  • 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.

  • The Top 5 Linux Courses for Developers, Cloud Engineers, and DevOps in 2021

    The world of technology is booming, and there is plenty to learn, especially for developers, cloud engineers, and devops. Add Linux to this list, and you will never fall short of options. There are a series of courses to choose from, all of which can be undertaken from the comfort of your home.

    Choose from a variety of options like Udemy, Coursera, and Pluralsight, amongst others. The best part: some of them even provide you a completion certificate, which you can publish on your LinkedIn profile, and even on your resume.

    Here are some of the best online Linux courses.

  • 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.

  • What is Raspberry Pi 4 “Model B”? [Ed: I'm still waiting for them to formally apologise for going behind customers' backs, making secret deals with Microsoft to put Microsoft malware on all those devices]

    Raspberry Pi has conquered the world of SoC (System on a Chip). It has already garnered millions of followers since its release in 2012. Not only is it inexpensive, but it’s also versatile, modular, and multi-purpose. It has become popular not only as a credit-sized computer board but also as a controller in electronic, robotics, and IoT projects. The size, features, and price drive the popularity of the Pi, especially in the DIY community. To keep up with the current technological trends, the tiny board has undergone plenty of upgrades over the years, and there have been many varieties so it can cater to the needs and demands of its users. In 2019, the Raspberry Pi Foundation released the fourth generation of the multi-purpose board, the Raspberry Pi 4 B. It is the most powerful Pi to date, sporting huge upgrades from its predecessors. The compact board is touted to deliver a PC-level performance, and it didn’t disappoint.

  • Kentaro Hayashi: Grow your ideas for Debian Project

    There may be some "If it could be ..." ideas for Debian Project. If idea is concreate and worth to make things forward, it should make a proposal for Project Funding. [...] I'm not confident whether mechanism works, but Debian needs change.

  • Sam Thursfield: Calliope, slowly building steam

    There are some interesting complexities to this, and in 12 hours of hacking I didn’t solve them all. Firstly, Bandcamp artist and album names are not normalized. Some artist names have spurious “The”, some album names have “(EP)” or “(single)” appended, so they don’t match your tags. These details are of interest only to librarians, but how can software tell the difference? The simplest approach is use Musicbrainz, specifically cpe musicbrainz resolve-ids. By comparing ids where possible we get mostly good results. There are many albums not on Musicbrainz, though, which for now turn up as false positives. Resolving Musicbrainz IDs is a tricky process, too — how do we distinguish Multi-Love (album) from Multi-Love (single) if we only have an album name? If you want to try it out, great! It’s still aimed at hackers — you’ll have to install from source with Meson and probably fix some bugs along the way. Please share the fixes!

  • Neovide Is A Graphical Neovim Client Written In Rust

    Neovide is a really cool GUI client for Neovim. Although it essentially functions like Neovim in the terminal, Neovide does add some nice graphical improvements such as cursor animations and smooth scrolling. It even has me thinking about making it my new "vim" alias.

Get involved with Mageia, become a Packager

With Mageia 8 just released and development for Mageia 9 getting underway in Cauldron, the unstable branch of Mageia, now is a great time to get involved with packaging. We are starting to look at the features that we want to include for Mageia 9, and as it is so early in the development cycle, now is the time for major developments, or big updates to key pieces of software. This is a great time to join the project as you can propose features you would like to see, help to implement large changes or see how a distribution evolves through development, stabilisation and then is released. If there is an application that you are interested in, if you want to help maintain part of the distribution, or if you want to learn something new, there are many opportunities to do so with the packaging team.

Google does not want you to tell your players about your donation page

I recently updated Pixel Wheels banner image on Google Play. That triggered a review of the game: shortly after the update I received a message telling me Pixel Wheels was "not compliant with Google Play Policies". What nefarious activity does the game engage in? Sneak on users? Mine bitcoins? [...] Meanwhile you can still get the game from F-Droid or itch.io, since they do not have a problem with a link to a donation page. Read more
