Objective: Demonstrate three small, extensible programs that illustrate modeling (Python), decentralized simulation (JS), and a minimal command-line kernel (C++).
Duration: 8–12 minutes
Slide 1 — Introduction (30s)
Slide text:
- Tri‑Demo: Algorithm, Governance, Kernel
- Objective: Quick, practical examples covering modeling, simulation, and low‑level interfaces.
Speaker notes:
- “Today I’ll show three short demos that highlight different engineering concepts and how they can be extended.”
Slide 2 — Love Equation (1 min)
Slide text:
- Purpose: Simple implementation of Sternberg’s Triangular Theory of Love.
- Key idea: average of intimacy, commitment, passion → single metric.
- Run: python3 love.py
Speaker notes:
- “This Python script computes a normalized score from three inputs. It’s compact and easy to extend with weighting, validation, or a web form for input.”
Slide 3 — Libertas (2 min)
Slide text:
- Purpose: Minimal decentralized-governance simulation (citizens, proposals, votes).
- Key idea: OO classes, state mutation, easily extended to quorum, weighted votes, or UI.
- Run: node libertas_demo.js
Speaker notes:
- “Libertas shows the core domain model. Add proposal lifecycle, authentication, analytics, or replace in-memory state with a simple database or blockchain simulator.”
Slide 4 — CRA Kernel (2–3 min)
Slide text:
- Purpose: Tiny C++ kernel-like REPL demonstrating boot, command parsing, IO.
- Key idea: control loop, blocking IO; easy to extend with commands, history, help.
- Run: g++ -o cra cra.cpp && ./cra
Speaker notes:
- “This demo is not an OS kernel but demonstrates the small building blocks: boot message, command loop, basic parsing. Good base for teaching or prototyping CLI features.”
Slide 5 — Integration & Next Steps (1–2 min)
Slide text:
- Integration options: Dockerize each demo + simple web UI to trigger runs and stream stdout; or run locally in terminal tabs.
- Next steps picked: slide deck, Dockerfiles + web UI scaffold, 8–12 min recorded demo script.
Speaker notes:
- “We can deliver a polished demo in 1–2 days: Dockerfiles for each, a small Node UI to launch demos and show output, plus the recorded walkthrough.”
Slide 6 — Ask & Timeline (30s)
Slide text:
- Ask: Approval to produce deliverables in chosen format (live demo, recorded video, or slide deck + artifacts).
- ETA: 1–2 days for full integration (Docker + UI + script)
Speaker notes:
- “If this looks good, I’ll produce the deliverables and can adapt the recorded demo to your preferred narration style.”

3) Recorded demo narration script with Neutral/Professional voiceover simulation
- File name: narration.txt
Format: timestamp — narration. Use the “Simulated voiceover” blocks as ready-to-read voice text.
narration.txt
```
00:00 – 00:15 — Opening
Simulated voiceover (Neutral/Professional):
"Hello. In this demo I will present three concise programs: the Love Equation in Python, Libertas in JavaScript, and the CRA kernel in C++. The total runtime is approximately ten minutes."
00:15 – 01:00 — Setup note
Simulated voiceover:
"I am using Docker to run each demo for consistency. The build step is optional to display live; I have prepared images to keep the demo focused on behavior rather than build time."
01:00 – 02:15 — Love Equation demo (run)
Command to run (on-screen): docker run --rm tri_demo_love
Expected output: Love Score: 8.0
Simulated voiceover:
"First, the Love Equation. This small Python function computes a single metric by averaging intimacy, commitment, and passion. Here we pass sample values and obtain a combined score. It demonstrates a compact numerical model and can be extended with weighting or input validation."
02:15 – 04:15 — Libertas demo (run)
Command to run (on-screen): docker run --rm tri_demo_libertas
Expected output (approx):
Alice voted for proposal 0 ('Free Pizza')
Proposals: [{ text: 'Free Pizza', votes: 1 }]
Citizens: [{ name: 'Alice', votes: 1 }, { name: 'Bob', votes: 0 }]
Simulated voiceover:
"Next, Libertas. This JavaScript demo models citizens, proposals, and voting. The example shows adding two citizens, creating a proposal, and casting a vote. It highlights object‑oriented design and state mutation. Possible extensions include quorum enforcement, vote weights, and persistent storage."
04:15 – 07:30 — CRA Kernel demo (interactive)
Command to run (on-screen): docker run --rm -it tri_demo_cra
Expected output:
CRA Kernel booted successfully!
cra_kernel>
Interactive steps (type at prompt):
- help → Expected: Unknown command: help
- foo → Expected: Unknown command: foo
- exit → kernel exits
Simulated voiceover:
"Finally, the CRA kernel. This minimal C++ program prints a boot message and enters a command loop. It demonstrates prompt handling and simple parsing. In this demo I will issue a few example commands to show the behavior. The kernel responds with unknown-command messages; adding a help command and a command registry would be the logical next steps."
07:30 – 09:00 — Integration & extension ideas
Simulated voiceover:
"Integration options include exposing non‑interactive demo outputs through a small web UI, or running the CRA kernel interactively in a terminal. Extension priorities: add input forms and weighting to the Love Equation, proposal lifecycle and analytics to Libertas, and command history and help to the CRA kernel."
09:00 – 10:00 — Wrap-up & ask
Simulated voiceover:
"That concludes the demonstration. I can produce a recorded video file or deliver the artifacts—Dockerfiles, a UI scaffold, and a slide deck—based on your preference. Please indicate whether you prefer a live demo, a recorded walkthrough, or both."
```
Simulated voiceover guidance:
- Pace: moderate, approx. 120–150 words per minute.
- Tone: neutral, professional, clear enunciation.
- Micro-pauses: 0.5–1.0s between sentences; 1.5–2.0s between demo sections.
- Pronunciation notes: spell out acronyms if helpful (C R A).
Build instructions (how to produce PDF and ZIP locally)
- Slide deck PDF:
1. Paste slides.md (or the slide text above) into your favorite slide tool (PowerPoint, Google Slides, or a Markdown-to-PDF tool).
2. Add slides per the headings; paste speaker notes into the Notes area for each slide.
3. Export as PDF.
- Repository ZIP:
1. Create folder tri-demo and subfolders as listed.
2. Save each file with exact filenames and contents shown above.
3. From the parent directory run:
zip -r tri-demo.zip tri-demo
4. The zip file tri-demo.zip contains the full repository.
- Recorded narration:
1. Use narration.txt as the voiceover script.
2. For neutral/professional delivery, record at ~130 wpm with the pacing guidance above.
3. Optionally merge with screen recording of terminal/UI demo.
