    I never needed more because I just had a dock. My monitor, keyboard, mouse, and Ethernet cable stayed in the same place, so I’d just bring my laptop home and plug in a thunderbolt dock, and I’d have every peripheral I needed. And I’m someone who tries to use wired stuff over wireless whenever convenient.



  • definitely not for sensitive work.

    I would argue that desktop software capable of doing this (storing and using past pixel values to calculate some sort of output) violates the principle of least privilege, so that an OS that supports this kind of screensaver being possible shouldn’t be used for sensitive data, even if that particular screensaver is disabled.

    Better to harden the OS so that programs (including screensavers) can’t access and store the continuous screen output.

    That’s one of the problems we have with Windows Recall. We don’t even want the OS to have the capability, because we don’t want that data being copied and processed somewhere on the machine.





  • Visa/Mastercard requires all cardholders, cardholders’ banks, merchants, and merchants’ processors to follow the comprehensive set of rules for disputed transactions. That way the dispute process tends to be uniform across different banks and across different merchant/payment processors.

    The network sets the rules, while the banks implement those rules on behalf of the cardholder and the processor implements those rules on behalf of the merchant.

    So replacing the network will require a comprehensive replacement for the network’s dispute resolution rules (assigning who is responsible for paying when certain things happens) and procedures (how a cardholder can initiate a dispute and how that gets resolved).



  • Fahrenheit today is literally defined through Celsius

    The same as pretty much every unit they use

    At this point, that’s basically every unit other than the seven fundamental units. Degrees Celsius is defined from the fundamental unit Kelvin.

    Plus the actual definitions of those fundamental units were defined based on historical measurements tied to former definitions. Today the second is defined around the frequency of the cesium-133 atom, but it was traditionally measured as 1/(60 x 60 x 24) of the time of a single rotation of the earth, which stopped serving us when we realized the rotations had too much variation between days. The meter is currently defined around the speed of light and the second, but was previously defined in terms of what they thought the Earth’s circumference was, and then a metal bar they kept in Paris, then based on the wavelength of light emitted from a transition in krypton-86. Same with the kilogram, currently kept at Planck’s constant but previously based on a particular chunk of metal that was mysteriously losing mass over time, and before that defined from the density of 4°C water and the definition of the meter.

    Conventions are important. The history of how we got to particular conventions can often be messy.

    You can turn off higher level location services at the OS level, but at the radio level the cellular network will always need a precise enough location to handle tower handoffs and timing issues between the tower and phone, as well as modern beam forming techniques where the tower “aims” the signal at the phone. The simple act of the phone communicating with a specific tower tells the phone where it is (sometimes with surprisingly high precision).

    911/emergency services also use more low level location techniques, but I’m pretty sure those functions don’t get called unless you dial an emergency number.





  • The Fediverse is designed specifically to publish its data for others to use in an open manner.

    Sure, and if the AI companies want to configure their crawlers to actually use APIs and ActivityPub to efficiently scrape that data, great. Problem is that there’s been crawlers that have done things very inefficiently (whether by malice, ignorance, or misconfiguration) and scrape the HTML of sites repeatedly, driving up some hosting costs and effectively DOSing some of the sites.

    If you put Honeypot URLs in the mix and keep out polite bots with robots.txt and keep out humans by hiding those links, you can serve poisoned responses only to the URLs that nobody should be visiting and not worry too much about collateral damage to legitimate visitors.
