let's take @ code: public class parentclass { public void foo(object o) { system.out.println("parent"); } } public class subclass extends parentclass { public void foo(string s) { system.out.println("child"); } public static void main(string args[]) { parentclass p = new subclass(); p.foo("hello"); } } i expected print out "child", result "parent". why java call super class instead, , do make call method in subclass? subclass#foo() not override parentclass#foo() because doesn't have same formal parameters. 1 takes object , other takes string . therefore polymorphism @ runtime not applied , not cause subclass method execute. java language specification : an instance method m c declared in or inherited class c, overrides c method m a declared in class a, iff of following true: a superclass of c. c not inherit m a . the signature of

how can timestamp on file ( last access ) tried this: stat -c %x filename <br /> but doesn't work stat -c %x filename correct gnu stat. if you're on non-gnu platform (such macos), no format-string functionality may available; in case, might consider using different tool. (for instance, if have gnu find , -printf can used print atime). find filename -printf '%a@' ...is gnu find equivalent (if install on os x using macports, may called gfind ). if don't have either, i'd suggest perl if want portable alternative. note, way, it's common mount filesystems noatime improved performance (reduced overhead updating metadata); thus, may access time unavailable.

is there method in ruby allows breaking integers 1s, 10s, 100s, 1000s, ...? i know can convert integer string , parse string values mentioned above, imagine there simple way ruby other things. far have this: 1234.to_s.chars.reverse.each_with_index .map{|character, index| character.to_i * 10**index } # => [4, 30, 200, 1000] but there specific in ruby? you follows: n = 1020304 math.log10(n).ceil.times.with_object([]) |i,a| n, d = n.divmod(10) << d * 10**i end #=> [4, 0, 300, 0, 20000, 0, 1000000] hmmm. looks bit odd. maybe better return hash: math.log10(n).ceil.times.with_object({}) |i,h| n, d = n.divmod(10) h[10**i] = d end #=> {1=>4, 10=>0, 100=>3, 1000=>0, 10000=>2, 100000=>0, 1000000=>1}

i want make application run web application or desktop application, know how implement web server using django or flask, prefer django, there way port desktop application too? found nodewebkit maybe give me solution but, don`t have idea on how use it. import wx wx.lib.iewin import iehtmlwindow = wx.app(redirect=false) f = wx.frame(none,-1,"my desktop application") browser = iehtmlwindow(f) browser.navigate("http://google.com") f.show() a.mainloop() is pretty way remote web page pretend windows application ... assuming thats asking for.. (this uses wxpython of coarse need install it)

i trying track position of 'mybox,' @ time of click. works when attach event mybox, isn't want. want able click anywhere within window. thought since scene has .onreceive() function, able attach click event scene itself, whenever do, box not appear.

i have angular controller connected node/express server. response data request called in $http.get can set response=$scope.x . x can interacted , changed. set $scope.y = $scope.x , , changes y result in x changing well. however, want clone response have original response data set different variables without them changing each other. consider response response.name = "joe" . $scope.x = response; $scope.y = response; in code or view/model change x.name such: $scope.x.name = "bob" however, $scope.y.name still equal "joe" . i use 2 separate requests retrieve same response, i'd pass response function dynamically change data , make new version of based on for loop. there clean, "angular" this? or simple javascript function? angular has built in utility angular.copy() $scope.x = response; $scope.y = angular.copy(response); can used clean out unwanted properties angular can create such hashkeys used in ng-repeat t

i have 2 tables "category" , "publication" 1 many relationship. category: id, name, description publication: id, title, content, category_id and need category id through select element , put in category_id field. publication form: <form> <input type="text" ng-model="publication.title" placeholder="title" /> <input type="text" ng-model="publication.content" placeholder="content" /> <!-- here problem because can list categories can't category id , put in category_id field --> <div ng-init="categories()"> <select class="form-control" ng-model="category" ng-options="category.name category in categories"> <option value="">-- select category --</option> </select> </div> </form> this controller categories: $scope.categories = function() { $http(

i've noticed edittext fields in app not show selection anchors correctly. example: however, expect correct anchors appear such as: a typical example of affected edittext in app: <edittext android:id="@+id/text_message" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_toleftof="@id/button_send" android:layout_marginleft="@dimen/activity_horizontal_margin" android:paddingtop="@dimen/activity_vertical_margin" android:paddingbottom="@dimen/activity_vertical_margin" android:inputtype="text|textshortmessage" android:layout_marginright="4dp" android:hint="@string/hint_chat_send" /> also notice "paste" hover view has strange white border around in app, in other apps transparent. i suspect kind of theme issue, since affects multiple screens in app, cannot find info on attributes

i'd know when given user last logged in. seems user object doesn't include information (creation , modification only). should leverage events api (seems inefficient) or missing obvious? yes, events api this. specifically, you'll want use enterprise events api , query events of type login . requires access token administrative privileges. curl https://api.box.com/2.0/events?stream_type=admin_logs&event_type=login \ -h "authorization: bearer access_token" note that: the returned events paged, may need adjust page size or execute multiple queries find event(s) you're looking for. you can use created_after , created_before query parameters limit returned events specific time period. you can failed_login events: event_type=login,failed_login

say have 2 arrays of double precision in matlab, how can merge them unknown offsets? for example: a = 1 1 2 2 3 3 4 4 5 5 b = 2 6 3 5 4 4 5 3 6 2 is there way create these 2 arrays single array 3 columns below when don't know offset/overlap between , b in terms of values in first column? c = 1 1 nan 2 2 6 3 3 5 4 4 4 5 5 3 6 nan 2 is there efficient way this? the solution i've come right piece first columns of , b, , proceed use loop iterate through. a combination of union unique elements ismember find corresponding locations trick. as note, allow a , b have number of columns 2 or greater. a = [1 1;2 2;3 3;4 4;5 5]; b = [2 6;3 5;4 4;5 3;6 2]; %get elements first columns of , b c = union(a(:,1), b(:, 1)); %prepopulate c correct size nan's c = [c, nan(size(c,1), size(a,2) + size(b,2) - 2)]; %find rows of c column 1 of ended [~, i] = ismember(a(:,1), c(:,1)); %stick rest of in rows in first set of free columns c(i, 2:size(a,2)) = a(:,2:end

i'm sending encrypted data client through web service. the client had requested encrypt data using given key , iv. know should ideally use different random iv each time, , i've raised them. the iv have provided string of length 25. doesn't seem right me. as far aware iv length should match block size, either 128, 192 or 256 bytes (string lengths 16, 24 or 32). right, or missing here...? please note iv provided me, , therefore not trying pick it. the provided iv of form "ghpnhfg544judfjdr5bgvbj67", not believe correct.

please bear me have been reading , trying understand http , different requests available in protocol there still few loose connections here , there. specifically, have been using apache's httpclient send requests, i'm unsure of few things. when make request uri, how can know before hand how format put request? might trying transmit data fill out form, or send image, etc. how know if server capable of receiving format of request? if try put without knowledge of server request "fail" (or not - depends on implementation e.g. can redirect main page). failure indicated server response code along headers. e.g. 405 method not allowed or 400 bad request etc. or redirect main page: 302 found you, client, must adapt server's api. moreover different requests same api may give different specs e.g. 1 response gzipped & etag & cached, other 1 not. or plain get / give html , get /?format=json give json.

so, i'm making application , want gradually (over course of few seconds) shrink image control until disappears. so, bound scaletransform doubleanimation, happens instantly. here code: doubleanimation anim = new doubleanimation(360, 0, (duration)timespan.fromseconds(1)); scaletransform st = new scaletransform(); st.scalex = 0; st.scaley = 0; pacscore.rendertransform = st; anim.completed += (s, _) => exit_pacs(); st.beginanimation(scaletransform.scaleyproperty, anim); this should trick: doubleanimation anim = new doubleanimation(1, 0,(duration)timespan.fromseconds(1)); scaletransform st = new scaletransform(); control.rendertransform = st; st.beginanimation(scaletransform.scalexproperty, anim); st.beginanimation(scaletransform.scaleyproperty, anim);

i have been playing assembly recently, , when trying use div instruction, coming across floating exception . have searched online past day or 2 , nothing working. saw this question , , because of answer, put in 3 xorq instructions 0 out registers (specifically rdx because high byte of dividend), still didn't help. when compiling c program modulus operation (and creates few variables compiler doesn't optimize away modulus) using gcc -s myprog.c , gcc creates assembly file has cltd (convert signed long signed long double) instruction right before idivl . tried in program well, change anything. have tried using different size values in rax ans rbx , still doesn't work. question: doing wrong, , weird quirks there using div instruction? this documentation have been using learning assembly. in code below, function print prints contents of rax . don't care gets printed, printed can see instruction crashes program. .cstring _format: .asciz "%d\n"

so, i've been working on small project, nothing extensive. i've been having trouble understand why function in anonymous object isn't accessible on main script. alright "initializer", or script loaded before crucial operations, instantiates anonymous object accessed across entire scope of project. <?php class t_empty { public function __call($method, $args) { if(isset($this->$method) && is_callable($this->$method)) { return call_user_func_array( $this->$method, $args ); } } } $scope = new t_empty; $scope->config = array( 'path' => $_server['document_root'], 'loct' => '*' ); set_include_path ( $scope->config['path'] ); $scope->controller = $scope->service = $scope->service->injector = new t_empty; // #

i need figure out how make regex allow match correctly each time type number/decimal point. want limit number of digits before , after decimal point, isnt hard cant figure out how allow decimal point match well. 1 - match 12 - match 1234 - match 12345 - wrong 1234. - match 1234.1 - match 1234.12 - match 1234.123 - wrong other matched numbers 12.12 1.0 123.99 edit: so want max of 4 numbers before decimal place , 2 after. decimal place optional. the tricky part want fail if fifth character isn't decimal point. you need specify constraints better; i'm assuming want maximum of 4 before dot , 2 after: /^\d{1,4}(\.\d{0,2})?$/ edit: added beginning , end of string matchers. should work want now
