i have many sections and accordingly have different code maintained in html files home.html , about.html , want make angular custom directive render @ runtime and had tried making directive works first time not when using multiple times . need making directive app.directive('mysection', function() { return { restrict: 'e', transclude:true, templateurl: function(elem,attrs) { return "sections/"+attrs.templateurl +".html" } } }); and in html writing <mysection template-url="headersection"><mysection> <mysection template-url="headersection"><mysection> try markup <mysection template-url="headersection"></mysection> <mysection template-url="headersection"></mysection> note close tag

i have following class: public class x { public void a() { b(); } private static void b() { system.out.println("111111111"); } } now have following inherited class z: public class z extends x { private static void b() { system.out.println("22222222"); } } now if do z myclass = new z(); z.a(); i get: 111111111 result. (also, eclipse tells me b() in inherited class never called). why? , how can run inherited b method? the b methods static . when call method a uses implementation of class b (because that's method a defined). class b not aware of existence of class z , cannot call method of class z . because method static, it's not overridden upon inheriting b . polymorphism works instances of class. static method not play polymorphism game , cannot overridden.

in org-mode, there way keep higher level headings (superheadings, ancestors) visible move around buffer? i have structure lots of headings @ same level , i'd keep higher level headings contain them, scrolling off top of window move point down list. maybe horizontal split, point in lower window, , point's 'lineage' of headings in window above. the built-in which-function-mode display name of "function" in mode line. org-mode level 1 headline. if want full lineage can add function which-func-functions change how which-function determines function name.

the pictures show graph of nodes arranged pixel grid straight rows , columns. every node (except ones on edge) have 8 edges, go closest 8 nodes around it. picture on right shows a* search simple distance travelled + euclidean distance goal heuristic. now, path given picture on right isn't enough. instead want path if connect start node , goal node shortest possible string. algorithm getting called? finding euclidean shortest paths based on 2d grid discretization of traversable space can performed theta* algorithm. the other (more commonly employed) approach based on standard 4-way or 8-way pathfind (the picture on left), followed "string pulling" optimization. common algorithm known "funnel algorithm" . note neither of these approaches guaranteed produce globally shortest path. also, these assume you're set on representing world grid; if instead represent set of convex polygons, other algorithms more appropriate.

i have following function: //function random number public static int randomnumber(int min, int max) { random random = new random(); return random.next(min, max); } how call it: byte[] mac = new byte[6]; (int x = 0; x < 6; ++x) mac[x] = (byte)(misc.randomnumber((int)0xffff, (int)0xffffff) % 256); if step loop debugger during runtime different values (which want). however, if put breakpoint 2 lines below code, members of "mac" array have equal value. why happen? every time new random() initialized using clock. means in tight loop same value lots of times. should keep single random instance , keep using next on same instance. //function random number private static readonly random random = new random(); private static readonly object synclock = new object(); public static int randomnumber(int min, int max) { lock(synclock) { // synchronize return random.next(min, max); } } edit (see comments): why need lock her...

i believe have enough memory (16g) allocation in ubuntu (64 bit application). still return null. following memory information running free command. total used free shared buffers cached mem: 16376100 3295024 13081076 41936 88852 1073808 -/+ buffers/cache: 2132364 14243736 swap: 15998972 0 15998972 screenshot: based on comment, figured out. that's because when calculate memory size, sum overflowed. another case use int n_dataset = 2453688725; overflowed, n_dataset negative number.

i new ios, trying create scrollable custom view. basically on tapping on of icons in screen, custom view should pop botton. should have button expand full screen or on pan gesture should expanded full screen. here created wf better understanding. enter image description here edit: changed cutom view action sheet in question. action sheets don't have level of customization. you'll have make custom view functionality.

i hit issue iframe sandboxing behaved differently in firefox vs chrome getusermedia() , , while trying figure out, read https://developer.mozilla.org/en-us/docs/web/html/element/iframe , matched firefox's behavior. couldn't find equivalent documentation chrome, had experiment until worked. does google/chrome have such documentation? the short answer no. you can find useful information on https://developers.google.com/web/updates/ , although it's more of blog new chrome features (and deprecations), rather approaching comprehensive, organized documentation. https://developer.chrome.com/home links https://www.html5rocks.com/ , https://webplatform.github.io/ under "open web docs". the former again more of blog/magazine have useful articles, such https://www.html5rocks.com/en/tutorials/security/sandboxed-iframes/ (although didn't answer original question). the latter has been discontinued on year.

i tried deploy tutorial: tour of heroes heroku, answers found use angular2 seed, angular2 webpack or angular2 cli. tried of them , still can't figure out how deploy it. can give me detailed instruction of deploying angular 2 app? thank you. there's 1-click deploy on angular universal starter project. i tried clone , re-deploy , got stuck because need set config vars npm_config_production=false i'm still struggling how deploy production build vs. development build, it's example thats , running

logback's xml configuration allows define variables in external resources <property resource="foo.properties" /> spelled out in http://logback.qos.ch/manual/configuration.html#variablesubstitution . i'm in process of converting logback configuration in groovy (i.e. logback.xml -> logback.groovy) , not finding easy way achieve this. i able achieve same behavior normal java/groovy code properties props = new properties(); props.load(new fileinputstream("foo.properties")) def filepath = props.getproperty("filepath) but have hoped logback have supplied shorthand in form of logback-specific extension. does know of shorter way of accessing variables defined in external files , resources? besides this, i'm finding groovy configuration approach more concise , intuitive xml, , appreciate chance avoid dealing xml.

i learning use ggvis , wanted understand how create equivalent histogram produced hist. specifically, how set bin widths , upper , lower bounds of x in ggvis histograms? missing? question: how ggvis histogram output match hist output? let me provide example: require(psych) require(rcurl) require(ggvis) if ( !exists("impact") ) { url <- "https://dl.dropboxusercontent.com/u/8272421/stat/stat_one.txt" mycsv <- geturl(url, ssl.verifypeer = false) impact <- read.csv(textconnection(mycsv), sep = "\t") impact$subject <- factor(impact$subject) } describe(impact) hist(impact$verbal_memory_baseline, main = "distribution of verbal memory baseline scores", xlab = "score", ylab = "frequency") ok, lets try , reproduce ggvis... output not match... impact %>% ggvis( x = ~verbal_memory_baseline, fill := "white") %>% layer_histograms(width = 5) %>% add_axis("x", ti...

i running pyspark , spark 1.3 , standalone mode , client mode . i trying investigate spark job looking @ jobs past , comparing them. want view logs, configuration settings under jobs submitted, etc. i'm running trouble viewing logs of jobs after context closed. when submit job, of course open spark context. while job running, i'm able open spark web ui using ssh tunneling. and, can access forwarded port localhost:<port no> . can view jobs running, , ones completed, this: then, if wish see logs of particular job, can using ssh tunnel port forwarding see logs on particular port particular machine job. then, job fails, context still open. when happens, still able see logs above method. but, since don't want have of these contexts open @ once, when job fails, close context. when close context, job appears under "completed applications" in image above. now, when try view logs using ssh tunnel port forwarding, before ( localhost:<por...

i want extract data large xml, ex. via xpath, , process (data select, grouping). simpler way, described in this question ? ex., via apache avro? or, maybe, better in pig ?

i trying refactor existing code into more monodic approach . existing code contains interfaces ixinterface , numerics int , bool . numerics have zero default, interfaces have property gettor, bool , string not. 1 way out wrap bool , string in interface, cumbersome. i figured if f# language manages extend types numerics, perhaps can strings , bools particular situation. module myzero = let inline get_zero () : ^a = ((^a) : (static member get_zero : unit -> ^a)()) type system.string static member get_zero() = system.string.empty type xr<'t when 't : (static member get_zero : unit -> 't)> = | expression of (someobj -> 't) | action of (int -> 't) | value of 't | empty member inline this.execute(x: someobj) : 't = match | value(v) -> v | expression(ex) -> ex x | action(a) -> x.getlocation | empty -> get_zero() static member map f x= ...

i have written following function sync input fields: $(".dp1").on('change', function(e){ var datevalue = $($(this)[0]).val(); $.each($('.dp1'), function(index, item){ $(item).val(datevalue); }); }); $(".dp2").on('change', function(e){ var datevalue = $($(this)[0]).val(); $.each($('.dp2'), function(index, item){ $(item).val(datevalue); }); }); $(".rooms").on('keyup', function(e){ var datevalue = $($(this)[0]).val(); $.each($('.rooms'), function(index, item){ $(item).val(datevalue); }); }); $(".persons").on('keyup', function(e){ var datevalue = $($(this)[0]).val(); $.each($('.persons'), function(index, item){ $(item).val(datevalue); }); }); as function exact same 1 every time, guess there better way combine one. thinking of like my_custom_function(my_custom_value){ var datevalue = $($(this)[...

i have logging server receives data stateless clients on single network (inaccessible outside world). i'd make sure logs received server, if internet connection goes down. to easiest solution set proxy server, , have client log both logging server , proxy server. proxy server tries log logging server, , if fails caches request later. this: notes: all requests idempotent. the clients stateless (logs can not cached on clients) all parts of system, except intermediate "internet" step, configurable. the proxy server not need read or modify data. the logging server response not used client. i cannot make significant changes client or logging server (cassandra great application, though). my questions: there off shelf software can serve proxy? if not, think when writing this? there concerns scheme? your proxy looks simple persistent queue. have add/configure connector logging server. but without queue whole process looks 2 db queries , and 2 rest...
