Google has been on a mission lately to outline some of the cooler, newer features coming to Chrome on their Chromium Blog. Today brings one of the biggest yet: Background Apps.
This feature has existed on various builds of Chrome/Chromium for some time now. But Google hasn’t been touting it, and it wasn’t really clear how it would be used and/or useful. Well today, it’s very clear. And again, very cool. Essentially, Chrome-based web apps are going to be able to be always open, but hidden in the background.
Why would anyone want to use a web app without seeing it? A couple reasons. First, this allows the browser to notify you in realtime of certain updates, like chat requests or new messages. Second, this may allow the browser to pre-render any page so when you do open it, it will load instantly.
Obviously, the trade-off is the memory hit you take by running an app in the background, but presumably these could be coded to have a minimal impact in terms of memory usage.
Essentially, this gives web apps a “push” notification functionality like Apple uses for the iPhone and iPad. It’s a bit different since that system uses Apple own servers to ping your phone and doesn’t require an app to be open at all, but the effect is the same. A user wouldn’t realize the app is open, but would still get alerts about it.
Of course, there’s a security risk there. But Google addresses that in this way:
To protect our users’ privacy, we’ve made this functionality available only to apps and extensions; regular websites will not be able to open background windows. Developers will also need to declare the “background” capability on their apps.
That’s important beyond the security issue. It could make installing web apps actually useful. Up until now, most of the apps in the Chrome Web Store are similar to the ones that already exist on the web. But with this system, you’d have to “install” an app to get this system working.
Update: And here’s an example app Google has made to show how this will work. This book, when installed, will periodically update in the background.

Spent some quality time watching the Home Shopping Network this morning to hear just how the Nook Color will be improved? That's what we thought... but we bit the bullet and tuned in ourselves to get the details for you. Simply put, HSN says Barnes and Noble will start rolling out an over-the-air software package in "mid-April" that will update the Nook Color to Android 2.2, bringing Adobe Flash Player, Angry Birds, and push email of some sort. It'll also apparently include "lots of Nook apps," though the channel's pitchmen only had one to show on TV -- a kid-friendly sketchpad, with a variety of drawing utensils and colored paper. HSN hosts also claim that customers who purchase the Nook Color on the show are "guaranteed to be the very first people updated," though we're not sure we'll take them at their word, considering some of the other fabulous exaggerations we just heard on the air.
