when using infinite loop trydequeue queue, uses cpu. is possible make operation execute user interface notification, when queue not empty? , run event or function? i reached conclusion in implementation uses zeromq library, in thread responsible publishing, infinite loop can not avoided. using (var context = new context(1)){ using (socket client = context.socket(sockettype.pub)){ while (!stopallthread){ sqlqueue.trydequeue(out message); if (message != null){ ... } } } it's not clear api or technology use, guess there should blocking alternative, such var message = sqlqueue.dequeue(); in general case block thread until message read queue. shall not consume cpu when there nothing read. if use zeromq (from comment) there blocking call on server ( taken here ) // zmq context, server socket using (zmqcontext context = zmqcontext.create()) using (zmqsocket server = context.createsocket(sockettype.rep)) { server.bind("t...

i using .cacheondisc() method storing images in cache memory (default method-unlimited extrenal storage).should enable cacheinmemory app?what r effects if dont use cacheinmemory option? a memory cache caches images in memory (ram), i.e. not have load , decode image internal storage because rather slow. should imo use memory cache. the effect of not using memory cache can - depending on implementation - scrolling through lists of images either stuttering or slower necessary. disk (e.g. sd card) cache makes sense if images downloaded internets , don't want re-download them each time app starts again. local storage faster internets still slower memory.

for example: app.scss @import url('orange.css'); @import 'navel.scss'; orange.css .orange { color: orange; } navel.scss .navel { @extend .orange; } in sass if add @import "test.css"; or @import url("test.css"); it compiled pure css @import directive. because file .css extension sass preprocessor things pure css , code inside not involved in sass language operations. in example, if try extend .orange get: the selector ".orange" not found. shortly: extending possible if use sass files.

i saw code today in fb profile, , not able understand , how working:- (*(void(*)()) shellcode)() can please explain me, above code mean ? full code snippet below :- #include <stdio.h> #include <string.h> char *shellcode = "\x31\xc0\x50\x68\x2f\x2f\x73\x68\x68\x2f\x62\x69" "\x6e\x89\xe3\x50\x53\x89\xe1\xb0\x0b\xcd\x80"; int main(void) { fprintf(stdout,"length: %d\n",strlen(shellcode)); (*(void(*)()) shellcode)(); return 0; } it cast function pointer (with no returned result , no arguments). prefer using typedef define signature of such functions: typedef void plainsig_t(void); then code (*(plainsig_t*)shellcode) (); for function pointers, don't need dereference them, shorter code: ((plainsig_t*) shellcode) (); which calls function machine code located inside shellcode memory zone. btw, not strictly portable c. in principle, there no guarantee can cast data pointer function pointer.

i find myself putting (simplified) code in number of different javascript files: $(document).ajaxerror(function (e, xhr, settings, exception) { alert('error in: ' + settings.url + ' \\n' + 'error:\\n' + exception + ": " + xhr.responsetext ); }); is there downside can think of putting in site.master file once have consistent solution errors?. if that, there anyway override behavior on specific page? use $(document).ajaxerror in site.master file. to override in specific instance, include error callback on individual ajax calls, this: $.ajax({ url: '/yoururl', success: function(result) { alert('it worked!'); }, error: function(xmlhttprequest, textstatus, errorthrown) { alert('your custom error message here.'); } }); for not want override, them omit error callback.
