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.

• Dirk Eddelbuettel: RcppArmadillo 0.9.400.2.0

  A new RcppArmadillo release based on the very recent Armadillo upstream release arrived on CRAN earlier today, and will get to Debian shortly.

  Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. 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. A service mesh manages services and the connections between them, whereas an API management solution manages APIs and their consumers. 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.

• OpenStack Looks to Help Define the Future of Open Infrastructure

  The OpenStack Foundation is continuing to grow its open-source efforts, including confirming new top-level projects and expanding its Ironic bare metal program, as part of the kickoff for the Open Infrastructure Summit.

  The Kata Containers secure container effort and the Zuul Continuous Integration/Continuous Deployment (CI/CD) projects have now been confirmed as top-level projects at the OpenStack Foundation, joining the group's namesake OpenStack cloud. While not yet a top-level project, the Airship lifecycle management project is also celebrating a major milestone with its 1.0 release.

  Additionally, the OpenStack Foundation is promoting its Ironic bare metal program as a way for organizations to deploy cloud resources on physical hardware.

• $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?

• ONLYOFFICE – document collaboration via blockchain and encryption

  Earlier in 2019 ONLYOFFICE announced the release of the end-to-end document encryption reinforced by blockchain. The new technology is available as a developer preview in the new version of ONLYOFFICE Desktop Editors.

  ONLYOFFICE is a project developed by Ascensio System SIA, with its in Riga (Latvia). Ascensio Systems designed OONLY OFFICE for internal team collaboration. However, an attempt to introduce it to a wider audience proved successful. In consequence, it revised and expanded functionality which has attracted use by more than 5M people (according to Ascensio Systems).

  ONLYOFFICE Desktop Editors is a free open-source office suite which comprises editors for documents, spreadsheets and presentations working offline. The suite also provides users with quick access to collaborative features.
