Every accusation [is] a confession

That is indeed something which has been very visibly and very often proven, again and again and again, in the last couple of years.

I reckon it was always so, but we just forgot it during the period after WWII and the ressurging of the far-right.

Yeah, even cheap microcontrollers nowadays with support for clock functionality have an ultra low power mode were the only thing running is the clock crystal and the clock functionality which uses so little power that it can run for years from such a button battery.

The thing could do the same as my stupidly cheap alarm clock that has some batteries as power backup and just keep on counting time without displaying whilst mains power is down so that when mains power comes back up it still has the right time.

The extra $1 for the hardware needed for it is hardly going to matter next to the overal cost of anything but a stupidly cheap microwave.

I have a stupidly cheap microwave which I bought a few years ago (because I moved homes and the last one, a rental, included a microwave) and it has no clock.

In fact, it doesn’t even have the simplest of displays - the entire user interface is one analog rotary control for power and another for microwaving time - the latter rotating back by itself at a fixed speed - plus a bell that dings when the second control reaches the zero position.

If I want to know how long till a microwaving operation is finished I just look at the position of the second rotary control.

Sometimes simpler is better.

The “funny” thing is that anybody thinking that a mere 5 years ago would have been deemed a conspiracy nutter.

The definition of “crime” is pretty much controlled by a small number of people and it ain’t a crime if there’s no law against it.

Always remember that the mass murder of Jews and Roma in NAZI Germany wasn’t a crime because it was all legal. Similarly, Slavery wasn’t a crime in most of the World, and even today in many countries, such as the US some forms of it (for example using prisioners as forced labour) aren’t a crime.

We’ve been indoctrinated into in everyday speech conflate Legality with Morality (as its very useful for those who control lawmaking for the riff-raff to unthinkingly shun those deemed law-breakers and side with law-enforcers), so IMHO it’s a good idea to, once in a while, remind oneself that Laws are made by Humans, not Gods, and the reasons for Humans to make Laws as they are, are messy and the results themselves are often bad and easy to selectivelly interpret and abuse, something especially bad in ages like the one we live in when widespread political corruption is pretty much standard.

A common trope of this kind of “Press” in the UK was (no idea if still is, as I left Britain some years ago) the “many generations of the same family living on benefits (i.e social security)”, which was part to greater far-right picture they very purposefully painted of poor people as leeches.

Somebody actual went and researched it and found out that in the whole of Britain - home to over 40 million people - there was a grand total of 3 families with 3 generations living on benefits, 4 if you count the massive stippend the Royal family gets from the British state as “benefits”, though they’re filthy rich and don’t actually need it.

A common schitck of the far-right propaganda to selects a handful of people who are assholes and happen to be part of a social group said far-right wishes to slander and point them out as if they’re representative of whole group. They do this for everybody, not just immigrants and it’s not just them doing it: for example, notice how news coverage of demonstrations from some News organisations tends to focus of the handful of people destroying things rather than on the majority who are behaving peacefully, something incredibly common in pretty much the whole of the UK press, even the supposedly serious one.

A phospor absorbs the incoming light and then uses it as power for its own emission process, in a processes called “fluorescence” rather than “filtering”. It’s a very efficient process because almost all of the light coming in and absorbed by the fluorescent material ends up used to emit light.

A filter just cuts out (literally “filters out”) things other than what it’s supposed to let through. Filters just block stuff and thus cannot have on their output anything that’s not present on their input. Further, filtering can be very inefficient because everything that the filter doesn’t let through just ends up as waste heat.

Filtering doesn’t make any sense for light emitted by a diode junction because that specific light emission process emits light of a single wavelength - it’s a totally different process from incandescence and only emits photons whose energy exactly matches a specific quantum gap in that junction, hence all emitted photons have the exact same wavelength, thus there are no other wavelengths in the light emitted by the diode to filter out - thus if you filter out that specific wavelength, no light at all goes through the filter because there’s nothing else there.

Calling a phospor a “filter” is like calling a system with a solar panel connected to a green LED a “filter” - sure, the spectrum of the light coming in is not the same as that of the light going out, but that’s pretty much the only way the thing behaves the same as a filter - it does not share any of the other characteristics of a filter.

Anybody with a Physics or Engineering background will react the same as me when somebody describes a fluorescent material in front of a light source as “a filter” because per the scientific and engineering definitions “fluorescence” is not at all the same as “filtering”.

Whatever source you learned information about LED lights from, it’s really bad and shows no domain expertise, which is probably why you ended up with some things right in your explanations and others horribly wrong. If I was to guess, I would say that you “learned” it from AI, as getting the general stuff mostly right and the domain expertise details incredibly wrong is a common problem of AI.

That’s not even close to reality.

Read the material linked or just google it yourself.

Here are the LED drop voltages for reference.

LEDs aren’t just more efficient at those voltages, those are literally the difference in voltage between one side of the LED and the other side when in operation - if you feed it less than that the LED will simply not work. (Note that these drop voltages are not actually an absolute value but rather a very steep curve relative to current, but for simplification we can treat those as absolute ON/OFF voltage values).

Also the phosphor doesn’t filter light - rather it absorbs light and re-emits it in different wavelengths, the process being such that the emitted light covers a range of wavelengths even if the input light has a single wavelength as is the case for LEDs - so it’s not at all light manipulation by filtering and mixing light sources.

That said I went looking at how phosphor is used in LEDs nowadays and judging from this they don’t use red LEDs emitters at all nowadays, only blue and UV ones, and then chose a phosphor (which can be any substance, not just Phosphorous) whose emission range is towards the desired light range.

I’ve corrected my original post.

From what I read last time I properly looked into this (so, almost a decade ago when I was considering setting up a business importing LED lamps), the blue light emitting diode junction simply uses less power to emit the same amount of light.

Electrically speaking it’s no bigger or lesser a problem in terms of circuitry to have just blue diodes or blue + red diodes in there since they’re bundled in blocks of diodes in series (and then multiple blocks are in parallel) and the only thing that differs between those two kinds of junctions from a circuit point of view is the drop voltage of one kind of diode being different from that of the other (diode junctions done with different dopants have different drop voltages), something you take into account in the design stage when deciding how many LED diodes you use per block or what DC voltage will your 110v/220V AC input be converted to to feed those LED strings.

More specifically for LED light bulbs, the messy stuff in terms of electronics is the circuitry that converts the 220v/110v AC input into a lower voltage DC suitable for the LEDs whilst limiting the current (as diodes’ only ability to “limit” current is them burning out from overheating due to too much current), not the actual LEDs.

But I’ll put it even simpler: if the problem was indeed simplicity as you believe, then LED bulbs with only red LEDs would also be very common as they’re simpler than blue+red ones.

Personally I just go for warm white for places which should be cozy and cold white for places with a more utilitarian use.

Cold white LED light bulbs are actually more efficient, so I’ll even get more light out of the same power lamp making it easier to see what I’m doing (which is what you generally need lights for in an utilitarian use location).

As a side note, one of the reasons why cold white LED light bulbs are a thing is because they’re a bit more efficient than warmer light colors.

The reason is because they all just have 2 kinds of light emiting diode (LED) junctions inside - red and blue - plus a phosphorus layer on top that smooths those two perfect lightwave color peaks in the wavelength domain into a broader light spectrum, and the blue is more efficient than the red, so lamps with a higher proportion of blue emitters to red emitters - and which hence emit more light towards the blue end of the spectrum (i.e. a colder white) - will emit more light for the same power consuption than those with more red emitters and hence whose light is more towards the red side of the spectrum (i.e. a warmer white).

EDIT: So it turns out part of this which I learned 10 years ago is outdated. The efficiency thing is true but when I went looking for how phosphors (the layer between the LED emitters and the outside, which absorbs the single wavelength light from the LEDs and emits light with different wavelengths) prompted by the points made by another poster, from places like this it turns out that red LED emitters aren’t at all used anymore, only UV and blue (whose light the phosphor then converts into light with different spectrum distributions depending on the material of the phosphor). If you search for it a number of recent scientific papers pop up around various such materials.

As with everything, it real boils down to how pushy one is in their criticism.

If somebody who loved the thing goes looking for the opinion of others and finds critical opinions, well, though luck for them - they went looking for it and nobody else posting in what’s a public forum has any moral obligation from refraining to post a negative opinion, IMHO.

If however one is being relentlessy critical mid-film after the other person has made it clear that they don’t want to hear it, that’s being a selfish asshole in my view.

It’s perfectly possible to enjoy chewing gum for the brain even though one gets no nutritional value from it.

Being critical of a film is actually just having a critical opinion about it.

Sharing that opinion with others is something else: a way of deriving personal enjoyment or satisfaction from one’s critical position through sharing it with others.

As with everything else that requires multiple people, somebody deriving their enjoyment of something through others is absolutelly fine if said others are also doing so or at least if don’t really care either way, but not fine if one is negativelly affecting the enjoyment of others to get some enjoyment oneself.

So if you’re critical of something whilst somebody else is not and indulge your need to “share it with them right then and there” in a way that impedes their own enjoyment, then you’re being selfish and if you have even the slightest shred of consideration for others you should at the very least shut up until after they are done with their own enjoyment.

(That said, an after-film discussion between two people with opposite opinions about good it was can be thoroughly enjoyable for both. Ultimatelly it depends on the people involved)

Also to add to this, the life-cycle of a TV display is mismatched from the live-cycle of media playing hardware or just hardware for general computing: one needs to update the latter more often in order to keep up with things like new video codecs (as for performance those things are actually implemented in hardware) as well as more in general to be capable of running newer software with decent performance.

I’ve actually had a separate media box for my TV for over a decade and in my experience you go through 3 or 4 media boxes for every time you change TVs, partly because of new video codes coming out and partly because the computing hardware for those things is usually on the low-end so newer software won’t run as well. In fact I eventually settled down on having a generic Mini-PC with Linux and Kodi as my media box (which is pretty much the same to use in your living room as a dedicated media box since you can get a wireless remote for it, so no need for a keyboard or mouse to use it as media player) and it doubles down as a server on the background (remotely managed via ssh), something which wouldn’t at all be possible with computing hardware integrated in the TV.

In summary, having the computing stuff separate from the TV is cheaper and less frustrating (you don’t need to endure slow software after a few years because the hardware is part of an expensive TV that you don’t want to throw out), as well as giving you far more options to do whatever you want (lets just say that if your network connected media box is enshittified, it’s pretty cheap to replace it or even go the way I went and replace it with a system you fully control)

Only in “international university rankings” that treat essentially classes being given in the English language as about 1/3 of the score or as they call it, “easiness for international students”.

Or in other words, “for international students” they’re one of the best in the World, to a large extent because all lessons are in English so all else being the same, universities in English-speaking countries will always come above universities in non-English speaking countries because English is the main Lingua Franca at the moment.

Also a lot of the other quality metrics (such as number of published papers) actually measure research proeficiency rather than teaching quality, which whilst relevant for post-grads, isn’t quite as relevant for most students.

Whether if measured from the point of view of the main student community they serve rather than “international post-grad student” MIT is the best in the World, is unclear.

Curry is the greatest dish of English cuisine.

Like when the coach of a big sports team is interviewed on the half-time break of a game they’re losing, this guy will of course going to say they’re still going to win.

It would only be news if he confessed they were fucked.

In Portuguese from Portugal, one of the words for “queue” is “bicha”,

In Portuguese from Brasil, “bicha” is a slang word for homosexual and has nothing to do with queues.

So the common Portuguese expression to tell somebody one’s going to stand on a queue - “vou para a bicha” (literally “I’m going to the queue”) - has a whole different meaning for Brasilians.
