Uhm, "General Medicine" small, and "Homeopathy" very large. I wouldn't go to see this doctor!

So unusual, empty train today...

I'm at the STI-ENID conference in Bristol now. Amazing place, I feel like Harry Potter in here 

It's quite and peaceful #UBC at night. That was yesterday. Now, starting #acmrep25 in 30 min!

This is the #PCB of a bootleg #Pacman arcade game. I bought it almost as trash, not working, and I'm repairing it. Why? Well... many of us had the opportunity to see 80's microinformatics develop fast and in a way it's part of our heritage. If I don't repair it, it would simply get more rusted and end up destroyed. But I want to keep it alive and to work again. It will. It's, somehow, a part of me.

The other day in the European Parliament, exceptional venue for the AIvolution meeting! I had the opportunity to meet great people working on several aspects around AI. Very professional organization of the event, by the way.

I have, literally, an image of the #Sun on my door. Indeed, when light arrives at a #pinhole camera, it produces an inverted image of the source. In this case, our Sun. I don't have such a camera, just a small hole (of any shape) in the blinds of my window. #science

In #spectroscopy one can observe the energy levels from the #electron transitions in their orbitals. It's amazing to see how it's not continuous, but the bands appear in very specific points of the spectrum, showing its quantum nature. It's also very interesting to see the spin of the electron (the two bands which are very close to each other) in the spectrum of the #hydrogen fine structure: it's quantized. Nothing new, but amazing #quantum #physics

I'm spending some time these days on my #retrocomputing project, trying to know when the good old #v9918 VDP reads the memory. This could help emulators such as #openMSX be improved. Or perhaps I obtain exactly the same as we already know! Now I have some fun ahead trying to connect an #NMOS chip at 5v to a modern ESP32, which is CMOS and 3.3v. Level shifter ICs are too slow for these signals, so I need to use voltage dividers with the internal NMOS resistor. Fun ahead! #MSX
