ERR_NVGPUCTRPERM: Permission issue with Performance Counters

Solutions for this issue

NVIDIA has a page that addresses the issue. Unfortunately, the instructions didn't solve the problem for me. However, I found a solution from rameshgunjal in the NVIDIA forums.

Option 1: Running the program as admin

You might have noticed that sudo nv-nsight-cu results in an error. Instead, you have to provide the path: sudo /usr/local/cuda/bin/nv-nsight-cu. The same applies for other applications as well: sudo /usr/local/cuda/bin/nsight-sys.

Methods of Signing Git Commits on MacOS

Last updated March 13, 2024

This Gist explains how to sign commits using gpg in a step-by-step fashion. Previously, krypt.co was heavily mentioned, but I've only recently learned they were acquired by Akamai and no longer update their previous free products. Those mentions have been removed.

Additionally, 1Password now supports signing Git commits with SSH keys and makes it pretty easy-plus you can easily configure Git Tower to use it for both signing and ssh.

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing your commits with GPG.
