LLVM project founder Chris Lattner has proposed a new decision making process for the LLVM compiler stack around new sub-project proposals, new social policies, changes to core infrastructure, and other key changes...

Yesterday we noted that the Linux kernel picked up a patch mitigating an Intel Gen9 graphics vulnerability. It didn't sound too bad at first but then seeing Ivy Bridge Gen7 and Haswell Gen7.5 graphics are also affected raised eyebrows especially with that requiring a much larger mitigation. Now in testing the performance impact, the current mitigation patches completely wreck the performance of Ivybridge/Haswell graphics performance.

As we mentioned back in December, a Kubuntu-powered laptop is launching with the blessing of Canonical and the Kubuntu Community Council. That laptop, the Kubuntu Focus, will begin shipping at the beginning of February while the pre-orders opened today as well as the embargo lift. We've been testing out the Kubuntu Focus the last several weeks and it's quite a polished KDE laptop experience for those wanting to enjoy KDE Plasma for a portable computing experience without having to tweak the laptop for optimal efficiency or other constraints.

Coming to Linux last year with the 5.3 kernel was Intel Speed Select Technology support as a Cascade Lake feature for optimizing the per-core performance configurations to favor certain cores at the cost of reducing the performance capacity for other CPU cores. That Intel Speed Select (SST) support for Linux is now being enhanced with core-power controls...

While Canonical no longer develops their Unity 8 stack for Ubuntu, the UBports crew continues advancing Ubuntu Touch mobile as a community project and as part of that they do work on Unity 8 for their devices and desktop support. But if you're hoping to see Unity 8 running nicely on Ubuntu 20.04 LTS, that could be a while...

Git 2.25 is out today with over 500 commits making up this latest feature release...

Last week marked the two year anniversary since the formal public disclosure of the Spectre and Meltdown disclosures. To commemorate that anniversary, I was running some fresh benchmarks of various Intel desktop and server processors with the in-development Ubuntu 20.04 LTS to look at the performance impact today with the default CPU vulnerability mitigations and then again with the mitigations disabled at run-time.

The first development release of Phoronix Test Suite 9.4-Vestby is now available for evaluation...

One of the set of patches for Intel's Linux kernel graphics driver that have been floating around for more than one year is about exposing per-client (process) statistics in how each application is making use of the GPU's render/blitter/video hardware and various insightful statistics related to that. The patches aren't queued for mainline yet but at least a new revision of the work was published...

Wine 5.0 is still going through weekly release candidates but the stable release of Wine 5 is expected to land in the back-half of January. With that imminent release, here is a look at the big changes to find with this annual Wine update...

Here is another long overdue kernel change... For more than a decade there have been patches trying to get SATA/SCSI drive temperature monitoring working nicely within the Linux kernel but none of that work ever made it through for mainlining. That has left various user-space tools to provide the functionality, but in doing so that has required root access and not to mention the need to first install said utilities. Well, with Linux 5.6 in 2020, there is finally a proper drive temperature driver for disks and solid-state drives with temperature sensors...

Making rounds in Q4 of last year was the little known Project Trident open-source operating system switching from its TrueOS/FreeBSD base to in turn moving to Void Linux as a base for their platform. Towards the end of the year they offered some initial images of their reborn OS while now Project Trident based on Void Linux has reached beta...

I refrained from writing about Valve's Steam Survey numbers at the start of January when they were posted for December as the numbers didn't seem up to scratch. But half-way through the month now, the same numbers are up with no edits by Valve, as we've seen in some months when they refine their measurements...

I reported a few days ago GCC was hoping to transition to Git this weekend from their large SVN repository. Going into this weekend I wasn't going to be the least bit surprised if this transition got delayed again given all of the months of delays already, but actually, they went ahead and migrated to Git!..

KDE developers fixed a number of Wayland and KWin bugs this week along with a number of other annoying bugs as well as making several other noteworthy refinements to the growing KDE ecosystem...
