Maynard: A Lightweight Wayland Desktop

Filed under
Graphics/Benchmarks

Collabora has been doing a lot of contract work for the Raspberry Pi Foundation over the past year, including porting Wayland to work well on this low-end, low-cost ARM single-board computer. Developers and users have been after a lightweight desktop to use on the Wayland-powered Raspberry Pi but there hasn't been any yet with GNOME Shell and other Wayland-compatible desktops being too heavy (I guess they don't yet count Enlightenment's Wayland compositor or wasn't ready for their time-frame).

Trying Out Radeon R9 290 Graphics On Open-Source

Filed under
Graphics/Benchmarks
OSS

While the Radeon R9 290 has been out more than a half-year, the open-source support is still poor. In fact, when running the latest open-source code there still isn't hardware acceleration by default, and with distributions like Ubuntu 14.04 LTS there's only mode-setting support without any 2D/3D hardware acceleration. In my most recent R9 290 open-source testing, I installed Ubuntu 14.04 x86_64, then installed the Linux 3.14 kernel (and later, Linux 3.15 Git), followed by using the Oibaf PPA for Mesa 10.2-devel and xf86-video-ati Git.

Early Linux 3.15 Benchmarks Of Intel Core i7 + Radeon

Filed under
Graphics/Benchmarks
Linux

While a lot of exciting changes have been introduced, for the test system I used for this initial benchmarking (an Intel Core i7 4770K "Haswell" with AMD Radeon graphics), the results weren't too interesting thus resulting just in this brief one-page article. In this initial benchmarking on the same hardware I compared the Linux performance of the 3.12, 3.13, 3.14, and 3.15-rc1 kernels for representing the latest-generation Intel CPU paired with a Radeon R9 270X graphics card on its open-source driver.

The Results Of Optimizing Radeon's VRAM Behavior

Filed under
Graphics/Benchmarks
Hardware

For those wishing to test out the new Radeon code, Lauri's repositories for this work are this kernel repository and this Mesa repository. He said in an email this morning to me, "The code won't be changing beyond cleanups, there might be small edits to the thesis draft. As the main target was VRAM pressure, it will be pointless to test ioq3 games on 2 GB VRAM, for example - they will show no difference, as they fit completely into VRAM. You can use the radeon.vramlimit=256 kernel parameter to limit VRAM for testing different amounts. The kernel is fully backwards compatible with old mesa, so you should be able to compare just by changing mesa and the vram limit. I should note that there's a big ioq3 regression currently in mesa git[3], so if your comparison mesa is too far back, it could seem like it was caused by my work, when it's in reality in master too."

NVIDIA GeForce GTX 750 Maxwell GPUs Light Up On Linux 3.15

Filed under
Graphics/Benchmarks

For any early GTX 750 owners, before getting too excited, the support is very preliminary. For the GTX 750 and GTX 750 Ti graphics cards I tested them today on Ubuntu 14.04 LTS x86_64 doing a clean install and then using the latest daily Linux 3.15 kernel package from the Ubuntu mainline kernel archive. With both graphics cards, the system booted up fine on Linux 3.15 with the Nouveau DRM driver taking care of the kernel mode-setting for this hardware. In fact, it mode-set correctly for dual-link DVI on a 30-inch Samsung 2560 x 1600 display for these two mid-range graphics cards.

Upgraded Kernel & Mesa Yield A Big Boost For Athlon R3 Graphics

Filed under
Graphics/Benchmarks
Ubuntu

With OpenArena the frame-rate went from just 8 FPS on Ubuntu 14.04 LTS to 19 FPS when using the Linux 3.14 kernel. Linux 3.14 allows for the R3 Graphics to re-clock to their highest performance state compared to Linux 3.13 where DPM isn't enabled by default for GCN GPUs. When going to Mesa 10.2-devel that will be officially released in about one month, the frame-rate rose to 25 FPS... That's over a three-fold performance improvement when pulling in the bleeding edge latest code.

Mozilla Firefox News and Opera Release

  • 2019 Add-ons Community Meetup in London

    At the end of October, the Firefox add-ons team hosted a day-long meetup with a group of privacy extension developers as part of the Mozilla Festival in London, UK. With 2019 drawing to a close, this meetup provided an excellent opportunity to hear feedback from developers involved in the Recommended Extensions program and to get input about some of our plans for 2020. [...] We recently announced that Firefox Preview, Mozilla’s next generation browser for Android built on GeckoView, will support extensions through the WebExtensions API. Members of the Android engineering team will build select APIs needed to initially support a small set of Recommended Extensions. The group discussed a wishlist of features for extensions on Android, including support for page actions and browser actions, history search, and the ability to manipulate context menus. These suggestions will be considered as work on Firefox Preview moves forward.

  • Here’s why pop culture and passwords don’t mix

    Were they on a break or not?! For nearly a decade, Ross and Rachel’s on-screen relationship was a point of contention for millions of viewers around the world. It’s no surprise to learn that years after the series finale, they are not only TV’s most beloved characters, but their names are popular account passwords, too. That’s right. More than thousands of internet users love Rachel, Monica, Joey, Chandler, Ross and Phoebe enough to use their names as passwords. Wondering about trends, we turned to haveibeenpwned (HIBP) — the website that aggregates data from known breaches — for pop culture favorites. (Firefox Monitor draws from HIBP to help people learn if they’ve been caught up in a data breach and take steps to protect themselves.) We couldn’t access any data files, browse lists of passwords or link passwords to logins — that info is inaccessible and kept secure — but we could look up random bad passwords manually on HIBP. It turns out, quite a lot of sitcom and sports fans are using pop culture passwords for their accounts. These bad passwords are not only weak, they have also been breached. Here’s what we spotted.

  • Adding CodeQL and clang to our Bug Bounty Program

    One of the ways we’re supporting this initiative at Mozilla is through renewed investment in automation and static analysis. We think the broader Mozilla community can participate, and we want to encourage it. Today, we’re announcing a new area of our bug bounty program to encourage the community to use the CodeQL tools.  We are exploring the use of CodeQL tools and will award a bounty – above and beyond our existing bounties – for static analysis work that identifies present or historical flaws in Firefox.

  • Opera Browser 65 Released with Redesigned Address Bar

    Opera web browser 65 was released a day ago with redesigned address bar, improved tracker blocker, and new bookmarks panel.

  • Opera 65 Launches with Much-Improved Tracker Blocker, Redesigned Address Bar

    Opera Software announced today the general availability of the Opera 65 web browser for desktop platforms, including GNU/Linux, macOS, and Windows, a release that brings a bunch of enhancements and new features. Based on Chromium 78, the Opera 65 web browser is here and it's better than ever, brining a much-improved tracker blocker that finally lets you see which trackers are tracking your digital footprint while you're surfing the Internet. Based on the EasyPrivacy Tracking Protection list, Opera's tracker blocker feature will now show you all the trackers following you and let you take action against them if you believe some aren't good for you. By default, the tracker blocker will automatically block known tracker scripts to speed up the loading of pages and keep your online activity private. In Opera 65, the built-in tracker blocker can be toggled on and off per site too.

Red Hat Leftovers

  • Red Hat Adds AI Capabilities to Process Automation Suite
  • Department of Defense Enlists Red Hat to Help Improve Squadron Operations and Flight Training

    Red Hat, Inc., the world's leading provider of open source solutions, today announced that the Department of Defense (DoD) worked with Red Hat to help improve aircraft and pilot scheduling for United States Marine Corps (USMC), United States Navy (USN) and United States Air Force (USAF) aircrews. Using modern development practices and processes from Red Hat Open Innovation Labs that prioritized end user needs, the project team identified unaddressed roadblocks and gained new skills to build the right solution, a digital "Puckboard" application, for their unique scheduling challenge. [...] The problem facing squadrons was seemingly straightforward: how to improve and digitize the management of flight training operations. The existing process was entirely manual, each representing pertinent information like a pilot’s name, associated with their training syllabus, location and time of flights. Simple at a glance, the number of cognitive variables contained within this undertaking made it stressful for the operator and difficult to scale across squadrons and bases. For more than a decade, various project teams within the DoD had tried to improve the system via custom built applications, aircraft scheduling software and hybrid solutions. None of these deployments withstood the test of time or could be replicated if the operator took a new role elsewhere. The Defense Innovation Unit (DIU), an organization tasked with accelerating commercial technologies into the military, took on this challenge.

  • It's RedHat, And Everyone Else

    As time passes, it appears that corporations are primarily considering one distribution when considering installing Linux, and that distro is clearly RedHat. That probably does not come as any major surprise, but it appears RedHat's dominance continues to get stronger. What use to be a landscape littered with a multitude of choices has nearly been rendered down to one. Wow! That didn't take long. The open source software dynamic seemed to be formed on the premise that users were never again going to be pigeon-holed into using one piece of software. Or, perhaps better stated, that was a byproduct of making the source code readily available. And, that is still true to this day. However, as a corporate citizen in today's business climate, one finds themselves with limited possibilities. It was a mere 20 years ago when the buzz of Linux was starting to hit its stride. Everywhere you looked, there was a different flavor of Linux. There were nearly too many to count. And, these were not just hobbyist distros. Instead, they were corporations rising like corn stalks all over the place. Sure, there were more dominant players, but one had the ability to analyze at least 10 different fully corporate supported distributions when making a decision. With that amount of possibilities, the environment was ripe for consolidation or elimination. And, we have all watched that take place. But, did we ever think we were going to find ourselves in the current predicament? The data that has been collected over the past five years paints a concerning picture. Even a mere five years ago, it seemed likely that at a minimum RedHat would always have Suse as a legitimate competitor. After all, those were the two distros that seemed to win the consolidation and elimination war. At least in the corporate space. As was widely reported during that time, RedHat had somewhere in the neighborhood of 70% marketshare. It was always the gorilla in the room. But, Suse was always looked upon as an eager and willing participant, no matter its stature, and tended to garner most of the remaining marketshare. That is the way it appeared for a length of time prior to this decline over the past few years.

  • Scale testing the Red Hat OpenStack Edge with OpenShift

    Red Hat Openstack offers an Edge computing architecture called Distributed Compute Nodes (DCN), which allows for many hundreds or thousands of Edge sites by deploying hundreds or thousands of compute nodes remotely, all interacting with a central control plane over a routed (L3) network. Distributed compute nodes allow compute node sites to be deployed closer to where they are used, and are generally deployed in greater numbers than would occur in a central datacenter. With all the advantages that this architecture brings, there are also several scale challenges due to the large number of compute nodes that are managed by the OpenStack controllers. A previous post details deploying, running and testing a large scale environment using Red Hat OpenStack Director on real hardware, but this post is about how we can simulate far greater scale and load on the OpenStack control plane for testing using containers running on OpenShift without needing nearly as much hardware. In order to prove the effectiveness of Red Hat's DCN architecture, we'd like to be able to get quantitative benchmarks on Red Hat Openstack's performance when many hundreds or thousands of compute nodes are deployed.
