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."
