# Humanify Slide Command
|
||||
|
||||
Transformiere die angegebene Slide(s) in meinen persönlichen Lehr- und Erzählstil.
|
||||
|
||||
**Argument:** $ARGUMENTS (Slide-Nummer, Titel, oder Range wie "15-20")
|
||||
|
||||

|
||||
|
||||
## Mein pädagogischer Stil (extrahiert aus Termin 1)
|
||||
|
||||
### 1. Konversationelle Speaker Notes auf Deutsch
|
||||
- Direkte Zitate in Anführungszeichen: `"Ich schaue in viele fragende Gesichte..."`
|
||||
- Natürliche, gesprochene Sprache - kein Vorlesungsdeutsch
|
||||
- Persönliche Ansprache: "ihr", "euch", "wir"
|
||||
|
||||
### 2. Storytelling & Spannungsbogen
|
||||
- Cliffhanger: `"am Ende der heutigen Veranstaltung werdet ihr mir genau sagen können..."`
|
||||
- Übergänge zwischen Konzepten als Geschichte erzählen
|
||||
- Neugier wecken bevor die Antwort kommt
|
||||
|
||||
### 3. Rhetorische Fragen & Interaktion
|
||||
- `Frage: "Weiß jemand wieviele Zustände wir mit 8 Bit beschreiben können?"`
|
||||
- `Fangfrage: "Wie hoch ist die Sample Rate von Vinyls?"` → Überraschende Antwort
|
||||
- Einladungen: `"Wie würdet ihr vorgehen?"`
|
||||
|
||||
### 4. Literarische & kulturelle Referenzen
|
||||
- `»256 Shades of Gray«` (mit deutschen Guillemets »...«)
|
||||
- Metaphern: `"ganz literarisch"`, `"stellt euch vor ihr seid ArchäologInnen"`
|
||||
- Popkulturelle Anknüpfungspunkte
|
||||
|
||||
### 5. Rätsel & Denkaufgaben
|
||||
- Seerose-Rätsel für exponentielles Wachstum
|
||||
- Aktivierung statt passives Zuhören
|
||||
|
||||
### 6. Etymologie & Historie
|
||||
- Wortherkunft: `"von griech. hexa „sechs" und lat. decem „zehn""`
|
||||
- Historische Anekdoten: `"Es gab durchaus einen »Machtkampf«..."`
|
||||
- Personen hinter den Konzepten
|
||||
|
||||
### 7. Progressive Enthüllung
|
||||
- Konzepte über mehrere Slides aufbauen (Das Byte: 3 Slides)
|
||||
- Erst Frage, dann Antwort auf nächster Slide
|
||||
- Spannung halten
|
||||
|
||||
### 8. Struktur der Speaker Notes
|
||||
```markdown
|
||||
<!--
|
||||
"Gesprochener Text in Anführungszeichen"
|
||||
|
||||
Fakten und Hintergrundinfos als Stichpunkte:
|
||||
- Punkt 1
|
||||
- Punkt 2
|
||||
|
||||
Frage: "Interaktive Frage an Studierende?"
|
||||
|
||||
Überleitung: "Und damit kommen wir zu..."
|
||||
-->
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Aufgabe
|
||||
|
||||
1. Lies die angegebene(n) Slide(s) aus den Dateien in `slides/`
|
||||
2. Analysiere den aktuellen Inhalt und die Speaker Notes
|
||||
3. Transformiere die Speaker Notes in meinen Stil:
|
||||
- Füge gesprochene Zitate hinzu
|
||||
- Baue rhetorische Fragen ein
|
||||
- Ergänze Übergänge und Storytelling-Elemente
|
||||
- Füge Etymologie oder historischen Kontext hinzu wo passend
|
||||
- Nutze deutsche Guillemets »...« für Titel/Zitate
|
||||
4. Behalte die Slide-Inhalte (Bullet Points, Code, Tabellen) weitgehend bei
|
||||
5. Zeige mir die vorgeschlagenen Änderungen bevor du sie anwendest
|
||||
|
||||
**WICHTIG:** Nicht übertreiben! Authentisch bleiben, nicht jede Slide braucht alles.

## Agent Restrictions
|
||||
- Agent NEVER runs commands on its own except changing files INSIDE THIS FOLDER, never any other then this
|
||||
- Agent NEVER runs build commands or any automated processes without explicit user request, as the user is working in dev mode

- Agent NEVER runs deploy commands (make deploy, scp, etc.) without explicit user permission - always ask first

|
||||
|
||||
**Hinweis:** TXT, HTML, CSS haben **keine** Magic Number!
|
||||
**Wichtig:** ASCII = nur 0-127! Werte darüber (z.B. `89` = 137) sind **nicht druckbar** (non-printable). *Hex-Editoren zeigen dafür `.` oder `ÿ` als Platzhalter.*
|
||||
|
||||
<!--
|
||||
Magic Number = Signatur/Fingerabdruck am Dateianfang
|
||||
Wozu? Betriebssystem erkennt Dateityp unabhängig von Dateiendung
|
||||
"Warum findet ihr 89 nicht in der ASCII-Tabelle?"
|
||||
|
||||
KERNKONZEPT:
|
||||
- 1 Byte = 256 Werte (0-255)
|
||||
- ASCII deckt nur 0-127 ab (die "druckbaren" Zeichen)
|
||||
- 128-255 = Binärdaten, Steuerzeichen, erweiterte Zeichen
|
||||
|
||||
WARUM nutzt PNG absichtlich 89 (= 137 dezimal)?
|
||||
1. Markiert die Datei eindeutig als BINÄR, nicht Text
|
||||
2. Erkennt kaputte Übertragungen (alte Systeme schnitten Bit 7 ab)
|
||||
3. Verhindert versehentliches Öffnen als Textdatei
|
||||
|
||||
Geschichte: "PK" bei ZIP = Phil Katz (Erfinder von PKZip, 1989)
|
||||
Fun Fact: DOCX, XLSX, PPTX, ODT = alles ZIP-Archive mit XML-Inhalt!
|
||||
→ Einfach .zip anhängen und entpacken!
|
||||
|
||||
Dateien OHNE Magic Number: TXT, HTML, CSS, JSON, XML
|
||||
→ Diese sind reiner Text, kein binäres Format
|
||||
→ Werden anhand Inhalt/Endung erkannt
|
||||
→ Reiner Text, kein binäres Format
|
||||
|
||||
Sicherheits-Aspekt:
|
||||
virus.exe → bild.jpg umbenennen täuscht nur Menschen
|
||||
Windows vertraut der Endung, aber Tools wie "file" (Linux) lesen Magic Number
|

→ Nie Dateien von Fremden öffnen, nur weil sie harmlos aussehen!
