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.)

NVIDIA GTX 680 To GTX 1080 Blender OpenCL Benchmarks

Filed under
Graphics/Benchmarks

For this article are benchmarks of 13 Kepler/Maxwell/Pascal NVIDIA GeForce graphics cards when testing Blender 2.78's OpenCL renderer. Unfortunately, no AMD OpenCL benchmarks for Blender yet -- the current open-source stack doesn't work until ROCm OpenCL support comes into play and the AMDGPU-PRO stack wasn't working for Blender OpenCL but was falling back to CPU rendering.

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.

This week in KDE: fixing up Plasma 5.20

Okular’s editable forms are no longer mis-rendered when inertially scrolling (Kezi Olio, Okular 1.11.2) When your scanner can almost but not quite fit a particular page size, Skanlite will now display the option to scan to that page size anyway (e.g. 215mm wide scan beds now give you the option to scan using the US Letter page size) (Kåre Särs, libksane 20.12) The text of Elisa’s keyboard shortcuts are now translated properly (Nikunj Goyal, Elisa 20.12) Clearing the clipboard history on Wayland no longer crashes Plasma (David Edmundson, Plasma 5.20) Improved the Plasma SVG cache heuristics such that various things which might sometimes be invisible after upgrading Plasma now show up like they’re supposed to (Arjen Hiemstra, Plasma 5.20) On Wayland, clicking on a Task Manager entry while that entry’s tooltip is visible no longer crashes Plasma (Vlad Zahorodnii, Plasma 5.20) On Wayland, clicking on a Task Manager thumbnail now activates that window, as you would expect (Marco Martin, Plasma 5.20) Read more Also: KDE Plasma 5.20 Should Be Crashing A Lot Less Under Wayland

Legacy: Dennis Ritchie's Lost Dissertation and FTP Fadeout

  • Discovering Computer Legend Dennis Ritchie's Lost Dissertation
  • FTP Fadeout

    Here’s a small piece of news you may have missed while you were trying to rebuild your entire life to fit inside your tiny apartment at the beginning of the COVID crisis: Because of the way that the virus shook up just about everything, Google skipped the release of Chrome version 82. Who cares, you think? Well, users of FTP, or the File Transfer Protocol. During the pandemic, Google delayed its plan to kill FTP, and now that things have settled to some degree, Google recently announced that it is going back for the kill with Chrome version 86, which deprecates the support once again, and will kill it for good in Chrome 88. (Mozilla announced similar plans for Firefox, citing security reasons and the age of the underlying code.) It is one of the oldest protocols the mainstream [Internet] supports—it turns 50 next year—but those mainstream applications are about to leave it behind. Today’s Tedium talks about history of FTP, the networking protocol that has held on longer than pretty much any other.

virt-manager 3.0.0 released!

Yesterday I released virt-manager 3.0.0. Despite the major version number bump, things shouldn't look too different from the previous release. For me the major version number bump reflects certain feature removals (like dropping virt-convert), and the large amount of internal code changes that were done, though there's a few long awaited features sprinkled in like virt-install --cloud-init support which I plan to write more about later.

  • 7 Alternatives to Google Earth

    Google Earth has received so much press coverage that many users will appreciate that it is one of the coolest applications to download. In brief, it is a feature-laden 3D virtual globe, map and geography browser which lets users zoom in on their world with fantastic detail. View satellite imagery, maps, terrain, 3D buildings and even explore galaxies in the sky. This application allows the exploration of rich geographical content, save toured places and share with others. The software maps the earth by the superimposition of images obtained from satellite imagery, aerial photography and GIS 3D globe. Google Earth is undoubtedly a very impressive application, and it is extremely hard not to admire the wealth of features that it offers. Its satellite images are unrivaled, it provides useful and accurate statistical information, and the software has many practical benefits, such as helping to find locations and give driving directions. In terms of functionality, this application earns our highest praise. We use the software on a regular basis on both desktop and mobile devices (the latter under Android). However, while Google Earth is available to download without charge, Google do not release the software under an open source license. In the past there have been attempts to reverse engineer Google Earth and implement its features in an open and extensible way. However, these actions were understandably frowned upon by Google. Instead we prefer to see the development of open source virtual globe software which uses freely licensed or public domain data. While the development of open source virtual globe applications may not, in itself, encourage Google to release its application or data under a similar license, it does give users the option to be able to have the freedom to do what they want. This route also helps to foster greater user community support to drive development often in the form of add-ons and plug-ins. There are a number of applications which are credible open source alternatives to Google Earth. While none of the software applications featured in this article have all of the features offered by Google Earth (although some offer some different features), and they are not exactly comparable, they are all worthy of investigating.

  • Warzone 2100 Lands Vulkan Renderer, Adaptive V-Sync For 20+ Year Old Game

    Warzone 2100 as the real-time strategy/tactics game that first premiered in 1999 before becoming open-source in 2004 and then fully open-source with game data in 2008 is now evolving in 2020 with Vulkan graphics support. The open-source Warzone 2100 game not only has a Vulkan back-end that was merged today but also OpenGL ES 2.0/3.0 support for those wanting to relive this late 90's computer game on mobile/embedded devices having only GLES drivers.

  • [NetBSD] Curses Library Automated Testing

    My GSoC project under NetBSD involves the development of the test framework of curses. This is the final blog report in a series of blog reports; you can look at the first report and second report of the series. The first report gives a brief introduction of the project and some insights into the curses testframe through its architecture and language. To someone who wants to contribute to the test suite, this blog can act as the quick guide of how things work internally. Meanwhile, the second report discusses some of the concepts that were quite challenging for me to understand. I wanted to share them with those who may face such a challenge. Both of these reports also cover the progress made in various phases of the Summer of Code. This being the final report in the series, I would love to share my experience throughout the project. I would be sharing some of the learning as well as caveats that I faced in the project.

  • [NetBSD] RumpKernel Syscall Fuzzing

    The first and second coding period was entirely dedicated to fuzzing rumpkernel syscalls using hongfuzz. Initially a dumb fuzzer was developed to start fuzzing but it soon reached its limits. For the duration of second coding peroid we concentrated on crash reproduction and adding grammar to the fuzzer which yielded in better results as we tested on a bug in ioctl with grammar. Although this works for now crash reproduction needs to be improved to generate a working c reproducer. For the last coding period I have looked into the internals of syzkaller to understand how it pregenerates input and how it mutates data. I have continued to work on integrating buildrump.sh with build.sh. buildrump eases the task fo building the rumpkernel on any host for any target. buildrump.sh is like a wrapper around build.sh to build the tools and rumpkernel from the source relevant to rumpkernel. So I worked to get buildrump.sh working with netbsd-src. Building the toolchain was successfull from netbsd-src. So binaries like rumpmake work just fine to continue building the rumpkernel.

  • Bandwidth for Video Conferencing

    For the Linux Users of Victoria (LUV) I’ve run video conferences on Jitsi and BBB (see my previous post about BBB vs Jitsi [1]). One issue with video conferences is the bandwidth requirements. The place I’m hosting my video conference server has a NBN link with allegedly 40Mb/s transmission speed and 100Mb/s reception speed. My tests show that it can transmit at about 37Mb/s and receive at speeds significantly higher than that but also quite a bit lower than 100Mb/s (around 60 or 70Mb/s). For a video conference server you have a small number of sources of video and audio and a larger number of targets as usually most people will have their microphones muted and video cameras turned off. This means that the transmission speed is the bottleneck. In every test the reception speed was well below half the transmission speed, so the tests confirmed my expectation that transmission was the only bottleneck, but the reception speed was higher than I had expected. When we tested bandwidth use the maximum upload speed we saw was about 4MB/s (32Mb/s) with 8+ video cameras and maybe 20 people seeing some of the video (with a bit of lag). We used 3.5MB/s (28Mb/s) when we only had 6 cameras which seemed to be the maximum for good performance.

  • Lack of Qualified Linux Talent Impedes Enterprise Move to the Clouds

    The Linux Foundation has been working to address the shortage of Linux talent for many years with a combination of training and certification exams. Despite this, the breathtaking growth in Linux adoption, especially as the de facto OS of the cloud, means that there is still a shortage of qualified talent, according to Clyde Seepersad, senior vice president and general manager for training and certification at The Linux Foundation (LF). “We are always supportive of developments in the training ecosystem which help address this gap. In particular, we are finding that demand for our performance-based certification exams continues to be gated by individuals not feeling adequately prepared,” he told LinuxInsider. LF’s certification exams include Certified Kubernetes Administrator, Certified Kubernetes Application Developer, Linux Foundation Certified SysAdmin, and Linux Foundation Certified Engineer. “ACG and LA both have excellent reputations for the quality of their open-source training content so we are pleased to see them come together to better serve the talent development needs of the open-source software ecosystem,” he added.

  • Last phase of the desktop wars?

    Economic pressure will be on Microsoft to deprecate the emulation layer. Partly because it’s entirely a cost center. Partly because they want to reduce the complexity cost of running Azure. Every increment of Windows/Linux convergence helps with that – reduces administration and the expected volume of support traffic. Eventually, Microsoft announces upcoming end-of-life on the Windows emulation. The OS itself , and its userland tools, has for some time already been Linux underneath a carefully preserved old-Windows UI. Third-party software providers stop shipping Windows binaries in favor of ELF binaries with a pure Linux API… …and Linux finally wins the desktop wars, not by displacing Windows but by co-opting it. Perhaps this is always how it had to be.
