The blog OMG Ubuntu reports that a new version of the Raspberry Pi 4 Model B has been (quietly) introduced. "The key difference? It now uses a dual-RAM configuration." The Raspberry Pi 4 Model B (PCB 13a) adopts a dual-RAM configuration to 'improve supply chain flexibility' and manufacturing efficiency, per a company product change notice document. Earlier versions of the Raspberry Pi 4 use a single RAM chip on the top of the board. The new revision adds a second LPDDR4 chip to the underside, with a couple of passive components also moved over... In moving to a dual-chip layout, Raspberry Pi can combine two smaller — and marginally cheaper — modules to hit the same RAM totals amidst fluctuating component costs... This change will not impact performance (for better or worse). The Broadcom BCM2711 SoC has a 32-bit wide memory interface so the bandwidth stays identical; this is not doubling the memory bus, it's just a physical split, not a logical one. Plus, the new board is fully compatible with existing official accessories, HATs and add-ons. All operating systems that support the Pi 4 will work, but as the memory setup is different a new version of the boot-loader will need to be flashed first.

Four economists across Central European University, Bielefeld University and the Kiel Institute have built a general equilibrium model of the open-source software ecosystem and concluded that vibe coding -- the increasingly common practice of letting AI agents select, assemble and modify packages on a developer's behalf -- erodes the very funding mechanism that keeps open-source projects alive. The core problem is a decoupling of usage from engagement. Tailwind CSS's npm downloads have climbed steadily, but its creator says documentation traffic is down about 40% since early 2023 and revenue has dropped close to 80%. Stack Overflow activity fell roughly 25% within six months of ChatGPT's launch. Open-source maintainers monetize through documentation visits, bug reports, and community interaction. AI agents skip all of that. The model finds that feedback loops once responsible for open source's explosive growth now run in reverse. Fewer maintainers can justify sharing code, variety shrinks, and average quality falls -- even as total usage rises. One proposed fix is a "Spotify for open source" model where AI platforms redistribute subscription revenue to maintainers based on package usage. Vibe-coded users need to contribute at least 84% of what direct users generate, or roughly 84% of all revenue must come from sources independent of how users access the software.

jeditobe writes: ReactOS, the open-source operating system aimed at binary compatibility with Windows, recently marked its 30th anniversary. Launched in 1996, ReactOS has focused on providing a free alternative to Windows, with compatibility for Windows applications and drivers. Though still in development, it has made significant progress in recent years, including improvements to USB support, better hardware compatibility, and enhanced performance with the release of version 0.4.15. The upcoming 0.4.16 release is set to introduce UEFI support, KMDF and WDDM graphics driver support, marking a major step forward in ReactOS's development.

Brax Technologies just announced "a privacy-focused alternative to locked-down tablets" called open_slate that can double as a consumer tablet and a Linux-capable workstation on ARM. Earlier Brax Technologies built the privacy-focused smartphone BraX3, which co-founder Plamen Todorov says proved "a privacy-focused mobile device could be designed, crowdfunded, manufactured, and delivered outside the traditional Big Tech ecosystem." Just as importantly, BraX3 showed us the value of building with the community. The feedback we received — what worked, what didn't, and what people wanted next — played a major role in shaping our direction going forward. Today, we're ready to share the next step in that journey... They're promising their "2-in-1" open_slate tablet will be built with these guiding principles: Modularity beyond repairability". ("In addition to a user-replaceable battery, it supports an M.2 expansion slot, allowing users to customize storage and configurations to better fit their needs.") Hardware-level privacy and control, with physical switches allowing users to disable key components like wireless radios, sensors, microphones, and cameras. Multi-OS compatibility, supporting "multiple" Android-based operating systems as well as native Linux distributions. ("We're working with partners and the community to ensure proper, long-term OS support rather than one-off ports.") Longevity by design — a tablet that's "supported over time" Brax has already created an open thread with preliminary design specs. "The planned retail price is 599$ for the base version and 799$ for the Pro version," they write. "We will be offering open_slate (both versions) at a discount during our pre-order campaign, starting as low as 399$ for the base version and 529$ for the Pro version for limited quantities only which may sell out in a day or two from launching pre-orders... "Pre-orders will open in February, via IndieGoGo. Make sure to subscribe for notifications if you don't want to miss the launch date." Thanks to long-time Slashdot reader walterbyrd for sharing the news.
