What is eratosthenes?

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.

eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

What is Inngest?

Durable execution platform pushes into low-latency runtime and AI-agent developer workflows.

Inngest is a durable workflow execution platform built around a TypeScript SDK. The last six months ran two strategic bets in parallel: chasing AI-workflow latency (Checkpointing cut workflow duration by 50%, then Durable Endpoints extended durability into plain API handlers) and making the platform a first-class target for AI coding agents (Dev Server MCP, Agent Skills, markdown docs URLs). TypeScript SDK v4 GA in March consolidated this as the default experience.

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.

◆ Current state

eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

◆ Where it's heading

The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.

◆ Prediction

With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.

Durable execution platform pushes into low-latency runtime and AI-agent developer workflows.

◆ Current state

Inngest is a durable workflow execution platform built around a TypeScript SDK. The last six months ran two strategic bets in parallel: chasing AI-workflow latency (Checkpointing cut workflow duration by 50%, then Durable Endpoints extended durability into plain API handlers) and making the platform a first-class target for AI coding agents (Dev Server MCP, Agent Skills, markdown docs URLs). TypeScript SDK v4 GA in March consolidated this as the default experience.

◆ Where it's heading

Inngest is broadening from 'workflow engine' to 'durability primitive any TypeScript handler can wrap with step.run().' Realtime moving into the core SDK and Durable Endpoints both shrink the surface gap between 'calling Inngest' and 'writing a normal handler.' The AI-agent investments suggest they expect new project onboarding to happen via a coding agent installing skills, not a developer reading docs.

◆ Prediction

Expect Durable Endpoints to graduate from public beta (currently Next.js and Bun only), realtime APIs to expand to more frontend integrations, and the Agent Skills set to grow into the longer tail of testing, deployment, and debugging workflows.
