TIL: Columbia (US places) and Colombia (South American country) have different spellings, though they sound identical.
Both named after Christopher Columbus but spelt differently in English vs Spanish, I guess?

Oracle Hint of the Day: INDEX_FFS for a Fast Full index Scan.
When you're really trying to tell the optimizer how you feel about that full table scan suggestion😂
SELECT /*+ INDEX_FFS ( o order_pk ) */ COUNT(*)
FROM order_items l, orders o
WHERE l.order_id > 50
AND l.order_id = o.order_id;

Interesting issue in OpenJDK's UUID.compareTo(): It uses signed comparisons, which leads to unexpected sorting when the highest bit in either word is set. It can't be fixed since altering a sort order between versions is a big no-no.
