i using datatables.js jquery plugin. the first column of table row counter, don't want sortable user. last column contains action link user can perform on row. how can make these 2 columns unsortable? note: using pipeline (server-side process) mode of datatables. this done setting bsortable false: /* using aocolumndefs */ $(document).ready(function() { $('#example').datatable( { "aocolumndefs": [ { "bsortable": false, "atargets": [ 0 ] } ] } ); } ); /* using aocolumns */ $(document).ready(function() { $('#example').datatable( { "aocolumns": [ { "bsortable": false }, null, null, null, null ] } ); } );

i have instance of mpmovieplayercontroller being used display live streaming video on iphone app. working fine, wish remove airplay functionality. to sure, disable airplay so: if([self.movieplayercontroller respondstoselector:@selector(setallowsairplay:)]) { self.movieplayercontroller.allowsairplay = no; } however, code, still see airplay icon on video controls. if select this, , select appletv, audio sent on airplay - video continues play within app. if set allowsairplay yes , both video & audio sent on airplay. does know why happens? feature of os, allows allow audio sent on airplay? it turns out airplay icon still visible (and should remain visible) audio can routed suitable device, eg. bluetooth headset. attempting hide icon considered bad practice.

i plan use json data in both request , response in project , having problems in testing. after searching while, find following code uses curl post json data: curl -h "content-type:application/json" -h "accept:application/json" \ -d '{ "foo" : "bar" }' localhost:3000/api/new in controller can access json data using params[:foo] easy. functional testing, find post , xhr (alias xml_http_request ). how can write functional test in rails achieve same effect using curl ? or should test in other ways? here's i've tried. find implementation xhr in action_controller/test_case.rb , , tried add jhr method changing 'conetent-type' , 'http_accept'. (added in test/test_helpers.rb .) def json_http_request(request_method, action, parameters = nil, session = nil, flash = nil) @request.env['content-type'] = 'application/json' @request.env['http_accept'] ||= [mime::json, mime::js,...

i perform selector in application: - (void) dofilter:(uibutton*)button { [activityindicator startanimating]; [self disablebuttons]; // ... // actions // ... sleep(2); [self enablebuttons]; [activityindicator stopanimating]; } when user clicks on button. activityindicator uiativityindicatorview. don't see activity indicators while code performing. how can fix it? firstly, should never ever use sleep on main thread. blocks entire app , user can't time. secondly, ui not updated until code returns control run loop. whenever call startanimating , stopanimating in same method without returning run loop in between, can sure nothing happen in ui (same disablebuttons , enablebuttons ). solution: call startanimating , disablebuttons . start tasks have perform in background ui not blocked. can use nsoperation , performselectorinbackground:... , grand central dispatch etc. that. finally, when long task finished, have call m...

specifically there risk data can lost? i'm looking @ running intensive transaction processing system critical nothing lost. there examples of nosql being used in mission critical applications such banking transaction processing? without being flippant, absence of acid means no guarantees of atomicity, consistency, isolation, or durability. without atomicity, no guarantee multiple actions must either succeed or fail so. instance, if transactions require debit 1 account , credit in 1 go, in absence of atomic transactions, either have roll own solution, or accept it's possible debit 1 account, without making corresponding credit. without consistency, there's no guarantee "side effects" of transactions work - in relational databases, that's things firing of trigger, or cascading of foreign key relationship. so, if need kind of auto-incrementing unique identifier transaction, there's no guarantee one. without isolation, there's no way g...

i perform post-order tree traversal in c++. tree can deep cannot use recursion (it exhausts stack). instead create std::stack<...> puts on heap, , traverse tree in while loop rather function calls. works great. now parallelize whole process using tbb. thinking of creating task_group @ every node, , running same functor on each of children. occurs me run same problem tree depth had before: running functor on each node of deepest path eat away stack until whole thing runs out. is there way out of problem? or imagining whole thing; there magic behind task_group::wait() avoids problem? from tbb documentation (about implicit continuation): because parent blocks, thread’s stack cannot popped yet. thread must careful work takes on, because continually stealing , blocking cause stack grow without bound. this not that, shows tbb not using stack magic empty stack blocked tasks. means stack-overflows bit later (spreaded among multiple thread's stacks...

i looking @ cqrs frameworks use project hosted in azure . i have read ncqrs , lokad.cqrs , little bit confused. will both work azure, both capable of using nservicebus or lokad use own messaging? the clients use both web , mobile. thought of making wcf service commands, not sure wcf. any recommendations? lokad.cqrs designed work azure start. uses azure queues messaging (with azure blobs cases, when messages not fit in 8kb size limitation). i'm not sure ncqrs, might provide adapter lokad.cqrs.

for quiet sometime have been working on improving algo skills because requirement clear interviews in companies google, amazon etc. came across questions on object oriented programming concepts being asked in amazon interviews. being programmer in c doesn't know oops. sort of books, links improve these skills appreciated. in advance. i started first edition of tim budd's "an introduction object-oriented programming". language agnostic, learned concepts, not implementations. the third edition out.

i needed add shutdown hook scala app have, , discovered scala provides helper called shutdownhookthread . in source noticed it sets new thread daemon thread . def apply(body: => unit): shutdownhookthread = { val t = new shutdownhookthread(hookname()) { override def run() = body } t setdaemon true // <--------- right here runtime addshutdownhook t t } why done? seems me you'd want opposite in shutdown hook thread (i.e. make sure thread exits before shutting down jvm). or daemon/not-daemon not relevant shutdown hooks? on jvm, in general non-daemon thread prevent jvm terminating. once there no longer non-daemon threads, jvm gracefully terminate initiating shutdown. see addshutdownhook javadoc more info. once shutdown has been initiated, i'm not sure daemon status matters. shutdown hook threads aren't started until shutdown has been initiated. in case t setdaemon true may unnecessary, won't hurt either. so in short "daemo...

since firefox open source, in theory should possible me hack behavior of interpreter. let's maybe build own profiler, or introduce more fine grained restrictions on javascript behavior , not allow in browser. or something, whatever... so how easy sort of thing in practice? achieved through sort of plugins? or need recompile interpreter source? or recompile entire browser? how big interpreter source anyway? hard thing grok has built toy compilers in college? if restrict interpreter, things not bad. if want deal 2 jits well, it's more work. in terms of codesize, looks we're talking 180k lines of code (headers , c++ files), not counting regexp engine , jits. understanding interpreter not bad; 1 thing there's bit of documentation @ http://developer.mozilla.org , people on #jsapi channel on irc.mozilla.org happy answer questions. something profiler need hack source if want profile without perturbing system much. experiments in terms of supported fe...

i'm using lighttpd web server , have install wordpress run blog. i concerned caching. know there module php named xcache don't understand if have install module or install " super cache " wordpress plugin. what differences? can run together? thank you! xcache opcode cache. php compiles every time run. xcache cache code in machine language , store in ram. speed execution of script doesn't need recompiling , stored in ram (less i/o). however, means pages still dynamic, means pages generated everytime executing php code on there. if install super cache plugin, cache html of page. store html , serve user. means data static caching time , not dynamically generated every user. it best use both maximum performance results. need xcache installed on server able use xcache plugin in wordpress.
