How to write a Math or Data Science eBook?

When studying, I like to take notes, usually, I do it on my Blog, but often I use Jupyter notebooks which I commit to GitHub. If I am writing a paper I use Google Docs. Having my writing in 3 different places is not optimal. 

On top of that, using math formulas complicates things as it is not supported everywhere.

Example of a formula written using LaTeX:

$$ LogLoss = - \frac{1}{n} \sum_{i=1}^{n}
( y_i \cdot log(\hat{y_i}) + ( 1 - y_i ) \cdot \log(1 - \hat{y_i}) ) $$

So, how should I write a Math, or a Data Science, eBook?

First, publishing papers as PDF is most common, I read tons of them, but they are hard to digest unless you print them, or view them on a big screen. I do not want to sit in front of the computer any longer than I already do.  I like using Kindle reader, so an eBook format is much more user-friendly. I can set font sizes, and spacing, take notes, etc. The PDFs on Kindle are a really bad experience. Also, I would like to distribute my papers over the Amazon Kindle store (for free or not). Not everyone has a university or a work subscription to access papers on ieee.org, sciencedirect.com, proquest.com, etc.

Below, I will investigate different approaches and hopefully, come to a good conclusion.

How to send documents to Kindle:

• Every Kindle account has an associated (secret) email, you can attach a file to it and it will show in your Kindle.
• Make sure the file name is human-readable!
• HTML (export from Jupyter Lab) sent to Kindle:
• PRO:
• it is readable, good for text-only pages
• CON:
• LaTeX is not converted to math formulas
• Images are missing
• PDF (of the same HTML) sent to Kindle:
• PRO:
• images show up
• LaTeX formulas show up
• good enough to publish a "paper"
• CON:
• still the problem with PDF in general -- no font size adjustment
• ePUB (of the same HTML) sent to Kindle:
• conversion is done with convertio.co
• PRO
• font adjustable
• plots included
• CONS:
• missing images
• LaTeX not converted to math formulas 
• conversion with  calibre-ebook.com
• 
  

Is Blogger (Blogspot) good for writing papers and articles?

Pro:

• searchable 
• easy to manage and edit
• use of tags (labels) for finding related articles
• support for LaTeX math notation

Cons: 

• No good ways to "clean" export to ePub, PDF, or Markdown
• I could write embedded JavaScript in Blogger that creates "print" version of article text only

Using Jupyter Notebook

Pro:

• inline and current code (Julia, Python)
• incline and current plots 
• export to HTML, PDF, Markdown with pandoc.org/

Cons

• no spellcheck while writing (Grammarly)

• conda install -c conda-forge jupyterlab-spellchecker

• GitHub Diff is garbage

Using Google Docs

Pros:

• Available on all devices, online and offline
