It’s exactly what the name implies: a clang-based compiler that
outputs code that runs on Vulkan.
Vcc can be thought of as a GLSL and HLSL competitor, but the true
intent of this project is to retire the concept of shading
languages entirely. Unlike existing shading languages, Vcc makes a
honest attempt to bring the entire C/C++ language family to Vulkan,
which means implementing a number of previously unseen features in
Vulkan shaders
OpenWrt developer John Crispin says:
“In 2024 the OpenWrt project turns 20 years! Let’s celebrate this
anniversary by launching our own first and fully upstream supported
hardware design.” The rest of the message describes the proposed
OpenWrt-native network-routing system, based Banana Pi boards; the project is
being organized through the Software Freedom Conservancy. (Thanks to Dave
Täht).
Thorsten Leemhuis writes
about his plans for improving the kernel’s regression handling in the
coming year.
Top-priority will be “make regzbot more useful for kernel subsystem
maintainers” from now on. My tracking efforts of course will
continue, but everything except regressions in the current and the
previous mainline cycle might not see much attention from my
side. This refocusing also means that I won’t work much on
resolving some ambiguities around “how regressions are supposed to
be handled” which lead to tension quite a few times. But all that
should be for the best in the long term.
Copy-and-patch was selected because the compilation from bytecodes
to machine code is done as a set of “templates” that are then
stitched together and patched at runtime with the correct
values. This means that your average Python user isn’t running this
complex JIT compiler architecture inside their Python
runtime. Python writing it’s own IL and JIT would also be
unreasonable since so many are available off-the-shelf like LLVMs
and ryuJIT. But a full-JIT would require those being bundled with
Python and all the added overheads. A copy-and-patch JIT only
requires the LLVM JIT tools be installed on the machine where
CPython is compiled from source, and for most people that means the
machines of the CI that builds and packages CPython for python.org.
Version 4.5
(“Resilience”) of the Solus distribution has been released. “This
release brings updated applications and kernels, refreshed software stacks,
a new installer, and a new ISO edition featuring the XFCE desktop
environment.”
Security updates have been issued by Debian (squid), Fedora (podman), Mageia (dropbear), SUSE (eclipse-jgit, jsch, gcc13, helm3, opusfile, qt6-base, thunderbird, and wireshark), and Ubuntu (clamav, libclamunrar, and qemu).
The 6.7 kernel was released
on January 7 after a ten-week development cycle. This was, as it
turns out, the busiest cycle ever with regard to the number of changesets
merged. The time has come for our usual look at where all those changesets
came from, with a side trip into how long kernel developers tend to stick
around.
End result: 6.7 is (in number of commits: over 17k non-merge
commits, with 1k+ merges) one of the largest kernel releases we’ve
ever had, but the extra rc8 week was purely due to timing with the
holidays, not about any difficulties with the larger release.
Kernel developers often go out of their way to reduce the memory used by
the kernel itself; that memory is not available for the workloads that
people are actually interested in running on their systems. Lower memory
usage also tends to lead to better performance overall. But there are
times when the expenditure of some extra memory can make the system faster.
The replication of the kernel’s text (executable code) and read-only data
across a NUMA system may be a case in point; patch sets have been posted
adding that capability to two architectures.
Wirth is well-remembered for his pioneering work in programming
languages and algorithms. For these achievements, he received the
ACM Turing Award in 1984, inducted as a Fellow of the ACM in 1994,
and a Fellow of the Computer History Museum in 2004.
They include, among many, being chief designer for the programming
languages Euler (1965), PL360 (1966), ALGOL W (1968), Pascal
(1970), Modula (1975), Modula-2 (1978), Oberon (1987), Oberon-2
(1991), and Oberon-07 (2007).
Version 9.1 of the
Vim editor has been released. “This release is dedicated to Bram
Moolenaar, Vims lead developer for more than 30 years, who passed away half
a year ago. The Vim project wouldn’t exist without his work“. Changes
include new support for classes and objects in the scripting language,
smooth scrolling support, an EditorConfig plugin, and more.
Security updates have been issued by Debian (kernel), Fedora (slurm), Oracle (kernel and postgresql:15), Red Hat (firefox, gstreamer1-plugins-bad-free, thunderbird, tigervnc, and xorg-x11-server), SUSE (polkit, postfix, putty, w3m, and webkit2gtk3), and Ubuntu (nodejs).
The calendar has flipped over into 2024 — another year has begun. Here at
LWN, we do not have a better idea of what this year will bring than anybody
else does, but that doesn’t keep us from going out on a shaky limb and
making predictions anyway. Here, for the curious, are a few things that we
think may be in store for 2024.
Security updates have been issued by Red Hat (firefox and thunderbird), SUSE (gstreamer-plugins-bad, libssh2_org, and webkit2gtk3), and Ubuntu (firefox and thunderbird).
One might not think that much could be said about a simple macro defining a
constant integer value. But the kernel is special, it seems. A change to
the definition of MAX_ORDER has had a number of follow-on effects,
and the task of cleaning up after this change is not done yet. So perhaps
a look at MAX_ORDER is in order.
So as expected, pretty much nothing happened over the holiday week.
We’ve got literally just 45 files changed, and almost a third of
those files aren’t even kernel code (ie things like selftests,
scripting, Kconfig and maintainer file updates). And some of the
rest is prep-work and cleanups for future (real) changes.
But we do have a couple of real fixes in there, and I suspect we’ll
get a few more next week as people come back from their
food-induced torpor.
Version 6.0 of the Gnuplot plotting system
has been released.
Gnuplot has been supported and under active development since 1986.
This is the first new major version of gnuplot since the release of
version 5 in January 2015. It introduces extensions to the gnuplot
command language, an expanded collection of special and
complex-valued functions, additional 2D and 3D plotting styles, and
support for new output protocols.
Gentoo Linux is the prototypical source-based distribution, but there is
now a
binary installation option available as well.
To speed up working with slow hardware and for overall convenience,
we’re now also offering binary packages for download and direct
installation! For most architectures, this is limited to the core
system and weekly updates – not so for amd64 and arm64
however. There we’ve got a stunning >20 GByte of packages on our
mirrors, from LibreOffice to KDE Plasma and from Gnome to Docker.
Version
1.75.0 of the Rust language has been released. Notable changes include
“async
fn and -> impl Trait in traits“, a pointer byte-offset
API, some compiler performance improvements, and a number of stabilized APIs.
