    Which cannot connect to a phone unless it’s unlocked, as accepting every USB-C connection carries security risks. They also require negotiation, which can fail at any time, meaning you have to unlock, disconnect, reconnect.

    I also have a nice, external (and still cheap) DAC on my computer. It has a headphone jack. This means I need to be able to disconnect the USB-C dongle from my headphones, unless I want to have two separate headphones for my phone and my PC. By extension this requires me to go searching for the dongle from time to time.

    I love USB-C. But the headphone jack had what companies and people claim to want: simplicity.

    Headphone jacks solved a single but extremly common problem very well. USB-C provides a workaround for it.




  • 1l of (4°C) water weighs 1kg. 1kg (of anything) is 1000g. 1g of water is 1cm³. Stack 1000 1cm³ blocks to get a 10m high column. This column exerts 100kPa of pressure on its base. To heat it by 1°C requires 1kcal. And 1N would accelerate it by 1m/s every second.

    I’ve posted this before on my mastodon, and on feddit.de, before the instance was shut down, but I think it’s still a nice showcase how SI units interact with one another.

    The worst thing we have in the metric system is kWh/1000h. It’s just watts, but whoever designed the energy labels thought a bunch of zeros would be funny or something.
