My HN viewing habit: check frontpage quickly (only the frontpage, rarely beyond that), check "new" for 5-6 pages to see if anyone has posted something cool, and then lastly check "active" and go through every page because that's where the interesting discussions are.
I used to think the frontpage was natural and unadulterated but then I learned that dang, tomhow, et al "curate" the frontpage, so you essentially see what they want you to see, but with "active" there's less of that.
I don't think they curate it. From what I understand it is basically just "hot" submissions. However they do have the ability to bump individual submissions onto the front page if they feel a specific submission might have been of interest to the community but was previously overlooked when it was "new".
If I understand that correctly, then I think that's a nice balance. It means the front page is largely items that the community, as a general, that voted on. But it also gives the opportunity for interesting submissions to have a second chance if they did slip through the system unnoticed.
These banks and consultancy companies just hoover up all the talent and bright minds from our best institutions. You wouldn't believe the amount of Oxbridge grads I've met who now work at McKinsey&Co, Jane Street, etc. This is why we're faltering in STEM when compared to China. Our brightest don't become mathematicians, physicists, chemists, engineers, and so on anymore. Instead they become bankers and consultants at vampiric companies, with the sole goal to make rich people richer.
Was it a typical textbook? I know it was used for a long time, and it's interesting that an ancient book was used in math education, but I doubt it was widespread by the 70s, or even by the time these two Russian textbooks were written.
For me, it's The X-Files, Buffy the Vampire Slayer, The Simpsons and Malcolm in the Middle. Those are the shows I watched as a kid and I'll love them forever.
It is though, the first person who used the 'mowing the grass' euphemism clearly talked about killing kids and preventing Palestinian women to have access to reproductive care (and the fact that it is almost impossible to report a rape if you have no doctor who can confirm it is a very, very nice bonus.)

These should be enough to give you a first and second year undergrad level education in mathematics (minus stats&probability).
