i new ror , don't understand how can make global template put in other template. example have categories module , create sidebar navigation , put @ homepage template. tried way, categories controller method side_nav never called. practice type of problem or should different way? categories/categories_controller.rb def side_nav @categories = category.all end categories/_side_nav.html.erb <ul class="list-unstyled"> <% categories.each |category| %> <li><%= link_to category.title, category.title.downcase %></li> <% end %> </ul> homepage/index.html.erb <%= render 'categories/side_nav' %> you may @ layout/application file. it's global layout in custom project default. , can provide custom layouts in contollers. http://guides.rubyonrails.org/layouts_and_rendering.html

as heading states: can wireshark display info size of data in http post request? it better if see size of specific fields submitted in post data. how/can achieved? can wireshark display info size of data in http post request? if "data" mean posted data, then, if post request has content-length: header, yes, can - header. it better if see size of specific fields submitted in post data. that's not easy, although can individual fields of "xxx=yyy" item "urlencoded-form.key" , "urlencoded-form.value" if content-type application/x-www-form-urlencoded.

i using overflow-scroll = "true" make ionic use native scrolling : <ion-content overflow-scroll = "true"> <ion-list> <ion-item ng-repeat="foo in bar"> {{foo.label}} </ion-item> </ion-list> </ion-content> this works great (performances good). problem (vertical) scrollbar disappeared. as per documentation , tried adding scrollbar-y="true" ion-content , didn't work. i tried adding css : ::-webkit-scrollbar { -webkit-appearance: none; } ::-webkit-scrollbar:vertical { width: 11px; } ::-webkit-scrollbar:horizontal { height: 11px; } ::-webkit-scrollbar-thumb { border-radius: 8px; border: 2px solid white; background-color: rgba(0, 0, 0, .5); } ::-webkit-scrollbar-track { background-color: #fff; border-radius: 8px; } ... didn't work either. this article (look "native scrolling") says problem can solved using css, though.

coming c# background, used interfaces base mock objects off of. created custom mock objects myself , created mock implementation off c# interface. how do in js or node? create interface can "mock" off of , interface serve real class able implement interface? make sense in js or or node world? for example in java, same deal, define interface method stubs , use basis create real class or mock class off of. unfortunately you're not going find standard interface part of javascript. i've never used c#, i've used java, , correct me if i'm wrong, looks you're talking creating interfaces , overriding methods both mock testing purposes, being able implement interfaces in other classes. because isn't standard javascript feature, i think you'll find there going lot of broad answers here . however, idea of how popular libraries implement this, might suggest looking @ how angularjs looks @ mock testing (there many resources online, google

i'm using couple of strings in code going reused within loop , i'm wondering best way initialize string variables improve memory usage: // sample purposes declare map, same thing // applies arraylist, database set, etc. point. map<string, string> samplemap = getmap(); int mapsize = samplemap.size(); // string initialization string a; string b = new string(); string c = ""; for(int = 0; < mapsize; i++){ = samplemap.get(i); b = somefunc(a); c = anotherfunc(a); // stuff strings } after loop, strings no longer used. you cannot optimize initialization or memory usage of strings in snippet of code, several reasons: java strings immutable - cannot change characters inside string, can point new string. in loop, called function (such afunc() or get() ) 1 responsible allocating string, not loop. for advanced programmers: if want optimize memory usage of strings, need use stringbuffer/stringbuilder or raw character array , pass

this not trivial question asked here in stackoverflow before, @ least haven’t found similar, of course googled , read of high ranked results. btw, if folks here don't feel comfortable objective c’ s block syntax, visit page please http://fuckingblocksyntax.com , before throwing block related issues. 1st part of question is: the background of declaration of block-parameter, invoking method has block-parameter ( in many cases, completionblock ) the “ callee-method " in myworker class: … ... @implementation myworker -(void) aworkermethodneedsablockinput: ((void)(^)( nsobject *, double )) blockparam { nsobject *anobj=[[ nsobject alloc] init]; double *adouble; [self retrievetimeconsumingresults: anobj withnumberoftry: adouble ]; blockparam ( anobj, * adouble ); } @end the “ caller-method " in mymanager class: @interface mymanager() @property (nonatomic) myworker * mworker; @property (nonatomic, copy) (void)(^mblockproperty)

i have requirement automate procedure on web page. open web page find input click on it close web page i achieve of above using c# in console application . dont want open browser, code automate process. i have url web page , id of input element. what c# code should use achieve this.? i think able serve purpose. selenium 1 (selenium rc) : selenium server launches , kills browsers, interprets , runs selenese commands passed test program , , acts http proxy, intercepting , verifying http messages passed between browser , aut. selenium server receives selenium commands test program, interprets them, , reports program results of running tests. the rc server bundles selenium core , automatically injects browser. occurs when test program opens browser (using client library api function). selenium-core javascript program, set of javascript functions interprets , executes selenese commands using browser’s built-in javascript interpreter. the server receives

i have part of marionette app opening bootstrap modal. when happens, want register opening "navigate" event, using app.navigate("/modal",false); change url. in modal view listening history event close modal (useful android / mobile), append "/modal" current route, instead of root. how can current route/url append "/modal" , call .navigate() function on? thanks! edit: apparently phrase looking here, in terms of web development, "micro-state", explained @ blog here: http://chrisawren.com/posts/implementing-microstates-in-backbone-js the approach suggested bypass backbone history altogether , directly interface html5 history stack, places need fullscreen modal don't want invoke router handling or change url, still want support button. simply router.navigate(router.fragment + "/modal")

i struggling optimization of displayed 3d object. want achieve make 3d spectrogram of audio file. what's more want have black , white , nice looking. nice looking means - this: this sample image - aware spectrogram won't that this code used generating surface reduced number of faces: [y,fs,nbits]=wavread('audio.wav'); [s f t]= spectrogram(y(:,1),256,100,256,fs); clear y [x,y]=meshgrid(t,f); z=log10(abs(s)); rskip = round(linspace(1,size(z,1),80)); cskip = round(linspace(1,size(z,2),64)); surf(x,y,z,'facecolor','white','edgecolor','none'); hold on surf(x(rskip,:),y(rskip,:),z(rskip,:),'facecolor','none','meshstyle','row'); surf(x(:,cskip),y(:,cskip),z(:,cskip),'facecolor','none','meshstyle','column'); hold off view(-65.5, 28); the main problem audio file , reason why using reduced number of faces size of x,y,z arrays - 129 269065. pc has 8gb of ram , around 1gb us

with new attribute routing , constraints seems border why should use attributes validate dto`s gets blurry more , more. i can range validation on 2 ways - consider first approach has action complex class + weight property - when should use approach , advantages vs other approach? [range(0,500)] public int weight {get;set;} vs [get("{id:range(0, 500)}")] public machine getmachine(int weight) { } the first approach result in bad request. the second approach result in not found request. your last 2 sentences summarize well. in case of [range] , sets validation of input can tell caller request bad. in second, it's defining rules matching url route, used sending requests different routes, not validating input. second useful, example, if have ids of different formats want handle different methods. in short, ux first "i must sending invalid data" , second "i must have wrong url." update : here's demonstration of meant ho

i have php helper class static methods. when add new method or make changes file , afterwards upload server, server not detect changes. error saying fatal error: call undefined method class::functionname() not exist even though exist. i've tried restarting apache server , clearing browser cache. don't have caching setup on server either. if can, connect server ssh , investigation. example, search php file find, see if lies around multiple times, check last modified dates, , of course contents. maybe modify main file of webpage (for example index.php ), verify looking in right place.

i have report add action drill through report. in target report, have multivalued parameter need pass 2 values to. them literals set, not user selectable or based off of tablix data, can't seem find way this. know =join(field!col.value, ","), have used great success, need pass set value of 8 , 3 recieved target parameter selection of id 8 (works on it's own) , value of 3, if use =8 , 3 or =8 or 3 or =8,3 pass both value parameter, either mathematically adds 2 (value of 11 passed across) or errors in syntax. there method of passing these 2 static values parameter in target report? was able resolve own problem. incredibly mess, modified dataset include fixed value , referenced in parameter split() function send across multiple values.
