I tried doing an INNER JOIN in Google Sheets and it was so awkward I was compelled to build my own lightweight relational spreadsheet / language / system.
Great minds discuss flops per watt.
On trying to mash up SQLite with ideas stolen from Accountants, Clojure, Datomic, XTDB, Rama, and Local-first-ers, to satisfy Henderson's Tenth Law. Viz., to make a sufficiently complicated data system containing an ad-hoc, informally-specified, bug-ridden, slow implementation of half of a bitemporal database…
( Note beforehand: I didn’t get everything. You really also have to look at his slides for the details. Thanks Christophe for posting the slides right afterwards !)
