[$] Going boldly into the COSMIC desktop environment

After three years of development, Linux hardware provider System76
has declared
the COSMIC desktop
environment
stable. It shipped COSMIC Epoch 1 as part of the
long-awaited Pop!_OS 24.04 LTS
release on December 11, just in time for Linux enthusiasts to
have something to tinker with over the end-of-year holidays. With the
stable release out the door, it seemed like a good time to check back
in on COSMIC and see how it has evolved since the first alpha. For a first
stable release of a new desktop environment, COSMIC shows a lot of
promise and room to grow.

Asahi Linux 6.18 progress report

The Asahi Linux project has published
its progress report following the release of Linux 6.18. This time
around the project reports progress on many fronts, including
microphone support for M2 Pro/Max MacBooks, work queued for Linux 6.19
to support USB3 via the USB-C ports, and work to improve the Asahi
Linux installation experience. The project is also enabling as
additional System Management Controller (SMC) drivers, which means
that “the myriad voltage, current, temperature and power sensors
controlled by the SMC will be readable using the standard hwmon
interfaces
“.

Intel Xeon 6980P vs. AMD EPYC 9755 128-Core Showdown With The Latest Linux Software For EOY2025

Since receiving the Gigabyte R284-A92-AAL1 a while back as a Xeon 6900 series 2U server platform to replace the failed Intel AvenueCity reference server, I have been getting caught-up in fresh Xeon 6980P Granite Rapids benchmarks with the latest software updates over the past year. I’ve provided fresh looks at the DDR5-6400 vs. MRDIMM-8800 performance, the AMX benefits for AI, SNC3 vs. HEX mode, Latency Optimized Mode, Cache Aware Scheduling, and more with the fresh Linux software stack and this production Gigabyte server platform. One of the areas I have been meaning to re-visit is a fresh head-to-head benchmark battle between 5th Gen AMD EPYC “Turin” and Intel Xeon 6 “Granite Rapids”. In this article is a 128-core showdown between the Xeon 6980P and EPYC 9755 128-core processors with the latest open-source Linux software as of the end of 2025.

[$] The Civil Infrastructure Platform after (nearly) ten years

The Civil Infrastructure Platform
(CIP) first launched in that form in April 2016, so it has a
tenth-anniversary celebration in its near future. At the 2025 Open
Source Summit Japan
, Yoshitake Kobayashi talked about the goals of this
project and where it is headed in the future. Supporting a Linux system
for even one year is a challenging task; maintaining that support for a
decade or more is rather more so, and a changing regulatory environment
complicates the task further.
