What is RNifti?
The C++ layer under R's neuroimaging stack, closing the gaps where images stopped acting like arrays
RNifti reads and writes NIfTI and ANALYZE medical image files, exposing them to R through an internalImage class that keeps pixel data on the C++ side until it is needed. It is infrastructure: other neuroimaging packages depend on it, and much of its release history is driven by their bug reports. Recent work has been about making that lazy image type behave like a normal R array without giving up the memory advantage.
What is WorkOS?
WorkOS is building identity for agents while quietly fixing the sign-up funnel.
WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.

The C++ layer under R's neuroimaging stack, closing the gaps where images stopped acting like arrays
◆ Current state
RNifti reads and writes NIfTI and ANALYZE medical image files, exposing them to R through an internalImage class that keeps pixel data on the C++ side until it is needed. It is infrastructure: other neuroimaging packages depend on it, and much of its release history is driven by their bug reports. Recent work has been about making that lazy image type behave like a normal R array without giving up the memory advantage.
◆ Where it's heading
Two threads run through these releases. One extends what the package can represent — RGB arrays, complex datatypes, JSON sidecar metadata — steadily widening the file and type surface it covers. The other closes semantic holes in the deferred-loading design, where R would silently fall back on character methods because the image class had no method of its own. The 1.9.0 work is the clearest example, and it is careful to keep the memory benefit by pushing summaries into C++ rather than materialising an array.
◆ Prediction
The JSON sidecar support is flagged as R-only for now, which makes exposing it through the C++ API the most likely next step.

WorkOS is building identity for agents while quietly fixing the sign-up funnel.
◆ Current state
WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.
◆ Where it's heading
The agent work is the strategic line. Registration gives an agent an identity of its own instead of a borrowed human session; the token proxy means an application acting for a user never holds the credential. Together they describe a stack where an agent can be authorized, audited and revoked as a first-class principal. The human-auth releases are conversion and migration work — the deliverability check and SCIM Bridge both remove reasons a customer stalls — which is what a developer-infrastructure company does while its next category is still forming.
◆ Prediction
Registration and the token proxy leave scoping and revocation as the visible gaps, so expect per-agent permissions or consent surfaces next. Whether auth.md gains adoption beyond WorkOS is not something these entries can answer.
