Zorin OS 12 Improves Linux Desktop Access for Windows Users

Filed under
OS

There is a seemingly endless variety of Linux distributions in the marketplace, each attempting to carve out its own unique market niche. Zorin OS is one such flavor — a desktop-focused Linux distribution with the goal of helping Windows and macOS users to make the transition to Linux. Zorin OS 12, its latest milestone release, became generally available Nov. 18. Among the improvements in the new release is the updated Zorin Desktop 2.0, based on the open-source Gnome Shell. The new desktop provides users with redesigned icons and a new look for windows and navigation. A feature of Zorin worth noting is the ability to configure the desktop using Zorin Appearance, a tool that provides configurable options for layout, theme, fonts and panel display. Zorin OS also aims to help make the transition from Windows easier by directly integrating the Wine software compatibility layer, which enables many different types of Windows applications to run natively on Linux. Additionally, the included PlayOnLinux tool provides Zorin OS users with a menu of games, internet and office applications that can be installed easily. This slide show covers some of the key highlights of the Zorin OS 12 release.

SUSE buys HPE’s OpenStack and Cloud Foundry assets

Filed under
SUSE

SUSE, which probably is best known for its Linux distribution, has long been a quiet but persistent player in the OpenStack ecosystem. Over the last few months, though, the German company has also emerged as one of the stronger competitors in this world, especially now that we are seeing a good bit of consolidation around OpenStack.

Today, SUSE announced that it is acquiring OpenStack and Cloud Foundry (the Platform-as-a-Service to OpenStack’s Infrastructure-as-a-Service) assets and talent from the troubled HPE. This follows HPE’s decision to sell off (or “spin-merge” in HPE’s own language) its software business (including Autonomy, which HP bought for $11 billion, followed by a $9 billion write-off) to Micro Focus. And to bring this full circle: Micro Focus also owns SUSE, and SUSE is now picking up HPE’s OpenStack and Cloud Foundry assets.

Fedora 25 makes Linux easy enough for anyone to try

Filed under
Red Hat

When I got the heads-up that Red Hat was readying the release of Fedora 25, it caught my attention like any new release of a major Linux distribution would. But I was in for a pleasant surprise when I went to download a copy of the image.

The first thing to know about the new version of Fedora is that you don’t have to download an ISO file and write it to a USB stick. This is an important thing to note, as preparing installation media for Linux is one of the bigger hurdles for newbies. (When I say newbies, I think of my mom trying to download and properly burn a USB image.)

First open source RISC-V chips arrive in Arduino board

Filed under
OSS

SiFive’s Arduino ready “HiFive1” dev kit features its 320MHz FE310, the first MCU using the open RISC-V ISA. Also, Samsung is rumored to be using RISC-V.

In July, San Francisco-based startup SiFive unveiled the first SoCs based on the open source RISC-V platform: A Linux-ready octa-core Freedom U500 and a FreeRTOS-based Freedom E300. Now, the company has gone to Crowd Supply to sell an open source, Arduino compatible HiFive1 development board based on the FE300 that it claims is the fastest Arduino compatible in the world, 10 times faster even than Intel’s Arduino 101.

  • Outlook.com is still not functioning properly for some Microsoft punters

    Microsoft is still working to resolve "difficulties" faced by its Outlook customers, despite months of complaints about the disappearance of sent emails and 550 Errors.

    A growing number of complaints threads have been posted to Microsoft's questions page regarding Outlook after recent upgrades to the service. They both precede and follow last week's outage, which Redmond's PRs failed to explain to us.

  • OpenStack Becomes a Standard Building Block for NFV

    OpenStack is becoming the de facto standard for infrastructure orchestration for NFV deployment by leading Communications Service Providers (CSPs). CSPs are trading off the challenges of OpenStack implementations (e.g. immature technology and evolving standards) for the benefits of open source and open architectures (i.e. reduced vendor lock-in). Lack of standards for NFV management and orchestration (MANO) remains a leading impediment.

  • The Docker monitoring problem

    You have probably heard of Docker—it is a young container technology with a ton of momentum. But if you haven’t, you can think of containers as easily—configured, lightweight VMs that start up fast, often in under one second. Containers are ideal for microservice architectures and for environments that scale rapidly or release often.

    Docker is becoming such an important technology that it is likely that your organization will begin working with Docker soon, if it has not already. When we explored real usage data, we found an explosion of Docker usage in production: it has grown 5x in the last 12 months.

    Containers address several important operational problems; that is why Docker is taking the infrastructure world by storm.

    But there is a problem: containers come and go so frequently, and change so rapidly, that they can be an order of magnitude more difficult to monitor and understand than physical or virtual hosts. This article describes the Docker monitoring problem—and solution—in detail.

    We hope that reading this article will help you fall in love with monitoring containers, despite the challenges. In our experience, if you monitor your infrastructure in a way that works for containers—whether or not you use them—you will have great visibility into your infrastructure.

Kernel: Kernelci.org, Tripwire, Linux Foundation, R600 Gallium3D

  • Kernelci.org automated bisection
    The kernelci.org project aims at continuously testing the mainline Linux kernel, from stable branches to linux-next on a variety of platforms. When a revision fails to build or boot, kernel developers get informed via email reports. A summary of all the results can also be found directly on the website.
  • Securing the Linux filesystem with Tripwire
    While Linux is considered to be the most secure operating system (ahead of Windows and MacOS), it is still vulnerable to rootkits and other variants of malware. Thus, Linux users need to know how to protect their servers or personal computers from destruction, and the first step they need to take is to protect the filesystem. In this article, we'll look at Tripwire, an excellent tool for protecting Linux filesystems. Tripwire is an integrity checking tool that enables system administrators, security engineers, and others to detect alterations to system files. Although it's not the only option available (AIDE and Samhain offer similar features), Tripwire is arguably the most commonly used integrity checker for Linux system files, and it is available as open source under GPLv2.
  • Open Source Networking and a Vision of Fully Automated Networks
    Arpit Joshipura, Networking General Manager at The Linux Foundation, discussed open source networking trends at Open Source Summit Europe. Ever since the birth of local area networks, open source tools and components have driven faster and more capable network technologies forward. At the recent Open Source Summit event in Europe, Arpit Joshipura, Networking General Manager at The Linux Foundation, discussed his vision of open source networks and how they are being driven by full automation. “Networking is cool again,” he said, opening his keynote address with observations on software-defined networks, virtualization, and more. Joshipura is no stranger to network trends. He has led major technology deployments across enterprises, carriers, and cloud architectures, and has been a steady proponent of open source. “This is an extremely important time for our industry,” he said. “There are more than 23 million open source developers, and we are in an environment where everyone is asking for faster and more reliable services.”

  • Open-source software simulates river and runoff resources
    Freshwater resources are finite, unevenly distributed, and changing through time. The demand—and competition—for water is expected to grow both in the United States and in the developing/developed world. To examine the connection between supply and demand and resulting regional and global water stresses, a team developed Xanthos. The open-source hydrologic model is available for free and helps researchers explore the details and analyze global water availability. Researchers can use Xanthos to examine the implications of different climate, socioeconomic, and/or energy scenarios over the 21st century. They can then assess the effects of the scenarios on regional and global water availability. Xanthos can be used in three different ways. It can operate as an independent hydrologic model, driven, for example, by scenarios. It can serve as the core freshwater supply component of the Global Change Assessment Model, where multiple sectors and natural systems are modeled simultaneously as part of an interconnected, complex system. Further, it can be used by other integrated models and multi-model frameworks that focus on energy-water-land interactions.
  • “The Apache Way” — Open source done well
    I was at an industry conference and was happy to see many people stopping by the Apache booth. I was pleased that they were familiar with the Apache brand, yet puzzled to learn that so many were unfamiliar with The Apache Software Foundation (ASF). For this special issue, “All Eyes On Open Source”, it’s important to recognize not just Apache’s diverse projects and communities, but also the entity behind their success. Gone are the days when software and technology, in general, were developed privately for the benefit of the few. As technology evolves, the challenges we face become more complex, and the only way to effectively move forward to create the technology of the future is to collaborate and work together. Open Source is a perfect framework for that, and organizations like the ASF carry out a decisive role in protecting its spirit and principles.

  • 2017 - The Year in Which Copyright Went Beyond Source Code
    2017 was a big year for raising the profile of copyright in protecting computer programs. Two cases in particular helped bring attention to a myth that was addressed and dispelled some time ago but persists in some circles nonetheless. Many lawyers hold on to the notion that copyright protection for software is weak because such protection inheres in the source code of computer programs. Because most companies that generate code take extensive (and often successful) measures to keep source code out of the hands of third parties, the utility of copyright protection for code is often viewed as limited. However, copyright also extends to the “non-literal elements” of computer programs, such as their sequence, structure and organization, as well as to things such as screen displays and certain user interfaces. In other words, copyright infringement can occur when copying certain outputs of the code without there ever having been access to the underlying code itself.
  • Announcing WebBook Level 1, a new Web-based format for electronic books
    Eons ago, at a time BlueGriffon was only a Wysiwyg editor for the Web, my friend Mohamed Zergaoui asked why I was not turning BlueGriffon into an EPUB editor... I had been observing the electronic book market since the early days of Cytale and its Cybook but I was not involved into it on a daily basis. That seemed not only an excellent idea, but also a fairly workable one. EPUB is based on flavors of HTML so I would not have to reinvent the wheel. I started diving into the EPUB specs the very same day, EPUB 2.0.1 (released in 2009) at that time. I immediately discovered a technology that was not far away from the Web but that was also clearly not the Web. In particular, I immediately saw that two crucial features were missing: it was impossible to aggregate a set of Web pages into a EPUB book through a trivial zip, and it was impossible to unzip a EPUB book and make it trivially readable inside a Web browser even with graceful degradation. When the IDPF started working on EPUB 3.0 (with its 3.0.1 revision) and 3.1, I said this was coming too fast, and that the lack of Test Suites with interoperable implementations as we often have in W3C exit criteria was a critical issue. More importantly, the market was, in my opinion, not ready to absorb so quickly two major and one minor revisions of EPUB given the huge cost on both publishing chains and existing ebook bases. I also thought - and said - the EPUB 3.x specifications were suffering from clear technical issues, including the two missing features quoted above.

IBM code grandmaster: what Java does next

Reports of Java’s death have been greatly exaggerated — said, well, pretty much every Java engineer that there is. The Java language and platform may have been (in some people’s view) somewhat unceremoniously shunted into a side ally by the self-proclaimed aggressive corporate acquisition strategists (their words, not ours) at Oracle… but Java still enjoys widespread adoption and, in some strains, growing use and development.

  • Re-imagining beta testing in the ever-changing world of automation
    Fundamentally, beta testing is a test of a product performed by real users in the real environment. There are a number of names for this type of testing—user acceptance testing (UAT), customer acceptance testing (CAT), customer validation and field testing (common in Europe)—but the basic components are more or less the same. All involve user testing of the front-end user interface (UI) and the user experience (UX) to find and resolve potential issues. Testing happens across iterations in the software development lifecycle (SDLC), from when an idea transforms into a design, across the development phases, to after unit and integration testing.
