[ANN] Liverpool Clojure talk on LiveStream: Deploying apps on OpenShift
I wouldn't normally announce this on the main list but it may be of interest to some since I haven't seen much about Clojure on OpenShift. We're having short talk from Steven Citron-Pousty (@TheSteve0https://twitter.com/TheSteve0), a Developer Advocate for RedHat about deploying Clojure apps on OpenShift ( https://openshift.redhat.com/app/) prior to the Clojure Dojo on 29th January at DoES Liverpool (http://doesliverpool.com/). Steve's talk will be on LiveStream.

Re: Who's using Clojure?
London Clojurians has a periodic update of who's using Clojure in production. The latest thread is here: https://groups.google.com/forum/?fromgroups#!topic/london-clojurians/ES8AuxXI0Nk There are a few here that haven't been mentioned elsewhere such as Likely.co, MastodonC, uSwitch, Trampoline, UBS, Deustche Bank. I think I covered them all :) Simon On Tuesday, 19 April 2011 15:38:14 UTC+1, Damien wrote: Hi Everyone, I'm on a mission: introducing Clojure in my company, which is a big consulting company like many others. I started talking about Clojure to my manager yesterday. I was prepared to talk about all the technical benefits and he was interested. I still have a long way to go but I think that was a good start. However I need to figure out how to answer to one of his questions: who is using Clojure? Obviously I know each of you is using Clojure, that makes almost 5,000 people. I know there is Relevance and Clojure/core. I read about BackType or FlightCaster using Clojure. But, let's face it, that doesn't give me a killer answer. What could help is a list of success stories, a bit like MongoDB published here: http://www.mongodb.org/display/DOCS/Production+Deployments Is there a place where I could find this kind of information for Clojure?

Re: A/B testing in Clojure?
I was thinking of something along the lines of django-lean ( https://bitbucket.org/akoha/django-lean/wiki/Home) - clean perhaps :) I haven't implemented any A/B testing yet so I just wanted to get a feel for what other people are doing. The silence seems to indicate that people aren't! Having seen recent discussions about Rails, I can see that that the framework approach is not popular in the community so a library seems to be the way to go. I'd definitely be interested in putting something together. Time is a bit tight over the next month but I can do some then things free up. Have you any experience in implementing A/B testing? I've been doing some reading and can pass on some pointers to resources if that would be helpful.

Jim, this is really great! I have joined the google group and I'm looking forward to the next meetup! Great! Welcome to the group! as the website suggests i will keep an eye on the time and place as it says it is not always fixed...too bad I missed the clojurescript talk :( Yep, the ClojureScript talk was a real classic :) Well, it was my first ClojureScript talk anyway... btw, have you talked about the reducers lib? It is the first thing on my list to explore as soon as I return back to Manchester... Nope, but we would all be very keen to hear a talk on reducers ;) In case you missed it, the next talk is on August 13th 2012 - An introduction to Applicative Functors in Haskell by Ian Murray.

Re: Clojurians in the midlands (UK)
Hi all, sorry I didn't spot your emails before but you may not be aware of the Manchester Lambda Lounge which is a functional programming group: http://www.lambdalounge.org.uk/ The group used to be a solely Clojure meetup but we were few so Rick Moynihan (who has been the driving force behind the group) suggested that we broaden ourselves. Meetings are generally monthly but we may have a break for August - we haven't set a date yet. We've covered ClojureScript, Haskell and Scheme in recent meetings.

Re: Accessing vals in clojure.lang.PersistentVector
I missed your reply, Raek. Sorry. Your solution is very helpful. Cheers, Simon From what I can tell, you want to list the values and extract the value associated with :time for a map. The problem is that res is not a map, but a vector of maps. If you want to do these operations on every map in the vector you can use the map function (map as in to map): (map vals res) (map :time res) In the last example I made use of the fact that keywords also work as functions. (:some-keyword some-map) is the same as (get some-map :some-keyword). To play in the repl with the first value in the vector in the repl you can extract it with nth or get: user (def res ...) #'res user (def first-res (nth res 0)) #'first-res user (vals first-res) ... user (get first-res :time) ... // raek -- You received this message because you are subscribed to the Google Groups Clojure group.

Accessing vals in clojure.lang.PersistentVector
Hi,
I've retrieved some data from my database which is returned as a
clojure.lang.PersistentVector:
org.psmsl.netcdf.core res
[{:name BREST, :time #Date 1807-01-01, :rlrdata 6882M} {:name
BREST, :time #Date 1807-02-01, :rlrdata 6908M} {:name
BREST, :time #Date 1807-03-01, :rlrdata 6873M}...{:name
BREST, :time #Date 2008-11-01, :rlrdata 7140M} {:name
BREST, :time #Date 2008-12-01, :rlrdata 7088M}]
org.psmsl.netcdf.core (class res)
clojure.lang.PersistentVector
I thought I should be able to do:
(vals res)
but I get
clojure.lang.PersistentArrayMap cannot be cast to java.util.Map$Entry
and
org.psmsl.netcdf.core (get res :time)
returns nil
What am I doing wrong?
Thanks,
Simon

Re: Alternative structures to arrays?
Thanks for the pointers. I have played with Incanter a little but the vector of vectors seems a good option. Cheers, Simon On 22 déc, 09:08, Brian Hurt bhur...@gmail.com wrote: If I wasn't using Incanter (see Alex Robbin's reply), I'd probably just use a vector of vectors. If your matricies 70% dense, it's generally not worth it to try and use some sort of sparse data structure- the extra overhead of the sparse data structure will be greater than the savings of not representing the unpopulated areas. Vectors are actually a great trade-off, giving you almost the same access and memory costs arrays do, but with all the advantages of being immutable (multi-threaded goodness).

Hi Finn, who is taking the Stanford ai-class with Peter Norvig and Sebastian Thrun? I'm taking it. Really enjoying it too. . I'm doing now the advanced track and it is a lot of fun although we have no programming assignments campus students have programming assignments like pacman and this has to be done in python. I originally thought that I'd be trying to implement things in Clojure. In hindsight, while it's been interesting to look at the programming assignments, I wouldn't have had time for something in that depth. Have you tried? Good luck with it!
