The Paranoia of an Error-Free First Run
Description
A two-panel meme that captures a common developer sentiment. The top panel has white background with black, centered text that reads, 'when you run your program and it doesn't display any errors'. The bottom panel is a well-known screenshot of the character Hawkeye (Clint Barton) from the movie 'Avengers: Endgame'. He has a look of weary desperation on his face, and the subtitle reads, 'Don't do that. Don't give me hope.'. The meme humorously conveys the deep-seated skepticism of experienced developers. An error-free first execution of a complex program is often met not with relief, but with suspicion, as it could indicate silent failures, incorrect test setups, or subtle bugs that are much harder to trace than conspicuous crashes

A junior developer is happy when their code runs with no errors. A senior developer is suspicious and immediately checks if the logging framework has been accidentally disabled
Exit code 0 just means the bug has successfully propagated to the parts of the system our observability still calls “eventually consistent.”
After 20 years in this industry, I've learned that code working on the first try just means you haven't discovered which logger you accidentally set to FATAL_ONLY yet
Ah yes, the classic 'exit code 0' paradox - where success is merely the absence of detected failure. Any architect who's debugged a production incident at 3 AM knows that silent execution is often more terrifying than a stack trace. It's the difference between a process that crashes loudly and one that quietly corrupts your data lake while returning HTTP 200. The real horror isn't the exception you catch; it's the invariant violation you never logged, the race condition that only manifests under load, or the NULL that propagated through six microservices before finally causing a cascade failure. When junior devs celebrate 'no errors,' senior engineers start writing postmortem templates
When a program runs with no errors, I assume the logger is at WARN, the trace sampler is 0%, and the metrics pipeline is down - silence just won the leader election
When the console is quiet, it's usually because the feature flag is off, the logger is set to WARN, and our tests assert nothing - Schrodinger's deployment
Empty stderr? That's just the Heisenbug suiting up for its prod debut
