- fix course number 223015c → 223015b in termin 1 - adjust language: "fuck" → "heck" in example - add black backgrounds for image-only slides - add bg fit to fullscreen images - update digital-landscape.png - add frontmatter to termin 2-4 slides
- frontpage: black bg, title, 223015b, git link - email: mail@librete.ch (both files) - remove forum references (no forum for 60 students) - remove screenshot requirements (just experiment) - simplify fleißaufgaben (no submission, discuss next week) - deepen speaker notes for bits/bytes beginners: - bit (shannon, why binary) - byte (why 8 bits, ibm history) - 256 states (everyday examples) - hexadecimal (why hex, conversion practice) - magic numbers (security aspect) - mp3 (4 steps simplified)
