Maxwell's equations require special relativity Updated +Created
When charged particle though experiment are seen from the point of view of special relativity, it becomes clear that magnetism is just a direct side effect of charges being viewed in special relativity. One is philosophically reminded of how spin is the consequence of quantum mechanics + special relativity.

Group all SQL queries together Updated +Created
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

At github.com/cirosantilli/china-dictatorship/issues/738 a user made a comment about gang raping my mother (more like country-raping).
As mentioned at github.com/cirosantilli/china-dictatorship/issues/739, ally Martin then reported the issue, and GitHub took down the wumao's account for a while using their undocumented shadowban feature, until the wumao edited the issue.
Based on the discussion with Martin, I then recommended at github.com/cirosantilli/china-dictatorship/blob/41b4741a4e6553f44f5f1ef85cf63c55eb7b8277/CONTRIBUTING.md that we do not report such issues, and that GitHub do not delete such accounts, with rationale explained on the CONTRIBUTING.

Photoelectric effect Updated +Created
No matter how hight the wave intensity, if it the frequency is small, no photons are removed from the material.
This is different from classic waves where energy is proportional to intensity, and coherent with the existence of photons and the Planck-Einstein relation.

Now that we can reliably split files at will with \Include, I finally added this feature.
This means while developing a website locally with the OurBigBook CLI, if you have a bunch of files with an error in one of them, your first run will run slowly until the error:
extract_ids README.ciro
extract_ids README.ciro finished in 73.82836899906397 ms
extract_ids art.ciro
extract_ids art.ciro finished in 671.1738419979811 ms
extract_ids ciro-santilli.ciro
extract_ids ciro-santilli.ciro finished in 1009.6256089992821 ms
extract_ids science.ciro
error: science.ciro:13686:1: named argument "parent" given multiple times
extract_ids science.ciro finished in 1649.6193730011582 ms
but further runs will blast through the files that worked, skipping all files that have sucessfully converted:
extract_ids README.ciro
extract_ids README.ciro skipped by timestamp
extract_ids art.ciro
extract_ids art.ciro skipped by timestamp
extract_ids ciro-santilli.ciro
extract_ids ciro-santilli.ciro skipped by timestamp
extract_ids science.ciro
so you can fix file by file and move on quickly.
This was not fully trivial to implement because we had to rework how duplicate IDs are checked. Previously, we just nuked the DB every time on a directory conversion, and then repopulated everything. If a duplicated showed up on a file, it was a duplicate.
But now that we are not necessarily extracing IDs from every file, we can't just nuke the database anymore, otherwise we'd lose the information. Therefore, what we have to do is to convert every file, and only at the end check the duplicates.

--format-source Updated +Created
Added ourbigbook --format-source automatic code formatting. I implemented it for the following reasons:
  • I want to do certain automatic modifications to source code on web, e.g.:
    • allow users to select the parent article of a new article on the web UI, but that is currently doable only with \Include macros
    • allow users to edit the source only for a specific header
  • later on, much later, this will allow WYSIWYG export to plaintext
This also ended up having one unexpected benefit: whenever a new feature is added that deprecates an old feature, by converting the large corpus from github.com/cirosantilli/cirosantilli.github.io to the new feature I can test the new preferred feature very well.
For example, converting \x[blue cat] en masse to the new insane syntax <blue cat> found several bugs with the new insane syntax.
This seemed somewhat easy at first, so I started it as a way of procrastinating more urgent Web features (web scares me, you know), but it ended being insanely hard to implement, because there are many edge cases. Also, most bugs are not acceptable, as they would corrupt your precious source code and potentially output.
But well, it is done!
