HN discussionClojure as well, e.g.: http://blog.cognitect.com/blog/2015/6/30/walmart-runs-clojur... They're pretty language agnostic from what I've heard, not always in a good way.

HN discussionI thought that was strange survey at first, as there were very few questions related to programming and coding with Rust but plenty of questions around engaging with the community (inclusiveness/comfort level, conference attendance, etc). But then I realized it was a "Rust Community Survey". Is there another survey more suited to use Rust as a language ala "State of Clojure"? I don't use Clojure anymore but I still…

HN discussionSo this is a common issue on the clojure sub-reddit the two good responses i've seen to this is the library expound ( https://github.com/bhb/expound ) so you get more 'human' read-able errors and my personal favourite is Stuart Hallows blog post REPL DEBUGGING: NO STACKTRACE REQUIRED ( http://blog.cognitect.com/blog/2017/6/5/repl-debugging-no-st... )

HN discussionIf you can, I'd suggest use spec to improve your understanding and verify behavior. I certainly do know that Clojure can get very dense if you're not careful. http://blog.cognitect.com/blog/2017/6/19/improving-on-types-...

HN discussionTom, have you heard of EDN and Transit? Like JSON, but: 1. Extensible, custom types 2. Streamy, efficient, compressed and fast, leverages platform's existing native/optimized JSON parsers 3. Wide platform reach 4. Made by Rich Hickey http://blog.cognitect.com/blog/2014/7/22/transit

HN discussionWhere does Clojure fit in the technology stack of Walmart? Cognitect has a few references that seem a bit old [1], but I see WalmartLabs release clj libraries from time to time [2], and I heard a podcast once where someone talked about working with Clojure remotely too [3]. 1: https://www.cognitect.com/walmart-case-study.html 2: https://github.com/walmartlabs/lacinia 3: http://blog.cognitect.com/cognicast/087

HN discussionThat's not a very plain-language description of transducers. Transducers are functions which can be applied to any sort of collection or sequence. You can use then to do something like filter a collection or an input stream with the same code. They are basically just a way to make things like 'map' and 'filter' work on datatypes other than sequences, such as streams or channels. http://blog.cognitect.com/blog/2014/8…
