  • University of California Loses Access to New Content in Elsevier Journals

    In a statement released Wednesday, UC’s Academic Council encouraged those at the university who might require access to Elsevier’s content to use alternative access methods, such as online repositories where authors deposit free-to-read copies of their papers, and to “refrain from any new independent subscriptions to Elsevier journals.”

    Over the last few months, Elsevier has established nationwide licensing agreements in Norway and Poland, and is close to making such a deal in Hungary. However, it remains in a stalemate in negotiations with consortia of libraries and research institutions in Germany and Sweden. Those groups have also cancelled their subscriptions with the publisher.

Security Leftovers

tuxmachines.org - Sob, 07/13/2019 - 04:57
  • Adjusting the Scope of our Security Vulnerability Disclosure Program

    At EFF we put security and privacy first. That's why over three years ago we launched EFF's Security Vulnerability Disclosure Program. The Disclosure Program is a set of guidelines on how security researchers can tell EFF about bugs in the software we develop, like HTTPS Everywhere or Certbot. When we launched the program, it was a bit of an experiment. After all, as a lean, member-driven nonprofit, we can't give out the tremendous cash rewards that large corporations can provide for zero days. Instead, all we can offer security researchers in return for their hard work is recognition on our EFF Security Hall of Fame page and other non-cash rewards like EFF gear or complimentary EFF memberships.

    Despite the limited rewards, the program has been a tremendous success. As of June 1, 2019, we've had over seventy different security researchers report valid security vulnerabilities to us, as you can see on our Security Hall of Fame page.

Software: GNU Rush, Gis Weather, GNOME’s Weather App, Fork Awesome Sprites for Beast

tuxmachines.org - Sob, 07/13/2019 - 04:55
  • GNU Rush Version 2,1

    Version 2.1 is available for download from GNU and Puszcza archives.
    This version fixes several minor bugs that appeared in previous release 2.0.

  • Customizable Weather Widget ‘Gis Weather’ 0.8.4 Released

    Gis Weather is an open-source desktop weather widget and indicator applet with highly customizable user interface.

  • A Brighter Future is Forecast for GNOME’s Weather App

    A wave of usability improvements are on the horizon for the humble GNOME Weather app.

    The current version of the meteorological must-have might have made my list of the best weather apps for Ubuntu and Linux Mint, but I quipped “aspects of its layout bug me”.

    And it seems I’m not alone.

    [...]

    Horizontal pagination seems like a logical introduction, as does separating hourly forecasts from the 10 day forecast.

    Relaying “current conditions” remains prominent in the redesign, but not at the expense of the overall layout.

    And while I like that the proposed redesign mentions the yr.no weather service that’s used as the backend, I especially like that the client as a whole makes better use of the data that this free service provides.

  • Fork Awesome Sprites for Beast

    The Font Awesome 5 package has some other nice features though, since it’s now based on an SVG icon set, it ships 3 large sprite files that can be used to address individual icons via anchors. For Beast, I decided to stick with the Font Awesome 4 look for now, but since there are good reasons not to use icon fonts and I had the infrastructure for using sprite icons already in place, I looked into ways to generate an SVG sprite file for Font Awesome 4.

    Around February 2018, Julien Deswaef and a few others decided to fork the Font Awesome 4 project as Fork-Awesome. Since then, Fork-Awesome has incorporated new icons and also generated an SVG icon set. Since it is forked from Font Awesome, it has all the Font Awesome 4 icons and can be used as a drop in replacement.

Kernel: F2FS and Compressed Firmware Files

tuxmachines.org - Sob, 07/13/2019 - 04:44
  • F2FS Gains Native SWAP File Support, Other Improvements

    F2FS remains a very interesting file-system and has seen particularly good adoption on newer Android devices while it continues to shine as well for laptop and desktop SSD storage. With Linux 5.3 there is finally native SWAP file support for F2FS that can make use of direct I/O for better swapping performance. F2FS is also getting the ability to pre-allocate physical blocks in a pinned file to avoid fragmentation in append-only workloads, more sanity checks, and a variety of bug fixes.

  • Linux 5.3 Picks Up Support For Compressed Firmware Files - Measurable Storage Savings

    SUSE's Takashi Iwai has been working on support for loading compressed firmware files and with the Linux 5.3 driver core patches there is this support. On his own system, he started out with /lib/firmware occupying over 400MB of the disk. When making use of XZ compression, this dropped to around 130MB in total. Thus easily being able to shave off several hundred megabytes from the disk due to all these firmware blobs is an easy win.

    The firmware files remain compressed on disk while at firmware loading time into the kernel the decompression is done. Only XZ compression is currently supported. When the CONFIG_FW_LOADER_COMPRESS option is enabled, the kernel will first try to load a firmware file of the original name but otherwise falls back trying to load any file with the same name appended by the .xz extension.

Linux May Gain Protection Against Hyper-Threading Attacks

tuxmachines.org - Sob, 07/13/2019 - 04:41

Oracle security researchers have been working on security feature for Linux kernels that could protect Linux-based systems against attacks that affect Intel’s Hyper-Threading (HT) feature. Multiple side-channel threats the feature's vulnerable against, including L1TF/Foreshadow and the MDS attacks, have been revealed over the past few months.

The Oracle developers didn't specify whether or not the recent MDS attacks against Intel’s HT would also be mitigated through its Kernel Address Space Isolation (KASI), only that it will protect against L1TF/Foreshadow. Other side-channel attacks seem to be up for debate, as any extra isolation being introduced into the kernel could potentially impact the performance of Linux systems.

AMD Defects Impact Linux

tuxmachines.org - Sob, 07/13/2019 - 04:37
  • AMD Releases BIOS Fix To Motherboard Partners For Booting Newer Linux Distributions

    AMD has just alerted us that they have released a BIOS fix to their motherboard partners that takes care of the issue around booting newer Linux distributions on the new Zen 2 processors.

    Earlier this week I mentioned AMD would be working on a BIOS fix to address the fundamental problem with booting newer systemd-using Linux distributions on their new Ryzen 3000 series processors. However, I hadn't expected the fix to make it to motherboard vendors in less than one week!

  • AMD: Patch On The Way For Ryzen 3000 Customers Affected By 'Destiny 2' And Linux Boot Problems

    AMD says it was able to root cause and resolve both issues fairly quickly in its BIOS code with a patch, and the company expects motherboard vendors to distribute the patch (potentially in beta BIOS form) by next week.

    Earlier this week a growing number of complaints amassed from Windows gamers concerning the inability to launch Activision's Destiny 2 with various Ryzen 3000 CPUs. On the Linux side of the fence, a fairly critical bug emerged that straight up prevented a system from booting with 5.0 or newer Linux kernels.

    It's nice to have these both addressed and resolved within the first week of launch, and hopefully the motherboard vendors will act quickly to seed this patch to their users. Keep an eye on those BIOS updates!

  • g_test_summary and g_get_console_charset in GLib 2.61.2

    Another short post about new APIs, this time from the upcoming 2.61.2 release. This time it’s two unrelated new APIs, which I’m covering together because they’re fairly short.

    g_test_summary() is a new API along the same lines as the existing g_test_bug() function. It’s to be called from within a unit test to provide a summary of the test to the test harness. In contrast, g_test_bug() provides a bug reference for the unit test. In this fashion, the two can be used to provide documentation within the test code of what the test is testing, how it goes about testing it, and which bug it’s checking for regressions in. The summary passed to g_test_summary() might be printed out as a comment in the test logs.

  • GNOME's Mutter Picks Up Another Optimization For Helping DisplayLink-Type Hardware

    Collabora's Pekka Paalanen landed another optimization this week into GNOME's Mutter for further enhancing the performance of using DisplayLink hardware and similar secondary GPUs under this Linux desktop.

    Over the past few cycles we've seen a lot of improvements made for bettering the performance of DisplayLink USB graphics connected displays under the GNOME desktop environment. While the experience has already improved a lot, for GNOME 3.34 due out in September will be more optimizations.
