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.

Make Fn + F-keys work (NOT FOR QMK-BASED BOARDS)

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.

SETTING

Step-1

Create provider_paths.xml in res/xml folder and write below code in it.

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">

For a simple way to use environment variables in your react-create-app project, follow these steps:

Create a new file named .env in the root of your project.
In your new .env file, add a new key=value pair. For security reasons, you must prepend your key with REACT_APP, for example REACT_APP_API_KEY=abcdefg123456789
Restart your server development server. In order for React to find and register your newly created environment variable you must restart your server. Do this every time you add or change a variable.
Your new variables will now be available throughout your React app via the global process.env object. In our case, we could get our API key using process.env.REACT_APP_API_KEY.

Additinal notes

Since we commonly store secrets in .env you probably want to add it to .gitignore.
You don't need to install the dotenv package or anything else for this to work.

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft
