I guarantee that UPS has had teams of computer scientists, mathematicians and probably statisticians working on package scheduling and routing over the decades. The traveling salesman problem, which UPS package routing is, is an NP-hard problem, which means that guaranteeing an optimal solution is going to take an exponential amount of time. There is no "established" way to exactly solve NP-hard problems with large inputs in a reasonable amount of time. Rather, there are approximate approaches which use domain-specific information to inform what kind of heuristics one can use to achieve a tolerable result.

I would write far out of the money puts on TSLA. Look at the options chain! If you were to sell 1 put on TSLA with a strike price of $1200 and maturity date of 7/24 you would collect $780! That means that if TSLA doesn't drop from 1600 to 1200 by Friday you get to keep that $780! Only issue is you need to put up ~120k in collateral
No. We can compute the number exactly without computing all primes below a trillion (that’s why this article can mention the exact answer). See https://en.wikipedia.org/wiki/Prime-counting_function#Algori...

For those working on a language that supports automatic differentiation: implement such an algorithm, and differentiate it to get a primality test. I think that would be a good test for your compiler.
Yes, I agree it's too much, but that comes from the editor, tree-sitter only provides the metadata (which is way more accurate than the regex-based approach).

Not at all, I recently completed a road trip from Chicago to Blue Ridge, Georgia with a full car (5 people, including me) in a Hyundai Sonata. It was an 11 hour drive. On the way there we stopped exactly once, and on the way back we stopped twice.

If we did this in a Tesla, we would've had to stop far more times, or each stop would have to have been much longer. That's not great.
Not sure why that's happening. Is it still like that for you? What browser/OS?
I've been a long-time user of a Google virtualization toolkit that was developed in the open. It is full of such design docs:

That concept is what has helped me get over the A15-20 hump. It's more important to draft cards that shore up immediate weaknesses than it is to draft cards that might pair well with other effects in your deck. Draft for the short-term, not the long term, because stronger short term victories means you can pathfind more aggressively and acquire more gold/rewards.

I'd say that's probably the most important "ah-ha" moment where my winrate really started to significantly improve. That and knowing when to min/max # of combats while pathfinding.
Eventually, but it doesn't necessarily need to happen right away.

It seemed wrong to me at first, too, but eventually I saw how it made sense. The aspects of the relationship that would normally be fraught with fear and uncertainty -- is this person invested in my happiness, will this person respect my confidences, will this person use what they know about me against me, will this person turn against me if they learn my shameful weaknesses -- are encoded in their professional obligations. That's not enough for it to be a great working relationship (you need some personal chemistry as well) but it's a great foundation to start from.

I think that would be fine if they also gave a mandate to deliver letters at a fixed price regardless of destination.

Disclaimer: I know very little about python internals.

There is a "true" main function for the interpreter itself. From the perspective of the operating system and CPU the python code isn't executing, the interpreter is.

But conceptually, the python code probably doesn't have main function. Python code is so far abstracted from how the CPU works that it likely doesn't need one.
Everyone investing on Tesla is counting on it becoming a kind a Facebook for Cars, using the power of its stock to kill and buy competitors.

Personally, I'm most interested in some rather esoteric applications: in a very real sense, our QPU can be thought of as "programmable matter". Specifically, it can be used to simulate various crystalline lattices [1, 2, 3]. Part of my job is figuring out how to best represent those lattices with our systems, so I'm clearly biased.

To directly answer your question, I'm most impressed by [3]: materials with a specific structure called the Shastry-Sutherland lattice exhibit a quantized response to an external magnetic field. This is a place where materials clearly demonstrate a quantum effect (itself a demonstration that quantum mechanics are necessary to describe the universe) -- and when we use our computer to simulate it, that effect is clearly visible.

I do think of physics experiments as real-world problems, but some of our customers are doing really neat stuff that's much closer to a lay-perspective of what "real-world" means. For example, Groovenauts and Mitsubishi Estate collaborated [4] to optimize the routing of waste-collection trucks. Another one, a collaboration [5] with Menten AI, involving protein design (admittedly, a bit over my head) made use of our hybrid sampling service and they're now doing wet-lab experiments. We've collected [6] quite a few of these applications, and I'm barely familiar with a few of them.

It happens when the oversight has been pared back over the years and finally outright ignored. It happens when an administration decides to exploit those vulnerabilities and "norms" (ie, loopholes because there isn't an actual law that holds a government officials accountable).

PSA is definitivly used for early screening prior to diagnosis [1].

But we might use the word baseline for different things.

As PSA is influenced by the patients physiology and activity [1], it can be helpful to understand what the non-cancer baseline/standard PSA value for a specific patient is, this would need to be established by multiple tests over a couple of years. This can help in distinguishing noise from signal later.

After surgery the PSA baseline is zero (by definition, the generating organ has been removed). Any value above zero indicates either metastasis in other body parts or a really bad surgeon.

After non-surgery primary treatment (radiation, ...) the PSA does not (necessarily) fall to zero, so here one takes the lowest value after treatment (with a grace period) as the baseline.

Crux was a pretty straightforward choice. Didn't really consider any non-datalog DBs. I've used Datomic quite a bit, but preferred crux since it's open source, has filesystem persistence and doesn't require a separate process for the transactor (nothing wrong with Datomic's choices; the tradeoffs just make it unsuitable for Biff). I went with crux over datahike since it's more mature and has postgres persistence (and Kafka persistence, not that I need that yet). I haven't actually used the bihemporality features of crux yet, but maybe they'll come in handy.

I was about where you were 40 hours in. Then I bought this game on switch so I can take it everywhere with me and have since dumped about 500 hours into the game. I only recently got all characters to A20. Still working on A20 heart kill and a few other achievements.

It's always intrigued me seeing other people pick up the game and master it much more quickly than I did. There's some people that get their A20 heart kill just 100 hours into the game.

I really enjoy the feeling of slowly but steadily gaining knowledge and intuition about the game - in the 500 hours of play there's been no shortage ah-ha moments throughout. Truly one of the best $/entertainment value games I've ever purchased.

As I said, you'd need some measure of concurrency. Or perhaps a non-blocking reader. Try to get new stuff, if it's not there continue on, I just don't like getting "null" responses like that as it's too close to a busy-loop which is, well, poor form. I generally write code that interacts with the world in its own thread/process/whatever so it doesn't block the rest of the system unless appropriate.

The utility here is if you can process each element one at a time. If you need everything to get a meaningful result it offers no benefit to you.

They probably know that visible effects of global warming won't manifest themselves until a century later: enough time for them and their kids. They don't care about their hypothetical grandkids. When the world starts collapsing in a century, they expect to have machines to fully replace 99% of the workforce: so most of the populace will fight for scare sources of clean water, while the rich would live somewhere in new Zealand, protected by unapproachable army of machines. That's what I think is their plan. However, I also think it's a naive plan.

A very good point, and one which makes the mentioned attitude even more silly.
It's strange to me because it feels like I've been seen articles about the topic for at least a decade, and people just shrugged their shoulders until the polarization from the 2016 U.S. presidential election, the subsequent culture wars, and deplatforming becoming a major tactic used in the culture wars, kicked it into overdrive.

No student learns everything that university teaches; there is simply not enough time. It would be ideal if each student received a perfectly customized curriculum; but that is simply not practical to do. Instead, universities have a modular system; where different students can mix and match modules to cover what they are interested in. Similarly, different majors can mix and match required module to cover the material that is nessasary for said majors.

In the case of subjects with a very large number of students, it is possible to produce specialized modules, so you might have a university offer a separate probability-for-scientists and probability-for-mathematicians classes that it considers to be interchangable, but differs in how it covers the subject/what background it assumes.

Following proper XML spec always led to more problems than what they were meant to solve. Sometimes I use XML, but just the syntax with a more html5 style to it.

Similar to defaulting to error-ing on extra tags, I never got the point of making everything an element and adding extra redundant attributes. That's really just the result of XML that's automatically generated.

Like the `<element... type="string">` in your example of classic XML, why not just use `<a>3</a>` or `<a int="3"/>`. XML proper styles still suggest the classic long/autogenerated form. Writing XML in html5 style like `<my-a data-value="3" />` makes it much friendlier. Or as I tend to use it for various internal protocols to wrap multiple CSV data in a file:

<some-data type"csv" columns="A, B, C">
1.3, 3.4, 5.6
1.3, 3.4, 5.6
</some-data>

Technically That's really just html5 in a file I guess. :-) But html parsers also don't tend to complain about extra tags too.

This is Definitely a new concept for India and will definitely benefit consumers as they will now have greater choice for online ordering of grocery, fmcg and other products at the press of a button.

Lectures in big rooms can be trivially replaced. And, arguably, are improved upon by even a relatively modest digital effort. You get time shifting, acoustics and video can be better, you can rewind, and you can get the best lecturer to do it. 8.01 or 18.01 or 6.001 (Intro to physics/calculus/algorithms) doesn't really change YoY.

You could do that on VHS tape if you wanted to.

The hard part is problem sets, recitations, grading, peers, etc. And MOOCs do very little there. Automated grading is better with programming than it is wirth other things. But it's still just looking at the result.
Question about these hacked accounts: Why pay money for some account like this when Twitter will presumably just return the account to the original holder?

And assuming I'm giving Twitter too much credit: How would one even start to use a taken over account, assuming the new account has its own followers and history, it's not as if one could just change identities and start posting from a new account as onesself. It would be weird to ask all my friends to start following a new account because I've switched accounts?

Sorry, I don't think I've ever really understood Twitter.
