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 Stream?

Stream's logistics platform ships steady monthly digests: planning, orders, mobile, no pivots.

This feed is Stream, a delivery and transport-management platform (not the chat/video devtool of a similar name), publishing dated monthly release digests. Each month bundles dozens of scoped improvements across Planning, Orders, Vehicles, the driver mobile app, Public API, and reporting, plus a long fixes list. The cadence is reliable and the work is broad but incremental.

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.

Stream's logistics platform ships steady monthly digests: planning, orders, mobile, no pivots.

◆ Current state

This feed is Stream, a delivery and transport-management platform (not the chat/video devtool of a similar name), publishing dated monthly release digests. Each month bundles dozens of scoped improvements across Planning, Orders, Vehicles, the driver mobile app, Public API, and reporting, plus a long fixes list. The cadence is reliable and the work is broad but incremental.

◆ Where it's heading

The arc is operational maturity, not repositioning: automatic run costing, an Operations Monitor, a rebuilt Clients screen, expanded Public API endpoints and webhooks, and continual planning/mobile refinement. It reads as a maturing vertical SaaS deepening its existing surface for logistics operators rather than opening new categories.

◆ Prediction

Expect the same monthly digest cadence with continued Public API and integration expansion and further planning/mobile polish; no directional shift is visible in these entries.
