help works fine:
uv run test-pydantic.py -h
pydantic_settings.VERSION='2.13.1'
usage: test-pydantic.py [-h] [--config CONFIG] [--db_url HttpUrl] [--api_key str] [--port int] [--env {dev,stg,prod}] [--created_at AwareDatetime] [--debug bool] [--log_dir Path]
options:
-h, --help show this help message and exit
--config CONFIG
podman run -v /data/devspace/dummy/test/A:/mnt/A:Z -v /data/devspace/dummy/test/B:/mnt/B:Z --rm -it ubuntu:latest /bin/bash
following works fine
root@68ec02c9b450:/mnt# cp --reflink=always A/test10M.bin A/reflinked.bin
[dummy@host test]$ xfs_io -r -c 'fiemap' A/reflinked.bin
reflinks can be used as CoW mechanism for XFS since 4.17.0-2.el8
This feature enables two or more files to share a common set of data blocks. When either of the files sharing common blocks changes, XFS breaks the link to common blocks and creates a new file.
so with cp --reflink we can create CoW blocks already. This is similar to btrfs CoW.
We can simply do following to mimic the snapshot:
find /root -mindepth 1 -maxdepth 1 -not -name "backup" -exec cp -r --reflink {} /root/backup/$(date)/ ;

there is almost NOT legacy iptables command (iptables) on modern OS (RHEL8, ubuntu22, etc) there can still be some lagecy ip_tables module loaded:
lsb_release -d; lsmod | grep tables; iptables -V

The styler gives us a easy way to format the dataframe and maintain the format across different kind of output: html, excel, etc.
However, one of my friends has spot a problem of it, the styler.to_excel() output some how supressed some advanced formating of XlsxWriter. Here is an example:
import pandas as pd
data = pd.DataFrame({"A":list(range(10,12)), "B":["abcdefgafafadf", "afbafafafafadfadfadf"]})
with pd.ExcelWriter("/tmp/test.xlsx") as writer:
data.style.apply(lambda x: ['background-color: red']*2 if x['A']==11 else [None]*2, axis=1).to_excel(writer, index=False)
writer.sheets["Sheet1"].write(3, 1, "Some long text to wrap in a cell")
