Four house rules

  1. 01Run it first
    We only write about what we have actually run on our own machines or VPSes. No press-release rewrites.
  2. 02Keep the commands
    Steps, config files, even the failing logs — enough for you to reproduce it.
  3. 03Date everything
    Prices and specs drift. Every claim carries the day we checked it.
  4. 04Show the money
    Affiliate links are marked. Tools that pay us nothing still get recommended when they are good.
