You’re still being reductive. An indicator LED can work without any part of it more than 10 °C above ambient temperature. No incandescent light bulb can achieve this.

And yes, there are indeed lighting systems that use many low-power LED chips spread over a large area, none of which get hot even by human standards. These cost a lot of money but last extremely long.

Power density of the Sun is approximately 276.5 W/m³. That’s counterintuitively little. A classic LED 3mm plastic package has the volume of less than 40 mm³ and some white ones can handle about 100 mW without a heatsink. Even leaving space for connections and airflow, you can easily overpower the Sun by volume by orders of magnitude.

A fun article mentioning that 276.5 W/m³ is about a reptile’s metabolism (and they famously produce little body heat): https://what-if.xkcd.com/148/

Basically, as this Stack Exchange discussion correctly states, human intuition is quite useless when thinking about things orders of magnitude outside our experience.

Meanwhile, you say “hot” because that’s what your finger felt. Not really convincing of your ability to think in cosmic proportions.

I’m trying to get you to stop reducing temperature scale to “anything over 60 °C is hot” because it’s not useful: a clearer distinction should be made between something that regularly causes house fires and something I unscrew while it’s on to put under my blanket when my toes are cold. Human perception of temperature (classic 0-100 °F) just does not allow comparing things an order of magnitude higher (in Kelvin ofc). There’s also more to heat, its effects and how it’s perceived than a single measurement of temperature: thermal mass, conductivity, color (exchange via radiation differs between black and white bodies) etc.

Also, it’s indeed ad hominem but you did choose the username yourself.

Nah, too cold. It stopped moving and the computer can’t generate any more random numbers to pick from the LLM’s weighted suggestions. Similarly, some LLMs have a setting called “heat”: too cold and the output is repetitive, unimaginative and overly copying input (like sentences written by first autocomplete suggestions), too hot and it is chaos: 98% nonsense, 1% repeat of input, 1% something useful.

Username checks out

Boiling hot, as opposed to METAL-MELTING REMOTELY-SCORCHING HELL-BLAZING INFERNO

How long before you admit there is a point to calling them “cold light sources” because their color temperature is higher than what black body radiation (incandesce) can do?

From a human’s standpoint, we say they’re “hot”. The fact that humans can’t handle 150 °C nor 2700 °C does not mean there’s no difference between the temperature of a sausage fresh off the grill and magma. (Yes, by the time it gets to the surface, lava is too cold)

LED chips can’t get above 150 °C or they fail. So high-power LED lights need appropriate cooling. And the heatsink is big and thermally conductive, making it feel hotter to the touch than it is (it delivers more heat to your finger over time). Meanwhile, the glass of some bulbs can exceed 300 °C but cools down to safe levels in a minute (or less if you touch it with something) because it’s thin.

Also, 150 °C (420 K) objects do radiate heat as black-body radiation but not that much, also it’s far-IR so only detectable with thermal cameras. Meanwhile, a light bulb’s filament is 2700 K (3000 K in halogen ones) and the Sun’s surface is 6000 K, and both produce copious amounts of near-IR light that largely contributes to the heat felt on one’s skin when illuminated (although the visible light does too).

Yes! And I’d much rather haz ICAN than ICANN. They are OK with numbers but their names department is run by a bunch of clowns.

• - “Can I uze a word plz?” - “Submit an application, we take them every 10+ years for $300K each and you’ll get a reply in 12-18 months”
• - “You’re deprecating .io? What about my domain?” - “Get fucked”

I’m referencing “ICANN haz .meow?”, a slogan by the .meow campain (Fully funded now!)

Not all places have cold water during summer (did the greedy water company already run a heat exchange there?)

This would work but don’t use a conventional central heating radiator system: moisture would condense on the radiators and pipes, potentially causing wet floors and walls, and eventually mold. A radiator that deals with moisture well is an indoor AC unit, plus it has a fan, thermostat and remote control, and presumably they’re cheap to get when the more complicated outdoor unit fails. Just pump water through the coolant pipes! The water mains pressure is probably enough. (Don’t get an overly smart one or it will complain about lack of communication with the outdoor unit. Or hack it if you’re good at that.)

Alternatively, an air-to-water heat exchanger (heat pump whose condenser is submerged and evaporator is a conventional indoor AC unit) is way more practical. With cold water, it will use very little electricity and has all the convenience of AC. The output water can be used as preheated feed into your boiler.

Landing on a “leader board” is easier in German. Just look how cheaply you can acquire a “Leiterplatte” and jump on it.

So do CDs. 💿 If you have a player with a see-through lid, you can see the disc rotate around 2.5 times slower on the last track of a near-74/80-minute disc as opposed to the first. This might not apply with modern (2000+) and/or portable ones with cache (ESP) − MP3 support is a good clue it has the advanced electronics for that. And yes, CDs’ track starts at the center to enable short-play, smaller disks of any diameter between 5 and 12 cm (although slot-loading players only have cutouts for the two standard sizes).

Players regulate the motor speed based on the data clock (and burners too: there is a pre-recorded “timing” signal even on blank CD-Rs) so technically, a constant-angular-velocity CD could be pressed and played on most players, just with no real benefits. The extra linear velocity at the edge would require increased laser power (or less than 1x speed) when burning, and vinyl killers (in the unlikely case they ever make a CD one) won’t keep up.
