2026-01-27 20:20:51 <lambdabot> [3,5,3,1]
2026-01-27 20:25:27 <monochrom> Yeah what int-e said. In that example, the root has 3 children, map leavesByDepth (those 3 chidlren) = [[1], [1,3,3,1], [1,2]]. So you want to turn that into [1+1+1, 3+2, 3, 1].
2026-01-27 20:25:41 <dutchie> ah transpose

2026-01-27 22:45:07 <Guest41> hello!
2026-01-27 22:45:50 <Guest41> Does anyone else find haskell  hard to learn using chatgpt, I can get working code of cute snippets and programs but I feel like if OpenAI went bankrupt I would be useless lol, or would take forever to type down
2026-01-27 22:46:06 × EvanR quits (~EvanR@user/evanr) (Remote host closed the connection)
2026-01-27 22:46:42 <ski> how about learning from a textbook ?
2026-01-27 22:47:18 <ski> or, perhaps, a course, like
2026-01-27 22:47:22 <ski> @where CIS194
2026-01-27 22:47:22 <lambdabot> <https://github.com/byorgey/haskell-course>,<https://www.seas.upenn.edu/~cis194/spring13/lectures.html>
2026-01-27 22:47:31 <Guest41> I have this one : Introduction to Computation: Haskell, Logic and Automata
2026-01-27 22:47:43 <Guest41> but maybe I should go along it with the course as well :-)
2026-01-27 22:47:47 ski wouldn't learn anything using an LLM chatbot
2026-01-27 22:48:36 <tomsmeding> (you don't know yet which of its output is useful and which is not)
2026-01-27 22:48:48 <ski> when you're learning something, you don't want to deal with the risk of hallucinations
2026-01-27 22:49:19 <ski> when you know more about an area, you can (more) tell what is nonsense, and what isn't
2026-01-27 22:49:28 <ski> when you're just learning, you can't
2026-01-27 22:49:30 <Guest41> been programming for a long long while in C,C++,python,verilog,etc. so I can "kind of" tell when it's lying
2026-01-27 22:49:52 <Guest41> but you're right I can't just google all the output and hope to double check everything, the small hallucination risk sucks there
2026-01-27 22:49:55 mange joins (~mange@user/mange)
2026-01-27 22:50:48 <Guest41> Huh actually <https://www.inf.ed.ac.uk/teaching/courses/inf1/fp/> is the course for the textbook I do have, hooray!
