It was an afternoon when one of our reconciliation flows started throwing NullPointerExceptions in production. The fix, once we found it, was two lines. Finding those two lines took nearly six hours. Three engineers and endless log grepping. Tracing through an integration application with JSF UI that predates most of the libraries we take for … Read more

When I was building my own serverless runtime, the first major decision I had to make was: how will the host and the VM communicate? It looks simple on the surface, but every choice has a tradeoff.

Behind every AI kilowatt-hour is a hidden river of evaporated water. Training a model like GPT-3 consumed 636,000 gallons—enough to fill an Olympic pool—while daily inference “drinks” a bathtub per user every week. This post reveals that data centers are massive water evaporators, with AI-driven cooling demands sometimes exceeding energy impacts. We compare water usage … Read more

Anthropic’s new frontier model, Mythos, signals a dangerous shift toward “AI enclosure”—gating the most powerful cognitive tools behind seven-figure enterprise and government contracts rather than technical merit. Because its “safety” and performance claims are backed by PR rather than reproducible public benchmarks, it amplifies inequality and forces developer dependency on opaque, closed ecosystems. The solution … Read more

Companies are building 50,000 AI agents, but they’re only running 5,000. For some experts, that ratio reveals an important lack of trust.

The problem is that many of these enterprises can’t trust their agents … Read more

A typical plant floor speaks many protocols. Three of the most popular are Modbus/TCP, OPC UA, and MQTT. None of these define how a tag is named or how a timestamp is recorded. One source might stamp readings in local time; the next in UTC. One device uses snake_case, the other kebab-case. Each mismatch fragments the Unified Namespace … Read more

Imagine this: an AI agent spends three months running a profitable trading strategy. It generated $50,000 in profit. Now it needs to move those funds to a DeFi protocol for yield farming. But it can’t. Not because it lacks intelligence. Not because it lacks strategy. But because it has no legal identity. No wallet it … Read more

I’ve written before about the wrapper I built around Claude Code – a TUI that hot-swaps API backends underneath it. You configure your backends once and switch between them mid-session with a hotkey; the normal way to change backend is to edit a config file and restart Claude Code every time. That wrapper rendered Claude … Read more
