When trying to output directory names on a Mac, there are instances where diacritic marks (like dakuten) appear as separate characters. This issue arises due to differences between Unicode normalization forms NFC and NFD. It can be fixed using unicodedata.normalize.

The migration for the `oauth2_provider` app included in Django's `django-oauth-toolkit` failed at migration 0004. The issue was resolved by manually removing the foreign key, changing the integer field to a bigint, and then reapplying the foreign key.

When attempting to create a Python 3.10 environment using `pipenv install` and encountering the error "RuntimeError: location not created nor specified," it may be due to using the pipenv installed in a Python 3.9 environment. To resolve this issue, you should install pipenv in the Python 3.10 environment.

Until now, I often created Django images using Alpine Linux and uWSGI, but there is a performance issue when running Python on Alpine Linux. This is a note on changing the Docker image configuration from Alpine to Debian and the HTTP server from uWSGI to Daphne + WhiteNoise.

This article provides key points to check the configuration in cases where you are using the Nginx Ingress Controller with Kubernetes and Uwsgi for the application server within the Pod, to prevent slow response services from timing out. If these configurations are not extended, it could result in 502 or 504 errors.

When using version locking systems like Pipenv to set up a Python environment with an Alpine Linux Docker image, installations often encounter difficulties. If installing `cryptography` via Rust is unsuccessful (or too slow and thus undesirable), it is more effective to install `cryptography` via `apk` rather than through Pipenv.

Extracting email addresses that have hard bounced from Postfix logs using a one-liner. Email sending must be stopped for addresses that have hard bounced.

I attempted to retrieve the source global IP address from HTTP requests through Kubernetes Ingress, but I ended up obtaining the IP address of Kubernetes' local network, which did not work as intended. After switching Kubernetes to MicroK8s and using its built-in Ingress controller, I was able to successfully retrieve the global remote IP address. This is a note on that experience.

When using MicroK8s on a server, a separate image repository for ctr is created apart from the server's Docker image repository. Since MicroK8s uses this ctr, Docker-loaded images cannot be used directly. It is necessary to import the images using `microk8s ctr image import`.
