Free Up Disk Space by Removing Old Snap Versions

Running out of disk space on Ubuntu? Before you start uninstalling applications or clearing caches, you might want to check your snap revisions. I’ve been getting low disk space warnings on a 40GB Ubuntu partition. The usual tips to free space on Ubuntu weren’t enough, so I opened Disk Usage Analyser and found nearly 8GB was eaten up by old snap versions (you can run sudo du -sh /var/lib/snapd too). Not active versions of Snaps I have installed; backups of every snap I have installed. There, idle, in the snapd folder consuming several gigabytes β€œjust in case” I need to […]

DDR5-4800 vs. DDR5-6000 Performance With The AMD Ryzen 7 9850X3D In 300+ Benchmarks

With the incredible market demand around DDR5 memory and significantly elevated pricing on the more premium DDR5 memory modules, as part of the AMD Ryzen 7 9850X3D launch there's been some communication that thanks to 2nd Gen AMD 3D V-Cache, using lower memory speeds like DDR5-4800 can be suitable without much of an impact to the gaming performance. But what about for Linux gaming? And other workloads with the Ryzen 7 9850X3D? Complementing yesterday's Linux review of the Ryzen 7 9850X3D are benchmarks of DDR5-4800 vs. DDR5-6000 performance with Ubuntu Linux and this new 3D V-Cache 8-core / 16-thread desktop processor.

IO_uring Zero-Copy Large Receive Buffer Support To Provide A Nice Performance Win

Slated for introduction in the next kernel cycle (Linux 6.20~7.0) is introducing large receive buffer support for IO_uring's zero-copy receive code path. This large receive buffer support can be very beneficial for those with higher-end networking hardware capable of handling the larger buffers for some significant performance and efficiency wins...

Valve Developer Improves Aging AMD APUs On Linux With VRR, DP/HDMI Audio, HDR & Atomic

Timur KristΓ³f of Valve's Linux graphics team last year addressed remaining issues in the open-source AMDGPU kernel graphics driver so old AMD GCN 1.0 and GCN 1.1 GPUs could transition to using AMDGPU by default rather than the former "Radeon" kernel driver that is largely in maintenance mode for pre-GCN/RDNA GPUs. One caveat though was the GCN 1.1 APU support still having some limitations leading to Kaveri and friends not being able to use the modern AMDGPU DC "Display Core" code. But new patches from Timur take care of those limitations...
