As the distance increase between two surfaces, the capacitance diminishes and the voltage between the two increase, so that C=QV is always true.
The resonant frequency is determined by the impedence, i.e. capacitive and inductive impedence.
You can't affect inductive impedance of the antenna because you are not a coil and do not emit EMR. But you can change the capacitance between you and the antenna by moving closer or further away.
How do you think you are changing the resonant frequency? By modifying it's capacitive impedence, i.e. creating a capacitor with yourself and the antenna.
And you know what we call the difference of electric potential between two points? Voltage.
When you say that capacitance is geometry, you are right. The distance between two objects, be it you and an antenna or two planks of wood, affect the capacitive impedance.
To further your point, theorically, there is a voltage potential between any two objects. That's the capacitance. Better conductor, for the same surface area, create a bigger potential.
So when you tune/detune a signal with your presence near the antenna, it is because you are close enough to the antenna that the potential between you and the antenna affects the filter of the signal.
With all the layoffs we see, that is fucking bullshit. The workers get shafted even when they are doing a good job because of dumb fucks c-suite gambling the company on bullshit technology, or simple cutting costs for the shareholders.
That’s the wrong message that you are getting out of that article. The problem is that more and more people need their parents help to get in the market.
That trend means that at one point, help from parents will be obligatory to buy a first house, closing the market to anyone that doesn’t have rich parents.
You can setup a VPS between the internet and your home network to limit the exposition of your home network. When a client pings yourdomain.com, it sees the ip of the VPS and not the IP of your home network.
Otherwise, a VPN + home CA server will make your home network accessible and encrypted as well
I am new at this, but from my understanding, if you want to not expose anything to internet, you would need to create your own CA server to create your own certificates and have the necessary encryption certs for your own https on your home lab.
