I remember when I was a kid, Kangaroo math puzzles were incredibly fun. I don't know if you can get your hands on some materials, but they were such a blast. https://mathkangaroo.o…

so aliens did build the pyramids!

of course they are. The Chinese team selection tests are notoriously more difficult than the IMO, and they enforce a one-time participation limit. If they were to send 24 people, n…

Yeah, that was a very weird comparison. Not only do those countries send 6 people each, those four started participating in 1959 while US started in 1974 and China in 1985. Though …

There's gotta be something between Satya and "C-tier code out of rural India". There are of course lots of bad coders in India, but there are also many really good ones. And wherea…

aren't most languages invented and initially developed within a private company? Go, Dart, Java, JavaScript, C#, F#, VBA, Kotlin, Erlang, C(at AT&T), Rust (at Mozilla). The list is…

I believe what GP is saying is: coming from python, which uses `and` and `not` and `or` you expect those to be the binary operators in ruby as well. You are then surprised when the…

Kotlin is very ruby-like and performant, check it out. If you don't mind using JetBrains IDEs, I'd give kotlin a try.

`and`, `or`, `not` have much lower precedence than `&&`, `||` and `!` . I would just avoid `and` and `or` in general. For some more explanation see https://graceful.dev/courses/the…

Or it could be a typo (as in man-made) My guess is that they only use Youtube videos that already have subtitles in the target language. But I'm curious to know how exactly they've…

But they don't have the same area. The donut seems to be at least 1.5x larger than the cup (check out the screenshots posted by latexr in another comment. The area covered by the d…

Thanks for the reply and for the screenshots. before writing my initial reply, I went back and tried to get a 50/50 split based on your comment and came up with the same solution. …

Can you explain more? (I might be stupid and don't see some obvious proof of why your approach is correct), but intuitively it doesn't seem that the fact that the cup is symmetrica…

ruby is strongly typed, in that it doesn't allow you to implicitly coerce between types*: 1 + "1" will raise an error. (As opposed to weak typing in C or JS) ruby however is not st…

Leetcode is fine: lots of supported languages, large community, lots of solutions and editorials. Here are some more resources: - USACO: https://train.usaco.org/ and https://usaco.…

Great resource, but it's hard to practice there as a beginner because there are no solutions (unless you solve the problem yourself). So you might have to get comfortable with bein…

Never attribute to malice that which can be adequately explained by stupidity.

Most advice in TFA seems pretty good, but the first point: > 1. If you do Google the question beforehand, delete your tracks afterwards IMO, if you ask me the same question that I …

Do you have any source pls? Who controls the DJI copter drones? Does the plane act as a relay for the radio signals?
