What is serofoi?

serofoi grew a serosurvey simulator alongside the force-of-infection models it was built to fit.

serofoi estimates the force of infection from serological survey data using Bayesian serocatalytic models fitted through Stan. Beyond fitting it now simulates serosurveys — specifying a model and a survey design and generating the data such a survey would produce. The most recent release is visualisation and naming work.

What is Rho?

Rho's release machinery finally produced a stable build — and it shipped no new product.

Rho is an R IDE that has just moved from an all-prerelease train to a stable 0.4.0, and its public feed remains almost entirely release engineering. The one substantive entry, 0.4.0-dev.39, described capability-based model routing across providers and durable project-scoped agent conversations with per-file Apply/Undo. The releases since then have been distribution work: a signed automatic updater shared across Windows, macOS and Linux, then the stable build that packages it.

serofoi grew a serosurvey simulator alongside the force-of-infection models it was built to fit.

◆ Current state

serofoi estimates the force of infection from serological survey data using Bayesian serocatalytic models fitted through Stan. Beyond fitting it now simulates serosurveys — specifying a model and a survey design and generating the data such a survey would produce. The most recent release is visualisation and naming work.

◆ Where it's heading

The package moved from fitting-only to a fit-and-simulate pair. 0.1.0 added simulation from time- or age-varying force-of-infection trends and simplified the fitted object down to a Stan fit; 1.0.2 broadened simulation into full serosurvey generation with its own vignette. 1.0.3 then spent its effort on naming consistency and plotting options, which is what a package does once its scope is set.

◆ Prediction

With simulation and fitting both in place, the natural next step is tooling that closes the loop between them — recovery checks or study-design guidance built on simulated surveys.

Rho's release machinery finally produced a stable build — and it shipped no new product.

◆ Current state

Rho is an R IDE that has just moved from an all-prerelease train to a stable 0.4.0, and its public feed remains almost entirely release engineering. The one substantive entry, 0.4.0-dev.39, described capability-based model routing across providers and durable project-scoped agent conversations with per-file Apply/Undo. The releases since then have been distribution work: a signed automatic updater shared across Windows, macOS and Linux, then the stable build that packages it.

◆ Where it's heading

The project is building an agentic R IDE but publishing like a regulated release process: signed evidence, checksums bound to exact commits, and limitations named out loud rather than buried. That discipline has now paid off in the only way it could — 0.4.0 stable ships a Windows installer, a notarized macOS disk image and a Linux AppImage that can all update themselves, with failed verification preserving the running version. The feed's long-standing pattern of dev.NN builds with no final has broken; feature work and shipping work were on separate tracks, and the shipping track arrived first.

◆ Prediction

With distribution solved, the next entry that matters is the first one describing product capability again rather than packaging. The unresolved item these releases name themselves is Windows trust: the installer is still signed with a SignPath Free Trial self-signed certificate that SmartScreen may warn on.
