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....

If you’ve ever built a WebAssembly application and watched it run slower than you expected, you’re not alone. The good news? WebAssembly has the potential to deliver near-native performance in the browser. The catch? You need to know how to unlock that potential. I’ve spent considerable time wrestling with WebAssembly performance bottlenecks, and I’m here to share what actually works. This isn’t your typical “use -O3 flags and call it a day” guide....

When your manager casually mentions that the company is “mandating AI pair programming for all new features” in the same tone they’d use to describe a new coffee machine, it hits different. But before you dust off your protest signs, let’s talk about whether unionization is actually the answer—or if we’re solving the wrong problem entirely. The AI Pair Programming Moment We’re Living In We’re at an inflection point. Artificial intelligence coding agents are no longer science fiction—they’re in your IDE right now, probably sitting there like an overeager intern who never sleeps, never asks for vacation, and never complains about pull request feedback....
