so have 2 sites, 1 @ somethin.site.com, , routed somethin.site.com/prefix/ i'd move /prefix/ bundle somethinelse.site.com, i've changed route set bit: my_bundle: resource: "@mybundle/resources/config/routing.yml" host: %host% requirements: _scheme: https the problem when go either url, somethin.site.com, or somethinelse.site.com, receive main site bundle, has prefix of '/'. there i'm missing? edit : interestingly, moving host , main_host params under requirements got sort of work. problem going wrong subdomain. if switch names or requirements, both subdomains route same bundle again. possibly due having multiple subdomains, ie (staging.sub1.site.com , staging.sub1.site.com)? pastebin of routing.yml in routing first match wins. main bundle may imported before specific bundle. either move my_bundle import first or set host: %main_host% other imports.

i need use c++ code in android app, i'm doing using ndk/jni. have able use java objects in c++. (note: not using c++ methods in java.) my problem ide. have c++ code in folder called 'jni' in android project. have installed cdt in eclipse. helloworld c++ project works fine confirming cdt set fine. what not know how run c++ code? thanks in advance! you going need native method in class signature such as native void processdata(byte[] data); then in jni code need c function correct name extern "c" jniexport void jnicall java_your_package_and_class_processdata(jnienv* env, jobject clazz, jobject data); the javah tool can right names match java class. in native code , have reference class instance , byte array. can access data in byte array using jni methods provided through jnienv instance. android jni tips page has on this, should read rest of page if new jni. i have assumed modifying data in byte array if need return in new byte array...

i'm huge noob. finished java textbook , i'm making game learning experiment. i'm stumped... here' problem: i have 6 objects created person class. each object has boolean variable, automatically set false. i can select each person object combo-box , display information them, can display information use link object combo box (as in: person1.name allows me display name variable on combobox, , allows me display name elsewhere). i want able change other instance variables within each object. know how make method change each object, i'd have make 6 methods, 1 refers each specific object. i want change boolean instance variable object user selects combobox. thought array of objects, i've been failing set array. array right way go? or there way? assuming jcombobox contains reference person object, should provide suitable getters , setters allow access value contain within object. for example... public class person { private string...

when developing python package, it's convenient use -m option run modules inside package scripts quick testing. example, somepackage module somemodule.py inside it, invoking python -m somepackage.somemodule from directory somepackage resides run somemodule.py though submodule __main__ . using calling syntax important if package using explicit relative imports described here . similarly, convenient use -m option debug script, in python -m pdb somescript.py is there way both @ same time? is, can call module though script , simultaneously launch debugger? realize can go code , insert import pdb; pdb.set_trace() want break, i'm trying avoid that. after experimenting quite time, turns out approach works: python -c "import runpy; import pdb; pdb.runcall(runpy.run_module, 'somepackage.somemodule', run_name='__main__')" for reason, use of pdb.runcall on pdb.run important.

when c-h f or c-h v , tells me in file symbol defined or autoloaded from. how can find same information programmatically? some digging reveals (find-lisp-object-file-name object type) should trick. example: (find-lisp-object-file-name 'goto-line 'function) ;; => "/usr/local/cellar/emacs/24.3/share/emacs/24.3/lisp/simple.el" edit: how discovered information: first did c-h k c-h f figure out c-h f bound to. result describe-function , let's c-h f describe-function see source that. noticed interactive wrapper around describe-function-1 , jumped source that. there's lot of stuff in there, pertinent line is: (file-name (find-lisp-object-file-name function def)) revealing find-lisp-object-file-name function used work internally.

i have directory of xml files. each file has own unique identifier. each file contains 1 or more references other files (in separate directory), have unique ids. for example, have file named example01.xml : <file> <fileid>xyz123</fileid> <filecontents>blah blah blah</filecontents> <relatedfiles> <otherfile href='http://sub.domain.abc.edu/directory/index.php?p=collections/pageview&amp;id=123‌​4'> <title>some resource</title> </otherfile> <otherfile href='http://sub.domain.abc.edu/directory/index.php?p=collections/pageview&amp;id=4321'> <title>some other resource</title> </otherfile> </relatedfiles> </file> if file has multiple relatedfiles/otherfile elements, need create copy of file each @href , rename it, concatinating value of unique id in @href value of fileid . so, example, need c...

for example: function person() { //person properties this.name = "my name"; } person.prototype = { //person methods sayhello: function() { console.log("hello, person."); } saygoodbye: function() { console.log("goodbye"); } } function student() { //student specific properties this.studentid = 0; } student.prototype = { //i need student inherit person //i.e. equivalent of //student.prototype = new person(); //student.prototype.constructor = person; //student specific methods //override sayhello sayhello: function() { console.log("hello, student."); } } i know can achieve using: function student() { this.studentid = 0; } student.prototype = new person(); student.prototype.constructor = person; student.prototype.sayhello = function () { console.log("hello, student."); } but i'd continue use style first example , have cla...
