i trying loop around value got populated in registration class. have put breakpoint in getinstance() method in registration class. when cursor reaches below loop code. for (final registration.holderentry entry : registration.getinstance()) { // other things.. } i f5 on that. , gooes getinstance() method of registration class (below class). , when inspect on instance variable @ point, see values populated in listofbundles list good. but if keep on pressing f5 again, @ point comes iterator method in registration class , if inspect on listofbundles list , don't see values in list not able understand why happening this. no other code running might change value of listofbundles . public class registration implements iterable<registration.holderentry> { private list<string> listofbundles = new linkedlist<string>(); private final map<string, holderentry> bundlemapper = new hashmap<string, holderentry>(); private regist...

i planing write 1 customized http server in java. thought of using 1 listener port listen incoming calls. whenever incoming call come, accept , pass socket object in thread. thread responsible serving response. when response completed, closed. problem think if request comes @ time no more port available. thinking of having fixed number of serving port , reuse sending response back. can suggest how can in java? you don't want limit ports as want limit threads, that's why many servers use threadpool contains way less threads amount of available ports.

i have web page encoded in utf-8, need include subpage iframe encoded in gbk. so wonder how browsers(ie/chrome/ff) render characters of whole page ? browsers treat iframe page standalone page , use own encoding charset ? thanks ! in general, browser treat iframe page standalone page if being rendered in separate tab or window. there is, however, issue some versions of internet explorer content of iframe not set encoding through content-type, , picks parent window's encoding on initial load.

is there way select top layer element on hover? for example, let's have 2 divs. in first 1 top layer span.mytext1, if hover off span remain in div, div top layer hover over. similar example applies second div, except has more layers. i .addclass('outline ') top layer only. css .outline { outline: 5px solid #66ff66; } html <div class="divs"> <span class="mytext1">some text</span> </div> <div class="mydiv2"> <div style="width:300px"> <span class="mytext2">some text <button value="mybutton"></span> </div> </div> i think .hover() way go not sure how. $(mytoplayer).hover( function() { $(this).addclass('outline'); }, function () { $(this).removeclass('outline'); } ); update - misunderstood question; previous answer doing opposite o...

i needed find safe bool idiom solution. know drill, i'm using vs 2012, xcode, gcc, llvm, various platforms, support c++11 explicit conversion operator , don't. needed portable. i found several, devised seems simple have ask, missing here? background (brief): several examples 1 web provide either highly intrusive methods (essentially putting required inside given class), or generic approach using crtp, based on pointer member function (which of wildly unpredictable size , performance penalty). then read boost::spirit::classic safe bool, tried it, examined it, etc. liked spirit's implementation depended upon pointer member data rather pointer member function (with compiler workaround 'obscure' versions). so thought, doesn't matter type pointer member based upon, implementations working because, among other things, these pointers members of other objects we're use. so, tried kind of thing (and i'm wondering if i'm way off or ok this) ...

so seems safari (latest version) not following code involving background image: div.nav_element.pdf { background-image:url("/images/pdf_icon.png"); background-position: right 19px bottom 50%; background-repeat:no-repeat; } <div class="nav_element pdf"> <a class="nav_link" href="#">summary of product characteristics</a> </div> it tells me background-position property invalid via little yellow exclamation point box. has seen before? not relative sizing? because background-position property invalid. have 2 values, not 4. read this

i writing simple image viewer lets user flip through tens of thousands of images, 100 @ time. images files on disk. in order viewer function, must continuously preload images ahead of user's current 1 (or viewer unusably sluggish). the basic recipe i'm using display images in grid of tkinter labels, following (this has been tested , works): def load_image(fn): image = image.open(fn) print "before photoimage" img = imagetk.photoimage(image) print "after photoimage" label.config(image=load_image("some_image.png") i need imagetk.photoimage instance display image on label. have implemented 2 different approaches, each associated problem. first approach: launch separate thread pre-loads images: def load_ahead(): fn in images: cache[fn] = load_image() threading.thread(target=load_ahead).start() top.mainloop() this works quite on linux machine. however, on machine (which happens running windows, , compiled p...

i looking hpc networking library can more permanent standard java networking libraries. i have checked out netutils , rocksaw not sure whether maintained more. not community behind them. there many alternatives rather depends on requirements. i suggest kernel bypass adapters low latency, in cause current libraries supported, hardware (and drivers) changes, not library. if concerned throughput, system should able make full use of 1 gb line , can use 10 gb line tuning of software (again library won't help) what library lower level access, packet sniffing, sending/receiving packet types not supported. where libraries can handing large number of connections. plain io can handle on 1000 connections easily, , nio can handle on 10k connections if need 100k connection may struggle. if need 1+ million connections, need custom c library. @ point suggest having more machines can't 1 millionth of machine each user. in short, if want high performance, @ hardwar...
