Programming competition.

If you have Andrew, Deyuan or Dion in your class, be sure to congratulate them! Yesterday they have won the ICPC Greater NY programming competition:

Overall, this is probably the best results that Yale had at the regional level: we are the champions and we have three teams in the top 10 teams, which makes Yale the best positioned school this year, of all school competing in the Greater New York area (NYU, Princeton, Cornell, Columbia...). All together 76 teams participated.

Monday's guest speakers were Joanne Lipman, a graduate of Yale and a lecturer at Yale, and her daughter, Rebecca Distler who is a graduate of Yale College and the School of Public Health, and the co-author of the linked Time Magazine article: "Schools Shouldn't Ban Access to ChatGPT" (January 11, 2023). I will be posting their contact information.

Trading Competition

From Kaitlyn Sandler, a former CS 458 student:

The company I am working for next year is hosting a super cool trading challenge in March. No trading or CS experience required!
Info:
IMC Trading is hosting a global, 10-day trading challenge called Prosperity! Put your analytical and technical skills to the test in a virtual market. Go head-to-head against thousands of like-minded people from all over the world by trading items like wasabi roots, pineapples and pizza with savvy penguins and forgetful ducks.
Prize: The winner receives $25,000! IMC will also donate another $25,000 in your name to global nonprofit, The Ocean Cleanup.
Registration Link: https://prosperity.imc.com/?utm_source=referral-contest&utm_medium=kaitlyn-sandor&utm_campaign=prosperity_2023
The challenge starts on March 20th (the tail end of break) and runs until March 30th with 5x 48hr rounds. The basic premise is you are on an island and need to trade with surrounding islands to allow your island to prosper the most. You can implement both automated and manual trading and there is some helpful advice in the wiki on resources to start if students aren't sure exactly how to implement a trading algorithm: https://imc-prosperity.notion.site/Writing-an-Algorithm-in-Python-c44b46f32941430fa1eccb6ff054be26
There is also this promo video of the challenge: https://www.youtube.com/watch?v=XSiyC6erX8E&embeds_euri=https%3A%2F%2Fprosperity.imc.com%2F&source_ve_path=Mjg2NjQ&feature=emb_imp_woyt
