Bloom Filters for AI Agents: The Small Cache Trick That Saved My Retrieval Pipeline

Bloom filters felt like a purely academic data structure—until an agent pipeline started repeating work. At that point, they became immediately practical. Problem The system needed a fast, low-cost way to check whether something had probably been seen before. Not certainty. A strong enough signal to avoid redundant work. Failure Mode The agent repeatedly: revisited...

The Question Nobody Asks Before Picking a Mobile AR Platform

Most teams pick a framework and live with it for years. Here's how to get it right the first time. I evaluated three platforms for a client porting an Android AR app to iOS. The project was 3D object scanning for warehouse operations. It needed to replicate existing camera-based capture workflows, integrate with a React backend, and eventually ship as a reusable third-party SDK. Most teams sk...

Help! The wrong JST Connectors (and 4 2000 mAh batteries) 🔋

I'm still working on my droid build, but I've discovered yet another snag. I picked up some lightweight 2000 mAh rechargeable lithium batteries but upon arrival I realize that I don't actually know what a "Micro JST 1.25 connector plug" is. ( I think this has solidified how important it is in an electronics project to research the physical pieces needed.) Is micro JST even a real thing? The bat...

Why Python is the best first language (and when it isn't)

Search "what language should I learn first" and 90% of the answers will say Python. That's not a conspiracy, not hype, not a course sponsorship. There's real reason behind it. But there's also context those answers ignore — and ignoring context is what makes a lot of people start with the right language for the wrong goal. So let's be honest about both sides. Why Python makes sense ...

Se você pesquisar "qual linguagem aprender primeiro", 90% das respostas vão falar Python. E não é conspiração, não é hype, não é patrocínio de curso. Tem razão nisso. Mas também tem contexto que essas respostas ignoram — e ignorar o contexto é o que faz muita gente começar com a linguagem certa para o objetivo errado. Então vamos ser honestos sobre os dois lados.

How Long Does a UK Number Port Actually Take? Data From 480 Real Ports
