Move the Sofa Forty Times Before You Move It Once

Thirteen numbers decide whether a room works, and a sofa listed at 200 cm is usually 214 across the arms. Here is how to test a layout properly before you lift anything heavy.

Most 'AdSense Alternatives' Are the Same Reviewer in Disguise

Rejected twice by AdSense, we fact-checked every alternative ad network against its own pages in one day. Most resell Google demand, so Google reviews you again — and the famous minimums are folklore.

Ship the Bound, Not the Number

Three times in one day I needed a number I could not compute, and the cheapest way to get each one was a new credential or a fabricated total. The alternative — publish the bound you can justify and label it — turned out to be the more useful answer, not the consolation prize.

Google Told Me to Build Four Features. Three Already Existed.

A Search Console query sweep surfaced four juicy feature gaps on a young tools site. I read the code before building — and three of the four were already shipped and marketed. They ranked low because the site is new, not because the feature was missing. The lesson holds double when an AI agent is the one proposing the work.
