Context got commoditized. Translation is next. When my company’s acquisition closed in 2024, I thought about pursuing a psychology degree in the US. The impulse was the same one that drives URE: wanting to understand how things are wired under the hood. My wife shut it down—“Really? You know that’s not going to work”—and she was right, though neither of us fully understood why at the time. What I was actually chasing wasn’t psychology. It was context. ...
4/5 — Security as an Enabler (and “forward agency”) Series: Security Assurance — URE Case — 4/5 Start from the beginning: 1/5 — The Inception Next: 5/5 — Conclusion — Assurance Without Theater Security enables the business when it shows up with agency: not just identifying risk, but carrying enough context to propose solutions that preserve the mission. That requires a maturity shift. When security arrives late, it often speaks in “non-English.” It blocks because the system is already committed to choices no one can defend. ...
Right now, I’m working on an InfiniBand topology design for a GPU cluster. The math keeps pointing to the same conclusion: scale-out only makes sense when scale-in has topped out. It’s not about CUDA cores. It’s not about tensor throughput. It’s about tail latency. NVLink keeps GPU-to-GPU communication on-package or over short copper links — no NIC, no PCIe host traversal, no protocol stack. For small messages, that means sub-microsecond latency in the hundreds-of-nanoseconds range. InfiniBand NDR switches add sub-microsecond port-to-port latency, but once you include the full path — PCIe to the NIC, driver overhead, fabric hops, and back — real-world GPU-to-GPU latency across nodes often lands in the 3-10μs range depending on message size and topology. ...
The “Everything Is Green” Problem Here’s a realistic scenario I’ve seen in different forms across fleets (this is a composite, not a single true story with exact numbers): A training run is supposed to take ~3–4 weeks. Two weeks in, someone notices the timeline slipping. Not a crash. Not a failure. Just… slow. The job is running 10–30% behind plan, and nobody can point to a smoking gun. The dashboards look perfect: ...
