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.

i'm trying load 3d model three.js jsonloader , , 3d model in same directory entire website. i'm getting "cross origin requests supported http." error, don't know what's causing nor how fix it. my crystal ball says loading model using either file:// or c:/ , stays true error message not http:// so can either install webserver in local pc or upload model somewhere else , use jsonp , change url http://example.com/path/to/model

i want grant update privileges user tables within schema except update primary keys. there easy way it? or should separately each table , define each column. how work? im sure there easy way it. i'm reading documentation gives me generic examples. declare myquery varchar2(1024); begin rc in (select * user_tab_cols u not exists ( select * user_constraints c ,user_cons_columns cc c.constraint_type = 'p' , c.constraint_name = cc.column_name , u.table_name = cc.table_name , u.column_name = cc.column_name )) loop myquery := 'grant update ('||rc.column_name||') on '||rc.table_name||' myuser'; --dbms_output.put_line(myquery); execute immediate myquery; end loop; end; p.s. i'm not sure "all tables" in description means . in query tables within current schema, if need tables within database change user*** all***, i.e. user_constraints all_constraints, etc

currently, junit 5 out "stable" version. intellij supports junit 5 according website. question if eclipse supporting junit 5 well, , if not when going supported. supported mean if can run junit 5 tests without need @runwith(platformrunner.class) annotation. edit october 2017: eclipse officially supports junit 5 of eclipse oxygen1.a (4.7.1a) you can run junit 5 tests in eclipse 4.7 oxygen after installing junit 5 support (beta) oxygen 4.7 plugin can find in eclipse marketplace. after complete eclipse restart, open project properties at java build path -> libraries -> add library -> junit -> junit 5

i'm having trouble creating dedication appid watch extension. so far app , corresponding watch app worked perfectly. had app id configured using bundle id similar following format: xx.yyyyy.appname , , watchkit app & extension using wildcard appid relevant (and suggested) bundle id of xx.yyyyy.appname.watchkitextension , xx.yyyyy.appname.watchkitapp , great. i found out need change current behaviour of apple watch app share data parent app, , in order had enable app groups capabilities, found i'm not able watchkitextension (apparently app group capabilities required explicit app id rather wildcard app id). realising don't have dedicated app id went member centre , tried make 1 unsuccessfully. following apple's guidelines i'm trying create app id same prefix of xx.yyyyy.appname following .watchkitextension . this results in following error message: an app id identifier 'xx.yyyyy.appname.watchkitextension' not available. please enter

i have following structure: std::map<int, std::map<int, int>> my_map; i want check whether key my_map[3][5] exists. is there easier/shorter way except like: if (my_map.find(3) != my_map.end()) { std::map<int, int>& internal_map = my_map[3]; if (internal_map.find(5) != internal_map.end()) { // ... ... } } you improve little via: std::map<int, std::map<int, int>>::iterator = my_map.find(3); if (it != my_map.end()){ if (it->second.find(5) != internal_map.end()) { } } in current solution, finding key twice , slower finding once , store in iterator.

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 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 had subroutine code (see below) working fine until hour ago while testing. notifyofpropertychange(() => testresults); triggers error: "cannot convert lambda expression type 'string' because not delegate type" i have googled around, , solutions suggest adding "using system.linq". have done "using system.data.entity". both of these greyed out in visual studio suggesting not used, , error still persists. i'm new using wpf linked subroutines, i'm not entirely sure doing, said been working fine, , have similar program there no error. both have same references , usings, , other program doesn't have "using system.linq" i'm sure stupid i'm missing. thanks public string testresults { { return _testresults; } set { _testresults = value; notifyofpropertychange(() => testresults); } } looks implement interface inotifypropertycha

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
