Attitudinal and modality alterations beget satisfaction that's made to last

The Racket programming language project has released Racket version 9.0. Racket is a descendant of Scheme, so it is part of the Lisp family of languages. The headline feature in the release is parallel threads, which adds to the concurrency tools in the language: "While Racket has had green threads for some time, and supports parallelism via futures and places, we feel parallel threads is a major addition." Other new features include the black-box wrapper to prevent the compiler from optimizing calculations away, the decompile-linklet function to map linklets back to an s-expression, the addition of Weibull distributions to the math library, and more.

The Oracle blog has a lengthy article on enhancements to GCC to help detect overflows of flexible array members (FAMs) in C programs.

We describe here two new GNU extensions which specify size information for FAMs. These are a new attribute, "counted_by" and a new builtin function, "__builtin_counted_by_ref". Both extensions can be used in GNU C applications to specify size information for FAMs, improving the buffer overflow detection for FAMs in general.

This work has been covered on LWN as well.

The call for candidates for the 2025 election for the Linux Foundation Technical Advisory Board has been posted.

The TAB exists to provide advice from the kernel community to the Linux Foundation and holds a seat on the LF's board of directors; it also serves to facilitate interactions both within the community and with outside entities. Over the last year, the TAB has overseen the organization of the Linux Plumbers Conference, advised on the setup of the kernel CVE numbering authority, worked behind the scenes to help resolve a number of contentious community discussions, worked with the Linux Foundation on community conference planning, and more.

Nominations close on December 13.

Slo-Tech - Francoski sodnik Nicolas Guillou, ki je na Mednarodnem kazenskem sodišču skupaj s tremi tožilci in še petimi sodniki, med katerimi je tudi slovenska sodnica Beti Hohler, od letošnjega poletja na ameriškem seznamu posameznikov, za katere so uvedli sankcije, se je razgovoril o praktičnih posledicah. Za Le Monde je opisal posledice, ki so po njegovih besedah zlasti očitne v digitalnem svetu. Sankcije so namreč zavezujoče za vsa ameriška podjetja, ki imajo v lasti večino tehnološke in digitalne infrastrukture, pogosto pa sankcije implementirajo tudi evropska podjetja, ki poslujejo z ZDA.

Now though as we get ready to roll into 2026, Google engineers are looking at bringing back JPEG-XL support to the Chrome web browser...
