sq: A General Swiss-Army Knife for Data — There are lot of ‘Swiss Army knife’-esque data 'multitools' around (such as xsv for CSV or jq for JSON) – think of this one as being like jq but for all sorts of formats and systems. You can import an Excel sheet into a Postgres table, move query results from SQL Server to SQLite, export an entire database to CSV.. all sorts of things. Many formats are supported and Postgres, SQLite, SQL Server and MySQL are the supported RDBMS so far.

Creating Amazon Timestream Interpolated Views using Amazon Kinesis Data Analytics for Apache Flink — Sounds like a bit of buzzword bingo in the title, eh?
