ReactiveMongo is an extremely convenient toolkit for working with MongoDB in Scala applications. But, at the same time, its documentation does not cover some of the typical scenarios, so sometimes it takes time to find the right solution. One of such tasks - storing polymorphic objects in a database - is the focus of this blog post.
The SysGears Team is pleased to announce the availability of Apollo Universal Starter Kit with Hot Code Reload for backend & frontend.
This post describes two approaches to implementing file download in Lift framework. Firstly, we will have a look at the implementation that uses ResponseShortcutException described in the Lift Cookbook. Then, I'll show how to solve the same task with the help of REST service in the way that follows a common Lift approach. Each of the methods has its own pros and cons, so it's up to you to decide which one works better for your task.
Modal dialogs are designed to bring important pieces of information to users from any page without changing an active routing state. It is often convenient to utilize a modal dialog that itself contains a number of views and its own routing. And, since the $ionicModal service does not provide this functionality, here is where custom modal implementations come into play.
It is often important to simultaneously show a fairly large number of elements on a web page to provide users with the most concise information possible. In order to make all those elements visible on a screen, their functionality usually has to be considerably limited. That is when the ability to open every separate element in a fullscreen view can be very helpful. This post shows how this can be achieved in AngularJS, with two custom directives which allow to move elements to a fullscreen view without changing their scope.
Recently, I have been looking for a way to implement thread synchronization in a Grails application which is hosted on several nodes on Rackspace. And while it's rather easy to synchronize threads within a single servlet container, it might be difficult to do it when the same data is simultaneously updated from separate server nodes. This post shows how this task can be solved with Hazelcast.
This note shows how to get the width and height of an image inside of an AngularJS controller with the help of ng-flow library. First of all, you can get image dimensions by using the Image element constructor and specifying the following
