Architecting reliable geofencing for Android without killing the battery

It happened during a quiet Friday Jumu'ah prayer. The sermon was in full swing, the room was pin-drop silent, and then it started—the aggressive, rhythmic vibrations of a smartphone echoing against the wooden floorboards. Every head in the room turned toward the sound. I felt the heat rise to my face because it was my phone, despite me being the guy who usually prides himself on having a 'smart' setup. I had forgotten to toggle the silent mode after leaving my office, and that simple oversight t

I Built a Voice Agent That Switches Languages Mid-Call on Telnyx

Translation apps interpret between two people speaking different languages. Code-switching is different: one caller switches languages mid-conversation and the agent follows them. No interpreter, no restart, no separate vendors — one Telnyx AI Assistant that detects the spoken language on every turn and replies in kind. The Telnyx code example is: https://github.com/team-telnyx/telnyx-code-examples/tree/main/ai-multilingual-code-switching-agent-python It is a Python Flask app with a simple brows

Old MCP listings do die more often — but age is the wrong field to watch

A reader named Valentin asked me a good question in the comments of an earlier post. I had published a table showing that MCP registry listings fail at wildly different rates depending on where they're hosted — Railway 66%, Vercel 8% — and argued you could use that as a prior to order a revalidation queue instead of re-probing all 10,716 entries evenly. His question: do the entries carry submission dates? Because if failure rate also climbs with listing age inside a single platform, that's a sec

Why Frontend Developers Should Care About Brand Identity Systems

We’ve all been there: you get a clean design mockup, fire up VS Code, and start writing components. But halfway through building the layout, you notice inconsistent spacing, random button variants, and color hex codes hardcoded all over the place. As developers, we love systems—reusable components, clean state management, and modular architecture. So why do we treat brand assets like an afterthought? When building Joemetry, I realized that treating a brand identity like a design system complete
