### [2023-06-19] UPDATE: Just tried to use my instructions again on a fresh install and it failed in a number of places. 
###.   Not sure if I'll update this gist (though I realise it seems to still have some traffic), but here's a list of 
###.   things to watch out for:
###      - Check out the `nix-darwin` instructions, as they have changed.
###      - There's a home manager gotcha https://github.com/nix-community/home-manager/issues/4026

# I found some good resources but they seem to do a bit too much (maybe from a time when there were more bugs).
# So here's a minimal Gist which worked for me as an install on a new M1 Pro.

Python relative imports in AWS Lambda fail with attempted relative import with no known parent package

The Problem

In AWS Lambda if I attempt an explicit relative import like this

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

The aim is to develop a simple generic crossfilter interface for timeseries data. The tag line for crossfilter applies: we want fast multidimensional filtering with coordinated views.

We'd like a consistent ui for visualizing/querying/filtering all columns with visual summarizers/selectors appropriate to a column's type (e.g., brushable histograms for numeric types, selectable histograms for enumerated types, typeahead keyword search for text, etc.).

I'd like it to be useful primarily as a table filter and query tool, but provide simple summary visualizations and statistics of the current selection. As in the various crossfilter demos, any data visualization should also function as part of the query interface.
