Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

• The link in the table of content jumps at the copy of the answer on this page.
• The link on the answer itself points back at the original post.

Sate of Clojure - 2022 - Free Text Answers

A vaguely curated rendering of the free text answer in the State of Clojure 2022 survey. Answers are ordered by length and their title contains the original timestamp and a summary sentence which I added to make it easier to find them later. The rest of the text is the original with some formatting fixes.

• What can we as a community do to increase Clojure adoption?
• Who do you appreciate in the Clojure community and why?
• Who do you appreciate frequencies

State of Clojure Survey 2018 - Open comment question

This is a selection of the most articulated critique found in the open comments section Q25 at the bottom of the survey. Recurring themes are:

1. Elitism, ivory tower, "not smart enough to get it" attitude of frequent speaker or early adopters.
2. Poor basic documentation, error messages, beginner friendly resources.
3. Fear of contribution (with reasons like a. community-built tools open to attack and replacement by core team b. hostile contribution environment c. closed development process)

• The community has to grow to create more opportunities. Many organizations don't want to even consider using it because they fear not being able to find Clojure developers. Unless you have a mentor or are extremely motivated, Clojure scares away most imperative developers. My suggestions is to team up with a university and get a Clojure course on Coursera or a similar platform. This is the only way I got in

; The following is an attempt to answer the question: how to use stateful transducers with fork-join r/fold and what you
; should expect. Feedback appreciated. Feel free to discuss on Clojurians slack @reborg.

; Stateful transducers (for example drop, partition-by, dedupe etc.) cannot be used in parallel with fold. 
; They produce inconsistent results, for example:

(require '[clojure.core.reducers :as r])

1/8/2019 11:30 AM Clojure was my language of choice for quite a long time, but all the recent developments in the community[1] and lack of clear publicly available vision of the language's future alienates me greatly and makes me feel as an unwanted member of the community. Because of this I'm not considering Clojure anymore for any new development and don't really want to help growing the community by releasing new libraries/supporting existing ones, mentoring new Clojure engineers, speaking at meetups, or just simply recommending Clojure to people I know :( [1] Drift to being dogmatic and hostlie to any alternative thoughts community (or better say cult?), which started long time ago, reached unbearable level last year and I'm not interested in participating in any community even resembling a totalitarian one, even if the language itself is perfect (which Clojure is not). Disclaimer: my feelings are obviously mine alone and I don't claim it's the universal truth and "Clojure is dead", it's just my perso
