Coldwast
Programming & dev guides, kept up to date.
Coldwast is an independent collection of original programming references — clear, technically honest, and revised as toolchains move. It starts where this domain has deep roots: the Haskell / Cabal build toolchain. From there it expands into the wider developer stack — build performance, deployment, and the tools real projects ship on.
Featured guides
- Cabal Sandboxes — and what replaced them Haskell · updated 2026
The per-project isolation idea that won so completely it became invisible. What sandboxes were, and the nix-style
cabal buildworkflow that superseded them. - Cabal 2.0 — the release that reshaped Haskell builds Haskell · updated 2026
Nix-style builds, Backpack, the caret operator — what 2.0 introduced and where each feature stands today.
- Parallelising cabal-install Haskell · updated 2026
Why a build is a dependency graph, how
-jbuilds use your cores, and the modern job-semaphore fix for oversubscription.
coldwa.st is now an independent programming-resources site. Its Haskell/Cabal guides are original, community-maintained rewrites updated for the current toolchain — not authored by or affiliated with the domain's previous owner. See the editorial policy.
