Two coroutines, one journal: a Restate restart demo
Both preparation steps had finished when I stopped the Node process. The Restate server stayed running. After I started the service again, the pending invocation returned ["A", "B"] , and the…
- Two coroutines, prepare-a and prepare-b, each with generator-based steps
- Interruption occurred mid-process, file verified executed effects
- Service implemented in service.mjs with dependencies @restatedev/restate-sdk
Why Pay for the Smartest Model Every Time?
Originally published on wrightfunctions.com , where the demos are live. A restaurant doesn't send every order to the head chef. Toast goes to the line cook.
- Intelligent routing, cascading, distillation, and caching reduce large language model pricing.
- Requests directed to most powerful model only when necessary, cutting costs up to 85%.
- Distillation trains smaller model on larger model's outputs for faster, cheaper usage.

Node.js Logistics PDF Search: Latency Caps with Budgeted Fallback Telemetry
TL;DR: Put a deadline around vector retrieval in Node.js, return keyword matches when that deadline expires, and count the switch as one low-cardinality metric.
- Implement deadline for vector retrieval in Node.js search
- Use small label set for telemetry: mode, outcome
- Calculate retention based on event bytes and days
StateBench’s matched traces make a better reading test
At one point in my generated StateBench example, g holds 99 and c holds 57. Three versions of the next update all leave g at 57: g <- c; g <- (g + 58) mod 100; g <- 57; The answer agrees.
- StateBench introduces matched traces for clearer reading tests
- Four program types: periodic, solvable, aperiodic, r-trivial
- Matched traces reveal language model's state update understanding
