Unfortunately Bourbakism polluted teaching of Mathematics in Europe c.a. 1960s. With visible effects. Except for Eastern Europe were it was opposed by Arnold.

> These discoveries of connections between heterogeneous mathematical objects can be compared with the discovery of the connection between electricity and magnetism in physics or with the discovery of the similarity between the east coast of America and the west coast of Africa in geology.

> The emotional significance of such discoveries for teaching is difficult to overestimate. It is they who teach us to search and find such wonderful phenomena of harmony of the Universe.

> The de-geometrisation of mathematical education and the divorce from physics sever these ties. For example, not only students but also modern algebro-geometers on the whole do not know about the Jacobi fact mentioned here: an elliptic integral of first kind expresses the time of motion along an elliptic phase curve in the corresponding Hamiltonian system.

Surely Google has to know how bad this is. Why have they not changed it? It makes no sense to me. It is so frustrating how slowly these big companies move.
I think cheating in most science classes is still not easy. The killer is the short answer section. You would waste a lot of time searching for an answer, and if the professor made their own questions you will need to take some time to synthesize bits of information from here or there into an actual answer. Even referring to your notes or lecture materials will chew up valuable time. Sometimes even if you do know everything you are working till the bell.

But if you do have repeated questions, there is software that will basically grep the internet for you to catch plagerism. All the students know that going in, so copy and pasting is no go. Sharing answers can land you in trouble if two students don't rephrase their answers well enough.

All of this can get you kicked out of college and potentially ruin your life with that mark, not to mention the money spent. Still, people do get caught cheating with those risks even before the pandemic.

> US requires naval power to project power into the South China Sea, China doesn't

I understand your point better now. Thank you.

> Without naval power, China has almost uncontested control

The United States has bases in the region. Large bases. They're not configured to pack a strike group's firepower. But there's no reason they couldn't be.

> hypersonic antiship missiles, for a great many reasons, only work very well against large, slow-maneuvering ships

Large, slow, surface ships will go the way of the battleship when hypersonic anti-ship missile technology matures. (Unless missile defense does something unexpected.) That doesn't mean other modes haven't been discussed. (Swarms being the concept du jour.)

> offensive options are more than sufficient using purely air and missile power over the South China Sea

Planes and missiles don't hold territory. Denying large Chinese ships their coast significant curtails their force projection capability onto their neighbors.

Surprisingly, I stumbled across a result that seemed similar yet weirdly different: https://twitter.com/theshawwn/status/1176070857468329984?s=2...

I take the FFT of the phase component, which is very similar to ACF; it’s the FFT of an FFT, but preserves phase. It even takes abs(), which might be mostly equivalent to your squaring operation.

Weird. I am really not trying to claim that I discovered ACF — quite the opposite. My result was shockingly different to what you found, even though the operations are so close to identical.

I think phase is extremely important in visualization. You can see why here: https://twitter.com/theshawwn/status/1176070853819342848?s=2...

You’ve come up with one of the most gorgeous visualizations I’ve ever seen for signals in general!

One way to incorporate phase: turn the angle into an x,y coordinate using atan2, then shade red and blue based on x and y. E.g. x of 1.0 is “full red”, x of -1.0 is no red; ditto for y, but with blue.

The other trick I used was to un-interleave the lines. Basically I noticed that every other line has a strong correlation; therefore drop every even numbered line to remove the aliasing artifacts. Then suddenly you get nice and smooth phase interpolations.

I'm very curious about the type of math you have learned this way. Every math class was heavy on repeated exercises and memorization, but real understanding didn't come until outside of class (or after the semester) where reflecting on larger ideas lead to mental connections and analogies. I'll freely admit that I have to look up the integral/derivative of simple trigonometric functions every time, despite every attempt from the instructor to hammer those in during Calc II. Doing hundreds of integrals on homework and study guides kind of worked to learn those rules, but only imperfectly and temporarily. Doing hundreds of exercises over and over again has been even less useful for my later math classes. If some proof doesn't make sense, the next step is not to go through 100 examples, it is to break down the pieces into logical structures that are recognizable. All real understanding of math fundamentally works this way. (disclaimer, my math past calc/linear algebra has been in CS classes, so I'm definitely open to hearing how those from other backgrounds or those with more formal math education disagree with me)

If you think you understand some mathematical rule, but can only show 100 problems from memory, you don't actually understand it that well. If you can convincingly show why no counterexample exists, then you understand it in the strongest possible way.
>I'd like a mail client as capable as mutt, but that also works whether I'm online or not, handles mail sync automatically in the background while I start processing those mails, lets me browse and search and draft responses offline, and has a built-in idea of "has that mail been sent yet?" rather than just saying "sent" the moment a mail goes into another queue the client doesn't manage without giving any status for when it actually gets sent. And all that while also leaving mail on the server so that other mail clients such as K-9 mail on my phone (which can do all those things) can also process mail..

FWIW aerc does have all this built-in, but also offers the possibility to just hand off responsibility to external programs. As far as I'm concerned, I use the built-in email sender. Unfortunately, the built-in emails fetcher does not work well with poor internet connection or offline. That's why I use offlineimap to sync maildirs every 5 mins, and notmuch is just the icing on the cake for fast search/indexing.
Actually Neapolitan pizza is 170 years old. Flatbreads have been around for millennia.

So pizza in Naples is only slightly older than pizza in Little Italy in NYC. It arrives in USA in 1890s

The main problem is that in the great american convenience rush of the 50-s, 60-s etc the tradition is overwhelmed by mass pizza from the chains. And what becomes mass pizza (especially delivered) is inferior product. We have lower baking temperatures, start pumping the dough with oil, sugar and whatnot to get some browning. To compensate for lack of flavor in the dough you start putting all kinds of toppings on top and too many of them. Upping the calories to insane levels to compensate for their flavorlessness.

I think that when people dish out on American pizza they don't mean NYC, New Haven, Chicago or Detroit styles but Dominos and Pizza Hut at their worst.

What about bio warfare. Covid showed how effective it can be. Crippling sabotage attacks against infra as well.
unique_ptr<Blah> foo = make_unique(...);
unique_ptr<Blah> bar = std::move(foo);
// foo is now effectively destroyed as part of the move;

foo->something(); // Will error, probably seg-fault. Foo is now "empty"

The value foo used to point at is preserved. But foo itself was destroyed from the std::move(foo); The foo->something() is almost certainly a null-pointer exception or seg-fault in any sane implementation of C++11.

---------

Example 2:

int main(){
vector<int> foo = {1, 2, 3, 4, 5};
vector<int> bar = std::move(foo);

cout << foo.size() << endl;
cout << bar.size() << endl;

return 0;
}

Notice: foo.size() is 0. The foo-vector was DESTROYED by the std::move(foo);.
> One more sad step towards de-humanizing the enemy.

Much worse than that; it's one more step towards screening people from the monstrosities of the war, creating therefore a culture that endorses it because any negative effects are hidden. Families are often opposed to war because they know some of their kids won't make it back; that's a powerful deterrent and is the reason why after a while showing soldiers coffins was forbidden to US TV networks during the last Gulf War: they recalled the protests during Vietnam after it became clear that soldiers weren't taking a walk in the park down there.

Now if we make it certain for one side to never lose any soldier because every action is being performed from safe distance by a drone pilot, war suddenly becomes a videogame in which one side cannot lose anymore, but more importantly that same side won't have any negative feelings associated to the war because it doesn't bring any suffering.
This is the recipe for creating a state of eternal war, and I'm strongly opposed to that. I want all sides - including mine - to experience deaths and mutilation, grieving families, babies who will never know their parents, etc. If we take those away, we take away all reasons to not want wars.

Yes, also, consider how death is sort of a taboo subject. I think the simple act of reaching out to someone because of this death thing which is unknown and terrifyingly so to some is worthy and grand. To hell with what they say but look at what they did: they reached out to you. Many have no one reaching out to them. And sure, we all navigate reality our own and we go into the grave alone but reaching out to someone is a sort of illustration of this "love of thy neighbor" idea which says, "What are you going through?" As naive as that sounds.
This piece is so full of opinion-loaded words it just becomes untrustworthy. In fact, the choice of words sounds suspiciously like those corona denier articles floating around, expecting the audience to just eat up their words and copy the intended opinion. Now I believe the EFF to at least be fighting for a good cause (though its methods are sometimes criticised), but articles like these make it harder to believe.

I see that the central claim is correct (the formerly free ink plan now indeed costs $0.99 per month on HP's website). However, had they taken a more fact-based, and less opinion-based, approach to writing the article, I would actually have more than skimmed it.

EDIT: My main frustration is that I expected "us" to do better than the manipulative text that large companies continuously put out. I was disappointed.

Nice source there.
In all my 300 student classes, we had recitation sections with maybe 20 students to a TA or teaching professor to go over the homework/take quizzes/serve as extended office hours beyond the time the professor and this TA already made available themselves every week. It wouldn't be much more work for the TA to give each student in their section a 1 on 1 hour meeting over the course of a week or two.
Is the freedom of speech as stated in law enough?
I can imagine that a lot of journalists are afraid to say what they want (or need) to say. The thread of losing the job is possibly a great burden in the pursuit of truth.
We should enable some sort of financial independence for journalists to give them every reason to speak and write truthfully.
A young and starting journalist needs a job at an established organization and is therefore bound to theire agenda.
Muslim and Jewish dietary law are both interpreted in various ways by various authorities (and, of course, adherents follow those laws to various degrees of strictness). So any blanket statement on the subject is going to be incomplete.

Under the strictest rules for each, halal meats cannot be kosher and vice versa, because the slaughter must be carried out by a member of the religion. The physical requirements for the initial slaughter are essentially identical. But it's not uncommon for Muslims to view kosher meat as acceptable, at least as an alternative (and there's scriptural basis for this).

The reverse really isn't possible because there are more restrictions on how kosher meat is handled after slaughter , most notably the removal of certain fatty tissues, nerves, and veins. More info on that here:

I am not arguing the merits of nutrition. My point was vegetarian is always a tiny bit cheaper than poultry in the menu.
I think that’s totally true in cases where the market is a rapid and reliable feedback mechanism. It’s a delicate balance, and I can see how a large bank account leads to avoiding the hard choices or the rapid iteration necessary to find a good product market fit. See Quibi.

However,in some industries, the relationship isn’t quite as straightforward. I work in biotech, so in my case the market is realistically not going to be part of the story until we have a drug, which will be a long time from now. Until then our “market” is pharma partnerships or financing opportunities, both of which are only partially rational exercises in value determination. For us, lots of money is helpful to weather the storm and really build a great technology. There’s also little risk that if we treat a disease, we won’t have people want the treatment, so product market fit isn’t quite the same issue.

That said, it’s easy to lose focus by forgetting that the tech isn’t the point (finding a good drug is) and that we can’t try all options. But those are in our control.

A group of contemporary Italian intellectuals set up “Nicoletta Bourbaki”, which is “an inquiry group devoted to the merry debunking of right-wing historical revisionism, history-related fake news and neofascist ideologies. [...] The group comprises historians, researchers in various disciplines, writers and activists. The collective pseudonym is a transgender tribute to the ensemble of mathematicians collectively known as «Nicolas Bourbaki»” [0]. The group published quite a bit of material about the manipulation of Wikipedia entries related to WWI and the Italian Eastern border, and other false historical memes being peddled online.

Yeah, I have slow hand writing. In one class I took a midterm and got marks for every question I answered, but ended up with a low C because I couldn’t physically write fast enough to finish the test. I thought that was ridiculous, went to the office of disability and went though the process to get an accommodation. I got to use a laptop on the next test and got an A instead.

I’m sure there are some exceptions, but anything but the most generous time limitations in academic courses don’t seem to the improve the measurement of anything meaningful.

I suspect they would have limited usage - both from the legal concerns/lack of utility but also because the obvious counters would be even more readily available - outrange the thing. Assuming it is relatively precise instead of carrying a kilogram of antimatter or something absurd.

The situation is 'very high information entropy' in the sense of it is a combination of both requiring both high technology proliferation and prosperity at the same time as severe and sustained instability for it to become remotely acceptable as a status quo instead of "National Guard? We need artillery on this maniac going around with a death drone. How the hell did he get it in the first place?" Theoretically a dual use guardian drone could say work for digging someone out of a collapsed building quickly which could also be lethal if misapplied but that is getting into 'keeping rattlesnake anti-venom in your pocket all times in Canada in case you get bit by one escaped from the zoo or potentially illegal exotic pet trade' levels in terms of effort and expense vs returns in safety.

That was certainly a problem in person too. At my undergrad, for larger exams you would just pass your ID down the row to the person in the aisle and a TA would collect them all then check everyone in. Wouldn't be hard to just hand your ringer your ID to pass on up. Not unusual to look nothing like your freshman year ID photo in person.
unique_ptr's destructor happens to do nothing in a moved-from state. The fact that some types behave this way does not mean moves are destructive. They're still non-destructive. Indeed you're still supposed to call the destructor after a move, and the destructor very well _could_ do something in general. It's just that it doesn't happen to make any difference for typical implementations of some types like unique_ptr.

In fact there are people who have wanted destructive moves in C++, because they found the current non-destructive moves inadequate, but I don't believe the feature has ever been added. Look up destructive moves to find discussions on the issue.
If they bend the truth to fit their agenda, then yes.
