Some DragonFly HAMMER2 / FreeBSD ZFS / Linux EXT4 Benchmarks

Filed under
Linux
BSD

With the recent release of DragonFlyBSD 5.2 one of the prominent changes is HAMMER2 now being considered stable for most use-cases. I've been running some benchmarks of this file-system compared to alternatives on other operating systems and have some FreeBSD / Linux reference points to share.

Complementing my earlier HAMMER vs. HAMMER2 benchmarks, I ran a set of I/O tests on TrueOS and FreeBSD 11.1 as well as Ubuntu and Clear Linux. All tests were done using the same Intel Xeon E3-1280 v5 Skylake system with 256GB Toshiba RD400 NVMe SSD, same default CPU clock frequencies, etc.

Filed under
Linux

Oracle Enterprise Linux 7 Update 5 is now available for download for the x86_64 (64-bit) hardware architecture and brings with it Oracle's Unbreakable Enterprise Kernel (UEK) Release 4 kernel (kernel-uek-4.1.12-112.16.4.el7uek) and a Red Hat Enterprise Linux compatible kernel (kernel-3.10.0-862.el7). Oracle noted that fact that Oracle Enterprise Linux 7.5 remains compatible with apps that have already been certified for the Oracle Linux 7 and Red Hat Enterprise Linux 7.

"Oracle Linux maintains user space compatibility with Red Hat Enterprise Linux (RHEL), which is independent of the kernel version that underlies the operating system. Existing applications in user space will continue to run unmodified on Oracle Linux 7 Update 5 with the UEK Release 4 and no re-certifications are needed for applications already certified with Red Hat Enterprise Linux 7 or Oracle Linux 7," said Avi Miller, Product Management Director, Oracle Linux.

5 Things to understand before switching to Linux – For The Record

Filed under
GNU
Linux

1 – Linux isn’t Windows. There is no magical company to go to,things will behave differently. If you expect a parity experience, you’re going to be disappointed. Software types, source of software or installing a new driver.

2 – Linux does what it’s told to. Something isn’t working? Odds are, it’s just not working as expected it means you need to adjust a configuration or rethink the tools used to interact with Linux. This includes hardware not appearing to work, audio and video.

3 – Linux applications may work differently than legacy applications. MS Word vs LibreOffice, Photoshop vs GIMP, exe installers vs repositories.

4 – Linux offers choice. Different distros, desktop environments and methods of application installation.

Launching Netrunner 18.03 for the Pinebook

Filed under
GNU
Linux

The team over at Netrunner have just announced the launch of Netrunner 18.03 Idolon for the Pinebook. This is the direct result of a year of collaboration between the Netrunner, Pine and KDE Communities in a effort to drive down memory consumption, fix glitches in the graphics stack and enabling accelerated video decode, all of which has resulted in a product that showcases the coming together of the amazing software from KDE and some brilliant hardware engineering from the folks over at Pine.

It’s been quite a journey for my colleagues and I at Blue Systems in putting together this product. We have had to delve into areas where we originally did not have the expertise to fix bugs and constantly push the boundaries of our abilities. This was especially challenging in the ARM world since there are parts of the stack that were proprietary, meaning we cannot debug those parts, leading to many frustrating evenings having been spent on trying to reverse engineer buggy behaviour.

  • Detailing The Idle Loop Ordering Problem & The Power Improvement In Linux 4.17

    Of the many great features/changes for Linux 4.17, one of the most exciting to us is the idle power efficiency and performance-per-Watt improvements on some systems thanks to a rework to the kernel's idle loop handling. Rafael Wysocki and Thomas Ilsche as two of the developers working on this big code change presented on their work today for this CPU idle loop ordering problem and its resolution.

  • Linux 4.17 development underway

    Linus Torvalds has started the development cycle of the Linux 4.17 kernel series, according to a report by Softpedia.

    The first Release Candidate build has been released, and comes two weeks after the launch of Linux 4.16.

    “Public testers can start downloading, compiling, and installing the upcoming Linux 4.17 kernel,” stated the report.

  • Linux Foundation seeks to harmonise open source and standards development

    A year ago The Linux Foundation created its 'Harmonisation 1.0' initiative, focusing on collaboration between projects and with standards bodies. It brought together a set of open source projects, which together form the basis of the modern telecoms systems. Open source creates three values for telcos: speed to services, vendor collaboration, and cost reductions. The LF is also creating a framework between open source and standards communities; for example, this year it announced an agreement with the TM Forum, focused on the APIs that work between the two communities.

  • Broadcom VC5 DRM Driver Might Soon Be On Its Way To The Mainline Linux Kernel

    Eric Anholt believes he is getting quite close to the stage of merging the Broadcom VC5 DRM driver into the mainline Linux kernel tree.

    As part of the VC5 open-source driver stack for supporting the next-gen Broadcom VideoCore 5 graphics hardware, there's been the VC5 Gallium3D driver that is already in mainline Mesa for OpenGL support and the VC5 DRM driver that has been outside of the kernel tree up until now. (There's also been the also out-of-tree experimental work on VC5 Vulkan support via BCMV, etc.)

  • NVIDIA 396.18.02 Vulkan Linux Beta Brings Better Shader Performance

    Last week NVIDIA released their first 396 Linux driver beta that most notably introduces their new "NVVM" Vulkan SPIR-V compiler. Coming out today is a new Vulkan beta update with some continued enhancements.

  • AMDVLK Driver Updated With Latest XGL/PAL Fixes

    AMD kicked off the start of a new week by doing fresh code drops of the PAL and XGL code-bases used to form the AMDVLK open-source Radeon Vulkan Linux driver.

    On the XGL side this latest code drop of around one thousand lines of code reduces the number of malloc/free calls, support for INT64 atomic operations within LLPC (the LLVM Pipeline Compiler), other tweaks to LLPC, more barriers in the render pass clear, adding FMASK shadow table support, and other changes.

  • X.Org 2018 Elections Yield 54% Voter Turnout, Select Four New Board Members

    The 2018 X.Org Board of Directors elections are over with 49 of the 91 X.Org registered members having casted a ballot.

A look at Mixxx in GNU/Linux

Linux

Most people tend to think of DJ's using Macbooks alongside their equipment when picturing a DJ who uses a laptop in today's world, but little do most realize that GNU/Linux systems can hold their own as well.

As a part-time dabbler in electronic music production (read: I mix tunes for my own amusement, and a couple uploaded here and there) I have a few programs that I bounce around from depending on the purpose I need, but generally speaking I don't really muck around a lot with things, and I tend to prefer to just simply mix two songs together live and on the fly, record it, and win.

SUSE: openSUSE Tumbleweed and SUSE in HPC

  • Krita, Linux Kernel, KDEConnect Get Updated in Tumbleweed
    There have been a few openSUSE Tumbleweed snapshots released in the past two weeks that brought some new features and fixes to users. This blog will go over the past two snapshots. The last snapshot, 20180416, had several packages updated. The adobe-sourceserifpro-fonts package updated to version 2.000; with the change, the fonts were refined to make the Semibold and Bold heavier. Both dbus-1 and dbus-1-x11 were updated to 1.12.6, which fixed some regreations introduced in version 1.10.18 and 1.11.0. The gtk-vnc 0.7.2 package deprecated the manual python2 binding, which will be deleted in the next release, in favor of GObject introspection. Notifications that caused a crash were fixed in kdeconnect-kde 1.3.0. The 4.16.2 Linux Kernel made ip_tunnel, ipv6, ip6_gre, ip6_tunnel and vti6 better to validate user provided tunnel names. Due to a build system failure, not all 4.16.2 binaries were built correctly; this will be resolved in the 20180417 snapshot, which will be released shortly. Krita 4.0.1 had multiple fixes from its major version upgrade. The visual diff and merge tool meld 3.19.0 added new features like a new per-pane status bar with selectors for syntax highlighting and text encoding. Python Imaging Library python-Pillow 5.1.0 removed the freetype-2.9.patch and YaST had several packages with a version bump.
