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.

You first need to undestand the concept of frontend tests.

You should not test the implementation but the behavior

You test like the end user

For instance, imagine a login screen with email and password inputs and a submit button

The test should input the email and the password, then click in the submit button.

Looking for the First Job

Versão em Português

This is a very common state for people in college, people before/after a bootcamp, or people from another area.

The first job will be the hardest one to get, but it will get easier over time.

The interview will be harder than the job itself
