On Monday, KDE’s Plasma team held its traditional kickoff meeting for the new development cycle. We took this opportunity to also look and plan ahead a bit further into the future. In what areas are we lacking, where do we want or need to improve? Where do we want to take Plasma in the next two years?
Our general direction points towards professional use-cases. We want Plasma to be a solid tool, a reliable work-horse that gets out of the way, allowing to get the job done quickly and elegantly. We want it to be faster and of better quality than the competition.
With these big words out there, let’s have a look at some specifics we talked about.
Release schedule until 2018
Our plan is to move from 4 to 3 yearly releases in 2017 and 2018, which we think strikes a nice balance between our pace of development, and stabilization periods around that. Our discussion of the release schedule resulted in the following plan:
- Plasma 5.9: 31 January 2017
- Plasma 5.10: May 2017
- Plasma 5.11: September 2017
- Plasma 5.12: December 2017
- Plasma 5.13: April 2018
- Plasma 5.14 LTS: August 2018
A cautionary note, we can’t know if everything exactly plays out like this, as this schedule, to a degree depends on external factors, such as Qt’s release schedule. Here’s what we intend to do, it is really our “best guess”. Still, this aligns with Qt’s plans, who are also looking at an LTS release in summer 2018. So, what will these upcoming releases bring?
UI and Theming
The Breeze icon theme will see further completion work and refinements in its existing icons details. Icon usage over the whole UI will see more streamlining work as well. We also plan to tweak the Breeze-themed scrollbars a bit, so watch out for changes in that area. A Breeze-themed Firefox theme is planned, as well as more refinement in the widget themes for Qt, GTK, etc.. We do not plan any radical changes in the overall look and feel of our Breeze theme, but will further improve and evolve it, both in its light and dark flavors.
One thing that many of our users are missing is support for a global menu similar to how MacOS displays application menus outside of the app’s window (for example at the top of the screen). We’re currently working on bringing this feature, which was well-supported in Plasma 4 back in Plasma 5, modernized and updated to current standards. This may land as soon as the upcoming 5.9 release, at least for X11.
Better support for customizing the locale (the system which shows things like time, currencies, numbers in the way the user expects them) is on our radar as well. In this area, we lost some features due to the transition to Frameworks 5, or rather QLocale, away from kdelibs’ custom, but sometimes incompatible locale handling classes.
The next releases overall will bring further improvements to our Wayland session. Currently, Plasma’s KWin brings an almost feature-complete Wayland display server, which already works for many use-cases. It hasn’t seen the real-world testing it needs, and it is lacking certain features that our users expect from their X11 session, or new features which we want to offer to support modern hardware better.
We plan to improve multi-screen rendering on Wayland and the input stack in areas such as relative pointers, pointer confinement, touchpad gestures, wacom tablet support, clipboard management (for example, Klipper). X11 dependencies in KWin will be further reduced with the goal to make it possible to start up KWin entirely without hard X11 dependencies.
One new feature which we want to offer in our Wayland session is support for scaling the contents of each output individually, which allows users to use multiple displays with vastly varying pixel densities more seamlessly.
There are also improvements planned around virtual desktops under Wayland, as well as their relation to Plasma’s Activities features. Output configuration as of now is also not complete, and needs more work in the coming months. Some features we plan will also need changes in QtWayland, so there’s some upstream bug-fixing needed, as well.
One thing we’d like to see to improve our users’ experience under Wayland is to have application developers test their apps under Wayland. It happens still a bit too often that an application ends up running into a code-path that makes assumptions that X11 is used as display server protocol. While we can run applications in backwards-compatible XWayland mode, applications can benefit from the better rendering quality under Wayland only when actually using the Wayland protocol. (This is mostly handled transparantly by Qt, but applications do their thing, so unless it’s tested, it will contain bugs.)
Plasma’s Mobile flavor will be further stabilized, and its stack cleaned up, we are further reducing the stack’s footprint without losing important functionality. The recently-released Kirigami framework, which allows developers to create convergent applications that work on both mobile and desktop form-factors, will be adjusted to use the new, more light-weight QtQuick Controls 2. This makes Kirigami a more attractive technology to create powerful, yet lean applications that work across a number of mobile and desktop operating systems, such as Plasma Mobile, Android, iOS, and others.
Planned improvements in our integration of online services are dependency handling for assets installed from the store. This will allow us to support installation of meta-themes directly from the KDE Store. We want to also improve our support for online data storage, prioritizing Free services, but also offer support for proprietary services, such as the GDrive support we recently added to Plasma’s feature-set.
We want to further increase our contributor base. We plan to work towards an easier on-boarding experience, through better documentation, mentoring and communication in general. KDE is recruiting, so if you are looking for a challenging and worthwhile way to work as part of a team, or on your individual project, join our ranks of developers, artists, sysadmins, translators, documentation writers, evangelists, media experts and free culture activists and let us help each other.
I’ve always loved diving down while snorkeling or swimming, and it’s been intriguing to me how long I can hold my breath, how far and deep I could go just like that. (The answer so far, 14m.)
Last week, I met with Jeanine Grasmeijer. Jeanine is one of the world’s top freedivers, two times world record holder, 11 times Dutch national record holder. She can hold her breath for longer than 7 minutes. Just last month she dove down to -92m without fins. (For the mathematically challenged, that’s 6.6 times 14m.)
Jeanine showed me how to not breathe properly.
We started with relaxation and breathing exercises on dry land. Deep relaxation, breathing using the proper and most effective technique, then holding breath and recovering.
In the water, this actually got a bit easier. Water has better pressure characteristics on the lungs, and the mammalian diving reflex helps shutting off the air ways, leading to a yet more efficient breath hold. A cycle starts with breathing in the water through the snorkel for a few minutes, focusing on a calm and regular, relaxed breathing rhythm. After a few cycles of static apnea (breath holding under water, no movement), I passed the three-minute-mark at 3:10.
We then moved on to dynamic apnea (swimming a horizontal distance under water on one breath). Jeanine did a careful weight check with me, making sure my position would need as little as possible correction movements while swimming. With a reasonable trim achieved, I swam some 50m, though we mainly focused not on distance, but on technique of finning, arms usage and horizontal trim.
The final exercise in the pool was about diving safety. We went over the procedure to surface an unconscious diver, and get her back to her senses.
Freediving, as it turns out, is a way to put the world around on pause for a moment. You exist in the here and now, as if the past and future do not exist. The mind is in a completely calm state, while your body floats in a world of weightless balance. As much as diving is a physical activity, it can be a way to enter a state of Zen in the under water world.
Jeanine has not only been a kind, patient and reassuring mentor to me, but opened the door to a world which has always fascinated and intrigued me. A huge, warm thanks for so much inspiration of this deep passion!
The Ocean Warrior, the newest vessel in Sea Shepherd‘s fleet docked in Amsterdam before beginning its voyage to the Southern Ocean around Antarctica to prevent poachers from killing whales. Sea Shepherd is a marine conservation society that employs direct action to protect marine wildlife. The Ocean Warrior is a 54m custom-built vessel, hosting a crew of 16. It’s very fast, reaching almost 30 knots at top speed. It is powered by 4 3000 horse power engines, and features an open deck at the stern with a hefty water cannon.
The Ocean Warrior is an incredibly slick and strictly functional master-piece of ship engineering. Its solid build makes it a tool suitable for the extreme conditions around Antarctica.
Its unusually high top-speed will give the Sea Shepherd fleet a huge strategic advantage in the vast wideness of the Southern Ocean.
