  • Noodlings | KDE Plasma 5.19, Partition Manager and a BADaptor

    KDE Plasma 5.19 Experience

    It is another fantastic release with much attention being made to the finer details that enhance the usability experience without taking away from any of its functionality.

    KDE Partition Manager

    I have become quite the fan of Gparted over the years of my Linux life and I started wondering if there were other partition management options out there. Specifically one that is Qt based instead. This is not a light on GTK based applications, I just find that they don’t tend to look as nice and clean as Qt apps. In this off-hand search, I stumbled upon PartitionManger which is in official openSUSE Tumbleweed and Leap Repositories.

    I have reached the end of the road with this machine. We have been together for about three years and before sending it off to the ether, I wanted to try out openSUSE Tumbleweed on it. It was something of a question I have been asking myself since I was first assigned the piece of hardware. Windows 7 worked fine on it but how would it spin with the Plasma desktop.

  • Modern development - SUSE CTO: This is not a test, this is real testing

    Hold on now, this isn’t going to hurt. But in case your chest just contracted a bit – relax. I am not intending to use you as Guinea pigs fed with semi-random code de jour to test you. That being said… I am going to test, test, test your ability to embrace testing, because testing is never overrated. In fact, you hardly can test too much.

    The question is “when” and “how” and “what” you test.

    It’s long been a common understanding that the earlier you catch an issue, the less effort there is involved to address it… and the cheaper it is to fix. Not to mention the fact that you will upset fewer colleagues (or indeed users!) in the process of calming them down and showing that code has been remediated. So, in general, ‘the earlier, the better’ should be our mantra here.

    CI/CD/CD (or Continuous Integration/Continuous Delivery/Continuous Deployment) are common buzzwords these days, alongside DevOps. These are about a tight, virtuous cycle of developing in small increments and high frequency, integrating those changes and making the result available (Delivery) and rolling them out (Deployment).

    While technically not a strict requirement, the success or failure of a CI/CD approach closely hinges on testing being part of the integration phase, beyond merely building the software.

  • Taking a practical approach to open source PostgreSQL

    The open source PostgreSQL database, sometimes referred to as Postgres, is continuing to find new applications as a scalable relational database.

    At the Postgres Vision 2020 virtual conference, held Tuesday and Wednesday, database developers and users shared insights on PostgreSQL's past, present and future. The event was sponsored by EnterpriseDB, which used the event to mark its rebranding to EDB.

    PostgreSQL is an open source database and can be freely used by anyone. EDB provides a commercial distribution as well as different support options for those running the community edition of PostgreSQL on their own.

  • Meet the Groundswell of Open Source COVID-19 Efforts

    As the global pandemic continues, the number of open source COVID-19 software and hardware projects – developed by diverse open source communities – continues to grow.

  • Intel oneAPI DPC++ Compiler 2020-06 Released With New Features

    While Intel has been providing daily snapshots of the oneAPI Data Parallel C++ (DPC++) open-source compiler, today marks the latest monthly feature compiler release to their cross-architecture language for direct programming that is based on C++ while leveraging SYCL, LLVM/Clang, and other open-source technologies for exploiting the potential of hardware from CPUs to GPUs and FPGAs.

    The Intel oneAPI DPC++ Compiler release for June 2020 brings some notable new features. The DPC++ Compiler 2020-06 release has partial support for host task with interop capabilities for better SYCL-OpenCL interoperability. There is also a new Level Zero plug-in for enabling SYCL on top of the Intel oneAPI Level Zero API but the interoperability support is not yet complete. Various new extensions have also been wired up like SYCL_INTEL_bitcast, parallel_for simplification, SYCL_INTEL_enqueue_barrier, SYCL_INTEL_accessor_simplification, and 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.
