Inspired and motivated by a couple of PWAs I have recently written, I have just revived and rewritten a little puzzle game, I have once written in Delphi (Pascal) for the first time.
Feel free to have a look, try to set some records and be my first testers ;)

As usual, feedback and ideas are welcome …
It took some time, but now I finally managed to finish the next twist in Particle Twister.
My game idea that I designed and realised together with Katarina Anthony during my ‘more active’ time at the ATLAS Experiment at CERN finally got the first set of long-promised playing cards for additional fun and challenges in addition to the classic spinning wheel – all that in my brand new Progressive Web App (PWA).
You can use it online at and install it locally from https://particle-twister.mehlhase.info/.
Let me know if you have more ideas for cards, playing modes or features.
I still have a few more ideas, so stay tuned for updates …
Last week, I took part in the “International Conference for High Performance Computing, Networking, Storage, and Analysis” for the fourth time*, representing Munich Quantum Valley (MQV) and showcasing its activities at the Leibniz Supercomputing Centre (LRZ) booth.
* after SC22 in Dallas, SC23 in Denver, and SC24 in Atlanta
Ever had an issue with people not sticking to their allocated presentation time at one of your events? I certainly do …
After another round of testing at our MQV Annual Meeting in Eichstätt in October, I put together a new version of my little timekeeping tool available at timekeeper.mehlhase.info.
I usually have it running on a Raspberry Pi using Chromium in kiosk mode and use chroma keying on an ATEM Mini Pro to overlay the presentation source with the timer display, all controlled by a tiny five-keys ‘keyboard’. But it’s a Progressive Web App, so you can install it locally on your PC, tablet or phone and hook that up your video mixer via HDMI.
Last week, I was at the 2025 IEEE Quantum Week in Albuquerque, New Mexico, to once again represent Munich Quantum Valley (MQV) with a special focus on its quantum-software activities and the Munich Quantum Software Stack (MQSS).
I also had the opportunity to fly on an Airbus A380 for the first time. Unfortunately, I missed my connecting flight on the way back, so I had to spend an extra night near Denver and wait another two days for my checked luggage to arrive.
