I'm writing a blog post about Reader Conditionals, I'd be happy to have some feedback before I publish it if anyone's interested - https://gist.github.com/danielcompton/bd07ce46d14d5849be57

@danielcompton knee jerk splice top level into a do don't have two reader splices

@danielcompton: like your mention about top-level form gotcha

@arrdem: ha-ha, same reading timing

Other than that looks good!

@arrdem: that's a fair point, could look a little funky with the do, but I'll mention it.

Sure.

I got really confused on an older 1.7 release before they added the exception. Before that it would just silently fail. I was converting a ns to reader conditionals and wrapped the whole thing in a splice and it didn't work as expected

btw, people interested in cider might checkout the dedicated #C0617A8PQ channel

I’ll be keeping an eye on it from time time, so feel free to ask questions and discuss problems/suggestions about cider there

Hey! Just curious … is there something like a durable/persistent atom? I don’t need a full database, just an atom that is able to survive application restarts

API wise I guess it would be similar to the durable queue from Factual

meh I’ll just opt for Redis I guess … seems more pragmatic in this case I guess.

@joelkuiper: https://github.com/pesterhazy/perdure

@joelkuiper: uses git as storage backend

interesting approach

https://github.com/alandipert/enduro

maybe I do need a database, just haven’t realised it yet. But it’s on a single proces, on a single machine, multi-threaded though. It’s for maintaining a simple id -> meta-data map

@joelkuiper: just writing the contents of an atom to a file and read it back in also works of course

@borkdude: well yes, but then I need to watch the atom for changes and keep flushing out to disk each time something changes. I was hoping somebody already did that, since it can involve some peculiarities 😉

@martinklepsch: the file backed atom seems to be at least very similar to what I had in mind … I’ll play with it, thanks

@joelkuiper: very simple implementation w/ Nippy serialization https://bitbucket.org/ul/runes24/src/931419f4619ac7882b0c0970ebcac6cc9bddbc59/src/clj/runes24/edb.clj?at=default

should work multithreaded because of go-loop

@joelkuiper: it seems to do just that https://github.com/alandipert/enduro/blob/master/src/alandipert/enduro.clj#L60

yep I’ll try enduro! it would have been easy to write, surely, but not as easy as asking the power of the interweb 😉

@joelkuiper: very true. and you can swap it for postgres later

thanks everyone!

How do I make Quil on MacOS create Dock icons for my sketches? The following doesn't help:

;; In core.clj (before defsketch)
(System/setProperty "apple.awt.UIElement" "false")

;; In project.clj
  ... :jvm-opts ["-Dapple.awt.UIElement=false"]

The Quil FAQ shows it's something of a mystery... https://github.com/quil/quil/wiki/FAQ#i-cannot-see-sketch-on-os-x

hey friends, i was curious how you guys typically auto start clojure apps? i was considering using supervisord to manage the standalone jar and nginx as proxy in front of that clojure web app.

Wrote a blog about leiningen -> boot: http://blog.michielborkent.nl/blog/2015/06/06/from-leiningen-to-boot/

does this sound crazy? (if you have an opinion or advice could you atmention me) thanks!

@chadhs: I usually have something in /etc/init.d

@chadhs: We just use an upstart script. (And nginx as proxy too.) I'll look later at supervisord to see if it has advantages over upstart, thanks!

@chadhs: I use upstart and nginx as well. Works great.

Thanks all! Was considering supervisor to avoid writing different init scripts for Ubuntu and FreeBSD

But that may be bad reasoning

i use supervisord a lot and nginx, although for one of our high volume apis we use uwsgi with nginx to load the ring app

Honestly, only reason why I use upstart is because it’s what was there when I jumped from Heroku to DigitalOcean.

Meaning I never researched pros/cons/etc.

Cool thx :thumbsup:

@minimal: interesting on uwsgi

@chadhs: It’s really fast and has some interesting features http://uwsgi-docs.readthedocs.org/en/latest/Ring.html

@minimal: sweet thx for link

Hey all, I’m looking to totally gut and simplify my test suite for a web project I have… I have too many mocks, and the integration testing is brittle, because of occasional schema and/or API changes. Any suggestions on tools that might make this easier, or approaches to testing that are specific to Clojure?

Clojure related blog post on #9 at Hackernews

@borkdude: 👍!!

@jmckitrick jessica kerr / jessitron had a blog post on this topic recently

@jmckitrick http://blog.jessitron.com/2015/06/ultratestable-coding-style.html?m=1

@jmckitrick: write your app using https://github.com/stuartsierra/component, then only use components while testing

@jmckitrick: makes mocking unnecessary, because you can just replace the component

but I also strongly agree with separating logic from side-effects

@chadhs: there was a recent post on the Clojure mailing list about running Clojure programs with supervision
