Yes, an IoT device would certainly be a huge headache if it was on a proprietary protocol, I’d avoid that if at all possible. Thankfully, they haven’t made something absolutely indispensable yet.

Where I live, cashless payments via NFC. But I have the option of using a plastic card too.

It’s really just banking, I can still use the browser for most other things.

Hopefully Servo gets a good UI soon.

I’ve found it remarkably difficult to replace a battery in a modern smartphone, even as someone who’s quite handy with electronics. Any improvement is greatly welcome, and I wish we’d do more to make it easier.

It’s about usage patterns. If you know you only need 60% of the battery, charging it to 100% will degrade it more, for little utility. The newer Google phones get 7 years of updates, but without due care the battery will reach 80% of its capacity before that. On an aside, a battery is considered to have reached its end of life at a capacity reduction of 20%, and not 40%.

If you 100-0 the battery every day, then there’s not much you can do. But if you’re a lighter user, then using the 20-80% (or 40-60) part instead of the 40-100% part of the battery makes it last longer. And that’s good in terms of environmental sustainability, reduction of e-waste, and you can use the phone for longer, too.

Pragmatically speaking, for battery health you should charge only as much as you need the battery, so it sounds to me that in your case that’s 90%. Also, here’s a paper about battery charging:

Do you mean to say that this achievement had something to do with AI?

Fermat PRP testing with proofs instead of Lucas-Lehmer testing with full double checks

Looks like pure mathematics to me.
