An explorer's log is a personal blog at nakkaya.com about programming. Since 2009, 40 different Hacker News readers have linked it 58 times, most often “Ferret: A Hard Real-Time Clojure for Lisp Machines”. The last post was in 2017, but the archive is still widely read.
Too few sampled comments (12) to say how often HN recommends it.?
Why HN links it
Nurullah Akkaya's blog posts on Clojure and Lisp, including Ferret, a Clojure subset compiled to C++, Java native access and minimal Lisp implementations. HN commenters link them as technical references.
Summarised by Claude from a sample of 12 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
One of my favorite resources is the #clojure tag on Twitter. I use Tweetie and have bookmarked a search on that. Here are a few sites from my GReader http://www.bestinclass.dk/blog.html http://nakkaya.com/ http://freegeek.in/blog/ https://groups.google.com/group/clojure And here are a few tabs that I currently have open (Maybe this weekend I will get to them :D) https://github.com/dbushenko/ClojureBlog http://skills…

HN discussionFerret is another Clojure implementation in C, that has a decent C/C++ interface: https://nakkaya.com/2017/06/24/ferret-lisp-ffi-notes/ I'm curious if the author of jank was aware of Ferret, and what was found lacking.

HN discussionAuthor here. Did not knew about Céu till now, just watched the intro video. I maintain a behaviour tree [1] library called alter-ego [2] (code needs cleanup) which already contains some of the constructs. In behaviour tree terms par/or is parallel selector and watching is a interrupter node. [3] So it can be done in Ferret on a general purpose PC using C++11 concurrency constructs, for embedded targets it will requi…

HN discussionI'm not sure how it's implemented in Ferret but Clojure's data structures are implemented as trees so there's structural sharing that happens when a vector or hash map is updated or when a new version is produced. So the whole data structure isn't copied but only the relevant parts are added / updated in the tree and the rest is shared with the "new" data structure. Mutable data structures are still more memory effe…

HN discussionI maintain a programming language called Ferret [1]. You can read through the manual, it is a literate program, covers everything you need to implement your own lisp. Compiler, optimizations, runtime, garbage collection etc. [2] overlaps with [1] covers how to compile a restricted subset of Clojure to C++. If you are interested in interpreters [3] has an implementation of the "A Micro-Manual for Lisp - not the whole…

HN discussionIt is possible. Some scheme compilers use C as their intermediate language. Scheme to C to binary. (Gambit/Chicken/Stalin etc.). I have a project [1][2] that compiles a subset of Clojure to C++11 that is written using literate programming [3]. It thoroughly documented and should give you an idea on how to build your own.
