An Easy Way To Build An Ubuntu Kernel With Hopefully Better Scheduler Performance
Since the recent news about the Linux kernel being in worse shape than some people imagine, there's already been some downstream corrective action taking place. Clear Linux is one of the distributions already patching/tweaking their kernel for better scheduler performance but so far we haven't heard anything from the Ubuntu camp. Fortunately, there's been others working on their own solutions.
A Phoronix reader contacted me this week about his build_ubuntu_kernel_wastedcores script. This script makes it easier to spin your own Ubuntu custom kernel and integrates the "wasted cores" patch cited by the earlier research into the poor shape of the Linux kernel scheduler.

Ubuntu 16.04 Released: See what’s new
For those who might not be aware of that fact that Canonical keep the funkiest name for their project. All the official Ubuntu release names are like Ubuntu X.YY where is X is the Year of release Minus 2000 and YY is the Month of release. Since the date of release is not known and cannot be predicted till release, Canonical conventionally names all it release as Adjective + Animal. In Ubuntu 16.04, Xerial is an Adjective and Xerus is an Animal.

A long waited release Ubuntu 16.04 has finally been made available to download with some new & interesting features. Ubuntu 16.04 is a long-term supported release that means once you install Ubuntu 16.04, it's going to provide security updates, bug fixes and applications updates for 5 years with no if and but. Ubuntu and other family members' (Ubuntu Mate, Kubuntu, Lubuntu, Xubuntu etc.) 16.04 version can be downloaded and installed.
For obvious safety reasons, most jurisdictions across the US and the world prohibit someone from driving a car if a “video monitor” is clearly visible from the driver’s seat. Hence why even though Tesla’s 17-in center display could certainly be capable of playing videos, the automaker disabled any video playing capabilities other than the video feed from the rear camera.
It didn’t stop a hacker who recently managed to install Gentoo, a Linux-based operating system, in her car and can now play videos directly from her Model S’ 17-in display.
I am using ‘her’ here because the hacker is staying anonymous but goes by ‘Hemera’, the Greek goddess of daytime.
Ubuntu continued to dominate the headlines today with some reporting the new version being actually available and all the usual accompanying posts. One of the more interesting Ubuntu articles of the day came from Matthew Garrett who said that Snap applications could expose your private data. In other Ubuntu news, Mark Shuttleworth announced the new codename for the next release already. Elsewhere, Gentoo was hacked onto a car computer and Microsoft is hiring Linux developers.
The Fedora Cloud Working Group has decided to retire the 32-bit Cloud images. As of the Fedora 23 release, we will no longer produce the 32-bit images. We will, of course, continue to make 64-bit cloud images available.
Why are we doing this? We’ve been producing 32-bit images for years, and it’s a solved problem, right? Surely it’s as easy as “just keep doing it,” right?
According to the release notes
Thunar is the subject of a few bugs, though they all appear to revolve around similar issues. We have 2 patches applied that, while not completely fixing the issue, do lessen the impact.
I know Thunar used to crash a lot during copy/paste and it looks like the devs haven't repaired it. So, can you say that the newest Xubuntu is stable at all? I don't want to install the second file manager because it won't be integrated well with Xubuntu.submitted by /u/onixfan2137
Ireland’s police force, An Garda Síochána, is tentatively considering using the open source version of SugarCMR for more of its web services. The police force has been using the software for its eVetting project since 2013, after comparing its costs and support options with proprietary alternatives.
Can't see anything obvious in searching here or the magical googles, apologies if this has been asked a bunch...
So, snap is a thing now. Awesome, looks great on the surface etc. Bundling dependencies into the package seems really wise in some ways, but... how does that actually work?
Let me ask by way of example: Developer X includes a dependency of "Package Y" in their snap "Z", a critical vulnerability comes out for Y and they never get around to updating their snap for Z. Am I now left with an insecure package and at the mercy of each developer who uses "Y" as part of their snap, or are snaps smart enough to repackage a new snap each time a dependency updates?submitted by /u/dreadmin
