What is exametrika?

A test-theory package that grew into a graphical-model toolkit, now spending its releases paying down the API debt that growth created.

exametrika is an R psychometrics package covering IRT, latent class/rank analysis, and biclustering, and it has been shipping features at an unusual clip for a CRAN package. The last two releases stopped adding capability and turned inward: 1.14.0 fixed a documented-but-never-implemented graphical-parameter passthrough, and 1.15.0 landed a full-codebase audit that corrected bugs which silently produced wrong results on missing data and 0-indexed polytomous codes. Argument names, orders, and defaults are now unified across the model functions, with every old name kept working behind a deprecation warning.

What is Scrypted?

Scrypted spent a year making its camera server run as a cluster, then went quiet.

Scrypted publishes releases as raw commit dumps, so the arc has to be read from the commits themselves. Through 2025 they cluster around three things: cluster mode and the worker addressing needed to make it real, GPU inference plumbing for NVIDIA on Proxmox and Intel runtimes, and a steady stream of per-camera fixes for battery, sleeping, and NVR devices. The most recent tag in this feed is from November 2025, so the visible record stops there rather than continuing to the present.

A test-theory package that grew into a graphical-model toolkit, now spending its releases paying down the API debt that growth created.

◆ Current state

exametrika is an R psychometrics package covering IRT, latent class/rank analysis, and biclustering, and it has been shipping features at an unusual clip for a CRAN package. The last two releases stopped adding capability and turned inward: 1.14.0 fixed a documented-but-never-implemented graphical-parameter passthrough, and 1.15.0 landed a full-codebase audit that corrected bugs which silently produced wrong results on missing data and 0-indexed polytomous codes. Argument names, orders, and defaults are now unified across the model functions, with every old name kept working behind a deprecation warning.

◆ Where it's heading

The arc runs from feature sprawl to consolidation. Through 1.9.0-1.13.0 the package added polytomous biclustering plots, nominal and ordinal IRM samplers, a C++ Gibbs core, and Graphical Lasso; the cost was inconsistent interfaces and correctness bugs that only surfaced under audit. The maintainer is also visibly optimizing for two external gatekeepers — CRAN's 10-minute check budget in 1.13.1, an R Journal reviewer in 1.14.0 — which suggests the package is being groomed for formal publication rather than just iterated on.

◆ Prediction

Expect the next release to continue the deprecation cleanup started in 1.15.0, likely retiring some of the old function names that have carried warnings since 1.7.0, with new modelling work paused until the R Journal submission clears.

Scrypted spent a year making its camera server run as a cluster, then went quiet.

◆ Current state

Scrypted publishes releases as raw commit dumps, so the arc has to be read from the commits themselves. Through 2025 they cluster around three things: cluster mode and the worker addressing needed to make it real, GPU inference plumbing for NVIDIA on Proxmox and Intel runtimes, and a steady stream of per-camera fixes for battery, sleeping, and NVR devices. The most recent tag in this feed is from November 2025, so the visible record stops there rather than continuing to the present.

◆ Where it's heading

The direction through the tracked window is a home camera server growing into distributed infrastructure: cluster mode, cluster-aware media management, worker addressing, and detection work moving onto custom models and fp16 math. Integration breadth continues alongside it, with HomeKit audio, ONVIF PTZ, text overlays, and PIR sensors. Because the feed has not produced a tag in months, any read on current direction should be treated as the state at the last release rather than today.

◆ Prediction

The entries do not support a confident prediction; the feed has been silent since November 2025, and a stale release stream is not evidence of what the project is doing now.
