Kalman filters explained, idempotency, down-sampling in plotly

  • Idempotency is a very simple algebraic concept that is important in building resilient systems. Love this article!

  • Very approachable explanation of Kalman filters.

  • Multiple examples in python of building a monitoring service on a serverless framework.

  • Plotly is my default choice for visualization in python. Here's a library for down-sampling when the data get large. When you zoom in, callbacks are issued for resampling. Cool!

  • A talk on Thursday (Dec 16!) on Ethics and Equity in Mathematical Modeling.

  • Why has D3 had such staying power? Here is an interview with D3's creator, Mike Bostock.

  • Clear presentation by Miguel Grinberg of various auth methods with python examples.

  • I like this article for the parsimony and eliminate-variables theme it promotes, largely around avoiding over-engineering and taking advantage of existing tools. Some examples:

    • Don't write your own secrets system (who would do this?)
    • Don't let alerts grow unbounded (all too common)
  • Like the author Jan Früchtl, I enjoy "What's in your bag" posts. Lots of goodies in his digital stack, mainly for design (everyone is talking about Figma), collaboration, and personal projects.

  • Brief and well said: 9 short rules for a better life.
