2019-12-26: scraped off some of the likely soap scum from standing bathtub with hard plastic rice cooker spoon.
And do 5 big queries instead of hundreds of smaller ones.
For example, a README.ciro document that references another document saying:
The \x[speed-of-light] is fast.
needs to fetch "speed-of-light" from the ID database (previously populated e.g. by preparsing light.ciro:
= Light

== Speed of light
to decide that it should display as "Speed of light" (the title rather than the ID).
Previously, I was doing a separate fetch for each \x[] as they were needed, leading to hundreds of them at different times.
Now I refactored things so that I do very few database queries, but large ones that fetch everything during parsing. And then at render time they are all ready in cache.
This will be fundamental for the live preview on the browser, where the roundtrip to server would make it impossible
Look at this. You beat cancer, and then you went back to work at the carpet store? Booooh.

How a quartz watch works by Steve Mould (2017)
Source. Mentions feedback loop loop with the quartz tuning fork for the piezoelectricity and an amplifier. Also mentions the choice of 32768 Hertz () as the first power of 2 that is outside of the human hearing range, and then how a frequency divider is used to reduce the frequency to get the second counter.
This form is not really an inner product in the common modern definition, because it is not positive definite, only a symmetric bilinear form.
The list of unnumbered trans-Neptunian objects (TNOs) includes objects in the outer solar system, particularly beyond the orbit of Neptune. TNOs can be classified into several categories, including classical Kuiper Belt objects, resonant TNOs, and scattered disk objects. In 1999, several unnumbered TNOs were discovered, though the specifics of these objects would depend on the naming conventions and catalogs used at the time.
Skathi is one of the moons of Saturn. It was discovered in 2000 and is part of the Norse group of moons, which are named after figures from Norse mythology. Skathi has a relatively small diameter of about 18 kilometers (11 miles) and is characterized by its irregular shape. Its orbit is highly inclined and somewhat eccentric, which is common among the outer moons of Saturn.
As of my last knowledge update in October 2023, Lucien Poirier could refer to different subjects depending on the context. It's important to clarify the context to provide accurate information. 1. **Historical Figure**: Lucien Poirier was a notable French figure perhaps known for contributions in a specific field, but more context would be needed to identify his contributions accurately.

Pinned article: 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!
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:
    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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
