podsnap is a personal blog at blog.podsnap.com about programming. Since 2013, 16 different Hacker News readers have linked it 25 times, most often “Type-safe Transducers in Clojure, Scala, and Haskell”. It is still writing: the last post was on 2026-01-31, and you can follow it by feed.
Too few sampled comments (4) to say how often HN recommends it.?
Why HN links it
HN readers link podsnap for Clojure and functional programming posts, including a detailed look at transducers in Clojure, Scala and Haskell, a bitemporal data post, and a van Laarhoven lens implementation in typed Clojure.
Summarised by Claude from a sample of 4 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
This issue was discussed in the Datomic google group back in 2012. I think a satisfying solution was found in the end. https://groups.google.com/forum/#!topic/datomic/zDoFsxKgARQ . Also, there's this blog post: http://blog.podsnap.com/bitemp.html

HN discussionI emphatically reject the many of the conclusions of this article. >Let me say it simply. Type systems cannot be a one-stop solution for specification and verification. Wrong! Any correctness property can be encoded into a sufficiently powerful type system. Which brings me to... >Curry-Howard is an interesting mathematical equivalence, but it does not advance any argument about how to write software effectively. Thi…

HN discussionHere's another video by Rick Hickey about transducers: https://www.youtube.com/watch?v=6mTbuzafcII - it was referenced in this great post detailing the transducer notion with Clojure, Scala, and Haskell: http://blog.podsnap.com/ducers2.html

HN discussionOk, I managed to get a van Laarhoven representation in typed Clojure, though it wasn't exactly a smooth experience. http://blog.podsnap.com/vanhole.html
