  • Introducing Qt Quick 3D: A high-level 3D API for Qt Quick

    As Lars mentioned in his Technical Vision for Qt 6 blog post, we have been researching how we could have a deeper integration between 3D and Qt Quick. As a result we have created a new project, called Qt Quick 3D, which provides a high-level API for creating 3D content for user interfaces from Qt Quick. Rather than using an external engine which can lead to animation synchronization issues and several layers of abstraction, we are providing extensions to the Qt Quick Scenegraph for 3D content, and a renderer for those extended scene graph nodes.

    Does that mean we wrote yet another 3D Solution for Qt? Not exactly, because the core spatial renderer is derived from the Qt 3D Studio renderer. This renderer was ported to use Qt for its platform abstraction and refactored to meet Qt project coding style.

  • The Qt Company Announces Its New High-Level 3D API - Qt Quick 3D

    Continuing on from the recent technical vision for the Qt6 tool-kit, The Qt Company has now announced their new high-level 3D API they are developing for this next major release of Qt.

    Qt Quick 3D is this new high-level API for creating 3D content for user-interfaces out of Qt Quick without the need for any external engine. Qt Quick 3D will make use of the renderer currently employed by the Qt 3D STUDIO.

  • Implementing a derivated class of kis_brushes_pipe

    I am still working on the change of the brush index, so far I've been confused with the classes, because I am not sure why somethings are implemented and then overriden or why somethings are where they are, and I am not sure exactly when or why to do this.

    I've been working all week, instead of trying to deliver a feature I tried to write and organize the whole class, and then slowly write all the small functions, this is because I've had problem with classes and objects, but I understand functions, so I to tried work with my strengths.

Debian: Introducing Noir, miniDebConf19 Vaumarcus and New FAI.me Feature

  • Introducing Noir

    Noir is a drop-in replacement for Black (the uncompromising code formatter), with the default line length set to PEP-8's preferred 79 characters. If you want to use it, just replace black with noir in your requirements.txt and/or setup.py and you're good to go. Black is a Python code formatter that reformats your code to make it more PEP-8 compliant. It implements a subset of PEP-8, most notably it deliberately ignores PEP-8's suggestion for a line length of 79 characters and defaults to a length of 88. I find the decision and the reasoning behind that somewhat arbitrary. PEP-8 is a good standard and there's a lot of value in having a style guide that is generally accepted and has a lot of tooling to support it. When people ask to change Black's default line length to 79, the issue is usually closed with a reference to the reasoning in the README. But Black's developers are at least aware of this controversial decision, as Black's only option that allows to configure the (otherwise uncompromising) code formatter, is in fact the line length. Apart from that, Black is a good formatter that's gaining more and more popularity. And, of course, the developers have every right to follow their own taste. However, since Black is licensed under the terms of the MIT license, I tried to see what needs to be done in order to fix the line length issue.

  • miniDebConf19 Vaumarcus – Oct 25-27 2019 – Registration is open

    The Vaumarcus miniDebConf19 is happening! Come see the fantastic view from the shores of Lake Neuchâtel, in Switzerland! We’re going to have two-and-a-half days of presentations and hacking in this marvelous venue and anybody interested in Debian development is welcome.

  • New FAI.me feature

    FAI.me, the build service for installation and cloud images has a new feature. When building an installation images, you can enable automatic reboot or shutdown at the end of the installation in the advanced options. This was implemented due to request by users, that are using the service for their VM instances or computers without any keyboard connected.

FreeBSD's Executive Director Calls For Linux + BSD Devs To Work Together

While called the Open-Source Summit, the event is primarily about Linux as after all it's hosted by the Linux Foundation. But at this week's Open-Source Summit in San Diego, Deb Goodkin as the executive director of the FreeBSD Foundation presented. Deb's talk was of course on FreeBSD but also why FreeBSD and Linux developers should work together. The presentation covered FreeBSD's development workflow and various features of this open-source operating system project for those unfamiliar as well as some of the companies utilizing FreeBSD and their different use-cases. It's a good overview for those not familiar with FreeBSD. Read more

LG Has Been Working On Reduced Boot Times With Hibernation Optimizations

LG Electronics has been exploring improvements around hibernation/suspend-to-disk to speed-up the Linux boot process for consumer electronics rather than performing cold boots and as part of that is working towards upstream optimizations. While hibernation-based booting is generally quicker than performing cold boots, suspending to disk does yield extra writes to the NAND flash memory on these consumer devices and that is one of the things they are seeking to avoid. So it's been an effort not only to speed-up the hibernation boot process but also reducing the amount of data that needs to be written out to the flash storage. Read more
