CH32V003: The 10-Cent RISC-V Chip Dividing the Community
The CH32V003, a ten-cent RISC-V microcontroller, is at the center of a response from an embedded engineer in Trinidad and Tobago to the harshest article the architecture has received in years. The debate exposes a real tension between design elegance and hardware access outside the United States and Europe.

RISC-V spends 44 cycles on an interrupt, Cortex-M0 only 27
A technical critique of RISC-V’s design, published by engineer Dmitry.GR, breaks down why the open ISA’s interrupt handling is more costly than that of a low-end ARM Cortex-M0 core. The analysis counts cycle by cycle how the lack of automatic register stacking forces developers to write assembly routines before reaching the C code.

AI Detects Hidden Signs of Solar Flares Hours Before They Happen
A new artificial intelligence model identifies hidden signals in solar data that anticipate a flare with hours of lead time. The news, reported by Phys.org, adds to the wave of AI tools applied to space science. An early warning like this could change how satellites, airlines, and power grid operators prepare for space weather.

skitter-creek-bath-salts unlocks PSP, SMM, and microcode on AMD Family 16h
skitter-creek-bath-salts is a research project that uses DRAM scrambling to rewrite address translation on AMD Family 16h CPUs and expose memory reserved for the PSP, SMM, and the microcode. It’s not a remote attack: it requires physical access and specific hardware, but it questions how solid the memory isolation guarantees are that the rest of the industry takes for granted.
