Popping Out of Hidden Overflow The following is a guest post by Agop Shirinian. Agop ran into an interesting scenario where he needed an element to be scrollable in one direction, while allowing the overflow in the other direction. You'd think that's what overflow-x and overflow-y are for, but it's not that simple. I'll let Agop explain. So you're tasked with creating a scrollable menu with submenus that pop out when you hover over a parent menu item. Simple! Create a list for the menu, add some nested lists for the submenus, position the nested lists based on their parent list items, voilà! Wait, that's not right. What gives? The Problem If we look at the W3C spec, we find the following explanation: The computed values of ‘overflow-x’ and ‘overflow-y’ are the same as their specified values, except that some combinations with ‘visible’ are not possible: if one is specified as ‘visible’ and the other is ‘scroll’ or ‘auto’, then ‘visible’ is set to ‘auto’. Basically, this: overflow-x: visible;overflow-y: auto; Turns into this:
Semantic Versioning 2.0.0 Cookie-based Authentication in AngularJS Single Page Apps are ruling the world and AngularJS is leading the charge. But many of the lessons we learned in the Web 2.0 era no longer apply, and few are as drastically different as authentication. Depending on where you build and release your AngularJS app, there are different ways to handle authentication and I hope this post clears some of that up. CORS is an oft-misunderstood feature of new browsers that is configured by a remote server. Like many browser features, CORS works because we all agree that it works. That means certain browsers do not enforce it, so it is not relevant there. Configuring CORS on the Server The way CORS works is the server decides which domains it will accept as clients. I won't get into the details of configuring CORS on the server side, but it's really just setting some headers. There is one header in particular you must have if you want to do session based authentication in a single page app: Access-Control-Allow-Credentials: true which we show next.
A JavaScript library for building user interfaces | React A Simple Component React components implement a render() method that takes input data and returns what to display. This example uses an XML-like syntax called JSX. Input data that is passed into the component can be accessed by render() via this.props. JSX is optional and not required to use React. Live JSX Editor Compiled JS A Stateful Component In addition to taking input data (accessed via this.props), a component can maintain internal state data (accessed via this.state). An Application Using props and state, we can put together a small Todo application. A Component Using External Plugins React is flexible and provides hooks that allow you to interface with other libraries and frameworks. Input Type some *markdown* here! Output
Easier Nested Layouts in Rails 3/4 • 55 Minutes Blog A layouts recap Any non-trivial web application will have multiple HTML layouts. For example, a login page may use a simple layout with no header and footer, whereas authenticated pages will have navigation bars and breadcrumbs. Rails offers a basic solution for this in the form of layout templates. <html><head> ... You can have as many layouts as you’d like, and Rails makes use of convention over configuration to automatically pair up layouts with corresponding controllers of the same name. Nested layouts, the (awkward) Rails way So far so good. Every page in the app needs the standard HTML boilerplate with our common stylesheets, JavaScripts. Some frameworks call this template inheritance. The official Rails guide provides an explanation with some examples. A nicer, helper-based approach If you do some searching (as you may have done to find this article!) An example Here’s how to use parent_layout to implement the “base” and “application” layouts from our earlier example. <! That’s it!
java - How to increase IDE memory limit in IntelliJ IDEA on Mac? How To Link The Wireless Subwoofer To Your Soundbar (HW-D Models) : | Samsung Page 1. Linking The Subwoofer To Your Soundbar Getting Started: The subwoofer's linking ID is set at the factory so the Sound bar and subwoofer should link automatically when the Sound bar is powered on. However, if the link indicator does not light when the Sound bar and subwoofer are both powered on or if your Sound bar has been serviced recently, follow the steps below to set the ID and link. You Will Need: A small, pointed object such as a paper clip Sound bar remote control Clear any obstacles between the Sound bar and the subwoofer Plug in the power cord of both the Sound bar and the subwoofer Power off the Sound bar if on, and leave off With the Sound bar OFF and the subwoofer connected to a power source locate the ID Set button on the back of the subwoofer, left of the serial number sticker. Using a small pointed object (paper clip) press the ID Set button for 5 seconds until the Standby indicator is turned off and the blue Link LED begins to blink rapidly. Notes:
Top 10 Freelance AngularJS Developers for Hire in July 2015 AngularJS is the framework of choice for multiple high-end web applications.

Q: How does scope inheritance work in AngularJS? Scope inheritance in AngularJS is prototypal for child scopes, but not for isolated scopes. When building custom directives, it is possible to create an isolated scope. Directives also have the ability to transclude scope onto contained elements. At this point, it seems very important to note that it is possible to traverse scopes, in all directions. Q: What exactly are controllers? Controllers are bound to their scope, and so is their lifecycle. Q: Please explain what “. “.
