Widespread power outage in Spain and Portugal
All of Spain is without energy. All systems have shut down immediately and are not coming back. Apparently the same has happened in Portugal.
Show HN: I built a hardware processor that runs Python
Hi everyone,
I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution.<p>I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz).<p>The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.
I independently developed the full stack — toolchain (compiler, linker, codegen), and hardware — to validate the core idea. Full technical details will be presented at PyCon 2025.<p>Demo and explanation here: <a href="https://runpyxl.com/gpio" rel="nofollow">https://runpyxl.com/gpio</a>

Show HN: My self-written hobby OS is finally running on my vintage IBM ThinkPad
Finally got my hobby OS up and running on real hardware. I love the old IBM thinkpads, so thought it was the perfect machine to get it working on. Been working on it for quite some time now, but this has been a big milestone!
