Tutorial on Linux
Papercompanion for APL Center of Geospace Storms
Pokeballs capture monsters in Containers, and we capture a massive piece of high-performance compute code named Kaiju and Gamera in a Container
This is a demo lab with content from Johns-Hopkins APL
Here, we showcase, how a researcher may share their paper-companions with an interactive part. Remember, the free-tier here is 1 hr (for readers) per day. So, we will keep the tutorial short.
First, let's configure rclone to connect to the Zenodo record using a heredoc. This command creates the necessary directory and writes the configuration file in one step.
mkdir -p ~/.config/rclone/
cat <<EOF > ~/.config/rclone/rclone.conf
[remote]
type = doi
doi = 10.5281/zenodo.8178574
EOF
mkdir -p ~/zenodo_mount
rclone mount remote: ~/zenodo_mount --vfs-cache-mode full &
cat <<EOF > list_zenodo_files.py
import os
import sys
# The path where you mounted the Zenodo remote
mount_path = os.path.expanduser('~/zenodo_mount')
print(f"--- Accessing Zenodo files at: {mount_path} ---")
# Check if the mount point exists and is accessible
if not os.path.isdir(mount_path) or not os.listdir(mount_path):
print(f"Error: Mount point '{mount_path}' is not accessible or is empty.")
print("Please ensure the 'rclone mount' command is running correctly.")
sys.exit(1)
# List all files and directories at the root of the mount
print("Files found in the Zenodo record:")
try:
for item in sorted(os.listdir(mount_path)):
item_path = os.path.join(mount_path, item)
if os.path.isfile(item_path):
size = os.path.getsize(item_path)
print(f"- {item} ({size / 1024:.2f} KB)")
except OSError as e:
print(f"An error occurred while listing files: {e}")
print("-------------------------------------------------")

Now, you should wait until the task below is green to indicate your plot is ready
Head to the other IDE tab and look at the plot
Other things you can do
➡ There is a full tutorial on authoring content
Shared debugging session
Let s assume, you wanted to run the actual code and show to a colleague the output
First, we create a problem: run the docker container
docker run -it adlsregistrysbx.azurecr.io/pokeball/devel:latest /bin/bash -c "cmake -DALLOW_INVALID_COMPILERS=ON /app/. && make gamera -j9 && /app/quickstart/loop2d/prepare_loop2d.py && ./bin/gamera.x loop2d.xml"
You get an code":"UNAUTHORIZED"
Lets assume, you need my help to debug this. So: go to the right top corner
Share a terminal session with another person
You could now share this URL with me and ask me debug the AUTHORIZATION problem.
Expose ports on HTTP/S: example Jupyter
mkdir -p data
cp *.png data
sudo chown -R 1000:100 data
docker run -it --rm \
-p 8888:8888 \
-v /home/laborant/data:/home/jovyan/data \
jupyter/base-notebook \
start-notebook.sh \
--NotebookApp.ip='0.0.0.0' \
--NotebookApp.open_browser=False \
--NotebookApp.password='' \
--NotebookApp.allow_root=True
Now, open the tab (top right again), but first grab the token that jupyter prints into the shell and input the 8888 as port number (no HTTPS).
Click on the generated URL and a new BrowserTab will open, here paste the Token
and Voila !! 🎉
