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.

Games: KeeperRL, Stellaris, SHEEPO, Depth of Extinction, Ufflegrim

  • KeeperRL, the fantastic mix of a dungeon simulator with roguelike and RPG bits has a new free version out

    Bored? Quarantine or Isolation due to the Coronavirus got you down? Time to check out a new game then. KeeperRL, a game that blends together a dungeon building sim with a roguelike and RPG mechanics has a free build up. Technically, you could get a free copy of KeeperRL before as the developer has given it away free for a long time—however that was the ASCII version with no proper graphics. It's code is also open source under the GPL...

  • Paradox confirm a large free update for Stellaris in May, and it hit a big concurrent player peak recently

    Stellaris recently gained the massive Federations expansion, and now that's out the door Paradox Interactive and Paradox Development Studio are looking ahead towards a big free update due in May. Before we get into that, it looks like the popularity of Stellaris has been renewed somewhat since Federations launch. Stellaris hit a peak concurrent player count of over 64 thousand in March, the highest since release 4 years ago. Since then, it's still regularly seeing higher than normally player counts.

  • Quirky metroidvania platformer 'SHEEPO' has you steal eggs and gain transformation powers

    SHEEPO, a new upcoming 'quirky' metroidvania platformer recently appeared on Steam, and it instantly pulled in my attention due to the beautiful style. When they describe it as quirky, they're certainly not wrong. You play as some sort of shape-shifting sheep-thing, travelling across an uncharted planet. Why? You're collecting samples of each living species for an intergalactic species database. You can't just grab a fully grown creature though, you have to search to find their eggs. They're guarded of course, so you have to overcome the Queen of each species. Once you manage to collect the egg, you then get the ability to transform into it.

  • Tactical RPG 'Depth of Extinction' gains a revamp with a Definitive Edition out now

    HOF Studios have given their tactical RPG with turn-based combat, Depth of Extinction, a full makeover with a fresh Definitive Edition as a massive free update. Blending together elements of FTL and XCOM, it didn't get the best reviews (Mixed overall) and at release largely went unnoticed (until the Steam key debacle anyway). Still, thankfully, the developer kept at it and they've tried to expand it, while also removing or replacing elements that didn't work well in this new Definitive Edition. You can now switch between characters instead of it using an initiative system (so it's more like XCOM), there's Stealth and Ambushes now, more mech units, the game loop has been shortened down from around 20 hours to 10, a brand new tutorial and so on. It's a whole new game feel.

  • Ufflegrim is the most bizarre deck-builder yet but it looks awesome and it's out now

    Ufflegrim, a new release from Corpse King Games arrived yesterday looks absolutely bizarre blending together a deck-builder with a roguelike. All the mechanics together make it sound thoroughly unique too. With 100 floors to travel through and clear, you need to collect creatures which form your deck. However, it's not quite a standard 'one card equals one creature' mechanic, as you appear to be able to play one card on top of another to act like some sort of buff to the existing creature. You also have your own movement to take care of, while watching out for all the other nasties around the floor.

Announcing the LibreOffice Help editor

News from the documentation community: The Help project of LibreOffice underwent a major revamp in the last couple of years, with the introduction of the browser-based Help replacing the old Writer-Web solution. Still, editing the Help XML files (XHP) continued to be very hard for any volunteer or skilled developer, due to the specifics of the XML dialect and time required to be proficient in writing Help pages, which continued to be a major block for any individual. To address the issue, we developed an online editor to assist and make textual editing quicker for any Help writer, by featuring the possibility of rendering the help page at once, at the click of a button. Also, we implemented a series of checking, including XML validity and the verification of ID unicity, crucial for translation. Read more
