The Capital (Water Margin location) by Ciro Santilli 35 Updated +Created
"The Capital" is what now is Kaifeng in Shandong, and it used to be the capital during the (Northern) Song dynasty.
In the novel it is simply often simply called as 东京 (capital of the East), which is now highly ambiguous term that can indicate several different historical capitals! Notably it is the name of modern tokyo.
Gallium arsenide vs silicon by Ciro Santilli 35 Updated +Created
The Supermen: The Story of Seymour Cray by Charles J. Murray (1997) page 4 mentions:
Cray wanted his new machine to employ circuits made from a material called gallium arsenide. Gallium arsenide had achieved limited success, particularly in satellite communications and military electronics. But no one had succeeded with it in anything so complicated as a computer. In the computer industry, engineers had developed a saying: "Gallium arsenide is the technology of the future," they would say. "And it always will be."
Music of Super Mario 64 by Ciro Santilli 35 Updated +Created
It is interesting how the Etyptian level, Shifting Sand Land, clearly has Indian classical music, with sitar, tanpura and tabla:Apparenty we don't know what Egyptian music would have sounded like exactly.

TODO why is it so hard to find anything non perturbative :-(
On a quantum computer...:

Are we living in the matrix? by David Tong (2020)
Source. Talks about how the Nielsen-Ninomiya theorem means it is impossible to simulate QFT on a computer in the case of a lattice gauge theory.
Digital electronic computer by Ciro Santilli 35 Updated +Created
Unsurprisingly the term "computer" became a synonym for this from the 1960s onwards!
SuperTuxKart by Ciro Santilli 35 Updated +Created
It is a shame, but this game just doesn't feel good. The controls are just not as snappy as Mario Kart 64, the levels are too wide which limits player interaction, and the weapons feel clumsy weak and unexciting. These are all aspects that the closed source smashkarts.io gets pretty well.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!

Intro to OurBigBook

We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    • to OurBigBook.com to get awesome multi-user features like topics and likes
    • as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
