openSUSE Leap 42.3 Linux OS to Reach End of Life on June 30th, 2019

Filed under
OS
SUSE

Launched on July 26, 2017, OpenSuSE Leap 42.3 was based on the SUSE Linux Enterprise (SLE) 12 Service Pack (SP) 3 operating system and it was powered by the long-term supported Linux 4.4 kernel series.

openSUSE Leap 42.3 was initially supposed to be supported until January 2019, but the openSUSE Project decided to give users six more months to upgrade to the latest openSUSE Leap 15 operating system series.

Now that openSUSE Leap 15.1 is here as the latest and greatest openSUSE Leap release, it's time for openSUSE Leap 42.3 users to upgrade their installations, and they only have one month to do that, until June 30th, 2019.

Linux

FriendlyElec’s $75, RK3399-based “SOM-RK3399” COM/SBC hybrid can stand alone or expand with a $120 “SOM-RK3399 Dev Kit” with -20 to 70℃ support and M.2 and mini-PCIe expansion.

Last year, FriendlyElec released two open-spec SBCs that ran Linux and Android on the hexa-core Rockchip RK3399: the $65 and up NanoPi M4 and the smaller, $50 NanoPi Neo4. Now, FriendlyElec has launched an RK3399-based SOM-RK3399 compute module for $75 that is available with a sandwich-style, $120 SOM-RK3399 Dev Kit. The module also qualifies as an SBC by dint of its dual USB Type-C ports.

The SOM-RK3399, which we saw on CNXSoft, is FriendlyElec’s second compute module after the Samsung S5P6818-based Smart6818 module found on its Octa-Core 64-bit AiO Android System touch-panel computer. Like Shenzhen Wesion’s RK3399-based Khadas Edge, it can operate standalone or be deployed as part of a sandwich-style SBC via an edge connector. The SOM-RK3399 is more COM-like than the Khadas Edge, which offers more real-world ports.

Ubuntu

Canonical and Ubuntu Linux founder Mark Shuttleworth recently said, "We have seen companies signing up for Linux desktop support, because they want to have fleets of Ubuntu desktop for their artificial intelligence engineers."

Dell has noticed, too.

Dell Senior Architect Barton George announced: "If mobile power is what you're looking for, you've come to the right place. And if AI is your need, the Precision 7540 and 7740 might just be what you've been looking for."

Linux PCs may never catch up with Windows on consumer laptops, but they are starting to make a bigger impression on developer laptops. Even Microsoft is now building Linux into Windows with Windows Subsystem for Linux. Why? Because today's developers are working on projects such as Kubernetes, AI, cloud-native computing, and machine learning, which live and die on Linux.

DragonFlyBSD's Kernel Optimizations Are Paying Off - 3 BSDs & 5 Linux OS Benchmarks On Threadripper

Filed under
Graphics/Benchmarks

DragonFlyBSD lead developer Matthew Dillon has been working on a big VM rework in the name of performance and other kernel improvements recently. Here is a look at how those DragonFlyBSD 5.5-DEVELOPMENT improvements are paying off compared to DragonFlyBSD 5.4 as well as FreeBSD 12 and five Linux distribution releases. With Dillon using an AMD Ryzen Threadripper system, we used that too for this round of BSD vs. Linux performance benchmarks.

The work by Dillon on the VM overhaul and other changes (including more HAMMER2 file-system work) will ultimately culminate with the DragonFlyBSD 5.6 release (well, unless he opts for DragonFlyBSD 6.0 or so). These are benchmarks of the latest DragonFlyBSD 5.5-DEVELOPMENT daily ISO as of this week benchmarked across DragonFlyBSD 5.4.3 stable, FreeBSD 12.0, Ubuntu 19.04, Red Hat Enterprise Linux 8.0, Debian 9.9, Debian Buster, and CentOS 7 1810 as a wide variety of reference points both from newer and older Linux distributions. (As for no Clear Linux reference point for a speedy reference point, it currently has a regression with AMD + Samsung NVMe SSD support on some hardware, including this box, prohibiting the drive from coming up due to a presumed power management issue that is still being resolved.)

Debian

MX Linux 18.3 is now available and ships with Linux kernel 4.19.37-2 and it's fully synced with the software repositories of the latest Debian GNU/Linux 9.9 "Stretch" operating system release, which means that it is fully patched against the recently disclosed Intel MDS (Microarchitectural Data Sampling) security vulnerabilities found in Intel microprocessors.

This release also includes an updated installer (mx-installer) that now lets users input system configuration selections during installation while the installer copies the system files to speed up the installation process. The UEFI boot installation was improved as well in MX Linux 18.3, which should now be compatible with more UEFI systems.

Linux
Reviews

Deepin Linux continues to show promise as a productive computing platform. This latest edition has fewer of the annoyances that plagued earlier releases.

The menus and internal dialogue boxes still have some Chinese characters. The potential user base is limited by a short list of available languages.

The ISO file on the standard download page is not a live session. It provides only a loadable interface to handle installation.

To get the live session ISO file, use the download page link in the previous paragraph. Then scroll to the bottom of the download options to the "Live Session Download" label and click the "Live Official Release" button.

  • Foliate is an Epic eBook Reader App for Linux Desktops

    Foliate is a new ebook reader app for Linux desktops whose streamlined, stylish GUI recently caught my eye.

    While I, personally, still find it easier to read ebooks on a dedicated e-reader device with an e-ink screen (like an Amazon Kindle) I do appreciate that there are features desktop ebook reader apps can offer that a dedicated e-reading device can not.

    Many of which you’ll find on offer in the ‘pages’ of Foliate, which pitches itself as a “simple and modern ebook viewer” for Linux desktops.

  • Lack of leadership in open source results in source-available licenses

    Don’t get me wrong — there will still be open source, lots and lots of it. But authors of open-source infrastructure software will put their interesting features in their “enterprise” versions if we as an industry cannot solve the Amazon problem.

    Unfortunately, the dark cloud on the horizon I wrote about back in November has drifted closer. Amazon has exhibited three particularly offensive and aggressive behaviors toward open source: [...]

  • Tantek Çelik: The @W3C Needs You: Please Vote For Change In The @W3CAB Election

    Please Vote in the 2019 W3C Advisory Board Election (W3C Member-only link, only Advisory Committee members can vote).

    My fellow Advisory Board (AB) candidates and additional members of the W3C Community have shared their thoughts on the AB election, some on their blogs, and some on W3C Member only list(s).

    It is very important that you explicitly rank candidates according to what is most important to you due to the way the current W3C STV mechanism is interpreted and implemented by the W3C Team. Past STV elections have shown that a Ranked 1 vote is crucial to candidates, Ranked 2 may have some impact, and the likelihood of effect drops off precipitously from there (though you should still rank at least a few more, ideally all candidates, just in case).

  • Huawei can now add the IEEE to the growing list of companies banning it

    "IEEE complies with US government regulations which restrict the ability of the listed Huawei companies and their employees to participate in certain activities that are not generally open to the public. This includes certain aspects of the publication peer review and editorial process," the organisation said.

  • Guest Post: Export Restrictions, Membership Organizations and Huawei

    New U.S. sanctions against Huawei in the escalating U.S. – China trade war have thrown another wrench into the gears of global commerce. But how do these sanctions affect standards organizations and open source development? The high level answer is that the impact will be significant for most standards organizations, and negligible for most open source projects. The major differentiator will be the degree of transparency of the organization in question.

    The details, and the answer for any given organization, however are much more complicated, and the political landscape remains dynamic and subject to change.

  • Microsoft’s Universal Windows Platform app dream is dead and buried

    Microsoft had a dream with Windows 8 that involved universal Windows apps that would span across phones, tablets, PCs, and even Xbox consoles. The plan was that app developers could write a single app for all of these devices, and it would magically span across them all. This dream really started to fall apart after Windows Phone failed, but it’s well and truly over now.

    Microsoft has spent years pushing developers to create special apps for the company’s Universal Windows Platform (UWP), and today, it’s putting the final nail in the UWP coffin. Microsoft is finally allowing game developers to bring full native Win32 games to the Microsoft Store, meaning the many games that developers publish on popular stores like Steam don’t have to be rebuilt for UWP.

    “We recognize that Win32 is the app format that game developers love to use and gamers love to play, so we are excited to share that we will be enabling full support for native Win32 games to the Microsoft Store on Windows,” explains Microsoft’s gaming chief Phil Spencer. “This will unlock more options for developers and gamers alike, allowing for the customization and control they’ve come to expect from the open Windows gaming ecosystem.”

  • Deliverable 1 : [✓]
    Seems okay, far better than the initial results. Although I should say, I deviated from what I thought I would need to write. First I assumed that I don’t have to write another boost::graph wrapper for KisPaintDevice, but I had to. That was one heck of an experience. In one of the last few posts, I ranted on Dmitry’s interpretation of the Graph, turns out we were on the same page but I understood his explanation the wrong way. I should put more attention to details from now on I guess. All the pixels are connected to each other, but they only have an edge between them if they are adjacent. If in center, the out degree would be 8, if in corners, 3 and if in edges, 5. There are some other cases too, but I will leave them for the moment. While writing the wrapper, I also got to know some of the cool features and techniques of C++, which I will be writing posts on as soon as I get some time, concepts, traits, avoiding virtual functions and what not. It is commendable that how boost approaches boost::astar_search, there is not a single virtual function, you don’t have to inherit anything (you can though for safety), just templates and traits, you are done.
  • Go Creeping In
    I’ve seen the inside of the Google and Amazon tech stacks. There are common threads that run through them and also, I bet, through most BigTechCos. Here and there down the stack is a lot of C++ and vestigial remnants from earlier days, Perl or PHP or whatever. Out in front of humans, of course, JS. But in between, there are oceans and oceans of Java; to a remarkable degree, it runs the Internet. Except for, here and there, you find a small but steadily increasing proportion of Go.
  • Stand by for FPR14 SPR1 chemspill
    Mozilla has shipped a fix for MFSA2019-18 in Firefox 67.0.3 and 60.7.1. This exploit has been detected in the wild, and while my analysis indicates it would require a PowerPC-specific attack to be exploitable in official TenFourFox builds (the Intel versions may be directly exploited, however), it could probably cause drive-by crashes and we should therefore ship an urgent fix as well. The chemspill is currently undergoing confidence tests and I'm shooting to release builds before the weekend. For builders, the only change in FPR14 SPR1 is the patch for bug 1544386, which I will be pushing to the repo just as soon as I have confirmed the fix causes no regressions.

All Linux, all the time: Supercomputers Top 500

Starting at the top, two IBM-built supercomputers, Summit and Sierra, at the Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee and Lawrence Livermore National Laboratory in California, respectively to the bottom -- a Lenovo Xeon-powered box in China -- all of them run Linux. Linux supports more hardware architectures than any other operating system. In supercomputers, it supports both clusters, such as Summit and Sierra, the most common architecture, and Massively Parallel Processing (MPP), which is used by the number three computer Sunway TaihuLight. When it comes to high-performance computing (HPC), Intel dominates the TOP500 by providing processing power to 95.6% of all systems included on the list. That said, IBM's POWER powers the fastest supercomputers. One supercomputer works its high-speed magic with Arm processors: Sandia Labs' Astra, an HPE design, which uses over 130-thousand Cavium ThunderX2 cores. And, what do all these processors run? Linux, of course. . 133 systems of the Top 500 supercomputers are using either accelerator or co-processor setups. Of these most are using Nvidia GPUs. And, once more, it's Linux conducting the hardware in a symphony of speed. Read more

  • Are DevOps certifications valuable? 10 pros and cons
  • Kubernetes 1.15: Enabling the Workloads
    The last mile for any enterprise IT system is the application. In order to enable those applications to function properly, an entire ecosystem of services, APIs, databases and edge servers must exist. As Carl Sagan once said, “If you wish to make an apple pie from scratch, you must first invent the universe.” To create that IT universe, however, we must have control over its elements. In the Kubernetes universe, the individual solar systems and planets are now Operators, and the fundamental laws of that universe have solidified to the point where civilizations can grow and take root. Discarding the metaphor, we can see this in the introduction of Object Count Quota Support For Custom Resources. In English, this enables administrators to count and limit the number of Kubernetes resources across the broader ecosystem in a given cluster. This means services like Knative, Istio, and even Operators like the CrunchyData PostgreSQL Operator, the MongoDB Operator or the Redis Operator can be controlled via quota using the same mechanisms that standard Kubernetes resources have enjoyed for many releases. That’s great for developers, who can now be limited by certain expectations. It would not benefit the cluster for a bad bit of code to create 30 new PostgreSQL clusters because someone forgot to add a “;” at the end of a line. Call them “guardrails” that protect against unbounded object growth in your etcd database.

Simple examples paired with the historic background will guide you from the beginning with a minimal Linux environment up to crafting secure containers, which fit perfectly into todays’ and futures’ orchestration world. In the end it should be much easier to understand how features within the Linux kernel, container tools, runtimes, software defined networks and orchestration software like Kubernetes are designed and how they work under the hood.
