In New Haven CT there's a downtown mall that was converted to an apartment building, but none of the commercial space was left unconverted

It felt like the most oddly gloomy place I've ever seen apartments: https://i2.wp.com/box5497.temp.domains/~betwefc1/wp-content/...

Could you post the link to the degree that you're taking.
It's effective but it sounds like the fear is that the effectiveness is overhyped (says this specifically in the article)... and I think that's a valid concern.

If everyone thinks they can go out wearing a mask and forget about distancing and other measures, then that complicates things. Wearing a mask to go grocery shopping for 20 minutes is also different than say, wearing a mask and sitting in a theater or bar for 2 hours.
The malls are going down because their key tenants are going under. Sears, JC Penny's, Macy's and plenty of small entities.

Malls aren't exciting enough. They're not special enough. It's a 20th Century experience that hasn't been updated in too long. At this point there's no time or money for a makeover. They're too focused on staying alive.
Depends on what you want to do. Cancel culture is alive and well in germany, we have official and legal discrimination against men across the country and the whole stuff is becoming more and more cemented into laws with laws like the ones the parent comment spoke about
Ah ok, I was discriminating between a true multidimensional array and array-of-array (which can be ragged).
I remember Pi in the Sky by John Barrows very fondly. It has more of a focus on geometry and logic.

A Programmer's Introduction to Mathematics by Jeremy Kun is wide ranging and appropriate if there is also interest in programming.

Nature and Growth of Modern Mathematics by Edna Kramer is a wonderful book if history is a passion as well.

Elements of Mathematics by John Stillwell is a broad overview of subjects. It has a crisp mathematical feel to it.

Vector Calculus, Linear Algebra, and Differential Forms by John & Barbara Hubbard is a beautiful introduction to the multi-dimensional aspects, but it is a book that should happen after knowing one dimensional calculus. .

If your child hasn't been exposed to Guesstimation, then a book on that is highly recommended. The book with that title by Weinstein and Adams is a nice guide to investigating that realm.

If the child does arithmetic from right to left, as is sadly too common, the book Speed Mathematics Simplified by Edward Stoddard is a great remedy for that.

Everyday Calculus by Oscar Fernandez could also be worth a look.

Greatest Mistake of Our Time
VirtualBox has improved tremendously in the last seven years. In that same time, progress on VMware Fusion and Workstation has slowed (they got rid of most of the dev teams, if I remember correctly).

I'd recommend just sticking with VirtualBox unless VMware has some feature(s) you need and/or you have the extra money to blow.

You can even start with VirtualBox and move to VMware later if you find a reason to. You can easily convert any existing VMs back and forth, etc.

(I've got a full vSphere cluster here in my home lab and VMware Workstation on my workstation and primary laptop. I've decided that I won't be giving VMware any more money, though.)
I hope the education is free. Because without the human presence, paying $250,000 USD for a university education sounds like a ripoff.

If you're looking for "basic for the modern era", also check out freebasic and appgamekit studio, the latter of which is a descendant of darkbasic and the "tier 1" version uses a basic dialect. What made appgamekit better for me than qb64 or freebasic is the runtime debugging. While qb64 and freebasic compile down to native code, appgamekit uses bytecode in a vm, allowing you to use the same step, watch, breakpoint stuff as quickbasic of old.

> but the history of slavery in the last half-millennium had everything to do with race;

Slaves in Russian Empire were freed a few years earlier than slaves in the USA. There were roughly 5 times more slaves in Russia than in USA, and I can pretty confidently say that zero of them were black. Even if you add ~2 million black slaves from Brazil, the number of black slaves would be dwarfed by the white slave population from Russia.

Based on this calculation, I don't think that your thesis about the history of slavery in the last 500 years holds well.
The princeton companion is nice to have around, but you do not really read it end to end.

Spivak's calculus you bring to the beach and read it between swim and swim.

EDIT: Also, some books by Hilbert are breathtakingly beautiful: Geometry and the Imagination (just the chapter on synthetic differential geometry is worth more than 10 other great books), and the Methods of Mathematical Physics is also great. It begins by giving three proofs of cauchy-schwartz inequality, and then goes on to give several different definitions of the eigenvectors of a matrix. Both of those make great beach readings for this summer.

There's no uncertainty that unfit around the nose masks have giant centimeter squared open gaps. For protection of the wearer they're not good. Objectively in tests with similar gaps the rating is N30-N40.

There needs to be a strong and lasting push for increased N95 mask production or at least purchasing. Pretending that ineffective unfit masks (of any material!) can fill the role of real masks does real damage and needs to stop. If everyone could rotate a set of N95 masks when indoors then spread could really be stopped.

Even a synthetic/cotton/synthetic mask would be quite effective if they'd just incorporate metal nose bridge with foam.
Smash Bros and CS:GO can be great!
Concrete Mathematics by Knuth and Patashnik (already mentioned for u/pmiller2) if the kid likes numbers. That's perhaps the guiding thread of the book -- it's about the beautiful (yet usually very elementary and natural) things you can do with numbers.

Geometry Revisited by Coxeter and Greitzer and/or Episodes in Nineteenth and Twentieth Century Euclidean Geometry by Honsberger if the kid is into plane geometry. It's an idyllic subject, great for independent exploration, and the books shouldn't take long to read. Not very deep, though (at least Honsberger).

Anything by Tom Körner, just because of the writing. Seriously, he can make the axiomatic construction of the real number system read like a novel; open https://web.archive.org/web/20190813160507/https://www.dpmms... on any page and you will see.

Proofs from the BOOK by Aigner and Ziegler is a cross-section of some of the nicest proofs in reasonably elementary (read: undergrad-comprehensible) maths. Might be a bit too advanced, though (the writing is terse and a lot of ground is covered).

Problems from the BOOK by Andreescu and Dospinescu (a play on the previous title, which itself is a play on an Erdös quote) is an olympiad problem book; it might be one of the best in its genre.

Oystein Ore has some nice introductory books on number theory (Number Theory and its History) and on graphs (Graphs and their uses); they should be cheap now due to their age, but haven't gotten any less readable.

Kvant Selecta by Serge Tabachnikov is a 3(?)-volume series of articles from the Kvant journal translated into English. These are short expositions of elementary mathematical topics written for talented (and experienced) high-schoolers.

I wouldn't do Princeton Companion; it's a panorama shot from high orbit, not a book you can really read and learn from.

Buy them 2 books as follows:

#1: your "The Princeton Companion.." or any of the great suggestions that you got here

AND THEN

#2: "Gödel, Escher, Bach: an Eternal Golden Braid" by Douglas Hofstadter. Best if you can get an old, old beat up paper copy at Amazon. Tell him that if he's lucky it will take him a lifetime to actually "get it". Tell him to keep the book in sight, bedroom, studio.. why not, bathroom. And to just read it not sequentially but at random. That is the best present to a mind thirsty for knowledge.

He might not appreciate it right not, he will appreciate it 30 years from today, if he's lucky.
Obviously it would be a win for the Olympics to include Fortnite. After all, Fortnite makes more money than the Olympics and is more popular than almost all Olympic sports. It would provide inroads to the more valuable younger audiences that the Olympics are starting to lose. But why would Fortnite want to give up control of its product to the Olympics?
I really look forward to seeing what can be done with Postgres's pluggable storage backends that were recently added. It seems that some of the issues with treating a table as a queue could be mitigated with special storage backends designed for such a job.
Better-fitting masks made of non-woven cloth might help, but the focus on N95 and the confidence that "spread could really be stopped" by wearing them is exactly the kind of overconfidence the article warns against. There's no known evidence supporting the idea that good masks are a silver bullet.

Ooh, this reminds me that I saw a file being included straight from github.com on flyporter.com (Canadian regional airline)

Actually, extremely weirdly, they didn't include the "actual" file (the raw version of it) but ... they included the github page in the <script> tag...??

Go through a checkout on flyporter.com (use dates > Aug 31st as they're resuming service then) and you'll see

`<script src="https://github.com/furf/jquery-ui-touch-punch/blob/master/jq...

>What would you have appreciated having been given at that age?

I remember getting God Created The Integers when I was a teenager and... not finishing it. I also got a copy of Brown & Churchill's Complex Variables and Applications and spent hundreds of hours on it. As a teenager, I preferred textbooks with problem sets to popularizations. (I still do.) Of course, this was [complex] analysis, so it doesn't qualify.

One book which is fully technical but also entertaining by way of the subject matter, and which was inspiring to me around 14-15, was Kenneth Falconer's Fractal Geometry:

https://www.amazon.com/Fractal-Geometry-Mathematical-Foundat...

Of course, at that age, I didn't understand what Falconer meant by describing the Cantor set as "uncountable", or what a "topological dimension" was, but I was able to grasp the gist of many of the arguments in the book because it is very well illustrated and does not rely too much on abstruse algebra techniques. Some people don't enjoy reading a book if they don't fully understand it, but I liked that kind of thing. As I got older and learned more, I started to be able to understand the technical arguments in the book as well.
I like providing some context that prompts the model for a list if I think I might need a few candidates. "We discovered a series of journals by several authors in the cabin. The authors' names were:" worked pretty well.
The remote control and whiteboard in Microsoft Teams are better in my experience.

In fact, Teams seems to have better (although still not good) UX and connection reliability as well, at least for corporate meetings. There’s generally no P2P possible from behind “enterprise” security gear or VPNs, so Zoom suffers a bit falling back while Teams blissfully just works via TCP/443 or a browser.

> premise that everyone has time for side projects. From that point I think about it as a bias.

Yes. In many plausible scenarios hiring based on side projects will discriminate against people who don't have much free time: people with responsibilities to look after young children or otherwise care for family, people who never had a job that pays enough to only work 40 hour weeks & who have to work multiple low paid jobs, etc.
We used those as well.
Heh, yeah, it's a pain in the ass. But blame Google and other greedy un-trustworthy mega-corps who data mine.
> My understanding is that there's no real distinction between "sum type" and "union type" as such.

There’s a difference in the ambiguity — or lack thereof — which is the purported reason why go could not have sum types.

> But in Rust, as I understand it, enum variants aren't actually types.

That’s correct. They’re just constructors for values if the enum type.

> It's just too late for Go to do anything here, I think. Zero values permeate the language. For example, consider structs. It's normal to do

It’s not too late for anything. Existing types do not have to change and don’t prevent adding new non-default-able types (which would be transitive).

Those types, with those new guarantees, would not allow for the magical zeroing and zero-extending of existing types but they would not break anything.

An opt-in strategy has some challenges here as the data may become biased a cohort of users and you wouldn’t be able to tell whether rejections are due to discrimination or the natural course of business.

The GEOM subsystem is FreeBSD is an example though that sometimes the world changes in a way that you can't accommodate and you have to go do a big bang reset.

It’s winter here - I’m pretty sure that firewood bought by “thrown” volume uses the same maths. You stack it and it all vanished.
Not at all. My own recommendation, God created the Integers, isn't a math textbook. I doubt Hofstadter himself would claim GEB had a point - it was more of an intellectual fugue put to paper. If GEB was a novel it would be more along the lines of Finnegan's Wake than Les Misérables, and I would never ever give the former to a teenager.

All the major incidents with nuclear power are despite dozens of safety systems, redundancies, clever designs etc.

This is because nuclear power is tightly coupled and complex. Humans have never mastered such systems. We have them and we accept they fail sometimes (eg fires at conventional power plants: 200 plus years of engineering and they still happen). But with nuclear that isn't an option.

This is why people are unconvinced by clever new fuels or "it's totally guaranteed this time" engineering. You can't fix a systems/human nature problem with new fuel cells.
On the contrary, there's actually very little evidence that masks are effective for the general public. Particularly for cloth masks, the evidence is essentially non-existent. You're citing an article by Jeremy Howard, who is quoted in the OP, and whose opinion is directly rebutted.

Michael Osterholm of CIDRAP has written a rather scathing summary of the data for cloth masks, and the political and social machinations that have gotten us where we are. He calls out Jeremy Howard as a particularly vocal spreader of scientific misinformation on the topic:

What confuses me is why so much scrutiny is being placed on the practice of wearing a mask. It just hardly seems like much of an inconvenience. And common sense dictates pretty convincingly that it must have some benefit, however small. So then why so much effort into deciding if it works or not?

I suppose there are two answers to that question. One, health officials want to know if masks give a false sense of security so they can spend their time promoting measures that will actually make a difference. Two, folks just want a reason to avoid the minor inconvenience or, worse, have been led to believe that mask mandates seriously impinge upon their rights. My concern is that the most common answer is the second and articles like this only serve to confuse people at a time when we need to accept that we must make small sacrifices to solve this problem.

Yes! I noticed the next time I launched the YouTube TV app they added a screen I've never seen before where it reminded me how much value they were providing (basically the DVR) and showed me a list of shows to add to my unlimited DVR.

I agree the "unlimited" DVR is nice but even then it's not truly unlimited and it doesn't give me the part of unlimited that I'm interested in. I don't need unlimited shows saved for a year, I want to save a few things until I get to them or the odd rare special thing I want to save forever.
Which product comes with “artificial limitations” that force you to give Apple more money?
The actual fear should be from people who dont wear masks, dont wash hands and generally act like covid-19 is a hoax.

It does not even matter whether the non-mask wearer is not wearing it because he believes mask is not effective, mask is not needed due to covid not existing or mask is sign of being fearful and one gotta project bravery.

Mask wearer who skipped washing hands once or approached someone 1.5 meters is still good.
The problem which TaBERT supposedly can solve is speed of this process, you can have hundreds of tables, with dozens of columns with many unobvious relationships, and constructing query manually can take lot's of effort even using UI automation. And the idea is that you have some system, which creates this query instantly following short description.
