DESCRIPTION:What is an open source sprint?\n\nAn open source sprint is an 
 event where programmers come together to make focused contributions to an 
 open source project within a limited timeframe. Participants can work indi
 vidually or in groups\, collaborate directly on coding tasks\, fix bugs\, 
 and develop new features for the project. The sprint environment offers ha
 nds-on coding\, mentorship from experienced contributors\, and fosters net
 working and community building among peers. Through time-boxed sessions\, 
 programmers can learn from each other\, solve problems collaboratively\, a
 nd quickly advance project goals in a welcoming\, supportive setting.\n\n
 \nWhy should you join?\n\n- Gain practical coding experience on real-world
  projects\n- Receive guidance and mentorship from skilled contributors\n- 
 Make a meaningful impact on an open source project\n- Expand your professi
 onal network and meet like-minded peers\n- Learn best practices and new te
 chnologies in a supportive environment\n\nSpecifically: A hands-on sprint 
 for people who use Polars and want to go one layer deeper. Pick one of two
  tracks: work on a "good first issue" from the Polars issue tracker\, or b
 uild an expression plugin that adds your own custom functionality to Polar
 s\, running at native speed. You leave with either an open PR or a working
  plugin\, and a setup you can keep using afterwards.
