Developer (and former HackADay editor) Brian Benchoff has designed what he’s calling a “minimum viable computer.” It’s a Linux-ready computer that’s small enough to slide into your pocket, and which could be made from about $15 worth of parts… theoretically.

In practice, that price doesn’t reflect assembly and shipping costs and you’d need to order enough parts for around 10,000 units in order to bring the costs that low. But Benchoff says he does eventually “plan to make this thing available.”

That could mean that a crowdfunding campaign is on the way, or some other effort to actually make it possible to make the economies of scale work so that this little computer could actually be sold for less than the price of a crappy pre-paid phone.

For now, you can find more details about the design and parts list at Benchoff’s GitHub page. Specs for the latest design include:

  • 2.3 inch, 320 x 240 pixel non-touch display
  • 533 MHz Allwinner F1C100s ARM9 processor
  • 32MB DDR memory
  • microSD card reader & 64GB card for storage
  • 48-key keyboard with TV remote-like silicone membrane
  • USB 2.0 Type-A port (data)
  • USB Type-C port (for 500 mA charging only)
  • 2 x AAA NiMH rechargable batteries

There’s also a custom printed circuit board, enclosure, and some other odds and ends which bring the total cost for materials to $14.16 at current prices when you order 1,000 units of each part. Benchoff notes that even with supply chain shortages, every component in the bill of materials is currently available.

With pretty barebones specs, no touch or mouse input, and no wireless capabilities, the little computer isn’t exactly designed as a modern smartphone or laptop replacement. Benchoff doesn’t even plan to code a graphical user interface for the little computer. But it can run DOOM, like most things. And you could program it to perform a variety of functions – it could be used as a multi-factor authentication device or a crypto wallet, for example.

It’s also possible some specs could change before the computer is produced – a larger display and bigger keyboard would go a long way toward improving usability, for example. But since the schematics, design files, and software will all be open source, folks who want to customize their own may also have the opportunity.

Today’s best deals: Apple AirPods Pro, MacBook Air, and more

It's time for another Dealmaster. Our latest roundup of the best deals from around the web includes a decent price drop on Apple's AirPods Pro, which are currently down to $180 at Amazon and Walmart. That's about $70 off Apple's MSRP and about $15 off the average Amazon price we've seen for the true wireless noise-canceling earphones over the past few months. For reference, we did see them drop as low as $159 around Black Friday, but this deal matches the best price we've tracked for about two months.

We've recommended the AirPods Pro a number of times since they launched in late 2019. Though they're getting up there in age, they continue to provide stronger active noise cancellation than most competing wireless earbuds, an effective ambient sound mode that layers outside noise under your music, and a balanced, neutral sound that still ranks among the best in the category. The ear pieces are light and comfortable and have an IPX4 rating for everyday sweat resistance. Apple now packages the AirPods Pro with a MagSafe Charging Case, an addition it made when it announced the third-gen AirPods last fall. And like all AirPods, the Pro pair brings a number of useful bonus features ("Find My" tracking, "Hey Siri" voice controls, quick device swapping) when used with other Apple devices.

The Pros are far less useful to Android users, to be clear. And at roughly five hours of continuous playback, their battery life is lacking. If you want a similar pair of noise-canceling Apple earphones that are better for working out, the Beats Fit Pro earned a spot on our holiday gift guide last month for packing many of the same benefits in a sportier design. Reports suggest that Apple plans to refresh the AirPods Pro with a new design later this year, too, though those may launch closer to the end of 2022. All that said, if you're an iPhone user who wants a premium pair of noise-canceling earphones today, this deal is a good value.

Chromebooks may borrow the Pixel’s battery-preservation trick

Feature would extend battery life span with AI.

You can never have enough battery life, but keeping your device's battery at a constant 100 percent can degrade its life span. Many laptops already use artificial intelligence to control how a device uses its battery, and Chromebooks are now apparently heading down that road as well.

As spotted by 9to5Google this week, a new code change in the Chromium Gerrit references "adaptive charging" coming to Chromebooks. The change's description says the feature uses machine learning to "minimize the amount of time the device spends at full battery to preserve battery lifetime."

This system would be similar to features we've seen on higher-end Windows laptops. For example, HP's upcoming Elite Dragonfly 3 laptop will use intelligent charging, which, as the vendor puts it, "learns work patterns to optimize power consumption." It's unclear how exactly the developing Chrome OS feature would work, though. It appears that Google will allow the feature to be toggled off, and a notification will let you know when it's on.

Magisk is a popular utility for rooting and customizing Android phones through installation of modules. The latest version brings support for Android 12 and a new feature called Zygisk that could bring support for new, more powerful modules that can run code in every Android apps’ processes.

But Magisk v24 also marks the end of a few features: developer John Wu has ended support for a centralized Magisk Modules repository and he’s no longer developing MagiskHide.

Now that there’s no longer a centralized repository, developers can specify an update URL that Magisk will use to check for updates. That way you’ll be able to continue receiving updates delivered directly by the developer.

MagiskHide, meanwhile, was a feature that allowed users to trick some Android apps into thinking a device wasn’t rooted and/or its bootloader wasn’t unlocked. Some apps, including banking and mobile payment apps use Google’s SafetyNet feature to block you from using them on devices that have been tampered with for security reasons, and MagiskHide allowed you to continue using those apps on rooted devices, since you were presumably the person who decided to tamper with your device and are hopefully aware of the risks.

Other apps including some games and video streaming services rely on SafetyNet in order to prevent piracy or cheating.

Wu has said he was getting tired of the cat-and-mouse game involved in keeping MagiskHide working, because it involved poking holes in Google’s security… which Google usually patched, requiring a new build. Now Wu himself is working on Google’s Android Platform Security team, and revealed months ago that he would be ending his work on MagiskHide.

But that doesn’t mean you can’t circumvent SafetyNet on a rooted Android phone anymore. A number of third-party solutions have popped up in recent months, including:

  • Universal SafetyNet Fix – Developer kdrag0n’s Magisk module (use the Zygisk version with Magisk v24/Android 12)
  • Shamiko – Work in progress Magisk module, available for download from a Telegram group
  • ih8sn – Experimental method that doesn’t involve Magisk, but which allows you to spoof prop values to pass SafetyNet checks, developed by members of the LineageOS team, but not an official LineageOS project

Other changes in Magisk v24 include support for devices that are unable to run 32-bit code, and which are 64-bit only and a number of bug fixes and improved support for some devices from Sony, Meizu, Oppo, OnePlus, and Realme.

Meta’s cryptocurrency ploy all but dead with Libra/Diem seeking to sell assets

Stablecoin raised concerns of “excessive concentration of economic power.”

After years of effort, Meta’s cryptocurrency initiative has collapsed under the weight of regulatory scrutiny.

The Diem Association, formerly known as the Libra Association, is considering selling its assets and returning money to investors, according to a Bloomberg report. There’s not much to sell, though. The company doesn’t have much in the way of physical assets—just some intellectual property. Perhaps the most valuable part of the association is its engineers. Diem is reportedly looking for a “new home” for them.

Mark Zuckerberg first announced the project in 2019, back when his company was named Facebook and the project was named Libra. He said the cryptocurrency would serve as the foundation for payments within Facebook Messenger and WhatsApp. Zuckerberg managed to convince dozens of companies to become founding members of the backing organization, including Visa, MasterCard, Uber, Lyft, eBay, Spotify, and Andreessen Horowitz.

Maserati wants its new MC20 supercar to rekindle that old magic

It re-enters the fray with cutting-edge technology and head-turning design.

Although the name Maserati is synonymous with exotic performance, the automaker hasn't unleashed a mid-engined supercar on the world in nearly two decades. In the years since the debut of the limited-production MC12 back in 2004, the company shifted its focus toward sedans and sport-utility vehicles like the Levante to reach a wider audience. Lackadaisical development and a liberal pilfering of the Stellantis parts bin, however, had threatened to dilute the brand.

That all changes with the introduction of the MC20. Developed in Modena, Italy, and built from the ground up on an all-new carbon-fiber monocoque chassis designed to accommodate coupe, convertible, and electric configurations, the MC20 shares very little with the rest of the vehicles in the current Maserati lineup. And thanks in part to its "Nettuno" V6, Maserati's new 3,300-pound halo car boasts the best power-to-weight ratio in a segment that includes names like Porsche, Lamborghini, and McLaren.

As with the platform, Maserati engineers took a clean-sheet approach when designing MC20’s power plant to create a dry sump engine that's wholly unique to the brand. The mill uses on-demand twin-combustion technology derived from Formula 1 that places a combustion chamber between the central spark plug and the conventional combustion chamber to improve both performance and efficiency, and the resulting peak output is 621 hp (463 kW) and 538 lb-ft (729 Nm) of torque. Those figures make the engine one of the most power-dense in production today, and that grunt is sent exclusively to the rear wheels through the same Tremec eight-speed dual-clutch transmission used in the C8 Corvette, though it has been dialed in for the requirements of the Maserati V6.
