i'm working kue workers set , have discovered strange. if create queue using default kue redis connection works perfectly: var kue = require('kue') , redis = require('redis'); var q = kue.createqueue(); q.process('cypher', function(job, done){}); the worker starts perfectly. however, if try override default redis connection 1 of own error: connection in subscriber mode, subscriber commands may used when execution hits q.process function below: var kue = require('kue') , redis = require('redis'); var redisclient = redis.createclient(); var q = kue.createqueue({ redis: { createclientfactory: function(){ return redisclient; } } }); q.process('cypher', function(job, done){}); it doesn't seem sense. thought maybe committing classic async error, following same error. any insights? redisclient.on('connect', function () { console.log('gotten here!!

i make == generic function. when run: setgeneric("==") , definition not appear change: > `==` function (e1, e2) .primitive("==") > setgeneric("==") [1] "==" > `==` function (e1, e2) .primitive("==") and when call setgeneric("`==`") , following error: > setgeneric("`==`") error in setgeneric("`==`") : must supply function skeleton ‘`==`’, explicitly or via existing function i can define == function with: `==` <- function(x,y) 42; and can use setgeneric on it. i'd have put body of original == there, seems clunky. so there way make == generic in s4? thanks mrflick's response: it turns out == generic (implement in c). don't need call setgeneric . rather, can use setmethod . setmethod("==", c(e1="class1",e2="class2"), funciton(e1,e2) { .... })

this question has answer here: setup/teardown (@before/@after) why need them in junit? 6 answers being new junit have done far setting dependencies (i.e. creating objects) within test methods itself. questions: eclipse mocks unused variables, though. setup , teardown for? is practice create objects within setup , null them out via teardown ? what other use cases methods above? what purpose of working pre-suite setup , teardown . can give example when comes in handy? cheers, andrew being new junit have done far setting dependencies (i.e. creating objects) within test methods itself. if initialized , cleaned correctly there nothing wrong approach. have way, if different tests need different dependencies. eclipse mocks unused variables, though. setup , teardown for? unused variables have nothing setup , teardown methods. should eit

i have app using nsfilewrapper create backup of user's data. backup file contains text , media files (compression not relevant here). these backup files quite large, on 200 mb in size. when call nsfilewrapper -writetourl... appears load entire contents memory part of writing process. on older devices, causes app terminated system due memory constraints. is there simple way avoid having nsfilewrapper load memory? i've read through every nsfilewrapper question on here find. suggestions on how tackle this? here current file structure of backup file: backupcontents.backupxyz user.txt - folder1 - audio files asdf.caf asdf2.caf - folder2 - audio files asdf3.caf again, please don't tell me compress audio files. band-aid flawed design. it seems move/copy of files directory using nsfilemanager , make directory package. should go down path? when nsfilewrapper tree gets written out disk, attempt perform hard-link of or
