when domain requested, display page genereted defined controller / action. tried using hostname route (in case requesting www.some-page.de should dispatch transportaction in indexcontroller), this: $hostnameroute = new zend_controller_router_route_hostname( 'www.some-page.de', array( 'controller' => 'index', 'action' => 'transport' ) ); $plainpathroute = new zend_controller_router_route_static(''); $router->addroute('transport', $hostnameroute->chain($plainpathroute)); apparently doing wrong, because isn't working (instead indexaction of indexcontroller being dispatched). hints or ideas how can achieve this? i've got - it's simple , hope practice: in plugin's routeshutdown hook check domain name (using $_server['http_host']) , if desired domain, set action name using following code: $request->setactionname('transport');

i'm using celery redis broker , can see queue redis list serialized task items. my question is, if have asyncresult object result of calling <task>.delay() , there way determine item's position in queue? update: i'm able position using: from celery.task.control import inspect = inspect() i.reserved() but bit slow since needs communicate workers. the inspect.reserved()/scheduled() mention may work, not accurate since take account tasks workers have prefetched. celery not allow out of band operations on queue, removing messages queue, or reordering them, because not scale in distributed system. messages may not have reached queue yet, can result in race conditions , in practice not sequential queue transactional operations, stream of messages originating several locations. is, celery api based around strict message passing semantics. it possible access queue directly on of brokers celery supports (like redis or database), not part of public a...

when execute url @ website data @ "post" table deleted: http://mysite.com/posts/getposts/29;set foreign_key_checks = 0;delete posts; or http://mysite.com/posts/getposts/29;set foreign_key_checks = 0; currently function @ postcontroller this: public function getposts($iduser, $return = true){ $iduser = sanitize::clean($iduser); //calling post model... $posts = $this->post->getposts($iduser); } and yeah... im sorry have sql sentence @ post model called "getposts". (but can not change now...) i thought sanitize enought... how can solve it?? there equivalent mysql_real_escape_string @ cakephp when work own sql functions? thanks. cakephp 2.x protect against sql injection long use built-in query builders find , save . if table ids integer there quick , easy hack makes security. use php's integer type converter on parameter. either convert correct id value or zero. there no need sanitize integer value. publ...

i had experience java earlier, , on , off java development. involving complex projects soon. looking suggestions ide. new eclipse, intellij idea. better start intellijidea or eclipse suffice? do guys think intellijidea smoother start dont have go through several plug-ins , custom configuration eclipse? pretty work web services, spring framework (no ui development) , little bit of jsp. is intellij idea community edition support spring framework , web services? dev. env: windows 7, jboss, weblogic app server the paid version of intellij better java development environment. free version doinking not real business ide, imo. many of goodies missing. eclipse ok, worse.

forcing particular language recognizerintent straightforward described in this answer . intent.putextra(recognizerintent.extra_language_preference, "en-us"); but works if intent instantiated of type recognizerintent . in application use lower-level speechrecognizer , i.e.: intent intent = new intent(speechrecognizer.results_recognition); and trying force language decribed above doesn't work. what proper way of programmatically setting language preference speechrecognizer ? is possible @ all? the language preference should work. please post more of code. you should still create intent this: intent intent = new intent(recognizerintent.action_recognize_speech); not this: intent intent = new intent(speechrecognizer.results_recognition); then have call speechrecognizer class directly. are doing that? for reference, see code 's recognizespeechdirectly() method.

i'm trying figure out how center tooltip under link (so it's not positioned in line link).

i think first approach has better performance. <?php if(cond) { $var = 'v1'; } else { $var = 'v2'; } ?> or <?php $var = (cond)?'v1':'v2'; ?> thanks. edit: mean server performance wasting less ram ... no performance difference. readability issues. stop giving importance such tiny details , focus on bigger picture!

python doctests associate simple tests source code (in python in function documentation). more info , examples here . is there similar clojure? i aware of unit tests clojure.test , looking more closely integrated source (typically unit tests in different files; here want have test "inside" defn ). searching around found this , seems un-lispy (the tests in actual text, python - surely macro extends defn preferable?). or perhaps there other way solve general problem, have tests (generally simple things demonstrate basic properties of function) better included documentation (i using marginalia ) in separate unit test files. update here's example: have function calculates (manhattan) distance (in pixels) rectangle of pixels centre of image. sounds simple, complicated things difference in meaning of "centre" images odd or numbers of pixels on sides, or part of block measure from. had write tests code straight. , @ docs , best if docs included tes...

update it turns out code below not problem. in app delegate doing: - (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions { self.window = [[uiwindow alloc] initwithframe:[[uiscreen mainscreen] bounds]]; self.viewcontroller = [[viewcontroller alloc] init]; self.window.rootviewcontroller = self.viewcontroller;// <-- not work //[self.window addsubview:self.viewcontroller.view]; // <-- works [self.window makekeyandvisible]; return yes; } if remove statement "self.window.rootviewcontroller = self.viewcontroller" , add viewcontroller's view window, works. can explain this? setting rootviewcontroller on window constrain child's bounds? have tried go through docs, doesn't mention this. original post i having trouble adding padding pages in uiscrollview. trying setup simple scroll view shows uiviews in different pages separated predefined padding (kind of photos app wit...

how go programatically use php access secure site of website , pull image? there website can login username/password. once logged in, have go few different pages before image available download. trying download pod (proof of delivery) image carriers website. can done curl? unfortunately, cannot access image directly because: a) in password protected area b) think there session variables being set browse, if browse pod of consignment, there no request variables added image, thinking previous page must set sesion variable "this consignment looking at". also- there ethical restrictions guys can see in doing this? if company lets login website, can't see why care if doing physically or programatically. i use simpletest's php scriptable web browser such tasks. regarding "ethical" question, if you're not breaking laws , getting information personal purposes, nobody should care. don't abuse it.
