good morning. when tring pre-compile (i dont know real name of this..) father c'tor this: point_3d(int _x, int _y, int _z) :point_2d(_x, _y, _z), z(_z+100){}; its working. when trieng this: point_3d(int _x, int _y, int _z) :point_2d(_x, _y, _z), _x(4), z(_z+100){}; it doesnt. (the '_x' parameter belongs father.) , little question: why cant pre-compile '=' , must use '()'? thanks! assuming _x(4) refers member of point_2d class, can initialized owning class, not derived classes. the initalizer list can contain base classes , members of current class, not members of base classes. but wouldn't point_3d(int _x, int _y, int _z) :point_2d(4, _y, _z), z(_z+100){}; ___________________________________________^ do want?

in web application,i have made pin popup supposed popup , disable rest of screen after timeout. when page refreshed(ctrl+r) or clicking on refresh button, pin popup appears, if link highlighted , enter key pressed, popup not come. how (click on link , press enter) different (ctrl+r) or clicking on refresh button? please in advance. generally: clicking on link (or tab , enter/space) starts new (get scratch (like open new browser , paste url in address)). while refresh/ctrl-r resends previous command - if post post. you can use ctrl-f5 new get. in addition: element on page (specifically link in case) may have event handler applied can stop default action. so, if yout link has event handler contains e.preventdefault(); or return false; (eg <a href='...' onclick='return false;'>link</a> ) appear nothing happening. pressing enter/space on focused link same clicking (runs .click() event handler).

i'm trying learn spring boot implementing simple rest api. my understanding if need transfer object on wire, object should implement serializable. in many examples on net though, including official ones, domain classes need transferred server client (or vice-versa) not implement serializable. for instance: https://spring.io/guides/gs/rest-service/ but in cases, do: for instance: https://github.com/szerhusenbc/jwt-spring-security-demo/blob/master/src/main/java/org/zerhusen/security/jwtauthenticationrequest.java is there general rule of thumb on when implement serializable? using java serialization api means need in java on other side of wire deserialize objects, have control code deserializes code serializes. this typically isn't relevant rest applications, consuming application response business of else's code, outside organization. when building rest application it's normal try avoid imposing limitations on consuming it, picking format more t

i'm processing couchdb view has on 10 million rows returned. there way iterate on rows "clean up" memory after i've processed row? for example, in django can use queryset.iterator() prevent queryset caching helps memory consumption. this i'm doing: couch = couchdb.server(url) couch.resource.credentials = (username, password) db = couch[database_name] result = db.view('xxx/xxx', none, stale='update_after', reduce='false') total = 0 row in result.rows: total += row['value'].num my actual code more complicated please don't suggest using reduce in couchdb.

i'm testing api service using oauth tokens. have divide load per api service, therefore seperated services in different thread groups (also make requests in parallel). since extracted oauth tokens (you need acces token make request api) local thread groups, used small beanshell script write tokens csv file. later on, these tokens used when doing api calls. the problem i'm facing 'csv dataset config' element pre-loaded in memory (correct me if wrong), , because tokens arent received yet @ point api calls failing regex eof. happens few times after request succeed. implemented once controller api requests implement thinktime, helps waiting users authenticated , receive tokens. question 1: how can read token values in realtime csv file each api call (using custom code/beanshell)? question 2: how can make beanshell script (see below) rewrite whole csv file each time oauth2 sequence run (now keeps on appending it..) ? situation: issue fixed using 2 sepe

i'll try , explain more example. have square , want able initialise variable dimensions such (width,length) = (int, int) or (double, int) or (double, double) etc.. i know if wanted square have integer sides declare int width , int height how declare can take many forms ? eg: header.h class square { public: // constructor : initialise dimensions square(); // set dimensions template< typename t1, typename t2> setdim(t1 x, t2 y); private: // right ???? template <typename t> t width; template <typename t> t height; }; moreover, if create square how initialise variables 0. e.g: src.cpp square::square() { // correct ??? width = 0; height = 0; } it doable, need 2 different types width , height, if understand question correctly (and note rectangle, not square, technically speaking). #include <iostr

in firebase quide read array: https://www.firebase.com/docs/web/guide/understanding-data.html#section-arrays-in-firebase especially : however, developers storing arrays in firebase database, when data read using val() or via rest api, if data looks array, firebase clients render array. in particular, if of keys integers, , more half of keys between 0 , maximum key in object have non-empty values, firebase clients render array. latter part important keep in mind. is there way force firebase use map , never convert data array? configuration? in example in firebase have got structure that: { "0": { "drivers" : { "12" : { "latitude" : 50.076574, "longitude" : 19.9209708, "timestamp" : 1456311442329 }, "13" : { "latitude" : 50.0166148, "longitude" : 20.9863258, "timestamp" : 1456395866163 } } } }, { "1" : {

i had question requires theoretical ideas/solutions rather exact execution plans. i`m trying design ms access form (i have experience access it's been while , not enough practice), can compare 2 tables (table 1 , table 2) , gather list of names against other. now know how , query results. problem arises when have multiple other tables want compare table 1 , of them have different columns. this ongoing testing process , new changes introduced monthly/annually, want automated form can use button (or less time consuming using queries everytime). primary key have been useful since don't exist, full names best option. another question related is, if excel tables stored in local server folders, there way retrieve files our database without manual imports? pass-through queries? i don't mean throw work @ other people because of laziness, want overview of approach can take. advice appreciated! thank you. i want automated form can use button... this mac
