Let's say I have a namespace that provides access to the database, say our table has these fields (as clojure specs) (s/def ::job-id nat-int?) ; 1 2 3 ... (s/def ::job-name string?) ; frobozz-executor (s/def ::job-status keyword?) ; :queued, :in-progress, :completed And that I have the logic

Suggestions for state modification improvements in this bit of code?

I'm still learning clojure and wrote this decidedly unfunctional bit of code as part of a common lisp style DESCRIBE function. I was wondering what experienced clojure-ers (what's the proper reference?) might suggest to make this function less ugly. I realize making a purely functional version

With all my attention on trying to learn things about clojure, I've either missed or forgotten how do to a simple thing. As I learn clojure I'm writing a few definitions that represent tools I like to use in development. What is the simplest way to have those tools present in arbitrary clojure

What's new and exciting w.r.t. Clojure use in data & analytics, and cloud apps that scale out?

Just looking for interesting tidbits on recent spearheads with, or wins for, Clojure in the cloud with the buzzwords du jour. Part of an interest to take the pulse of Clojure in the domains for which my employer presently uses other tools. I like Java just fine (for what it is), and I have a lo

I don't understand why these things aren't equal. user=> (= (list java.lang.String) (list (class "abc"))) true user=> (= '(java.lang.String) (list (class "abc"))) false user=> (type '(java.lang.String)) clojure.lang.PersistentList user=> (type (list java.lang.String)) clojure.lang.PersistentList

Re: abysmal multicore performance, especially on AMD processors

As a person who has recently been dabbling with clojure for evaluation purposes I wondered if anybody wanted to post some links about parallel clojure apps that have been clear and easy parallelism wins for the types of applications that clojure was designed for. (To contrast the lengthy discu
