the text you want to read correctly.
Like Apple's introductory video shows, you can point your Mac with the attached camera to a whiteboard. Since you are probably not going to be looking at it from a fully perpendicular perspective, the app allows you to draw a polygon by clicking on each corner of the whiteboard in your screen. Then, applying some image deformation magical maths, Magnifier will automatically correct the perspective, turning the skewed whiteboard with deformed text into a perfect flat image that gives you the best view in the class, auditorium, or conference room.
From there, you can do whatever you want with that text, including transforming handwriting into a typeface for easier reading. Magnifier uses Apple's new Accessibility Reader, too, which allows you to customize how a page looks with the colors, fonts, and sizes you prefer—as well as copying and pasting from the whatever text the camera is looking at, regardless of it being handwritten or not. It's similar to what you can do now with other Apple apps, like Preview, but in one continuous, seamless experience.
Bonus points: Magnifier also supports reading any paper-based media using Desk View, the feature that uses your iPhone's wide-angle lens to capture what's flat on the table in front of your screen. Just put that novel on the table and transform its small type into something you can read easily (or have your Mac's text-to-speech abilities to read it for you).
It's easy to imagine every single student, office person, and TED Talk drone using the new Magnifier to get a better experience possible at a presentation—sleeping pills notwithstanding—once it comes out 'later this year' (according to Apple). This new little jewel will make your Macbook the best seat in the house no matter where you are sitting.

Major U.S. banks poised for massive shift in approach toward cryptocurrency: 'Defend your right to buy'
Despite the instability of cryptocurrency, major U.S. banks are considering a move toward supporting these emerging currencies, Reuters reported. However, they are being rightfully cautious given the shifting legal landscape and how easy it would be to run afoul of laws designed to keep our financial systems honest. Reuters spoke to industry executives about the possibility and revealed that internal discussions are already happening regarding the potential change. However, no bank wants to make the first move. "When I look at the bitcoin universe, the leverage in the system, the misuse in the system, the money laundering issues, trafficking, I'm not a fan of it," said Jamie Dimon, CEO of the largest U.S. bank, JPMorgan Chase, per Reuters. "We're going to allow you to buy it, we're not going to custody it. ... I don't think you should smoke, but I defend your right to smoke. I defend your right to buy bitcoin." It's not surprising that banks have their eye on this move. President Trump has courted cryptocurrency enthusiasts with promises to create a federal cryptocurrency reserve and make other investments as president. However, it's also not surprising that they're hanging back. The risk is high, and anti-money laundering rules and other regulations could sharply limit their activities, with no guarantees yet as to how those rules may change. When banks do enter the game, it will likely be in small ways, as partners to existing organizations. They may also want to create a stablecoin of their own. It's in the best interests of the American public for legal protections regarding cryptocurrency to be strengthened and for banks to be cautious. All the computing power needed is bad for the environment, at least until we switch to a more eco-friendly cryptocurrency. In the meantime, until banking regulators speak up, we're unlikely to see much change in crypto banking. Do you think the federal government should give us tax breaks to improve our homes?

Snowcap Compute raises $23 million for superconducting AI chips
By Stephen Nellis SAN FRANCISCO (Reuters) -Snowcap Compute, a startup working on building artificial intelligence computing chips using superconducting technology, on Monday raised $23 million and said that the former CEO of Intel will join its board. Snowcap aims to build computers that could one day beat today's best artificial intelligence systems, while using a fraction of the electricity. To do that, Snowcap plans to use a new kind of chip made with superconductors, which are materials that allow current to flow without electrical resistance. Scientists understand superconductors well and have theorized about making computer chips with them since at least the 1990s, but have faced a major challenge: To work, the chips need to be kept very cold in cryogenic coolers which themselves consume a lot of electricity. For decades that made superconductor chips a nonstarter, until AI chatbots ignited huge demand for computing power at the same time that conventional chips are hitting the limits of how much performance they can wring from every watt of power and are taxing electricity grids. Nvidia's forthcoming "Rubin Ultra" AI data center server due in 2027, for example, is expected to consume about 600 kilowatts of power. That means operating that single server at full capacity for one hour would consume about two thirds the average power that a U.S. house uses in a month. In that kind of changed world, dedicating a portion of a data center's power needs to cryogenic coolers makes sense if the performance gains are good enough, said Michael Lafferty, Snowcap's CEO, who formerly oversaw work on futuristic chips at Cadence Design Systems. Snowcap believes that even after accounting for energy used in cooling, its chips will be about 25 times better than today's best chips in terms of performance per watt. "Power (efficiency) is nice, but performance sells," Lafferty said. "So we're pushing the performance level way up and pulling the power down at the same time." Snowcap's founding team includes two scientists - Anna Herr and Quentin Herr - who have done extensive work on superconducting chips at chip industry research firm Imed and defense firm Northrop Grumman, as well as former chip executives from Nvidia and Alphabet's Google. While the chips can be made in a standard factory, they will require an exotic metal called niobium titanium nitride that Lafferty said depends on Brazil and Canada for key ingredients. Snowcap plans its first basic chip by the end of 2026, but full systems will not come until later. Despite the long development timeline, Pat Gelsinger, Intel's former CEO who led the investment for venture firm Playground Global and is joining Snowcap's board, said the computing industry needs a sharp break from its current trajectory of consuming ever more electricity. "A lot of data centers today are just being limited by power availability," Gelsinger said. Also joining the funding round were Cambium Capital and Vsquared Ventures.
