Fedora 30 Performance Is Moving In The Right Direction But A Lot Of Untapped Potential

Filed under
Graphics/Benchmarks

Yesterday we began with our preliminary performance benchmarks of Fedora 30. From those results Intel Core i9 and AMD Threadripper systems and what we're seeing on other systems in the labs, Fedora 30 indeed is coming out generally slightly faster than Fedora 29 when looking at the performance overall. In some cases the performance is much better thanks to GCC 9 and other upgrades, but overall it's a small, modest performance improvement. While that's better than seeing Fedora 30 running slower than its predecessor, there still is more potential to squeeze out of the system.

With the Intel Core i9 7980XE system as a high-performance reference system, here are some additional data points comparing those Fedora 29 and Fedora 30 results to Ubuntu 19.04, openSUSE Tumbleweed (with its GNOME desktop option, to match the other operating systems tested), and Clear Linux for seeing how those distributions compete with the new Fedora Linux.

The RaspAnd Pie Build 190429 is here a month and a half after the first release that brought Google's latest Android 9 Pie mobile operating system to the tiny Raspberry Pi computers, which, unfortunately, did not ship with Google Play Store, though you could install Android apps via the Aptoide package manager.

The new release adds Yalp Store, a replacement for Google Play store that lets you install Android apps directly from Google Play Store in the APK file format. You don't even need to have a Google account to install Android apps, except if you want to install paid apps or access your owned apps or write reviews.

RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 587 other packages on CRAN.

  • The Best of Both Worlds

    Linux desktop users can now use an estimated two million Android apps that were previously unavailable on Linux with VolksPC OS.

    Open source enthusiasts have spent years waiting for the Linux desktop revolution. The Linux environment now supports hundreds of useful, stable, and secure desktop tools that are available for no cost, but Linux still has not displaced Windows or macOS in the race for desktop marketshare.

    Android, however, which uses the Linux kernel, has actually become mainstream and is competing quite well. In fact, if you combine desktop, laptop, tablet, and mobile usage, Android has reached 38 percent of marketshare, narrowly overtaking Windows as the most popular operating system in the world.

  • Rancher Labs Adds OS Optimized for Kubernetes

    Rancher Labs has made available a beta release of a lightweight operating system on which it envisions IT organizations will deploy its previously announced lightweight instance of Kubernetes dubbed k3s.

    Company CEO Sheng Liang says the main goal is to make it more convenient for IT organizations to use the same set of tools to deploy an instance of Kubernetes along with a k3OS operating system based on the open source Ubuntu kernel. Rancher Labs doesn’t envision IT organizations replacing instances of Linux that have already been deployed in with K3OS, but in circumstances where there has been no operating system standard set, k3OS should provide a more frictionless deployment option, he says.

    In fact, Liang notes the ability to deploy and update Kubernetes and the operating system it runs on from within the same user interface to access a common set of YAML files should be especially appealing to IT organizations that have embraced best DevOps processes to deliver ongoing rolling upgrades to their IT environments.

  • Manage your APIs deployed with Istio service mesh

    And, as explained in “Distributed microservices architecture: Istio, managed API gateways and, enterprise integration”, a service mesh does not relieve the need for an API management solution.

In this article, I’ll describe how to manage APIs using the Red Hat Integration adapter for Istio.

    Red Hat Integration offers an API management capability that let companies build an ecosystem of consumers around their APIs and then drive new revenue from them.

    The third beta of the Qt 5.13 tool-kit is now available for testing as the developers try to get this update ready to ship as stable in May. 

    Jani Heikkinen of The Qt Company announced this third beta today. A fourth beta is expected as they are still working to update from OpenSSL 1.0 to 1.1 this cycle. Following that, a release candidate will come once their blocker bugs are addressed. As of writing, there are just nine blocker bugs at present ranging from Android crashes to pulling in new Chrome patches to WebAssembly issues.

  • FOSSPicks

    Kdenlive is one of those applications that catches you by surprise. One minute it seems little more than a quick Qt-built GUI wrapped around some command-line tools to concatenate video files, and the next minute it's spending months on hiatus being rewritten and refactored into something that can genuinely start to compete with Final Cut Pro on macOS. This is what's happening with Kdenlive; you'll find the all new version in the KDE Applications 19.04 release. To be fair, it already was the best open source video editor available, barring perhaps Blender if you needed absolute power and had the patience to master its idiosyncratic user interface.

    Many who have perhaps not used Kdenlive for a while won't realize that it now includes some rather advanced features. One, for example, allows you to use low quality copies of a clip as proxies for edits you want to make. This saves CPU and storage resources and is perfect for our 8K future. There's also a brilliant Title Editor toolbar that enables you to create 2D text frames without having to resort to an external package. This important function is always overlooked in open source video editors, as they often focus on performance and clip editing. However, adding titles is equally important. You only have to look at the most popular YouTube videos to see how words, spacing, shadows, gradients, and images are spliced into video segments to create a professional and snappy video. Dropping an alpha-blended Gimp text render doesn't really cut it, unless you're creating a video about Gimp. Kdenlive has done all this for some time, which has perhaps been our only criticism: It was difficult to see where new developments were taking the project.

  • $2.4 Million in Prizes for Schools Teaching Ethics Alongside Computer Science

    Today, we are announcing the first winners of the Responsible Computer Science Challenge. We’re awarding $2.4 million to 17 initiatives that integrate ethics into undergraduate computer science courses.

    The winners’ proposed curricula are novel: They include in-class role-playing games to explore the impact of technology on society. They embed philosophy experts and social scientists in computer science classes. They feature “red teams” that probe students’ projects for possible negative societal impacts. And they have computer science students partner with local nonprofits and government agencies.

    The winners will receive awards of up to $150,000, and they span the following categories: public university, private university, liberal arts college, community college, and Jesuit university. Stage 1 winners are located across 13 states, with computer science programs ranging in size from 87 students to 3,650 students.

    The Responsible Computer Science Challenge is an ambitious initiative by Omidyar Network, Mozilla, Schmidt Futures, and Craig Newmark Philanthropies. It aims to integrate ethics and responsibility into undergraduate computer science curricula and pedagogy at U.S. colleges and universities.

  • Confronting linguistic bias: The case for an open human language

    Open source—that is, making the code of digital tools and datasets accessible to anyone—is a popular approach to improving the methodological transparency of this work in educational organizations. The field's broader open access movement stresses skepticism about the proprietary nature of algorithms, data, and code involved in humanistic research more generally—and cautions researchers about the impact that ownership can have on the research process itself.

    This perspective has tremendous implications for the way we think about the embedded biases and assumptions in humanistic research. What if we subjected our human languages to the same rigorous assessment we do with our computational languages? What biases might we discover in them? How might those biases impact our scholarship?

  • The decade long wait for Bash 5

    It's a coincidence that the Linux kernel and Bash jumped to version 5.0 at about the same time. While Linus assigns the numbers as he sees fit, Bash changes its version when major adjustments are made. Here's what users can expect in Bash 5.

    My last article about a Bash version change is 10 years old [1]. Version 4 was in the starting blocks at that time, but it took some time for all distributions to switch to this version. Nobody puts their production system at risk without good reason.

    Nevertheless, the change was very attractive for developers of complex scripts, because – thanks to associative arrays – a completely new data structure was introduced. The advantages were more elegant, simpler programs that were also easier to maintain. Other important changes included the coproc command (which supports parallelization) and redirection operators.

  • Stack Clash mitigation in GCC: Why -fstack-check is not the answer

    In our previous article about Stack Clash, we covered the basics of the Stack Clash vulnerability. To summarize, an attacker first uses various means to bring the heap and stack close together. A large stack allocation is then used to “jump the stack guard.” Subsequent stores into the stack may modify objects in the heap or vice versa. This, in turn, can be used by attackers to gain control over applications.

    The company said it had also unlinked Docker Hub from GitHub and Bitbucket for those using these external repositories to automatically build — or autobuild — container images. Such users will need to relink their Docker Hub accounts to these repositories in order for autobuild to work properly.

  • OpenStack Keeps One Eye on the Prize, One Over Its Shoulder
    The OpenStack Foundation (OSF) used its recent Open Infrastructure Show (OIS) to remind the open source community of its importance, maturity, and flexibility. But the event also showed that the group understands that the virtualized infrastructure environment is evolving rapidly. I must admit that heading into the OIS event I was not expecting much. Conversations I have had over the past year continued to show a strong core of OpenStack supporters, but it seemed that the platform’s innovative spirit was diminishing. And in such a rapidly evolving technology segment, any sort of diminishing momentum is the equivalent of going backwards.

    It is an open-source, accelerated-math library designed to help developers build and train machine-learning models using a wide range of hardware — CPUs, GPUs, and even specialized chips such as TPUs (Tensor Processing Units). While TensorFlow was originally designed for use with more powerful machines, it has evolved to be able to create models to run in all sorts of unlikely places, from browsers to low-power IoT devices. Today, TensorFlow can be used with a wide range of programming languages, including Python, Go, C++, Java, Swift, R, Julia, C#, Haskell, Rust, and JavaScript.
  • Google extends lowRISC FOSSi partnership
    Unlike proprietary processors, the design and instruction set architecture (ISA) for which are kept behind a typically expensive licence wall, free and open source silicon (FOSSi) does what it says on the tin: Projects like RISC-V provide both the ISA and key implementations under permissive licences, allowing anyone to use, modify, distribute, and commercialise the technology without a single license or royalty payment - including, in many cases, the ability to create a proprietary implementation, should they so choose. Following on from the news that it was a founding member of the Linux Foundation's CHIPS Alliance, an industry group set up to 'host and curate high-quality open source code relevant to the design of silicon devices', Google has now announced that it is extending its existing partnership with the lowRISC project to include additional funding, support, and the appointment of two Google staffers as board members on the project.

  • To Create Prosperity, Free Market Competition Isn’t Enough—You Need Collaboration Too
    What’s ironic is that all of this communal activity isn’t driven by beret-wearing revolutionaries plotting in coffee houses, but by many of today’s most powerful and profit-driven corporations, who act not out of altruism, but self-interest. The fact is that technology firms today who do not actively participate in open source communities are at a significant competitive disadvantage. For example, Chris DiBona, Director of Open Source at Google, once told me, “We released Android as an open source product because we knew that was the fastest way to grow adoption, which enabled us to preserve the relationships with customers for businesses like search, maps and Gmail.” That is the reality of today’s marketplace. You collaborate in order to compete effectively. Businesses that don’t accept that simple fact will find it difficult to survive. Science’s commitment to communal effort is not at all new, but is a thread running deep in America’s long history of technological dominance. And it’s not all about private companies competing with each other, either: it’s about how the market can benefit from public investment. When Vannevar Bush submitted his famous report, “Science, The Endless Frontier,” to President Truman at the end of World War II, he argued that scientific discovery should be considered a public good crucial to the competitiveness of the nation. The crux of his argument is that such efforts build capacity through creating what he called “scientific capital” and pointed out that “New products and new processes do not appear full-grown. They are founded on new principles and new conceptions, which in turn are painstakingly developed by research in the purest realms of science.”

  • The benefits of open source networking for enterprise IT
    Open source software has proved its benefits for various aspects of the IT community in terms of costs, agility and flexibility. Open source networking software is in its early stages of deployment among enterprises. Meantime, hyperscale cloud providers and the largest service providers have made effective use of open source networking. It is standard in large IT organizations to consider open source software alongside packaged software and SaaS as part of their IT architecture. Enterprise IT shops frequently deploy open source software in test environments and when designing new applications, like in DevOps. IT organizations report a range of benefits from open source software, including innovative design, time to market and agility. While open source software helps reduce some costs, deployment in production environments is generally accompanied by a vendor-supplied support contract.
  • How “Lab as a Service” supports OPNFV and ONAP development
    The Interoperability Lab at the University of New Hampshire (UNH-IOL) is a community resource that allows developers and open source users to have access to resources that they might not have themselves. The “Lab as a Service” provides the necessary shared compute and networking resources for developers working on projects such as OPNFV. Access is remote via a VPN connection, so it acts like a remote server. Those new to OPNFV can create a virtual deployment on a single node and run small VNFs on top. It gives developers access to a bare metal system for low level checking and installs. The next step is to add better support for multi-node usage, integrating the CI work that's being done in the OPNFV project and making the system more compatible with ONAP development.

  • Exclusive: Google suspends some business with Huawei after Trump blacklist
  • 5G and #Huawei – Trade wars can be prevented by using Open Source
    Consumer Choice Center Managing Director Fred Roeder stressed that more openness and transparency of telephone and radio networks could lead to more trust in the soft- and hardware of infrastructure providers: “Outright bans by country of origin should only be the last resort for policy makers. Bans risk getting the global economy deeper into costly trade wars. Consumers benefit from competition and the fast rollout of new technologies such as 5G networks. At the same time, we are worried about vulnerabilities and potential backdoors in equipment and software. Closed systems have a much higher likelihood of hiding vulnerabilities. Hence more open systems and open source approaches can really help consumers, and governments, trust the security promises of 5G providers,” said Roeder. “Private efforts such as the Open Radio Access Network Alliance show that open source systems are an option for telecommunication infrastructure. It would be a win-win situation for consumers and industry if more companies would embrace open standards. An open source approach in telecommunications could revolutionize market access and rollout pace of new standards in the era of 5G, in the same way as blockchain does in the financial services and payment industry. Manufacturers that commit to open source systems show that they don’t have any vulnerabilities to hide, and at the same time have a compelling case not to be excluded on the basis of their country of origin,” he added.
  • Why 5G is a huge future threat to privacy
    The next-generation of mobile communications, 5G, is currently a hot topic in two very different domains: technology – and politics. The latter is because of President Trump’s attempts to shut the Chinese telecoms giant Huawei out of Western procurement projects. That might work in the US, but the move is meeting a lot of resistance in Europe. There seem to be two primary concerns about allowing Chinese companies to build the new 5G infrastructure. One is a fear that it will help China consolidate its position as the leading nation in 5G technologies, and that it could come to be the dominant supplier of 5G hardware and software around the world. The other is more directly relevant to this blog: a worry that if Chinese companies install key elements of 5G systems, they will be able to spy on all the traffic passing through them. As the South China Morning Post reports, in an attempt to soothe those fears, Huawei has even promised to sign “no-spy agreements with governments“. That’s a rather ridiculous suggestion – as if signing an agreement would prevent Chinese intelligence agencies from using Huawei equipment for surveillance if they could.
