The most interesting section - How It Works - could really elaborate on details a bit more.

Show some rigor.

> 25 deaths per million people per day

That's not the same age range as actively practicing researchers.

What was the goal then? Of those who demanded the change.

You are over-exaggerating.

As much of a snob that Jobs was it's nonsensical to say that he would've knowingly insisted on changes that locked users out from their devices. That's just nonsense. At the very least there would've been a prompt to change the password phrase or some such in upgrade. And if it did happen as an oversight, it would've been patched on the first report and some heads would've rolled.

He would've not let the abysmal slop like iOS 26 UI to ship ever.

Some things he didn't appear to care much about, the polished UX was his schtick.

This is more of urban legend that may somewhat hold true in tourist-heavy areas.

Just like it was with that amateur sub that imploded. It later surfaced the Navy heard the implosion and knew what it was.

You could also 4x the resolution by using half- and quarter-block characters from the top half of the ASCII table (or it'd be the PETSCII one i C64 case).

> It’s the same assumption is required for any hole punching handshake (including STUN).

This is incorrect.

Hole punching requires being able to predict external port. That's it. If the port remains the same, it certainly simplifies things, but ports going up (or down) by 1 (or 2, or 5) with each new mapping is quite common, trivial to detect and to punch through.

Claimed elegance is based on a very bold assumption that the NAT device preserves the source port of outbound connection.

Hardly the case in even half of typical deployment cases.

Unlike improper parking, running red lights should impact said privilege as potential consequences are way more serious.

But they didn't say anything about refunding them and you can bet Trump will oppose that and ask the SCOTUS to decide on it. They of course have an option to take their time to render the decision and then just dismiss the case without a comment.

That's what the GP likely meant.

The circus must go on.
