At the top-end of Intel's current Alder Lake line-up is the Core i9 12900K while at the opposite end is the Celeron G6900... The Celeron G6900 is a dual-core Alder Lake processor with a suggested customer price of $42~52 USD (though for the limited quantities available, I ended up paying $69). Curiosity got the best of me for seeing how well this lowest-end Alder Lake part performs under Ubuntu Linux.

In addition to Mesa 22.0 landing Vulkan 1.3 support today with the Radeon RADV and Intel ANV Vulkan drivers, Mesa today also received initial support for next-gen Raptor Lake S processors.
It's crazy to think that in a few days it will already be six years since the debut of Vulkan 1.0, but here we are. The Khronos Group is continuing on their two year major update regiment for Vulkan and today debuting Vulkan 1.3 with more extensions moved to core as well as introducing a new "profiles" concept.

Git 2.35 is out today as the newest update to this widely-used, open-source distributed version control system.
After being an Epic Games exclusive for its first year, HITMAN III launched on Steam last week. While there isn't a native Linux port for HITMAN 3, it does run wonderful under Steam Play with Proton for enjoying this Windows game on Linux complete with Vulkan API rendering. Here are some initial benchmarks of HITMAN 3 on Linux with NVIDIA GeForce and AMD Radeon graphics cards.
The first alpha release of the huge Godot 4.0 is now available! Godot 4.0 has been shaping up to be a massive update for this open-source game engine.

Thanks to hiring more Linux developers and preparing to ramp up for next-generation hardware support, the in-development Linux 5.17 kernel is going to be another exciting step forward for AMD Linux customers.
Among the many new features in Linux 5.17 are several notable network optimizations. Optimizing network performance is a never-ending game and already for a future kernel are a new set of UDP/IPv6 optimizations being worked on.
It's just with the in-development Linux 5.17 kernel that the "asus_wmi_ec_sensors" is making its debut for greatly expanded sensor support for modern ASUS desktop motherboards. However, there is already a new driver that has been in development that ultimately aims to be superior to this still-new driver.
The Linux Vendor Firmware Service (LVFS) with Fwupd for firmware updating on Linux could soon be making it easier to transition older, end-of-life devices off official firmware packages and onto the likes of open-source Coreboot for capable aging PC hardware. This not only would make the system run on more free software but would extend the life of the hardware with firmware updates where the vendor has ceased their support.
Following GCC, the LLVM Clang C/C++ compiler front-end is now defaulting to using the DWARFv5 debugging data format.
This morning marked the release of Linux 5.17-rc1 that officially ends the merge window for this next stable kernel series. Linux 5.17 won't see its stable debut until around the end of March but there is a lot to get excited about for this open-source kernel in 2022.
For those interested in compilers, Mold as the "Modern Linker" is one of the interesting projects to watch in 2022.

SiFive's HiFive Unmatched is the best, readily available RISC-V developer board at the moment with enough horsepower for modest development/porting work and continues seeing improvements with the mainline Linux kernel. But availability on HiFive Unmatched is beginning to dry up and SiFive isn't planning on any further production runs as it begins focusing on the board's successor.
