Book: Perl 7: A Risk-Benefit Analysis
Dan Book has done a detailed analysis of the Perl 7
transition. "Large amount of CPAN modules will not work in Perl 7; plans for
working around this would either involve every affected CPAN author, which is a
virtual impossibility for the stated 1 year time frame; or the toolchain group,
a loose group of people who each maintain various modules and systems that are
necessary for CPAN to function, who either have not been consulted as of yet or
have not revealed their plans related to the tools they maintain. Going into
this potential problem sufficiently would be longer than this blog post, but
suffice to say that a Perl where highly used CPAN modules don't seamlessly work
is not Perl."

[$] Netflix releases open-source crisis-management tool
Earlier this year, Netflix developed and released a new
Apache-licensed project named Dispatch. It is designed to coordinate the
response to and the resolution of security-related incidents, but the project
aims for more than just that. Rather, it hopes to be valuable for any type of
one-off incident that needs coordination across an organization, such as a
service outage.
LPC town hall #2: the kernel report
The Linux Plumbers Conference has announced the second in a
brief series of "town hall" events leading up to the full (virtual) conference
starting August 24. This one features LWN editor Jonathan Corbet
presenting a version of his "Kernel Report" talk covering the current and future
state of the kernel-development community. This talk is scheduled for
July 16 at 9:00AM US/Mountain time (8:00AM US/Pacific, 3:00PM UTC). Mark
your calendars.
[$] Btrfs at Facebook
The Btrfs filesystem has had a long and sometimes turbulent
history; LWN first wrote about it in 2007. It offers features not found in any
other mainline Linux filesystem, but reliability and performance problems have
prevented its widespread adoption. There is at least one company that is using
Btrfs on a massive scale, though: Facebook. At the 2020 Open Source Summit
North America virtual event, Btrfs developer Josef Bacik described why and how
Facebook has invested deeply in Btrfs and where the remaining challenges
are.
