Trust Me Bro We Don't Need Caching

system-design-memes, caching-memes, interviews-memes, backend-memes, database-queries-memes | ProgrammerHumor.io

You know that one senior dev who shows up to the system design interview with a conspiracy theorist's wall of chaos? Red strings connecting random boxes, sticky notes everywhere, and somehow they're convinced their architecture that hits the database 47 times per page load is "fine actually."

Meanwhile they're out here explaining why caching is "premature optimization" while their API response times are measured in geological epochs. Sure buddy, let's just query that unindexed table with 50 million rows on every request. What could go wrong?

The confidence-to-competence ratio here is absolutely off the charts. They've got the energy of someone who's never been paged at 2 AM because Redis went down and suddenly realized why everyone kept saying "just cache it."

The Tech Company Ecosystem: A Field Guide

Ah, the natural habitat of the modern tech company, expertly dissected! The corporate ecosystem where CEOs float around like mythical beings while backend engineers blast gangsta rap and devise t-shirts with obscure references that only five people on Earth understand. The hierarchy is perfect - from the "office ninjas" who somehow conjure free snacks from the void to the "dev/SEO shamans" who perform their dark rituals of traffic generation. Meanwhile, customer support maintains their superhuman ability to say "no" without actually saying "no" - a skill more valuable than any coding language. And let's not forget the servers - the only ones actually working 24/7 without complaining about the coffee quality or demanding ping pong tables. Silent heroes indeed. The true magic of tech companies isn't the technology - it's somehow convincing everyone that Nerf gun wars and free snacks compensate for existential dread and imposter syndrome. Brilliant!
