A better Qt because of Open Source and KDE

Filed under
Development
KDE

The development framework Qt is available both as Open Source and under paid license terms. Two decades ago, when Qt 2.0 was first released as Open Source, this was exceptional. Today, most popular developing frameworks are Free/Open Source Software1. Without the dual licensing approach, Qt would not exist today as a popular high-quality framework.

There is another aspect of Qt licensing which is still very exceptional today, and which is not as well-known as it ought to be. The Open Source availability of Qt is legally protected through the by-laws and contracts of a foundation.

The KDE Free Qt Foundation was created in 1998 and guarantees the continued availability of Qt as Free/Open Source Software2. When it was set up, Qt was developed by Trolltech, its original company. The foundation supported Qt through the transitions first to Nokia and then to Digia and to The Qt Company.

In case The Qt Company would ever attempt to close down Open Source Qt, the foundation is entitled to publish Qt under the BSD license. This notable legal guarantee strengthens Qt. It creates trust among developers, contributors and customers.

The KDE Free Qt Foundation is a cooperation between The Qt Company on the one hand and KDE on the other hand. KDE is one of the largest Free Software communities for general purpose end-user software, founded in 1996. In case of ties, KDE has an extra vote, ensuring that The Qt Company does not have a veto on decisions.

My in-depth presentation below provides an overview of the history of the Foundation and describes its importance for Qt today. It explains in detail why the existence of the Foundation has a positive influence on the long-term market success of Qt.

VPN Providers with Custom Clients for Linux

Virtual Private Networking providers and company are more than you can shake a stick at these days. While there's always installable client software for Windows, Android and usually MacOS and whatever the mobile version is called not all are offering desktop clients for Linux distributions. Even if they do it's usually non-GUI, you know, with the excuse that Linux nerds love and want the power of the command line, with stripped-down functionality, or even a browser extension only which might work on a Chromebook but not on any other OS if you actually want to channel your entire traffic. And no, a proxy is not a replacement for a proper VPN. Another constraint is the various packaging formats Linux and GNU/Linux distributions are using. Most providers only offer packages for Debian and Ubuntu-like distributions. RPMs are typically Fedora and/or CentOS but do not work on SUSE. On other distributions like Slackware and Arch you're basically on your own. You can hope that someone has provided a build on sbopkg for Slackware or in the AUR for the Arch base or that it can be transformed with the alien packaging tool but these are not official packages. Then we have the issue of different init systems in use all over the Linux install base. When exploring Artix Linux I discovered that custom desktop client software is written to work with distributions that are using systemd to handle services and networking. Wanting to use them with OpenRC or Runit presents a bit of a challenge. It can be done but you got to know your init system's run levels or ask a distro developer to package it for you. Thankfully I since discovered that the software of at least two companies I'm perusing supports SysVinit. Their packages worked flawlessly on Devuan 3.0 so all is not lost if you're not running systemd but still want to use your providers client instead of the Networkmanager OpenVPN plugin. Even more so since NM does not seem to work without systemd, haha. They also play nicely with Wicd, no conflicts there. They're not integrated but they don't integrate with NM either. Read more

  • 20 years of Drupal: Founder Dries Buytaert on API first, the end of breaking compatibility, and JavaScript bloat

    Content management system Drupal is 20 years old, prompting its founder to talk to about its evolving role, why it shifted from a policy of breaking compatibility with each release, and concerns about JavaScript bloat causing issues for those with poor connectivity. "When I started Drupal 20 years ago I built it for myself, for me with my friends," Buytaert told us. That was at the University of Antwerp, Belgium, in 2000. He wrote a small message board. When he graduated he put it on the web, intending to call it dorp, which is Dutch for village. He mistyped it as drop, creating drop.org. Drupal is derived from the English pronunciation of druppel, Dutch for drop. Buytaert is now project lead for Drupal and CTO of Acquia, a cloud platform for marketing sites.

  • What Can We Learn From SQL’s 50 Year Reign? A Story of 2 Turing Awards

    Many of the programming languages we use today were not introduced until the 90s (Java was introduced in 1996). However, there is one programming language that is still as popular today as it was when it was introduced nearly 50 years ago: SQL.

    This article will discuss the events that led to the introduction of relational databases, why SQL grew in popularity, and what we can learn from its success.

    Given no one seems to be interested in working on the applet (boo) I decided to tackle the bug myself. Apparently the fact it worked previously was the result of happenstance.

  • 5 Best free PDF editors for Ubuntu Linux in 2021 [Ed: Some of these are proprietary software, which GNU/Linux users do not need for any practical reason]

    PDF readers and editors are a popular part of our day-to-day work related to documents, ebooks, presentations, whitePaper, and more because of PDF’s portability and security. However, when it comes to reader application for PDF files, you will generally find a one on Linux desktop systems, easily. However, PDF editors may still need to be installed, which are available only a handful. Adobe developed the PDF (portable document format) in such a way that it can present the layout in the final document as it is, anywhere, regardless of the OS system or software in which you are going to use it later. Therefore, editing PDF files afterward is not an easy task- apart from the standard note and comment functions. However, Adobe offers a professional PDF editor for Mac and Windows but that also has limited capabilities. This means we can edit all PDF files not thoroughly like we do Word documents.
