🤝 COLLABORATION
Building Data Apps with Streamlit
Streamlit makes it easy to turn Python scripts into interactive web apps. But building production-ready applications requires more than basic widgets.
This hands-on guide covers Streamlit’s architecture, caching, session state, and multipage workflows. You’ll learn to handle secrets, work with APIs and databases, and deploy polished apps to the cloud.
By the end, you’ll build a complete solution that analyzes datasets, trains ML models, and powers an AI chatbot with Google Gemini.

Slim: Reduce Docker Images by 30x Without Dockerfile Changes
Problem
Docker images include the entire OS layer. For a simple Python app, this is unnecessary because it never touches the shells, compilers, and system utilities bundled inside.
This inflates images to hundreds of megabytes, wasting storage and adding time to every deploy.
Solution
Slim automatically analyzes your container at runtime to identify which files are actually used, then builds a minimal image with only essential components.
Slim works alongside Docker, not instead of it:
Step 1: Build your image with
docker buildStep 2: Minify with
slim build your-imageStep 3: Push the
.slimimage to your registryYour Dockerfile and workflow stay the same
LlamaIndex: From Documents to AI Chatbot in 4 Lines
Problem
Building LLM applications from scratch requires managing document loading across different formats, configuring embeddings, setting up vector stores, and orchestrating queries. You end up writing boilerplate code instead of focusing on your application logic.
