i'm having issue dropdown boxes using ng-model , changing index of dropdown while being still able use dropdown. for instance, can change index of drop down using code ( http://jsfiddle.net/q5hd6/357/ ). however, when change index defaults empty selection refuses let me select else. html: <select ng-model="recievedselect" ng-options="item.id item.name item in recievedoptions"></select> <button ng-click="changeindex()">change index</button> js: $scope.recievedoptions = [ {id : 0, name: "no"}, {id : 1, name: "yes"} ]; $scope.changeindex = function() { $scope.recievedselect = $scope.recievedoptions[0]; } but if remove track item.id i'm able change indexes manually, can no longer change them button ( http://jsfiddle.net/q5hd6/358/ ). basically, both, sort of lost on go next.

i trying write cusom keras loss function in process tensors in sub-vector chunks. example, if output tensor represented concatenation of quaternion coefficients (i.e. w,x,y,z,w,x,y,z...) might wish normalize each quaternion before calculating mean squared error in loss function like: def norm_quat_mse(y_true, y_pred): diff = y_pred - y_true dist = 0 in range(0,16,4): dist += k.sum( k.square(diff[i:i+4] / k.sqrt(k.sum(k.square(diff[i:i+4]))))) return dist/4 while keras accept function without error , use in training, outputs different loss value when applied independent function , when using model.predict(), suspect not working properly. none of built-in keras loss functions use per-chunk processing approach, possible within keras' auto-differentiation framework? try: def norm_quat_mse(y_true, y_pred): diff = y_pred - y_true dist = 0 in range(0,16,4): dist += k.sum( k.square(diff[:,i:i+4] / k.sqrt(k.sum(k.square(diff[:,

there's way execute every log in hierachy particular son? for example: -parent -son -son2 executing son.log("message") execute son log , parent log. executing son2.log("message") execute son2, son , parent log. that's code: public class helloworld { public static void main(string[] args) { logger parent = loggerfactory.getlogger("parent"); ((ch.qos.logback.classic.logger) parent).setlevel(level.debug); logger son= loggerfactory.getlogger("parent.son"); son.debug("hello"); } } output: 14:15:25.180 [main] debug logger.son- hello world. desired output: 14:15:25.180 [main] debug parent.son- hello world. 14:15:25.180 [main] debug parent- hello world. thanks. that not how works. slf4j logger hierarchy cannot used (and should not be) in way want. basically, each logger, if don't define setting, settings copied parent. in hierarchy, logging level

let's have table named 'neighbors' contains variable 'name', , selecting name , using case statement assign values second variable, 'age'. syntax 1 can use case statement in sql takes 2 different forms: 1) simple case expression: case name when 'george' 36 when 'alfred' 40 else null end age 2) searched case expression: case when name = 'george' 36 when name = 'alfred' 40 else null end age the 2 statements doing same thing. question is, how these statements handled in memory? handled same, or may 1 more efficient other? https://docs.microsoft.com/en-us/sql/t-sql/language-elements/case-transact-sql correct syntax either case name when 'george' 36 when 'alfred' 40 else null end age or case when name = 'george' 36 when name = 'alfred' 40 else null

consider this: we have external server files can downloaded our website (plone based) interface downloading them , try hide direct links as possible jquery.filedownload plugin needs cookie set on file on download i'm trying set our apache configuration replace links this: original: data-files-example.com/folder/subfolder/file.zip replaced: our-website-example.com/_downloads/folder/subfolder/file.zip so, missing part in case is: how set apache work this? i'm trying: namevirtualhost *:80 <virtualhost :80> serveradmin email@our-website-example.com servername our-website-example.com rewriteengine on rewriterule "^/_downloads(.)$" "https://data-files-example.com/$1" [p] rewritecond %{request_method} ^(put|delete|propfind|options|trace|propfind|proppatch|mkcol|copy|move|lock|unlock)$ rewriterule .* - [f,l] rewriterule ^/(.*) http://127.0.0.1:/virtualhostbase/http/data-files-example.com:80/my_plone_websit

this works fine: <li v-for="post in posts"> <a v-bind:href="post.url">{{post.title}}</a> </li> but if change (using v-html instead of template): <li v-for="post in posts"> <a v-bind:href="post.url" v-html="post.title"/> </li> i error: property or method "post" not defined on instance referenced during render. what's weird changing v-html syntax appears invalidate idea of there being post altogether because error being thrown on v-bind:href now. doesn't matter put in v-html attribute -- throw error anyway because mere existence of v-html appears eliminate post object, v-bind:href fails. self closing tags not valid . use. <li v-for="post in posts"> <a v-bind:href="post.url" v-html="post.title"></a> </li>

i have created aws firehose endpoint (might change simple kinesis) receives logs producers , saves them s3 bucket , lambda function consumes data, processes , saves output db. everything works fine. planning creating staging , development flow entire structure. when release new version not capable of replacing entire producers instantly, therefore need keep older production versions until no producer left - because might make breaking protocol changes on new versions. i not sure best approach create versionable system using kinesis , lambda. should copy entire structure new versions (including dev , staging) , make producers write specific versioned stream? or should create mid lambda function inspects packets (which contain version info) , outputs events specific s3 has versioned folders? lambda functions consume data know about. let me use versioning support lambda functions. here structure image first idea here second structure i wonder better solution or there b

i have issue linux ec2 instance can't outbound(ping, curl, yum update, wget, traceroute, etc..) unless have rule in vpc acl inbound rule set allows traffic. my security group , vpc both have outbound rules allows traffic everything. the security group inbound list attached instance looks this: and vpc inbound list looks this(rule 200 1 i'm talking about): if delete inbound rule allows traffic(rule 200), can't outbound. could there i'm missing ? thanks! acl rules stateless, means don't keep track of outbound connections when evaluating inbound connections. if make outbound connection server, acl rule block server's response unless have explicitly allowed inbound connections server in acl. this 1 of primary reasons people use security groups (which stateful) instead of acl rules. looking @ network acl rules, there nothing happening there isn't covered security group rules, why use acls?
