Gnuplot 6.0 was
released in
December 2023, bringing a host of significant improvements and new
capabilities to the open-source graphing tool. Here we survey the major
new features, including
filled contours in 3D, adaptive plotting resolution, watchpoints, clipping
of surfaces, sector plots for making things like pie charts, and new
syntax for conditionals in gnuplot's scripting language. In addition, there
are
detailed examples of the features described.

David Rowley
looks
deeply into the improvements coming to the query planner in
PostgreSQL 16.
For a long time now, PostgreSQL has been able to remove a LEFT JOIN
where no column from the left joined table was required in the
query and the join could not possibly duplicate any rows.
However, in versions prior to PostgreSQL 16, there was no support
for left join removals on partitioned tables. Why? Because the
proofs that the planner uses to determine if there’s any
possibility any inner-side row could duplicate any outer-side row
were not present for partitioned tables.
The PostgreSQL 16 query planner now allows the LEFT JOIN removal
optimization with partitioned tables.

On February 2, Google announced this year's
"Season of Docs", a program complementing its Summer of Code program
by providing funding to open source projects to hire technical writers to improve
their documentation. Interested projects have until April 2 to apply.
Google Season of Docs provides direct grants to open source projects to improve their documentation and gives professional technical writers an opportunity to gain experience in open source. Together we raise awareness of open source, of docs, and of technical writing.

Stephen Brennan
describes
kernel core dumps in excruciating detail.
Kernel core dumps are complex. They are not simply copies of system
memory; they contain plenty of extra metadata which is critical to
understanding their contents. And like any other type of data, the
design of the file formats can enable lots of flexibility and
power. However, due to the broad variety of tools out there, the
diversity of dump formats is overwhelming, and the lack of
documentation or specifications compounds the problem.

Mitchell Baker has
announced
that she is stepping down from the role of Mozilla CEO, effective
immediately. Laura Chambers will be the new CEO "for the remainder of
the year".
We’re at a critical juncture where public trust in institutions,
governments, and the fabric of the internet has reached
unprecedented lows. There’s a tectonic shift underway as everyone
battles to own the future of AI. It is Mozilla’s opportunity and
imperative to forge a better future. I’m excited about Laura’s
day-to-day involvement and the chance for Mozilla to achieve
more. Our power lies in the collective effort of people
contributing to something better and I’m eager for Mozilla to meet
the needs of this era more fully.

The generation of random (or, at least, unpredictable) numbers is key to
many security technologies. For this reason, the provision of random data
as a CPU feature has drawn a lot of attention over the years. A proper
hardware-based random-number generator can address the problems that make
randomness hard to obtain in some systems, but only if the manufacturer can
be trusted to not have compromised that generator in some way. A recent
discussion has brought to light a different problem, though: what happens
if a hardware random-number generator can be simply driven into exhaustion?

The GNU C Library project
has
been accepted as a CVE Numbering Authority (CNA), meaning that the
project is now in control of the CVE numbers assigned to its code.
As a CNA the glibc security team will be working to improve the
quality and response time of security advisories and mitigations.
Over the coming months, the glibc security team will define the
process for the CNA and establish best practices that can also be
used by the rest of the GNU Toolchain.
See this article for some background on
this change.

At the beginning of November, we
let it be
known that we were looking to hire a writer/editor to augment the LWN
team. In past attempts, we have found it difficult to attract writers who
could produce the kind of content that LWN readers expect. This time
around, as we have said before, was different; we had a number of
candidates who could have filled the bill and were forced to make some
difficult choices.
While "hire them all" was an attractive idea, it was not one that our
budget would support. We did conclude, however, that we could stretch to a
second hire. So we are pleased to announce that the opportunity to bring
Joe Brockmeier on board was too good to pass up — so we didn't. You will
start to see his work return to LWN within the next few days.

Go 1.22, the most recent version of the
Go programming language, has been released. It comes with two language changes to for loops: a
fix for a longstanding "gotcha" with accidentally sharing loop variables between iterations and adding the ability to range over integer values. There are also additions to the standard library, improved performance, and more. See the
release notes for further information.
