## Notes

Course site for the laser cutting intro course ("Introkursus til lille laser"),
in Danish. Serves the course materials (slides, plancher, worked examples) for
download and takes participant file uploads during the course.

Behind Traefik basicAuth — the credentials are handed out in class. Uploads are
restricted to laser-relevant formats (SVG, DXF, PDF, common raster, archives),
capped at 20 MB, and stored as `<participant>_<timestamp>_<filename>` under
`/srv/laser_course/uploads`.

Deployed from the `baobab.laser-course` role in AnsibleBaobabV4 (the app source
and the course materials both live in that role):

```bash
ansible-playbook play_containers.yml --limit makerfloss -t laser-course
```

Two things worth knowing before a course:

- **Uploads are not backed up.** `backup_enabled` is false on this VPS, and
  `laser_course_clean_uploads_on_deploy` is set to false here so that an
  unrelated deploy does not delete them. Collect anything worth keeping and
  clear the directory by hand between courses.
- The site moved here from `laser.baobab.band` on the home estate in August
  2026; `laser.makerfloss.eu` is the canonical address.
