Ask HN: Old Unix technologies like cron and SSE in modern workflows?

I've been in the industry for over a decade and find myself repeatedly returning to battle-tested UNIX technologies despite the constant stream of new frameworks and tools.

Cron jobs still power critical scheduled tasks across our infrastructure. Server Sent Events handle real-time updates more efficiently than many WebSocket implementations I've tried. Shell scripts glue together components that modern architectures claim to integrate seamlessly.

I'm curious how others are leveraging these older technologies in modern stacks. Have you found creative uses for old UNIX tools that outperform newer alternatives? Are there specific combinations of old + new that work particularly well? Any war stories where a simple UNIX solution saved the day when modern tools failed?
