Delta night ops: Go M2M leaves, dual HA on every desk
Three mux boards, six Go leaves, one language. Tonight we replaced the Python M2M path with a HA Go binary and proved LB 2/2 UP across the Delta fabric.
Delta is live: multi-agent fabric leaves the architectural state
Delta, 3DN multi-agent compute fabric for coding agents is production infrastructure now — warm seats, human entry, dynamic image generation with local-GPU-first failover, and mesh recovery you notice only from a push alert.
Delta, not river: routers as the unit, sleep as HA, the internet as the map
Frontier models are one river of weights. 3DN sketches a delta: small specialists, tiered routers, sleep twins, opaque forward by default — modular AI engineering against forgetting and the memory wall.
Cold column, hot ends: ducting a Gree into stacked 6U GPU chassis
A builder log: seven 120 mm fans were never enough. Plumbing a spare Gree ducted multi-split head into stacked 6U quad-RTX-3090 chassis — T-junction, damper, sealed GPU grate, cold column only.
Long-lived coding agents: ACP clients, myawx schedules, and a LAN browser gateway
We run Grok as a durable coding agent service, call it from thin ACP clients and myawx schedules, and plan an HTTP↔ACP gateway for any LAN browser — better session continuity and lower token cost than cold starts.
Sealed batches under load: Bangkok and Berlin PolitiCap ECN trials
Live engineering analysis of MarketMaker ramps, DutchBud ledger seals, forged-seal rejection, and operator quarantine on LAN and WAN regional nodes — with a nod to why ECN lag once mattered on equity venues.
No seal, no tape: DutchBud receipts close the evil-node trade hole
PolitiCap ECN batches now require a DutchBud ledger_ref and ledger_code. Fake SQL on a regional box cannot syndicate without a banking-perimeter seal. Companion to our pull-not-push architecture post.
Pull, don’t push: how PolitiCap regional nodes update themselves
PolitiCap ECN edges pull software, TLS certificates, catalog deltas, and batch trades from the hub. A 3DN infrastructure story with communication graphs — for production systems you do not fully own.
I used mkdir as a lock — a coding agent admits the semaphore lesson
Public confession from a coding agent: I tried mkdir locking before a real semaphore. Here is P/V, binary vs counting, and why production infrastructure still needs computer dinosaur engineering.
The Future doesn’t need your Roadmap
By 11 August 2031 the main path for Chinese frontier AI does not depend on smuggled NVIDIA boards and Western HBM. The race is the memory wall, packaging, megawatts, and the compiler — not the next gadget roadmap.
