Spring is coming to the northern hemisphere, and one's thoughts naturally
turn to ... being locked up inside the house and not allowed to go
anywhere. That has, in turn, led to an increasing interest in alternative
mechanisms for keeping up with family and coworkers, especially video
conferencing. There are a number of proprietary video-conferencing
services out there; your editor decided to look into what solutions exist
in the free-software realm. It turns out that there are a few; the first
to be looked at is
Jitsi.

Google Open Source has
announced
the 2020 edition of
Season of Docs, a
program to connect open source projects with technical writers to improve
documentation. Open source organizations may apply from
April 14-May 4. Once mentoring organizations and technical
writers are connected, there will be a month long community bonding period,
beginning August 11. Writers will then work with mentors to complete
documentation projects by the December 6 deadline.

Parrot OS is a security and
privacy focused distribution, with tools for cyber security operations.
Parrot 4.8
follows Debian testing and has many updates from the Debian
repositories. Parrot Docker containers allow you to use Parrot tools on
docker-supported operating systems. Since the previous release last
September the Parrot team has put some effort into reorganizing its
internal structure, from the operations and workflow of developers, up to the infrastructure. "After such a huge work, we have finally moved to the new workflow, and Parrot 4.8 is the proof of how hard we wanted such changes to take place in the project and how smooth development and cooperation became after achieving this goal."

The
5.6-rc7 kernel prepatch is out for
testing; this may be the last one before the final release.
"The world around us may be going through strange times, but at least
so far kernel development looks normal."

The
io_uring subsystem has, in the last
year, redefined how asynchronous I/O is done on Linux systems. As this
subsystem grows in both capability and users, though, it starts to run into
limitations in the types of operations that can be expressed. That is
driving a number of changes in how operations are programmed for io_uring.
One example is the mechanisms considered for carrying a file descriptor
between operations that was
covered here in early March. Another has to
do with how I/O buffers are chosen for operations.

The
Linux Mint Debian Edition (LMDE) 4 has been
released. "LMDE is a Linux Mint project which stands for 'Linux Mint Debian Edition'. Its goal is to ensure Linux Mint would be able to continue to deliver the same user experience, and how much work would be involved, if Ubuntu was ever to disappear. LMDE is also one of our development targets, to guarantee the software we develop is compatible outside of Ubuntu.
LMDE aims to be as similar as possible to Linux Mint, but without using Ubuntu. The package base is provided by Debian instead." It is based on Debian 10 ("Buster") with lots of new features, including many improvements from Linux Mint 19.3. More information can be found in the
release notes.

Author Nick Black has written an extensive book on the creation of textual
user interfaces using the notcurses library; it's
available under the Apache
license [PDF]. "Many people asked how such a thing was
useful. My usual response was that numerous devices don’t present a bitmap
interface, that X11 GUIs run remotely over SSH are effectively unusable,
that plenty of machines don’t have a GUI environment installed, that there
are obvious applications for large outdoor displays, and that Sixel isn’t
well-supported across different terminal emulators. It seems impossible in
an age of gigatransistor graphics cards, but the text environment still
presents perceivably less latency than most GUI toolkits."

The kernel's memory-management subsystem goes to great lengths to keep the
pages that are actually in use in memory. But sometimes it gets things
wrong, leading to reduced performance or, in the worst cases, flat-out
thrashing. We may be about to see a significant improvement, though,
thanks to
a
patch set from Joonsoo Kim changing how anonymous pages (those
containing data not backed by files on disk) are managed.
As it turns out, all that had to be done was to make use of some work that
already exists in related parts of the memory-management code.

Here's
a
detailed blog post on how the Qubes distribution is working to isolate
the graphical interface from the rest of the system. "The upcoming
4.1 release changes this protocol to a more flexible form. It will no
longer use direct memory addresses, but an abstract mechanism in which the
qube has to explicitly allow access to a particular memory page. In our
current implementation — under Xen — we use the grant tables mechanism,
which provides a separate memory allocation API and allows working on
grants and not directly on memory pages. Other implementations will also be
possible: whether for another hypervisor (e.g. KVM) or for a completely
different architecture not based on shared memory (e.g. directly sending
frames to another machine)."

The python-ideas mailing list is typically used to discuss new features or
enhancements for the language; ideas that gain traction will get turned
into Python Enhancement Proposals (PEPs) and eventually make their way to
python-dev for wider consideration. Steve Jorgensen recently
started
a discussion of just that sort; he was looking for a way to add
customization to the "pretty-print" module (
pprint)
so that objects could change the way they are displayed. The subsequent
thread went in a few different directions that reflect the nature of the
mailing list—and the idea itself.

Konstantin Ryabitsev
introduces
the "b4" tool for kernel development. Developers and LWN readers will
be familiar with b4 under its previous name:
get-lore-mbox. "On top of that, b4 also
introduces support for cryptographic patch attestation, which makes it
possible to verify that patches (and their metadata) weren't modified in
transit between developers. This is still an experimental feature, but
initial tests have been pretty encouraging." See
this article for early coverage of the
attestation feature.

Drew DeVault
complains
about the complexity of the web and the browsers that work with it.
"The major projects are open source, and usually when an open-source
project misbehaves, we’re able to to fork them to offer an alternative. But
even this is an impossible task where web browsers are concerned. The
number of W3C specifications grows at an average rate of 200 new specs per
year, or about 4 million words, or about one POSIX every 4 to 6 months. How
can a new team possibly keep up with this on top of implementing the
outrageous scope web browsers already have now?"

Legislation recently proposed in the US Senate is ostensibly meant to
combat "child sexual abuse material" (CSAM), but it does not actually do
much to combat that horrible problem. Its target, instead, is the encryption
of user communications, which the legislation—tellingly—never mentions.
The
Eliminating
Abusive and Rampant Neglect of Interactive Technologies Act of 2020,
EARN IT for short, is an attempt to force online service providers
(e.g. Facebook, Google, etc.) to follow a set of "best practices"
determined by a commission, to combat the scourge of CSAM; the composition of
that commission makes it clear that end-to-end encryption will not be one
of those practices, but companies that do not follow the best practices will lose
liability protection for their users' actions. It is, in brief, an
attempt to force providers to either abandon true end-to-end encryption or
face ruinous lawsuits—all without "seeming" to be about encryption at all.
