Worry not, some of what’s perfectly fine nowadays will eventually be forbidden because how harmful it is for people, from micro-plastics that are being found even in men’s gonads to the excessive amounts of nitrous oxides emitted by diesel engine that kill over ten thousand people per year in Europe alone.
We probably still breathe and eat a lot of highly carcinogenic shit, just different shit from back in the days when asbestos was considered a great fire-proof substance.

IMHO, the almost idolatry of the Constitution in the US meant that a what’s essentially a Prototype of Modern Democracy kept getting used without a systemic update for too long and was essentially relying on everybody being a gentleman to work.
Personally the whole part were the Political Pillar being in charge of nominating the top of the Judicial Pillar - the Supreme Court Judges - even though in Democracy those Pillars are supposed to be independent, always felt like a major weakness in the face of Authoritarian encroaching, as did the First Past The Post voting system.
That’s the point I’m trying to make: the flaws in the American system are systemic, making it more easy from autoritarians (not just Trump’s Fascists but also the Oligarchy that stands behind both the Republicans and the Democrats) to control it.
The main difference with the Fascists is how brazen then are in doing so, which the other bunch would be far more discrete (hence which the Prison population in the US was already so large under the “other” political party of the US Duopoly system).

suppress wages in prison workshops, and exempt them from minimum wage
And how is that in any way form or shape a good thing?
That shit is just Indentured Servitude with extra steps.
It seems to me (not at American) that the intention to exploit people who have no other choice was there from the start. Create a structure were you can get cheap/free labor of people who have been deemed by others to be LABEL (in this case, a felon) and deprived of their freedom and you always end up with more and more people being given LABEL and deprived of their freedom so that the can be used as cheap/free labor.
The United States has long been the nation in the World with the highest percentage of people in prison.
The well was poisoned from the very start.

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 - it has one analog rotary control for power and another for microwaving time, the latter rotating back by itself at a fixed speed.
Sometimes simpler is better.
- Comment on London stabbing rates vs X posts about London crime 1 week ago:
The definition of “crime” is pretty much controlled by a small number of people: 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.

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.

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 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 sence 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, which only emits photons whose energy exactly matches a specific quantum gap in that junction, hence all have the exact same wavelength so there are no other wavelengths to filter out and if you filter out that specific wavelength no light at all goes through 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 “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.

- Comment on lightbulbs 1 week ago:
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.
- Comment on lightbulbs 1 week ago:
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.
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.
- Comment on lightbulbs 1 week ago:
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).
- Comment on lightbulbs 1 week ago:
As a side note, the reason 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).

Explanation
Mullvad just gives your machine an IP address from a range reserved for internal networks and which is not valid to use as a public IP on the internet, and then does NAT translation like your home router does.
NAT translation just uses a gateway/router as a front on the Internet (thus, with a public IP address) for a bunch of machines with non-public IP addresses: if a connection comes from an inside machine to a machine on the internet it just replaces the source IP & port address on the outbound connection with its own public IP and available port so that if the external internet machine connects back, it knows which internal machine is supposed to receive that connection.
So if you machine on the internal network side connects out to another machine on the Internet, at least for a while (until it purges than information from memory because it’s not being used) the NAT server will treat connections from that machine to it (remember, the NAT server is the one with a valid public IP address) as actually meant to go to your machine.
However if a connection comes from a machine outside which your own machine has never before connected to (which is the case when you start seeding and you machine ends up in the list of seeders of a torrent), since your machine never connected to that one in the first place the NAT server doesn’t know which internal machine that connection is supposed to go to, so it never gets to that machine.
The way to have your machine reachable by any random external machine when you’re using NAT is called Port Forwarding which is a mechanism to reserver one of the IP ports on the NAT server so that any connection to that port is always forwarded to a specific internal machine.
Mullvad doesn’t support port forwarding, hence the problems with seeding.
TL;DR What you can do
After downloading a torrent, leave it seeding. Since during the download stage your machine connected with pretty much all machines in the swarm (even if just to check what they have available) the NAT server has them associated with your machine in its list so that if any of those machines tries to connected back the connection gets forwarded to your machine, hence requests from any of those machines to download blocks come through and get served by your machine.
However new machines that join the swarm won’t be able to reach your machine because Mullvad’s NAT server doesn’t know them hence doesn’t know it should forward their connections to your machine.
This is the same reason why if you just start seeding from scratch nothing ever manages to connect to your machine - none of the machines outside trying to reach yours is in the list that the NAT server has of machines your own has reached earlier so their connections to the public IP of the server don’t get forwarded to your machine.
In my experience just leaving it seeding after downloading is enough to have at least a 2:1 seed to download ratio in most torrents, so if your objective is to give back to the community as much or more than you take, that’s enough IMHO.
If however you just want to seed for other reasons, then you won’t be able to do it with Mullvad. Either get a VPN provider that supports port foward or rent a seedbox and use that.

- Comment on We all took foreign languages in school and none of us can actually speak those languages 4 weeks ago:
Yeah, ok, that makes sense.
I suppose the only part that my post adds is that in my experience for native English-speakers the tendency to learn the language of the country they live in is less than for non-native English speakers who are also not locals, because - thanks to English being the global lingua franca, almost everybody finds it easy to switch to English when confronted with a person who doesn’t speak their local language well but does speak English well, which makes it a lot harder in the early stage to learn the language of the locals (you need to be really assertive about wanting to try to speak the local language).
Certainly that was my experience in most of Europe.
- Comment on We all took foreign languages in school and none of us can actually speak those languages 4 weeks ago:
If you are from the US and stay there, English is the global Lingua Franca, the local Lingua Franca, the language of the country you live in and your mother tongue, and thus you will likely never learn a second language to fluency levels.
Well, sorta.
In my experience with British colleagues when living in The Netherlands (were you can definitelly get away with speaking only English), whilst some of them never really became fluent in Dutch, others would become fluent in it.
You see, even with English being a lingua franca, many if not most of the locals (how many depends on the country and even area of the country - for example you’re better of speaking broken German with the locals in Berlin than English) are actually more comfortable if you speak their language, which make your life easier. Also the authorities will often only communicated in the local language (in The Netherlands the central authorities would actually send you documents in English, but for example the local city hall did everything in Dutch).
That said, if you’re an English speaker you can definitelly get away with not learning another language even when living elsewhere in Europe plus I’ve observed that in the early stages of learning the local language often when a native English speaker tried to speak in the local language the locals would switch to English, which for me (a native Portuguse speaker) was less likely, probably because the locals could tell from a person’s accent if they came from an English-speaking country hence they for sure knew English whilst with me even if they recognized my accent they couldn’t be sure that I spoke English.
- Comment on We all took foreign languages in school and none of us can actually speak those languages 4 weeks ago:
I am from Portugal - which is a very peripheral region in Europe, bordering only Spain - but do speak several European languages, and one of my most interesting experiences in that sense you describe was in a train in Austria on my way to a ski resort, an intercity train which was coming from a city in Germany on its way to a city in Switzerland just making its way up the Austrian-Alps valleys, and were I happened to sit across from two guys, one Austrian and one French, and we stroke up a conversation.
So it turns out the French guy was a surf promoter, who actually would often go to Ericeira in Portugal (were at a certain time in the year there are some of the largest tube waves in the World, so once it was “discovered” it became a bit of a Surf Meca) only he didnt spoke Portuguese, but he did spoke Spanish.
So what followed of a bit over an hour was a conversation floating from language to language, as we tended to go at it in French and Spanish but would switch to German to include the Austrian guy and if German wasn’t enough (my German is only passable) we would switch to English since the Austrian guy also spoke it, and then at one point we found out we could both speak some Italian so we both switched to it for a bit, just because we could.
For me, who am from a very peripheral country in Europe, this was the single greatest “multicultural Europe” experience I ever had.
That said, I lived in other European countries than just my homeland and in my experience this kind of thing is more likely in places which are in the middle of Europe near a couple of borders and not at all in countries which only border one or two other countries.
- Comment on We all took foreign languages in school and none of us can actually speak those languages 4 weeks ago:
In my experience when I lived in Holland, compared to me my friends and colleagues from English-speaking countries had the additional problems in trying to learn Dutch that people would tend to switch to English when they heard them speak in Dutch (probably because they picked up from their accent that they were native English speakers) plus their own fallback when they had trouble expressing themselves or understanding others in Dutch was the “lowest energy” language of all - their native one.
Meanwhile me - being a native Portuguese speaker - suffered a lot less from the “Dutch people switching to English when faced with my crap Dutch language skills” early on problem (probably because from my accent they couldn’t be sure that I actually spoke English and they themselves did not speak Portuguese) and my fallback language when my Dutch skills weren’t sufficient was just a different foreign language.
So some of my British colleagues over there who had lived there for almost 20 years still spoke only barelly passable Dutch whilst I powered through in about 5 years from zero to the level of Dutch being maybe my second best foreign language, and it would’ve been faster if I didn’t mostly work in English-speaking environments (the leap in progression when I actually ended up in a work environment were the working language was Dutch was amazing, though keeping up was a massive headache during the first 3 or 4 months).
That said, some other of my British colleagues did speak good Dutch, so really trying hard and persisting worked for them too (an interesting trick was when a Dutch person switched to English on you, just keeping on speaking in Dutch).
- Comment on We all took foreign languages in school and none of us can actually speak those languages 4 weeks ago:
Speak for yourself: I built on learning 2 foreign languages in highschool to end up speaking 7 languages (granted, only about 5 at a level of easilly maintaining a conversation).
The more languages you learn and the more you use them, the easier it is to add more languages to the pile.
Also, at least for European languages, because they generally are related, learning a few helps with learning others: for example, my speaking Dutch helped me learn German and there are even weird effect like me being able to pick up words in Norwegian because they’re similar to the same words in the other two or when somebody gave us an example of Welsh in a trip to Wales I actually figured out he was counting to 10, both because some numbers were similar to the same numbers in other languages plus there is a specific rythm in counting to 10.
As I see it, the more languages you know, the more “hooks” you have to pick stuff up in other languages.
That said, you have to actually try and practice them: for example, most of my French language was learned in highschool, so when I went to France or even Quebec in Canada I tried to as much as possible speak French, which helps with retaining and even expanding it so my French Language skills are much better now than when I originally learned it in a school environment.

Generally the more money that depends on their systems being functional without errors or interruptions, the more an industry is willing to pay for devs.
However in addition to that there is also the supply-demand effect: in demand specialists in rare areas get paid more than people doing the kind of work for which there are a lot more experiences professionals around.
3D graphics programmers would benefit from the second effect but not as much the first.
As a comparison, for example Quants (who program complex mathematical models used in asset valuation software for complex assets such as derivatives) in Investment Banking in London - thus who gain from both effects - about a decade ago had salaries of around £300k per year.
