KDE/Qt: Qt Contributor Summit 2018, Integrating Cloud Solutions with Qt, FreeBSD, and Konsole

Qt Contributor Summit 2018
One bit especially interesting is the graphics stack. Back in Qt 5.0, Qt took the liberty of limiting the graphics stack to OpenGL, but the world has changed since: On Windows the only proper stack is Direct3D 12, Apple introduced Metal and recently deprecated OpenGL and Vulkan is coming rather strong. It looks like embracing these systems transparently will be one of the most exciting tasks to achieve. From a KDE & Plasma perspective I don’t think this is scary, OpenGL is here to stay on Linux. We will get a Framework based on a more flexible base and we can continue pushing Plasma, Wayland, Plasma Mobile with confidence that the world won’t be crumbling. And with a bit of luck, if we want some parts to use Vulkan, we’ll have it properly abstracted already.

Integrating Cloud Solutions with Qt
These days, using the cloud for predictive maintenance, analytics or feature updates is a de facto standard in the automation space. Basically, any newly designed product has some server communication at its core.
However, the majority of solutions in the field were designed and productized when communication technology was not at today’s level. Still, attempts are being made to attach connectivity to such solutions. The mission statement is to “cloudify” an existing solution, which uses some internal protocol or infrastructure.

KDE on FreeBSD – June 2018
It’s been a while since I wrote about KDE on FreeBSD, what with Calamares and third-party software happening as well. We’re better at keeping the IRC topic up-to-date than a lot of other sources of information (e.g. the FreeBSD quarterly reports, or the f.k.o website, which I’ll just dash off and update after writing this).

Konsole’s search tool
Following my konsole’s experiments from the past week I came here to show something that I’m working on with the VDG, This is the current Konsole’s Search Bar.
[...]
I started to fix all of those bugs and discovered that most of them happened because we had *one* search bar that was shared between every terminal view, and whenever a terminal was activated we would reposition, reparent, repaint, disconnect, reconnect the search bar. Easiest solution: Each Terminal has it’s own search bar. Setuped only once. The one bug I did not fix was the Opening / Closing one as the searchbar is inside of a layout and layouts would reposition things anyway.
All of the above bugs got squashed by just moving it to TerminalDisplay, and the code got also much cleaner as there’s no need to manual intervention in many cases. On the review Kurt – the Konsole maintainer – asked me if I could try to make the Search prettier and as an overlay on top of the Terminal so it would not reposition things when being displayed.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
