SUSE Manager 4: Traditional server management marries DevOps

Filed under
SUSE

Managing Linux servers has never been easy. Programs like Cockpit, cPanel, and Webmin use a GUI to make it simpler to handle common sysadmin tasks. But, with servers moving from the racks in your server room to the cloud and the edge and the Internet of Things (IoT), we need more. That's where DevOps comes in. And now programs like the new SUSE Manager 4 combine the best of both sysadmin approaches.

Daniel Nelson, SUSE VP of products and solutions, explained in a statement: "SUSE Manager manages physical, virtual, and containerized systems across edge, core, and cloud environments, all from a single centralized console. It's part of the IT transformation that lowers costs, reduces complexity, and boosts business agility."

Linux 5.2 + Mesa 19.2 Performance With Polaris/Vega/Vega20 vs. NVIDIA On Ubuntu 19.04

Filed under
Graphics/Benchmarks

With last week having delivered fresh benchmarks of the mid-range NVIDIA/AMD graphics cards using the very latest drivers, particularly the in-development Linux 5.2 and Mesa 19.2 components with the Radeon graphics cards tested, here is a similar comparison when moving up the spectrum and focusing on the higher-end graphics cards. Here's a look at how the RX 590, RX Vega 56, RX Vega 64, and Radeon VII are performing with the newest open-source AMD driver code compared to the NVIDIA Turing line-up backed by their latest binary driver.

While next month will be Radeon RX 5700 series Linux benchmarking using the newest code (DRM-Next / Linux 5.3), this article is offering a fresh look at how the Linux 5.2 kernel performance is shaping up on the higher-end graphics cards as complementary to last week's numbers. The four Radeon cards tested were using the Linux 5.2 Git kernel and Mesa 19.2-devel using the Oibaf PPA. The NVIDIA Pascal and Turing cards benchmarked were using their latest driver available, version 430.26.

Introducing GNOME Usage’s Storage panel

Filed under
GNOME

GNOME Usage is a new GNOME application to visualize system resources such as memory consumption and disk space. It has been developed by Petr Stetka, a high school intern in our Red Hat office in Brno. Petr is an outstanding coder for such a young fellow and has done a great job with Usage!

Usage is powered by libgtop, the same library used by GNOME System Monitor. One is not a replacement for the other, they complement our user experience by offering two different use cases: Usage is for the everyday user that wants to check which application is eating their resources, and System Monitor is for the expert that knows a bit of operating system internals and wants more technical information being displayed. Besides, Usage has a bit of Baobab too. It contains a Storage panel that allows for a quick analysis of disk space.

Android
OSS

While I'm of two minds when it comes to smartphones and tablets, I have to admit they can be useful. Not just for keeping in touch with people or using the web but also to do some work when I'm away from my computer.

For me, that work is writing—articles, blog posts, essays for my weekly letter, e-book chapters, and more. I've tried many (probably too many!) writing apps for Android over the years. Some of them were good. Others fell flat.

Here are four of my favorite open source Android apps for writers. You might find them as useful as I do.

How a trip to China inspired Endless OS and teaching kids to hack

Filed under
OS
Interviews

Last year, I decided to try out Endless OS, a lightweight, Linux-based operating system developed to power inexpensive computers for developing markets. I wrote about installing and setting it up. Endless OS is unique because it uses a read-only root file system managed by OSTree and Flatpak, but the Endless company is unique for its approach to education.

Late last year, Endless announced the Hack, a $299 laptop manufactured by Asus that encourages kids to code, and most recently the company revealed The Third Terminal, a group of video games designed to get kids coding while they're having fun. Since I'm so involved in teaching kids to code, I wanted to learn more about Endless Studios, the company behind Endless OS, The Third Terminal, The Endless Mission, a sandbox-style game created in partnership with E-Line Media, and other ventures targeted at expanding digital literacy and agency among children around the world.

I reached out to Matt Dalio, Endless' founder, CEO, and chief of product and founder of the China Care Foundation, to ask about Endless and his charitable work supporting orphaned children with special needs in China.

  • TensorFlow CPU optimizations in Anaconda

    By Stan Seibert, Anaconda, Inc. & Nathan Greeneltch, Intel Corporation TensorFlow is one of the most commonly used frameworks for large-scale machine learning, especially deep learning (we’ll call it “DL” for short). This popular framework has been increasingly used to solve a variety of complex research, business and social problems. Since 2016, Intel and Google have worked together to optimize TensorFlow for DL training and inference speed performance on CPUs. The Anaconda Distribution has included this CPU-optimized TensorFlow as the default for the past several TensorFlow releases. Performance optimizations for CPUs are provided by both software-layer graph optimizations and hardware-specific code paths. In particular, the software-layer graph optimizations use the Intel Math Kernel Library for Deep Neural Networks (Intel MKL-DNN), an open source performance library for DL applications on Intel architecture. Hardware specific code paths are further accelerated with advanced x86 processor instruction set, specifically, Intel Advanced Vector Extensions 512 (Intel AVX-512) and new instructions found in the Intel Deep Learning Boost (Intel DL Boost) feature on 2nd generation Intel Xeon Scalable processors. Let’s take a closer look at both optimization approaches and how to get these accelerations from Anaconda.

    I have a channel on YouTube for which I have lots of plans for. I started making videos last year and created 59 episodes for Debian Package of the Day. I’m proud that I got so far because I tend to lose interest in things after I figure out how it works or how to do it. I suppose some people have assumed that my video channel is dead because I haven’t uploaded recently, but I’ve just been really busy and in recent weeks, also a bit tired as a result. Things should pick up again soon.

Games: Steam Summer Sale, Last Moon, Ubuntu-Valve-Canonical Faceoff

  • Steam Summer Sale 2019 is live, here’s what to look out for Linux fans

    Another year, another massive sale is now live on Steam. Let’s take a look at what Valve are doing this year and what you should be looking out for.

    This time around, Valve aren’t doing any special trading cards. They’re trying something a little different! You will be entering the "Steam Grand Prix" by joining a team (go team Hare!), earning points for rewards and having a shot at winning some free games in the process. Sounds like a good bit of fun, the specific-game challenges are a nice touch.

  • Last Moon, a 2D action-RPG with a gorgeous vibrant style will be coming to Linux next year

    Sköll Studio managed to capture my attention recently, with some early footage of their action-RPG 'Last Moon' popping up in my feed and it looks gorgeous.

    Taking inspiration from classics like Legend of Zelda: A link to the past, Secret of Mana, Chrono Trigger and a ton more you can see it quite clearly. Last Moon takes in place in a once peaceful kingdom, where an ancient and powerful mage put a curse on the moon, as Lunar Knight you need to stop all this insanity and bring back peace.

  • Ubuntu Takes A U-Turn with 32-Bit Support

    Canonical will continue to support legacy applications and libraries.

    Canonical, the maker of the world’s most popular Linux-based distribution Ubuntu, has revived support for 32-bit libraries after feedback from WINE, Ubuntu Studio and Steam communities.

    Last week Canonical announced that its engineering teams decided that Ubuntu should not continue to carry i386 forward as an architecture. “Consequently, i386 will not be included as an architecture for the 19.10 release, and we will shortly begin the process of disabling it for the eoan series across Ubuntu infrastructure,” wrote Will Cooke, Director of Ubuntu Desktop at Canonical.

  • Steam and Ubuntu clash over 32-bit libs

    It has been a tumultuous week for gaming on Linux. Last Tuesday afternoon, Canonical's Steve Langasek announced that 32-bit libs would be frozen (kept as-is, with no new builds or updates) as of this October's interim 19.10 release, codenamed "Eoan Ermine." Langasek was pretty clear that this did not mean abandoning support for running 32-bit applications, however.

  • Linux gamers take note: Steam won’t support the next version of Ubuntu

    Valve has announced that from the next version of Ubuntu (19.10), it will no longer support Steam on Ubuntu, the most popular flavor of Linux, due to the distro dropping support for 32-bit packages,

    This all kicked off when Canonical, developer of Ubuntu, announced that it was seemingly completely dropping support for 32-bit in Ubuntu 19.10.

    However, following a major outcry, a further clarification (or indeed, change of heart) came from the firm stating that there will actually be limited support for 32-bit going forward (although updates for 32-bit libraries will no longer be delivered, effectively leaving them in a frozen state).

  • Valve killing Steam Support for some Ubuntu users

    A few years ago the announcement that Steam would begin supporting Linux was a big deal: it meant that anyone who preferred to rock an open-source operating system over Mac OS or Windows 10 would have instant buy-it-and-play-it access to a large catalog of game titles that would have otherwise taken a whole lot of tweaking to get up and running or wouldn't have worked for them at all. For some, at least, the party may be coming to an end.

  • Steam is dropping support for Ubuntu, but not Linux entirely

    The availability of Steam on Linux has been a boom for gaming on the platform, especially with the recent addition of the Steam Play compatibility layer for running Windows-only games. Valve has always recommended that gamers run Ubuntu Linux, the most popular desktop Linux distribution, but that's now changing.

  • Canonical (sort of) backtracks: Ubuntu will continue to support (some) 32-bit software

    A few days after announcing it would effectively drop support for 32-bit software in future versions of the Ubuntu operating system, Canonical has decided to “change our plan and build selected 32-bit i386 packages.”

    The company’s original decision sparked some backlash when it became clear that some existing apps and games would no longer run on Ubuntu 19.10 if the change were to proceed as planned.

    Valve, for example, announced it would continue to support older versions of Ubuntu, allowing users to continue running its popular Steam game client. But moving forward, the company said it would be focusing its Steam for Linux efforts on a different GNU/Linux distribution.

  • Just kidding? Ubuntu 32-bit moving forward, no word yet from Valve

    Due in part to the feedback given to the group over the weekend and because of their connections with Valve, Canonical did an about-face today. They’ve suggested that feedback from gamers, Ubuntu Studio, and the WINE community led them to change their plan and will “build selected 32-bit i386 packages for Ubuntu 19.10 and 20.04 LTS. Whether this will change Valve’s future with Ubuntu Steam, we’ll see.

  • Canonical backtracks on 32-bit Ubuntu cull, but warns that on your head be it

    CANONICAL HAS CONFIRMED a U-Turn on the controversial decision to drop 32-bit support for Ubuntu users later this year.

    The company has faced criticism from users who aren't happy with the plan to make Ubuntu purely 64-bit, which culminated at the weekend with Steam announcing it would pull support for Ubuntu. Many Steam games were never made in 64-bit and it would, therefore, devalue the offer.

    However, Canonical confirmed on Monday that following feedback from the community, it was clear that there is still a demand, and indeed a need for 32-bit binaries, and as such, it will provide "selected" builds for both Ubuntu 19.10 and the forthcoming Ubuntu 20.04.

    Canonical's announcement spoke of the highly passionate arguments from those who are in favour of maintaining both versions, thus forcing the team to take notice. However, it has made it clear that it's doing so under the weight of expectation, not because it agrees.

    "There is a real risk to anybody who is running a body of software that gets little testing. The facts are that most 32-bit x86 packages are hardly used at all," the firm said.

Hey advertisers, track THIS

Filed under
Moz/FF

If it feels like the ads chasing you across the internet know you a little too well, it’s because they do (unless you’re an avid user of ad blockers, in which case this is not for you). Earlier this month we announced Enhanced Tracking Protection on by default for new users in our flagship Firefox Quantum browser as a way to stop third-party cookies in their tracks. If you’re still not sure why you’d want to block cookies, today we’re launching a project called Track THIS to help you recognize what they do.

You’re being followed across the web through cookies—small data files stored by your browser—that remember things like language preferences, sites you’ve visited, or what’s in your shopping cart. That might sound generally fine, but it gets shady when data brokers and advertising networks also use cookies to collect information about your internet habits without your consent. You should still have control over what advertisers know about you—if they know anything about you at all—which can be tough when web trackers operate out of sight.

Richard Stallman: Drop the journalism charges against Julian Assange

Filed under
GNU

The US government has persecuted Julian Assange for a decade for Wikileaks' journalism, and now seeks to use his case to label the publishing of leaked secret information as spying.

The Free Software Foundation stands for freedom of publication and due process, because they are necessary to exercise and uphold the software freedom we campaign for. The attack on journalism threatens freedom of publication; the twisting of laws to achieve an unstated aim threatens due process of law. The FSF therefore calls on the United States to drop all present and future charges against Julian Assange relating to Wikileaks activities.

Accusations against Assange that are unrelated to journalism should be pursued or not pursued based on their merits, giving him neither better nor worse treatment on account of his journalism.
