Dictionaries are ubiquitous in Python code; they are the data structure of choice for a wide variety of tasks. But dictionaries are mutable, which makes them problematic for sharing data in concurrent code. Python has added various concurrency features to the language over the last decade or so—async, free threading without the global interpreter lock (GIL), and independent subinterpreters—but users must work out their own solution for an immutable dictionary that can be safely shared by concurrent code. There are existing modules that could be used, but a recent proposal, PEP 814 ("Add frozendict built-in type"), looks to bring the feature to the language itself.
Andreas Schneider has announced version 2.0 of the cmocka unit-testing framework for C: This release represents a major modernization effort, bringing cmocka firmly into the "modern" C99 era while maintaining the simplicity and ease of use that users have come to expect. One of the most significant changes in cmocka 2.0 is the migration to C99 standard integer types. The LargestIntegralType typedef has been replaced with intmax_t and uintmax_t from stdint.h, providing better type safety and portability across different platforms. Additionally, we've adopted the bool type where appropriate, making the code more expressive and self-documenting. Using intmax_t and uintmax_t also allows to print better error messages. So you can now find e.g. assert_int_equal and assert_uint_equal. cmocka 2.0 introduces a comprehensive set of type-specific assertion macros, including `assert_uint_equal()`, `assert_float_equal()`, and enhanced pointer assertions. The mocking system has also been significant
The out-of-tree Bcachefs file-system is ready with its reconcile feature, which previously was known as "rebalance_v2", and what lead developer Kent Overstreet calls the biggest feature to this copy-on-write file-system in the last two years...
This week brought the official release of FreeBSD 15.0 as the latest major update to this BSD operating system. In being eager to test out this new FreeBSD release, for this first round of FreeBSD 15.0 benchmarking is seeing how it compares to the former FreeBSD 14.3 release on a Supermicro + AMD EPYC Turin server.

Pardus 25.0 promises a “just install and go” experience for Linux users. We test whether this Turkish distro lives up to that promise. The post Is Pardus 25.0 Turkey’s Perfect Gift to Linux Users? appeared first on FOSS Force.
The "timers/core" pull requests for updating Linux kernel timer-related code doesn't tend to be too interesting each kernel cycle, but this time around for Linux 6.19 it is for addressing a problem HPE discovered on big NUMA servers...
