Late reply, but Gelfand's geometry textbook was published [0] in 2020. I think it was completed by his colleagues after his death in 2009. The calculus [1] and combinatorics [2] books are also in print.

I think part of the point of this brochure is to think about the problems intuitively in the context they are presented. So in the first problem it's just kids trying to buy their first book, it would be silly to think Masha had a fraction of a kopeck (assuming you understand what a kopeck is, I really think it should have been translated as cent) and that the answer could be in range [7, 8). This may be what he talks about when he says that many academics fail at these problems.
Similarly, in problem #2 the cork indeed costs 0.5 kopecks but in this case we're just thinking about cost conceptually, not in terms of how much money a person actually has on hand.
Thank you for that link! I can read Russian and that version is much clearer.
Safari 14 has resolved an inconsistent, tedious bug I kept experiencing (most often on reddit): changing the URL query parameters in the address bar and hitting return immediately resulted in the page merely being reloaded. Had to wait a solid second or so before hitting return to have a decent chance of getting the correct page.
I've experienced something similar before Safari 14: when opening Safari for the first time and quickly pasting the URL to the address bar and hitting Enter, the URL would just disappear and I'd hear a bell sound. Had to wait a second to paste the URL and have it actually go to that page. These little things contribute to a general feeling that the browser is not polished enough for everyday use.
A few things that kept me from using Safari full time (instead of Chrome) last time I tried it:
- On my 15" Macbook Pro (mid 2014), when you speed up videos in Safari the sound is distorted and weird, while in Chrome it sounds properly sped up. I use this a lot when watching educational videos.
- Youtube videos max out at 1080p.
- While there are decent ad blocking extensions, they're not as good as uBlock Origin.
- Web pages are fast and smooth, but the browser UI doesn't consistently feel as quick and snappy as Chrome.
- I once saw some rendering bugs when loading old reddit -- parts of the page were black.
This was Safari 14.
Yes, it's been automatic in Chrome Canary, so it's probably gonna stay that way.
1. The app reliably crashes if I just tap on the screen and then click Done.
2. Why does it need registration? At this point I don't see any benefit from it.
3. Is there a way to delete videos? Or the whole account? Do the videos get deleted automatically after some time?
4. Is anything uploaded before the Done button is clicked?
Why do you assume that it's about discipline being for pushing through mindless tasks? What if my discipline is to do 3 hours of creative thinking each morning?
The point here is that you pick the things that are important to you (not mindless tasks) and start doing them every day no matter what and keep showing up even if you don't feel like it or know that the result won't be that great. Because the main goal is to build the discipline and then great things come out of it.
This is very true. I realized this a few weeks ago myself. I've seen a video on youtube where a guy talks about discipline being greater than motivation - https://www.youtube.com/watch?v=vMnMp-d5pKs
I like the idea when he talks about 'becoming a machine', that attitude can help in many situations.
