we developing app. user can draw object on map , want save location , map extent drawn graphics on our server using serialize json representation of state. , when user come afterward clicking location item want re-render same state last graphics had drawn on using same serialize json object server. how achieve feature in arcgis javascript api. need write our own feature layer if yes how it? typically use feature service store , serve data (graphics). can define , publish feature service either using local arcgis server installation , or in cloud on arcgis online . once have feature service published, connect using arcgis api javascript (jsapi) featurelayer . see of editing samples idea of different ways can use featurelayer , other modules jsapi manage data in feature service. you can (optionally) create web map references feature layer defines other map properties initial extent, basemap, etc , have app load web map. as far persisting other parts of map state (ext...

i use sockets , lot of messages server. there handler every socket message , invoke $apply in every handler. better performance use $applyasync instead of $apply if there lot of messages , if so, why? frequent invoking of $apply makes app slow. unless you're receiving more 1 message every 4ms ( minimum resolution of settimeout in modern browsers ), it's unlikely you'll see performance improvement - in fact might find performance degrades touch additional timers added , fired. if receive many messages, may find helps since batch processing single digest cycle. without knowing socket it's hard make solid suggestion, aggregate data socket receiving , digest every n updates or throttle digests occur every 500ms or that?

in visual studio 2013 have created mvc project individual account (asp net identity 2.x). so @ url account/register (anonymous) user can sign up. now want admin user can create user (and in view there additional fields respect register view). what's best way accomplish this? use same route , view (account/register) show field in view according role of user? or create route/controller/view admin? i think best ways is: create admincontrooler in asp mvc or webapi (if any) , there write method user role admin. like: [authorize(roles = "admin")] public class admincontroller : apicontroller { [httppost] public void createuser(userviewmodel model) { ... logic } } this best practice because if need add few new methods user-admin only, add in controller

data = 110 columns( x1: x100) (numeric) i trying plot columns using following code, x2=melt(x1) ggplot(x2,aes(x = value)) + facet_wrap(~variable,scales = "free_x") + geom_histogram(aes=(density)) +title(sub = s, line = 5.5) s<-summary(x1) i'm want append summary data every column in plot analysis . there alternate this? thanks. to knowledge, cannot add subtitles subplots of facet_wrap. change title accomodate want though. here example min, max, mean , median : data = data.frame(x1=rnorm(100), x2=rnorm(100), x3=rnorm(100), x4=rnorm(100), x5=rnorm(100), x6=rnorm(100)) library(dplyr) library(tidyr) library(ggplot2) x <- data %>% gather(variable,value) %>% group_by(variable) %>% mutate(mean=mean(value), median=median(value), min=min(value), max=max(value), ...
