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.

Zapcc Liberated, HMM and GPL

  • Zapcc high-speed C++ compiler now open source
    Zapcc, a caching C++ compiler built for speed, has gone open source. Ceemple Software, Zapcc’s builder, claims the compiler offers dramatic improvements in both incremental and full builds compared to building with Clang 4.0 and Clang 5.0. Based on heavily modified code from the Clang compiler project, Zapcc uses an in-memory compilation cache in a client-server architecture. All compilation information is remembered between runs.
  • Heterogeneous memory management meets EXPORT_SYMBOL_GPL()
    One of the many longstanding — though unwritten — rules of kernel development is that infrastructure is not merged until at least one user for that infrastructure exists. That helps developers evaluate potential interfaces and be sure that the proposed addition is truly needed. A big exception to this rule was made when the heterogeneous memory management (HMM) code was merged, though. One of the reasons for the lack of users in this case turns out to be that many of the use cases are proprietary; that has led to some disagreements over the GPL-only status of an exported kernel symbol. The HMM subsystem exists to support peripherals that have direct access to system memory through their own memory-management units. It allows the ownership of ranges of memory to be passed back and forth and notifies peripherals of changes in memory mappings to keep everything working well together. HMM is not a small or simple subsystem, and bringing it into the kernel has forced a number of low-level memory-management changes. After a multi-year development process, the core HMM code was merged for the 4.14 kernel, despite the lack of any users.

Software: elementary OS Software, Unified Modeling Language (UML), PulseAudio 12.0 and Zstd

  • An Awesome List of Apps & Resources for elementary OS
    It is barely up to a day since I put up a positive review of elementary OS which is well deserved because it has come a long way from what it was 2 years ago when FossMint checked it out. The good news I’ve got for you today is that the developers have published a page on GitHub that contains “curated list of awesome applications, tools and shiny things for elementary OS”. They are grouped into categories for easy selection, are all open source, and clicking on the green tick icons will direct you to the app on elementary OS’s AppCenter.
  • Best Free Unified Modeling Language Tools
    Unified Modeling Language (UML) is a general-purpose, modeling language designed to provide a standard way for visualizing, specifying, constructing, and documenting the artifacts of distributed object systems. It’s the industry standard modeling language for software engineering. The aim of UML is to give software engineers, agile and small development teams, and system architects useful tools for analysis, design, and implementation of software-based systems. It also provides modeling business and similar processes. The language helps to visualize your object-oriented design and communicate with others. It offers limited use for other programming paradigms.
  • PulseAudio 12.0 release notes
    When playing videos, it's important that the audio latency is known so that the video can be synchronized accurately. PulseAudio doesn't get good latency information from the kernel with A2DP playback, which has caused A/V sync problems for many people when watching videos. Now PulseAudio makes the audio buffer in the kernel much smaller, which reduces the problem a lot.

  • Zstandard – A Super Faster Data Compression Tool For Linux
    This is known topic and we were using in our day to day activity to compress and decompress files & folders. You might already know zip,tar,7-zip, etc and you would have used all these application for your requirement. Even today also we are going to discuss about similar kind of topic, the tool name is Zstandard. It is super fast data compression tool and compression ratio is very very low. Zstd is lossless data compression algorithm developed by Yann Collet at Facebook. Due to high data compression ratio many of the popular companies and databases are using this tool.

KDE: CMake 3.12 With FreeBSD, Krita 4.1 Beta, C++/Qt

  • CMake 3.12 Update on FreeBSD
    CMake 3.12 has reached rc1. That means we’re testing the update on FreeBSD, and building lots and lots of packages. And, as I’ve written previously, every CMake update triggers a bunch of interesting software findings. As a motto, I’ve got “use it, aggressively improve it” on my website (you can hire me for odd CMake and C++ jobs, too). So hitting compile issues makes me turn to fixing software outside of KDE.

  • The day Kate Gregory enjoyed Qt
    At my company we use C++ for everything, from creating microservices to website backends and as a generator for website frontends, I mean, we do a lot of c++. And because of that we always need more c++ people, but sometimes it’s hard to find developers, but it’s easy to find php / python / javascript ones. Because of that we hired Kate Gregory’s famous c++ course – “Teaching the Teacher” to train current C++ developers to teach C++. (now, that’s a lot of ‘C++’ in a simple sentence, I know. bear with me.) For those that doens’t know, Kate Gregory is somebody that uses, advocates our beloved language even before I was born, and talks all over the world about C++ and also do trainings for companies, And so I enlisted to be her student. It was a really pleasant course going thru how to proplery explain C++ for people that know how to program but don’t know how to C++, and for that I’m grateful. But then when I commented out about Qt in the middle of the class she rolled her eyes, that made me feel a bit uneasy so I talked to her on why the eye-roll. “Qt is not c++”, and I tougth this was already settled down for years, so I asked her if she would be open to see some simple c++ code written in Qt and tell me what she thinks of it. “Well, Yes. but people already tried and it was not good”.

Red Hat: Kubernetes, 'Cloud', and GlusterFS 4.1.0 Release

  • Kubernetes StatefulSet In Action
    Recently, I stumbled upon a StackOverflow question around StatefulSets which made me wonder how well understood they are at large. So I decided to put together a simple stateful app that can be used to experiment with a StatefulSet. In this blog post we will have a closer look at this app and see it in action. If you’re not familiar with StatefulSets, now is a good time for a refresher, consulting the official docs concerning their usage and guarantees they provide.
  • The road to cloud-native applications
    As many organizations do not have the luxury of completely rebuilding their technology foundation or immediately adopting new practices and mindsets, they can embrace gradual yet fundamental shifts in culture, processes, and technology to help support greater velocity and agility. With software increasingly key to how users engage with businesses and how businesses can innovate to stay competitive, organizations should adapt to the new demands of the Digital Economy, such as speeding up application development and delivery. The cloud-native approach describes a way of modernizing existing applications and building new applications based on cloud principles, using services and adopting processes optimized for the agility and automation of cloud computing.
