  • Maintainer's / Kernel Summit 2019 planning kick-off

    The planning process for the 2019 Linux Kernel and Maintainer's Summits (Lisbon, Portugal, September 9 to 12) has begun. If you have a topic that you would like to see discussed at either event, now is the time to send in a proposal to the ksummit-discuss list; click below for the details.

  • How to securely delete files in Linux with srm

    With the Linux platform, there are a few possible tools for this process, some of which cannot be depended on for deleting such information and some which only reliably work on magnetic drives. So if your servers work with SSDs, you need to make sure to use a tool that's up for the task. One such tool is the Secure-delete Toolkit.

  • CGroup Interactions

    CGroups are under constant development, partly because they form the core of many commercial services these days. An amazing thing about this is that they remain an unfinished project. Isolating and apportioning system elements is an ongoing effort, with many pieces still to do. And because of security concerns, it never may be possible to present a virtual system as a fully independent system. There always may be compromises that have to be made.

    Recently, Andrey Ryabinin tried to fix what he felt was a problem with how CGroups dealt with low-memory situations. In the current kernel, low-memory situations would cause Linux to recuperate memory from all CGroups equally. But instead of being fair, this would penalize any CGroup that used memory efficiently and reward those CGroups that allocated more memory than they needed.

    Andrey's solution to this was to have Linux recuperate unused memory from CGroups that had it, before recuperating any from those that were in heavy use. This would seem to be even less fair than the original behavior, because only certain CGroups would be targeted and not others.

  • Intel Comet Lake Support Appears To Be In Good Shape With Linux 5.2

    Intel "Comet Lake" CPUs look like they will be well supported when running on the in-development Linux 5.2 kernel or later.

    Intel Comet Lake is the yet-to-launch successor to Coffee Lake / Whiskey Lake and, yes, yet another 14nm product and Gen 9 graphics. Comet Lake CPUs are rumored to be launched around the middle of the year and reportedly up to 10 physical cores. The most recent rumor is that Comet Lake CPUs will require a new motherboard/socket, but so far there haven't been any apparent Linux kernel commits confirming that fact.

  • The stable Wine 4.0.2 release is now available

    If you prefer to walk on the calmer side of life, the Wine 4.0.2 release has been made available today. As it's just a "maintenance" release, there's no big new features which are reserved for the current 4.xx series currently at 4.14 released on August 17th. With that in mind they noted 66 bugs being marked as solved. These bugs include issues with Worms 2, Warframe, Rogue Squadron 3D, Settlers III, Mass Effect, F.E.A.R. 2: Project Origin, The Sims and plenty more.

28 facts about Linux for its 28th birthday

Nearly three decades ago, Linus Torvalds sent the email announcing Linux, a free operating system that was "just a hobby" and not "big and professional like GNU." It's fair to say that Linux has had an enormous influence on technology and the world in general in the 28 years since Torvalds announced it. Most people already know the "origin story" of Linux, though. Here's 28 things about Linux (the kernel and larger ecosystem) you may not already know. 1 - Linux isn't very useful alone, so folks took to creating Linux distributions to bundle user software with it, make it usable and easier to install. The first Linux distribution was Softlanding Linux System (SLS), first released in 1992 and using the .96p4 Linux kernel. You could buy it on 5.25" or 3.5" floppies, or CD-ROM if you were high-tech. If you wanted a GUI, you needed at least 8MB of RAM. 2 - SLS didn't last, but it influenced Slackware Linux, which was first released in 1993 and is still under development today. Slackware is the oldest surviving Linux distribution and celebrated its 26th birthday on July 17th this year. 3 - Linux has the largest install base of any general purpose operating system. It powers everything from all 500 of the Top 500 Supercomputers to Android phones, Chomebooks, and all manner of embedded devices and things like the Kindle eBook readers and smart televisions.

Quick Guide to The Awesome GNOME Disk Utility

GNOME Disk Utility is an awesome tool to maintain hard disk drives that shipped with Ubuntu. It's called simply "Disks" on start menu on 19.04, anyway. It's able to format hard disks and USB sticks, create and remove partitions, rename partitions, and check disk health. Not only that, it also features writing ISO into disk and vice versa, create ISO image of a disk. This tutorial explains in brief how to use it for 8 purposes. Let's go! Read more
