The Daily WTF

A cautionary tale about a developer (Barry) who, instead of fixing slow SQL queries through proper indexing and query planning, wrote a Python polling script that checks every 3 minutes whether database jobs completed. The script has multiple code quality issues: unnecessary array usage, string comparison against boolean literals, duplicated near-identical queries, and embedded retry logic that bypasses the team's existing job management system. The real fix would have been query optimization with indexes rather than a workaround that masks the underlying performance problem.

What? 😂

See first comment in the article…When the only tool you have is a hammer … everything gets damaged.

The story highlights a bigger issue: engineering culture often rewards visible activity over effective solutions. Barry’s script ran every 3 minutes, but the real ROI was never realized because the database remained unoptimized.
