DuckDB as the New jq
Recently, I’ve been interested in the DuckDB project (like a SQLite geared towards data applications).

I have been writing a lot more Go this past year. For those not familiar, Go favours a non-ORM, non-query-builder approach to interacting with databases. This comes naturally due to the sql package: A common interface to be used alongside database drivers. It’s very common to see actual SQL in Go, even in large projects. On the other hand, Python does not have anything in the standard library that
