i'm working in app express , socket.io. when started develop in app there not many information cluster. i'm trying implement cluster have problems this. i think problems can resolve global object can access cluster. so, questions two: there way create global object access values cluster? there way modify values of global object , value in cluster? thank you! so there can 2 approaches external storage : in cluster mode multiple processes act clusters , not recommend sharing global object , managing sessions keep these objects in sync between processes. recommend using redis or similar database (recommend redis quick , suites use case) global objects : yes, can create/modify objects copy of object in each process , have keep objects in sync. can use process.send() process , worker.send() workers master process. option see using libraries same : memored npm module or strongloops strong store cluster i prefer keeping process independent , use com

in angular project each page has controller. include partial used on multiple pages. in each controller initialize values access them inside partial. $scope.checkeditems = []; the in partial bind data it. <input type="checkbox" checklist-model="$parent.$parent.$parent.$parent.$parent.checkeditems" checklist-value="item.id"> the partial nested have use $parent multiple times access parameter within controller's scope. ugly. also, partial included in different places on different pages, scope depth isn't consistent. therefore on pages need go 5 levels, 8 levels, 4 levels, etc. is there easier way access controller's scope? it'd great if following worked. <input type="checkbox" checklist-model="$controllerscope.checkeditems" checklist-value="item.id"> create 1 service data exchange between controllers nested tree option in service create object parent->child structure,

i have question following case. want track content platform using google tag manager. however, not every time platform online gtm send data our internal server. therefore our concern if data collected during offline period kept or if loose them. know if there period during data collected offline through google tag manager kept , once gets online sent google analytics? thank you, lukas no, not how google tag manager works. gtm web javascript injection engine. bundles configured tags,triggers , variables selector engine , injects page. there no serverside component stores data. i'm sure 1 come solution problem - e.g. store data localstorage in browser, poll server see if available, , when it's online send data queue time parameter google analytics. has nothing gtm. having said this, hard understand use case - if server offline, data come ?

i'm having trouble working as.date function in r. have vector of dates i'm reading in .csv file coming in factor of integers or character (depending on how read in file, doesn't seem have issue), formatted %m/%d/%y . i'm going through file row row, pulling out date field , trying convert use elsewhere using following code: tmpdtm<-as.date(as.character(tempdf$mydate), "%m/%d/%y") this seems give me want, example, if starting value of 12/30/2014, value "2014-12-30" returned. however, if examine value using typeof() , r tells me data type 'double'. additionally, if try bind other values , store in data frame using c() or cbind() , in data frame, winds being stored 16434, looks me sort of different internal storage value of date. i'm pretty sure that's because if try convert value again using as.date() , throws error asking origin. so, 2 questions: expected? if so, there more appropriate way convert date end date-t

my case class contains enum parameter follows: case class user(role: userrole.userrole, name: string) object userrole extends enumeration { type userrole = value val admin, user = value } how model case in example: https://github.com/thiagoandrade6/cassandra-phantom/blob/master/src/main/scala/com/cassandra/phantom/modeling/model/genericsongsmodel.scala ? any code samples provided helpful. you need use enumcolumn , created reason. if want use enum key, need create primitive using default helper methods. you can use both flavours of defining enum. object records extends enumeration { type records = value val typeone, typetwo, typethree = value } object namedrecords extends enumeration { type namedrecords = value val 1 = value("one") val 2 = value("two") } object enum extends enumcolumn[records.type](this, records) in case be: object role extends enumcolumn[userrole.type](this, userrole) to use index, need: implicit val

i've got bunch of data need serialized string stored in kvp. i've got tons of ints , bools , , floats . take each one, bitconverter byte[] buffer.blockcopying single large byte[] . i need save large array of bytes string in keyvaluepair<string, string> . tried using encoding.ascii.getstring() big byte[] created, , tried reload level string code achieved using encoding.ascii.getbytes() . m_levelcode = encoding.ascii.getstring( bytes ); the array of bytes has tons of 0's, i'm guessing that's why m_levelcode string empty string. is there better approach i'm trying do? have 650 bytes worth of integers , booleans , , floats . need them saved string. 1 step further, i'd comma separate 5 of these single kvp conserve on individual keys since every area has 5 levels. there many ways convert bytes string string base64 = convert.tobase64string(bytes); string hex = bitconverter.tostring(bytes); var jss = new javascriptserializer(); st

suppose building python package following folder tree: main |-- setup.py |-- the_package |--globar_vars.py |--the_main_script.py when user performs anyway install it, like: sudo python setup.py install python setup.py install --user python setup.py install --prefix=/usr/local or well, using pip: pip install 'someproject' i want folder package installed saved on global_vars.py , in variable, eg: globarl_vars.py #!/usr/bin/env python3 user_installed_pkg = '/some/path/where/the/package/was/installed' there someway it? in advance. assuming someproject package well-formed python package (which can done using setuptools ), user can derive location use pkg_resources module provided setuptools package information. example: >>> pkg_resources import working_set >>> pkg_resources import requirement >>> working_set.find(requirement.parse('requests')) requests 2.2.1 (/usr/lib/python3/dist-packages) >

i using dataset create horizontal in horizontal orientation. similar has been proposed solution in r: how can make barplot labels parallel (horizontal) bars . however, number of labels in y axis of horizontal barplot chart little many (due problem in hand) , hence, overlapping on each other. is there way preserve barplot bin size , show subset of y labels in horizontal orientation of barplot? thanks, rajat here's 1 way it, can use nice solution interleave names data blanks: generate data set.seed(123) df1 <- data.frame(x = replicate(50, paste(sample(letters, 2, replace = t), collapse = '')), y = sample(1:10, 50, replace = t), stringsasfactors = false) make barplot, using subset of names barplot(df1$y, names.arg = c(rbind(df1$x, rep('', 50)))[1:50], horiz = t, las = 1) the main trick names.arg = c(rbind(df1$x, rep('',50)))[1:50] line. interleaves blanks between names data. effectively, replacing half of name

i have following scenario: interface itemsrepository { observable<list<item>> getitems(); } class getitems { private scheduler ioscheduler; private scheduler mainscheduler; private itemsrepository itemsrepository; getitems(scheduler ioscheduler, scheduler mainscheduler, itemsrepository itemsrepository) { this.ioscheduler = ioscheduler; this.mainscheduler = mainscheduler; this.itemsrepository = itemsrepository; } observable execute(susbscriber subscriber) { return itemsrepository.getitems() .subscribeon(ioscheduler) .observeon(mainscheduler) .subscribe(subscriber); } } now want unit test subscribeon , observeon called using correct scheduler s. the way did writing 2 unit tests follows: @runwith(mockitojunitrunner.class) class getitemstest { private getitems getitems;
