consider following 3 snippets specified files: <!-- _includes/my_var.html --> {% assign my_var = 'foo' %} and <!-- _layouts/default.html --> {% include my_var.html %} ... and post: --- layout: default --- i'd reference {{my_var}} the last 1 doesn't appear see variable defined in includes file. nil value of my_var . wrong expect should in scope? if so, what's alternative approach? you cannot layout variables page or post. but, looks configuration variable, can set in _config.yml , access anywhere site.my_var .

in angularjs controller, have variable $scope.name assigned input's ngmodel . i wanted save value of $scope.name normal variable, process in controller without changing value of input box. so did var name = $scope.name the issue is, 2 seem linked... when change value of name , value of $scope.name changes, , changes value of input box. how can stop this? how can assign $scope variable normal variable, once, without continued binding? thank you! you need use angular.copy() like: var name; $scope.name = 'name'; function copy(){ name = angular.copy($scope.name); } see more

i have date in following format: column a: day (number form) column b: month (number form) column c: year (yy number form, in case 15 , 16 2015 , 2016) column d: hour (number form, 0 through 23) column e: minute (number form) how can convert timestamp (namely, timestamp representing number of minutes)? don't see kind of "dateserial" type function in excel (at least on mac version). you can formula: =date(2000+c1,b1,a1)+time(d1,e1,0) this number around 42000, need format in number format want. then if want time difference between 2 rows use: =f2-f1 and format cell custom format of [hh]:mm:ss note method excel stores date/time is: dates whole numbers each day since jan 1st 1900 in 42000's. time decimal based on 24 hours being 1. so both current time 42531.63956 or 6/10/2015 3:21:33 or so, when mask applied. excel uses method can math on values. method on how output displayed depends on format of cell in number resides.

i using highcharts solid gauge make donut charts. i want blue series 3d. want green series 3d. how do this? if not possible, want red series striped, not solid. thank help. please ignore bugs. based on can research, doesn't seem can apply 3d settings solid gauges. you can donut charts, however, can see in example: http://jsfiddle.net/brightmatrix/nxkv5woh/ . all added here following code: chart: { type: 'pie', options3d: { enabled: true, alpha: 45 } }, this result: as striped series, there highcharts plug-in pattern fills might helpful you: http://www.highcharts.com/plugin-registry/single/9/pattern-fill . if, however, wanted banded effect looks spokes on wheel, achieve "dummy" series of even-numbered data on separate series, each data point has alternate color. i hope information helpful.

recently planned revamp our existing web-app built in jmvc . , decided go angular-2. and test load size, did following: ng new test123 cd test123 ng build -prod and deployed dist folder content on apache , showed 1.0mb transferred . my entire jmvc application, business logic hardly 1.2mb when loaded in browser. what can decrease size of angular-2 app after deployment? as per comments, ng2 team working on reducing size of framework nearing release. prior this, following typical http conventions minimising js size main thing, i've found webpacks optimisations heavily reduce size of generated js substantially. thats 313kb entire angular2 code base entire app includes inline html , styling (i'm not sure result hello world example though). the webpack plugins can use webpack.optimize.occurenceorderplugin(true) webpack.optimize.uglifyjsplugin() webpack.optimize.dedupeplugin() hope helps!

i trying check if number (input string ) power of 2. problem number might greater 2^64 (long long limit). if store in double cannot binary operations on (so trick v & (v - 1) == 0 not work). here solution stumbled upon: public class solution { public int power(string a) { string dividend = a; stringbuilder str; if (a == null || a.length() == 0) return 0; if (a.length() == 1 && a.charat(0) == '0') return 0; while (dividend.length() > 0 && !dividend.equalsignorecase("2")) { str = new stringbuilder(); int carry = 0; int n = dividend.length(); if (n > 0) { int num = dividend.charat(n - 1) - '0'; if (num % 2 == 1) return 0; } (int = 0; < n; i++) { char c = (char) (dividend.charat(i) - '0'); i...

i have question has straight forward answer, asking here make sure. if want develop app users (e.g. snapchat, wordfeud etc.), how do it? have use database of kind? users not have information stored them, nothing more username , score collection. can without using databases? , how set app having users? you need database. simplest, can set mysql database on server, , make queries it. you can follow tutorial: http://codewithchris.com/iphone-app-connect-to-mysql-database/

given matrix a*b , find min sum of differences between max element , other elements of possible submatrixes of size xy eg 2 3 4 5 6 1 for submatrix of sizes 2*2 2 3 5 6 max = 6 sum of diffs = |6-2|+|6-3|+|6-5|+|6-6| = 8 3 4 6 1 max =6 sum of diff = |6-3|+|6-4|+|6-6|+|6-1| = 10 ans = 8 minimum surely brute force approach checking each possible submatrix , calculating diff between max , every element

i have multiple canvases, each data-id attribute used retrieve dataurl in order draw image so: <canvas data-id='2' class='drawing-result> the following put them in last canvas: var $canvases = $(".drawing-result"); (var i=0; i<$canvases.length; i++){ var canvas = $canvases.get(i); var context = canvas.getcontext('2d'); var imageobj = new image(); imageobj.onload = function(){ context.drawimage(this, 0, 0); }; // skipping code retrieving dataurl using data-id imageobj.src = dataurl; i suspect may have shallow copying things, can't case because put var everywhere. javascript's var variable declaration function scoped, not block scoped. context being overwritten every time loop runs. instead of for-loop, use jquery's .each() function: $(".drawing-result").each(function (i, canvas) { var context = canvas.getcontext('2d'); var imageobj = new image(); imageobj.onload = fun...
