Catchall for 25 years :) (on domainfactory - df.eu) each company/service gets their own email prefix, so I can determine spam and also filter unsolicited emails.

Thanks for the praise for APOC-ML, happy that it's useful.
Did you see the two blog posts that Tomaz Bratanic did on the topic?
For the ingestion: https://neo4j.com/developer-blog/global-graphrag-neo4j-langc... For the retrievers: https://neo4j.com/developer-blog/microsoft-graphrag-neo4j/
My general point on GraphRAG is that it extracts and compresses the horizontal topic-clustering across many documents and makes that available for retrieval.
And that by creating the semantic network of entities, you can use patterns in the graph structure to answer questions that rely on information coming together from different documents. Think the detectives board connecting facts with strings from many different sources.
Feel free to ping me for a deeper discussion: michael at neo4j

RenTec was covered in much depth at the Acquired podcast.
Basically algorithms from signal processing applied to huge volumes of historical and current data to determine buy and sell signals. Originally developed for national defense.
Very secretive all external partners were bought out. Only hundred or so people benefited in the billions per person. Including Robert Mercer of Trump campaign financing and Cambridge Analytica fame.
Very interesting but also disheartening episode about smart people only caring about getting richer.

Many advanced RAG patterns are easier with a graphdb and you can pull the relevant context starting with the vector search results.
You can also construct graphs with an llm out of text. See here. https://neo4j.com/labs/genai-ecosystem/llm-graph-builder/

God wrote in Lisp, Bob Kanefsky performed by Julia Ecklar. My favorite song.

For God wrote in Lisp code
When he filled the leaves with green.
The fractal flowers and recursive roots:
The most lovely hack I’ve seen.
And when I ponder snowflakes, never finding two the same,
I know God likes a language with its own four-letter name.

Unbelievable that they completely missed to mention the equivalent in size but failed airship company Cargolifter in Germany.
They operated in the early 2000s and went bankrupt.
They construction dome is as high as the Statue of Liberty and as long as the Eiffel Tower. Now used as indoor tropical resort.

The article is factually incorrect on many fronts. There were only 3 reactors running at last. Nuclear was never profitable, the country shouldered most of its costs (esp for radioactive waste storage)
The renewable energy transition was blocked and delayed by the same Merkel govt. Germany was once leading in wind and PV energy and all those industries were destroyed and almost 100k jobs lost. 60bn subsidies per year go to fossil fuel companies including coal mining and burning. Often under the disguise of job retention. All through industrial lobbying and strong unions in the fossil fuel industries.

I used to do Lego Time Tracking when I was still consulting, as none of the other approaches worked for me (ADHD).
It even made it on LifeHacker back then: https://lifehacker.com/track-your-time-with-lego-bricks-3997...
The article is only on the internet archive these days https://web.archive.org/web/20081206084136/http://jexp.de/bl...
We spend millions turning structured information into PDFs and billions to extract the same data from a printer rendering language
