The email arrived on a Tuesday morning: "Your cloud bill for last month: $2.4 million." The CFO's response was immediate: "That's 3x our budget. What the hell are we running?" The answer? Nothing special. Just a standard data analytics workload that happened to cross availability zones. A lot. Turns out, 80% of that bill—nearly $2 million—was data egress fees. Not compute. Not storage. Just the pr
I kept watching the same thing happen. What I Built It's a 3D interactive sales simulator. I call it a flight simulator for software — except instead of flying a plane, you're walking a non-technical client through the risk inside their own infrastructure. The Map You feed it a simple JSON file describing your client's tech stack. It reads it and instantly draws a floating, 3D web of nodes — s
OK, let's talk about Microsoft's new Fairwater "AI factory,” (The quotes here are doing a lot of work… do we REALLY need a new name for this? It’s so dumb). They're calling it the world's most powerful AI datacenter. Cool. Millions of GPUs. Liquid cooling. Storage stretching five football fields. Here's what they're NOT telling you: the math on utilization is going to be BRUTAL. If these chips ran
I was building a side project that needed image compression. My first instinct was to look for an API — TinyPNG, Cloudinary, something with a POST endpoint. if (blob.size >= file.size) { Try the requested quality first. If the output is bigger, walk down through lower qualities until something sticks. As a last resort, if WebP output is still larger, fall back to JPEG entirely. Not elegant, but it
Ever had users sign up with [email protected] or [email protected]? Disposable email addresses are a headache for any app that relies on real user contact. I built burner-bouncer to solve this — a zero-dependency libra
I finished an English series on the way I think ordinary people can start using AI for real work. The point is not to become an AI expert first. The point is to have one place where you can say what you want, give the tool access to the right folder, and check the result. Anything important still needs a human pause: publishing, deleting, paying, or authorizing. My preferred starting point is simp
When you bind Ctrl+S to "save" in a web app, do you check event.key === "s" or event.code === "KeyS"? The honest answer is "I don't remember, I copy-paste from Stack Overflow." Until a Dvorak user reports the shortcut is broken — or a Japanese IME user reports it fires mid-composition. This is a live inspector for KeyboardEvent: press any key (or combination), see every field — key, code, keyCode,
I got tired of not knowing why users were dropping off in my app. Heatmaps show you where people click. Analytics show you when they leave. But nothing tells you how they felt while using it. So I built SessionMood API — a REST API that scores user mood in real time based on behavioral events. You send behavioral events from your frontend: fetch("https://session-mood-api-production.up.railway.app/
