GNOME and Fedora

  • RFC: Integrating rsvg-rs into librsvg

    I have started an RFC to integrate rsvg-rs into librsvg. rsvg-rs is the Rust binding to librsvg. Like the gtk-rs bindings, it gets generated from a pre-built GIR file.

  • 1+ year of Fedora and GNOME hardware enablement

    A year and a couple of months ago, Christian Schaller asked me to pivot a little bit from working full time on Fleet Commander to manage a new team we were building to work on client hardware enablement for Fedora and GNOME with an emphasis on upstream. The idea was to fill the gap in the organization where nobody really owned the problem of bringing up new client hardware features vertically across the stack (from shell down to the kernel), or rather, ensure Fedora and GNOME both work great on modern laptops. Part of that deal was to take over the bootloader and start working closer to customers and hardware manufacturing parnters.

  • Fedora Atomic Workstation: Works on the beach

    My trip is getting really close, so I decided to upgrade my system to rawhide. Wait, what ? That is usually what everybody would tell you not to do. Rawhide has this reputation for frequent breakage, and who knows if my apps will work any given day. Not something you want to deal with while traveling.

Why You Shouldn’t Use Firefox Forks (and Proprietary Opera)

Filed under
Web
  • Why You Shouldn’t Use Firefox Forks Like Waterfox, Pale Moon, or Basilisk

    Mozilla Firefox is an open source project, so anyone can take its code, modify it, and release a new browser. That’s what Waterfox, Pale Moon, and Basilisk are—alternative browsers based on the Firefox code. But we recommend against using any of them.

  • Opera Says Its Next Opera Release Will Have the Fastest Ad Blocker on the Block

    Opera Software promoted today its upcoming Opera 52 web browser to the beta channel claiming that it has the faster ad blocker on the market compared to previous Opera release and Google Chrome.

    One of the key highlights of the Opera 52 release will be the improved performance of the built-in ad blocker as Opera claims to have enhanced the string matching algorithm of the ad blocker to make it open web pages that contain ads much faster than before, and, apparently than other web browsers, such as Chrome.

  • Glxinfo Gets Updated With OpenGL 4.6 Support, More vRAM Reporting

    The glxinfo utility is handy for Linux users in checking on their OpenGL driver in use by their system and related information. But it's not often that glxinfo itself gets updated, except that changed today with the release of mesa-demos-8.4.0 as the package providing this information utility.

    Mesa-demos is the collection of glxinfo, eglinfo, glxgears, and utilities related to Mesa. With the Mesa-demos 8.4.0 it is predominantly glxinfo updates.

  • Intel ANV Getting VK_KHR_16bit_storage Support Wrapped Up

    Igalia's Jose Maria Casanova Crespo sent out a set of patches today for fixes that allow for the enabling of the VK_KHR_16bit_storage extension within Intel's ANV Vulkan driver.

    The patches are here for those interested in 16-bit storage support in Vulkan. This flips on the features for storageBuffer16BitAccess, uniformAndStorageBuffer16BitAccess, storagePushConstant16 and the VK_KHR_16bit_storage extension. This support is present for Intel "Gen 8" Broadwell graphics and newer. Hopefully the work will be landing in Mesa Git soon.

  • SPIR-V Support For Gallium3D's Clover Is Closer To Reality

    It's been a busy past week for open-source GPU compute with Intel opening up their new NEO OpenCL stack, Karol Herbst at Red Hat posting the latest on Nouveau NIR support for SPIR-V compute, and now longtime Nouveau contributor Pierre Moreau has presented his latest for SPIR-V Clover support.

    Pierre has been spending about the past year adding SPIR-V support to Gallium3D's "Clover" OpenCL state tracker. SPIR-V, of course, is the intermediate representation used now by OpenCL and Vulkan.

Security: Updates, Tinder, FUD and KPTI Meltdown Mitigation

Security
  • Security updates for Friday
  • Tinder vulnerability let hackers [sic] take over accounts with just a phone number

    The attack worked by exploiting two separate vulnerabilities: one in Tinder and another in Facebook’s Account Kit system, which Tinder uses to manage logins. The Account Kit vulnerability exposed users’ access tokens (also called an “aks” token), making them accessible through a simple API request with an associated phone number.

  • PSA: Improperly Secured Linux Servers Targeted with Chaos Backdoor [Ed: Drama queen once again (second time in a week almost) compares compromised GNU/Linux boxes to "back doors"]

    Hackers are using SSH brute-force attacks to take over Linux systems secured with weak passwords and are deploying a backdoor named Chaos.

    Attacks with this malware have been spotted since June, last year. They have been recently documented and broken down in a GoSecure report.

  • Another Potential Performance Optimization For KPTI Meltdown Mitigation

    Now that the dust is beginning to settle around the Meltdown and Spectre mitigation techniques on the major operating systems, in the weeks and months ahead we are likely to see more performance optimizations come to help offset the performance penalties incurred by mitigations like kernel page table isolation (KPTI) and Retpolines. This week a new patch series was published that may help with KPTI performance.

  • February 2018 coreboot update now available

    Hey everyone, I’m happy to announce the release of an update to our coreboot images for Librem 13 v2 and Librem 15 v3 machines.

    All new laptops will come pre-loaded with this new update, and everyone else can update their machines using our existing build script which was updated to build the newest image. Some important remarks:

  • Purism Releases Updated Coreboot Images For Their Laptops

    Purism has released updated Coreboot images for their Librem 13 v2 and Librem 15 v3 laptops.

    The updated Coreboot images are now re-based to Coreboot 4.7, Intel FSP 2.0, IOMMU (VT-d) support is now available, TPM support is also enabled, and there are fixed ATA errors for 6Gbps speeds.

  • New Inventory with TPM by Default, Free International Shipping

    In November, we announced the availability of our Trusted Platform Module as a $99 add-on for early adopters, something that would allow us to cover the additional parts & labor costs, as well as test the waters to see how much demand there might be for this feature. We thought there would be “some” interest in that as an option, but we were not sure how much, especially since it was clearly presented as an “early preview” and offered at extra cost.

Ubuntu 18.04 LTS (Bionic Beaver) Daily Builds Now Fuelled by Linux Kernel 4.15

Filed under
Ubuntu

The Ubuntu Kernel team promised at the beginning of the development cycle for Ubuntu 18.04 LTS (Bionic Beaver), Canonical's seventh long-term supported Ubuntu release to receive security and software update for the next five years, that they target the Linux 4.15 kernel series for the operating system.

Linux 4.15 had one of the longest development cycles in the history of kernels for GNU/Linux distributions, due to the numerous patches to mitigate the nasty Meltdown and Spectre security vulnerabilities for 64-bit architectures. It finally arrived at the end of January, so it took a month for Ubuntu Kernel team to implement it.

Canonical Releases Major Kernel Security Update for Ubuntu 14.04 to Fix 26 Flaws

Filed under
Linux

A total of 26 security flaws were fixed in today's kernel update for Ubuntu 14.04 LTS systems and derivatives, including an out-of-bounds write vulnerability in Linux kernel's F2F (Flash-Friendly File System) file system, a use-after-free flaw in Linux kernel's ALSA PCM subsystem, and an integer overflow in Linux kernel's sysfs interface for the QLogic 24xx+ series SCSI driver.

Additionally, the kernel update addresses a use-after-free vulnerability in Linux kernel's SCTP protocol implementation, as well as a race condition in the LEGO USB Infrared Tower driver and a use-after-free vulnerability in the USB serial console driver, both allowing a physically proximate attacker to execute arbitrary code or crash the system with a denial of service attack.

Plasma Mobile Could Give Life to a Mobile Linux Experience

Filed under

Linux

In the past few years, it’s become clear that, outside of powering Android, Linux on mobile devices has been a resounding failure. Canonical came close, even releasing devices running Ubuntu Touch. Unfortunately, the idea of Scopes was doomed before it touched down on its first piece of hardware and subsequently died a silent death.

The next best hope for mobile Linux comes in the form of the Samsung DeX program. With DeX, users will be able to install an app (Linux On Galaxy—not available yet) on their Samsung devices, which would in turn allow them to run a full-blown Linux distribution. The caveat here is that you’ll be running both Android and Linux at the same time—which is not exactly an efficient use of resources. On top of that, most Linux distributions aren’t designed to run on such small form factors. The good news for DeX is that, when you run Linux on Galaxy and dock your Samsung device to DeX, that Linux OS will be running on your connected monitor—so form factor issues need not apply.

The npm Bug

Development
  • ​Show-stopping bug appears in npm Node.js package manager

    Are you a developer who uses npm as the package manager for your JavaScript or Node.js code? If so, do not -- I repeat do not -- upgrade to npm 5.7.0. Nothing good can come of it. As one user reported, "This destroyed 3 production servers after a single deploy!"

    So, what happened here? According to the npm GitHub bug report, "By running sudo npm under a non-root user (root users do not have the same effect), filesystem permissions are being heavily modified. For example, if I run sudo npm --help or sudo npm update -g, both commands cause my filesystem to change ownership of directories such as /etc, /usr, /boot, and other directories needed for running the system. It appears that the ownership is recursively changed to the user currently running npm."

  • Botched npm Update Crashes Linux Systems, Forces Users to Reinstall

    A bug in npm (Node Package Manager), the most widely used JavaScript package manager, will change ownership of crucial Linux system folders, such as /etc, /usr, /boot.

    Changing ownership of these files either crashes the system, various local apps, or prevents the system from booting, according to reports from users who installed npm v5.7.0. —the buggy npm update.

Endless OS Helps Tear Down Linux Wall

Filed under
OS
Reviews

The free version of Endless OS adheres to the free license policy. It includes preinstalled video and audio codecs that are free of patents. That can limit the types of files you can play. Non-included codecs are available for purchase at the Endless OS Store.

If you dislike managing frequent system updates and new release upgrades, you may have a special liking for Endless OS. As long as you have an Internet connection, the OS periodically checks for updates and automatically downloads and applies them in the background. You get a notification to restart.

Although this desktop design should be an ideal environment for touchscreens, Endless OS does not take to touch very well. This is a major feature weakness if you have a touchscreen laptop or desktop monitor.
