i have messaging application working not designed in elegant way (please, see image). manager fan of spring integration, suggests me change application according spring integration pattern (version 3). sending use ledgermessage serialized spring simplemessageconverter , sent in client spring amqp template. as 1 can see in diagram sending ledgermessage originated in several places, , content of message different. once message received sender have several options process message based on value of long orderid. choosing processing method based on ordereid not elegant way, because if orderid positive used further processing. in case of errors use log4j log error. theoretically can send email informing error. also, can send email informing end of batch operations taking long time. so, suggestion, graphical presentation appreciated.

i have slide out menu in app, , let know, i'm new ios/swift, if don't explain well, or use correct terms, that's why. i use swrevealviewcontroller library sliding out menu. the code use view controllers is self.view.addgesturerecognizer(self.revealviewcontroller().pangesturerecognizer()) the issue is, when app first opens, shows navigation item's title , on viewcontroller1(default view), when using slide out menu go viewcontroller2 or 3, , going viewcontroller1, whole navigation bar/item disappears. i tried use nav_item.title = "whatever" within viewdidload(), doesn't work, far when switch first view. funny thing is, if programmatically change title doing that, changes when first loads when change view2 , change view1, disappears. here few images of mean, if didn't explain enough, because said i'm still new. development of app coming along pretty because i'm going off android version i've had done while. here when first

i had function in r ( onestep below) took argument vector v , returned new vector v output function of input vector. iterated function niter times , kept output vectors of each iteration (which not same length , can end having length 0) in function iterate follows (minimal example) : onestep = function (v) c(v,2*v) iterate = function (v, niter) sapply(1:niter, function (iter) {v <<- onestep(v) return(v) } ) example : v=c(1,2,3) iterate(v,3) [[1]] [1] 1 2 3 2 4 6 [[2]] [1] 1 2 3 2 4 6 2 4 6 4 8 12 [[3]] [1] 1 2 3 2 4 6 2 4 6 4 8 12 2 4 6 4 8 12 4 8 12 8 16 24 i wondering compact , idiomatic way such recursive function returns intermediate results in julia? thoughts? (apologies if trivial new julia) not sure on compact , idiomatic front, how i'd it onestep(v) = [v 2*v] function iterate(v, niter) results = array(array, niter) results[1] = oneste
