Netherlands. April 2026.
New app function gives cyclists automatic green light priority at smart traffic signals nationwide.
How: anonymous signal sent to iVRIs intelligent traffic control installations already used for emergency vehicles, buses and freight trucks. Now extended to cyclists.
Provinces: Limburg, Noord-Brabant, Overijssel, Utrecht, Zuid-Holland + 3 more.
Thousands of signals. Number growing significantly.

Netherlands. Dutch universities and government form joint committee with SURF to reduce reliance on Microsoft, Google and Amazon.
Concerns: academic freedom and data protection.
The pattern is clear:
→ France orders all ministries to migrate from Windows to Linux
→ OpenAI pauses Stargate UK over energy and regulatory uncertainty
→ Dutch universities push Big Tech out of academia
Europe is rewriting the rules of digital dependency.

Across Europe, some countries are reducing fuel taxes to ease pressure on consumers and businesses.
Germany is taking a different approach, maintaining high fuel taxation — including CO₂ pricing — to accelerate the shift toward electric mobility.
A clear policy trade-off: immediate cost relief vs structural transition.

RAG system. Day 2: Setup.
Three tools. One goal.
pip install langchain anthropic chromadb
→ LangChain: orchestrates the pipeline
→ Claude API: generates answers from retrieved context
→ ChromaDB: stores and retrieves vector embeddings locally
Next step: load the Oscars dataset from Kaggle — 95 years of winners, nominations, box office. Turn it into chunks. Create embeddings. Store in ChromaDB.
Day 3 tomorrow: indexing the data.
GitHub repo published on Day 5.
#RAG #LangChain #Python #AI #LLM

Building a RAG system in 5 days. Day 1: the concept.
RAG = Retrieval-Augmented Generation.
Instead of relying only on what your LLM was trained on, you give it access to your own documents — in real time.
How it works:
→ User asks a question
→ System retrieves relevant chunks from your data
→ LLM generates an answer grounded in those chunks
This week: building it with LangChain + Claude API using 95 years of Oscars data.

Turkey just approved 33GW of battery storage.
Germany sits around 12–13GW.
This isn’t about technology.

The energy transition won’t be led by who innovates first —
but by who deploys fastest.
