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.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think). In a blog post by Christian Fredrik Schaller (Director for Desktop/Graphics, Red Hat), he mentions that they are making serious efforts to improve accessibility. Starting with Red Hat hiring Lukas Tyrychtr, who is a blind software engineer to lead the effort in improving Red Hat Enterprise Linux, and Fedora Workstation in terms of accessibility. Read more
