@movq@www.uninformativ.de Yeah, give it a shot. At worst you know that you have to continue your quest. :-)

Fun fact, during a semester break I was actually a little bored, so I just started reading the Qt documentation. I didn’t plan on using Qt for anything, though. I only looked at the docs because they were on my bucket list for some reason. Qt was probably recommended to me and coming from KDE myself, that was motivation enough to look at the docs just for fun.

The more I read, the more hooked I got. The documentation was extremely well written, something I’ve never seen before. The structure was very well thought out and I got the impression that I understood what the people thought when they actually designed Qt.

A few days in I decided to actually give it a real try. Having never done anything in C++ before, I quickly realized that this endeavor won’t succeed. I simply couldn’t get it going. But I found the Qt bindings for Python, so that was a new boost. And quickly after, I discovered that there were even KDE bindings for Python in my package manager, so I immediately switched to them as that integrated into my KDE desktop even nicer.

I used the Python KDE bindings for one larger project, a planning software for a summer camp that we used several years. It’s main feature was to see who is available to do an activity. In the past, that was done on a large sheet of paper, but people got assigned two activities at the same time or weren’t assigned at all. So, by showing people in yellow (free), green (one activity assigned) and red (overbooked), this sped up and improved the planning process.

Another core feature was to generate personalized time tables (just like back in school) and a dedicated view for the morning meeting on site.

It was extended over the years with all sorts of stuff. E.g. I then implemented a warning if all the custodians of an activitiy with kids were underage to satisfy new the guidelines that there should be somebody of age.

Just before the pandemic I started to even add support for personalized live views on phones or tablets during the planning process (with web sockets, though). This way, people could see their own schedule or independently check at which day an activity takes place etc. For these side quests, they don’t have to check the large matrix on the projector. But the project died there.

Here’s a screenshot from one of the main views: https://lyse.isobeef.org/tmp/k3man.png

This Python+Qt rewrite replaced and improved the Java+Swing predecessor.

Epigenetic changes help cells adapt to low oxygen levels, study reveals
Researchers at Karolinska Institutet have discovered how cells can adjust their gene activity to survive when oxygen runs low. The study, published in Nature Cell Biology, reveals that cells use a previously unknown mechanism to control which proteins are produced—and how quickly. ⌘ Read more

Southern Ocean’s low-salinity Antarctic waters continue absorbing CO₂ despite climate model predictions
Climate models suggest that climate change could reduce the Southern Ocean’s ability to absorb carbon dioxide (CO2). However, observational data actually shows that this ability has seen no significant decline in recent decades. ⌘ Read more

Time crystals could power future quantum computers
A glittering hunk of crystal gets its iridescence from a highly regular atomic structure. Frank Wilczek, the 2012 Nobel Laureate in Physics, proposed quantum systems––like groups of particles––could construct themselves in the same way, but in time instead of space. He dubbed such systems time crystals, defining them by their lowest possible energy state, which perpetually repeats movements without external energy input. Time crystals were experimentall … ⌘ Read more

Sniffer dogs tested in real-world scenarios reveal need for wider access to explosives
Dogs aren’t just our best friends, they’re also key allies in the fight against terrorism. Thousands of teams of explosive detection dogs and their handlers work 24/7 at airports, transit systems, cargo facilities, and public events around the globe to keep us safe. But canine detection is an art as well as a science: success depends not only on the skill of both dog and human, but also on their bond, and may vary … ⌘ Read more

Generation of harmful slow electrons in water is a race between intermolecular energy decay and proton transfer
When high-energy radiation interacts with water in living organisms, it generates particles and slow-moving electrons that can subsequently damage critical molecules like DNA.

A rare variety of wheat with three ovaries—gene discovery could triple production
University of Maryland researchers discovered the gene that makes a rare form of wheat grow three ovaries per flower instead of one. Since each ovary can potentially develop into a grain of wheat, the gene could help farmers grow much more wheat per acre.

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos.

Almost 75,000 farmed salmon in Scotland escaped into the wild after Storm Amy. Why this may cause lasting damage
When Storm Amy battered the Scottish Highlands in early October, it tore through a salmon farm’s sea pens, releasing around 75,000 fish into open water in Loch Linnhe. The scale of the escape is alarming. It comes at a time when wild Atlantic salmon—already classified as “endangered” in Great Britain—are in decline. ⌘ Read more
