The solver takes the LLB graph and executes it. Each vertex in the DAG is content-addressed, so if you’ve already built a particular step with the same inputs, BuildKit skips it entirely. This is why BuildKit is fast: it doesn’t just cache layers linearly like the old Docker builder. It caches at the operation level across the entire graph, and it can execute independent branches in parallel.

The entire SEO industry built around understanding and exploiting that single funnel.
In the vacuum of space, the amount of debris—spent rocket stages, splintered satellites, micrometeoroids—numbers in the millions, all zooming about, often at 17,000 mph speeds. They’re also constantly hitting each other in a tsuris of exponential littering. Most of these pieces are tiny, and many are not anywhere near the altitude of the ISS. But the area isn’t completely clean.
