From PNG to 3D Print: Building a Browser-Based STL Pipeline

If you've ever tried to 3D print a logo, a QR code, or a flat illustration, you know the usual pain: open Fusion 360 or Blender, trace the outlines, extrude, export, pray the mesh is manifold. It's a 30-minute detour for what should be a 30-second task. Over the last few months, I've been building a set of browser-based tools that collapse this entire workflow into three clicks: upload image, pic...

Uber System Design: A Comprehensive Guide to Building a Real-Time Ride-Sharing Platform

If you ask developers which product is one of the best examples of real-world system design, Uber almost always comes up. And honestly, for good reason. Uber is not just a taxi-booking app. It is a real-time distributed system that has to make thousands or even millions of decisions every minute.

I built a Claude Code plugin that refuses to agree with me

I typed this into Claude Code the other day: ❯ claude code is better than codex ⏺ Noted. No pushback. No "on what metric?" Just a polite nod. That's the bug. Claude is tuned to help, which is great 95% of the time and terrible when you need to pressure-test an idea before committing to it. "What could go wrong with this?" produces a gentle bulleted list.

Protobuf: Why Google's Servers Don't Speak JSON

https://www.youtube.com/watch?v=OsyKxWxGtiI Your API returns a user. Three fields — an ID, a name, a bit for active. That exact payload, as compact JSON, is forty-one bytes on the wire. As protobuf, it's twelve. But compactness is the least interesting thing about protobuf. The real reason Google built it is something JSON fundamentally cannot do. The JSON bill you pay on every request ...

Tizen - Javascript embedded video failing

I'm trying to show trailers in a webapp, it's working fine for normal browsers, as well as android apps. However, when I package the javascript in my tizen app, it fails to show the embedded video, it just plays the sound. There are other weird things too, like a button not completely updating either. I have tried multiple different courses of action, but AI seem unable to figure out the issue. He...
