One of the elements of Ubuntu Unity that I have been able to handle the least is Scopes. Part of that is due to the fact that Canonical has done a pretty terrible job of properly showing people what Scopes are and what they do. The other part is… no… actually, that's really the whole problem. Here is how Ubuntu defines this feature:
"Scopes are a complete reinvention of the content and services experience. Users have a new way to access content and apps without having to download individual apps – and developers have the opportunity to be discovered via the device's categorized home screens."
Canonical, the company behind the Ubuntu Linux distribution, wants to bring its operating system to more connected devices and intelligent objects with the launch of its “snappy” Ubuntu Core for the Internet of Things today. Over the last few months, the company launched “snappy” versions of Core on a number of cloud computing services, but given that the whole idea behind Core is to offer stripped-down versions of Ubuntu that developers can then easily customize based on their needs, the Internet of Things and robotics applications are a logical next area of focus for Canonical.
Canonical released a “Snappy” version of its lightweight, Ubuntu Core OS for IoT, featuring an app store, hacker-proof updates, and a 128MB RAM footprint.
Canonical’s delayed Ubuntu Touch phones are apparently still on track for Mobile World Congress release next month, but now the company is on to something based on it that’s potentially much bigger.
Ubuntu Linux has spread to quite a few platforms in its 10-year history, if not always successfully. Today, though, the open source software is tackling what could be its greatest challenge yet: the internet of things. Canonical has released a version of its stripped-down snappy Ubuntu Core for connected devices like home appliances, robots and anything else where a conventional PC operating system wouldn't fly. It's designed to run on modest hardware (a 600MHz processor will do) and provide easy updates, all the while giving gadget makers the freedom to customize the software for whatever they're building. It promises to be extra-reliable, too -- it only applies updates if the code checks out, so you won't lose control of your smart thermostat due to a buggy upgrade.
The Ubuntu developers have corrected a small issue with GTK+, which would allow users to bypass the lock screen in certain conditions. It might be a trivial matter, but it had to be fixed nonetheless.
According to the security notice, "Clemens Fries discovered that GTK+ allowed bypassing certain screen locks by using the menu key. An attacker with physical access could possibly use this flaw to gain access to a locked session."
