Linux 6.19 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just released Linux 6.19 on the Linux Kernel Mailing List (LKML): No big surprises anywhere last week, so 6.19 is out as expected - just as the US prepares to come to a complete standstill later today watching the latest batch of televised commercials. The betting man would expect them all to be AI-generated, but maybe some enterprising company decides to buck the trend? Doubtful, but there's always a slight chance. But for anybody outside the US, maybe taking the newest kernel out for a spin instead is an option? I have more than three dozen pull requests for when the merge window opens tomorrow - thank you to all the early maintainers. And as people have mostly figured out, I'm getting to the point where I'm being confused by large numbers (almost running out of fingers and toes again), so the next kernel is going to

8devices Maca 2 – A ultra-long-range data radio with 80km range for drones and robotics

8devices Maca 2 high-power plug-and-play ultra-long-range wireless data radio targets drones, UAS, robotics, interceptor systems, industrial IoT, and defense-grade communications, where long range, resilience, and scalability are critical. The device features high transmit power of up to 39 dBm (with 36 dBm per RF chain) and a receiver sensitivity of –98 dBm, and is designed for air-to-ground and point-to-point connectivity over distances of up to 80 km. To maintain stable links over extreme distances, the radio supports ultra-narrow channel widths ranging from 1.5 MHz to 19.5 MHz, significantly improving signal-to-noise ratio and resistance to interference and jamming. Additionally, it includes dual Ethernet, USB 2.0, UART, GPIO, and 14–33 V power input. It also supports industrial temperature operation and NDAA/TAA-compliant manufacturing. For unmanned systems, the radio allows users to manage bandwidth asymmetry. It's a feature where a user can allocate 90% of the channel to downstream video data while reserving 10%
