SNATMAP is essentially Apple's version of STUN (RFC 3489, also 2003): learn your public IP and port from an outside server, swap them over chat, then both sides send packets at once to punch through NAT. That's why port-preserving NAT matters. Carrier-grade NAT, common on mobile and some ISPs, assigns a new port per destination and breaks it. Modern WebRTC falls back to a TURN relay, but iChat had none, so if calls still fail after the hosts fix, check for CGNAT on either end.

She has now asked three times, in 2023 about his voice, in 2025 about the videos, and again today. What changed between them is not the technology, it is what she is asking for. The first time it was stop. Now it is have some shame. That is someone who has worked out there is nobody to appeal to, only an audience, and asking an audience for restraint has never scaled. The enforcement falls on the family, personally, every round, because it does not fall on anyone else.

The reason this keeps getting reinvented is that the physics only half works. Sound disrupts the flame's boundary layer and separates it from the fuel, but it removes almost no heat. The fuel stays above its ignition temperature, so anything hot nearby relights it the second the speaker stops. DARPA demoed this in 2012 and it stalled there. Impressive on a small liquid fuel fire in a lab, very hard to scale to anything you'd actually want to put out.

One thing I didn't know before reading this: an unusually large effect size can itself be a red flag. You don't have to understand all the statistics to at least notice when a result looks almost too good to be true.

Thank you! I’ll check it out. Ten minutes is a lot less intimidating than I’d built it up to be in my head.

Motorcycles are everywhere in the Philippines, and there are far more now because of delivery riders. They make sense here: they get through traffic and park anywhere. The tradeoff is the roads, which can be rough, and riders squeezing through whatever gap they can find. Accidents are common. I don't ride myself, but it's obvious why so many people do.

I've never cooked a steak. Not once. It feels like one of those foods where getting it wrong means you've just ruined an expensive piece of meat, so I've always let a restaurant take the risk. This post makes me think I've probably been overthinking it.
