Posted on by

The Software Freedom Conservancy
(SFC) has announced
the availability of videos from the
first-ever Free and Open Source Yearly
(FOSSY) conference, which was held in July in Portland, Oregon in the US.

During the four days of the conference, there were a wide variety of talks
from speakers with a range of experience and backgrounds, and amazing
community focused discussions. Featuring wide ranging topics such as a panel
discussion about software coops, what
is life like without a smartphone (where the picture on the right is
from), and thinking
about FOSS from a systems theory perspective. Our track organizers
brought together communities from all over, and led by example choosing
speakers, topics and setting up panels for important conversations. There
is definitely a talk that will interest you, whether you are interested
in nonprofit
board structure, an
introduction to Reproducible
Builds or maybe you are looking to have more nature
adventures with free software.

[$] Why glibc's fstat() is slow

Posted on by

The fstat()
system call retrieves some of the metadata — owner, size, protections,
timestamps, and so on — associated with an open file descriptor. One might
not think of it as a performance-critical system call, but there are
workloads that make a lot of fstat() calls; it is not something
that should be slowed unnecessarily. As it turns out, though, the GNU C
Library (glibc) has been doing exactly that, but a fix is in the works.
