Haskell From First Principles mentions (87)

• 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. I attempted to learn Haskell... - Source: Hacker News / over 1 year ago

• Functional Programming Self-Affirmations

  I'm a big fan of Haskell Programming from First Principles. That's where more advanced ideas like Monads started clicking. https://haskellbook.com/. - Source: Hacker News / over 1 year ago

• 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 Hindley–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/. It’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 / about 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

• Stop Judging Every Run: Eval Sampling Is a Budget Decision, Not a Coverage One

  This is why eval and observability ship as a unit, not as separate purchases. agent-eval scores and gates the output — the tiers above, drift, hallucination. AgentLens captures the trace of how the agent got there: every model step and tool call, the resolved inputs, the raw outputs, the trajectory. Two things fall out of that:. - Source: dev.to / 4 days ago

• Claude Code permission rules: how allow, deny, and ask actually match

  The real fragility is in trying to constrain arguments. The docs are explicit that a pattern like Bash(curl http://github.com/ *) fails to do what it looks like it does. It won't match curl -X GET http://github.com/... (option before the URL), curl https://github.com/... (different protocol), curl -L http://bit.ly/xyz (redirects to GitHub), URL=http://github.com && curl $URL (variable), or curl http://github.com... - Source: dev.to / 5 days ago

• 3 ways to add link previews to a React app (with and without a backend)

  Fallback chains — og:title → twitter:title →

  SSRF protection — if you fetch user-supplied URLs, you MUST block localhost, RFC-1918 ranges, and internal hostnames, or your preview endpoint is a proxy into your own infrastructure

  Caching — you do not want to re-fetch a URL on every render

  Rate limiting — a public...
