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.

Review: Red Hat Enterprise Linux 8.0

My experiment with RHEL 8 got off to a rough start. Going through the on-line registration process produced some errors and ended up with me getting the wrong ISO which, in turn, resulted in some confusion and delays in getting the distribution installed. Things then began to look up as RHEL 8 did a good job of detecting my system's hardware, registered itself without incident and offered good performance on physical hardware. I was particularly pleased that the distribution appears to detect whether our video card will work well with Wayland and either displays or hides Wayland sessions in response. I did have some trouble with the GNOME Classic Wayland session and GNOME Shell on X.Org was a bit sluggish. However, the Classic session on X.Org and GNOME Shell on Wayland both worked very well. In short, it's worthwhile to explore each of the four desktop options to see what works best for the individual. The big issues I ran into with RHEL were with regards to software management. Both GNOME Software and the Cockpit screen for managing applications failed to work at all, whether run as root or a regular user. When using the command line dnf package manager, the utility failed to perform searches unless run with sudo and occasionally crashed. In a similar vein, the Bash feature that checks for matching packages when the user types a command name it doesn't recognize does not work and produces a lengthy error. There were some security features or design choices that I think will mostly appeal to enterprise users, but are less favourable in home or small office environments. Allowing remote root logins by default on the Workstation role rubs me the wrong way, though I realize it is often useful when setting up servers. The enforced complex passwords are similarly better suited to offices than home users. One feature which I think most people will enjoy is SELinux which offers an extra layer of security, thought I wish the Cockpit feature to toggle SELinux had worked to make trouble-shooting easier. I was not surprised that RHEL avoids shipping some media codecs. The company has always been cautious in this regard. I had hoped that trying to find and install the codecs would have provided links to purchase the add-ons or connect us with a Red Hat-supplied repository. Instead we are redirected through a chain of Fedora documentation until we come to a third-party website which currently does not offer the desired packages. Ultimately, while RHEL does some things well, such as hardware support, desktop performance, and providing stable (if conservative) versions of applications, I found my trial highly frustrating. Many features simply do not work, or crash, or use a lot of resources, or need to be worked around to make RHEL function as a workstation distribution. Some people may correctly point out RHEL is mostly targeting servers rather than workstations, but there too there are a number of problems. Performance and stability are provided, but the issues I ran into with Cockpit, permission concerns, and command line package management are all hurdles for me when trying to run RHEL in a server role. I find myself looking forward to the launch of CentOS 8 (which will probably arrive later this year), as CentOS 8 uses the same source code as RHEL, but is not tied to the same subscription model and package repositories. I am curious to see how much of a practical effect this has on the free, community version of the same software. Read more

GNOME 3.34 Revamps the Wallpaper Picker (And Fixes a Longstanding Issue Too)

The upcoming release of GNOME 3.34 will finally solve a long standing deficiency in the desktop’s background wallpaper management. Now, I’ve written about various quirks in GNOME wallpaper handling before, but it’s the lack of option to pick a random wallpaper from a random directory via the Settings > Background panel that is, by far, my biggest bug bear. Ubuntu 19.04 ships with GNOME 3.32. Here, the only wallpapers available to select via the Settings > Background section are those the system ships with and any top-level images placed in ~/Pictures — nothing else is selectable. So, to set a random image as a wallpaper in GNOME 3.32 I tend to ignore the background settings panel altogether and instead use the image viewer’s File > Set as background… option (or the similar Nautilus right-click setting). Thankfully, not for much longer! Read more
