summary

Small projects and big fixes: a Berlin chapter reports rebrand to Code Curious after 1,500 students, 40 workshops and 300 volunteer coaches. One demo streams large CSVs from a Rails app by using Rack response bodies and Postgres COPY to avoid timeouts. A production table with JSON blobs shows 1.2s outliers reduced to ~10ms by splitting JSON into columns. Practical notes include code review checklist rules, a GDS DSL for composable data, Jupyter+Ruby data science with SVM Kit, and a Rails web UI that reliably controls factory machines.
