The bullshit skepicism should usually be identifiable by applying the same set of rules to evaluate its claims. Take the claim that Ivermectin was effective in treating COVID. Some doctors did support this, but that's Argument by Authority, and probably also Statistics of Small Numbers if not several others.
Because complex numbers make the fundamental theorem of Algebra nice and simple rather than complicated and ugly. In turn, this makes the spectral theorem of linear algebra nice and simple rather than complicated and ugly. In turn, this makes a bunch of downstream applications nice and simple rather than complicated and ugly.

You will get a feel for this if you work Axler's problems. More importantly, you will gain an intuition for the fact that if you turn up your nose at complex numbers while going into these application spaces, you are likely to painstakingly reinvent them except harder, more ugly, and worse.

Example: in physics, oscillation and waves A. underpin everything and B. involve energy sloshing between two buckets. Kinetic and potential. Electric and magnetic. Pressure and velocity. These become real and imaginary (or imaginary and real, it's arbitrary). This is where complex numbers -- where you have two choices of units -- absolutely shine. Where you would have needed two coupled equations with lots of sin(), cos(), trig identities, and perhaps even bifurcated domains you now have one simple equation with exponentials and lots of mathematical power tools immediately available. Complex numbers are a huge upgrade, and that's why anything to do with waves will have them absolutely everywhere.
I actually took that time from [1] which was set in 2017.

If you prefer, let's consider California, population 30 million to Scotland's 5 million. According to [2] for the "Boys 100 Meter Dash Varsity" 10.7 would put you among the 20 fastest in the state, although it wouldn't quite get you into the finals (which needed a time of 10.63)

Fastest 20 in a state of 30 million doesn't sound "pretty achievable for someone who spends time at the sport" to me.

> Not sure what line of work you are in, but are you willing to answer endless emails and or voice mails from customers, all for free?

It's common practice to answer emails and take calls from customers and not charge them for it in many industries. If you have 3000 patients, and you spend 3 minutes/patient/year on these interactions, then you spend ~30 minutes a day answering emails or leaving voice mails which is pretty standard.
If you’re throttling, then your database can’t actually keep up with broadcasting changes. Throttling only helps ensure the system keeps working even when there’s a sudden spike.

Batching only helps if you’re able to amortize the cost of notifications by doing that, but it’s not immediately clear to me that that there’s an opportunity to amortize since by definition all the book keeping to keep track of the writes would have to happen (roughly) in the synchronous write path (+ require a fair amount of RAM when scaling). The sibling poster made mention of taking read / write sets and doing intersections, but I don’t think that answers the question for several reasons I listed (ie it seems to me like you’d be taking a substantial performance hit on the order of O(num listeners) for all writes even if the write doesn’t match any listener). You could maybe shrink that to log(N) if you sort the set of listeners first, but that’s still an insertion speed of m log(n) for m items and n listeners or O(mn) if you can’t shrink it). That seems pretty expensive to me because it impacts all tenants of the DB, not just those using this feature…
What do you mean funded by donations? People making educational YouTube videos have their income from YouTube advertising and Premium subscribers. People having utility from their videos should pay for them.

I find it incredible that people accept and support enormous amounts of tax money from workers go to pay for worthless schools, while at the same time they are grinding their teeth at the suggestion that they pay a few dollars for incredibly well made educational videos.

Why does the screeching teacher or professor deserve a high monthly salary, good job security and a good pension, while the person making educational videos that improve people's lives all over the world deserve to have her videos pirated by hackers?
Still a nice interactive web site!! I did something similar when applets were added to Java 1.0 beta, so many years ago. I had an AI tutorial powered by applets.

The Blue Ocean strategy is choosing a specific market segment underserved by your direct competitors and refusing to compete on the product attributes that your competitors are emphasizing, not just "trying something new".
The "their critics just did not understood/read the books" defense is usually a pretty bad sign.

In all subjects, the majority is always rather "moderate", and if few persons twist the words, there is even more persons to consider that these interpretations are unfair, and emit more nuanced positions. If you end up having to systematically say that all her words are always twisted all the time by the majority of people not agreeing with her, it's way more probable that she indeed said things that were indeed controversial. Sometimes, people like her will indeed say something that is objectively controversial, then say something different, and then will point to the something different thing to try to discredit their detractors. Again, this is a red flag that means this person is not bringing anything of value to the debate (and again, if some elements are indeed of value, these elements can be brought forward by people not having these counter-productive and anti-intellectual behaviors).

You say "her work is meticulously well researched and she takes a satisfyingly rational and critical approach in elucidating her viewpoints". But even looking at people who were rather positive about her books, the main critics that they had were that there was not much references, that there was a lot of anecdotal elements and that the view she brings is pretty one-sided. These elements from people who liked her books.

So, reading your comments, you, random person on the internet, it looks like that what you explain is less compatible from the reality I observe somewhere else than the other commentator that you pretend is misguided (it does not mean this other commentator is right, but at least I see less clues that they are biased than clues that you are biased). Thank you from your contribution, you just reenforce the idea that there are people who will depict her work and position in a misguided manner.

in tech surveillance, the idea is that you CAN be watched all the time. Information gleaned is added to a dossier, which can be reviewed later.

I think this kind of stuff causes a terrible conformance.
If you can't explain how the statement could be falsified, at least in principle (although it may be not practical to do so), then you are admitting that reality will always be the exact same regardless of whether your hypothesis is true. And in that case, it's really not useful or meaningful for any sort of reasoning at all.

A concept which will in no way ever make a difference, is meaningless.
Uhhh what?

TikTok makes money via ads and in-app purchases. How do you think TikTok makes so much money? How do you think YouTube should make money storing and serving petabytes of high quality video?
I think it's the same reason why negative numbers were invented: It lets you do more with algebra than you could before (some of which, like raising something to a power leading to a sine wave is pretty weird, but turns out to be useful in engineering, etc.), and everything else still "just works" the same way as before.

(Admittedly the applications of negative numbers are much more obvious.)

> Does anyone know any other good resources for learning calculus at home?

Professor Leonard:

Calculus I - https://www.youtube.com/playlist?list=PLF797E961509B4EB5

Calculus II - https://www.youtube.com/playlist?list=PLDesaqWTN6EQ2J4vgsN1H...

Calculus III - https://www.youtube.com/playlist?list=PLDesaqWTN6ESk16YRmzuJ...

I consider him one of the best lecturers in math education, at least for these subjects. And in particular because he is very detailed in his explanations. He points out that most students who struggle with Calculus struggle because they (never mastered | forgot | whatever) their basic Algebra. So he does a very thorough job of explaining all of the subtle algebraic manipulations that go on as he works through derivatives, integrals, etc.

TBH, I think a person who wanted to learn the equivalent of high-school algebra could just about doing it by watching his Calc I series... and treat any Calculus they learn as "found money." But assuming you remember at least a little algebra and really want to learn Calculus, I think he's one of the best at teaching it.

Note that most of his lectures are live lectures to an actual class, so IMO the best way to approach it is to pretend you're right there in class. Listen, take notes, and then when he puts an example on the board pause the video and work through the example. Just restart the video when you finish the problem or if you get stuck.

If you want to work additional problems, go on Amazon or Alibris or whatever and buy a cheap used copy of one of the enormous Calculus books, and/or a Shaum's Outlines book on Calculus, or one of those "1001 solved problems in $SUBJECT" books... or some combination of all of the above.

Also as a side-note, speaking for myself, I find that I can follow his material find at 1.25x speed, so I pretty much always watch on 1.25x. I could probably manage 1.5x if I really tried, but the time savings from just doing 1.25x is enough to make me happy. YMMV, of course.
Certainly useful for thinking, but its lack of falsifiability, predictive power or validation is indeed why there's so much controversy around it and why it remains a hypothesised model rather than widely accepted scientific fact. The best you can do is test the assumptions of the model itself, or its constituent terms.

Probably not the best example since once a bridge is built you can immediately use it, the benefits don't only start rolling in after a 100 years. Making sure something lasts is correlated with natural disaster safety margins anyway so if it has to be built to survive near term extremes it'll generally also survive a while as a side effect. Older constructions also seemingly last longer through survivorship bias and the lack of computer modelling at the time meant that safety margins had to be higher.

A better example are maybe tree avenues that take decades to grow into anything useful, or maybe long term river redirection projects or reactors. ITER's still in construction after 16 years. But there's just about nothing we do that would take more than a few decades to start showing returns.

Perhaps you meant to day "science doesn't work by p-hacking and data falsification". The great thing about science is that it involves a process of building models and hypotheses, and then running experiments to produce results that support the models and hypotheses. To the extent that p-hacking and data falsification produce results that are not correct, longer term they will have a difficult time distorting our understanding of the underlying phenomena. Short-term, certainly they can be distracting, but we care about reproducibility because scientists are constantly trying to reproduce (possibly by building on older) results. Results that cannot be reproduced do not contribute to science.

Is there a talk you can point me to?

There’s several challenges with this approach that come up for me (which unless I’m mistaken is the naive approach of checking each write against a notification set).

The first is that maintaining the read set seems very expensive since it scales with the number of live queries installed. In a multi tenant DB, that seems tricky to manage in terms of memory used.

The second is that the computation of intersection with a read range seems potentially very expensive. Imagine you have a string column. You now have to do a string comparison for every insertion that might hypothetically match the query.

Finally, computing that read set correctly seems challenging (as you mention) and it’s not immediately clear to me it’s always tractable (eg could you do this with arbitrary complicated joins?).

Additionally, in your description, each write has an implicit table scan to do the select to find the intersection. That will tank write throughput even for small total intersection sets (eg there’s a reason LSM databases do deletes by inserting a tombstone instead of checking whether the data exists first, same with the merge operator in RocksDB - a db read in the write path significantly kills performance)
I've never seen database that either (a) allows you to create that many schemas at all or (b) doesn't become less stable because of it.

One example of this is that the database may create a directory structure per schema which will then result in file system performance degradation or hitting end user limits.

When I have sent a message to my provider it has been because I had a follow up question because the direction given during a visit was unclear once it came time to implement it or there was an issue with a prescription (for instance a particular drug ended up not on my formulary and an alternative needed to be prescribed). The last time I sent a message is because the doctor said he was prescribing a medication and it appeared in my post visit summary but the prescription never was submitted.

>If we want to falsify, we should ask questions like: Was there a time in the past when the atmosphere contained even more CO2 than it did now? What was the temp and did life survive?

Do you believe that question isn't already asked and answered? Just going off the top of my head, I understand historical considerations to be a routine observation as part of your typical course or even presentation on the history of climate change. If you believe this counts, then your answer to your own question about the falsifiability of climate change is yes.

I also don't think that's the only kind of example - I think the routine things talked about on a day to day basis, including year by year and decade by decade temperature predictions would qualify, and these data are quite frequently discussed and quite visible.

I also also don't think the distinction between "evidence in favor" and "attempts to falsify" makes a whole lot of sense. These are two different sides of the same coin, and evidence in favor of something is the same as surviving a test of falsifiability.
