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 Ory?

Ory polishes OAuth2/OIDC ergonomics and adds live event observability to its Network.

Ory pairs open-source identity components with the managed Ory Network. The recent run is incremental: OAuth2 performance, CLI JWK export, customizable login labels, and OIDC flow refinements, alongside a new live event stream and events page in the Network.

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.

O
Ory

0.0

Ory polishes OAuth2/OIDC ergonomics and adds live event observability to its Network.

◆ Current state

Ory pairs open-source identity components with the managed Ory Network. The recent run is incremental: OAuth2 performance, CLI JWK export, customizable login labels, and OIDC flow refinements, alongside a new live event stream and events page in the Network.

◆ Where it's heading

Two threads run in parallel: steady refinement of the OAuth2/OIDC surface (audiences, token hooks, native recovery) and a move toward observability, giving operators real-time visibility into registrations, logins, and token issuance.

◆ Prediction

Expect the Network's event and observability surface to keep expanding, with continued ergonomic work on OIDC flows for native and mobile clients.
