Docker/Podman tips

Docker unlimited resources docker run --gpus all --ipc=host --ulimit memlock=-1 --ulimit stack=67108864 -it --rm --privileged --detach-keys "ctrl-a,a" -v $(pwd):/workspace <image-name> Map detach-keys to something else The default detach shortcut is ctrl-p, ctrl-q conflicting the previous command ctrl-p. Adding the option --detach-keys "ctrl-a,a" maps it to something else. Port forwarding -p 9999:9999 Use Host DNS --dns-opt=/etc/resolv.conf Podman Container Device Interface (CDI) From NVIDIA ref sudo dnf clean expire-cache \ && sudo dnf install -y nvidia-container-toolkit-base sudo nvidia-ctk cdi generate --output=/etc/cdi/nvidia.yaml grep " name:" /etc/cdi/nvidia.yaml It should show the GPU device ids (this example is for two gpus):

Exercism Cli Shortcut

A Exercism CLI shortcut Exercism is a good place to learn and practice coding. It features a variety of programming languages (tracks) ranging from popular ones like python and C++, newer ones like Rust, Go and Clojure, to exquisite ones like vimscript. Each track consists of a series exercises that one need to challenge them in sequence. Some tracks feature real person mentors, which provides feedback and (dis)approves your solution! Yep, the next exercise would be unlocked only if your solution had been approved by the mentor, which may take some iterations and discussions. Most importantly, Exercism comes with a command line interface (CLI) that is very convenient to use.
