What is the polyglot infrastructure tax?

The maintenance burden when your CI supports 3 languages but your stack uses 11, forcing custom, rotting Docker images.

How do I fix Terraform validation in GitHub Actions?

Install mise on your runner, add a .tool-versions file pinning terraform, then `mise exec -- terraform validate`. No customs needed.

Will mise replace Docker in CI entirely?

Not replace – augment. Use it for runtimes; Docker for app packaging. Handles the polyglot pain without image bloat.

⚡ Key Takeaways

Polyglot teams waste hours on custom Docker for unsupported languages – the 'infrastructure tax' kills velocity. 𝕏
Tools like mise or Nix fetch pinned runtimes on-demand, slashing maintenance to zero. 𝕏
Demand per-language metrics in CI; without them, you're blind to the rot. 𝕏
