Linux Foundation in China (Today's Event Coverage)

  • Linus Torvalds Sees Lots of Hardware Headaches Ahead

    Linux founder Linus Torvalds, today at the KubeCon + CloudNative + Open Source Summit China conference, warned attendees that managing software is about to become a lot more challenging, largely because of two hardware issues that are beyond the control of DevOps teams.

    [...]

    In the meantime, Torvalds noted updates to the Linux kernel are still coming at a rate of every three months, and the Linux team is basically working on a six-month planning cycle—there is no master five-year plan the Linux team is working from. Roughly 1,500 developers work on contributions to the Linux kernel, with 100 maintainers overseeing the implementation of those contributions.

    Naturally, cybersecurity patches at the kernel level have significant implications for all of DevOps. Changes to the kernel need to be absorbed by all the various distributions of Linux, which in turn impacts all the stacks of software that depend on Linux. Jim Zemlin, executive director for The Linux Foundation, said that in the wake of the rise of these hardware issues and previous cybersecurity issues involving open source software such as the Heartbleed vulnerability, cybersecurity is the top priority for The Linux Foundation. As part of that effort, The Linux Foundation is researching various DevSecOps approaches to better securing the global open source supply chain, he said.

  • Linux Foundation to become home of WeBank’s FATE

    The Linux Foundation announced the inclusion of federated learning framework FATE into the organisation.

    The project has been contributed by Chinese digital bank WeBank, with organisations such as AI computing platform provider Clustar, e-commerce company JD.com’s subsidiary JD Intelligent Cities Research, and WeBank initiator Tencent already committed to the cause. 

    Linux Foundation’s executive director Jim Zemlin explained the move in a canned statement, saying “A secure computing framework is critical for developers who are using data and models to build the latest applications across financial services, manufacturing, healthcare and more.”

The open-spec “Khadas Vim3” SBC is on pre-order for $100 (2GB/16GB) or $140 (4GB/32GB) with an Amlogic A311D with a 5-TOPS NPU instead of the planned S922X. Other features include 40-pin GPIO, HDMI 2.1, MIPI-DSI and -CSI, USB 3.0 and Type-C, and M.2 with NVMe.

Shenzhen Wesion’s Khadas project announced the Khadas Vim3 in mid-May with the same Amlogic S922X found on Hardkernel’s Odroid-N2. Earlier this month it announced the June 24 launch date along with pricing of $70 (2GB/16GB) and $100 (4GB/32GB). Last week, however, a blog post announced a switch to the similar, but more powerful and AI-enhanced Amlogic A311D. Today, the board went on pre-order at $100 and $140 with the A311D, with shipments expected on Aug. 10.

Intel UMWAIT Support Queued For Linux 5.3 - New Feature For Tremont Cores

Filed under
Linux
Hardware

Adding to the growing list of features for the upcoming Linux 5.3 kernel is now Intel UMWAIT support for better power-savings.

UMWAIT is a new feature for Intel Tremont CPUs cores. UMWAIT can help enhance power savings during idle periods with "user mode wait" functionality. UMWAIT allows for monitoring a range of addresses in a lightweight power/performance state or an enhanced mode that can still help with conserving power but less so in order to offer lower latencies. UMWAIT is intended to be used as an alternative to kernel spinloops when needing to wait/sleep for short periods of time when the system is idle.

Five Linux Server Administration Mistakes And How To Avoid Them

Filed under
GNU
Linux
Server

In 2017, an employee at GitLab, the version control hosting platform, was asked to replicate a database of production data. Because of a configuration error, the replication did not work as expected, so the employee decided to remove the data that had been transferred and try again. He ran a command to delete the unwanted data, only to realize with mounting horror that he had entered the command into an SSH session connected to a production server, deleting hundreds of gigabytes of user data. Every seasoned system administrator can tell you a similar story.

The Linux command line gives server admins control of their servers and the data stored on them, but it does little to stop them running destructive commands with consequences that can’t be undone. Accidental data deletion is just one type of mistake that new server administrators make.

Fedora 31 Looking At No Longer Building i686 Linux Kernel Packages

Filed under
Linux
Red Hat

Not to be confused with Ubuntu's varying stance on dropping 32-bit packages beginning with their next release later this year, Fedora 31 now has a proposal pending to discontinue their i686 kernel builds but they will still be keeping with their 32-bit packaging.

This Fedora 31 change proposal by Justin Forbes, one of Fedora's kernel hackers, is just about ending i686 kernel builds beginning with this Fedora release due out in October. The i686 kernel-headers package would still be offered in order to satisfy necessary dependencies for 32-bit programs needing those headers. Of course, users will have to be running off a 64-bit kernel. All 32-bit programs should continue to work on Fedora 31.

Deprecating a.out Binaries

Filed under
Linux
Hardware

Remember a.out binaries? They were the file format of the Linux kernel till around 1995 when ELF took over. ELF is better. It allows you to load shared libraries anywhere in memory, while a.out binaries need you to register shared library locations. That's fine at small scales, but it gets to be more and more of a headache as you have more and more shared libraries to deal with. But a.out is still supported in the Linux source tree, 25 years after ELF became the standard default format.

Recently, Borislav Petkov recommended deprecating it in the source tree, with the idea of removing it if it turned out there were no remaining users. He posted a patch to implement the deprecation. Alan Cox also remarked that "in the unlikely event that someone actually has an a.out binary they can't live with, they can also just write an a.out loader as an ELF program entirely in userspace."

  • 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’m not going to go into all the nitty gritty of it in this post, but here’s a video from a LBRY advocate that does a good job of summarizing some of the issues by using clips from YouTube creators: 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

    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.

  • 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.
