I wonder if there is mileage in saying at the top of the session: "If you are here for your first dojo and don't have a working Clojure development environment, then please join the "setup" group that will be mentored by [insert mentor volunteer here] so that those that have their environments already tuned can dive straight into the problem(s) that get voted up." Also, putting a few "howto" links for setting up Emacs + Cider, Cursive, Vi(m) for Clojure dev on the Meetup page(s) and encouraging people who are coming to a Dojo to be "ready to code" might be a good idea?

@maleghast all good suggestions....I'll post them in the London Clojurians organisers group

maleghast08:02:59

Morning 🙂 Cheers @agile_geek - When I am able to attend dojos again I will be happy to get people as up-and-running as I am with Emacs + Cider. I don't claim to be an expert, but I have a setup that allows me to be productive 😉

All help is welcome. TBH most people just starting either use LightTable NightCode or more often we do 4Clojure and just use the browser based REPL http://www.tryclj.com/

has anyone ever seen this problem when trying to start a clj uberjar Error: Invalid or corrupt jarfile ?

thomas08:02:36

I can start the same jar (same md5) with out any problems on my local machine. but I get the above error on the test box. :thinking_face:

tcoupland08:02:55

same jvm versions?

thomas09:02:38

no, the working one is java 8, the failing one is java 7. I think that is the problem here.

thomas09:02:04

unfortunately the sysadmin doesn't seem to be in today 😞

glenjamin09:02:57

@rickmoynihan the practical sessions at def_shef are some of the best attended and rated

rickmoynihan10:02:51

glenjamin: Cool. Keep meaning to pay them a visit at some point.

glenjamin10:02:13

I keep meaning to do the same for lambda lounge 🙂

rickmoynihan10:02:10

I hadn’t realised you were commutable to manchester

glenjamin09:02:19

we usually split into pairs or larger, everyone does the same problem in any functional language, and then compare notes at the end

agile_geek09:02:27

@thomas are you running the standalone version or the other one?

tcoupland09:02:41

@thomas that's it then. You can adjust the class version output from the 8 one down to 7, to get you going for today

tcoupland09:02:06

using --target on the javac cmd

thomas09:02:23

good idea @tcoupland I'll give that a try

thomas13:02:38

updated the java version to 1.8... and now it works again. thank you for your help ( @tcoupland and @agile_geek )

tcoupland14:02:10

hurray! 🙂

Rachel Westmacott15:02:32

that sounds like the right solution
