PhoneGap is a wrapper type application that allows you to package HTML5/CSS3 Web Apps inside of a native app. This is a great feature because it gives you the ability to distribute your app via the app stores and have a so called “native app” without having to learn Java and Objective-C to code in the operating system native languages.

4 JavaScript Frameworks You Need To Start Using Today
The web has quickly moved from fancy websites running strictly on HTML and a server side programming language, to dynamic web applications whose front ends run on JavaScript. JavaScript is an old language (created in 10 days). It has its problems but it has major advantages including its flexibility and user interface. Browser JavaScript engines are showing massive improvement, and so is JavaScript. Here are 4 awesome JavaScript frameworks you need to be aware of if you want to be a great web developer these days.

Tip: Apple Airplay And HTML5 Video Tag
HTML5 has been evolving super fast. Not only that, Apple, the driving force (and owner) of webkit, has been making changes as well. In IOS 4.0 a tag called x-webkit-airplay was needed in order to give controls to the video to airplay stream to an Apple TV.
The exact command needed was x-webkit-airplay=”allow”. By default the x-webkit-airplay was actually set to “disallow.” If you wanted your video to have the ability to use AirPlay and stream to an Apple TV you needed to turn it on or “allow” it with the x-webkit-airplay parameter. However, this changed in IOS 5.0. Apple changed the default behavior of x-webkit-airplay to be x-webkit-airplay=”allow.”
So by default if you’re using the video HTML5 tag it will be able to use AirPlay and stream to an Apple TV. You only need to worry about the parameter x-webkit-ariplay if you want to set x-webkit-airplay=”disallow” and not allow streaming over AirPlay to an Apple TV.
Open Source News Roundup — Weekend Edition
Linux
Adobe fixed a vulnerability in its Flash software; this newly discovered exploit affected not only Windows but Mac and Linux as well. Make sure you’re checking for updates.
The 2012 Ubuntu Developer Summit (UDS 2012) wrapped up on Friday, May 11th. Reports from the summit are slowly filtering on to the internet; apparently the Ubuntu folks are focused on doing rather than talking, since less than 100 unique reports have appeared in news streams.
While presenting at UDS 2012, Electronic Arts (EA) announced release of two web-based games for Ubuntu–Command & Conquer Tiberium Alliances and Lord of Ultima–at the developers’ summit. It’d be nice if EA told the rest of the world; so far the company hasn’t issued a press release.
Speaking at UDS 2012, Chris Kenyon, VP of Canonical Ltd., said 5% of all new PCs will ship pre-loaded with Ubuntu. No wonder Dell feels some pressure to create a Linux-based developer laptop.
Uh-oh. Keep an eye on this: Ubuntu may have forked the Gnome Control Center, according to a developer at UDS 2012. Others say it’s more of a patch than a fork. Will there be any conflicts in the future about Ubuntu’s direction on Control Center? (Continue)

Linux
Dude, you’re getting a Dell! Well, maybe–if you’re an open source software developer. Looks like Dell took to heart feedback from the open source community, an began an experiment in which Ubuntu’s 12.04 operating system will be featured on a Dell’s XPS13 Ultrabook. Dell’s commitment to Ubuntu-loaded machines has been problematic—“spotty” is too generous a word since Dell doesn’t currently offer a pre-loaded system at its own Ubuntu page. (http://dell.com/ubuntu actually redirects to a generic Dell product page). A real commitment to Ubuntu as an operating system will take more than pre-loaded software, as Ars Technica notes; this exploratory project could be finally represent the beginning of something big in open source for commitment-phobic Dell.

Getting Started With Google Analytics For Your Site
Everyone has heard about Google Analytics at some point. But what does it exactly do? It’s a web analytics tool that shows you how people find your site (for instance through a search engine, ads, etc), how they navigate through your website and how they become costumers. You’re also able to track your mobile websites, mobile apps and web enabled mobile devices, bot high end and non-JavaScript enabled phones. You can find out which browser and which operating system your visitors use, which search queries they use and what the landing pages are. You can also see how many new and returning visitors you have. And what’s also important to know is how long they stay on your website.

When should you disable root login? Disabling root login is a super easy trick to increase security on your machine. Let’s take a look at why and when you should disable the root login and also when it’s OK to keep root login enabled. Root or administrator users are the default users on almost all systems.

Let’s first look at when it is best practice to disable root login.
