    Blockchain. It was an interesting poc, but it has yet to have a useful implementation apart from scams.

          I worked in a company where this was used for implementing tamper evident logs, that allowed auditors to check for tampering.

          Blockchain is just a tool that can have legitimate uses other than scamming people.

      I’d extend that to conservatism in general.

      If there was ever strong evidence of humans generally being just as fucking stupid as the rest of the animals on this planet… It’s conservatism (the political ideology, not the act of conservation).

    The oldest two mechanisms of authenticating on credit cards.

    From oldest to newest, they are:

    1. Printed data on card.

    2. Magstrip (which basically has the same data in machine-readable form).

    3. Smartcard chip with contacts.

    4. Wireless.

    The first two mechanisms hand over all the data required to impersonate the cardholder whenever used, which isn’t very secure. Yes, there’s value to keeping a mechanism around for a while to permit transition time, but we should have had tap-to-pay hardware on PCs and phones and the like a long time ago.

      I disagree that we should have a card reader on our computers for payments.

      That is just a way too big of a security concern.

      I prefer something like the Swedish system Swish, you have a separate app on your phone where you can send money to friends and family as well as pay for stuff online.

      Sadly, while Klarna supports Swish, they require the use of a Klarna account to use it, and since most internet shops in Sweden uses Klarna it limits the ability to use it as I want to.

        and with that you need a smartphone, with a google-approved operating system and with it half of the factory bloatware, or otherwise you are barred from paying online, right? that sounds such a good idea.

        no.

          I said nothing about the OS on the phone, why would you assume that I like Android?

          I am an iPhone user, but that is beside the point, if Swish and BankID could run on an open mobile plattform, I’d be happy with that.

          My point it to separate the main computer from the payment system while still being convenient.

          I am a bit confused as how you missed that…

            I said nothing about the OS on the phone, why would you assume that I like Android?

            that’s not what I assumed. I assume that this app would only support the 2 most popular mobile platforms, and that on android, as is tradition with payment related apps, it would refuse to work when it detects that your phone’s software has been changed in any significant way.

            if Swish and BankID could run on an open mobile plattform, I’d be happy with that.

            current trend is to make these apps OWASP compliant, which dictates that all apps should at least be an undecipherable, obfuscated black box, and better even make use of the OS’s integrity checking system, like play integrity on android.

            My point it to separate the main computer from the payment system while still being convenient.

            I am a bit confused as how you missed that…

            I did not miss that. I was commenting on this, why it would be harmful in today’s world.

      Racism will never die as we evolved to be tribal. Best we can do as a society is make it unacceptable. Which was happening when I grew up in 70s/80s America. Now we’ve backtracked and gone all-in with dog whistles.

      Young earth creationism

      What I hate so much about that, is all the “evidence” just points to some near extinction level event that humans worldwide suffered.

      And obviously for that to have happened, it means there had to be a lot more people.

      Like, entire cities/tribes/whatever were wiped out everywhere, but some had individuals survive. Which explains how “the last two people” could have kids who just happen to later have spouses and kids of their own without any explanation for where the new people came from.

      They were just outside of walking distance.

      Over the 300,000 plus years anatomically modern humans have been on Earth, that’s probably happened a bunch. Hell, we’ve had 2-3 actual ice ages over that span.

      We don’t know shit about 250k of those years.

        From what I understand (and as a Christian), it’s those Christians that take a literal reading of the Bible, not understanding that those parts of the Bible aren’t meant to be read literally but are about the WHY of creation rather than the HOW. It’s about WHO God is rather than how He did things.

          Either that or Genesis is just an explanation made up by a people group that had little to no idea how anything in the natural world works lol

            If you squint real hard, Genesis is a tale of stellar and planetary formation. Then comes evolution. Give the first bits a read! Yeah, evolution is mixed up a little, still surprisingly on point for a bunch of Bronze Age sheep herders.

            Then there’s a second tale, in the same short book. What a clusterfuck. But I can still see some real history in it. If I squint real hard.

              Yeah seeing as the writers of the Pentateuch didn’t even know what the stars were, I’m pretty sure that’s all a coincidence lol.

      What’s weird is the young Earth thing is relatively new. Before the 1850s or so, you would be laughed out of the room. As ignorant as we were, naturalists were having a hard time trying to figure a world that was millions, or 10s of millions, of years old. Churches, of any stripe, sure as hell wasn’t preaching it.

      And here we are, with the flat Earth idea being even newer.

    I thought phone numbers and traditional telephone service would be dead by now. Instead, purely internet-based communication services often use them as an identifier.

      telephony only uses a subset of internet things so building just telephone lines is cheaper, which matters especially in the global south

        I’m no expert on the subject, but it’s my understanding that mobile networks are being deployed much more widely in the global south than wired telephone lines, and they’re usually internet-capable.

          wait, you’re right. not sure what i was thinking of… then i guess it’s an easy way to get a unique human-readable subscriber identifier?
