Its because "reality has a surprising amount of detail". It is actually the rare occurrence where a simple solution solves a complex problem. I link an excellent article that has been posted on HN multiple times, that explains exactly this.[1] (not mine)
Yes off course, but with the obvious disadvantage that you lose resolution for every filter you add. Then you say let's just increase the pixel count, which means smaller pixel pitch. But then you lose low light sensitivity, have to decrease your lens f/#, so more expensive lenses etc... Which is why it isn't done for commercially / mass market sensors.
You also need to take into account your manufacturing precision you can achieve with fabricating the lenses, how accurately you can position the lenses relative to the work piece etc. From my cursory reading of the paper it assumes perfect lenses and positioning, and only simulates the alignment procedure. Still, a worthy paper, but as others have mentioned, not much different than the methods used for optics alignment.
That's because IT security reports to the C level, and their KPI's are concerned with security and vulnerabilities, but not the performance or effectiveness of the personnel.
So every time, if there is a choice, security will be prioritized at the cost of personnel performance / effectiveness. And this is how big corporations become less and less effective to the point where the average employee rarely has a productive day.
Similar reason why the earth north pole is actually a magnetic south pole :) It was decided by convention / definition.
For those whom it isn't clear what I mean. Compass magnet's north poles point north, which is only possible if the earth's north pole is magnetically a south pole.
There is a joke, that in order to facilitate such a change, it should be done in more manageable steps. So on day 1, only the motorcycles switch over to the other side of driving, on day 2 the motor vehicles, and on day 3 the trucks and busses switches over...
You can either wire a relay yourself, your smart plug just switches the relay, and you can size the relay according to your needs.
Or use smart switches made for geysers. Something like the sonoff pow3 can handle up to 5.5kW. Since it is just a relay inside I am pretty sure it can handle inductive loads fine.
Doesn't the power wall include an inverter that allows for hot switching between battery and main line supply? That would explain a large part of the price disrepancy.
İyi şanslar, but also used regularly is kolay gelsin, which means let it come easy, or go easy, there is no direct translation. Then there is also hayırlısı, which means what will be will be, in my experience used sarcastically / raising you shoulders when everything is f*cked, as is common these days in Turkey.
