It's still here, it's still killing and disabling people, but due to vaccines and antivirals it's less prevalent than it was.</p>

<p>Really? Where I live a patient is always able to refuse any medical procedure or treatment, unless they’re unconscious or otherwise mentally unable and the procedure is considered necessary to save their life. They certainly can opt for a non-ambulance transfer, though here it would be free even though a regular ambulance service typically isn’t.<p>Consent for treatment is a core principle of medical practice.</p>

<p>I have a Polestar 2, 2022 model even so it's not fresh off the lot.<p>CarPlay navigation shows on the instrument cluster. The speed, state of charge, etc all move to the side so the map is right in the middle for quick viewing. Then the infotainment screen can show music or the tiled music/navigation view that CarPlay supports.<p>Basic music controls are on the steering wheel of course, readily accessible.<p>The lack of multitouch is slightly annoying, but it's not something I ever use. If I ever can't see what I need on the navigation I simply look outside for the road signs, which still exist.</p>

<p>A lack of wear components.<p>A permanent magnet motor uses permanent magnets on the rotor, but an electrically excited synchronous motor has an electromagnet on the rotor. This requires a rotating electrical contact which has normally been made with slip rings and carbon brushes. These wear over time and need replacement.<p>Most large electric generators are externally excited synchronous generators using carbon slip rings, so it's a well understood field.<p>This can be made contactless using inductive coupling and a rectifier - since inductive coupling needs AC but the excitation coil needs DC - at the expense of some efficiency.<p>You can see the efficiency difference - Renault claim 92% efficiency but permanent magnet motor EVs have touted efficiency over 95% in the motor.</p>

<p>When it was developed it was assumed that the cost of cellular equipment and, in some countries, the regulatory hurdles required to get authorisation to purchase radio transmitters that operate on licensed bands would make it almost impossible to do this.<p>I worked in a company that had a base station emulator in their testing lab in 2008. I can’t recall the cost but it was well over $10,000 and only worked with direct antenna coupling, it couldn’t broadcast.<p>Now we have software defined radios.</p>

<p>That’s not how it works. Not on iOS anyway.<p>For a standard notification the content of that notification is sent through the push notification servers. This includes the title, text, icon, grouping, and sound presets to use. The majority of user-visible notifications are sent this way - the app on the device does not run.<p>That allows the OS to display your notification without ever running the app, which saves limited resources on the phone. Originally this was the only option, a push notification couldn’t start your app.<p>These days an app can also register a notification extension which is a standalone program that can modify the incoming notification. It has 30 seconds to do whatever it needs to, though you need to be careful with RAM use or the OS will kill the process and present the notification unaltered. Generally you’d put something generic in the push as a fallback.<p>There’s also background notifications. These let the app run for 30 seconds and the app can post a local notification during this time, but they’re not guaranteed to be delivered. The OS can decide the system doesn’t have the resources and defer or drop them, or terminate the app before it’s finished if the ram is needed elsewhere.<p>There are some other special cases depending on what your app does.</p>

<p>> but it does absolutely nothing with actual pain<p>Neither paracetamol nor ibuprofen work by blocking pain. Depending on the type of pain and your physiology it can range from really effective to not at all.<p>I only take paracetamol, it works better than both ibuprofen and opioids for me. I know other people who have the exact opposite experience. There’s no absolute here.</p>

<p>They can’t, it’s caused by the capacitors required to suppress electromagnetic interference caused by the switch-mode power supply. These allow a very very tiny amount of current to leak through from the mains side, which is then capacitively coupled to the metal case (IIRC Apple do not connect the case to power negative) reducing it further, but it’s enough for humans to sense it.<p>It can be avoided by using a grounded power supply, but because there are large countries that have ungrounded outlets in common use the most designs are ungrounded.</p>

<p>Interesting, those are problems I don't have, I guess due to my work and workflow.<p>Command-` works for window switching as I expect, probably simply due to being used to it so I know exactly how It works.<p>Window positioning is an interesting one. I can't stand windows being positioned through tools, I stack them like you would with papers and shuffle through so the edge overlap is really important.
