  • Whilst I agree with you in everthing but the first 2 words of your post, I think this is yet another “look at this cool gadget” post that overhypes something, and that is a kind of spam we get a bit of around here, even if nowhere near the levels of the Elon crap or even just US politics.

    This is especially frustratingfor people who, like me, looked at the diagram they link from their article and found out it’s pretty much the same as a run of the mill breadboard power adaptor with a USB-C connector and a slightly better design than the cheap chinese ones, rather than something trully supporting USB-PD (this thing doesn’t even support the basic USB 1.0 negotiation needed to get more than 150mA when connecting to a proper USB host).

    That the article then mentions a “crowdfunding campaign” for something that a junior EE can design with a bit of datasheet digging, carries a bit of a stink of a cash-grab, so seeing it as spam is understandable.


  • If you look at the circuit diagram in their documentation linked from that article, that thing doesn’t even support USB-PD or even just the USB 1.0 device side of the negotiation to increase the current limit from the default (150mA in USB 3) to high (900mA in USB 3). It will look like it works fine if you connect it to a dumb USB power supply (because those thing don’t really do any USB protocol stuff, just dumbly supply power over USB connectors up to the power source’s limit) but if you connect it to, say, a PC USB port (which does implement the USB host side of the USB protocol), your circuit on the breadboard that worked fine when using a dumb USB power supply with that breadboard adaptor might not work because the current it needs exceeds that default 150mA limit for devices that haven’t done USB negotiation (worse if it’s a USB 2.0 port, as the limit is lower for those)

    This thing is basically the same as the chinese power breadboard adaptors you can get in places like Aliexpress, but with a USB-C connector instead of a Type-A, micro-USB or mini-USB one, plus its better designed (it has a proper Buck Converter instead of a cheap Votage Regulator, plus better power supply filtering and a polyfuse to protect it and the host from current overdraws).

    The headline and the article seriously exagerate this “achievement”.


  • TL;DR - It’s a nice and pretty run of the mill breadboard power adaptor which happens to support USB-C connectors, but the article and its title insanely oversell the thing.

    This is not exact as amazing an achievement as the headline implies since the necessary stuff to talk the to the USB PD host upstream is already integrated so you just need to get a chip that does it (and even without it, you’ll get 150mA @ 5V by default out of the USB 3 host upstream and up to 900mA with some pretty basic USB negotiation in a protocol that dates from USB 1.0 and for which there have long been integrated solutions for both the device and the host sides).

    Further, the converting of those 5V to 3.3V just requires a buck converter or even just a voltage regulator (though this latter option is less efficient), for which there are already lots of integrated solutions available for peanuts and where the entire circuit block needed to support them is detailed in the datasheet for that converter.

    Looking at the circuit diagram for this (linked to from the article), they’re not even doing the USB PD negotiation or any kind of USB 1.0 negotiation, so this thing will be limited to 150mA for a USB 3 host or whatever current your traditional USB power source can supply (as those power sources really just do power supply of whatever amperage they support over a cable which happen to have USB connectors, rather than including a genuine implementation of an USB host with current limiting depending on negotiation with the USB device, so such power sources don’t require the device to do any USB negotiation to increase the current limit above 150mA).

    This is really “yet another run of the mill USB power breadboard adaptor” only the USB plug is USB-C rather than mini-USB or micro-USB (so, a different plug plus a handfull of minor components as per the standard of the circuitry to properly support it), so pretty much the same as the cheap chinese ones you can get from Aliexpress, though this one uses a Buck Converter rather than the $0.1 Voltage Regulator in most of the chinese boards, and actually does proper filtering of power supply noise and proper protection against over current, so it is a quality design for such things, though it’s not really a major advancement.

    Without the USB PD stuff I wouldn’t really say that it brings USB-C Power to the breadboard (in the sense of, as many would expect, being able to draw a proper amount of power from a modern USB 3.0 power brick that supports USB-C), more something with a USB-C connector that brings power to the motherboard, as that connector is really the total sum of what it supports from the modern USB spec.

    What would really be nice would be something that does talk USB-PD to the upstream host AND can convert down from the 20V at which it supplies peak power, so that you can take advantage of the juicy, juicy (oh so juicy!) capability of USB-PD to supply power (up to 100W right now, which will be up to 250W with USB 4), though if you’re pulling 100W (which at 5V means 20A, which is a stupidly high current that will melt most components in a typical digital circuit) from you breadboard power adaptor, then I’m pretty sure magic smoke is being released from at least one of the components on that breadboard and, by the way, you’re probably damaging the power rail of that breadboard (aah, the sweet smell of burnt plastic when you turn the power on for your half-arsed experimental circuit!!!)



  • Well, it’s their community, ain’t it?!

    If you go into somebody’s club, no matter how insane you think it is - say, a Flat Earthers Association, Pizza Is Best With Pineapple Club or some Church or other - and start hanging post-its all over the place criticizing their mad as shit beliefs, they’re absolutely entitled to tear them down and kick you out and they’ll even have the Moral High Ground doing it since your “right” to loudly be a whiny insulting bitch about somebody else’s beliefs doesn’t trumpt their right not to have loud whiny bitches insulting them in their space.

    Now, if they went after you for your opinions outside of their space, then that’s a whole different mater and you would be in the right, but that’s not what you’re complaining about: you’re going into a forum called Late Stage Capitalism to indulge in some “tankie-baiting” and then turn around and whine to the rest of Lemmy about how moderators are such nasty people and shouldn’t be allowed to take down your tankie-baiting posts in an anticapitalist forum.

    The simplest solution to this specific “problem” is for you to stop going into their space and act like a cunt there because you don’t like them. You can even block that forum if it makes you feel bad seeing a post from there in All.

    Sorry mate but you just sound like a total wanker trying to find support from the crowd to get away with being a total wanker whenever and wherever you see fit.


  • 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.




  • Whilst that is indeed true for the population in general, politicians are a bunch of people self-selected on being the kind who wants power.

    That kind of personality is generally less trustworthy (and more on the sociopath side of the spectrum) than the general population.

    There’s actually a study published ages ago in the Harvard Business review about corporate CEOs (so, not politicians but in many ways similar) which found that the ones who got the job not because they sought it but because of other reasons (for example, the CEO died and they were the next in line) actually performed better (as measured by the performance of the companies they led compared to the rest of their industry) than CEOs who had sought that position and, even more interestingly, the most self-celebrating showoff CEOs were the worst performing of all (from my own participation with politics I would say those would be the closest in personality to top politicians).

    Further, there are various pretty old sayings (back from the time of the Ancient Greeks and the Romans) about the best person to get a leadership position being the one who doesn’t want a leadership position.

    So I would say that most politicians in parties with higher chances of getting power (so, in most countries, the two largest parties) are crooked (not specifically corruption - such as getting money to pass certain laws of using certain companies for government contracts - but more generally using power, privileged information, influence and connections to benefit themselves even to the detriment of those who voted for them: a good example of crookedness but not corruption is how some US Congressmen use insider information they get in some Congressional Committees to profit in stock market trading).



  • 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.


  • It’s “mieren neuken”.

    A dutch person responding to my post already mentioned it.

    Also, as somebody who has moved there first and then learned Dutch whilst living there, I do recommend just learning it over there since it’s a much faster way to learn a language when you’re there surrounded by native speakers, with lots of things written in Dutch around you and with Dutch TV and Radio whilst actually using it, than it is as just learning from the outside with little in the way of useful practice with the actual experts of the actual language.

    Also you can easily get away with using English in The Netherlands whilst you’re learning Dutch - in fact if you have a recognizable accent from an English-speaking country it’s actually hard to get the Dutch to speak Dutch to you in the early and mid stage of learning their language since they tend to switch to English as most Dutch speak that very well.


  • That word isn’t originally from Portuguese from Portugal (though it is recognized thanks to the prevalence of Brazilian soap operas in Portugal) so it carries no broader “social” meaning and isn’t even commonly used there, so people wouldn’t care if you used it in Portugal as it just sounds odd there.

    If I understand the broader meaning subtleties of how it’s used in Brazilian Portuguese correctly, using “garota” for a woman is a bit like using “chick” for a woman in British English, which whilst not an outright insult carries a bit of a demeaning vibe (not as bad as the used of “bitch” - as in “my bitch” - in American English, but the same kind of treating women as inferior).

    This is probably because the original meaning of the word when not used for an adult woman (again, only in Brazilian Portuguese since it didn’t exist in Portuguese from Portugal) is “young girl”.





  • I’ve lived in a couple of European countries and speak 7 different European languages (though my German is kinda crap and my Italian not much better) and regularly take the piss by playing the “ignorant foreigner” with the expressions in other people’s languages and acting as if, by translating them literally, I totally misunderstood them.

    This works great because there are so many expressions in pretty much all languages which are have entirelly different meanings when interpreted literally but the natives don’t really think about it like that because they just learned that stuff as a whole block of meaning rather than having reached it by climb the language-learning ladder from “understanding the words first” as foreigners do.

    For example the English expression “I want to pick your brains” which has quite a different and more gruesome meaning if read literally or one the dutch expressions for “you’re wasting time in small details” which translates quite literally to “you’re fucking ants” and is my all time favorite in all languages I speak well enough to know lots of expressions in.
