MySQL practice problems using the Employees Sample Database along with my solutions. See here for database installation details.

Problem 1

Find the number of Male (M) and Female (F) employees in the database and order the counts in descending order.

SELECT gender, COUNT(*) AS total_count
FROM employees 
GROUP BY gender

Fedora 35 NVIDIA/CUDA Installation for TensorFlow

These are the steps I took for the installation of the NVIDIA drivers and CUDA toolkit for use with TensorFlow on Fedora 35. I have documented them since I had a lot of difficulty getting it to work and couldn't boot to a graphical desktop a few times. These steps worked for me, hopefully they do for others.

Assumptions

I am running on a 64 bit system and used KDE Plasma with X11 so these instructions may differ for people using GNOME, Wayland and any other combinations.

Pre-requisites

• If you have installed any NVIDIA drivers other than the akmod-nvidia drivers from the @rpmfusion-nonfree repo, remove them completely.
• Remove any other NVIDIA/CUDA installations. Find them with sudo dnf list installed | egrep '(nvidia|cuda)'
• If the nvidia-driver module is enabled, disable it - sudo dnf module disable nvidia-driver - this caused me issues when trying to install the akmod drivers
