Happy Birthday, Harry! May your day be filled with fewer bugs than a freshman's first coding assignment and more joy than discovering the perfect algorithm. Your tireless dedication to Harvard’s undergraduate computer science program has inspired countless students—though we're still debugging our way through "Blown to Bits"!Your insightful books like "Excellence Without A Soul" remind us that education is about nurturing minds, not just filling them with data (or caffeine). Here's hoping this year brings you as much happiness as you've brought clarity—and humor—to academia. Keep inspiring generations of coders who occasionally forget semicolons but never your wisdom!
