  • Voice of the Masses: Should the Linux Foundation have community representation?

    According to their own website: “The Linux Foundation protects and promotes the ideals of freedom and generous collaboration established through the development of Linux, and shares these ideals to power any endeavor aiming to make the future a better place in which to live.” This is indeed a noble goal, and to assist it in this endeavor, many of the world’s largest technology companies pay tens and even hundreds of thousands of dollars. All this money is first stored in a Scrooge McDuck style silo before being used to pay the salaries of some kernel developers, passed on to projects improving security in open source, and used to promote Linux in a wide variety of ways.

  • Yosembiance A Smooth and Sleek Theme Based On Ambiance

    Do you like Ambiance theme but also like flat themes? Yosembiance is smoothed and slightly flattened version of Ubuntu default theme Ambiance and it is modified by Brain Sundman, he tried to make this theme more beautiful and he succeeded, the Ubuntu's default theme Ambiance is also beautiful there is no doubt about it. The initial release of this theme was in 2014 and with the passage of time Brain also made this theme available for newer Ubuntu versions. There is blue version too, if you don't want to stick with orange one then you can choose blue for your desktop. I added this theme to PPA for Ubuntu 16.04 Xenial/15.10 Wily/15.04 Vivid/14.04 Trusty, and this theme is not tested on Linux Mint but hopefully it will work just fine, you can give it a shot and let us know in the comment below. You can use Unity Tweak Tool, Gnome-tweak-tool or Ubuntu-Tweak to change themes/icons.

  • All About Folder Sharing on OpenSUSE 42.1

    This is not the Brazilian dance guys. Samba is a free software licensed under the GNU General Public License and a re-implementation of the SMB/CIFS networking protocol which was originally developed by Andrew Tridgell. Samba is used for sharing files & folders between UNIX & Linux like system towards a Windows OS driven PC. Samba allows a non-Windows server to communicate with the same networking protocol as the Windows products and that’s the interesting part of it. Samba was originally developed for UNIX but now a days it can run on Linux, FreeBSD and other UNIX variants.The name Samba comes from SMB (Server Message Block). Samba works on the majority of modern operating systems available today.

  • [Fedora] Marketing – Year in Review

    Fedora experienced a significant amount of growth and development over the last year. With the growth and recent changes, there were new challenges that Fedora and the Marketing team had to face. The Magazine went really well with significant growth concerning the overall traffic (many thanks to Paul, Ryan, Joe, Chris, Justin) and with more infrastructure stability (thanks to Chris again and Patrick). On the other hand, the institutional part of Marketing experienced difficulties in keeping current with the changes that 2015 brought.

Kernel: Slowdown, CephFS, and FS-Cache / CacheFiles

  • How a performance boost in Linux kernel for one family of Intel chips slowed its latest Alder Lake processors

    The mixture of performance and efficiency CPUs in Intel’s 12th-gen Core processors, code-named Alder Lake, hasn’t just been causing problems for some Windows gamers – it almost led to complications for Linux. Phoronix’s Michael Larabel noticed a performance hit in the kernel a fortnight ago – in a work-in-progress release candidate, we should stress – and a fix for the scheduling code landed a little later. It turned out the kernel suffered on Alder Lake chips due to a performance-enhancing tweak for another Intel processor family: the multiple-Atom-core-based Jacobsville. This year, Intel officially canned its Lakefield chips. These consisted of a performance core called Sunny Cove as well as Atom-class efficiency cores dubbed Tremont. Crucially, there are still multi-Tremont-core embedded processors out there, such as Snow Ridge. These are server and infrastructure-oriented components with up to 24 cores. The first proposed cut of kernel 5.16, specifically 5.16-rc1, contained a revision to the scheduler that makes it aware that some clusters of cores share a block of L2 cache – as seen in Snow Ridge and Jacobsville.

  • Testing the Linux Kernel CephFS Client with xfstests

    I do a lot of testing with the kernel cephfs client these days, and have had a number of people ask about how I test it. For now, I’ll gloss over the cluster setup since there are other tutorials for that.

  • Major Rewrite Of Linux's FS-Cache / CacheFiles So It's Smaller & Simpler - Phoronix

    As part of David Howells of Red Hat long-term work on improving the caching code used by network file-systems, he today posted a big patch series rewriting the fscache and cachefiles code as the latest significant step on that adventure. Howells posted a set of 64 patches for rewriting the kernel's fscache and cachefiles code. Linux's fsache is a general purpose cache used by network file-systems while cachefiles is for providing a caching back-end for mounted local file-systems. The Red Hat engineer has been working on this rewrite for more than the past year.

  • The Calculator Charm: Calculatorium Leviosa! | Hackaday

    Have you ever tried waving your hand around like a magic wand and summoning a calculator? We would guess not since you’d probably look a little silly doing so. That is unless you had [Andrei’s] cool gesture-controlled calculator. [Andrei] thought it would be helpful to use a calculator in his research lab without having to take his gloves off and the results are pretty cool. His hardware consists of a PocketBeagle, an OLED, and an MPU6050 inertial measurement unit for capturing his hand motions using an accelerometer and gyroscope. The hardware is pretty straightforward, so the beauty of this project lies in its machine learning implementation.
