I use the "face unlock" on Android, too; but it falls back to {another method}, which is a pattern in my case. It also auto-unlocks on Bluetoothing to the car.

I've also noticed that it always requires the pattern after powering up or after a long time (e.g. overnight).

The paper does take account of this: regenerative braking is assumed for EVs and (conservatively) zero brake-wear is assumed.

Having RTFP, they do take regenerative braking into account - EV cars are assumed to use regen and have effectively zero brake-wear.

One of Feynman's memoirs includes the haha-only-serious observation that mathematical theorems are either unproven or trivial, and this is simply a re-statement of the same principle.

And actually, there's a lot of speculation about whether colonies exhibit intelligence or consciousness (eg Hofstadter's Aunt Hillary, but also Jack Cohen & Ian Stewart's Heaven - they also did the Science of the Discworld series with pterry).

The rules are that, for the next five years, any .co.uk owner can register the corresponding .uk domain. If there isn't a .co.uk, the .org.uk owner can register, and if there isn't a .org.uk owner, the .me.uk owner can register it.

All other .uk subdomains don't get a bite at the cherry. Nor is there any protected time where a .org.uk or a .me.uk owner can register the .uk domain if the .co.uk owner doesn't want it.

a century ago, the same sorts of complaints were being made:
see The Ragged Trousered Philanthropists by Robert Tressell.

Face recognition (at least the Android Jelly Bean/Kit-Kat version) gives too many false positives at the moment. Somewhere between 5% and 20% of the time, my face does not unlock my phone/tablet, and I need to enter a PIN.

Also, the scope for involuntary unlocking is much larger.

If you want to know if I've read an email:
request a return receipt
If I want to give you that information, I will.

Goodness, there's an existing, non-scummy way of working all this out which preserves user expectations of privacy and provides you with the information you actually want, not a poor proxy of it.

Also, knowing about QS implementations lets you know when it's been done wrong.

Case in point: Microsoft's C runtime library shipped around the time of Windows NT and Visual Studio 6 had a sub-optimal qsort implementation - it took 97 seconds (on a 600MHz Athlon) to sort 260,000 integers with a constrained set of values (0-180), whereas other implementations (eg Numerical Recipes) could do it three orders of magnitude quicker.
Delving in, the qsort() algorithm didn't exchange elements where the value equalled the partitioning element, which leads to increased comparison function calls (effectively proportional to 1/range).

Most phones, even if you remove the SIM, will allow you to phone the emergency services (999, 911, 112 or whatever). I believe it's a requirement of the GSM standard.

Is this real? (Metallurgia International's web site appears to be gone, so there's no direct proof).

Surely even the worst kind of journal would ask that the Error! Reference source not found broken cross-references be fixed?

Well, Intelligent she might be (gives you the afternoon off, after all), but it's a bit more dispassionate than I'd want my Benevolent Omniscient Being to be. Have you read about all those parasites? The ones that eat their host from the inside out, the ones that affect the brain, so the host goes wandering out into wide open places and gets eaten, etc.

It's almost Lovecraftian.

You could, but we have so many more colours nowadays.

That happens all the time, I've seen the videos.

Oh. "striping", not "stripping". As you were.
