  • Clearly my point about this being like Junior Devs thinking they know better that the “lusers” whilst not knowing enough to understand the limits of their knowledge hit the mark and hurt.

    It’s hilarious that you think a background in game making (by the way, love that hypocrisy of yours of criticizing me for pointing out my background whilst you often do exactly the same on your posts) qualifies you to understand things like the error rates in the time and amplitude domains inherent to the sampling and quantization process which is Analog-to-Digital conversion “FAR” better than a Digital Systems Electronics Engineering Degree - you are literally the User from the point of view of a Digital Systems EE.

    Then the mention of Physics too was just delicious because I also have part of a Physics degree that I took before changing to EE half way in my degree, so I studied it at Uni level just about long enough to go all the way to Quantum Mechanics which is a teensy weensy bit more advanced than just “energy” (and then, funnily enough, a great deal of EE was also about “energy”).

    Oh, and by the way, if you think others will Shut The Fuck Up just because you tell them to, you’re in for a big disappointment.


  • But people do stop believing money has value, or more specifically, their trust in the value of money can go down - you all over the History in plenty of places that people’s trust in the value of money can break down.

    As somebody pointed out, if one person has all the money and nobody else has money, money has no value, so it’s logical to expect that between were we are now and that imaginary extreme point there will be a balance in the distribution of wealth were most people do lose trust in the value of money and the “wealth” anchored on merelly that value stops being deemed wealth.

    (That said, the wealthy generally move their wealth into property - as the saying goes “Buy Land: they ain’t making any more of it” - but even that is backed by people’s belief and society’s enforcement of property laws and the mega-wealthy wouldn’t be so if they had to actually protect themselves their “rights” on all that they own: the limits to wealth, when anchored down to concrete physical things that the “owners” have to defend are far far lower that the current limits on wealth based on nation-backed tokens of value and ownership)


  • And further on point 2, the limit would determined by all that people can produce as well as, on the minus side, the costs of keeping those people alive and producing.

    As it so happens, people will produce more under better conditions, so spending the least amount possible keeping those people alive doesn’t yield maximum profit - there is a sweet spot somewhere in the curve were the people’s productivity minus the costs of keeping them productive is at a peak - i.e. profit is maximum - and that’s not at the point were the people producing things are merelly surviving.

    Capitalism really is just a way of the elites trying to get society to that sweet spot of that curve - under Capitalism people are more productive than in overtly autocratic systems (or even further, outright slavery) were less is spent on people, they get less education and they have less freedom to (from the point of view of the elites) waste their time doing what they want rather than produce, and because people in a Capitalist society live a bit better, are a bit less unhappy and have something to lose unlike in the outright autocratic systems, they produce more for the elites and there is less risk of rebelions so it all adds up to more profit for the elites.

    As you might have noticed by now, optimizing for the sweet spot of “productivity minus costs with the riff-raff” isn’t the same as optimizing for the greatest good for the greatest number (the basic principle of the Left) since most people by a huge margin are the “riff-raff”, not the elites.


  • Nice content-free slogan.

    I’m not a Sound Engineer, I’m an Electronics Engineer - we’re the ones who had to find the right balance between fidelity, bit error rates, data rates and even circuit price when designing the digital audio sampling systems that capture from the analog world the digital data which the Sound Engineers use to work their magic: so I’m quite familiar with the limits of analog to digital conversion and that’s what I’m pointing out.

    As it so happens I also took Compression and Cryptography in my degree and am quite familiar with where the term “lossless” comes from, especially since I took that elective at the time when the first lossy compression algorithms were starting to come out (specifically wavelet encoding as used in JPEG and MPEG) so people had to start talking about “lossless” compression algorithms with regards to the kind of algorithms what until then had just been called compression algorithms (because until then there were no compression algorithms with loss since the idea of losing anything when compressing data was considered crazy until it turns out you could do it and save tons of space if it was for stuff like image and audio because of the limitations of human senses - essentially in the specific case of things meant to be received by human senses, if you could deceive the human senses then the loss was acceptable, whilst in a general data sense losing data in compression was unacceptable).

    My expertise is even higher up the Tech stack than the people who to me sound like Junior Devs making fun of lusers because they were using technical terms to mean something else, even while the Junior Devs themselves have yet to learn enough to understand the scope of usage and full implications for those technical terms (or the simple reality that non-Techies don’t have the same interpretation of technical terms as domain experts and instead interprete those things by analogy)


  • A PNG is indeed an imperfect representation of reality. Are you claiming that the lossness in the data domain of the compression algorithm in a PNG means its contents are a perfect representation of reality?!

    (Funnilly enough, the imperfections in the data contained on a PNG are noticeable for some and the lower the “sampling rate” - i.e. number of pixels, bits per pixel - the easier it is to spot, same as audio)

    As I’ve been trying to explain in my last posts, a non-Techie “audophile” when they claim FLAC is not lossless aren’t likely to be talking about it’s technical characteristics in the data domain (i.e. that data that you take out of a FLAC file is exactly the same as it goes in) but that its contents don’t sound the same as the original performance (or, most likely, a recording made via an entirelly analog pathway, such as in an LP).

    Is it really that hard to grasp the concept that the word “lossless” means different things for a Technical person with a background in digital audio processing and a non-Technical person who simply compares the results of a full analog recording and reproduction pathway with those of a digital one which include a FLAC file and spots the differences?

    This feels like me trying to explain to Junior Developers that the Users are indeed right and so are the Developers - they’re just reading different meanings for the same word and, no, you can’t expect non-Techie people to know the ins and outs of Technical terms and no they’re not lusers because of it. Maybe the “audiphile” was indeed wrong and hence “Confidently Incorrect”, but maybe he was just using lossless in a broader sense of “nothing lost” like a normal person does, whilst the other one was using the technical meaning of it (no data loss) so they were talking past each other - that snippet is too short to make a call on that.

    So yeah, I stand by my point that this is the kind of Dunning-Krugger shit junior techies put out before they learn that most people don’t have the very same strictly defined technical terms on their minds as the junior techies do.


  • They’re deemed “lossless” because there are no data losses - the word actually comes from the broader domain of data handling, specifically Compression were for certain things - like images, audio and video - there are compression algorithms that lose some information (lossy) and those which don’t (lossless), for example JPEG vs PNG.

    However data integrity is not at all what your average “audiophile” would be talking about when they say there are audio losses, so when commenting on what an non-techie “audiophile” wrote people here used that “losslessness” from the data domain to make claims in a context which is broader that merelly the area were the problem of data integrity applies and were it’s insuficient to disprove the claims of said “audiophile”.


  • My point being that unlike the misunderstanding (or maybe just mis-explanation) of many here, even a digital audio format which is technically named “lossless” still has losses compared to the analog original and there is no way around it (you can reduce the losses with a higher sampling rate and more bits per sample, but never eliminate it because the conversion to digital is a quantization of an infinite precision input).

    “Losslessness” in a digital audio stream is about the integrity of the digital data itself, not about the digital audio stream being a perfect reproduction of the original soundwaves. With my mobile phone I can produce at home a 16 bit PCM @ 44.7 kHz (same quality as a CD) recording of the ambient sounds and if I store it as an uncompressed raw PCM file (or a Wav file, which is the same data plus some headers for ease of use) it’s technically deemed “lossless” whilst being a shit reproduction of the ambient sounds at my place because the capture process distorted the signal (shitty shit small microphone) and lost information (the quantization by the ADC in the mobile phone, even if it’s a good one, which is doubtful).

    So maybe, just maybe, some “audiophiles” do notice the difference. I don’t really know for sure but I certainly won’t dismiss their point about the imperfect results of the end-to-process, with the argument that because after digitalization the digital audio data has been kept stored in a lossless format like FLAC or even raw PCM, then the whole thing is lossless.

    One of my backgrounds is Digital Systems in Electronics Engineering, which means I also got to learn (way back in the days of CDs) how the whole process end to end works and why, so most of the comments here talking about the full end-to-end audio capture and reproduction process (which is what a non-techie “audiophile” would be commenting about) not being lossy because the digital audio data handling is “lossless”, just sounds to me like the Dunning-Krugger Effect in action.

    People here are being confidently incorrect about the confident incorrection of some guy on the Internet, which is pretty ironic.

    PS: Note that with high enough sampling rates and bits per sample you can make it so precise that the quantization error is smaller that the actual noise in the original analog input, which de facto is equivalent to no losses in the amplitude domain and so far into the high frequencies in the time domain that no human could possibly hear it, and if the resulting data is stored in a lossless format you could claim that the end-to-end process is lossless (well, ish - the capture of the audio itself into an analog signal itself has distortions and introduces errors, as does the reproduction at the other end), but that’s something quite different from claiming that merely because the audio data is stored in a “lossless” format it yields a signal as good as the original.


  • Strictly speaking, as soon as an analog signal is quantized into digital samples there is loss, both in the amplitude domain (a value of infinite precision is turned into a value that must fit in a specific number of bits, hence of finited precision) and on the time domain (digitalization samples the analog input at specific time intervals, whilst the analog input itself is a continuous wave).

    That said, whether that is noticeable if the sampling rate and bits per sample are high enough is a whole different thing.

    Ultra high frequency sounds might be missing or mangled at a 44.7 kHz sampling rather (a pretty standard one and used in CDs) but that should only be noticeable to people who can hear sounds above 22.35kHz (who are rare since people usually only hear sounds up to around 20kHz, the oldest the person the worse it gets) and maybe a sharp ear can spot the error in sampling at 24 bit, even though its miniscule (1/2^24 of the sampling range assuming the sampling has a linear distribution of values) but its quite unlikely.

    That said, some kinds of trickery and processing used to make “more sound” (in the sense of how most people perceive the sound quality rather than strictly measured in Phsysics terms) fit in fewer bits or fewer samples per second in a way that most people don’t notice might be noticeable for some people.

    Remember most of what we use now is anchored in work done way back when every byte counted, so a lot of the choices were dictated by things like “fit an LP as unencoded audio files - quite luterallyplain PCM, same as in Wav files - on the available data space of a CD” so it’s not going to be ultra high quality fit for the people at the upper ends of human sound perception.

    All this to say that FLAC encoded audio files do have losses versus analog, not because of the encoding itself but because Analog to Digital conversion is by its own nature a process were precision is lost even if done without any extra audio or data handling process that might distort the audio samples even further, plus generally the whole thing is done at sampling rates and data precision’s fit for the average human rather than people at the upper end of the sound perception range.



  • The Guardian absolutely is capitalist (neoliberal, even). Just go check back on their campaign against Corbyn (a leftwinger who won the Labour Party leadership from the New Labpour neoliberals some years ago) which included such memorable pieces of slander like calling a Jewish Holocaust Survivor an anti-semite because of him in a conference about Palestine comparing some of the actions of the government of Israel with those of the Nazis, this done in order to slander Corbyn by association since he was in the same panel in that conference.

    Also you can merely go back a few months to see how The Guardian supported Israel well into their Genocide (though they seem to have stop doing it quite as eagerly in the last few months).

    Last but not least they very openly support in British elections the Liberal Democrats (who are neoliberals) and the New Labour faction of the Labour Party (also neoliberals) and very often have pro-privatisation articles on UK subjects and are never for bringing things back into public ownership even when privatisation has failed miserable to give better services or lower prices.

    I lived in Britain for over a decade and read The Guardian for most of it, so maybe The Guardian’s political slant is clearer for those familiar with British Politics.

    I do agree on The Intercept and Democracy Now! though.

    Can’t really speak for the others with any knowledge.



  • Whilst I would be wary of saying AirBnB is the main cause (more likely it’s a big one but not the only one), keep in mind that when realestate prices go up in major cities, that pushes out people who go to cheaper places, pushing prices up in those places which in turn might push some out from those places and into even cheaper places.

    So housing bubbles centered in main cities do naturally spread out from there to places were the original causes of the bubble are not present.


  • In my own Portugal, which is a very turistic country and also towards the bottom of the GDP-per-capita scale in the EU, things that would likely work very well would also be:

    • Crack down on AirBnB
    • Forbid ownership for non-residents.

    Portugal currently has a massive house inflation problem (extra massive, because of how low average incomes are here) and a lot of it has to do with residential housing being removed from the housing market and turned into short term turist lets (for example, over 10% of housing in Lisbon has been turned into AirBnB lets) and foreign investors (not just big companies but also individuals, such as well off pensioneers from places like France) pulling prices up by being far less price sensitive than the locals as they’re buying residential housing as investments having far more money available than the average Portuguese.

    Having lived in both Britain and Portugal during housing bubbles, what I’ve observed was that the politicians themselves purposefully inflate those bubbles, partly because they themselves are part of the upper middle class or even above (especially in the UK) who can afford to and have Realestate “investments” and hence stand to gain personally (as do their mates) from Realestate prices going up and partly because the way Official GDP (which is supposedly the Real GDP, which has Inflation effects removed) is calculated nowadays means that house price inflation appears as GDP “growth” since the effects of house price increases come in via the “inputted rent” mechanism but the Inflation Indexes used to create that GDP do not include house price inflation, so by sacrificing the lives of many if not most people in the country (especially the young, for example the average age for them to leave their parent’s home in Portugal is now above 34 years old and at this point half of all University graduates leave the country as soon as they graduate) they both enrich themselves and can harp in the news all about how they made the GDP go up.

    All this has knock on effects on the rest of the Economy, from the braindrain as highly educated young adults leave and the even faster population aging as people can’t afford to have kids, to shops closing because most people have less money left over after paying rent or mortgage so spend less, plus the commercial realestate market is also in a bubble so shops too suffer from higher rents. However all this is slow to fully manifest itself plus those who bought their houses before when they were cheaper don’t feel directly like the rest, and they generally don’t really mentally link the more visible effects (such as more and more empty storefronts) to realestate inflation, much less do more complex analysis of predictable effects, such as how the braindrain and fall in birthrates will impact their pensions in a decade or two.
