It's always a fun day for the space nerds when a NASA team has new images to share from the James Webb Space Telescope. Today's pair has brains on the brain, with a look at the fittingly named Exposed Cranium Nebula. More officially, this cloud of space dust and debris is known as Nebula PMR 1.

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.
