A collection of thoughts and experiments that at one point occupied my time, some still do. These are the things happening in my idle cycles.
A few notes on an interesting software design I've been noodling on. I'm still trying to untangle how to foster organic growth in software systems.

I have found myself repeatedly arguing against architectural complexity in favor of "just let the database do that" and I thought it was probably a good idea to further develop an intuition for performance against some hard numbers.

I was thinking again about data serialization in Python after
reading an
interesting post that suggests
using functools.singledispatch as a way of
encapsulating JSON encoding per datatype and it got me thinking
again about XML.
I noticed some latency in a unit test on a single machine. It turned into a bit of a rabbit hole that took some time to get to the bottom of. I think I at least understand some libraries and tools better as a result though!

I'm getting the feeling again that not only is your test framework making things worse but also the ease of installing libraries exacerbates issues of quality in the design of projects.
