tulpa vs wasserportal: at a glance
What is tulpa?
The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.
tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.
What is wasserportal?
A Berlin groundwater scraper grew a full IoT publishing pipeline in two days.
wasserportal scrapes groundwater and surface water monitoring data from Wasserportal Berlin — station metadata, water levels, quality series. For its first four years that was the whole product, with releases tracking the portal's own churn: a new API version in 2023, new three-letter variable codes, and a 2026 fix decoding pages as windows-1252 because the server declares UTF-8 but emits Latin-1. In June 2026 it added a ThingsBoard integration, then extended it to self-hosted instances two days later.

The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.
◆ Current state
tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.
◆ Where it's heading
Two moves in nine days point at the same destination: the generics conversion made tulpa extensible by downstream packages, and CRAN admission makes it installable by them. The current cadence — several tags a week, some existing only to record a measurement that produced no code change — does not survive CRAN's submission overhead, so the release rhythm has to slow whether or not the project intends it. The correctness work still clusters on the joint nested-Laplace driver, and 0.1.0 extends the same diagnostics habit with .NL_AXIS_SD_REASONS, a closed vocabulary for an outer axis whose grid does not contain its own posterior mode.
◆ Prediction
Expect tulpaObs to follow tulpa onto CRAN, since it is the consumer whose registrations the engine has spent this window unblocking, and expect the version line to move in larger, less frequent steps now that each one carries a submission.
wasserportal
0.0ANALYTICS
A Berlin groundwater scraper grew a full IoT publishing pipeline in two days.
◆ Current state
wasserportal scrapes groundwater and surface water monitoring data from Wasserportal Berlin — station metadata, water levels, quality series. For its first four years that was the whole product, with releases tracking the portal's own churn: a new API version in 2023, new three-letter variable codes, and a 2026 fix decoding pages as windows-1252 because the server declares UTF-8 but emits Latin-1. In June 2026 it added a ThingsBoard integration, then extended it to self-hosted instances two days later.
◆ Where it's heading
The package is repositioning from a data-access library into the first half of a monitoring pipeline. 0.6.0 shipped push helpers, device discovery and cleanup, an importable dashboard and a GitHub Actions workflow; 0.7.0 immediately generalised the authentication so it works against self-hosted Community Edition rather than only the Cloud tier, and lifted the push from a five-station demo to the entire groundwater archive. The hardening detail in 0.7.0 — retries on 5xx, warnings when only one of two credentials is set — reads like a maintainer who has run this against a real deployment.
◆ Prediction
The obvious next step is extending the ThingsBoard path to the surface water stations, which the package has flagged as under-supported since 0.1.0. The entries show no other direction under construction.
