for instance, when i'm trying understand how wordpress theme coded, spend hours trying figure out php file generating element (for instance, div or link). is there way of detecting php file? you can use debug_backtrace() or debug_print_backtrace() dig deep , find out kinds of information, such when , functions called , files loaded. this useful finding out how wordpress theme coded . tell pretty everything.

var results = new regexp('[\\?&]' + name + '=([^&#]*)').exec(window.location.href); could u please explain exactlly happening in above line of code. thanks in advance. you create variable name of results scoped execution context. you invoke regexp constructor thereby instantiating object , pass string used regex. have way because can't concatenate regex literals outside data. the regex says match of \ , ? or & followed name variable, , literal = , make capturing group of every character besides & or # , 0 or more times. you call exec() method on new regexp object, window.location.href (the current url) argument. the return of assigned results variable. the capturing group's contents (if successful) in results[1] . or you getting param name :)

to describe mean, give example here: function y = f(x,a) global y = f1(x); function y = f1(x) global y = x + a; here, want variable 'a' used global variable can called subfunction 'f1' compute $x+a$. (my purpose reduce transformation of parameters) but function not work, unless define new variable 'b' restore value of 'a'. the question is, how can make 'a' global variable directly, without defining new variable? i not recommend use global variables, since pass function f . the behavior want can obtained without global variables, using nested functions : function y = f(x,a) y = f1(x); function y = f1(x) y = x + a; end end

has tried codendi , redmine , retrospectiva , trac ? or able make comparison between four? whichone better related: performance easy use installation and others and better operating system implement each of application ? many :) i haven't tried coded or retrospectiva i've used both redmine , trac, , in opinion, redmine better because: easier installation multiple projects out of box support git , mercurial support remote repositories support ldap authentication built in web based administration many plugins available and better looking default theme if care that initially more familiar python ruby, tended towards trac first time. redmine more powerful, more features out of box, , greater community of plugins available.

i have fun , seemingly simple perl challenge stumping colleagues. care take crack? project move forward. iterate through each xmlfilexf in directoryd, , each one: in modifythisfilemtf, copy wordblockwb , paste after last wordblockwb. in modifythisfilemtf, replace replacemerm contents of current xmlfilexf. directoryd has xml files way, really, don't have discriminate on filetype. also, it's fine hardcode contents of wordblockwb if prefer. modifythisfilemtf.txt contents: myfunc { // begin wordblockwb prewords "msg"=replacemerm postwords // end wordblockwb return 0; } directoryd contents: xmlfilexf1.xml xmlfilexf2.xml ...6000 more xmlfilexf1.xml contents: <foo/> xmlfilexf2.xml contents: <bar/> desired output modifythisfilemtf.txt contents: myfunc { // begin wordblockwb prewords "msg"=<foo/> postwords // end wordblockwb // begin wordblockwb prewords "msg"=<bar/>

i've been searching answer problem—with no luck far. here's code: var onewwindow = window.open(slink,'_blank'); onewwindow.addeventlistener('load',function() { alert('page loaded'); }, false); when popup window/tab opens handler called, if browse inside popup window, handler never called. why? , there way make work? the base idea user opens popup window , starts browsing in popup, while code in parent window continues working , monitoring happening in popup. popup page page on same domain. after loading popup first time, attached onunload handler it, call handler in parent window , timer start. parent window's script work contents of popup. however, problem comes lag, if timer runs out , old page inside popup still there, incorrect data , whole script stops. unable attach onunload handler after that. the onload handler set window whole, not document within window, why isn't handler called? also, script run of greasemonkey. do

i have wcf function takes complex type input parameter. how create , pass complex type (object properties) through call? thanks there 2 ways accomplish task. can use asp.net scriptmanager , have create javascript proxy wcf service or can use jquery's ajax functionality too. i've included links both examples below. using jquery/ajax: http://www.west-wind.com/weblog/posts/2008/apr/21/jquery-ajax-calls-to-a-wcf-rest-service using scriptmanager js proxy: http://blogs.msdn.com/b/kaevans/archive/2007/09/04/using-wcf-json-linq-and-ajax-passing-complex-types-to-wcf-services-with-json-encoding.aspx

see definition of system.array class public abstract class array : ilist, ... theoretically, should able write bit , happy int[] list = new int[] {}; ilist ilist = (ilist)list; i should able call method ilist ilist.add(1); //exception here my question not why exception, rather why array implements ilist ? because array allows fast access index, , ilist / ilist<t> collection interfaces support this. perhaps real question "why there no interface constant collections indexers?" , have no answer. there no readonly interfaces collections either. , i'm missing more constant sized indexers interface. imo there should several more (generic) collection interfaces depending on features of collection. , names should have been different too, list indexer stupid imo. just enumeration ienumerable<t> readonly no indexer (.count, .contains,...) resizable no indexer, i.e. set (add, remove,...) current icollection<t> readonly indexer

what benefit of binary search tree on sorted array binary search? mathematical analysis not see difference, assume there must difference in low-level implementation overhead. analysis of average case run time shown below. sorted array binary search search: o(log(n)) insertion: o(log(n)) (we run binary search find insert element) deletion: o(log(n)) (we run binary search find element delete) binary search tree search: o(log(n)) insertion: o(log(n)) deletion: o(log(n)) binary search trees have worst case of o(n) operations listed above (if tree not balanced), seems worse sorted array binary search. also, not assuming have sort array beforehand (which cost o(nlog(n)), insert elements 1 one array, binary tree. benefit of bst can see supports other types of traversals inorder, preorder, postorder. your analysis wrong, both insertion , deletion o(n) sorted array, because have physically move data make space insertion or compress cover deleted item. oh , wor

we getting ready in few weeks deploy new product brand new webservers , doing deployment testing in advance. (smart move? :-)) anyway, have 2 web servers (web01 , web02) , load balancers. stateless sessions setup machine keys setup on both web servers web01 stateless server. both http , https load balancers set 'not sticky' , 'sticky' hitting url web, not internally we can actively see web server have session @ given second, changing between servers. (should be? or should session more ‘static’ longer periods of time?) the app silverlight app. user logs in on web02 (we have lables on page can see server hitting) enters data. saves. take web02 offline. can see user on web01 error "an asynccallback threw , exception". if click ok user can continue if nothing happened. data there etc. should turn on tracing diagnose? have other suggestions? running fiddler , seeing 503 , 504 errors on web service can't tell server coming from. t

when client invokes rest-ful service, needs know if response came 'from me' or rather diagnosis containing web server awful happened. one theory that, if code called, should return http ok(=200), , errors i've got return should represented in data return. after all, it's code gets response, not naked browser. somewhat self-evidently, if i'm using rest generate html read directly browser, absolutely must return error code if there's error. in case care about, it's javascript or java interpreting entrails of response. another possibility there family of http status codes return high confidence it/they never generated problem in surrounding container. case? i use following: get 200 ok 400 bad request (when input criteria not correct) post 202 accepted (returned authorization method) 401 unauthorized (also returned authorization) 201 created (when creating new resource; set location header) 400 bad request (when data creating n
