Question 3

I am planning to improve my knowledge of Clojure and algorithms at the same time by implementing some known data structures in Clojure (e.g. linked lists, skip lists, bloom filter, etc.). However, I ...

Question 7

This older question tells us that in functional programming "true" randomness cannot be achieved since in FP functions are pure/idempotent and return the same value irrespective of number of ...

Question 8

I am designing a library to wrap an API with Clojure. The API requires user credentials to authenticate user related calls. My first approach was to have functions that do each task the API can do: (...

Question 9

I am designing a DSL (in clojure, specifically; though this question is more general than that) in which 'entities' are tracked as immutable hashes/maps, and where the 'concept' membership of an ...

Question 10

I was reading the post A Modern Architecture for FP that included a code snippet that the author wanted to decompose further. I don't know Haskell but I recognize enough to know that I've written many ...

Question 11

I've heard that Clojure macros are easier to write but not as reliable as Racket's hygienic macros. My question has 2 parts: How does gensym differ from hygienic macros? What do Racket macros provide ...

Question 12

Trying to learn Clojure and you can't help but be told continually how Clojure is all about immutable data. But you can easily redefine a variable by using def right? I get that Clojure developers ...

Question 13

I'm in the process of making a simple game using re-frame (and thus react and reagent), but I'm stuck at one point. In https://github.com/Day8/re-frame#control-via-fsm they claim Not every app ...

Question 14

I am making a neural network in Clojure that can take an array of integers,and return a data structure representing the layers of a neural network: so (make-layers [1 4 5]) would evaluate to: [[0] ...

Question 15

I am new to Clojure and trying to get a handle on organizing a project's namespaces. I am working on a solver for the knapsack problem. Currently, I have broken the modules into files, but everything ...
