"Sample code demonstrating naving around a random graph of data.
The graph very likely will have circular references, which is not a problem.
To see the results, execute the entire file.
Each step in the nav process will be printed out, as well as the initial db.
Subsequent executions will generate a new random db."

I looked into the state of GraalVM and Clojure and wrote some small work-related scripts.

knowledge graph experiment

I like to learn, index and retrieve information a lot. I know a lot of others do as well. We share data but I don't think we share our information and rarely our ontologies (a.k.a. our mental models). If we shared our ontologies, I think we could learn more from each other. With this hope in mind, I'm looking for a tool that provides these features:

  • Shares my ontology publicly
  • Shares my bookmarks publicly
  • Provides easy entry, extension and querying of my ontology
  • Provides easy entry and querying of my bookmarks
  • Shares interesting snapshots of my bookmarks
  • Encourages discovery of information that is new and interesting to others

Since I have not found such a tool, I have built a tool that:

# == Description
# Prints out a tree of classes and their methods for a rails project. Can be run from the
# root directory of a rails project or with a specified rails directory. By default
# this script only looks in the models, controllers and helpers directories for ruby classes but that can be
# configured.
# This was useful back in the day when Rails projects were small and I wanted to a quick overview of
# the project.
