  • Fedora Magazine - Quarkus and Mutiny

    Quarkus is a foundation for building Java based applications; whether for the desktop, server or cloud. An excellent write up on usage can be found at https://fedoramagazine.org/using-the-quarkus-framework-on-fedora-silverblue-just-a-quick-look/. This article is primer for coding asynchronous processes using Quarkus and Mutiny.

    So what is Mutiny? Mutiny allows streaming of objects in an event driven flow. The stream might originate from a local process or something remote like a database. Mutiny streaming is accomplished by either a Uni or a Multi object. We are using the Uni to stream one object — a List containing many integers. A subscribe pattern initiates the stream.

    A traditional program is executed and results are returned before continuing. Mutiny can easily support non-blocking code to run processes concurrently. RxJava, ReactiveX and even native Java are alternatives. Mutiny is easy to use (the exposed API is minimal) and it is the default in many of the Quarkus extensions. The two extensions used are quarkus-mutiny and quarkus-vertx. Vert.x is the underlying framework wrapped by Quarkus. The Promise classes are supplied by quarkus-vertx. A promise returns a Uni stream when the process is complete. To get started, install a Java JDK and Maven.

  • How to Connect Wi-Fi using Nmcli in Linux

    Why use the Network-command-line Manager’s interface? Sometimes Ubuntu Network Manager behaves strangely, and you may be unable to connect to any Wi-Fi Hotspot using the GUI (Graphical user interface). The Network Manager may fail to start, and even after manually restarting the service through the terminal, you may still have difficulties connecting to any Wi-Fi Hotspot, even a previously recognized and stored home network. I encountered same problem on dual boot configurations and standalone Linux installs, and it was quite inconvenient, particularly during the WFH (Work from home) phase that we’re all going through.

  • How to Add Comments to UFW Rules

    In an earlier article we discussed how to add comments to iptables rules for clarity and documentation. In our opinion it is a good practice to comment anything someone else may have to work on in the future. Using comments in scripting is a common practice for good reason. We decided to write a quick tip on how to add a comment to UFW (Uncomplicated Firewall) rules. I am not a huge fan of UFW or Firewalld. In my opinion they make managing netfilter harder, not easier. That is because I started using iptables over 20 years ago. I am very comfortable with it and tend to know the necessary syntax off the top of my head. That being said, adding a comment to UFW rules is much more intuitive than any other iptables front end.

GNOME and KDE: This Week in GNOME, Qt6 and KF6

  • #44 Five Across · This Week in GNOME

    Update on what happened across the GNOME project in the week from May 13 to May 20.

  • Okteta making a small step to Qt6 | Attracted by virtual constructs

    Old, but stable, even more in when it comes to the feature set, and still getting its polishing now and then: your simple editor for the raw data of files, named Okteta. What started in 2003 as a hex editing widget library for KDE3 (and Qt3), of course named KHexEdit (to be confused with the unrelated hex editor program that was part of KDE at that time), it turned into a first dedicated application by the title Okteta during the years 2006 to 2008 for KDE4 (and Qt4). From there on a small set of features was added once in a while, most impressively Alexander Richardson’s Structures tool in 2010,. Until then in 2013 the port to Qt5/KF5 was done (also to a good degree by Alexander). After that things had settled, the program working properly when needed, otherwise just left in the corner of the storage. Now, nearly 2 decades after the first lines were written, the next port is to be done, to Qt6 and KF6. And this time the actual port is just amazingly boring: changing a few “Qt5” to “Qt6” in the buildsystem (and later some “KF5” to “KF6” once KF6 is ready), adding Qt6::Core5Compat as helper library for 1-2 classes that had not yet been substituted, adding a “const” to the argument of an overridden virtual method, adapting some “QStringList” forward declarations… and done.

The 5 best Application Launchers for Ubuntu

Every operating system comes with an application launcher where you have to mouse over the entire menu to launch an application. But, unlike other operating systems, Linux allows us to install other launchers as an alternative. In this post, We came up with the five best application launchers for Ubuntu and their installation process. Ubuntu has a default application launcher, i.e., GNOME Shell application overview. If you are a beginner or a tech professional, browsing the entire menu to launch an application is quite bothersome. Linux community offers a wide variety of application launchers.

Choosing the right application launcher as per your need might be difficult. That’s why we came up with the five best application launchers. Here are the top 5 application launchers for your Ubuntu.
