What is BayLum?

Bayesian luminescence dating that finally replaced its folder-structure input format.

BayLum runs Bayesian age models for luminescence and combined OSL/C-14 dating on top of JAGS. The 2024 release rebuilt the front end: a single create_DataFile() replaces the separate single-grain and multi-grain generators, reads BIN/BINX and XSYG directly, and takes a YAML config in place of the old prescribed folder layout. Since then the work has been CRAN compliance and documentation.

What is Buildkite?

Buildkite is rebuilding CI as something agents drive, not just humans.

Buildkite's recent releases split in two: MCP tooling for agents - list_tests, wait_for_build, compliance with the stateless MCP spec - and broader REST/GraphQL coverage so setup, governance, and troubleshooting can run headless. Conventional CI work continues underneath, with checkout configuration in pipeline YAML and OpenTelemetry job log export. The framing on nearly every note is what an agent can now do without a human in the loop.

Bayesian luminescence dating that finally replaced its folder-structure input format.

◆ Current state

BayLum runs Bayesian age models for luminescence and combined OSL/C-14 dating on top of JAGS. The 2024 release rebuilt the front end: a single create_DataFile() replaces the separate single-grain and multi-grain generators, reads BIN/BINX and XSYG directly, and takes a YAML config in place of the old prescribed folder layout. Since then the work has been CRAN compliance and documentation.

◆ Where it's heading

Two long-running threads have converged: making JAGS runs survivable (parallel methods, halved MCMC memory, injectable custom models) and making the inputs survivable (YAML config, consistency checks, auto-detected sample names). With the deprecated generators on their way out, the next phase is removal rather than addition. Release cadence is roughly annual and slowing.

◆ Prediction

The deprecated Generate_DataFile(), Generate_DataFile_MG() and LT_RegenDose() are the obvious next casualties; a release that drops them would be the first breaking change since the YAML rework.

Buildkite is rebuilding CI as something agents drive, not just humans.

◆ Current state

Buildkite's recent releases split in two: MCP tooling for agents - list_tests, wait_for_build, compliance with the stateless MCP spec - and broader REST/GraphQL coverage so setup, governance, and troubleshooting can run headless. Conventional CI work continues underneath, with checkout configuration in pipeline YAML and OpenTelemetry job log export. The framing on nearly every note is what an agent can now do without a human in the loop.

◆ Where it's heading

Buildkite is arguing that CI should be forge-independent, and it is now backing that with coverage: GitHub, GitLab, Bitbucket, and as of this week Cursor's Origin, where it shipped as a launch partner on day one. On the agent side the pattern is removing the workarounds automation used to need - a wait tool instead of a polling loop, aggregated test metrics instead of assembling individual runs, an early failure signal instead of waiting for a job to exit. Each release converts a hand-rolled agent behavior into a first-class primitive.

◆ Prediction

The read side of the MCP server is now largely covered, so expect write-side tools next - retrying jobs, unblocking builds, creating or editing pipelines from an agent - following the same pattern the REST expansion just established.
