in bash if it happens, it often means i have something wrong in most recent closed loop, which may or may not have closed prorperly, somethign similar with python.

i know this solution, but many problems are there, what if it is in a ceiling fixture, or enclosed in something such that i can not know the temp (hot or cold), then i can still observe luminosity changes. if you feel your eyes do a bad job, get a camera properly color and temp caliberated, and just focus on filament (now auto exposure or temperature adjustment).

tl:dr i am still trying to poke holes in this thermocol wall of defence.

After reading the incandescent bulb solution, and problems regarding touching the bulb, i would switch first switch on for a appreciably long time, such that bulb has hit maximum luminousity (they heat up as they run, the hotter they get, the brighter they are), then turn switch off, and turn second switch on and quicky run to other room. we are trying to observe change in luminousity as time elapses. if it reduces, it was first (we ran it for a long time, there would be some residual glow, from my irl observations from when i was small suggest roughly 1 min period where i can still tell, but bulb wattage, contrat with background and distance matter). if increasing or max luminous, then second, if nothing then third.

but it was a stupid question. my naive guess was it can not be done, because with just 1 binary observation, you can not tell from 3 switches (you need atleast 2, which the solution assumes as temp and light state, i substitute heat with light state in transition). but still stupid. my natural assumption was leds, even when i head incandascent bulbs in my house somewhere for nearly half of my life. it is also stupid, because when you allow me to do something i was mentioned in question to do, i could just bend my way to do anything. like punch/drill through wall, or hack surveillance systems, or just pull out my handy multimeter that i always have on me, open switch box and see which switch is live, which is dead, or see voltage/current/wattage change across the loop, or measure resistance and guess what thing is there, or like blackmail the interviewer to extract the answer.

i concede, you are too chad for me to even be in same plane of existence.

I always knew I am not a real programmer

voronois space filling

they are different things, wget and curl do not have many overlapping use cases other than downloading stuff over http

thankyou for encouraging. I will try out a bit. next thing to decide is topic to begin with, and how/where it would happen.

Imagine you are the one deciding, what medium would you prefer?

What i have been thinking is essentially a online meeting, like jitsi meet, which may be simultaneously casted online, or just recorded, and uploaded afterwards. people in meet would be able to ask, and hence it would be interactive. Whenever i have done courses, i have had like a billion questions, and if i do not ask, i do not understand, so i would not want anyone else to not be able to ask too. live chat is also interactive, but there is always a delay, and writing your doubts, is sometimes hard (you sometimes are so confused you do not know what to ask), so meeting helps with that.

in any case, if you need any help (for example course work or books), feel free to message me.
