Clear Linux vs. Ubuntu 19.10 Video Encoder Performance On The Core i9 9900K
Often when doing cross-distribution benchmarks, readers often comment on the performance of Clear Linux particularly for video encoding use-cases as surprisingly different from other distributions. Some argue that it's just over the default CPU frequency scaling governor or compiler flag defaults, so here is a look at that with Ubuntu 19.10 daily benchmarked against Clear Linux.
On the same Core i9 9900K system I recently ran some benchmarks looking at Clear Linux vs. Ubuntu 19.10 and then Ubuntu 19.10 with various common tunables to make it more akin to Clear Linux. Ubuntu 19.10 was used due to its recent software components being at similar versions to Intel's rolling-release distribution.

Serge Hallyn: First experience with Ubuntu Touch
For the past few weeks I’ve been using a nexus 4 running ubuntu touch as, mostly, my daily driver. I’ve enjoyed it quite a bit. In part that’s just the awesome size of the nexus 4. In part, it’s the ubuntu touch interface itself. If you haven’t tried it, you really should. (Sailfish ambiances are so much prettier, but ubuntu touch is much nicer to use – the quick switch to switch between two apps, for instance. Would that I could have both.). And in part it’s just the fact that it really feels like – is – a regular ubuntu system.

Ubuntu 19.10 to use LZ4 compression to boot even faster
anonical’s Ubuntu 19.10 “Eoan Ermine” will boot even faster than its predecessor, Ubuntu 19.04 “Disco Dingo” according to Ubuntu’s kernel team.
After extensive testing on a variety of compression options on the Ubuntu installation image, Canonical engineers determined that the LZ4 decompression method provided a most appreciable gain in speed.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
