I’d add to that that classical music was made at a time recording and listening whatever you want, whenever and wherever, wasn’t a thing.
Many pieces were intended as a whole, and optimised for specific settings.
I’ve long thought I wasn’t an opera person. I listened to pieces of some on my iPod, or on the tv in music class in school. Then, years later, some friend told me he had extra tickets for the opera.
It hit very, very differently. It is likely the experiences I had gone through since school helped the opera’s theme and songs resonate with me. But I’m pretty sure listening and witnessing it, from beginning to end, in a room carefully crafted for this specific purpose and left little room for distractions contributed immensely.
This is a surprisingly taxing change. There's a difference between giving free eggs to your neighbours, and giving free eggs to the Holiday Inn across town.
There’s one business book I’ve actually enjoyed reading and somehow learned more from years after reading it than while reading it: Business Adventures.
It’s a bit silly, doesn’t pretend to be a guide, provide any wise advice of any sort, and certainly not to have the one grandiose radical new idea that will solve all your problems™.
We were a bit late when we discovered wireless USB had been a thing. Still, we managed to find one pair of emitter and receiver that also transmitted HDMI, power the "receiver" side with a battery, in a backpack, and hook it up with another power bank to an Oculus DK1.
Unexpectedly, battery time was never an issue. The WUSB chip in the receiver would overheat long before that and start throttling, leading to jittery head tracking.
Turned out, it was a widespread issue with that WUSB chip.
Yes, it will move the hot air, but typically the temperature of the chip is substantially higher than the ambient air inside the enclosure (be it a backpack or a laptop shell or anything else.) Furthermore, even if the backpack is 100% sealed, by raising its temperature you significantly increase the amount of heat that the backpack rejects.
A quick Google says that the Oculus DK1 used ~3W, and you can easily find a fan that uses a fraction of a watt to move a reasonable amount of air, so this would probably have worked out.
Fans reduce sensible heat because humans have evaporative cooling.
A backpack is pretty much a closed system and chips use convective cooling.
Adding a fan won’t create a positivee pressure gradient between the backpack and outside world but will add 3 or more watts of heat to the closed system.
Did you even read my comment? I have designed cooling systems professionally and I can assure you that is how things work :) Not trying to be rude, but your comment is incorrect in several ways.
I'll make this very simple: The hot chip is warmer than the ambient air because the rate of heat transfer from the chip to the air is low. A fan will increase the rate of heat transfer, thus decreasing the temperature of the chip and increasing the temperature of the air in the backpack. It will also increase the rate of heat transfer from the backpack air to the backpack, which will increase the rate of heat transfer from the backpack to the environment.
Notably, the fan would help even if the backpack was a magic closed system (which it is not; put a 100W computer and a 1kWh battery into it, open ten hours later, and you will not have anywhere near 1kWh of heat.) But why would it help in a closed system? Because the chip does not care about the total energy in the system, the chip cares about the peak chip temperature. The chip will always be the hottest thing in the backpack, but the delta in temperature between the chip and the air can be quite large. Indeed, in practice, for "natural convection" (no fan), this dT between the chip and the air is considerable. When you add a fan ("forced convection") you shrink that dT substantially.
Thank you. I learned something fundamental from your comment that I did not know prior. Well, maybe I did, but how I think about it makes it harder to reason about.
Whatever, it is easier to see for me now. Lol
Seeing the benefit of the fan in terms of increased heat transfer to everything the air touches is easy. Full stop.
Heat is a fascinating thing. I can really recommend trying to visualize it and "playing around" with it in your daily life to get a stronger intuition for things. Pay attention to the thermal conductivity of the things around you and how that "feels": aluminum or copper extremely high, other metals high, plastics and woods low, fabrics and foams very low. Notice how evaporating water is very powerful at cooling things down, and how condensing water can warm things up. Notice how a small hot object cools slowly but a larger one can reject the same amount of heat very fast. Inspect the back of your fridge, or the inside of an A/C, and understand what's going on and where the energy is.
Same thing for fans in a desktop case, a laptop case, or on a graphics card. They cool down the CPU / GPU / desk to case even when said computer is in a closed room.
Hadn’t thought of it this way, but it’s kind of obvious when you think of it. Would most likely have helped.
I had some fun playing around with memes and LLMs, and although I doubt there's anything remarkable to take away from it, maybe some of you will find it amusing too.
Those conflicts (and there was a more recent one, in UK, during the 1980s), are with folks that have difficult, low-skill, low-pay, blue-collar jobs that can be filled by many people.
I doubt that you could find similar stuff about high-skill, highly-paid employees, such as engineers. I think that, even in the days when cavalry was being used against striking miners, the white-collar workers were being treated fairly well.
Maybe it has been worse for them, but I’m not so sure.
Ah you're right! I don't know why I forgot Saint-Lazare.
I checked the link in the sibling comment[0] and just found out that "Gare Paris Bercy Bourgogne - Pays d'Auvergne" is a thing that exists. Never heard of it before.
So all in all, from a Frenchperson's perspective there are 7 "gares" (train stations) in Paris.
