i using sails.js in node app. sails of course globally available default. however, want services , models non-global peace of mind. set default booleans in globals.js false , trying access specific services per sails.js documentation (sails.services.*) should work since sails still global, keeps throwing reference error. ideas why is? have experience mucking around global.js in sails , can confirm of documentation of sails.js innacurate? starting lean towards conclusion. note: using sails.js version 11 if accesss service trough sails.services.xxx make sure letters lower case, example if have myservice.js @ services folder, can call myservice or sails.service.myservice .

in java project have server class(using serversocket) , client class(using socket). in addition implemented servlet application running on tomacat 8 servlet acts input source(in other words client). i'd send data filled servlet web page server socket. got data web form using request.getparametermap() command i use json in order wrap data before sending between client , server. i'd same servlet cant find right way that. thanks! as have client class need use effectively. make client code generic simple interface can called anywhere. servlets java classes, can call other class additional work. in case, can use data received in servlet , pass on client send server. make sure client code should not block servlet long decrease responsiveness. if can client logic in separate thread servlet can respond quickly.

in r, noticed odd behavior regarding eval.parent , environment searches when evaluating variable names. following example: > f = function() {i = 1; g()} > g = function() {eval.parent(substitute(i))} > f() [1] 1 this works expected. expression i evaluated in environment called g , body of f , , 1 result. however, if define i in body of g well, value used instead despite expression being evaluated in parent frame. > g = function() {i = 2; eval.parent(substitute(i))} > f() [1] 2 why result 2 in case? definition of i = 2 should ignored eval.parent because expression evaluated in parent frame. having examined environments more closely, call eval eval.parent passed environment corresponding frame of f checked sys.frames .

well not sure if questions asked before have no idea how search it. not entity framework specified question gonna give example using it. so in ef need use .include("related object") include related data. want write method takes list of strings , returns entity or entity list related objects. in example public list<entity> getall(list<string> includes>) { list<entity> entites = context.entites; foreach(string s in includes) { entites.include(s); } return entites; } obviously above example won't work since called out entites when declared list. think demonstrates point. declare local variable dbquery<entity> , reassign result of include call , call tolist on after loop: public list<entity> getall(list<string> includes>) { dbquery<entity> entites = context.entites; foreach(string s in includes) { entities = entites.include(s); } retu...

i'm unable load packages parallel processes in foreach %dopar% loop. i create 4 sock clusters using foreach , dosnow packages, try run trivial parallel process. works %dopar% without using packages, loading arbitrary package throws error. sample code below, followed session info showing packages in use. i have used type of code before without issues. recent network changes @ company meant had change settings (default library path, etc), may related change. not sure start in troubleshooting issue - appreciated! #load foreach , dosnow packages, setup 4 clusters# > require(foreach) > require(dosnow) > registerdosnow(makecluster(4, type = "sock")) > getdoparworkers() [1] 4 > getdoparname() [1] "dosnow" # %dopar% loop without loading packages -- works ok # > foreach(i=1:2) %dopar% { i+1 } [[1]] [1] 2 [[2]] [1] 3 # %dopar% loop loading package -- not work # > foreach(i=1:2,.packages="forecast") %dopar% { ...

i working hadoop map-reduce. have process data .xml file, parse , store output database. while working on when need pass xml mapper, found xmlinputformat.class not provided hadoop default , have use mahout's xmlinputformat it. i wonder when xml being use vastly, why hadoop haven't provided xmlinputformat rather explicitly creating custom xmlinputformat bye extending textinputformat it? well though xml vastly used, providing framework special features towards technology, might not idea. may endorsement. @ high level, mapreduce designed accept different formats. infact these days json being used vastly due size features compared xml. had similar issue. but user decide input of map reduce , can use, different parsers(jackson or gson json , jaxb xml) if in single line or above using recordreader implementation

i want use ggvis data exploration (because familiar ggplot2), , of great help, due many groups in data sets, able select , unselect groups make different specific (data) comparisons. set.seed(10) dat <- data.frame(x=c(1:3,1:3),y=rnorm(6),groups=factor(rep(1:2,each=3))) library(ggvis) dat %>% ggvis(~x, ~y) %>% layer_points(fill=~groups) # know example not work - possible somehow? dat %>% ggvis(~x, ~y) %>% layer_points(fill=input_checkbox(~groups)) what want @ end, graphic can select subset of groups using radio buttons (for example). there way that? thank you! from documentation limitations currently, interactive inputs can used in 2 places: as arguments transforms: layer_smooths(span = input_slider(0, 1)) as properties: props(size = input_slider(10, 1000)) this means interactive inputs can modify data, not underlying plot specification . in other words, with basic interactivity there’s no way add or remove layers , ...
