  • fizzle@quokk.autoAsklemmy@lemmy.mlWhy NFC on phones?

    The short answer is, NFC only provides a brief packet of data - the details you would see on a physical card then the vendor’s machine takes the money from the customers bank account. Payment with a QR code requires your phone to actually interact with your bank and transfer the money from your account.

    The reason why one is more common than another in different locations is historic.

    In western countries you’ve been able to pay by card at most retailers for several decades. Originally there was a magnetic strip on the card, then a chip on the card, then the card did NFC. That being the case phones could just emulate cards by doing NFC and you could pay for things with your phone. Vendors didn’t need to do or change anything.

    In South East Asia (and elsewhere?) that’s not really the case with many smaller street vendors requiring cash payment until recently. Many people might have cards but they were really only used for identifying yourself at the bank or cash machine. Even in larger cities, smaller food vendors often required cash payment - at least up until covid. That being the case there was never an era where people carried and used bank cards, so QR codes are the alternative tech.




  • I disagree.

    Its slightly firmer science than star trek, but it still makes a lot of license IMO.

    I dont think the cost of sending humans to Mars or to do asteroid mining will ever be justified. Bots, and not humanoid ones will explore the frontier of space, and collect the minerals we need.

    If you think about all the stuff humans need to survive for any length of time it just doesn’t make any sense to send a human.





  • Ay?

    Do you mean only the super rich will be able to travel?

    The only travel anyone will be doing in the next 100 years or more will be going to the moon to squeeze into a tiny smelly hab module to figure out how to avoid getting regolith in your ass crack.

    I think space travel will be the exclusive reserve of hard core science nuts.

    Even in say 500 years. Will there be a “colony” on Mars with anything more than a dozen science nerds? I doubt it.



  • Im not really sure what you mean by lying down? You’re not always lying down. Surely gravity is less relevant when you’re lying down anyway.

    … I dont have a good understanding of physics but sci-fi novels suggest a few problems on small ships.

    The first problem is the difference in gravity between your feet and your head. In a small command capsule like Artemis 2, your head might be near the centre at 0g while your feet are at the outside at 1g or even 2g. How hard does your heart need to pump blood? Would this create some kind of blood pressure problem?

    The next problem is how it would “feel”. Is it called the Coriolis effect?

    In a small ship you might experience 1g, but it would feel like you’re being spun around in a washing machine. Your ears would tell you that you’re constantly changing direction and it would 100% fuck you up. In sci-fi the spinning thing needs to be large enough that some g-force is produced without you feeling that sense of motion, or at least for ot to be small enough that you get used to it.

    Another problem I just made up is that if there’s no gravity then 100% of the inner surface area can be terminals and readouts and equipment. If you create gravity then you need a floor to walk on which will use a heap of surface area.



  • Originally I didn’t like blocking people or communities at all but I’ve realised the lemmy experience is dramatically improved by blocking idiots.

    The thing is lemmy is a relatively small community. If some nutter posts and comments every day they can really shape your impression of the place.

    Some users have very little life experience, and depth of understanding, and are just fixated on some single issue. I’m not here to argue with that type of user.

    Yesterday I blocked a community just because the single mod didn’t understand the problems caused by editorialising titles when posting articles.


  • For years it has been repeated again and again that gas is needed to firm renewables when “the sun doesn’t shine and the wind doesn’t blow”. Events have shown the opposite: renewables are needed to firm oil, gas and coal when the ship won’t go and the pipeline doesn’t flow.

    Indeed.

    Nothing new here though. Half of us have known we need to decarbonise industries as quickly as possible, while the conservatives have as usual been trying to avoid doing so.

    As I’ve said a bunch of times over the last few weeks, I’d like Albo and other leaders of like minded middle powers to stand together and condemn Trump’s behavior. It’s absurd that everyone is too scared to say anything. He’s caused global harm in order to further his own interests.


  • My son and daughter are citizens of the country they were born in, but could choose to acquire citizenship of their mother’s country of birth, by descent.

    For my daughter, this might be a nice-to-have as it would make things easier for her if she chose to reside there for any period of time.

    For my son, it’s a more complex choice as he would be required to complete military service in that country. For some teenage boys that might be the adventure of a life time, for others it would be a nightmare. I’m planning to let him decide what he wants to do.


  • I really, really dont want to defend this guy, but ill just point out that the conviction was molesting a child. Theres a spectrum of severity of sexual assault cases and not to diminish the suffering of the victim, the language and sentence in this case implies that the act was not particularly severe.

    As youve said yourself, the deterrent aspect of sentences does not deter other perpetrators.

    Weird punishments like physical (not chemical) castration are more about appeasing victims and the public like your good self, than they are about mitigating the impact of the crime and minimising harm now and in the future.


  • Tough one.

    Sentences in modern societies should focus on mitigating the impact to victims and rehabilitating the offender.

    Crimes that harm minors intentionally are a special category, and while I understand the hatred I think that wanting to punish the perpetrator for no other reason than revenge doesn’t really help anyone.

    The requirement that permanent residents have their visa’s cancelled when found guilty of a crime is really just to ensure that the migrants we accommodate are fit and proper, compatible with Australian values. In this case, we’ve accommodated this guy for the last 40 or 50 years, and to remove him for the last 2 or 3 years of his life when he’s vulnerable is just vengeful punishment because the law happens to allow it in this case.

    I mean, there’s plenty of Australian citizens convicted of similar crimes who are allowed to serve their time and then released to live out their days in Australia.

    I don’t think that returning him to the UK serves any purpose.


  • It was, a strange and unfulfilling experience.

    I smoked weed daily during that period.

    I was hiking in Thailand and these guys showed up with the pipe and stuff. I paid for a pipe, nothing. Paid for another, nothing. Paid for a third and still nothing.

    A friend i was with said he was feeling it. A floaty feeling. The guys with the pipe, and my friend, and me all decided that I shouldn’t keep going because it might all hit me really quick. We had to hike the next day so I didnt want to be all fucked up.

    Later I smoked a little weed and it felt different, more floaty.

    In summary I was expecting something more dramatic. I would describe it more like taking the regular dose of oxycontin - a bit tired but not “an experience”.
