Previously, I promised to write three posts about dispatching irritants with J. This, my third post, is proving more irritating than the others, so I will split it over two posts. SQLite, by many estimates, is the most widely deployed SQL database system on Earth. It's everywhere.

SWAG a J/EXCEL/GIT Personal Cash Flow Forecasting Mob
While browsing in a favorite bookstore with my son, I spotted a display of horoscope themed Christmas tree ornaments. The ornaments were glass balls embossed with golden birth signs like Aquarius, Gemini, Cancer, et cetera, and a descriptive phrase that “summed up” the character of people born under a sign.
