Python's support for multithreaded programs has improved considerably over the last few years with the advent of the "free-threaded" version of the language . But testing multithreaded programs is notoriously difficult, because the underlying host system determines the thread-execution ordering, which adds an element of non-determinism. At PyCon US, Larry Hastings gave a talk ( YouTube video ) about his blanket project, which is meant to provide mechanisms for deterministic testing of multithrea…

Tiered-memory systems are built with multiple types of memory, each of which has different performance characteristics. In addition to the usual DRAM, a tiered system might also provide faster high-bandwidth memory or slower CXL memory. On these systems, the placement of memory allocations has a significant effect on the performance that a workload will obtain. While work on tiered-memory improvements has been ongoing for years, it feels like the pace has slowed a bit recently. Even so, there ar…

When a laptop is asleep, its memory is not unreadable. The right tooling can attach to the computer's memory bus and read out its contents, and cold-boot attacks can theoretically read values from memory for a short time after the computer loses power. That is really an unavoidable fact about the hardware, but some users would still like to ensure that, even if this happens, their long-term encryption keys, such as the key for full-disk encryption, remain unreadable.
