knktc's Notes

Several ways to execute a standalone script inside a Django project environment, including shell redirection and a custom management command.

A small Chrome extension that injects code into YouTube Music to help avoid accidentally closing the app window.

Configure auditd to stop rotating by size and use a daily cron job to rotate, rename, compress, and prune audit logs by time.

Query RabbitMQ queue length through Celery and Kombu, and purge a queue when needed.

Avoid creating new migrations every time a choices list changes by generating model choices from a helper function.

If pgpool2 closes idle client connections before Django notices, manually closing Django DB connections can avoid OperationalError in long-running tasks.

Use broker_transport_options to limit producer retry behavior so apply_async and delay do not hang indefinitely when the broker is unavailable.

A personal step-by-step note on lowering pressure on a Bosch wall-mounted gas water heater after the pressure gauge climbed too high.

If a remote Python 3 script fails with UnicodeDecodeError over SSH, mismatched locale environment variables between client and server may be the cause.

Build a lightweight asynchronous task queue with uWSGI's built-in spooler instead of introducing Celery, RabbitMQ, or Redis.
