unixbhaskar shares a report from Phoronix: The X86_NATIVE_CPU Kconfig build time option has been merged for the Linux 6.16 merge window as an easy means of enforcing "-march=native" compiler behavior on AMD and Intel processors to optimize your kernel build for the local CPU architecture/family of your system. For those wanting to "-march=native" your Linux kernel build on AMD/Intel x86_64 processors, the new CONFIG_X86_NATIVE_CPU option can be easily enabled for setting that compiler option on your local kernel builds.

The CONFIG_X86_NATIVE_CPU option is honored if compiling the Linux x86_64 kernel with GCC or LLVM Clang when using Clang 19 or newer due to a compiler bug with the Linux kernel on older compiler versions. In addition to setting the "-march=native" compiler option for the Linux kernel C code, enabling this new Kconfig build option also sets "-Ctarget-cpu=native" for the kernel's Rust code too. "It seems interesting though," comments unixbhaskar. "If the detailed benchmark shows some improvement with the option selected, then distros might start to adopt it for their flavor."

"There's no shortage of videos showing Steam running on expensive ARM single-board computers with discrete GPUs," writes Slashdot reader VennStone. "So I thought it would be worthwhile to make a guide for doing it on (relatively) inexpensive RK3588-powered single-board computers, using Box86/64 and Armbian." The guides I came across were out of date, had a bunch of extra steps thrown in, or were outright incorrect... Up first, we need to add the Box86 and Box64 ARM repositories [along with dependencies, ARMHF architecture, and the Mesa graphics driver]...
The guide closes with a multi-line script and advice to "Just close your eyes and run this. It's not pretty, but it will download the Steam Debian package, extract the needed bits, and set up a launch script." (And then the final step is sudo reboot now.)

"At this point, all you have to do is open a terminal, type 'steam', and tap Enter. You'll have about five minutes to wait... Check out the video to see how some of the tested games perform." At 720p, performance is all over the place, but the games I tested typically managed to stay above 30 FPS. This is better than I was expecting from a four-year-old SOC emulating x86 titles under ARM.

Is this a practical way to play your Steam games? Nope, not even a little bit. For now, this is merely an exercise in ludicrous neatness. Things might get a wee bit better, considering Collabora is working on upstream support for RK3588 and Valve is up to something ARM-related, but ya know, "Valve Time"...
"You might be tempted to enable Steam Play for your Windows games, but don't waste your time. I mean, you can try, but it ain't gonna work."

"For developers and organisations that require a custom software image, a flexible and transparent build system is essential," according to an announcement Friday at Raspberry Pi.com.

"[T]o support these customers, we have created rpi-image-gen, a powerful new tool designed to put you in complete control of your Raspberry Pi images." If you're building an embedded system or an industrial controller, you'll need complete control over the software resident on the device, and home users may wish to build their own OS and have it pre-configured exactly the way they want... rpi-image-gen is an alternative to pi-gen, which is the tool we use to create and deploy the Raspberry Pi OS distribution. rpi-image-gen... offers a very granular level of control over file system construction and software image creation... [B]eing able to help reduce software build time, provide guaranteed ownership of support, and reuse standard methodologies to ensure authenticity of software were all of paramount importance, and among the reasons why we created a new home-grown build tool for Raspberry Pi devices...

There is a small number of examples in the tree which demonstrate different use cases of rpi-image-gen [including the lightweight image slim and webkiosk for booting into browser kiosk mode]. All create bootable disk images and serve to illustrate how one might use rpi-image-gen to create a bespoke image for a particular purpose. The number of examples will grow over time and we welcome suggestions for new ones... Visit the rpi-image-gen GitHub repository to get started. There, you'll find documentation and examples to guide you through creating custom Raspberry Pi images.
Some technical details from the announcement.

• "Similar to pi-gen, rpi-image-gen leverages the power, reliability, and trust of installing a Debian Linux system for the device. However, unlike pi-gen, rpi-image-gen introduces some new concepts [profiles, image layouts, and config] which serve to dictate the build footprint and installation."

• The tool also lets you exclude from your package "things that would otherwise be installed as part of the profile."

• The tool's GitHub repository notes that it also allows you output your software bill of materials (SBOM) "to list the exact set of packages that were used to create the image." And it can even generate a list of CVEs identified from the SBOM to "give consumers of your image confidence that your image does not contain any known vulnerabilities."

Adafruit Industries used large language model (LLM) tool Claude Code to streamline hardware development, writes managing director ptorrone.

In a demo video Limor 'Ladyada' Fried compares the LLM's command-line interface to working with the build-automation tool CMake or "a weird cross between IRC and a BBS." The first step was converting a PDF of the hardware's datasheet into text, and Claude Code first displays the appropriate Bash command, while asking "Do you want to proceed?" ("What's nice is that it doesn't make changes, even though it has write access to files in the directory...") Eventually from the data sheet it creates things like an accurate register map, C++ headers, and even license text — and more.

"We are using it to automate parts of the coding and debugging process for an Arduino-compatible Metro Mini board with an OPT 4048 color sensor," writes ptorrone: Using Claude Code's shell access, we can compile, upload, and test code in a semi-automated workflow, allowing the LLM to suggest fixes for errors along the way... While the AI isn't perfect for high-level driver development, it's proving VERY useful for tedious debugging and super-fast iterative improvements, bringing hardware automation closer to ...reality.
In the video Fried describes it like this. "I have a full debugging cycle, where I'm there — I'm like driving the car — but I have this copilot that's telling me where to go..."

"I feel like I'm getting closer to having a semi-automated way of doing driver development."

"Single-board computer maker Raspberry Pi is updating its cute little computer-meet-keyboard device with better specifications..." reports TechCrunch.

They call the new $90 Raspberry Pi 500 "not as intimidating" because "when you look at the Raspberry Pi 500, you can't see any chipsets or printed circuit board... The idea with the Raspberry Pi 500 is that you can plug in a mouse and display, and you're ready to hit the ground running." When it comes to specifications, the Raspberry Pi 500 features a 64-bit quad-core Arm processor (the same one as the Raspberry Pi 5 uses); 8GB of RAM; 2 micro-HDMI ports, with support for up to two 4K displays; 3 traditional USB ports (but no USB-C besides the power port unfortunately); a Gigabit Ethernet port; and a 40-pin expansion header. It comes with native Wi-Fi and Bluetooth support.

More importantly, this device brings us back Raspberry Pi's roots. Raspberry Pi computers were originally intended for educational use cases... The Raspberry Pi 500 draws inspiration from the not-for-profit Raspberry Pi Foundation's roots. It's the perfect first computer for school. In many ways, it's much better than a Chromebook or an iPad because it is both cheap and highly customizable — encouraging creative thinking. The Raspberry Pi 500 comes with a 32GB SD card preloaded with Raspberry Pi OS, a Debian-based Linux distribution...

In other news, Raspberry Pi has announced another brand-new product: the Raspberry Pi Monitor. It's a 15.6-inch 1080p monitor with a price-tag of $100.
Tom's Hardware calls the Pi 500 "a superb update" to the original computer-in-a-keyboard Raspberry Pi 400: Having the ports at the back makes total sense. It tidies up the cables, and means that we only need one thick edge, the rest can be as thin as possible... [P]assive cooling performance is remarkable, even when overclocked to 3 GHz...! I did have to adjust the voltage to keep everything stable, but once I found the magic numbers, the system was stable and performed remarkably well... [I]t ran buttery smooth and surprisingly, cool under stress. I'd consider this a successful overclock and one that I would happily keep as a permanent addition...

Just like the Raspberry Pi 400, the Pi 500 is there to be a 21st century equivalent to the home computers of the 1980s. You plug in to a wedge-shaped keyboard, hook up to your display, and start work. But the Raspberry Pi 500 has much more processing power than the Pi 400, and that means it can be a viable desktop computer for those that don't need an RTX 4090 or a power-hungry CPU.

I like the Raspberry Pi 500. It's a powerful machine, in a pleasant package. I'm old enough to remember the 1980s home computer craze, and this, just like the Pi 400, reminds me of that time. But now we have much more power... The Raspberry Pi 500 is the kit that you buy as a gift for someone, or as a child's first computer. I can see this being used in schools and to an extent in offices around the world.

"We're excited to be working with Microsoft to keep Xboxes running longer and out of the waste heap," iFixit's director of sustainability told The Verge. iFixit now sells genuine Xbox parts you can use to repair your Xbox Series X or S and offers official guides to help with fixes [including both the all-digital and disk drive editions]...

iFixit's Microsoft Repair Hub also features iFixit's parts for repairing Microsoft Surface devices, which it started selling in 2023. "Since we launched our Surface parts collaboration with Microsoft last year, we've been helping our customers repair their own Microsoft laptops and tablets — and it's awesome to be able to offer Xbox owners the same opportunity," says Elizabeth Chamberlain, iFixit's director of sustainability.
The article points out that iFixit also sells "nearly every part of the Steam Deck" and "a bunch of repair guides for Valve's handheld PC, too," along with genuine repair parts for Google's Pixel phones and the Pixel Tablet.

"With Microsoft, we've created a one-stop place for guides, tools, and spare parts to make self-service repair accessible to anyone," says iFixit's new web page. "Imagine how different the world would be if repairing every device could be this easy."

Microsoft has released Windows 11 Dev build 26120.1930, which contains the ability to remap the Copilot key. The changes are rolling out gradually to Dev Insiders with the "Get the latest features as soon as they are available" toggle on. Neowin reports: [H]ere are the updates that are also gradually rolling out, but this time for all Dev Insiders: "We are adding the ability to configure the Copilot key. You can choose to have the Copilot key launch an app that is MSIX packaged and signed, thus indicating the app meets security and privacy requirements to keep customers safe. The key will continue to launch Copilot on devices that have the Copilot app installed until a customer selects a different experience. This setting can be found via Settings - Personalization - Text input. If the keyboard connected to your PC does not have a Copilot key, adjusting this setting will not do anything. We are planning further refinements to this experience in a future flight." Other changes introduced in the build include a new simplified Chinese font, Windows Sandbox improvements, and several bug fixes. Full release notes are available here.

How were the Pyramids built? NBC News reported on "a possible answer" after new evidence was published earlier this year in the journal Communications Earth & Environment.

The theory? "[A]n extinct branch of the Nile River once weaved through the landscape in a much wetter climate." Dozens of Egyptian pyramids across a 40-mile-long range rimmed the waterway, the study says, including the best-known complex in Giza. The waterway allowed workers to transport stone and other materials to build the monuments, according to the study. Raised causeways stretched out horizontally, connecting the pyramids to river ports along the Nile's bank.

Drought, in combination with seismic activity that tilted the landscape, most likely caused the river to dry up over time and ultimately fill with silt, removing most traces of it.

The research team based its conclusions on data from satellites that send radar waves to penetrate the Earth's surface and detect hidden features. It also relied on sediment cores and maps from 1911 to uncover and trace the imprint of the ancient waterway. Such tools are helping environmental scientists map the ancient Nile, which is now covered by desert sand and agricultural fields... The study builds on research from 2022, which used ancient evidence of pollen grains from marsh species to suggest that a waterway once cut through the present-day desert.
Granite blocks weighing several tons were transported hundreds of miles, according to a professor of Egyptology at Harvard University — who tells NBC they were moved without wheels. But this new evidence that the Nile was closer to the pyramids lends further support to the evolving "canals" theory.

In 2011 archaeologist Pierre Tallet found 30 different man-made caves in remote Egyptian hills, according to Smithsonian magazine. eventually locating the oldest papyrus rolls ever discovered — which were written by the builders of the Great Pyramid of Giza, describing a team of 200 workers moving limestone upriver. And in a 2017 documentary archaeologists were already reporting evidence of a waterway underneath the great Giza plateau.

Slashdot reader Smonster found an alternate theory in this 2001 announcement from Caltech: Mory Gharib and his team raised a 6,900-pound, 15-foot obelisk into vertical position in the desert near Palmdale by using nothing more than a kite, a pulley system, and a support frame... One might ask whether there was and is sufficient wind in Egypt for a kite or a drag chute to fly. The answer is that steady winds of up to 30 miles-per-hour are not unusual in the areas where the pyramids and obelisks are found.
"We're not Egyptologists," Gharib added. "We're mainly interested in determining whether there is a possibility that the Egyptians were aware of wind power, and whether they used it to make their lives better."

"The cab was cut from a 1997 Jeep Grand Cherokee," writes the New York Times. "The engine once revved up a 1985 Toyota Celica; and 107 hand-sewn rubber segments, courtesy of Mr. Tymofichuk's wife, help to direct low-pressure air beneath the craft so that it rises eight inches above the ground..." On a cold spring day in a small garage in Alberta, Canada, an engine revved up and an improbable machine — fabricated from auto parts, a hand-sewn rubber skirt and an abandoned fiberglass hull — came to life.

A homemade hovercraft began to rise off the ground with a small crew standing by.

The successful liftoff was the culmination of a lifelong fascination of Robert Tymofichuk, 55, who spent about 1,800 hours over a year working on it [according to this nifty video on YouTube ]. And, to the gratitude of passengers, it comes with heated seats. "If you're going through all that hassle, you might as well make yourself comfortable," Mr. Tymofichuk said. He repurposed the seats from a Volkswagen, so the heating coils were already installed.
Achieve speeds around 40 miles per hour (or 64 kmph), "Mr. Tymofichuk's hovercraft now sails above land and water, a bright red gem coasting over the Saskatchewan River," according to the article. And it also quotes Mr. Tymofichuk as saying it's the fulfillment of a childhood dream.

"To actually have something constructed with your own hands be zipping around, and it's fully functional — it's like magic."

Digital rights activists want device manufacturers to disclose a "guaranteed minimum support time" for devices — and federal regulations ensuring a product's core functionality will work even after its software updates stop.

Influential groups including Consumer Reports, EFF, the Software Freedom Conservancy, iFixit, and U.S. Pirg have now signed a letter to the head of America's Consumer Protection bureau (at the Federal Trade Commision), reports The Register: In an eight-page letter to the Commission (FTC), the activists mentioned the Google/Levis collaboration on a denim jacket that contained sensors enabling it to control an Android device through a special app. When the app was discontinued in 2023, the jacket lost that functionality. The letter also mentions the "Car Thing," an automotive infotainment device created by Spotify, which bricked the device fewer than two years after launch and didn't offer a refund...

Environmental groups and computer repair shops also signed the letter... "Consumers need a clear standard for what to expect when purchasing a connected device," stated Justin Brookman, director of technology policy at Consumer Reports and a former policy director of the FTC's Office of Technology, Research, and Investigation. "Too often, consumers are left with devices that stop functioning because companies decide to end support without little to no warning. This leaves people stranded with devices they once relied on, unable to access features or updates...."

Brookman told The Register that he believes this is the first such policy request to the FTC that asks the agency to help consumers with this dilemma. "I'm not aware of a previous effort from public interest groups to get the FTC to take action on this issue — it's still a relatively new issue with no clear established norms," he wrote in an email. "But it has certainly become an issue" that comes up more and more with device makers as they change their rules about product updates and usage.
"Both switching features to a subscription and 'bricking' a connected device purchased by a consumer in many cases are unfair and deceptive practices," the groups write, arguing that the practices "infringe on a consumer's right to own the products they buy." They're requesting clear "guidance" for manufacturers from the U.S. government. The FTC has a number of tools at its disposal to help establish standards for IoT device support. While a formal rulemaking is one possibility, the FTC also has the ability to issue more informal guidance, such as its Endorsement Guides12 and Dot Com Disclosures.13 We believe the agency should set norms...
The groups are also urging the FTC to:

• Encourage tools and methods that enable reuse if software support ends.

• Conduct an educational program to encourage manufacturers to build longevity into the design of their products.

• Protect "adversarial interoperability"... when a competitor or third-party creates a reuse or modification tool [that] adds to or converts the old device.

Sean Hollister reports via The Verge: At Build, Microsoft now says it's adding native version control to File Explorer by integrating systems like Git, letting you see new changes and comments directly from the app. Here's a cropped and zoomed version of the provided screenshot so you can get a better look. [...] Microsoft says it's also letting File Explorer natively compress files to 7-zip and TAR; currently, the right-click context menu has a "Compress to ZIP file" option, but ZIP is thought to be a bit antiquated in terms of how much compression you get.

Michael Larabel reports via Phoronix: While Fedora 41 in late 2024 is aiming to have more reproducible package builds, openSUSE Factory has already achieved a significant milestone in bit-by-bit reproducible builds. Since last month openSUSE Factory has been producing bit-by-bit reproducible builds sans the likes of embedded signatures. OpenSUSE Tumbleweed packages for that rolling-release distribution are being verified for bit-by-bit reproducible builds. SUSE/openSUSE is still verifying all packages are yielding reproducible builds but so far it's looking like 95% or more of packages are working out. You can learn more via the openSUSE blog.

Richard Speed reports via The Register: Copilot in Windows is set to get even more assertive after Microsoft added a function that makes the AI assistant's window pop up after a user's cursor hovers over the icon in the task bar. [...] Windows Insiders on the Beta Channel â" with the option to get the latest updates turned on â" will soon find themselves on the receiving end of what Microsoft calls "a new hover experience for Copilot in Windows" from build 22635.3276.

If your mouse cursor happens to drift over to the Copilot icon on the taskbar, the Copilot pane will open to make users aware of the delights on offer. The result, we suspect, will be to educate users in the art of switching off the function. Much like Widgets, which will also make its unwanted presence felt should a user move a mouse over its icon. A swift hop into taskbar settings is all it takes to make the icons disappear, for now at least. The new feature is being piloted but considering the proximity of the Beta Channel to Release Preview, there is every chance the pop-up will, er, pop up in a release version of Windows before long.

The company behind Flipper Zero expects $80 million in sales this year, which ZDNet estimates at around 500,000 unit sales.

In its Kickstarter days the company sold almost $5 million as preorders, remembers TechCrunch, and the company claims it sold $25 million worth of the devices last year: So what are they selling? Flipper Zero is a "portable gamified multi-tool" aimed at everyone with an interest in cybersecurity, whether as a penetration tester, curious nerd or student — or with more nefarious purposes. The tool includes a bunch of ways to manipulate the world around you, including wireless devices (think garage openers), RFID card systems, remote keyless systems, key fobs, entry to barriers, etc. Basically, you can program it to emulate a bunch of different lock systems.

The system really works, too — I'm not much of a hacker, but I've been able to open garages, activate elevators and open other locking systems that should be way beyond my hacking skill level. On the one hand, it's an interesting toy to experiment with, which highlights how insecure much of the world around us actually is. On the other hand, I'm curious if it's a great idea to have 300,000+ hacking devices out in the wild that make it easy to capture car key signals and gate openers and then use them to open said apertures.
The company points out that their firmware is open source, and can be inspected by anyone.

ZDNet calls it "incredibly user-friendly" and "a fantastic educational tool and a stepping stone to get people — young and old — into cybersecurity," with "a very active community of users that are constantly finding new things to do with it". (Even third-party operating systems are available).

"Instead of looking like some scary hacking tool, all black and bristling with antennas, it looks like a kid's toy, all plastic and brightly colored," writes ZDNet. "It reminds me of Tamagotchis..."

The latest Windows 11 Insider Preview build includes improved support for passkeys, a new standard for passwordless authentication, as well as support for Unicode 15 emoji, changes to Windows' location-based time zone setting, and a handful of bug fixes. Microsoft has also rolled back proposed changes to the File Explorer that would have removed several relatively obscure settings from the Folder Options window. Ars Technica reports: Though the Microsoft Edge browser has supported passkeys for a while now, this week's Insider build expands support to "any app or website that supports passkeys," which can use built-in Windows Hello authentication (either via a PIN, fingerprint reader, or face-scanning camera) to sign you in without requiring a password. You can also view the full list of passkeys that have been created on your device and delete individual passkeys if you no longer want to use them. If your browser natively supports passkeys and has its own user interface for handling them, you'll need to select "Windows Hello or external security key" to use the built-in Windows UI instead.

The new Insider build also adds support for Unicode 15 emoji, a few changes to Windows' location-based time zone setting, and a handful of fixes. But most notably for people who complained about last week's Insider build, Microsoft has rolled back proposed changes that would have removed several relatively obscure settings from the Folder Options window in the File Explorer. "As is normal for the Dev Channel, we will often try things out and get feedback and adjust based on the feedback we receive," wrote Microsoft's Amanda Langowski and Brandon LeBlanc in a post detailing the new build's changes.

At its Build 2023 conference this week, Microsoft announced Windows 11 will soon be able to run Win32 apps in isolation mode. XDA Developers reports: Starting [today], Microsoft is launching a preview of Win32 apps in isolation for Windows 11 customers. As the name suggests, it will allow users to run Win32 apps in an isolated environment so that they can be sandboxed from the rest of the operating system in order to further strengthen security. The idea is to leverage Windows 11's isolation capabilities to run Win32 apps in an environment where they don't have access to critical Windows components and subsystems. This will ensure that if someone runs a compromised Win32 app in isolation, it will be very difficult for an attacker to break through the sandbox and penetrate the rest of the system. This capability will be available in public preview for both enterprise customers and consumers.

According to Azure CTO Mark Russinovich, the most recent Windows 11 Insider Preview build is the first to include the memory-safe programming language Rust. Thurrott reports: "If you're on the Win11 Insider ring, you're getting the first taste of Rust in the Windows kernel," Russinovich tweeted last night. It's not clear which Insider channel he is referring to, however.

Regardless, that that was quick: Microsoft only went public with its plans to replace parts of the Windows kernel with Rust code in mid-April at its BlueHat IL 2023 security conference in Israel. At that event, Microsoft vice president David Weston said that "we're using Rust on the operating system along with other constructs" as part of an "aggressive and meaningful pursuit of memory safety," a key source of exploits. And it's not just the Windows kernel. Microsoft is bringing Rust to its Pluton security processor as well.

An anonymous reader shares this report from Tom's Hardware: When we think about Raspberry Pi, we normally picture single-board computers, but the Raspberry Pi Foundation was started to help kids learn about computers and it wants to help whether or not you own its hardware. The non-profit arm of Raspberry Pi this week released its new, browser-based code editor that's designed for young people (or any people) who are learning.

The Raspberry Pi Code Editor, which is considered to be in beta, is available to everyone for free right now at editor.raspberrypi.org. The editor is currently designed to work with Python only, but the organization says that support for other languages such as HTML, JavaScript and CSS is coming....

The Raspberry Pi Foundation already had a nice set of Python tutorials on its site, but it has adapted some of them to open sample code directly in the online editor....The Pi Foundation says that it plans to add a number of features to the Code Editor, including sharing and collaboration. The organization also plans to release the editor as an open-source project so anyone can modify it.
There's a pane showing your code's output when you click the "Run" button (plus a smaller pane for adding additional files to a project).

Tom's Hardware notes that "Since the entire programming experience takes place online, there's no way (at least right now) to use Python to control local hardware on your PC or your Raspberry Pi." But on the plus side, "If you create a free account on raspberrypi.org, which I did, the system will save all of your projects in the cloud and you can reload them any time you want. You can also download all the files in a project as a .zip file."

PINE64 has an update about their Star64 single-board computer with a quad-core RISC-V processor: it will be available on April 4th in two configurations: 4GB and 8GB LPDDR4 memory for $69.99 and $89.99: Let me just quickly reiterate the Star64 features:


- Quad core 64bit RISC-V
- HDMI video output
- 4x DSI and 4x CSI lates
- i2c touch panel connector
- dual Gigabit Ethernet ports
- dual-band WiFi and Bluetooth
- 1x native USB3.0 port, 3x shared USB2.0 ports
- PCIe x1 open-ended slot and GPIO bus pins (i2c, SPI and UART).
- The board also features 128M QSPI flash and eMMC and microSD card slots.


The board will be available in two different RAM configurations — with 4GB and 8GB LPDDR4 memory for $69.99 and $89.99 respectively. The Star64 store page ought to already be live when you read this, but will be listed as out of stock until the 4th.
Liliputing offers this summary: The Star64 is a single-board computer with a quad-core RISC-V processor, support for up to 8GB of RAM and up to 128GB of storage (as well as a microSD card reader). Developed by the folks at Pine64, it's designed to be an affordable platform for developers and hobbyists looking to get started with RISC-V architecture. Pine64 first announced it was working on the Star64 last summer...
Meanwhile, PINE64's Linux tablets, the PineTab2 and PineTab-V, will launch one week later on Tuesday, April 11th.

Other highlights from this month's community update: there's now a dedicated Debian with GNOME image with tailored settings for grayscale for their Linux-based "PineNote" e-ink tablets. ("Other OSes and desktop environments are being worked on too.")

And the update also includes photos of one user's cool 3D-printed replacement cases for their PinePhone featuring Tux the penguin.

"With an 8-core Rockchip RK3588S SoC, the Orange Pi 5 is leaps and bounds faster than the aging Raspberry Pi 4," writes Phoronix: With up to 32GB of RAM, the Orange Pi 5 is also capable of serving for a more diverse user-base and even has enough potential for assembling a budget Arm Linux developer desktop. I've been testing out the Orange Pi 5 the past few weeks and it's quite fast and nice for its low price point.

The Orange Pi 5 single board computer was announced last year and went up for pre-ordering at the end of 2022.... When it comes to the software support, among the officially available options for the Orange Pi 5 are Orange Pi OS, Ubuntu, Debian, Android, and Armbian. Other ARM Linux distributions will surely see varying levels of support while even the readily available ISO selection offered by Orange Pi is off to a great start....

Granted, the Orange Pi developer community isn't as large as that of the Raspberry Pi community or the current range of accessories and documentation, but for those more concerned about features and performance, the Orange Pi 5 is extremely interesting.
The article includes Orange Pi 5 specs:

• A 26-pin header
• HDMI 2.1, Gigabit LAN, M.2 PCIe 2.0, and USB3 connectivity
• A Mali G510 MP4 graphics processor, "which has open-source driver hope via the Panfrost driver stack."
• Four different versions with 4GB, 8GB, 16GB, or 32GB of RAM using LPDDR4 or LPDDR4X. "The Orange Pi 4GB retails for ~$88, the Orange Pi 5 8GB version retails for $108, and the Orange Pi 5 16GB version retails for $138, while as of writing the 32GB version wasn't in stock."

In 169 performance benchmarks (compared to Raspberry Pi 4 boards), "this single board computer came out to delivering 2.85x the performance of the Raspberry Pi 400 overall." And through all this the average SoC temperature was 71 degrees with a peak of 85 degrees — without any extra heatsink or cooling.

An anonymous reader quotes a report from Ars Technica: As spotted in Kevin Tofel's About Chromebooks blog, an updated version of the shortcut viewer in the Settings app -- first seen in October 2022 -- has the early makings of a shortcut changing and adding mechanism.

Clicking on a shortcut brings up a dialogue that allows you to, at the moment, add alternative shortcuts to common shortcuts for manipulating tabs, windows and desktops, system settings, accessibility, and other utilities. A small "lock" icon next to each suggests that you might also be able to unlock these shortcuts to remove or alter their defaults. A "Reset all shortcuts" button offers another hint. Sadly, none of the shortcuts you add seem to work for the moment, though the promise is there.

Long-time Slashdot reader wonkavader found a video on YouTube where, at the 2:50 mark, there's time-lapse footage of soldering paste magically melting into place. The secret? Many circuit boards include a grounded plane as a layer. This doesn't have to be a big unbroken expanse of copper — it can be a long snake to reduce the copper used. Well, if you run 9 volts through that long snake, it acts as a resistor and heats up the board enough to melt solder paste. Electronics engineer Carl Bugeja has made a board which controls the 9 volt input to keep the temperature on the desired curve for the solder.

This is an interesting home-brew project which seems like it might someday make a pleasant, expected feature in kits.
Hackaday is impressed by the possibilities too: Surface mount components have been a game changer for the electronics hobbyist, but doing reflow soldering right requires some way to evenly heat the board. You might need to buy a commercial reflow oven — you can cobble one together from an old toaster oven, after all — but you still need something, because it's not like a PCB is going to solder itself. Right?

Wrong. At least if you're Carl Bugeja, who came up with a clever way to make his PCBs self-soldering.... The quality of the soldering seems very similar to what you'd see from a reflow oven.... After soldering, the now-useless heating element is converted into a ground plane for the circuit by breaking off the terminals and soldering on a couple of zero ohm resistors to short the coil to ground.
It's an open source project, with all files available on GitHub. "This is really clever," tweeted Adrian Bowyer, inventor of the open source 3D printer the RepRap Project.

In the video Bugeja compares reflow soldering to pizza-making. (If the circuit board is the underlying dough, then the electronics on top are the toppings, with the solder paste representing the sauce that keeps them in place. "The oven's heat is what bonds these individual items together.")

But by that logic making a self-soldering circuit is "like putting the oven in the dough and making it edible."

Hackaday writes According to [Venn Stone], technical producer over at Linux GameCast, the Sony a5000 is still a solid option for those looking to shoot 1080p video despite being released back in 2014. But while the camera is lightweight and affordable, it does have some annoying quirks — namely an overlay on the HDMI output (as seen in the image above) that can't be turned off using the camera's normal configuration menu. But as it so happens, using some open source tools and the venerable telnet, you can actually log into the camera's operating system and fiddle with its settings directly.
A grassroots tool for unlocking Sony cameras apparently also unlocks developer options — including a telnet server on its WiFi interface. (There's a video of the whole procedure on Linux Gamecast Weekly's web site.)

Venn Stone (the podcast's technical producer/engineer) is apparently also a long-time Slashdot reader — and also describes himself on the podcast as "not a fan of articial software limitations."

And he calls this telnet-enabled tweak "the most hack-y thing I've done in recent memory" — even creating a playlist of 1990s hacker music to more fully enjoy the moment.

Microsoft is rolling out support for third-party widget development and new video calling functions for Chat from Microsoft Teams in its latest developer build of Windows 11. The new features in Preview Build 25217 are available for folks enrolled in the Windows Insider program. The Verge reports: Now, developers can create and test widgets that can be added to the Windows 11 widgets panel. New third-party widgets can only be tested locally on the latest Insider Preview build for now, but can later appear in the Microsoft Store for the shipping version of their apps once the build is formally released to the public. Microsoft says that Widgets can only be created for packaged Win32 apps at this time, but support for Progressive Web App (PWA) Widgets is planned as part of Microsoft Edge 108.

The Insider preview also includes a sneak peek (for a limited group of Insiders) at a new video calling experience for Chat from Microsoft Teams on Windows 11. When you open Chat from the taskbar, you'll soon be able to see a preview of your own video feed, allowing you to fix your appearance or spot any background issues before starting a call. Microsoft hopes to make this experience more broadly available in the coming months, but a 'small subset of users' will already have access to the feature as part of a sneak preview release. You can launch Chat from your Windows 11 taskbar yourself to check if you're one of the lucky few selected.

The Insider Preview Build 25217 also contains a few other feature updates, including improved cloud suggestions and integrated search suggestions for Simplified Chinese, and some design changes to the Microsoft Store. Now, the store makes it clearer if a game is included as part of Game Pass to spare you from accidentally purchasing a game you may have free access to. The Game Pass library is also getting a performance boost and some more simplified options.

PINE64's August update included photos of their first prototype for its upcoming Star64 single-board computer, "the first true RISC-V single-board computer from us...but as I wrote last month it certainly isn't the last RISC-V piece of hardware you'll be seeing from us." Just as a short recap: Star64 comes with a StarFive JH7110 64bit CPU sporting quad SiFive FU740 cores clocked at 1.5GHz. The SOC is equipped with BXE-2-32 from Imagination Technologies, which is said to be a solid mid-range GPU. Star64 will be available in two configurations — with 4Gb and 8GB of RAM, similarly to the Quartz64. Both hardware versions include USB 3.0 and a PCIe slot as well as two native Gigabit Ethernet NICs.... Along the long leading edges you'll find PCIe on one end and GPIO on the other. At one end of the board you'll find a digital video output, a double-stacked Gigabit Ethernet port and a 12V barrel plug for power. On the opposite side, you'll find 3x USB 2.0, 1x USB 3.0, an audio jack as well as a power button. There are also two U.FL ports for antennas — one for bluetooth and the other for WiFi....

The Star64 also has an MiPi display output complete with a touch panel (TP) input, a 12V power port, a CSI camera port and an eMMC slot. A micro SD card slot can be found at the bottom of the PCB. Similarly to the RockPro64 and Quartz64, the 12V port on the Star64 can be used for powering other hardware directly from the board — a popular example is powering one or multiple SSDs connected to a PCIe SATA adapter. I'll add that, at least in theory, the Star64 would make a great network-attached storage device because of its SoCs low thermals and idle power. I am looking forward to seeing NAS-focused Linux or BSD* OSes available for the board.

Speaking of software, efforts to support the SoC in Linux have already begun. I've been told that both Debian and Fedora are already being ported to the StarFive JH7110, which is great news. We are certain that many other OSes will follow swiftly — especially once we start delivering the Star64 to interested developers. On the subject of availability: the Star64 will be available in a few weeks time, and will initially be available to developers. Given the interest in the Star64's and the SoC powering I hope to see functional distributions available for the board soon after launch.
The announcement also included an update on their PinecilV2 smart mini portable soldering iron (built with a 32-bit RISC-V SoC). "The Pinecil V2 landed earlier this month and sold out almost instantly. The next production run of the ought to be available soon however..."

"While Valve has yet to actually release a proper ISO for SteamOS 3 used on the Steam Deck, others have been taking it into their own hands to provide," reports GamingOnLinux, "like with the new HoloISO.

"This is possible, since 99% of what SteamOS uses is open source (not the Steam client though)..." So people can easily hack away at it to do whatever they want. [HoloISO] is not exactly the same as SteamOS 3 but it's probably the closest I've seen yet, with the main packages coming direct from Valve with "zero possible edits" the developer says.
It's described as a "first beta release."

Neowin supplies some context: Back in early March, Valve released the Steam Deck recovery image for Deck users who need to get back to a factory state. When it was released, many of us over at the Steam OS subreddit did the first thing any reasonable enthusiast would do and tried installing it on a standard PC. The results of this approach were mixed, and only partial successes were achieved. Then HoloISO happened....

The first release, called 'Ground Zero', was released today and allows users to install Steam OS on any machine. But there are some things you need to know before installing this for yourself....
There's a bunch of caveats, but the article still concludes that "If you're team red and you want to give this a shot, head over to the project's Github page to read more and download."

Microsoft's latest Windows 11 test build is another substantial one, adding two important features: payment information, and a new security feature called Smart App Control that will watch over new apps and games that you add to your PC. PCWorld reports: Microsoft released Windows 11 Insider Preview Build 22567 for the Dev Channel on Wednesday with other changes, tooâ"including a tweak to Windows Update, so that now you can configure your PC to turn on an update when renewable energy is at its most plentiful. (Remember, code that Microsoft tests within the Dev Channel may make its way to your PC eventually -- or not.)

Asking for credit-card information within Windows isn't that startling, as you've probably already entered payment information into the Microsoft ecosystem either for buying apps or movies on the Microsoft Store app or for making similar purchases via your Xbox. Still, those transactions are normally performed via your Microsoft Account web page, which manages all of that online and behind the scenes. (You can reach them via the Windows 11 Settings > Accounts > Your Microsoft account.) Microsoft considers the additional credit-card info as part of the subscription option it added last month. Now, if your subscription risks falling through because of an expired credit card, Microsoft will alert you. Conceptually, however, it implies that your PC is as much a tool to make purchases as it is to simply work and game.

Another interesting addition is what Microsoft calls Smart App Control, or SAC. Microsoft describes it as a "new security feature for Windows 11 that blocks untrusted or potentially dangerous applications." What those applications are, apparently, is up to Microsoft. And yes, there's always a concern that SAC would flag otherwise innocuous applications that it simply hasn't seen before. But Microsoft is gently easing SAC onto your PC. For one thing, you'll need to perform a clean install to enable it. For another, SAC won't immediately insert itself. Other tweaks and changes include the ability to have Windows update your PC when clean energy is more commonly available (via Microsoft's partners electricityMap or WattTime) and better integration between your Android phone and PC via Windows 11 OOBE (Out of the Box Experience).

Additionally, "Microsoft now offers wider availability of speech packs to improve transcription, the ability to choose a mic for dictation/ transcription, and the ability to mute your speakers by simply clicking the volume icon in the hardware indicator for volume," reports PCWorld.

Wired reports on 22-year-old Sam Zeloof, who builds semiconductors in his family's New Jersey garage, "about 30 miles from where the first transistor was made at Bell Labs in 1947." With a collection of salvaged and homemade equipment, Zeloof produced a chip with 1,200 transistors. He had sliced up wafers of silicon, patterned them with microscopic designs using ultraviolet light, and dunked them in acid by hand, documenting the process on YouTube and his blog. "Maybe it's overconfidence, but I have a mentality that another human figured it out, so I can too, even if maybe it takes me longer," he says... His chips lag Intel's by technological eons, but Zeloof argues only half-jokingly that he's making faster progress than the semiconductor industry did in its early days. His second chip has 200 times as many transistors as his first, a growth rate outpacing Moore's law, the rule of thumb coined by an Intel cofounder that says the number of transistors on a chip doubles roughly every two years.

Zeloof now hopes to match the scale of Intel's breakthrough 4004 chip from 1971, the first commercial microprocessor, which had 2,300 transistors and was used in calculators and other business machines. In December, he started work on an interim circuit design that can perform simple addition....

Garage-built chips aren't about to power your PlayStation, but Zeloof says his unusual hobby has convinced him that society would benefit from chipmaking being more accessible to inventors without multimillion-dollar budgets. "That really high barrier to entry will make you super risk-averse, and that's bad for innovation," Zeloof says.

The Register reports on a unique response to CES: Six right-to-repair advocates assembled on Friday morning to present Repair.org's second annual Worst in Show Awards, a selection of the "the least private, least secure, least repairable, and least sustainable gadgets at CES."

In a presentation streamed on YouTube, author and activist Cory Doctorow presided over the condemnation session. He said that he has been attending the Consumer Electronics Show for decades and vendors will gladly enumerate the supposed benefits of their products. "But what none of those people will ever do is tell you how it will fail," said Doctorow. "And that's kind of our job here today, to talk about the hidden or maybe not so hidden and completely foreseeable failure modes of these gadgets."

Kyle Wiens, co-founder of iFixit, gave the new Mercedes EQS EV the award for the worst product in terms of repairability. Showing a slide of the warning screen the car presents to its driver, he said, "You cannot open the hood of the car. It is locked, warning of accident, warning of injury if you open the hood. Mercedes' perspective is, 'Hey, this is an electric car. There's nothing the owner needs to do under the hood of this car."

Wiens said this is not the first time Mercedes has gone down this road, noting that a few years ago the company removed the dipstick from its C-class vehicles, arguing that only an authorized technician should change the oil.

"So this is everything that is wrong with the future," he said.
Some other higlights (via the Register)... Nathan Proctor, national campaign director for public interest non-profit USPIRG, gave the "worst in class for the environment" award to Samsung's new NFT Aggregation Platform, which he described as "a way to buy, sell and display your NFT artwork from your huge ginormous OLED Samsung TV."

Proctor added "If you don't know what an NFT is, I am honestly jealous of your life," calling it "sort of like a Beanie Baby craze for crypto tech bros — if Beanie Babies required massive continual energy consumption on a warming planet to remain corporeal."

And the Community Choice poll for Worst in Show went to John Deere — presumably for fighting right-to-repair laws in every single state legislature — while the tractor companywas also recognized by Paul Roberts, founder of securerepairs.org, for its industry-lagging bad outreach to the security community.

A U.S. advocacy group called The Repair Association is urging Americans to demand protections for their right to repair from the country's consumer protection agency.

"Tell the FTC: People just want to fix their stuff!" argues a page urging concerned U.S. citizens to sign an online petition (shared by long-time Slashdot reader Z00L00K).

The petition asks the FTC to...

• Enforce the law against companies who use illegal tying arrangements to force consumers to purchase connected repair services.

• Enforce the law against companies who violate the Magnuson Moss Warranty Act by voiding warranties when a consumer fixes something themselves or uses third-party parts or repair services.

• Enforce the law against companies who refuse to sell replacement parts, diagnostic and repair tools, or service information to independent repair providers.

• Publish new guidance on unfair, deceptive, and abusive terms in end user license agreements (EULAs) that: restrict independent or self repair; restrict access to parts and software; prohibit the transfer of user licenses; that and that purport to void warranties for independent or self repair.

• Issue new rules prohibiting exclusivity arrangements with suppliers, customers, and repair providers that exclude independent repair providers and suppress competition in the market for repair services.

• Issue new rules prohibiting companies from deceiving customers by selling products which cannot be repaired without destroying the device or cannot be repaired outside of the company's own service network, without disclosing that fact at the point of sale.

The New York Times reports: Along with baking and jigsaw puzzles earlier in the pandemic, model trains are among the passions being rediscovered while people are cooped up indoors. Several companies that make trains are reporting jumps in sales. For many people, the chance to create a separate, better world in the living room — with stunning mountains, tiny chugging locomotives and communities of inch-high people where no one needs a mask — is hard to resist.

"Outside, there is total chaos, but inside, around my little train set, it is quiet, it is picturesque," said Magnus Hellstrom, 48, a high school teacher in Sweden, who has indulged in his hobby while working from home during lockdowns.

"It's a little piece of a perfect world," he said.
The Times visits Märklin, the 162-year-old German maker of model trains, whose engines now include "tiny speakers that reproduce scores of digital chugging noises and whistles (recorded, if possible, from the original), and interior and exterior lights that can be controlled separately... Real steam coming out of the steam locomotives has been a feature for years." The company's owner tells the newspaper "What's really changed during the last 20 years is the focus on truly replicating the original." The trains can be controlled by computer console or by a phone app, with different trains on the same track going different speeds or traveling different circuits. Märklin even added the option of controlling the trains via train engineer simulator software, allowing devotees to control their little model train as though they were sitting in the engineer's chair.

"It is a traditional toy that through digital functions, like sound and light, has become more and more like a real train," said Uwe Müller, who was a product manager at Märklin for 15 years and now runs the Märklineum, the company's museum.
Just 12 years ago the company had declared bankruptcy. But now one 64-year-old employee (who's assembled models trains for the company for over 38 years) tells the Times "We're booming so much it's hard to keep up."

"At the recent tinyML Summit 2021, Raspberry Pi co-founder Eben Upton teased the future of 'Pi Silicon'," writes Tom's Hardware, adding "It looks like machine learning could see a massive improvement thanks to Raspberry Pi's news in-house chip development team..." Raspberry Pi's in-house application specific integrated circuit team are working on the next iteration, and seems to be focused on lightweight accelerators for ultra low power machine learning applications. During Upton's talk at 40 minutes the slide changes and we see "Future Directions," a slide that shows three current generation 'Pi Silicon' boards, two of which are from board partners, SparkFun's MicroMod RP2040 and Arduino's Nano RP2040 Connect. The third is from ArduCam and they are working on the ArduCam Pico4ML which incorporates machine learning, camera, microphone and screen into a the Pico package.

The last bullet point hints at what the future silicon could be. It may come in the form of lightweight accelerators possibly 4-8 multiply-accumulates (MACs) per clock cycle.

There's 29 hours left in a Kickstarter campaign to fund "an open source, Linux-based, highly modular, customizable portable computer kit that accommodates anything from a Raspberry Pi to a Ryzen x86 4x4 single-board computer and more," writes READY!100: Reminiscent of 1980s executive portable computers, the READY! 100 is fully modern with 12 input output ports and 4 antenna ports. Perfect for hackers, ham radio operators, and audio/video folks, it can even be used with external graphics cards.
Engadget hailed it as "a Raspberry Pi enclosure for cyberpunk enthusiasts." Thanks to their diminutive size and low-power consumption, single-board computers like the Raspberry Pi can come in all shapes and sizes. We've seen DIY enthusiasts like Guy Dupont put a $10 Raspberry Pi Zero W into the shell of a 2004 iPod Classic to create a device that can access Spotify. But few are as cool as this recent Kickstarter project we spotted from a Toronto-based company called Ready! Computer Corporation.

The company's Ready! Model 100 is essentially a case for your single-board computer that includes a mechanical keyboard, stereo speakers, a touchscreen display and enough I/O ports to connect almost anything you need. The enclosure allows you to fit an SBC that's about the size of a 4x4 Intel NUC board. Oh, and you can carry it around with a guitar strap.

Basically, it allows you to build the cyberdeck of your dreams.

Thanks to the hard work of the SwitchRoot team, it's now possible to enjoy an Android 10-based LineageOS 17.1 port on your Nintendo Switch console. XDA Developers reports: The Android 10 release is based on the LineageOS 17.1 build for the NVIDIA SHIELD TV and brings many improvements over the previous release, including a much-needed deep sleep mode so the OS doesn't murder your console's battery life. It's also generally faster and more responsive than the previous Android 8.1 Oreo version, according to the SwitchRoot team.

The ROM comes in two flavors: a Tablet build that offers a standard Android UI with support for all apps and an Android TV build that supports both docked and undocked use cases but has more limited app support. The former is recommended if you primarily use your Nintendo Switch while undocked, while the latter will offer a much-better docked experience. As for bugs and broken things, the developer says games built for the SHIELD (Half-Life 2, Tomb Raider, etc.) aren't supported, and you might notice some stuttering with Bluetooth audio. Some apps also may not support the Joy-Con D-Pad.

In order to install this build, you'll need an RCM-exploitable Nintendo Switch, a USB-C cable, a high-speed microSD card (formatted to FAT32), and a PC. If you already have the Android 8.1 Oreo build installed on your SD card, just make sure to back up your data before installing the Android 10 build, as flashing this new ROM will wipe all data. After installing the ROM itself, be sure to flash the Google Apps package, Alarm Disable ZIP, and Xbox Joycon Layout ZIP if you use an Xbox controller. You can download LineageOS 17.1 for Nintendo Switch here.

"A company says it has listed the first 3D printed house in the United States for sale," reports CNN. "This is the future, there is no doubt about it," says Kirk Andersen, the director of operations at SQ4D Inc.

SQ4D uses automated building methods, or 3D printing, to build structures and homes... The company can set up its Autonomous Robotic Construction System at a build site in six to eight hours. It then lays concrete layer by layer, creating footing, the foundation of a house and the interior and exterior walls of the structure... "The cost of construction is 50% cheaper than the cost of comparable newly-constructed homes in Riverhead, New York, and 10 times faster," said Stephen King, the Zillow Premier agent who has the 3D house listing...

"I want people to not be afraid of automation...it is just a different tool and different method. But it's still the same product; we are still building a house at the end of the day," says Kirk Andersen, the director of operations at SQ4D...

"We can make things more affordable and safer. We can use the technology to tackle homelessness, and aid in disaster relief in an eco-friendly way," Andersen said.

Microsoft has made available two different Windows 10 test builds today, one of which includes the promised x64 app emulation for Arm, among other features. ZDNet reports: The RS_Prerelease build 21277 -- which ultimately is expected to be designated as the "Cobalt" branch -- includes the features Microsoft had previously been testing but removed at the end of October. This includes the updated emoji picker, redesigned touch keyboard, voice typing, theme-aware splash screens and more. It also provides the aforementioned Arm emulation support. Currently, Windows on Arm natively supports Arm apps, including ARM64 versions. But so far, only 32-bit Intel (x86) apps are supported in emulation. This lack of x64 emulation has limited the number of apps that can run on Windows on Arm devices, since apps that are 64-bit only have only been available on Windows on Arm (WoA) devices if and when developers created native versions of them. As of now, these x64 Arm apps also can run in emulation. More details on the x64 Arm emulation preview functionality are in this Microsoft post.

AmiMoJo quotes SlashGear: Remember the Pebble smartwatch? Despite being officially discontinued and several years old at this point, there are still some diehard fans out there keeping the hardware alive, and a team called Rebble Alliance plays an important part in this.

Whereas the web services for Pebble watches used to come from Pebble Technology Corp., they now come (unofficially) from Rebble, which has announced a new initiative called Rebble Grants... Rebble Alliance is, as explained by iFixit in an editorial last year, a group of former Pebble employees like Katharine Berry, as well as enthusiasts who are working hard to keep the defunct hardware operational. Key to this is the Rebble web services, which includes a replacement cloud infrastructure that was coded by Berry over the course of a couple of weeks...

The team says they've been saving some of the funds received from running the Rebble web services and that they plan to invest $25,000 into a variety of Pebble-centric projects.

Today, Mozilla launched the updated Firefox Android app with a version that many thought was a beta because it was full of bugs and UI issues. According to The Register, this was a deliberate software release and is the new version of Firefox for Android, which is set to hit the UK today, August 25, and the U.S. on the 27th. From the report: A Reg reader yesterday alerted us to an August 20 version bump that was causing so many problems, our tipster thought it was a beta that had gone seriously awry. "To sum it up, on 20th of August, Firefox 79 was unexpectedly forced on a large batch of Firefox 68 Android users without any warning, way to opt out or roll back," our reader reported. "A lot got broken in the process: the user interface, tabs, navigation, add-ons." Meanwhile, the Google Play store page for the completely free and open-source Firefox has a rash of one-star reviews echoing similar complaints: after the upgrade, little seemed to work as expected. "This is the worst 'upgrade' I've ever experienced," said netizen Martin Lindenmayer. "My main gripe is that there is no back button (to return to your previous page) anymore."

What's happened is this: the last stable version of Firefox for Android was version 68, released in 2019. For over a year, Mozilla has been working on an overhaul of its browser in a project code-named Fenix. Moz has slowly rolled out the result of its work to netizens in preview and beta form -- and since the end of July, as a proper release: version 79. This new stable version is what appeared on people's devices. As well as changes to the user interface and many new features that have thrown some users, it is also missing support for all extensions. In fact, by last count, only nine add-ons are supported so far, though this is expected to increase over time. The browser has also adopted Mozilla's GeckoView engine. If you accidentally updated the app and would like to roll back the update, you won't be able to. "[O]nce you've upgraded to the new browser, you won't be able to return to the old browser," says Mozilla.

For more information about the upgrade process, you can check out the browser's FAQ page.

At Build 2020 today, Microsoft gave developers a slew of new tools to coax them into using Windows over macOS or Linux. From a report: Windows Terminal is now out of preview for enterprises, and Windows Subsystem for Linux (WSL) 2 is getting support for GPUs, Linux GUI apps, and a simplified install experience. Microsoft even released a Windows Package Manager in preview. Windows 10 runs on 1 billion monthly active devices (PCs, Xbox One consoles, and HoloLens devices), making it a massive platform for developers to target. [...] Microsoft today released Windows Terminal 1.0, which means it is stable for enterprise use. The open source application features multiple tabs, panes, tear-away windows, shortcuts, Unicode and UTF-8 character support, emojis, ligatures, extensions, GPU-accelerated text rendering engine, and custom themes, styles, and configurations. Windows Terminal is for users of PowerShell, Cmd, WSL, and other command-line tools. Microsoft also unveiled WSL improvements today, including support for GPUs, Linux GUI apps, and a simplified install experience. WSL is a compatibility layer for running Linux binary executables natively on Windows. Microsoft first shared it was working on WSL 2 a year ago at Build 2019. WSL 2 is slated to arrive in the next major Windows 10 update coming later this month (brilliantly called the Windows 10 May 2020 Update), but it won't have these new features. In the second half of the year, WSL 2 will get support for GPU compute workflows.

An anonymous reader quotes a report from The Wall Street Journal: Taiwan Semiconductor Manufacturing Co. (TSMC), the world's largest contract manufacturer of silicon chips, is set to announce plans to build an advanced chip factory in Arizona (Warning: source paywalled; alternative source) as U.S. concerns grow about dependence on Asia for the critical technology. The plans come as the Trump administration has sought to jump-start development of new chip factories in the U.S. due to rising fears about the U.S.'s heavy reliance on Taiwan, China and South Korea to produce microelectronics and other key technologies.

TSMC is expected to announce the plans as soon as Friday after making the decision at a board meeting on Tuesday in Taiwan, according to people familiar with the matter. The factory could be producing chips by the end of 2023 at the earliest, they said, adding that both the State and Commerce Departments are involved in the plans. TSMC's new plant would make chips branded as having 5-nanometer transistors, the tiniest, fastest and most power-efficient ones manufactured today, according to a person familiar with the plans. TSMC just started rolling out 5-nanometer chips for customers to test at a factory in Taiwan in recent months. It is unclear how much TSMC has budgeted or if it would get financial incentives from the U.S. to build. A factory capable of making the most advanced chips would almost certainly cost more than $10 billion, according to industry executives.

Microsoft is planning to fully integrate Linux file access into the built-in File Explorer. The Verge reports: A new Linux icon will be available in the left-hand navigation pane in File Explorer, providing access to the root file system for any distros that are installed in Windows 10. The icon that will appear in File Explorer is the famous Tux, the penguin mascot for the Linux kernel. Microsoft is testing the Linux File Explorer integration in a new build of Windows 10 that's available for testers today. Previously, Windows 10 users would have to manually navigate to a UNC path to get access to Linux files from the Windows Subsystem for Linux (WSL). If you have WSL enabled, then the Tux will appear in File Explorer, and Microsoft is now seeking feedback on the integration before it's finalized as part of a future Windows 10 update. The software maker will ship this update to all Windows 10 users later this year.

schwit1 quotes CNN's report on a software engineer who really loves Star Wars costumes:
"I kind of incorporated all of the things that I've learned in 3-D printing and DIY into this project," said Nils Rasmusson. Over the course of nine months, he printed the suit and put it together. "I had to figure out — how do you put all of these pieces together? There's no tutorial or instructions on this," he said.

The helmet alone is made up of 19 different pieces fabricated on the printer. Rasmusson said he used five printers, humming for about 400 to 600 hours, to fabricate the suit out of plastic filament.

It's even bulletproof. His friend works for a company that bulletproofs cars...

Electronic component distributor Digi-Key will be producing a small manufacturing run of the "open hardware" ereader from the Open Book Project, reports Gizmodo: The raw hardware isn't as sleek or pretty as devices like the Kindle, but at the same time there's a certain appeal to the exposed circuit board which features brief descriptions of various components, ports, and connections etched right onto the board itself for those looking to tinker or upgrade the hardware. Users are encouraged to design their own enclosures for the Open Book if they prefer, either through 3D-printed cases made of plastic, or rustic wooden enclosures created using laser cutting machines. With a resolution of just 400x300 pixels on its monochromatic E Ink display, text on the Open Book won't look as pretty as it does on the Amazon Kindle Oasis which boasts a resolution of 1,680x1,264 pixels, but it should barely sip power from its built-in lithium-polymer rechargeable battery -- a key benefit of using electronic paper.

The open source ereader -- powered by an ARM Cortex M4 processor -- will also include a headphone jack for listening to audio books, a dedicated flash chip for storing language files with specific character sets, and even a microphone that leverages a TensorFlow-trained AI model to intelligently process voice commands so you can quietly mutter "next!" to turn the page instead of reaching for one of the ereader's physical buttons like a neanderthal. It can also be upgraded with additional functionality such as Bluetooth or wifi using Adafruit Feather expansion boards, but the most important feature is simply a microSD card slot allowing users to load whatever electronic text and ebook files they want. They won't have to be limited by what a giant corporation approves for its online book store, or be subject to price-fixing schemes which, for some reason, have still resulted in electronic files costing more than printed books.

McGruber writes: In a reply to a Twitter post, Raspberry Pi Foundation's CEO Eben Upton announced that they have sold their thirty-millionth Raspberry Pi.
"We don't get sales returns from our licensees until month end," Upton acknowledged in a later tweet, but "at the end of November, we were at 29.8Mu, with a monthly run rate of 500-600ku..."

PC Magazine's "tech nerd" Whitson Gordon writes that "Once you start using a smart speaker to set reminders, play the news, or turn the lights on, it's hard to go back."

But if you want the convenience of voice control without the data-collecting tech giant behind the scenes, an open-source project called Mycroft is a great alternative. And you can run it right on a Raspberry Pi.

Mycroft is a free, open-source voice assistant designed to run on Linux-based devices... Mycroft has been around for quite a few years, but it's recently gained a bit more notoriety thanks to privacy concerns surrounding data collection at Amazon and Google. Unlike those assistants, Mycroft only collects data if you opt in during setup. And for the users who do opt in, Mycroft promises never to sell your data to advertisers or third parties -- instead, it only uses it to help developers improve the product. Mycroft even uses the privacy-focused DuckDuckGo as its search engine instead of Google when you ask for information.

Mycroft makes its own smart speaker called the Mark I, though it's currently sold out with a new Mark II (video here) on the way. However, since the project is open-source, you can install Mycroft on just about any Linux machine, including the Raspberry Pi (thanks to a pre-made build called Picroft). Using Mycroft on the Pi is free, but you can also subscribe to a $1.99-per-month plan to help support its development -- you'll even get a few goodies, like other voices that sound more lifelike than the default robotic voice.

Long-time Slashdot reader ttsiod works for the European Space Agency as an embedded software engineer. He writes: After reading an interesting article from an NVIDIA engineer about how he used a dirt-cheap field-programmable gate array board to code a real-time ray-tracer, I got my hands on the same board -- and "compiled" a dual-core SPARC-compatible CPU inside it... Basically, the same kind of design we fly in the European Space Agency's satellites.

I decided to document the process, since there's not much material of that kind available. I hope it will be an interesting read for my fellow Slashdotters -- showcasing the trials and tribulations faced by those who prefer the Open-Source ways of doing things... Just read it and you'll see what I mean.
This is the same Slashdot reader who in 2016 reverse engineered his Android tablet so he could run a Debian chroot inside it. "Please remember that I am a software developer, not a HW one," his new essay warns.

"I simply enjoy fooling around with technology like this."

"Biohackers took one small but important step toward the science fiction dystopia depicted in William Gibson's Johnny Mnemonic," reports The Parallax, in an article shared by a Slashdot reader: The Four Thieves Vinegar biohacking collective has not figured out how to precisely mimic the memory data transfer scenario Gibson conjured, but it has built a device to enable people to store and transfer data wirelessly in their bodies. Using off-the-shelf parts and focused efforts, the biohacking group has designed and built a networked hard drive, coated in a biosafe resin, to be subcutaneously implanted in the human body. It's powered by an external battery that connects to the device via an induction coil, and its storage capacity is limited only by the size of the microSD card it contains. Michael Laufer, who founded Four Thieves Vinegar, calls it the Pegleg.

In the small hours of August 8, in an operating room within the small house, two patients received the second version of the Pegleg implant, which Laufer says is the world's first subcutaneous networked drive... To make Pegleg v2, Laufer and his team removed from the Raspberry Pi both Micro USB connectors (one for power, one for data), the Mini HDMI connector, and the camera connector. They then soldered on a second Wi-Fi chip to enable it to transfer data to another Pegleg and allow other devices to connect to it, as well as an induction coil to enable it to be powered by a wireless battery resting in a contiguous sports armband or pants pocket. They enabled Bluetooth for future functionality, inserted a 512GB microSD card for storage, and updated the firmware. Finally, they coated the hacked device in a biocompatible acrylic resin to prevent it from interacting with the recipient's body and to diffuse the heat it emanates.

At 11:44 a.m. on the same day, Laufer -- an implant newbie who has three small tattoos but no piercings -- took a seat in the surgical room... During the procedure, Laufer passed out for a few seconds and vomited a little bit. But 32 minutes later, he had a functional "Pegleg" implant.

option8 ((Slashdot reader #16,509) writes: TL;DR: Mining Bitcoin on a 1MHz 8-bit processor will cost you more than the world's combined economies, and take roughly 256 trillion years.
"But it could happen tomorrow. It's a lottery, after all," explains the blog post (describing this mad scientist as a hardware hacker and "self-taught maker", determined to mine bitcoin "in what must be the slowest possible way. I call it 8BITCOIN....")

There's also a Twitch.TV stream, with some appropriate 8-bit music, and the blog post ends by including his own bitcoin address, "If you feel like you absolutely must throw some money at me and this project."

"Upon doing some research, I found that, not only were other 8-bit platforms being put to the task, but other, even more obscure and outdated hardware. An IBM 1401 from the 1960s, a rebuilt Apollo Guidance Computer, and even one deranged individual who demonstrated the hashing algorithm by hand. It turns out, those examples all come from the same deranged individual, Ken Shirriff."

In comments submitted to America's Federal Trade Commission, Microsoft says repairing its devices could jeopardize protections from the Trusted Platform Module (TPM) security chip.

"Don't believe them," argues a group of information security professionals who support the right to repair. Slashdot reader chicksdaddy quotes their report: The statement was submitted ahead of Nixing the Fix, an FTC workshop on repair restrictions that is scheduled for mid-July... "The unauthorized repair and replacement of device components can result in the disabling of key hardware security features or can impede the update of firmware that is important to device security or system integrity," Microsoft wrote... "If the TPM or other hardware or software protections were compromised by a malicious or unqualified repair vendor, those security protections would be rendered ineffective and consumers' data and control of the device would be at risk. Moreover, a security breach of one device can potentially compromise the security of a platform or other devices connected to the network...."

As we know: Firms like Microsoft, Lexmark, LG, Samsung and others use arguments like this all the time and then not too subtly imply that their authorized repair professionals are more trustworthy and honest than independent competitors. But that's just hot air. They have no data to back up those assertions and there's no way that their repair technicians are more trustworthy than owners, themselves...

There's nothing inherent in repair or the things called for in right to repair laws like providing diagnostic software, diagnostic codes, schematics and replacement parts that puts the integrity of the TPM or the trust model it anchors at risk. Nor does the TPM require that the devices it secures remain pristine: using the same hardware and software configuration as when they were sold by the OEM. After all, TPMs are in Dell computers. Dell makes diagnostic software and diagnostic codes and schematics available for their hardware and I haven't heard Microsoft or anybody else suggest that a TPM on a repairable Dell laptop is any less secure than the TPM on an unrepairable Microsoft Surface.

The Chromium-powered Edge browser is now available on both Windows 7 and Windows 8 for testing today. The Verge reports: The release comes two months after Chromium Edge first debuted on Windows 10, and a month after it appeared on macOS. Microsoft is releasing the daily Canary builds initially, and plans to support the weekly Dev channel "soon." You can download the installer over at Microsoft's Edge Insider site. "You will find the experience and feature set on previous versions of Windows to be largely the same as on Windows 10, including forthcoming support for Internet Explorer mode for our enterprise customers," explains a Microsoft Edge team blog post. While most features will be the same, dark mode is missing and Microsoft says there is no support for AAD sign-in.
