Sylphide OS: a general-purpose OS for microcontroller-based computers
projects.freehackers.org53 points13 comments
Sylphide OS is an attempt to bring a familiar, graphical home-computer experience to modern microcontroller boards that are too constrained to run Linux. It targets systems with keyboard and mouse, a standard VGA or HDMI display driven by a framebuffer, and storage; networking is useful but optional. The project treats these machines as a distinct form of retrocomputing: they use inexpensive, modern components, yet their limited memory and graphics capabilities resemble computers of the 1980s and 1990s. Its open-hardware approach includes KiCad board designs as well as software, and the system is intended to adapt to platforms with widely varying resources.
The software builds on FreeRTOS, adding device drivers, graphics, a desktop interface, and programs in a mostly C and carefully limited C++ codebase. Current targets include the Olimex ESP32-P4-PC, a Raspberry Pi Pico 2-based design, FabGL hardware, and a Linux-hosted emulator. At version 0.1, the priority is a stable framework and working drivers rather than a complete operating system: it already offers configurable platform support, framebuffer rendering, fonts and bitmaps, and a desktop with menus, windows, icons, and a hardware-information panel. Persistent storage, networking, reusable interface widgets, and loading external programs are planned but not yet available. The project is therefore most relevant to readers interested in MCU hardware, embedded graphics, or building a compact computer with a retro-style interface.

Tesla caught altering specs following rear suspension collapse reports
Tesla’s Model Y L owner manuals now list lower vehicle height and ground-clearance figures, differing from specifications still shown on Tesla’s China site. The changes surfaced amid owner reports of rear suspension collapse, but Tesla has not explained whether they reflect a technical or hardware change. (carnewschina.com)

Grace Blackwell needs a new scheduler: 27% more usable GPUs from the same racks
SkyPilot says its topology-aware scheduler can deliver 27% more usable GPUs from the same NVL72 racks by keeping multi-node jobs on the rack’s NVLink fabric. It also recovers jobs in place after GPU failures and defragments clusters to preserve rack-local capacity. (skypilot.ai)
Mexico is a showroom for electric vehicles you can't buy in the U.S.
Mexico’s growing market for Chinese electric vehicles offers feature-rich cars at prices far below comparable U.S. models, while tariffs and trade barriers keep them out of the United States. Chinese brands are gaining ground globally, and experts say their vehicles or technology will eventually reach American buyers. (washingtonpost.com)
