Astronomy for KDE

Filed under
KDE

Although I have covered a large number of science applications in the past, I haven't really looked at too many options available within the KDE desktop environment. This has been due to my own biases in using a GTK-based desktop environment, but now I'd like to look at some of the packages available for people who really like to use KDE on their own machines. So, let's start with the KStars astronomy program.

  • Wayland in Plasma 5.7

    Last week we released the beta version of Plasma 5.7 which means we know what this release will have for better Wayland support. First of all I need to mention what didn’t make it: unfortunately I missed the freeze of Frameworks 5.23 to land support for xdg-shell. I have a working implementation, but was not yet satisfied with the API. This is a difficult interface to provide an API for due to the unstable nature of the interface. Due to lack of xdg-shell support GTK applications are still going to use X11 on Wayland (like the Firefox window I’m just typing this blog post in).

  • The State Of Wayland For KDE Plasma 5.7

    There are a lot of Wayland support improvements to find in the upcoming release of KDE's Plasma 5.7.

    Wayland advancements for KDE Plasma 5.7 include the improved task manager, virtual keyboard support, sub-surface support, improved input device support, and more. However, missing from Plasma 5.7 is their XDG-Shell support as the API wasn't stabilized in time.

  • Qt 5.6.1-1 Released

    The problem with Qt 5.6.1, reported in QTBUG-53761, is that certain Qt Quick applications crash after some time. The problem occurs with code that loads more than 64 components (.qml or .js files) without instantiating objects from all of them. The components that initially don’t get instantiated will then be removed from the type cache, which causes problems if you later try to instantiate objects from them. Reason for the problem is too aggressive trimming of the QML type cache, which ends up deleting some QML types even though they were still in use by the application.

  • Qt 5.6.1-1 Released To Fix A Critical Problem

    Qt 5.6.1 was released earlier this month to fix outstanding issues with the Qt 5.6 tool-kit release while today the 5.6.1-1 hot-fix release is available to fix a critical problem.

    Slipping into Qt 5.6.1 was a regression that prevented certain types of Qt Quick applications from working correctly. This issue with Qt 5.6.1 would cause Qt Quick applications to crash but did not affect the newer Qt 5.7.0 release.

  • Call for submissions for the 2016 Art of Krita Book

    The Krita Foundation is going to publish a glossy, shiny book of art created with Krita! This book will be sent out to the seventy Kickstarter backers who selected the artbook as their reward, and it will be available from the Krita shop. We’ll also try and make sure it’s available through online bookshops! It’s the very first time the Krita Foundation will publish a book, and we’re really excited about it.

  • Farewell to the Mountains

    So the last train has left Randa, and we can look back at a — judging from the bugs that were fixed and the ideas that were traded and the code that was written — successful sprint. The last two days were characterized by the authentic Randa Internet experience, in which a mountain goat eats 18% of the packets, but that doesn’t stop KDE developers from writing code and sharing AppImages.

    KDE neon User Edition 5.6 came out a couple of weeks ago, let’s have a look at the commentry.

  • My LaKademy 2016

    In the end of May, ~20 gearheads from different countries of Latin America were together in Rio de Janeiro working in several fronts of the KDE. This is our ‘multiple projects sprint’ named LaKademy!

    Like all previous editions of LaKademy, this year I worked hard in Cantor; unlike all previous editions, this year I did some work in new projects to be released in some point in the future. So, let’s see my report of LaKademy 2016.

  • Doxyqml 0.3.0 released

    The master branch of Doxyqml, a QML input filter for Doxygen, had been waiting for a release for a long time. Olivier Churlaud, the new KApidox hero, reported that it did not work with Python 3 and submitted a patch to fix this.

  • Cutelyst 0.12.0 is out!

    Cutelyst a web framework built with Qt is now closer to have it’s first stable release, with it becoming 3 years old at the end of the year I’m doing my best to finally iron it to get an API/ABI compromise, this release is full of cool stuff and a bunch of breaks which most of the time just require recompiling.

  • Peruse 1.0 "The Birthday Release"

    One day, about half a year or so ago, it came up in a discussion that while we in KDE have a lovely document viewer named Okular, we don't have something that is well suited to actually reading things, comic books in particular. So, a project was hatched to fix this. I've blogged about it before, and made a few tweets on the topic, but today is special. Today, 1.0 happens.

KDE Neon: The Rock & Roll Distribution

Filed under
KDE

What does it mean when developers behind one of the world's most popular desktop environments decide to jump into the deep end and fork a distribution? Depending on who you ask you’ll hear madness, excellence, confusion, and excitement as onlookers figure out the exact nature of a new breed of beast and guess what it will do.

KDE neon is a new distribution freshly forked from Ubuntu being driven by prominent KDE contributors and figures. When initially announced some mixed messages marred the event, but since then the project has found its footing and expectations are seemingly being set...

Neon is entirely unique as a product produced by a community which always made generalist software; Plasma and KDE software is offered by Suse, Red Hat, Arch, Slack, any distribution you can name. Neon is in direct competition with those systems, and several people decried this new distribution as opening the potential for favouritism.

  • The Qt Company Is Still Aiming To Get Qt 5.8 Out This Year

    This year has already encountered the releases of the much-delayed Qt 5.6 followed quite quickly by Qt 5.7.

  • QtWebKit Technology Preview 2
  • New Technology Preview Of QtWebKit

    There's a new technology preview release of QtWebKit for those wanting to use this formerly retired WebKit-based module instead of the newer QtWebEngine that makes use of Chromium's Blink engine.

    As covered earlier this month, QtWebKit has been aiming for a return by interested developers wishing to continue to leverage WebKit in Qt applications rather than moving over to Qt WebEngine. Konstantin Tokarev who has been leading the revival on QtWebKit announced the release of its second technology preview release.

  • GSoC 2016: Soft proofing, Gamut alarms and looks update.

    Partially, this week was spent on me recuperating from my exam-week and the Krita Kickstarter. After that, delving into the jungle that is Pigment, which is Krita’s colour management library, for abstracting the caching and handling of colour managed colours. It’s a bit of a jungle of templates and class inheritance. This part is where living at my mentor for a week was helpful, as communicating some of the problems I bumped into(mostly confusing class names and how to avoid having to rewrite the caching graph), would’ve been too difficult to do over IRC.

  • The 2016 Kickstarter

    This year's kickstarter fundraising campaign for Krita was more nerve-wracking than the previous two editions. Although we ended up 135% funded, we were almost afraid we wouldn't make it, around the middle. Maybe only the release of Krita 3.0 turned the campaign around. Here's my chaotic and off-the-cuff analysis of this campaign.

  • After the hype: Where containers make sense for IT organizations
    Container software and its related technologies are on fire, winning the hearts and minds of thousands of developers and catching the attention of hundreds of enterprises, as evidenced by the huge number of attendees at this week’s DockerCon 2016 event. The big tech companies are going all in. Google, IBM, Microsoft and many others were out in full force at DockerCon, scrambling to demonstrate how they’re investing in and supporting containers. Recent surveys indicate that container adoption is surging, with legions of users reporting they’re ready to take the next step and move from testing to production. Such is the popularity of containers that SiliconANGLE founder and theCUBE host John Furrier was prompted to proclaim that, thanks to containers, “DevOps is now mainstream.” That will change the game for those who invest in containers while causing “a world of hurt” for those who have yet to adapt, Furrier said.
  • Is Apstra SDN? Same idea, different angle
    The company’s product, called Apstra Operating System (AOS), takes policies based on the enterprise’s intent and automatically translates them into settings on network devices from multiple vendors. When the IT department wants to add a new component to the data center, AOS is designed to figure out what needed changes would flow from that addition and carry them out. The distributed OS is vendor-agnostic. It will work with devices from Cisco Systems, Hewlett Packard Enterprise, Juniper Networks, Cumulus Networks, the Open Compute Project and others.

Industrial SBC builds on Raspberry Pi Compute Module

On Kickstarter, a “MyPi” industrial SBC using the RPi Compute Module offers a mini-PCIe slot, serial port, wide-range power, and modular expansion. You might wonder why in 2016 someone would introduce a sandwich-style single board computer built around the aging, ARM11 based COM version of the original Raspberry Pi, the Raspberry Pi Compute Module. First off, there are still plenty of industrial applications that don’t need much CPU horsepower, and second, the Compute Module is still the only COM based on Raspberry Pi hardware, although the cheaper, somewhat COM-like Raspberry Pi Zero, which has the same 700MHz processor, comes close.
