That is where the issue of the rolling release comes in. Because of the way Ubuntu does their releases, a lot of packages wind up being out of date. It's nothing major, and you can -- with the help of PPAs -- get those crucial packages updated to the latest releases. A rolling release would put an end to this, because everything would be up to date all the time.
This is probably not going to happen. Ubuntu is deeply entrenched in their release cycle, and I can't imagine they're willing to change. Believe it or not, I'm okay with that. The Ubuntu release cycle has always worked for me. And with their current focus on Unity 8 and Mir, there's really no way they could switch to a rolling release now, even if they wanted it. You see, Unity 8 and Mir are going to do to Ubuntu what Unity did when it replaced GNOME as the default (or what Windows 8 did to the Windows ecosystem) -- it's going to change... a lot.
As we've reported, OpenStack Foundation surveys on how organizations are implementing OpenStack show that Ubuntu is by far the most prevalently used operating system underlying the popular cloud computing platform. That makes Canonical a significant player on the OpenStack scene, but OpenStack isn't the only cloud platform that Canonical facilitates use of.
As one of the important apps to Ubuntu Touch is, of course, an e-mail client. Up to now the Ubuntu Touch email client has been based off the lightweight, Qt-based Trojita application but now it's being forked off entirely for Ubuntu.
Trojita is a Qt IMAP email client talked about for its speed and design. The Ubuntu Touch email app has been based off this code, but now the Ubuntu developers involved are distancing themselves from upstream.
Ubuntu Touch developers have stopped upstreaming their changes to Trojita but instead are now maintaining their own long-term fork of Trojita that's called Dekko. Dekko is the new Ubuntu Touch email client and the old Ubuntu Touch related code has been stripped out of Trojita.
While much of Canonical's recent focus has been about reading Unity 8 for mobile devices, their plan is still to ship Unity 8 by default on the Ubuntu Linux desktop ahead of its next LTS release.
Their plan for a while has been to use Mir by Ubuntu 16.04 LTS on the desktop spin along with using Unity 8 to replace Unity 7 + Compiz + X.Org Server. Will Cooke, the team manager of the new Desktop Team at Canonical, did a guest post on Michael Hall's blog to reiterate these plans.
Unity is the default desktop environment in Ubuntu and it's been around for four years now, although not for the desktop version of the distribution. It was first used in Ubuntu Netbook Remix, which was a flavor dedicated for Netbook use. In fact, Ubuntu Netbook Remix 10.10 Maverick Meerkat was the first to adopt the new Unity desktop.
The regular Ubuntu 10.10 release still used GNOME 2.x for the desktop, which is one of the reasons why some users still say that 10.10 still is the best version ever made by Canonical.
The Ubuntu 14.10 development cycle has been rather uneventful and no major features have been implemented. The same cannot be said about the thousands of other packages that are used in the operating system, as most of them have been updated. This is also true for the Linux kernel.
Despite the fact that Ubuntu arrives like clockwork, every six months, its developers always try to add the latest kernel available whenever possible. Now that the development cycle is coming to an end, Canonical has finally settled on the kernel that will officially ship with the distribution.
The US Air Force has the drones, but now the US Navy has autonomous boats that can steer themselves, patrol a zone, and take a hostile posture, whatever that means. It was just a matter of time until someone thought of having some kind of drones that could guard a fleet on the water. The US Navy was happy to oblige.
