  • Daniel Stenberg: QUIC and missing APIs

    I trust you’ve heard by now that HTTP/3 is coming. It is the next destined HTTP version, targeted to get published as an RFC in July 2019. Not very far off.

    HTTP/3 will not be done over TCP. It will only be performed over QUIC, which is a transport protocol replacement for TCP that always is done encrypted. There’s no clear-text version of QUIC.

  • Huge Supercomputers Still Exist. Here’s What They’re Being Used for Today

    The term “Supercomputer” implies one gigantic computer many times more powerful than your simple laptop, but that couldn’t be farther from the case. Supercomputers are made up of thousands of smaller computers, all hooked up together to perform one task. Each CPU core in a datacenter probably runs slower than your desktop computer. It’s the combination of all of them that makes computing so efficient. There’s a lot of networking and special hardware involved in computers of this scale, and it isn’t as simple as just plugging each rack into the network, but you can envision them this way, and you wouldn’t be far off the mark.

    Not every task can be parallelized so easily, so you won’t be using a supercomputer to run your games at a million frames per second. Parallel computing is usually good at speeding up very calculation-oriented computing.

    Supercomputers are measured in FLOPS, or Floating Point Operations Per Second, which is essentially a measure of how quickly it can do math. The fastest one currently is IBM’s Summit, which can reach over 200 PetaFLOPS, a million times faster than “Giga” most people are used to.

  • CloudLinux Dashboard — Now in Production

    The CloudLinux OS Team is excited to announce the CloudLinux Dashboard Production release for our valued server and hosting panel administrators. We believe that this product will firmly integrate into your workflow and greatly improve your performance when managing servers.

  • Google dominates code contributions across Cloud Native Computing Foundation projects

    Even without counting Kubernetes, Google is far and away the largest code contributor to the Cloud Native Computing Foundation (CNCF) open source group.

    Google accounts for 53% of all code commits to the Linux Foundation's CNCF and has seven times more contributions than Red Hat, which only accounted for 7.4% of the contributed code.

    The analysis of code contributions was done by Stackalytics, which is an open source code analysis framework that is hosted by the OpenStack Foundation and sponsored by Mirantis.

  • ON Semiconductor Increases Support for Idaho State University Department of Electrical Engineering

    ON Semiconductor continues its support of, and collaboration with, the Idaho State University Department of Electrical Engineering by recently donating an industrial-grade Linux server, eight state-of-the-art computer workstations and associated design software.

    The new workstations will be used to train ISU electrical engineering students, and eventually to provide professional graduate-level education to ON Semiconductor employees.

    “We have already started using the donated equipment for current coursework related to semiconductor design. In addition to the equipment and software donation, ON Semiconductor design engineers are working with us to create a new course that they will also help teach this spring.” said Steve Chiu, director of the ISU electrical engineering program.

  • How running websites has changed in the last two decades (for an Ars IT guru)

    I was a true nerd growing up in the 1980s—not in the hipster way but in the 10-pound-issue-of-Computer-Shopper-under-my-arm way (these things were seriously huge). I was thoroughly addicted to BBSes (Bulletin Board Systems) by the time I was 10. Maybe it's no surprise I ended up as a technical director for a science and tech site.

    In fact, I'd actually draw a direct line between the job of managing your own BBS (aka SysOping) to managing a modern Web infrastructure. And with everyone around Ars looking back given the site's 20th anniversary, let's make that line a bit clearer. It won't be an exhaustive history of websites, but here's how my own experiences with managing websites have evolved in the past two decades—plus how the tools and thinking have changed over time, too.

  • Kernel sources for the Nokia 8 Sirocco and Xiaomi Redmi Note 2/2 Pro/Note 3 (MediaTek) are now available

    Xiaomi’s kernel source release policy, as per my conversation with senior officials as well as official statements made by them, is that the company would aim to release the kernel source of a device within three months after its launch. This policy decision was to apply prospectively and not retrospectively, though the company did show interest in providing kernel sources for older devices as well as it was still bound by the GPL.

  • Help to spread the word about LibreOffice!

    Millions of people around the world use LibreOffice every day – but there are still some people who haven’t heard about our free, powerful, open source, Microsoft-compatible office suite.

  • Wayland's Weston Moving Towards Its Next Release Soon

    Longtime Wayland developer Derek Foreman is working on coordinating the next release of the Weston reference compositor. Here are those early details and his hope to ship this next feature release in March.

    Derek is tentatively proposing a February feature freeze and for this next Weston update to debut in March. At this time there are no plans for an updated Wayland release with there being no pressing changes on the horizon.

Nginx vs Apache: Which Serves You Best in 2019?

Filed under
Server
Web

For two decades Apache held sway over the web server market which is shrinking by the day. Not only has Nginx caught up with the oldest kid on the block, but it is currently the toast of many high traffic websites. Apache users might disagree here. That is why one should not jump to conclusions about which web server is better. The truth is that both form the core of complete web stacks (LAMP and LEMP), and the final choice boils down to individual needs.

For instance, people running Drupal websites often call on Apache, whereas WordPress users seem to favor Nginx as much if not more. Accordingly, our goal is to help you understand your own requirements better rather than providing a one-size recommendation. Having said that, the following comparison between the two gives an accurate picture.

Red Hat Advances Container Technology With Podman 1.0

Filed under
Red Hat
Server

Red Hat announced the 1.0 release of its open-source Podman project on Jan. 17, which provides a fully featured container engine.

In Podman 1.0, Red Hat has integrated multiple core security capabilities in an effort to help enable organizations run containers securely. Among the security features are rootless containers and enhanced user namespace support for better container isolation. Containers provide a way for organizations to run applications in a virtualized approach on top of an existing operating system. With the 1.0 release, Red Hat is now also positioning Podman as an alternative to the Docker Engine technology for application container deployment.

"We felt the sum total of its features, as well as the project's performance, security and stability, made it reasonable to move to 1.0," Scott McCarty, product manager, Containers, Red Hat, told eWEEK. "Since Podman is set to be the default container engine for the single-node use case in Red Hat Enterprise Linux 8, we wanted to make some pledges about its supportability."

Server Side Public License (SSPL) Fallout

  • Red Hat drops MongoDB over concerns related to its Server Side Public License (SSPL)

    It was last year in October when MongoDB announced that it’s switching to Server Side Public License (SSPL). Now, the news of Red Hat removing MongoDB from its Red Hat Enterprise Linux and Fedora over its SSPL license has been gaining attention.

  • The Need for Sustainable Open Source Projects

    The point of the article is a lot of companies that support open source projects, like RedisDB, are moving to more closed source solutions to survive. The cloud providers are called out as a source of a lot of problems in this article, as they consume a lot of open source software, but do not really spend a lot of time or effort in supporting it. Open source, in this situation, becomes a sort of tragedy of the commons, where everyone thinks someone else is going to do the hard work of making a piece of software viable, so no-one does any of the work. Things are made worse because the open source version of the software is often "good enough" to solve 80% of the problems users need solved, so there is little incentive to purchase anything from the companies that do the bulk of the work in the community.

  • MongoDB’s licensing changes led Red Hat to drop the database from the latest version of its server OS

    After MongoDB decided last year that it was changing the license for its open-source database to a more restrictive version, Red Hat decided it would no longer include MongoDB in the latest version of its flagship Red Hat Enterprise Linux operating system.

    The change apparently went unnoticed until a Hacker News thread took off earlier today, but it was included in the release notes for RHEL 8.0, which was released in beta last November. In those notes, Red Hat states “note that the NoSQL MongoDB database server is not included in RHEL 8.0 Beta because it uses the Server Side Public License (SSPL).”

MariaDB Platform X3

OSS
  • Unlock Hybrid Everything with MariaDB Platform X3

    As customers, we expect businesses to provide us with useful information. And as our expectations rise, so too must the usefulness of the information. For example, it’s useful to know a product is on sale. It’s more useful to know that it will be sold-out within hours. It’s also useful to know the balance on my credit card. But it’s even more useful to know if it’s going be higher than the automated payment I scheduled.

  • MariaDB Platform X3 combines transaction processing and analytics

    With MariaDB Platform X3, an organization may use a single database both for conventional customer-facing workloads (transactional, or OLTP) and internal business-intelligence workloads (analytical, or OLAP). The same data is available for either kind of work and is kept automatically in sync between the two sides.

    MariaDB Platform is priced at a flat per-node cost, regardless of whether nodes are OLTP or OLAP. This allows for more flexible deployments, where the number of nodes in a given deployment can be moved freely between OLTP and OLAP workloads as demand changes.

  • Puppet on DevOps: practitioners (not managers) are the new champions

    With a foundation in open source, Puppet is championing a world of what it calls ‘unconstrained software change’… presumably an even more intense version of Continuous Integration (CI) and Continuous Delivery (CD).

  • Architectural learning curve for the private cloud

    Just about everybody is familiar with Docker; about half as many know Kubernetes. But how about Istio? Docker and Kubernetes may be the foundation of your private cloud, but it turns out they might not be enough.

    Here are some very interesting and easily accessible numbers from Twitter: Docker has 304,000 followers and Kubernetes has 121,000. On the other hand, Helm, Istio and Prometheus Monitoring have fewer than 15,000 followers each.

  • SUSE Server for Arm Becomes Generally Available

    The SUSE server (SLES) for Arm processors is now available directly from SUSE with a new price structure that counts cores and sockets.

  • The curious case of the Raspberry Pi in the network closet

    I asked him to unplug it, store it in a safe location, take photos of all parts and to make an image from the SD card (since I mostly work remote). I have worked on many Raspberry Pi projects and I felt confident I could find out what it does.

    At this point nobody thought it was going to be malicious, more like one of our staffers was playing around with something.

  • Leveraging OpenShift or Kubernetes for automated performance tests (part 3)

    This is the third of a series of three articles based on a session I held at EMEA Red Hat Tech Exchange. In the first article, I presented the rationale and approach for leveraging Red Hat OpenShift or Kubernetes for automated performance testing, and I gave an overview of the setup. In the second article, we looked at building an observability stack. In this third part, we will see how the execution of the performance tests can be automated and related metrics gathered.

  • Ansible vs. Puppet: Declarative DevOps tools square off

    DevOps aims to drive collaboration between development and operations teams, but software quality drives DevOps adoption more than any other factor. As this comparison of Ansible vs. Puppet shows, software quality dramatically influences DevOps tools.

    Software quality tends to be an organizational goal or a staff function, not the dominion of a dedicated group with broad responsibility to implement its decisions. Effective software quality efforts involve everyone from development to production users to ensure real value.

  • MAAS 2.5 : Growing the ecosystem and support for KVM micro-clouds

    Our latest release makes for a very exciting point in the MAAS evolution. As datacenter (DC) infrastructure grows at unparalleled scale fueled by new applications and services such as connected autonomous cars, augmented/virtual reality (AR/VR) and IoT, the need for automated bare metal provisioning has never been more important. Multi-access edge computing and the ongoing shift to 5G will continue to drive cloud architectures ranging from small clusters deployed at actual radio towers all the way to thousands of nodes running in core data centres.

    The agility and speed of discovering, allocating and also repurposing bare-metal servers will be crucial to new services and an automated physical infrastructure lifecycle management. MAAS 2.5 brings new capabilities and improvements to how this can be achieved in a repeatable and reliable way.

  • Container Storage Interface (CSI) for Kubernetes GA

    The Kubernetes implementation of the Container Storage Interface (CSI) has been promoted to GA in the Kubernetes v1.13 release. Support for CSI was introduced as alpha in Kubernetes v1.9 release, and promoted to beta in the Kubernetes v1.10 release.

    The GA milestone indicates that Kubernetes users may depend on the feature and its API without fear of backwards incompatible changes in future causing regressions. GA features are protected by the Kubernetes deprecation policy.

  • Happy Birthday, Chef!

    With Chef, you can automate the way your infrastructure is configured, deployed, and managed. When you’re operating with a single machine, configuration management can be fairly simple. But what happens when your organization scales up? That’s where Chef comes in and saves the day — and a whole lot more.

    Chef ensures your configurations are standardized and continuously enforced in every environment and at any scale. It allows your infrastructure configurations to be testable, portable, and auditable, saving your organization time and monetary resources. You could say Chef is a superhero with all the saving it does.

  • Community collaboration makes for some great OpenStack solutions

    If you follow the evolution of OpenStack, you know how it’s finding its way into all sorts of workloads, from high-level research to car manufacturing to all-new 5G networks. Organizations are using it for everything from the mundane to the sublime and sharing what they’re learning with the OpenStack community.

    Some of the examples offered up at the recent OpenStack Summit Berlin showed that OpenStack is a full-fledged part of the IT mainstream, which means there are a wealth of ideas out there for your own implementation.

Out-Of-The-Box 10GbE Network Benchmarks On Nine Linux Distributions Plus FreeBSD 12

Last week I started running some fresh 10GbE Linux networking performance benchmarks across a few different Linux distributions. That testing has now been extended to cover nine Linux distributions plus FreeBSD 12.0 to compare the out-of-the-box networking performance. Tested this round alongside FreeBSD 12.0 was Antergos 19.1, CentOS 7, Clear Linux, Debian 9.6, Fedora Server 29, openSUSE Leap 15.0, openSUSE Tumbleweed, Ubuntu 18.04.1 LTS, and Ubuntu 18.10. All of the tests were done with a Tyan S7106 1U server featuring two Intel Xeon Gold 6138 CPUs, 96GB of DDR4 system memory, and Samsung 970 EVO SSD. For the 10GbE connectivity on this server was an add-in HP NC523SFP PCIe adapter providing two 10Gb SPF+ ports using a QLogic 8214 controller. Read more
