The Ambulance Behind the Truck: Why TCP Struggles in the Datacenter, and What Homa Does Differently
A transport protocol out of Stanford treats messages, not streams, as the unit that matters — and prioritizes by what's left to send, not what arrived first. Notes from throughput work on F5 ADC and S3/MinIO infrastructure carrying AI workloads.

Teaching a Model to Answer Instead of Talk
Jev, Laya, and a weekend spent building a UI for a category of model I didn't know existed — typed-decision models that skip generation entirely and hand back a calibrated probability instead.

Consistent Hashing from Scratch, and Why Cloudflare Deleted 90% of It
I built a consistent-hash ring in 40 lines of Python and measured everything — load imbalance, 32-bit collisions, what moves when a server dies — to understand how Cloudflare recovered ~100 TB of RAM by asking how much randomness they actually needed.

A From-Scratch Tour of OpenFlow, From the Wire Up
Building a toy OpenFlow switch and controller in ~600 lines of Python, then working bottom-up through PHY, parser, TCAM, pipeline, and actions to show why the protocol's design is downstream of memory technology and a 20-cycle-per-packet budget.

IPv8 and the Internet's Eternal Transition Problem
A reflective breakdown of the IPv8 draft proposal — compatibility claims, zero-prefix IPv4 embedding, ASN routing limits, physics-aware routing metrics, and the risks of collapsing internet infrastructure into a centralized zone server model
