i created actionscript3 framework myself. because hate code out of head. separated in different libs, can combined. whole code documented , docs including examples. the main usage mvc project framework , @ point, when can release it. still want work on extend , improve it. , point need little help. i'm pretty sure find issues in it. in understanding of it, way use or, in worst case, bug in code. so if to, here link: http://codeboxes.com/ and way: published under mit licence, can ever fun want it. ;) not open source! thank commenting , viewing question help. said has valid point. close , think opensource thingy.

when use portable.ninject in xamarin.forms app, instantiating standardkernel results in notimplementedexception . i can consistently replicate problem follows: create xamarin.forms application (in vs2017: cross platform app (xamarin)) configure use pcl i'm interested in android , sake of brevity, removed other platform projects. add nuget package portable.ninject pcl , android platforms then, in app.xaml.cs try following: public app() { initializecomponent(); //ommitting ninjectmodules brevity var kernel = new ninject.standardkernel(); //exception thrown here mainpage = new navigationpage(new mainview()); } what missing here? currently i'm using portable.ninject version 3.3.1. tried xlabs.ioc.ninject package (which uses portable.ninject) , got same result. for experience same problem: tldr; clean projects, , rebuild. explanation: @ first had added ninject pcl, , had forgotten add android project. although added ninject librar...

i'm following along tero parviainen's book "build own angularjs" , i'm finding trouble understanding 1 of concepts introduces when talking $evalasync. in 1 of examples declares watcher calls $evalasync: it('eventually halts $evalasyncs added watches', function() {   scope.avalue = [1, 2, 3];   scope.$watch(     function(scope) {       scope.$evalasync(function(scope) { });       return scope.avalue;     },     function(newvalue, oldvalue, scope) { }   );   expect(function() { scope.$digest(); }).tothrow(); }); seeing example, expect digest cycle iterate twice through watchers until stopping. in implementation of scope, code runs until digest not dirty or there no more $evalasyncs in queue. scope.prototype.$digest = function () { var ttl = 10; var dirty; this.$$lastdirtywatch = null; { while (this.$$asyncqueue.length) { var asynctask = this.$$asyncqueue.shift(); asynctask.scope.$eval(asynctask.expression); } dirty...

i have created webapp in docker. webapp uses other docker images such redis, mariadb. these , running locally. have created image of webapp. have 3 images : webapp(which not up), redis , mariadb up. when tried run image of webapp fails start .. unable connect other images (redis , mariadb). how can make webapp image communicate other required images you need create docker network attach containers together. docker network create net then can either start containers network option: docker run --network net ... or if containers running, can connect them network docker network connect net <container-name> once that, containers can communicate each other using container name hostname, example: redis, mongo ...

i have few questions regarding scharr derivatives , opencv implementation. i interested in second order image derivatives (3x3) kernels. started sobel second derivative, failed find thin lines in images. after reading sobel , charr comparison in bottom of this page , decided try scharr instead changing line: sobel(gray, grad, ddepth, 2, 2, 3, scale, delta, border_default); to line: scharr(img, gray, ddepth, 2, 2, scale, delta, border_default ); my problem seems cv::scharr allows performing first order of 1 partial derivative @ time, following error: error: (-215) dx >= 0 && dy >= 0 && dx+dy == 1 in function getscharrkernels (see assertion line here ) following restriction, have few questions regarding scharr derivatives: is considered bad-practice use high order scharr derivatives? why did opencv choose assert dx+dy == 1 ? if call scharr twice each axis, correct way combine results? using: addweighted( abs_grad_x, 0.5, abs_grad_y, 0.5, ...

i feel bootstrap heavy use in production using more bandwidth. there way short issue ? hope lot ways there. new development had keen interest know .. you can use following methodologies improve site performance while using bootstrap. method 1 : use minified versions of the .css and .js method 2 : use  gzip  compression compress sent client browsers method 3 : use cdn , content delivery networks helping serve commonly used css js contents. can use 1 of bootstrap cdn instructed bootstrap ( https://getbootstrap.com/docs/3.3/getting-started/ ) <!-- latest compiled , minified css --> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-bvyiisifek1dgmjrakycuhahrg32omucww7on3rydg4va+pmstsz/k68vbdejh4u" crossorigin="anonymous"> <!-- optional theme --> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7...
