  • “But personalised ads are really convenient!”

    Not seeing ads is really convenient, and I have trouble understanding why anyone wouldn’t block ads aggressively on every device they spend much time using in 2025.

    To cover a couple common objections:

    It’s a corporate/institutional device and I can’t

    Then it’s the institution’s IT department I’m puzzled by. If I was running corporate IT, ad blocking would be part of the standard install. The FBI recommends it for security.

    The device is too locked down for that

    Why would you buy such a device, or continue using it now that you know better?


  • Someone logging timestamps for messages received on both ends of a conversation would be able to determine that two people are probably talking to each other given enough data. Signal is probably not doing that, but Signal’s other security guarantees provided by an open source client that encrypts communications end to end hold even if the organization was infiltrated or taken over by a bad actor. The anonymity of participants in a conversation is not protected as strongly as the contents of messages.



  • It is like paying to unlock satellite TV reception (even though we are receiving the signals the whole time).

    It’s reasonable to charge for this because the value is in copyrighted content and a service that costs the provider money to operate. The same would apply for satellite radio in a car or an internet-based streaming service. It is not reasonable to charge for access to the adaptive suspension or seat warmers that are already in a car a customer bought. That breaks the traditional model of ownership.

    An interesting middle ground might be to allow the owner to install arbitrary software on the car, and charge for the OEM adaptive suspension app. I think I would like a world where things work like that; OEMs would whine about security to no end.

    I think it should be legal to attempt to decrypt satellite signals without paying; if the satellite service is designed well, it won’t be possible. All the anticircumvention laws should be repealed.


  • It’s an electronic parking brake. Those are common now because a small switch takes up less interior space than a lever for a cable-actuated parking brake, and the computer can disengage the parking brake if it detects that the driver is attempting to drive with it activated. The computer is involved in brake pad replacement to tell the parking brake motor to open to its widest position to accept new pads, and calibrate itself to their thickness.

    This requires a special adapter and software subscription rather than a button on the infotainment screen because Hyundai is engaging in rent-seeking and perhaps trying to direct business to its dealers.







  • I’ll expand this question to my entire social circle.

    I haven’t found that anybody cares about my email provider. It doesn’t affect them because email is federated. Nobody has ever asked me why I’m mailing them from a domain I own rather than a service provider they’ve heard of.

    Where I do run into a lot of resistance is trying to get people to use Signal. Some people seem to find the concept of having multiple messaging apps objectionable, which has never made any sense to me as long as they have basic computer skills. On occasion, I’m on the other side of that conversation when I’m unwilling to use Facebook Messenger for reasons that should be obvious to anyone in this community.





  • The amount of time the battery spends at higher voltage definitely affects its capacity over time. There’s plenty of research on Li-ion battery service life characteristics done with greater scientific rigor than is possible with batteries installed in phones.

    It can take longer than the few months these tests required to see the effect. A phone that’s usually stored at 60% will eventually show a big capacity advantage over one that’s stored at 100%. That’s probably mostly true at 80% as well.

    For some anecdata, my Pixel 4a has spent most of the past five years limited to 60%. It reports 1152 cycles and 91% capacity.
