  • In almost all microwaves, the control circuitry or mechanical switches only ever switch 2-3 power circuits: motor+fan(+bulb sometimes separately) and the heating (transformer+diode+capacitor+magnetron) high voltage circuit. It can therefore only switch the heat between 0 and max, usually in a slow (15-30s period) PWM cycle (that hopefully does not coincide with the tray rotation period). The inputs can be manual only, or sometimes there is also a scale, moisture sensor and microphone, along with thermal fuses for safety.

    I think the pizza setting is just generic medium one with short 50% cycles to allow the heat to spread. The popcorn setting can be much more interesting:

  • That’s exactly what Microsoft did in the 1990s after an antitrust lawsuit for hindering free browser selection: integrated Internet Explorer into Explorer to have an excuse for having it preinstalled.

    The EU is taking similar steps but I tgink Edge WebView will stay essential. Removing it on a laptop broke biometrics (aka Windows Hello: fingerprint sensor and face recognition) and I had to use a restore point. Seems sketchy to use a browser engine for essential security features – at this point, I would hope I had triggered some OS tamper-detection because the alternative is an OS whose login system is infected with an unpopular browser not because it enhances security but out of spite, and I don’t think exploiting legal loopholes leads to most secure solutions.
