What is cbcTools?

Two years quiet, then a release that makes its greedy design methods practical

cbcTools generates and evaluates designs for choice-based conjoint experiments, gathering several strategies behind one method argument in cbc_design(): random, orthogonal via DoE.base, D-optimal, Bayesian D-efficient and greedy. That structure was set during 2023 across 0.4.0 and 0.5.0, which introduced the method argument, added strategies and documented in a table which options each one supports. The only release since, in August 2025, removes efficiency limitations from the greedy methods.

What is Warp?

Warp turned its quarter of software-factory essays into infrastructure you can buy.

Warp Factories arrives as open, flexible infrastructure for companies building internal cloud software factories — the productization of a content series that has run all quarter through triage, spec-driven development, self-improving code review, and computer-use verification. Two weeks earlier the Warp Agent became a standalone CLI running in Ghostty, iTerm2, VS Code, and the stock Windows and macOS terminals. The Factories entry itself is a single sentence, so what actually ships inside it cannot be read from this feed.

Two years quiet, then a release that makes its greedy design methods practical

◆ Current state

cbcTools generates and evaluates designs for choice-based conjoint experiments, gathering several strategies behind one method argument in cbc_design(): random, orthogonal via DoE.base, D-optimal, Bayesian D-efficient and greedy. That structure was set during 2023 across 0.4.0 and 0.5.0, which introduced the method argument, added strategies and documented in a table which options each one supports. The only release since, in August 2025, removes efficiency limitations from the greedy methods.

◆ Where it's heading

The package was explicitly built for extension — the 0.4.0 notes say the function is now better set up to add methods in future — and the pattern since has been adding or repairing one method at a time behind a stable interface. After a two-year gap the recent work is performance rather than coverage, which suggests the greedy methods were slow enough to be impractical at realistic design sizes. Restrictions have been added deliberately too, such as blocking the label argument for orthogonal designs because it would destroy orthogonality.

◆ Prediction

On the extension pattern the maintainer set up, the next release most likely adds another design method or continues tuning existing ones for speed; the entries do not indicate which.

Warp turned its quarter of software-factory essays into infrastructure you can buy.

◆ Current state

Warp Factories arrives as open, flexible infrastructure for companies building internal cloud software factories — the productization of a content series that has run all quarter through triage, spec-driven development, self-improving code review, and computer-use verification. Two weeks earlier the Warp Agent became a standalone CLI running in Ghostty, iTerm2, VS Code, and the stock Windows and macOS terminals. The Factories entry itself is a single sentence, so what actually ships inside it cannot be read from this feed.

◆ Where it's heading

The sequence is deliberate: publish the argument that agents belong off individual desktops, publish a build guide for the loop, unbundle the agent from the terminal so it can run anywhere, then sell the infrastructure that loop runs on. Warp has moved from a terminal company to an agent company to an infrastructure company across roughly one quarter, and the essays functioned as the roadmap the whole time. What remains unclear is packaging — Factories is described as open and flexible without saying what is hosted, what is self-run, or what is paid.

◆ Prediction

Expect Factories to be documented in the same instructional format as the build guide, with the existing skills — triage, review, verification — presented as components of it. Pricing and hosting model are the details most likely to arrive next, since neither is stated anywhere in these entries.
