Enhancements in Graph Model: Dynamic Entities & Full-Text Search - savas parastatidis As I continued work on BrainExpanded and its MCP service, I came to realize that I needed support for dynamic entities and full text search in the Graph Model API. I just published a new release of th...

A new alpha release of the Graph Model package is out.

GraphModel: A .NET Abstraction for Graphs - savas parastatidis Just over a month ago, I published “Playing with graphs and Neo4j“. Back then, it was just a toy implementation, an experiment, to help me with what I have been doing for my startup. Well, that little experiment has grown into something much more substantial. As I started building on top of my Neo4j Graph […]

I built the Graph Model abstraction and implementation over Neo4j to support my startup-related explorations. I am making it available as open source with the hope that the community will help me evolve it.

If got back $0.01 for every time Github Copilot said "Ah, now I can see the real issue!" or "Perfect! Now I can see the issue clearly" but then recommends a fix that doesn't actually work, Microsoft would be owing me money now.

I'm going to support any necessary changes to the US constitution that can make it possible for Jacinda Ardern to run for president here.

Argh! I kept approving Copilot’s suggested commands so I didn’t notice. Here’s Claude Sonnet 4’s response after 30mins of collaborative work on a major refactoring

"You're absolutely right! The git reset --hard HEAD command I ran reverted all the changes we made during this session.”

Playing with graphs and neo4j - savas parastatidis After my initial implementation of some BrainExpanded-related ideas on top of dgraph using its GraphQL interface, I realized that the GraphQL data model was a bit restrictive for what I needed. It’s a...

We were having a conversation about some code it recommended when I pointed out an obvious mistake.

BrainExpanded - Web app and Data Sources - savas parastatidis As I wrote in previous posts, the manual recording of memories for BrainExpanded is just the beginning. Once the basic infrastructure is in place, devices (e.g. phones, laptops, wearables) and applica...

Ha ha. The latest ChatGPT update considers all past interactions when generating a response. To showcase the feature, it offered to describe me based on all our past chats. Not bad! 😀 The conversation continued all the way to focusing on BrainExpanded material for investors, press, end users. 😀

yup. I know about this library. Not what I needed.

No decision made yet. But I have this IM exchange with someone I trust who advised me to keep it simple for now. So that’s what I did… I kept it simple. I couldn’t find a GraphQL interface to neo4j except the JS library that maps GraphQL to Cypher.

BrainExpanded - Login State Caching Issue in iOS Share Extension - savas parastatidis As part of the BrainExpanded project, I’m building an iOS app that lets users easily add links, text, and images to the “brain’s memory.” Once in the memory, various agents process the content to make it more accessible and useful (see previous posts for a description). The app’s XCode project has two targets: the main […]

From enhancing the capabilities of our smartphones to revolutionizing industries such as healthcare, finance, and transportation, AI technologies hold immense potential. But is AI a hero or a villain? This question sparks endless debates as we […]

BrainExpanded - Copilot - savas parastatidis Happy New Year everyone! I was planning for my next BrainExpanded post to be a report of the entire end-to-end experience and backend working. However, a coding-related moment with Microsoft’s Github Copilot led me to this note. Previous posts Over the holidays, I made good progress on BrainExpanded. It’s been so much fun! The initial […]

Progress on BrainExpanded and how Copilot is helping.

BrainExpanded – Introduction:

People you meet in person aren't the target audience. Digital twins is how you scale, if that is what you want to do 😀

How about I build one for you that answers questions about dancing and traveling 😀

Digital twin follow up - savas parastatidis Back in February, I shared the results of some initial experimentation with a digital twin. It was my way of learning tools such as langchain, ollama, vector stores for retrieval, etc. Then work got in the way and I never followed up. Until now. While still thinking about the digital twin, I started thinking about […]

Follow up to my "digital twin" experiment with LLMs. This was fun! I learned something.
