[$] A FUSE implementation for famfs

LWN
The famfs filesystem is meant to provide a shared-memory filesystem for large data sets that are accessed for computations by multiple systems. It was developed by John Groves, who led a combined filesystem and memory-management session at the 2025 Linux Storage, Filesystem, Memory Management, and BPF Summit (LSFMM+BPF) to discuss it. The session was a follow-up to the famfs session at last year's summit, but it was also meant to discuss whether the kernel's direct-access (DAX) mechanism, which is used by famfs, could be replaced in the filesystem by using other kernel features.

Scientists find ‘mutant’ gene behind foul-smelling species of wild ginger

Small genetic changes in enzyme that prevents bad breath in humans lead to sulphurous scent in some asarum

With a smell of rotting flesh the flowers of certain species of wild ginger are unlikely to be used in a wedding bouquet – although they are irresistible to carrion-loving flies. Now researchers say they have worked out how the sulphurous scent is produced.

Scientists say the odour is down to small changes in an enzyme that prevents bad breath in humans.

Lack of rain and floods both threaten crops. Ministers should heed the experts’ warnings

It is so ingrained in British culture to celebrate sunshine that unless you are a farmer or gardener, it is unusual to complain about the lack of rain. But alarms are being sounded by environmentalists and farmers after a very dry spring followed a winter during which parts of the country, including Northern Ireland, had only 70% of average rainfall.
