KDE and Qt: GCompris, Krita, Qt and QML

GCompris- Digital Electricity
The Digital Electricity activity in GCompris aims at creating and simulating a digital electric schema. Currently, there exists a “Free Mode”, where a user can freely create and check the working of a circuit on their own. During the final month of the GSoC period, I will be adding a “Tutorial Mode” alongside the existing free mode. The tutorial mode is aimed at teaching the users how the individual components work in a digital circuit.

Krita 3.2.0: We Have a Release Candidate!
After last week’s rollercoaster ride (if you haven’t seen it, check the news, then the update!), it was hard to get back into making releases and writing code. Yet, here is the release candidate for Krita 3.2.0.

New in Qt 5.10: Diagnostics when breaking QML bindings
Property bindings are one of the most interesting features of the QML language. In QML, when we set a value on a property, the right hand side expression isn’t evaluated just once to produce a value, like in a ordinary imperative language.

If your software should be cross platform and accessible, forget about Qt
A few years ago, I started to write software which primary audience is going to be blind musicians. I did a small presentation of the UI at DebConf15.
Most of the functionality is in a compiler-alike backend. But eventually, I wanted to create a user interface to improve the interactive experience.
So, the problem again: which toolkit to choose which would be accessible on most platforms? Last time I needed to solve a similar problem, I used Java/Swing. This has its problems, but it actually works on Windows, Linux and (supposedly) Mac. This time around, my implementation language is C++, so Swing didn't look that interesting. It appears there is not much that fullfils these requirements. Qt looked like it could. But since I had my bad experiences already with Qt claiming accessibility they really never implemented, I was at least a bit cautious. Around 10 years ago, when Qt 4 was released, I found that the documentation claimed that Qt4 was accessible on Linux, but it really never was until a very late 4.x release. This information was a blatant lie, trying to lure uninformed programmers into using Qt, much to the disservice of their disabled users. If you ask a random blind Windows user who knows a bit about toolkits, they will readily tell you that they hate every app written in Qt.

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. |
