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 Instatus?

Instatus has grown from status pages into a Slack-native incident response platform.

After launching Instatus 2.0 in mid-2025 with monitoring and incident response added to the existing status-page core, the past two quarters have been about polishing the incident lifecycle. The January release was the biggest expansion: full /incident command set in Slack, dedicated per-incident channels, postmortems from chat, and emoji-driven incident creation. Recent months added recurring maintenance windows, third-party status-page aggregation (Statuspage), General Notices, Freshstatus migration, Zapier, Jira, WhatsApp, Resend, and Brevo integrations.

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.

0.0

Instatus has grown from status pages into a Slack-native incident response platform.

◆ Current state

After launching Instatus 2.0 in mid-2025 with monitoring and incident response added to the existing status-page core, the past two quarters have been about polishing the incident lifecycle. The January release was the biggest expansion: full /incident command set in Slack, dedicated per-incident channels, postmortems from chat, and emoji-driven incident creation. Recent months added recurring maintenance windows, third-party status-page aggregation (Statuspage), General Notices, Freshstatus migration, Zapier, Jira, WhatsApp, Resend, and Brevo integrations.

◆ Where it's heading

The arc is clear: Instatus is going head-to-head with Atlassian's Statuspage and Better Stack on a single integrated stack — monitoring, incident response, public communication. The Slack-native push is the real differentiator; incident commanders rarely want to leave Slack. Migration tools (Freshstatus) and third-party aggregation (Statuspage import) point at land-and-expand against incumbents.

◆ Prediction

Expect on-call and scheduling integrations next, expanded migration tooling for other status-page incumbents (Better Stack, Status.io), AI-powered incident summarization and postmortems, and broader monitoring coverage — likely synthetic and browser checks.
