We’re going to detect balls, referees, players, and goalkeepers in soccer matches using Ultralytics’ fine-tuning tools.

Elixir HTTP caching libraries have been updated to version 0.4.0 with support for the “stale” cache control directives. These two directives are additional directives added by RFC5861 - HTTP Cache-Control Extensions for Stale Content. They allow serving stale content in particular cases. Content is considered stale when its caching time limit has expired. For instance, using the max-age response header: cache-control: max-age=60 this page will be considered stale in 1 minute and no longer...| Tangui's blog

Elixir provides MapSet module to handle sets—lists of unique elements (shall I say “arrays” instead of lists here?). They are very handy under many circumstances.
