Ciro's Edict #7 / --format-source by Ciro Santilli 35 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!

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.

Super-resolution microscopy by Ciro Santilli 35 Updated +Created
Super-resolution means resolution beyond the diffraction limit.
First you shine a lot of light which saturates most fluorophores, leaving very few active.
They you can observe fluorophores firing one by one. Their exact position is a bit stochastic and beyond the diffraction limit, but so long as there aren't to many in close proximity, you can wait for it to fire a bunch of times, and the center of the Gaussian is the actual location.
From this we see that super-resolution microscopy is basically a space-time tradeoff: the more time we wait, the better spacial resolution we get. But we can't do it if things are moving too fast in the sample.
Tradeoff with cryoEM: you get to see things moving in live cell. Electron microscopy fully kills cells, so you have no chance of seeing anything that moves ever.
Caveats:
  • initial illumination to saturate most fluorophores I think can still kill cells, things get harder the less light you put in. So it's not like you don't kill things at all necessarily, you just get a chance not to
  • the presence fluorophore disturbs the system slightly, and is not at the same Exact location of the protein of interest

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!
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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
