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

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 t

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 use
Emmanuele Bassi kicked off a project to improve GNOME's technical governance with a presentation about his ideas (video) at GUADEC 2025. His nudging has led the project to, slowly, work on creating more formal structures for technical governance. It is adopting a teams structure and looking toward creating a steering c

The online publication industry, as a whole, is struggling, with challenges coming from multiple directions. Thanks to the support of all of you, our readers, LWN would appear to be doing better than most. But the world has changed around us and, in particular, prices have changed considerably. By now, you probably kno
In 2024 the Python 3.13 release added an experimental just-in-time (JIT) compiler to optimize the way that CPython executes Python code. Since then, work has proceeded on the JIT, albeit perhaps less formally than some might like. In June, Python's steering council (SC) put out an announcement that no new development o
Version 155 of the Firefox web browser has been released.
