The Classic Light Bulb Problem
Description
An illustration depicting a classic programmer joke. Against a dark blue background, two cartoon hands are shown reaching for a compact fluorescent light bulb. The text is split into a question and an answer. The top text reads: 'How many programmers does it take to change a light bulb?'. The bottom text provides the punchline: 'None - It's a hardware problem.'. This meme is a timeless piece of developer humor that plays on the stereotype of software engineers deferring any issues outside of their code to other departments. For senior developers, it's a relatable and amusing take on the strict division of responsibilities (and blame) between software and hardware teams, perfectly encapsulating the 'not my department' mindset that can be prevalent in tech organizations

Why don't programmers change light bulbs? Because they'd first have to write a 30-page RFC, debate the merits of LED vs. incandescent in a two-hour meeting, and then ultimately decide to create a ticket for the facilities team to handle the physical layer
Sure, it’s a hardware problem - right up until the firmware team asks why your JSON config turned the bulb off in prod
After 20 years in the industry, I've learned the real answer is: one to open a JIRA ticket, three to debate whether it's a P1 or P2, two to argue it's actually a feature request for smart bulbs, and an entire DevOps team to implement Infrastructure as Code for automated bulb replacement - only to discover the real issue was someone forgot to flip the switch
The real answer is that it takes one programmer to open a JIRA ticket titled 'Light bulb replacement' with priority P4, assign it to the facilities team, add it to the infrastructure backlog, and then spend three sprint planning meetings discussing whether this should be handled by DevOps or if it requires a cross-functional working group to establish a Light Bulb Replacement Framework (LBRF) with proper observability and rollback capabilities
Blameless postmortem: the lumen service failed at Layer 1, so we opened a Facilities Jira, marked the bulb as an external dependency, and preserved our error budget
How many engineers to change a light bulb? Zero - it's outside our bounded context; we ship ToggleLight(), mock it in tests, and let Facilities own the side effects
None - we'd deploy a Kubernetes pod to simulate photons via shaders before admitting it's not a software abstraction leak

10. First one changes a bulb, second one tries to understand the joke. Comment deleted
11. third one explains the joke to the second n00b Comment deleted
Too complicated and dragged out, Mr. Boring Man. Comment deleted
this was actually pretty good lol Comment deleted
There are 10 types of people in this world. First: who understand binary numbers. Second: who don't. Comment deleted
I almost fell for that Comment deleted

did you really hash 2... Comment deleted
yes md5sum Comment deleted
MD5 = 💩 Comment deleted
only for cryptographic purposes, for everything else it's actually quite nice since it's quite fast Comment deleted
Holy f did you really hash 2? Comment deleted
