  • Green Hills Software Adds Industry-Leading Advanced Software Development Tools Support for RISC-V
  • Sonoff SNZB Zigbee Sensors and Switches Launched for under $10

    All four devices are powered by a CR2450 coin cell battery and you’ll get a notification once the battery level drops below 10% in the mobile app. Which mobile? The usual eWelink app for Android or iOS which also supports integration with IFTTT. If you prefer open-source firmware, it may take more time, or never happen, as while we’ve reported on Zigbee open-source firmware, most of the work is based on TI CC25xx chips, and Sonoff Zigbee sensors are all likely based on Silicon Labs EFM32 Zigbee MCU like it is for their ZBBrigde gateway.

  • openSUSE + LibreOffice Conference Will Take Place Online

    Organizers of the openSUSE + LibreOffice Conference along with the project’s boards have made the decision to change the conference to an online conference.

    The uncertainty surrounding the COVID-19 pandemic and its effect on travel, conference planning, logistics and possibility for attendees to come to the event were reasons for shifting the event from a physical event to an online event.

    Shifting the conference online is good news and the organizers intend to provide a great conference that is filled with insightful talks, technical presentations and sessions dedicated for those who want to socialize during the event. Using video a conferencing tool, attendees learn about new technologies in openSUSE and LibreOffice and have the chance to chat to developers and ask questions. Communities involved in marketing, design, QA and other topics will be able to meet online, catch up and exchange ideas.

    Back in February, Sony unveiled their “Mark 2” lineup, i.e. the flagship Xperia 1 II and the mid-range Xperia 10 II smartphones via an online event. Months after the initial announcement, the phones are now available for pre-order across Europe as well as in the US. On the software side, both of these devices run Android 10 out of the box. To satisfy the requirements of the GNU General Public License v2 and kickstart the custom development of third-party ROMs and kernels, Sony has now released the kernel sources for the Xperia 10 II and the Xperia 1 II.

  • MicroK8s now native on Windows and macOS

    Windows and macOS developers can now use MicroK8s natively! Use kubectl at the Windows or Mac command line to interact with MicroK8s locally just as you would on Linux. Clean integration into the desktop means better workflows to dev, build and test your containerised apps.

    MicroK8s is a conformant upstream Kubernetes, packaged for simplicity and resilience. It provides sensible defaults and bundles the most commonly used components for at-your-fingertips access. A single-node install is one command and done in seconds, which makes it easy to add or remove from any system.

    MicroK8s is widely used by developers for local testing. After installing it, you can start and stop Kubernetes with a single command to conserve battery. With built-in GPGPU acceleration, Istio, Prometheus, Jaeger and many other popular services on tap, it serves as a complete workstation edition of K8s. All of this capability is now neatly accessible from the Windows and macOS command-line.

    Welcome to the Ubuntu Weekly Newsletter, Issue 633 for the week of May 24 – 30, 2020.

  • Retrotech: The Novell NetWare Experience

    In the simplest terms possible, NetWare was a dedicated network operating system. It was designed around fast and reliable network operations at the expense of almost everything else. Novell had invested massive amounts of research in figuring out how to do fast I/O and minimizing any delays from hardware related sources. The end result was a very lean system that remained stable and performant with a large number of clients attached. As networking was Novell's bread and butter, NetWare had excellent support for everything: clients were available for DOS, Windows, UNIX, Macintosh, OS/2 and probably other platforms I've never even heard of.

    The early history of NetWare is very muddled, and pre-2.0 versions have been lost to time. This compounded with poor documentation has made it very difficult to trace the early history of the product. However, while NetWare was not the first (or only) network product for IBM PCs, it quickly became the largest, displacing IBM's PC Network, and laughed at Microsoft's LAN Manager, and IBM OS/2 LAN Server.

    While NetWare did compete on UNIX, Sun had already gotten their foot in the door by porting NFS and making it the de-facto solution for all UNIXs of the era, as well as Linux. Meanwhile, Apple held onto AppleTalk which itself survived well into the early 2000s when NetWare had already disappeared into the aether. The explosion of Wintel PCs throughout the 90s had given NetWare a market position that should have been very difficult to dislodge.

    The full story of NetWare's fall from grace is a story for another time, but I do want to go into the more technical aspects that were both the boon and bane of NetWare. Much of NetWare's success can be attributed to its own IPX protocol which made networking plug and play and drastically lowered latencies compared to NetBIOS or even TCP/IP.

  • 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.
