This repository hosts notes/notebooks and one off explorations, so I can look them up easily.

The posts are in reverse chronological order by the date they were added, though most date back to further before.

Index

Nicer SQL syntax using FunSQL

  • date: 2022-06-27
  • topic: Jupyter notebook that addresses some of the SQL syntax quirks mentioned in the against-sql post by Jamie Brandon. Uses the FunSQL python library.
  • tiny-notes: Using a DSL hosted in the language allows for richer abstractions. I really need to clean up the FunSQL library code though.

VMSP algorithm

  • date: 2022-06-02
  • topic: Implements the VMSP (Vertical Maximal Sequence Patterns) algorithm to find frequent subsequences in a collection of event logs. Based off the work here.
  • tiny-notes: Could be used to surface frequent patterns when digging into event sequences. The MAQUI work for recursive event exploration uses it. Tabled for later when I try to replicate the full application.

Metrics layer tools

  • date: 2020-04-20
  • topic: What I can understand from the pitch for Metric layer tools.
  • tiny-notes: Seems like a nice way to keep analytics disciplined. Not sure if it warrants a separate service though, maybe as a library that you can integrate with your existing analytics code.

Node-and-wire editors for analytics

  • date: 2021-12-20
  • topic: Notes on what I like about node-and-wire editors for working with data.
  • tiny-notes: What I would really like is the Jupyter workflow, but cells backed to a content addressable storage. So, very much like observable. In fact, don't stop at data science, make even regular programming work that way. Ex - Unison.

Writing a Recommendation System

  • date: 2021-11-01
  • topic: Describes the recommendation system behind an adaptive learning API platform for school students.
  • tiny-notes: The post never made it to the company blog, so stored here for posterity.

Code from a Forth tutorial

  • date: 2021-10-29
  • topic: What writing the Snake game in your calculator is like; following the tutorial at link.
  • tiny-notes: Concatenative programming seems pretty cool. Time to dive into a language like APL.

Change Data capture

  • date: 2021-05-30
  • topic: How materialize does change data capture; original post on their blog.
  • tiny-notes: pretty neat model, was easy enough to follow and write it up in python.
