  • Episode 49 | This Week in Linux

    On this episode of This Week in Linux, there’s a brand new release of the Linux Kernel with 4.20. The EU is offering Bug Bounties for Open Source software and MIPS has announced it’s going to become Open Source. We’ll have a follow up to the Necuno Mobile topic from Episode 45 and then we’ll take a look at some Distro News for Septor Linux, OviOS and One Laptop Per Child. Then we’ll cover some App News from Syncthing, Mixxx, Darktable, RawTherapee, KStars, and much more. Later in the show, we’ll talk about some Linux Gaming news. All that and much more!

  • Gergely Nagy: One hat less

    At the time, I was... a different person. I was full of myself at times, I was angry, perhaps a tad too elitist at times too. I'm not proud of old me, but it's part of me. I grew, and became a better person, there's no shame in being able to grow - quite the contrary. And Debian helped immensely. I've had role models in the project, who I look up to even to this day, who helped shape me one way or the other.

    There are two people I need to mention specifically: Martin Michlmayr and Rhonda D'Vine.

    Martin was my Application Manager when I applied, I considered him a mentor, a friend. The example he set were instrumental in shaping me too. Rhonda helped me get to my first ever conference: I got on a train to Vienna, and she took me to LinuxTag in her car from there, and then back again. That first LinuxTag, the path that led there, the conference itself, was formative, and both Martin and Rhonda had a big part in it being so. Thank you again - so many years later, I still smile when I think back. Those years we were in touch, meant a lot to me.

  • Speeding up Open vSwitch with partial hardware offloading

    Open vSwitch (OVS) can use the kernel datapath or the userspace datapath. There are interesting developments in the kernel datapath using hardware offloading through the TC Flower packet classifier, but in this article, the focus will be on the userspace datapath accelerated with the Data Plane Development Kit (DPDK) and its new feature—partial flow hardware offloading—to accelerate the virtual switch even more.

    This article explains how the virtual switch worked before versus now and why the new feature can potentially save resources while improving the packet processing rate.

  • Alibaba invests in open source tech with data Artisans

    Chinese e-commerce giant Alibaba Group has acquired German startup data Artisans (dA) to build an initiative around Big Data open source technologies.

    The move is also aimed at developing stream processing, batch processing and machine learning for developers to leverage in areas like artificial intelligence, Internet of Things and other real-time processing applications.

    As per local media reports, the deal has been valued at EUR 90 million. While both firms issued official statements, the details of the deal were not disclosed.

  • Next C++ workshop: 10 January 2019 at 19:00 UTC

    Yes, we’re running another C++ workshop, where you can watch a video about a specific feature of the language, then join our community of developers for a live discussion!

  • UK is testing self-driving Mars rovers

    Despite the fact that landing on Mars is hard, robotic rovers and landers have now become a regular feature of Mars exploration. These advanced exploratory machines are sending back unprecedented information about this fascinating red world. One limitation, however, has been that rovers and landers are still, for the most part, controlled by human operators back on Earth. On January 2, 2019, the U.K. government announced the testing of new software that’ll help make future rovers more autonomous – “smarter” and more capable of making their own decisions, such as deciding where to go and how to get there – i.e. self-driving.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
