Questdb

Inspired by Moomtower's exploratory toolkit | Solves problem of 'how much time I should give the spread, and how much more it'd cost?'

Can also plot slices of surfaces. Interactive and comes with rich hover data and projection on different dimensions to help you gauge fear and customer interest and find potentially misquoted options.

Transforming raw data into something that's more meaningful - how I optimized the app via lazily-evaluated vectorized polars operations and by pushing the filtering up in the data pipeline

Just trying out Grafana with real (time) data

Wrapping questdb-cli in rlwrap with dynamic autocompletion of live table names and QuestDB SQL keywords.

QuestDB comes with a very nice web console, but there's no CLI, so I wrote one.

I wanted to set up my computer for more advanced market research that requires tons of data, in this post I'll share how I solved some of my problems.
