I wish org-mode (https://orgmode.org/) was more popular. It's plain text, but way better than any other competitors.

How is it compared to JetBrains' https://hyperskill.org ? They seems to be competitive products.

PS. HyperSkill's pricing is also more competitive. They offer tons of tracks containing hundreds of coding projects at the price of 240$ per year, while CodeCrafers' charge is 790$ per year.

Oh the PR is so huge. Would this be difficult to review?

The title reminds me of Doctor Who.

It’s not *Higher* math. It’s just normal math.

And this has made flameshot not able to work under Gnome: https://github.com/flameshot-org/flameshot/issues/1910

It's a lot of fun!

Flameshot supports Wayland recently. That why there is a “all major operating systems” in the title of the post.

This article should be written with Rust/Haskell/Scala/OCaml/TypeScript ... or any languages with an insane type system. Anyway it can’t be Go, a language without sum type.

Just personal preference. I made this title by myself other than censorship. Anyway, “fuck” sounds a little rude.

I recommend John Stillwell’s The Four Pillars of Geometry https://www.springer.com/gp/book/9780387255309. This book is suitable for all who want to cultivate a interest in mathematics.

The Four Pillars of Geometry approaches geometry in four different ways, spending two chapters on each. This makes the subject accessible to readers of all mathematical tastes, from the visual to the algebraic. Not only does each approach offer a different view; the combination of viewpoints yields insights not available in most books at this level. For example, it is shown how algebra emerges from projective geometry, and how the hyperbolic plane emerges from the real projective line.

John Stillwell is a great mathematician and writer. You won’t regret reading this.

PS. John Stillwell’s Mathematics and Its History is also worth reading. In fact, the book doesn’t aim to tell the story of mathematics. The book connects and the parts of mathematics with a historical perspective.

MarginNote 3. It is more than reading. MarginNote combines reading, annotating, mindmapping etc. so it's a great tool to read and arrange your hard-to-reading books.
