  • Build a printer UI for Raspberry Pi with XML and Java | Opensource.com

    Creating a GUI from scratch is a very time consuming process, dealing with all the positions and alignments in hard code can be really tough for some programmers. In this article, I demonstrate how to speed up this process using XML.
    This project uses TotalCross as the target framework. TotalCross is an open source, cross-platform software development kit (SDK) developed to create GUIs for embedded devices faster. TotalCross provides Java's development benefits without needing to run Java on a device because it uses its own bytecode and virtual machine (TC bytecode and TCVM) for performance enhancement.

    I also use Knowcode-XML, an open source XML parser for the TotalCross framework, which converts XML files into TotalCross components.

  • How to Use Tails Linux OS in VirtualBox Virtual Machine - Linux Shout

    Well, Debian-based Tails is not the Linux system that we can install on our PC like Windows or other Linux distros. Instead, it is a hardened Linux system meant to run in a Live environment via DVD or USB stick. So it offers extensive security. Here we learn the steps to set up, run and use Tails in VirtualBox Virtual Machine to learn and get familiar with it.

    The Tails Linux distribution is designed as a live system particular for data protection and anonymity on the Internet. We can easily write in on a USB drive using software such as Rufus or Etcher; or else burn it on a DVD. This makes it a portable Linux OS that a user can use on any system without leaving a trace behind or storing any data on the computer’s hard drive.

  • Installing latest syslog-ng on openSUSE, RHEL and other RPM distributions

    The syslog-ng application is included in all major Linux distributions, and you can usually install syslog-ng from the official repositories. If the core functionality of syslog-ng meets your needs, use the package in your distribution repository (yum install syslog-ng), and you can stop reading here. However, if you want to use the features of newer syslog-ng versions (for example, sending log messages to Elasticsearch or Apache Kafka), you have to either compile syslog-ng from source, or install it from unofficial repositories. This post explains you how to do that.

  • 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.
