Last.fm's 200-line C library that every memcached client copies. MD5 → 4 hash positions per virtual node → 160 vnodes per host. Read the algorithm end to end.

The overview above is ready. The full-fledged deep dive with explanations, code walkthroughs, and animated diagrams is queued for the next authoring pass.

Meanwhile, return to the main consistent hashing page for the full concept explanation including animated walkthroughs and real-world scenario visualizations.
