SigmaMind AI vs Vapi vs Retell: Data Privacy that Developers can trust
Developers shouldnโ€™t have to guess what happens to their conversations once they hit the platform. With Vapi and Retell, โ€œownershipโ€ often comes with strings attached. SigmaMind AI takes the opposite stance: your data is fully yours, and nothing is used for training without your consent.

  • Concurrency in Haskell: Fast, Simple, Correct
    I'm not going to sell you on anything. All of the things you've mentioned are true. Loosely, the multitude of string types and the state of the standard library come from the same place: the language is 30+ years old! There are many warts to be found. However, if you decide to start learning, the path is hard, especially if you come from a non-computer-science background like me.

  • Ask HN: What resources do you recommend for learning Haskell?
    Haskell Programming from First Principles[1] is extremely comprehensive, covering everything from lambda calculus to IO. For further self-learning, it might be interesting to learn about the underlying mathematical concepts, such as category theory. A deep dive into the workings of a Hindleyโ€“Milner type system might also significantly demystify some of Haskell's typing magic.

  • Ask HN: What resources do you recommend for learning Haskell?
    I really liked https://haskellbook.com/. Itโ€™s long, but has exercises after each chapter which I found very helpful. The first chapter is about Lambda Calculus which is kind of a meme at this point, but learning it actually did help me a lot to grok how Haskell programs are meant to fit together. Other than that, just doing some basic side projects and leaning about how to use Cabal effectively should get you there. - Source: Hacker News / almost 2 years ago
  • Ask HN (Personal): Has anyone here ever tried throwing everything away?
    Yeah! Six months after graduating from Northwestern University I quit my cushy 6-figure WFH job to move to Finland as a quasi-illegal immigrant. (I say "quasi-" because "STEM undergrad from a top university moving to a much poorer country" is, ah, not what you usually think of.) I was unemployed for over a year due to passport issues, living in a tiny vacation town of ~10,000 close to the Arctic Circle, and used... - Source: Hacker News / over 2 years ago
