Longtime PyPy developer Antonio Cuni has a lengthy blog post that describes his talk at the recently completed 2025 CPython Core Dev Sprint, held at Arm in Cambridge, UK. The talk, entitled 'Tracing JIT and real world Python — aka: what we can learn from PyPy' was meant to ...
The file_operations structure in the kernel is a set of function pointers implementing, as the name would suggest, operations on files. A subsystem that manages objects which can be represented by a file descriptor will provide a file_operations structure providing...

Asynchronous Rust code has what Rain Paharia calls a 'universal cancellation protocol', meaning that any asynchronous code can be interrupted in the same way. They claim that this is both a useful feature when used deliberately, and a source of errors when done by accident....
The Capability Hardware Enhanced RISC Instructions (CHERI) project is a rethinking of computer architecture in order to improve system security. Carl Shaw gave a presentation at Linux Security Summit Europe (LSS EU) about CHERI and the efforts to get Linux running on it. He...
