The Problem Nobody Asked For (But Everyone Needs) You know that feeling when you open a news app and it’s just… noise? Thousands of articles screaming for attention, none of them knowing anything about you, your interests, or why you’d actually want to read about quantum computing when you’re clearly a sports enthusiast at 6 AM before your coffee kicks in. That’s the problem we’re solving today. News recommendation systems are the unsung heroes of content discovery....

There’s a peculiar cult in software development that I’ve been observing for years. Its members gather in code reviews, Slack channels, and conference talks, chanting their sacred mantra: “Keep it simple.” They wield simplicity like a holy relic, dismissing anything remotely sophisticated as “over-engineering,” and they’re driving the industry into a ditch while feeling morally superior about it. Don’t get me wrong—I’m not anti-simplicity. But I am deeply suspicious of dogmatism in any form, and the modern religious fervor around “simple code” has reached levels that would make medieval monks look pragmatic....

Understanding In-Memory Databases Remember the last time you waited for a webpage to load and thought, “What century is this?” Yeah, that’s what disk-based databases feel like to modern applications. In-memory databases change that equation entirely. An in-memory database is fundamentally different from traditional databases that toil away on spinning disks. Instead of treating RAM as a temporary cache, in-memory databases make it their primary home. This architectural decision isn’t just a minor optimization—it’s a paradigm shift that rewires how applications handle data access....

So you’ve decided to build your own file system. Congratulations on choosing the software equivalent of constructing your house foundation while simultaneously building the walls, roof, and plumbing. I admire your ambition, truly. But let me save you six months of debugging and at least three mental breakdowns by explaining why this is almost certainly a mistake. The Seductive Trap of “We Can Do This Ourselves” Here’s the thing about file systems—they’re deceptively simple in theory....
