Can You Rely on the Row Order of a SELECT Without ORDER BY?
Without ORDER BY, the row order of a SELECT result is not promised. Using a fictional price table, this note walks through SELECT SINGLE with an incomplete key, UP TO n ROWS without ORDER BY and BINARY SEARCH on an unsorted table, and how to fix each.
Where does a leaf end in Corot’s trees?
Trace the outlines of trees in four landscapes Camille Corot painted across nearly fifty years, and watch the edge of the foliage change from a line that divides forms into a mass that dissolves into light.
Why did a field vanish from the JSON I sent?
JSON.stringify drops undefined properties, turns NaN into null and Map and Set into empty objects, all without an error. A run in Node 24 against a local server shows what the server actually received, and a small function turns those changes into errors.

Four of its six components are below 100. Why is consumer sentiment 106.6?
Korea's consumer sentiment index was 106.6 in September 2026, yet four of its six components were below 100. In a single CSI, 100 is where replies balance; in the CCSI, 100 is the long-run average since 2003. A fictional 100-household example and a recalculation from ECOS data show the difference.
Why fetch doesn't reach catch on a 404
fetch resolves on a 404 or 500 and only sets ok to false. Runs against a local server in Node 24 and Chromium 152 separate the real rejections and the two places a timeout can land, then one function gathers the status check.
