Rubber Duck Thursday | Come code and hang out with us!

Rubber Duck Thursdays - Summary

Key Concepts:

• Fancy Gist: A UI enhancement for GitHub Gists, adding features like slash commands, markdown previews, and downloadable formats (Markdown, HTML, PDF).
• AI-Powered Video Editing: A project aiming to automate video editing using LLMs for transcription and cut suggestion, combined with B-roll integration.
• Copilot CLI: GitHub Copilot’s command-line interface, used for planning and implementing software projects through natural language prompts.
• Agentic AI: Utilizing AI agents (like those powered by Copilot) to autonomously perform tasks, including code generation, deployment, and infrastructure setup.
• Zo.computer: A platform allowing users to self-host open-source applications without managing infrastructure.
• GitHub Copilot SDK: A toolkit for building custom applications that integrate with GitHub Copilot and its features.

1. Fancy Gist – Enhanced GitHub Gist Experience

Cadia introduced “Fancy Gist,” an open-source project designed to improve the user experience of GitHub Gists. Currently, Gists are basic text/markdown files. Fancy Gist adds functionality through slash commands. Examples include /table to generate a markdown table, commands for dummy text, and markdown alerts that render visually when previewed. The project allows opening existing Gists via fancyjist.com instead of github.com. Users can edit, save, and download Gists in Markdown, HTML, or PDF formats. Future plans include theming via URL query parameters (e.g., ?theme=darkmode) and support for animated GIFs and emojis. The project is available on GitHub with “good first issues” for contributors.

2. AI-Powered Video Editing – Automating the Post-Production Workflow

Cadia is developing a tool to automate video editing, specifically for talking-head videos. The process involves:

• Transcription: Converting video to text using speech-to-text technology.
• LLM-Based Editing: Utilizing a Large Language Model (LLM) to analyze the transcript and identify segments for removal (filler words, pauses, retakes, repetitions).
• B-Roll Integration: Searching a library of B-roll footage and automatically inserting relevant clips.

The current challenge lies in teaching the LLM to accurately identify and remove unwanted segments without losing core talking points. The project leverages FFmpeg for video editing capabilities. The initial implementation uses Claude for transcript analysis and generates an “edit decision list.” The system considers video orientation (vertical vs. horizontal) and allows for varying levels of editing aggressiveness.

3. GitHub Copilot CLI & Agentic AI – Streamlining Development

The discussion highlighted the power of the GitHub Copilot CLI for rapid prototyping and development. Cadia demonstrated using Copilot CLI in “plan mode” to outline the implementation of a feature for Fancy Gist (dynamic file naming based on the first line of the Gist). The CLI generates a plan, which can then be executed to write the code. Copilot CLI was also used to quickly build a functional Voice Notes clone in approximately 20 minutes, showcasing its ability to generate a complete application from a natural language prompt. This exemplifies agentic AI, where the AI autonomously handles tasks like code generation and infrastructure setup.

4. Zo.computer – Simplified Open-Source Hosting

Zo.computer was presented as a platform that simplifies the deployment of open-source applications. It allows users to host applications like Postis (a self-hosted alternative to Buffer for social media scheduling) and N8N (an open-source workflow automation tool) without the complexities of self-hosting. Zo handles infrastructure management and authentication, providing a convenient way to experiment with open-source tools. Andrea, a coworker, was highlighted as a Zo user with a personal website hosted on the platform.

5. GitHub Copilot SDK – Building Custom AI-Powered Tools

Cadia showcased a custom application built using the GitHub Copilot SDK, called “Mona AI Hub.” This application provides a UI for managing Copilot agents, selecting models, and running tasks. The SDK handles authentication and integration with GitHub, allowing developers to build tailored AI-powered tools. The application logs all agent sessions to the user’s GitHub account for auditing and review.

6. Technical Details & Tools Mentioned:

• GitHub Copilot: AI pair programmer.
• GitHub Copilot CLI: Command-line interface for Copilot.
• FastAPI: Python web framework used in the Fancy Gist backend.
• Injust: (Likely a typo for InfluxDB) Time-series database.
• Deepgram: Speech-to-text API used for video transcription.
• Electron: Framework for building desktop applications (used for Mona AI Hub).
• Next.js, React, TypeScript: Technologies used in the Voice Notes clone.
• FFmpeg: Command-line tool for video editing.
• Claude: LLM used for transcript analysis in the video editing project.
• Postis: Open-source social media scheduling tool.
• N8N: Open-source workflow automation tool.
• Voice Notes: A voice recording and transcription app.

7. Logical Connections & Flow:

The conversation flowed from a discussion of Cadia’s personal projects (Fancy Gist, AI video editing) to broader themes of AI-assisted development (Copilot CLI, SDK, agentic AI) and simplified open-source hosting (Zo.computer). The demonstration of the Voice Notes clone served as a powerful example of the speed and efficiency enabled by these tools. The discussion consistently emphasized the potential for AI to automate repetitive tasks and empower developers to focus on higher-level creative work.

8. Data & Statistics:

• The creator industry is estimated to be a nearly $500 billion industry.
• Buffer social media scheduling costs approximately $18/month for three accounts, increasing with more accounts.

Conclusion:

The Rubber Duck Thursday session highlighted the rapidly evolving landscape of AI-assisted development. Tools like GitHub Copilot, Zo.computer, and the Copilot SDK are empowering developers to build and deploy applications faster and more efficiently. The emphasis on agentic AI and simplified infrastructure management suggests a future where developers can focus on ideation and problem-solving, leaving the more mundane tasks to AI agents. The showcased projects, particularly Fancy Gist and the AI video editor, demonstrate the practical applications of these technologies and the potential for innovation in various domains.
