The Recursive Nature of Debugging
Description
A meme with the text 'Debugging is like being a detective in a crime movie where you are also the murderer.' This is a witty and relatable analogy for the process of debugging code. As a developer, you are trying to solve a problem that you yourself created, often inadvertently. The meme captures the sense of irony and frustration that comes with this realization. Senior developers, in particular, can appreciate this sentiment, as they have often had to debug complex issues that were the result of their own subtle mistakes or oversights

The six stages of debugging: 1. That can't happen. 2. It happened. 3. That shouldn't happen. 4. Why is that happening? 5. Oh, I see. 6. How did that ever work?
Sprint planning: we budget for the iceberg we see, pad for the mass we suspect, then deploy and watch an awakened 2003 Perl daemon redefine “Definition of Done.”
The scariest part isn't the monster at the bottom - it's realizing that every architectural decision you've confidently defended in the last decade lives somewhere in that middle layer
The iceberg perfectly captures the senior engineer's journey: Junior devs live confidently in the sunshine above water, mid-levels nervously explore the visible depths they can see, and seniors? We're down in the abyss, discovering yet another layer of 'unknown unknowns' every time we think we've hit bottom - usually right after confidently telling a stakeholder 'this should be straightforward.'
Known unknowns are Jira epics; unknown unknowns are the ones that nuke your SLOs at 3AM
Software is an iceberg: the part you know is in the README, the part you know you don’t know is in the risk register, and the abyss is a prod cron job called do_not_delete.sh running as root since 2011
Every architecture diagram shows the iceberg; the postmortem discovers the kraken - summoned by a retry storm, stale DNS, and the implicit 30s timeout you inherited from 2009
