AT&T does have a plan where any provider can sign up to pay for their customers' data use, which is different from waiving costs for certain large, established sites.

Wait, how is that different?

I always thought Russell's paradox was basically just a formulation of the Liar's paradox in the language of set theory at the time, and that this was no secret. Its significance was not that it shed light on fundamental questions of philosophy, but rather that it poked a hole in what was supposed to be a foundation to all of mathematics.

Is there a formal theorem making this precise?

Fair enough. The horrifying part to me was not the moment the shots were fired, but the escalation and screaming of inconsistent instructions by an unmistakably bloodthirsty officer to a man who was clearly scared out of his mind and literally begging for his life.

That video is sickening. That man was murdered.

Alternatively, do the same thing with Twitch.

I watched some random streamer with 3 viewers play Skyrim an hour or so a day for several days, asking him what he liked/disliked about it, before purchasing it.

I feel like this is a very recent change; I've definitely created "burner" gmail accounts in the past and I don't remember providing my cell phone number.

Good point, though I'm not convinced Hilbert really avoids this. For example, look at n=3 here:

This might lead to say

. . . . . . . .

1 . . . . . . 2

4 . . . . . . 3

. . . . . . . .

when

. . . . . . . .

1 . . . . . . 4

2 . . . . . . 3

. . . . . . . .

is more efficient.

Generally speaking, it seems this is basically TSP.

Yeah sorry I meant like snaking back and forth, which you're right is not the same as pure lexicographic.

Yeah, sorry I meant like lexicographic on x, then swapping between lexi and reverse-lexi on y. Basically snaking back and forth.

Why is the Hilbert Curve any better in this situation than say lexicographical order on (x,y)?

Is there an extension that can display tab history as an actual tree?

Perhaps for now, but the ubiquity of smartphones could also bring them back in new and interesting ways. The most recent runaway hit was Pokemon Go, and though it was clearly a fad, it may have had more staying power if the social aspects were stronger, e.g. direct PvP battling.

Caveat: Take what I say with a grain of salt; I've never built a game in my life.

This might be naive, but I wonder if the essential part of mouse data could be compressed if only we understood it better.

Yeah I was thinking each appointment had a start time and end time.

Sounds like an effective filter to me. Where I work, this would be the first part of one of the interviews, with the second part being something more like "Given a list of calendar appointments, what is the maximum number which can be attended without conflicts?"

The blog post claims ~5% per hour.

Physical stores are being replaced by digital stores, which are better equipped to measure precisely how effective an ad is.

FWIW, I always thought giving the concept of "magma" its own word was a bit silly.

The natural numbers {0, 1, 2, ...} under addition are an example of a monoid which is not a group. Another example is natural numbers under multiplication.

An example which may speak to a programmer more: the set of functions which take a 32-bit int as argument and return a 32-bit int, where the operation is composition of functions. The identity is the identity function. Since not all functions are invertible, this monoid is not a group.

I would argue the concepts of monoid objects and the category of endofunctors on an object are simpler than that of monads, so this description does help. I come from a math background and had never seen this quote before, and I think it has given me a definition of (mathematical) monads that I can remember.

Haskell, unfortunately, is still quite opaque to me.

There isn't much competition among ISP's in large cities, either.

The post is nearly 10 years old, not sure if you count that as modern.

Tenured at Princeton, had already solved some fairly big problems in the field, and it helped that FLT had recently been "reduced" to proving a conjecture about elliptic curves which were already very much in Wiles's wheelhouse.

Not to take away from his achievement, but I think it is not stressed enough how much the proof depends on work from previous decades that a priori had nothing to do with Fermat.

FWIW, one does not accrue debt doing a PhD in something like Machine Learning.

That being said, I probably hit StackOverflow at least once a month for my job, and if I'm working on a personal side project it's probably more like once an hour.

I always figured this was because when it's cold out, people simply go outside less.
