What is Cursor?
Cursor now hosts the code its agents work on.
Cursor has spent two months moving agents out of the editor: cloud agents on iPhone and iPad, in Slack, and on schedules; a team marketplace distributing plugins and MCP servers; a router picking the model per request. Origin adds the last missing layer by hosting repos and pull requests inside Cursor itself. Everything from prompt to merge can now happen without leaving the product.
What is simDAG?
simDAG grew a second simulation engine, then spent two releases surviving upstream breakage.
simDAG generates data from directed acyclic graphs, with a library of node types covering Gaussian, binomial, Poisson, negative binomial, zero-inflated, ordered regression, Cox, and Aalen models. The 1.0.0 milestone opened node_cox() to arbitrary baseline hazard functions, which lets continuous time-dependent hazards drive discrete-event simulations. The two most recent releases exist only to keep the package on CRAN through breakage in lme4 and simr.
Cursor vs simDAG: editorial side-by-side
Cursor
7.5INFRA · APIS
Cursor now hosts the code its agents work on.
◆ Current state
Cursor has spent two months moving agents out of the editor: cloud agents on iPhone and iPad, in Slack, and on schedules; a team marketplace distributing plugins and MCP servers; a router picking the model per request. Origin adds the last missing layer by hosting repos and pull requests inside Cursor itself. Everything from prompt to merge can now happen without leaving the product.
◆ Where it's heading
Each release removes an external dependency or a wait state. Builds keep environments warm so agents skip setup, Cursor Router removes the model-picking decision, and Origin removes the trip to GitHub for browsing, review, and merge. The app tab on Origin repos - Vercel previews, Depot and Buildkite CI - shows Cursor recruiting the vendors that currently attach to GitHub Actions.
◆ Prediction
Cursor said agent-native features for Origin ship soon; expect agents that open, review, and merge pull requests against hosted repos without a human starting each one, plus more app-tab integrations along the Vercel/Depot/Buildkite pattern.
simDAG
2.5INFRA · APIS
simDAG grew a second simulation engine, then spent two releases surviving upstream breakage.
◆ Current state
simDAG generates data from directed acyclic graphs, with a library of node types covering Gaussian, binomial, Poisson, negative binomial, zero-inflated, ordered regression, Cox, and Aalen models. The 1.0.0 milestone opened node_cox() to arbitrary baseline hazard functions, which lets continuous time-dependent hazards drive discrete-event simulations. The two most recent releases exist only to keep the package on CRAN through breakage in lme4 and simr.
◆ Where it's heading
The package has been widening what a simulation can represent rather than deepening any one node. Networks arrived in 0.4.0 so individuals could depend on each other, discrete-event simulation in continuous time arrived in 0.5.0 as an alternative to the discrete-time engine, and 1.0.0 connected the two by letting continuous hazards feed the event-driven path. Alongside that, node types keep accumulating for outcome families the framework could not previously generate.
◆ Prediction
Expect the node library to keep expanding into outcome types the discrete-event engine can now support, though the recent releases suggest upstream dependency churn will keep consuming release slots.
