Here is the best setup (I think so :D) for K-series Keychron keyboards on Linux.
Note: many newer Keychron keyboards use QMK as firmware and most tips here do not apply to them. Maybe the ones related to Bluetooth can be useful, but everything related to Apple's keyboard module (hid_apple) on Linux, won't work. As far as I know, all QMK-based boards use the hid_generic module instead. Examples of QMK-based boards are: Q, Q-Pro, V, K-Pro, etc.
Most of these commands have been tested on Ubuntu 20.04 and should also work on most Debian-based distributions. If a command happens not to work for you, take a look in the comment section.
Older Keychron keyboards (those not based on QMK) use the hid_apple driver on Linux, even in the Windows/Android mode, both in Bluetooth and Wired modes.
I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.
So below I made a list of leetcode problems that are as close to grokking problems as possible.
You can download whole courses from an array of tutorial sites with the CLI tool youtube-dl. In the example further down I'm using my Pluralsight account to get videos from a course at their site. Here is a list of all supported sites that you can download from with this tool
The flags you have to supply may vary depending on which site you make a request to.
You can get a free 3 month trial to Pluralsight by signing up for free to Visual Studio Dev Essentials
You will need something from your Stock ROM first. Get them all and Try to modify it using the procedure.
Note: This guide will be helpful for you if you have older mediatek devices (android-5.1 or android-6.0), but up-to-date devices can also work.
Update: This guide had a few typos and derps (Oops..), but I've tried to make it free of those now (Dated November 18, 2020)
Bonus: You can also use this tool by @SebaUbuntu, @yshalsager and @mauronofrio to auto generate the twrp tree. The tool is best if your device runs on android-9.0. The tools is still not 100% compatible to all devices, but I'll still recommend it and give it 8.5/10 in the scale of varsatility.

Caveat
You're not going to get a beautiful EPUB out the other end - if that's what you're looking for, expect to do some manual clean-up work yourself.
Basic order of operations:
- Convert your PDF to an OCR-friendly format
- OCR that shit into plaintext
- Convert that plaintext into your format of choice (in this case, an EPUB)
