What is rgm?

A microbiome network model that got itself un-archived by deleting the dependency that killed it.

rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.

What is RSS-Bridge?

The web's duct-tape RSS layer, now quiet for a year after flipping every bridge on by default.

RSS-Bridge generates feeds for sites that removed theirs, and each release is a batch of community fixes to individual bridges plus a handful of new ones. Releases are date-tagged rather than versioned and land every few months, with the most recent in August 2025 — roughly a year of silence since. The core is stable PHP; the churn is in the ~400 site-specific scrapers that break whenever a target site changes markup or adds bot protection.

◆ Current state

rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.

◆ Where it's heading

Three tags shipped inside two hours on one day, and the notes are candid about why: 1.1.0 held the actual work but was never released, 1.2.0 restated it under a higher version to signal the size of the change, and 1.2.1 answered CRAN pre-test feedback. Beyond the archival recovery, the visible work is housekeeping that had accumulated — a shadowed rmvnorm() definition, roxygen import tags that were silently emitting nothing, leftover C++ template scaffolding, and build artifacts under version control. The diagnostics function is the only genuinely new user-facing capability in the window.

◆ Prediction

The immediate task was restoring availability, and that is done; the open question the entries raise is whether losing the graphical-lasso warm start affects convergence in practice, which the new diagnostic plots are positioned to answer.

0.0

The web's duct-tape RSS layer, now quiet for a year after flipping every bridge on by default.

◆ Current state

RSS-Bridge generates feeds for sites that removed theirs, and each release is a batch of community fixes to individual bridges plus a handful of new ones. Releases are date-tagged rather than versioned and land every few months, with the most recent in August 2025 — roughly a year of silence since. The core is stable PHP; the churn is in the ~400 site-specific scrapers that break whenever a target site changes markup or adds bot protection.

◆ Where it's heading

The project has been shifting from a curated tool to a general-purpose scraping surface: bridges are now all enabled by default, caching was rewritten, and token-based URL auth was added to make public instances survivable. That combination points at operators running shared instances rather than individuals running one bridge. The maintenance load, however, is entirely community-carried, and the gap since the last release suggests that pipeline has thinned.

◆ Prediction

The next release is likely another routine batch of bridge repairs and additions rather than a core change. The stated intentions in these notes — raising the minimum PHP version and separating the document root from the data folder — remain unshipped, and nothing here indicates when that lands.
