GNU Guix 1.0.0 released Version 1.0.0 of the GNU Guix package manager has been released. " This 1.0 release is a major milestone for Guix. It represents 7 years
of hard work with more than 40,000 commits by 260 people, 19 releases,
and an equally amazing amount of work on documentation, translation,
artwork, web design, mentoring, outreach, and many other activities that
together have made it a thriving project." See this

[$] The end of the DAX experiment
Since its inception, the DAX mechanism (which provides for direct access to
files stored on persistent memory) has been seen as somewhat experimental
and incomplete. At the 2019 Linux Storage, Filesystem, and
Memory-Management Summit, Dan Williams ran a session where he said that
perhaps the time has come to end that experiment. Some of the
unimplemented DAX features may never actually need to be implemented, and
it might just be possible to declare DAX finished. But first there are a
few more details to take care of. | | 8:00p |
[$] Write-protect for userfaultfd() The userfaultfd()system call allows one process to handle page faults for another — in user space. Its original use case was to support transparent container migration, but other uses have developed over the years. At the 2019 Linux Storage, Filesystem, and Memory-Management Summit, Andrea Arcangeli described a scheme to add write-protection
support to userfaultfd(). After a year of lost time fighting speculative-execution problems, Arcangeli is about ready to move this feature into the mainline. |
