i need create data field go through vector. data field constant length, , going through data vector shifting data field data field length. need mean value of field (a vector) corresponds mean value of field (b vector). example: a=[1 5 7 8 9 10 11 13 15 18 19 25 28 30 35 40 45 48 50 51]; b=[2 4 8 9 12 15 16 18 19 20 25 27 30 35 39 40 45 48 50 55]; i want next: a=[{1 5 7 8 9} 10 11 13 15 18 19 25 28 30 35 40 45 48 50 51]; b=[{2 4 8 9 12} 15 16 18 19 20 25 27 30 35 39 40 45 48 50 55]; i want take data field of 5 points , mean value. , shift whole data field data field length. a=[1 5 7 8 9 {10 11 13 15 18} 19 25 28 30 35 40 45 48 50 51]; b=[2 4 8 9 12 {15 16 18 19 20} 25 27 30 35 39 40 45 48 50 55]; i need 2 vectors, c , d mean values of method. c=[6 13.4 27.4 45.2]; d=[7 17.6 31.2 47.6]; i started with n = length(a); k = 1:n .... but nothing tried worked. thanks. reshape vector 5-row matrix , compute mean of each column: c = mean(reshape(a,5,[])

i search way display tooltip permanently, when tooltip shared. these points important: click on point --> tooltip cloned , displayed permanently click on same point again, clone removed multiple tooltips allowed displayed @ same time thanks. as sebastian pointed out in comment - clone tooltip. when tooltip has usehtml set false (by default does), need clone svg element. see similar topic: link when usehtml set true div element created , appended container of chart. need clone not svg frame, html's div. issue check cloned tooltips x, because tooltip shared. example: http://jsfiddle.net/7vkzv/14/ when usehtml true html overflow other svg elements - avoid style html div tooltip text , remove visible style in svg tooltip. in other words - make tooltip in pure html. example: http://jsfiddle.net/7vkzv/15/

i printing simple select list out looping through associative array populated elsewhere. <select id="choice" name="choice"> <?php foreach ($this->choice $key => $value) { echo "<option name=".$value." value=".$key.">" .$value.

i use handlebars-helpers node module handlebars templates. i'm using hapi framework supports handlebars. haven't found documentation or examples shows how use handlebars-helpers hapi using handlebars view engine. is possible , if so, solution? i don't think it's possible according hapijs api docs views: http://hapijs.com/api#serverviewsoptions helperspath - directory path helpers located. helpers functions used within templates perform transformations , other data manipulations using template context or other inputs. each '.js' file in helpers directory loaded , file name used helper name. files must export single method signature function(context) , return string . sub-folders not supported , ignored. defaults no helpers support (empty path). note jade not support loading helpers way. looks though handlebars-helpers has different signature required hapi

i working on little project , have dataset of 60k nodes , 500k relationships between nodes. nodes of 2 types. first type are recipes , second type ingredients. recipes composed of ingredients like: (ingredient)-[:is_part_of]->(recipe) my objective find how many common ingredients 2 recipes share. have managed obtain information following query compares 1 recipe others (the first 1 others): match (recipe:recipe{ id: 1000000 }),(other) (other.id >= 1000001 , other.id <= 1057690) optional match (recipe:recipe)<-[:is_part_of]-(ingredient:ingredient)- [:is_part_of]->(other) ingredient, other return other.id, count(distinct ingredient.name) order other.id desc my first question: how can obtain number of ingredients of 2 recipes in way mutual ones counted once (union of r1 , r2 --> r1 u r2) my second question: possible write loop iterate through recipes , check common ingredients? objective compare each recipe others . thin

i trying write webhook whenever specific command run in bash. example, when ls called, run script. more specifically, when command spark ran, want write slack channel using webhooks. put wrapper earlier in path. let's spark in /usr/bin . if users' paths have /usr/local/bin before /usr/bin , can in /usr/local/bin/spark : #!/bin/sh [ "${_spark_wrapper_done}" ] || send-to-slack-here "$@" export _spark_wrapper_done=1 exec /usr/bin/spark "$@" ...where send-to-slack-here , of course, code send message slack. you move /usr/bin/spark /usr/bin/spark.real , put wrapper in original executable's place. if control .bashrc , use shell function (though work in fewer scenarios): spark() { send-to-slack-here "$@" /usr/bin/spark "$@" }

there functions in stl start make_ prefix std::make_pair , std::make_shared , std::make_unique etc. why better practice use them instead of using constructor ? auto pair2 = std::pair< int, double >( 1, 2.0 ); auto pair3 = std::make_pair( 1, 2.0 ); std::shared_ptr< int > pointer1 = std::shared_ptr< int >( new int( 10 ) ); std::shared_ptr< int > pointer2 = std::make_shared< int >( 10 ); i see these functions make code little shorter, ? are there other advantages ? are these functions safer use ? aside benefit of enabling argument deduction (as mentioned in other answers), there other benefits. std::make_pair<t1, t2> takes care not return std::pair<t1, t2> . if pass in value using std::ref , returned pair won't store std::reference_wrapper , store reference. std::make_shared can combine allocations. shared_ptr needs place hold things refcount, weak pointer list, etc. cannot stored in shared_ptr directly. these

i using mvc 5 on .net , have user flow looks this: user enters address form. form gets posted controller using ajax. controller records address database. controller makes webclient request bing maps geocode address latitude , longitude. controller records latitude , longitude database. controller returns ajax result rendered client-side updated view address , latitude/longitude. i know call bing maps should happen in async context site's speed uncoupled of bing maps. instead think flow should work this: user enters address form. form gets posted controller using ajax. controller records address database. controller launches async task geocoding , update database controller returns ajax result client shows updated address , tells poll client-side completion of geocode result. i stuck on step #4. here have: public actionresult getlocation(int id) { listing li = db.listings.find(id); task.run(() => { // update geocode if necessary

i'm trying add textfield 'location' input uisearchcontroller when user focuses on search bar, below search bar on navigation bar. example of have , i'd go: i've tried this, doesn't work: var searchcontroller: uisearchcontroller! func searchbartextdidbeginediting(searchbar: uisearchbar) { var mytextfield: uitextfield = uitextfield(frame: cgrect(x: 0, y: 0, width: 200.00, height: 40.00)) mytextfield.backgroundcolor = uicolor.purplecolor() mytextfield.text = "location" mytextfield.borderstyle = uitextborderstyle.none searchcontroller.view.addsubview(mytextfield) } any great! thanks. don't know whether found answer or not. let me suggest solution. nothing wrong in code. works fine. reason why doesn't show , when click in search bar func searchbartextdidbeginediting(searchbar: uisearchbar) has no effect on because might forget set delegate search bar. i tried code , after setting delegate works fine.

this program prints "true" console. allocate object, make weakreference of that, go out of block scope, , check weakreference.isalive. public static void main (string[] args) { test (); } static void test () { weakreference wref = null; { // block scope var obj = new object (); wref = new weakreference (obj); } // obj out of scope // console.writeline (obj); gc.collect (); console.writeline (wref.isalive); // => true } why obj not collected, though obj out of scope? the program compiled mono 3.12.0. edit: sorry, inappropriate example. the following program print true. block scope seems not related. tried not debug mode. public static void main (string[] args) { test (); } static void test () { weakreference wref = null; var obj = new object (); wref = new weakreference (obj); obj = null; gc.collect (); console.writeline

i can't find how listarray variables androidjavaobject in c#. i'm trying make for function using count number of items in listarray stored androidjavaobject . need know how count androidjavaobject , how use properly. i'm using variables, notice "packages" not androidjavaobject[] . androidjavaclass jc = new androidjavaclass("com.unity3d.player.unityplayer"); androidjavaobject currentactivity = jc.getstatic<androidjavaobject>("currentactivity"); int flag = new androidjavaclass("android.content.pm.packagemanager").getstatic<int>("get_meta_data"); androidjavaobject pm = currentactivity.call<androidjavaobject>("getpackagemanager"); androidjavaobject packages = pm.call<androidjavaobject>("getinstalledapplications", flag); it's rudimentary @ point, works how installed apps list unity3d? the progress far stalls @ getting icon, else works perfect, need way either st

i'm working on express app created basic azure node.js express 4 application template in visual studio. in other words, it has web.config modifications necessary support express 4's www\bin structure . this app works fine when debugging via visual studio or running directly via node command line. however, deployments source control not work when hooked github repo. can see project root in site\wwwroot folder. more strange, publishing directly visual studio works. this turned out simple oversight, feel can trip others i'll share answer here. i'm using visual studio .gitignore file github , includes rule ignore [bb]in/ these build output. commits not including contents of /bin , continuous deployment wasn't picking these either. commenting out line fixed issue.

let's have global object that's accessible 1 function accepts string. the following defined inside function. function setitem(string, val) { var scope = [{ apple : true, test : 'aa' },{ apple : false, test : 'bb' }]; var obj = { 'deep' : scope } obj.string = val; return obj.string; }); now want first item, overwrite data. setitem('scope[0].apple', 'apple off' ); obviously above isn't going work when trying set variable, i'm wondering if there's way evaluate string value can contain dotnotated , index selectors? it can done eval . function setitem(string, val) { var scope = [{ apple: true, test: 'aa' }, { apple: false, test: 'bb' }]; var obj = { 'deep': scope } eval(string + ' = ' + json.stringify(val)); return eval(string); }; alert(setitem('scope[0].ap

i have listview containing textview click on. i have managed make this, no matter row's textview click on it's clicked on bottom row's. for example, when click on textview in row 2, acts if clicked on textview in bottom row of screen. it doesn't seem matter row's textview click on, it's if click on last loaded position's textview. from reading other related questions, googling, , running debugger, suspect has fact row on bottom of screen last position loaded , when click on uses positions clicklisteners. i've seen need make use of tags resolve this, couldn't quite understand how apply tags , how use tag's position in code. here custom arrayadapter's getview method , listeners: @override public view getview (int position, view convertview, viewgroup parent) { question = (question) getitem(position); // or create cached eventview if(convertview == null){ convertview = (linearlayout) inflater.inflate(mres

i've been working on wordpress theme integrated woo-commerce. while editing theme header section states "free shipping on orders above $75". wanted $100 , managed find information inside wp_options table in database. after editing text $100 header , footer sections won't show up. i know issue , why both of sections won't show up. the wp_options table contains theme (and plugin) settings stored user options in database. user data many times saved serialized data; format saves space. when directly edit , resave theme's data in wp_options phpmyadmin or adminer, breaking serialized data string, , result, break theme's settings. the database tools phpmyadmin or adminer not designed , have no way unserialize , reserialize editing. so don't edit theme options directly in wp_options unless absolutely necessary. make theme changes in theme's php code, in localization strings, in html, whatever. to header , footer back, resave t

i'm using postgrex in elixir, , when returns query results, returns them in following struct format: %{columns: ["id", "email", "name"], command: :select, num_rows: 2, rows: [{1, "me@me.com", "bobbly long"}, {6, "email@tts.me", "woll smoth"}]} it should noted using postgrex directly without ecto. the columns (table headers) returned collection, results (rows) returned list of tuples. (which seems odd, large). i'm trying find best way programmatically create json objects each result in json key column title , json value corresponding value tuple. i've tried creating maps both, merging , serialising json objects seems there should easier/better way of doing this. has dealt before? best way of creating json object separate collection , tuple? something should work: result = postgrex.query!(...) enum.map(result.rows, fn row -> enum.zip(result.columns, tuple.to_list(row)) |

i have huge data filet hat backend giving me.....i have forward same file other application ....could please suggest way go streaming or chunking if both different. and if both same thing have other option using http protocol. there no clear difference in performance between chunking , streaming . advantage of streaming might : streaming doesn't cut latency, neither cuts time dynamic response needs generated. since application sends content right away instead of waiting whole response rendered, client able request assets sooner. in particular, if flush head of html document css , javascript files going fetched in parallel, while server works on generating content. consequence pages load faster. this study might give couple of ideas since didn't gave details types of files trying transfer : to chunk or not chunk
