That is one reason they don't do that. (Another is that the net would be useless if you upgraded the cameras...) Whatever the sensing technology, everyone uses it to build a "state of the world" model which is then fed into a

Better a rejection than complete radio silence, though. I went through a job hunt a couple of months ago. CV screening was by far the most stringent part of the process for me. I passed all of my phone screens and got offers from most of my

It also coincides with them raising a crapload of money (hundreds of millions iirc) at a significantly higher valuation than they had a couple of years ago.

They're not aiming for 16%. They're not changing any of the numbers involved, they're just changing the order of two dice rolls. It's a creative little rejig they probably hadn't thought to do before (or perhaps

They make changes to address each of the issues as they crop up, so the question they need to ask is whether the EU will keep finding reasons to hand out record fines. I guess that boils down to the degree to which they attribute the fines

The regulatory bang-for-buck is pretty high, though -- no complex rule-making, no significant change in procedure, just a 16% bump for practically nothing.

More to the point, foreign carriers are literally not allowed to fly US domestic routes. Plenty of international competition would love to (and foreign governments might even subsidise those flights!) but trade protection keeps them out.

Studies show that the pay differential for "all but completed degree" and "completed degree" are stark. Researchers have said that this indicates that a large fraction of the "value" of college is just signalli

Isn't paging orthogonal to using brk? Or is "paging" something more specific than "virtual memory is handled by the OS in big chunks"? I guess your allocator can try its best to prevent fragmentation, but you'r

Fair, but I think this all amounts to "A linear patch of memory is fine primitive to build an allocator or standard library on." The "not faulting on address zero" thing is interesting but not crazy -- only broken progra

"Full rein". And the C heap is typically a linear memory region (that grows monotonically) isn't it?

I'm not in ML, but one thing I remember from school (a million years ago, before ML was big) is that Newton's method needs a matrix inversion every iteration, which is expensive when you have a lot of decision variables. Not sure

Sometimes. If your profile is "lumpy" enough that can be true, but often the performance problems of slow languages manifest as annoyingly flat death-by-a-thousand-cuts profiles. (Especially after the low hanging fruit has been pi

Mostly Ruby web app workloads aren't CPU-bound. And when they are, you're using a language that is 100 to 1000 times slower than C. That is, for a CPU-bound task, you might be able to replace your thousand node k8s cluster with on

Shouldn't anyone who passes through the training be considered qualified? If training is expensive then you no doubt want to prevent people from starting if you don't think they're likely to finish, but the metric there shoul

Right. The article calls these things "fallacies", but that only strictly means that they're not slam-dunk arguments. Logical fallacies aren't necessarily bad heuristics, they just don't necessarily assure strict lo

RLE is probably fine too. Easy to do set operations on RLE data structures without "decompressing" them too. Quite a bit simpler than BSP trees for most people I think :-).

Fixed point might usually put the "binary point" in between bits, but when doing a multiply between two of them you still have to do at least an integer multiply before the bit shift. Ditto division.

In informal contexts it's also used as a fudge/handwave, purely as a questionable analogy that nobody is expected to take too seriously. `theptip` almost certainly knows that O(1000)=O(1), they were just being playful.
