Why we ditched the knowledge graph approach for agent memory

Every other week someone drops a new memory layer for AI agents. Most of them do the same thing-> take conversation history, extract entities and relationships, compress it into a knowledge graph. The problem is thats lossy compression. You are making irreversible decisions about what matters at...

How I Built a Stateless 3D Asset Pipeline That Manages 1,000+ Models for Free

3D assets are a nightmare for Git. They are heavy, binary-rich, and bloat repository history faster than you can say "Pokemon." When building the Pokémon 3D API, I hit a wall: Manual Optimization: Resizing textures and compressing meshes for every model was exhausting. Contributor Friction: Arti...

Building a Resilience Layer for Mobile AI: How I handle 429s, Provider Fragmentation, and Streaming in React Native

Most React Native AI integrations I've seen share two failure modes: they're locked to one provider, and they have no strategy for rate limits. After rebuilding the same glue code across multiple projects, I packaged it into react-native-ai-hooks v0.6.0. The Core Problems Provider Frag...

AI Crash Course: Prompt Engineering

Read the previous blog in this series: Hallucinations. Prompting is the primary way we provide input to AI models: when we need a model to generate something for us, we begin the process by prompting it with a plain-language request to complete the task. When we’re having simple, back-and-forth per...

Building a 3-Class Lung Cancer Image Classifier with TensorFlow and Flask

Medical imaging is one of the most rewarding spaces to apply deep learning. Pathologists spend years learning to distinguish subtle visual patterns in tissue samples, and even then, fatigue and caseload pressure can creep into decisions. A well-trained CNN does not replace that expertise, but it can...

What Is the Best Website for Exchange Rates? (2026 Guide)

If you search "best website for exchange rates," you get a dozen contradictory answers — Google Finance, XE, Wise, Reuters, your bank's app. They all show a number next to a currency pair, and they're all a little different. Which one is right? The honest answer: "best" depends on what you're doing...

Bugmageddon Is Real. But Bug Discovery Isn’t the Real Bottleneck Anymore.

The scary part about the new "Bugmageddon" story is not that AI can find vulnerabilities faster. That part was inevitable. The real shift is that bug discovery is getting cheap. And once that happens, the bottleneck moves somewhere else. Attackers need one exploit that works. Defenders have to so...

I needed resumable LLM streams in Go — so I built streamhub

If you've built anything that streams LLM responses over SSE, you've probably hit this: the user refreshes the page, or their network blips, or the load balancer routes the reconnect to a different instance — and the stream is just gone. The generation keeps burning tokens on your backend, but the c...
