ngroute - How to detect change in only query string parameters with AngularJS Route? -

i wanted work query string parameters along usual route parameters in angularjs application , have been following solution in post: how pass querystring in angular routes? the solution seems work: change route first $location.path , apply query string parameters $location.search . however, came across scenario route not need change query parameters need to. for example: moving from '/books/programming?id=123' to '/books/mathematics?id=234' works fine. however, moving from 'books/programming?id=123' to 'books/programming?id=124' not work. it seems angularjs notified changes on regular route parameters , not changes in query string parameters if query string thing changes in url, application not respond navigation. as verified angularjs 1.6.5, , according plunkr @jb-nizet, problem not occur anymore. question still remains missed earlier did not work. marking resolved not occur anymore.

i using code load/show/write images (opencv_python-3.3.0-cp36-cp36m-win32): import cv2 img0 = cv2.imread('original.jpg',1) img1=img0 in range(img0.shape[0]): j in range(img0.shape[1]): img1[i,j]=[0,0,255] cv2.imshow('original',img0) cv2.waitkey(0) cv2.destroyallwindows() note line 7 supposed show original image img0, shows modified image img1 instead (i.e. red rectangle). line 3 supposed create temporary copy of img0, not modify img0. wrong here? when using assignment operator (=) between mat variables, not copying data sharing reference. hence change in 1 getting reflected in another. please checkout : http://docs.opencv.org/2.4/modules/core/doc/basic_structures.html#mat-operator you need use clone() or copyto() achieve want. check them out here : http://docs.opencv.org/2.4/modules/core/doc/basic_structures.html#mat-clone

r - Transform function to a character string without losing comments -

i want transform functions character strings. can't directly transform class function class character, i'm using function list character logic. however, list removes comments functions. example: foo <- function() { 1 + 1 } # can't use as.character(foo), thus: as.character(list(foo)) "function () \n{\n 1 + 1\n}" however, if function contains comment gets removed bar <- function() { # sum 1 + 1 } as.character(list(bar)) "function () \n{\n 1 + 1\n}" question: why list removes comments functions , how save them? or better way transform functions character strings? edit: suggestion mrflick use capture.output works interactive r session. however, if use code.r : bar <- function() { # sum 1 + 1 } # collectmetadata() print(paste0(capture.output(print(bar)), collapse="\n")) and try run rscript code.r output still: "function () \n{\n 1 + 1\n}" i have no idea, wh

amazon web services - Elastic Beanstalk UDP support -

asking here due seemingly lack of documentation (perhaps intentional). i'm trying develop elastic beanstalk application includes multi-container configuration consisting partly of running container requires udp support -- statsd. understand elastic load balancer does not support udp packets. on other hand, ecs does support udp protocol. and elastic beanstalks multi-container configuration makes use of ecs docker image. i know can't send udp packets through configured elastic load balancer. if connect route 53 url beanstalk application, traffic go through elastic load balancer? when i'm looking is, route 53 url filters tcp traffic elastic load balancer, , udp traffic directly ec2 cluster. note this page lacking udp containers (elastic beanstalk) -- whereas this page includes mention of udp (ecs) , both referencing same type of portmappings list of objects.

ios - Variables in header file, memory management -

in ios, if put const variables in header file use them in different source files including header file, what's lifecycle of these variables? when these variables allocated/released? these variables stored? you asked: what's lifecycle of these variables? the lifecycle of globals life of app. when these variables allocated/released? they're not released until app terminated. where these variables stored? if you're talking primitive data types or string literals, they're stored in dedicated __data segment, not in heap, not in stack. you should not put implementation of const globals in header. put them in .m file. put external references them in .h file. so, example, put following in .m file: nsstring * const knotificationname = @"com.domain.app.notification"; and then, in .h file, put: extern nsstring * const knotificationname; that way, implement once, files import header have visibility it.

this question has answer here: how distinct values array of objects in javascript? 23 answers from following object items = [{ title = 'title 1', category = 'foo' }, { title = 'title 5', category = 'bar' }, { title = 'title n', category = 'bar' }, ] which i receive dynamically @ runtime can have length where each category field can have 1 of items.length values i want set of different values field category . in example above, result of get_all_possible_categories(items) would be ['foo','bar']. how can implement get_all_possible_categories(items) ? just map values array, using set unique values items = [{ title : 'title 1', category : 'foo' }, { title : 'title 5', category : 'bar

c++ - if constexpr instead of tag dispatch -

i want use if constexpr instead of tag dispatching, not sure how use it. example code below. template<typename t> struct mytag { static const int supported = 0; }; template<> struct mytag<std::uint64_t> { static const int supported = 1; }; template<> struct mytag<std::uint32_t> { static const int supported = 1; }; class mytest { public: template<typename t> void do_something(t value) { // instead of doing bool supported = mytag<t>::supported; // want if constexpr (t == std::uint64_t) supported = true; } }; one way define constexpr predicate checks type of argument, constexpr switch on result of predicate. i think way nice because separates functional logic precondition logic. #include <iostream> #include <cstddef> #include <type_traits> class mytest { public: template<typename t> void do_something(t value) { // define our pr
