this question has answer here: firebase analytics custom events params 6 answers i have started using firebase app's analytics , i'm having issues trying view custom parameters associated events. the problem when creating audience, can see events cannot drill down parameters (no parameters shown associated events) as example, i'd register event "add retail favourite" , pass, parameter, id of retail. final goal assess how many users had added retail favourite list. for ios i'm using piece of code: [firanalytics logeventwithname:@"add_retail_to_favorite" parameters:@{@"id_retail":idretail}]; and android: bundle bundle = new bundle(); bundle.putstring(firebaseanalytics.param.item_id, string.valueof(mid)); mfirebaseanalytics.logevent("pv_detail", bundle); am doing wrong? thanks support curre

is possible make php code on webpage send out code visitor run? like: <?php batch("echo text"); ?> then open cmd window says text. if not work in php work in launge? php runs on server , has no magical control on happens on else's computer. once page has loaded send requester's browser. from there have access local storage/cookies/etc., browser provides you. if browser give website access cmd, mean website read pretty on anyone's computer, or harm in many other ways. can imagine not secure. the way can execute batch commands on someone's computer if or program have access computer. in other words, user must download batch/.exe file , run manually.

i've xml file need delete elements depending on attribute value. unconditional deletion works fine won't: nodelist nodes = doc.getelementsbytagname("host"); element d; ( int = 0; < nodes.getlength(); i++ ) { string state = nodes.item(i).getchildnodes().item(0).getattributes().item(0).gettextcontent(); if("down".equals(state)){ d= (element) nodes.item(0); d.getparentnode().removechild(d); system.out.println(state); } } there couple of problems code. first line string state = nodes.item(i).getchildnodes().item(0).getattributes().item(0).gettextcontent(); which assumes 1) there no text nodes between child elements, , 2) attribute looked first attribute in list. makes code brittle , subject failure if format of input document change. the second problem while iterating on node list, of members of list removed parent. behavior of list

how select specific number of columns table in hive. example, if have table 50 columns, how can select first 25 columns ? there easy way rather hard coading column names. i guess you're asking using order in defined columns in create table statement. no, that's not possible in hive moment. you trick adding new column column_number , use in where statements, in case think twice of trade off between spending more time typing queries , messing whole table design adding unnecessary columns. apart fact if need change table schema in future (for instance, adding new column), adapting previous code different column numbers painful.

i have class representing parameter. parameter can number, array, enum or bitfield - param type. behavior different between these types, subclasses of parambase class. parameter can stored in ram or static (i.e. hardcoded in way, saved in file). void read() implemented in parambase , uses template method pattern implement reading param type, works ram storage. if parameter static read() must completely different (i.e. read file). a straightforward solution can further subclassing paramarraystatic , paramnumberstatic , etc. (it 8 subclasses). difference between paramarray , paramarraystatic in read() method, straightforward solution lead code duplication. also can add if( m_storage==static ) read() method , modify behavior, code smell(afik). class parambase { public: virtual paramtype_t type() = 0; paramstorage_t storage(); virtual somedefaultimplementedmethod() { //default implementation } voi

i have code this: a = [sparse(round(rand(4,4)))]; b = [sparse(round(rand(1,4)))]; c = [bsxfun(@minus,a(1,:),b); bsxfun(@minus,a(2,:),b); bsxfun(@minus,a(3,:),b); bsxfun(@minus,a(4,:),b);] is possible somehow define c way large amount rows (so cannot physically print command way) without loop (because loop take excessively long time)? one options: if prefer keep sparse matrix: c = - repmat(b,size(a,1),1); %but slower bsxfun version.

my intention here specify date in order. start d, followed d1, d2, d3, , end d". have initialised 'd = request.begin' first element while 'd"' last element in ordering. in following codes, define 'd1 = d.next', 'd2 = d1.next', and, 'd3 = d2.next'. in addition, invoked util ordering in library; 'open util/ordering [date] dateorder'. however, no instance found when executing codes. please let me know what's problem codes? open util/ordering [date] dateorder abstract sig resource {} 1 sig tour extends resource {date : 1 date, destination : tour_destination} 1 sig tour_destination {} pred holiday [disjoint d,d1,d2,d3,d": date , r:request, t:tour] { r.begin = d , r.end = d" t.date = d or t.date = d1 or t.date = d2 or t.date = d3 or t.date = d" d != d"} sig date{} pred init [d:date]{d= request.begin} fact traces { init [first] let d" = l

question how user.identity.getuserid() finds current user's id? does find user id cookies, or query database? or other methods? problem for reason, user.identity.getuserid() returns null when add valid bearer token http request header , send request controller's endpoint: // mvc controller action method [authorize] public httpresponsemessage(userinfoviewmodel model) { // request passes authorization filter since valid oauth token // attached request header. string userid = user.identity.getuserid(); // however, userid null! // other stuff... } when user logged app, server, using asp.net identity, validates user using db , creates valid token returns ui. token valid expiration , has inside information needed authenticate , authorize user, including user's id. next calls client side server side must done using token in http request header, server not call db again, because asp.net identity knows how decrypt token , informati

with excel 2010, trying sum individual cells rather range in row using sumif function. example: formula = sumif(c2,"<>",(k2+n2+q2+t2)) not work. must range , not individual cells? without seeing data you're working bit difficult answer question. sumif requires single cell reference or range of cells. can try breaking formula down multiple sumif formulas: =sum(sumif(c2,"<>",k2),sumif(c2,"<>",n2),sumif(c2,"<>",q2),sumif(c2,"<>",t2))

so have php controller sends cookie in queue, , need cookie next time when refresh page (and call controller). when controller called, checks if cookie exists in request, if not, sets in queue expiration time 15 minutes. but when controller called again, nothing got in request. i've looked in dev-tools->network->cookies , haven't found cookie neither in request nor in response section. @ same time, getqueuedqookies() shows cookie has been added queue. code looks follows: $cookie = $this->request->cookie('id'); if($cookie=='id') { die('id detected.'); } else { $this->cookiejar->queue('id', 'id', 15); } then other actions taken, , controller returns string in end. what doing wrong , how can problem solved? highly appreciate possible help! update change test function name , cookiejar auto injected. public function test(cookiejar $cookiejar, request $request){ $cookie= $request->cook

we have multi-tenant angular js single page application. routing application uses customer identifier part of url - #/home/<key> or #/search/<key>/<search term> instance. in theory first page served of type. each page calls api using customer key , other values picked url data page. far good. we have parameters - logo, copyright statement, default language (for internationalization) - can loaded using separate api call uses customer key. these parameters need available strings in partials, drive internationalization , perhaps in controllers. the question call api these parameters , how set them / make them available rest of app. have looked @ bunch of questions in general area can't find concrete suggestion. should use config in app.js? call script index.html? appreciate people's advice. the right place make api call after authentication various customer specific configuration data customer settings logo, language , put them in session st

i doing paging using limit , offset: test.query(function(q){ q.where('testname', 'like', '%test%') .orwhere('testno', '1234') .limit(limit) .offset(offset); }) .fetchall() how can total count without limit? you need use model.count think following should work var q = test .where('testname', 'like', '%test%') .orwhere('testno', '1234'); q.limit(limit) .offset(offset) .then(function(results){ q.count('id').then(...) })
