Does the Zookeeper Watches system have a bug, or is this a limitation of the CAP theorem?
clojure,zookeeper,watch,stm,cap-theorem
This seems to be a limitation in the way ZooKeeper implements watches, not a limitation of the CAP theorem. There is an open feature request to add continuous watch to ZooKeeper: https://issues.apache.org/jira/browse/ZOOKEEPER-1416. etcd has a watch function that uses long polling. The limitation here which you need to account for...
Android Wear Picture ticker

You should use Canvas.save, Canvas.rotate and Canvas.restore. Imagine, that you always draw things in the same place, but the underlying canvas is being rotated, so you will draw in the right place. Consider the example from the Santa Tracker: for (int i = 0; i < mCloudBitmaps.length; i++) { canvas.save();...
Angularjs directive creates watches
You could manually get the interpolated values once with $parse or scope.$eval, and use one-time binding ({{::var}}) inside the template: .directive('inputNumber', function ($parse) { scope: {}, template: '<input type="number" min="{{::min}}" max="{{::max}}" ng-model="value"/>', link: function($scope, $element, $attrs){ $scope.min = $parse($attrs.min)($scope.$parent); $scope.max = $parse($attrs.max)($scope.$parent); // etc... } } The usage would be:...

gulp.watch() not running associated task
Support for passing in watch tasks to the gulp.watch API as an array requires gulp version 3.5 at minimum. The gulp.watch API accepts an array of tasks only in gulp version 3.5 and up. My local gulp was version 3.4. I updated gulp to latest 3.8 version and my watch...
angular $digest infinite loop on call of $watchCollection
Your watch function is the problem. Whenever you change $scope.x.height, it will detect that x has changed and trigger the watch once more. Either move that height property out of x and put it somewhere else, or ensure that the value won't be different no matter how many times you...

AngularJs $watch issue
angularjs,controller,directive,watch
That's because $watch is just watching the reference of scope.data.nodes, so no matter what you push or pop, the reference will not change. Instead of using $watch, you can use $watchCollection. It will detect the length of the array. scope.$watchCollection('data.nodes', function(){ return scope.render(scope.data, scope.query); }); ...
Why am I getting $digest () iterations reached? How can I track my recursive script's activity?
javascript,angularjs,counter,watch
In the $digest cycle your {{incrementCounter()}} causes {{counter}} to change which causes a new $digest cycle which causes another evaluation of {{incrementCounter()}} ad infinitum. Basically if you have a counter which is incremented every $digest cycle, you can't have that variable affect the result of any $watched expression. You'll need...
NodeJs: external javascript with dependencies

Angular JS $watch vs $on
javascript,angularjs,events,listener,watch
The $watch function is used to watch variables on the scope. Scope inheritance allows you to watch parent scope variables as well, so that is definitely the way to go for your use case. As you correctly said, $on is used to watch for events, which you can $broadcast to...
Directive Angularjs, $watch and HTML Element

You have a template in your directive, so everything inside it will be replaced by that <div> tag. It works fine if you remove the template.

Gulp not watching .scss files?
I think this come from the fact you have two tasks default. I guess gulp ignore the first one (with gulp.watch) to only trigger the second one. Then you have dependencies with watch but seems like watch does not exist ? You can install gulp-watch locally, and include it in...

Deep watch doesn't work
The problem is in this line: <span contenteditable ng-model="phone">{{ phone }}</span> Since the phones is an array of primitive values, ngRepeat will create a copy of each phone on a scope created by ngRepeat. Then your ngModel is bound to this copy so the original object isn't changed and this...

how to show, hide or change an element attribute when a controller async function resolves?
angularjs,asynchronous,watch,ng-show,ng-hide
Your code looks pretty incomprehensible to me. For example returning true from event observer doesn't do anything at all, AFAIK. Also, don't manually set class="ng-hide" when using ng-show on the same element. Anyway, if I understand it correctly, you just need to create a boolean property and set it after...
How to use watch with a function in zsh?
The watch utility executes commands with sh -c. So, if you want to execute a zsh function, you need to execute zsh explicitly. For instance, if your functions are defined in a /path/to/functions file, you can do: watch 'echo hello | zsh -c "source /path/to/functions; my_fun"' or watch 'zsh -c...
How to track behavior of ngModel array item using .directive

You could add a parent directive which will collect the dirty elements, and will add new element once it detects all of the other elements are dirty: Check this plunker. HTML: <div collect-input> <div class="form-group" ng-repeat="(i, name) in name_list track by $index"> <div class="row"> <div class="col-xs-12"> <input class="form-control" type="text" ng-model="data.name_list[i]"...
Why is $watch not firing even with objectEquality set to true?
$scope.$watch takes a callback function (not the name of one). So, changing to this should work: var recalculateInfoBox = function () { console.log('in recalc'); $scope.infoBox.width = '100px'; }; $scope.$watch('scores', recalculateInfoBox, true); From the docs: $watch(watchExpression, listener, [objectEquality]); Registers a listener callback to be executed whenever the watchExpression changes. ...
Grunt trouble running multiple tasks
I think I'm satisfied with the "newer" plugin. I was never able to get the watch to run multiple tasks from a registered task and maybe that makes sense though it would be a nice feature to pick and choose which tasks to watch. I'm simply running "watch" and it's...
AngularJS - Trigger $watch in directive when a different element changes
javascript,angularjs,angularjs-directive,watch
You need to add function to $formatters pipiline (because your are changing model from controller, not from view - then $parsers work) and run it if model is dirty: myApp.directive('customValidator', function() { return { restrict: 'A', require: 'ngModel', link: function(scope, elem, attrs, ngModelCtrl) { ngModelCtrl.$parsers.unshift(function(value) { if (value) { ngModelCtrl.$setValidity(ngModelCtrl.$name,...
Preventing from duplicated code in get requests in AngularJS

Angular: Best practices for angular $watch registration
As it turns out - after investigating further - I didn't fully understand how $watch worked. http://angular-tips.com/blog/2013/08/watch-how-the-apply-runs-a-digest/ really helped shed some light on the situation. As it turns out - simply changing a variable that is being watched won't trigger a digest loop by itself. The reason $timeout worked was...

How to know which data has been changed in an array?
javascript,ajax,angularjs,watch
You have the angular two-way data binding so it should automatically update your ng-repeat when the model changes.

How can I add to this command to make “notifications” via a new terminal pops up with a message?

adding watch for an editable row in angularjs
I'd refrain from using $scope.$watch() and turn to a more efficient solution. You can use the e-ng-change directive to fire a function computing new value of $scope.editForm.split every time the billAmt value changes. It would look like this: <tr ng-repeat="expense in viewModel.expenses"> <td>{{expense.eid}}</td> <td><span editable-text="expense.billAmt" e-ng-model="editForm.billAmt" e-name="billAmt" e-form="rowform" e-ng-change="checkSplit();">{{expense.billAmt}}</span></td> <td><span...

JS reference inside function and watch
Since oneObject refers to an object, changing it will also change other references to that object. You can solve this with a closure.

How do I watch every object in a collection?
