  • Quarking Drools: How we turned a 13-year-old Java project into a first-class serverless component

    Rule-based artificial intelligence (AI) is often overlooked, possibly because people think it’s only useful in heavyweight enterprise software products. However, that’s not necessarily true. Simply put, a rule engine is just a piece of software that allows you to separate domain and business-specific constraint from the main application flow. We are part of the team developing and maintaining Drools—the world’s most popular open source rule engine and part of Red Hat—and, in this article, we will describe how we are changing Drools to make it part of the cloud and serverless revolution.

  • Why feedback, not metrics, is critical to DevOps

    Most managers and agile coaches depend on metrics over feedback from their teams, users, and even customers. In fact, quite a few use feedback and metrics synonymously, where they present feedback from teams or customers as a bunch of numbers or a graphical representation of those numbers. This is not only unfortunate, but it can be misleading as it presents only part of the story and not the entire truth.

  • L2TP Tunnel Support Added To Systemd

    The newest feature addition for systemd is supporting L2TP, the Layer 2 Tunneling Protocol, as part of its networking code. 

    Systemd's networkd now has support merged for LT2TP tunnel support. L2TP can be used for extending a local area network (LAN) or also for VPN purposes when paired with the likes of IPsec for providing encryption. L2TP also has a variety of other use-cases with this bare protocol able to offer a layer two link over an L3 network.

  • libinput 1.12.901
    The first RC for libinput 1.13 is now available.
    
    
    
    
    Only two notable features in this release but patches are accumulating on
    master, it's been 6 months since 1.12 and I've decided to postpone the two
    major features (hi-res scrolling and totem support) to 1.14.
    
    
    
    
    Touch arbitration has improved for tablets, especially on touch screens.
    A timer set on pen proximity out means we don't get ghost touches anymore
    when the hand lifts off slower than the pen itself. And location-based touch
    arbitration means that parts of the screen can be interacted with even while
    the pen is in proximity. libinput uses the tilt information where
    available to disable touches in a rectangle around the pen where the hand is
    likely to be but leaves the rest of the touchscreen available otherwise.
    Where the UI supports it, this allows for bimanual interaction.
    
    
    
    
    The test suite is installed on demand (meson -Dinstall-tests=true). Where
    run from the installed location it will use the normal library lookups and
    the quirks directory as defined by the prefix. This makes it useful for
    distribution-level testing, i.e. run this on a test machine after updating
    the package to make sure everything is as expected. Where available, you can
    invoke it with the "libinput test-suite" command.
    
    
    
    
    Other than that, a load of fixes, quirks added, cleanups, tidy-ups and so on
    an so forth.
    
    
    
    
    As usual, the git shortlog is below. Many thanks to all the contributors.
  • Libinput 1.13 Is Coming But High-Resolution Scrolling & Dell Totem Support Delayed

    Libinput is fairly mature at this stage for offering a unified input handling library for use on both X.Org and Wayland Linux desktops. Libinput has largely reached a feature plateau with new releases no longer coming out so often and no glaring gaps in support. With it already being a half-year since the last major release, libinput 1.13 is now being buttoned up for release and available today is the first release candidate. 

    Libinput 1.13 isn't that exciting of a release particularly since maintainer Peter Hutterer of Red Hat decided to delay the high resolution scrolling support. The Linux 5.0 kernel brought the much anticipated high resolution scrolling support for various Logitech/Microsoft mice to improve the scroll-wheel experience. Besides the kernel support, there is also the user-space support that needs updating. Peter decided to delay this functionality now until Libinput 1.14 to give it more time to bake.

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.
