A magyar közszféra mikor fogja végre kikukázni a windowst?

Most, hogy Európa kezd végre magához térni, és nyugaton sorra dobják ki a windowst a közszférából és térnek át Linuxra (legutóbb pl. a franciák jelentették be, hogy bojkottálják a M$-ot, 2.5M gépről törlik a win-t, és ejtik az ai- és felhő-szolgáltatásaikat is), természetes módon adódik a kérdés, hogy Mo. mikor fogja követni ezt az üdvözítő trendet?

Van erről valakinek valamilyen infója? Elindult már a szakmában ennek a követelése?

Mit gondoltok, van-e értelme ismét feltámasztani az UHU Linuxot, vagy megfelelő lenne-e egyszerűen valamelyik népszerű disztribúcióra átállni?

Asymmetrical frequency modulated signal

I'd like to have a closed formula for a frequency modulated signal that oscillates between 2* |sin(Omega(envelope)*t)| and - |sin(Omega(envelope)*t)|, see figure.

I know it's a heavily underdetermined problem, I'm looking for the most natural solution and nicest solution (continuous, smooth etc): imagine we start from the symmetrical case: sin(Omega(envelope)*t) * sin(Omega(carrier)* t), and then "strech" the signal towards the positive direction.

I'm looking for some textbook and/or review paper that discusses the properties of finite-sized (quantum) Heisenberg models, preferably analytical results. Level structures, multiplets, magnetic behavior, effects of anisotropy etc.

Can you recommend some literature on this?

Especially in the 2nd and 3rd brewing I oftentimes experience quite some tannins. How to reduce them? Should I go for lower water temperatures, or should I reduce steeping time?

A new column has appeared after BOM and POS called POP. What does this mean?

At several components the POP takes False value (red cross), and these components do not appear in the BOM. I do not know what's going on, all of these components are supposed to be populated, and none of them is marked as DNP or anything related. The plugin does not offer any button to toggle this POP value, so I'm not even sure how to "re-activate" these components.

Anyone else experiencing this issue? I'm using version 2026.04.03 with KiCad 10.0.1.

EDIT:
Might be a deeper issue. IC1 is one of these components. When I look for it using Ctrl + F on the board, KiCad is unable to locate it, despite the component being placed on the PCB. Also, it can be found in the schematic editor.

EDIT2:
Okay, looks like a KiCad bug. These components are automatically marked as DNP by KiCad (not by me!) every time I update the PCB from the schematic. Why?
