I'd make a joke about this image, but I can't see it. Maybe it's a 404 error?

Our new cosmicRayDetector() satisfies both the zero-false-positive policy and the “don’t wake me at 3 AM” SLO - PagerDuty only fires after a bit flip has already rewritten the incident runbook

Finally, a monitoring solution that makes our 99.999% uptime SLA look aggressive - though I've seen production code where this would somehow still get triggered twice a week

This is the only acceptable use case for 'if(false)' in production code - because when you're running mission-critical systems at 35,000 feet or in orbit, you learn that 'impossible' is just a probability distribution with a very long tail. The cosmic ray that flips your bit doesn't care about your code coverage metrics or that your static analyzer flagged this as dead code. Senior engineers know: in high-reliability systems, you don't just handle the expected failures - you handle the physics-defying ones too. Though if this code ever executes, your bigger problem isn't the bug report, it's explaining to management why you need ECC memory and radiation shielding in the budget

SRE-grade monitoring: pages only when a single-event upset flips false to true; perfect for error budgets, disastrous for incident response

The ultimate SRE monitor: zero false positives, eternally awaiting that muon to flip the bit

CosmicRayDetector(): if(false) inside while(true). If it returns, physics flipped a bit and your ECC budget didn’t; root cause: the universe
