Ubuntu, the popular Linux distribution, has been on a steady six-month release schedule for eight years. Every four versions, that is, once every two years, one is marked as Long Term Support (LTS). While typical (non-LTS) releases are supported for around 9 months, LTS versions are provided with five years of updates. Of course, each version, LTS or not, is free. The choice to stay on a specific branch is something else entirely.
For most home users, it will probably make sense to pick up the latest version available on your update manager. Of course, each new release will change things and that can be a problem for some users. That said, given that releases come in six-month intervals, it does make sense to keep up with the changes as they happen, rather than fall behind and have a real shock in five years. Enterprise customers, on the other hand, would love to adopt an operating system which never changes, outside of security updates. Windows XP is a recent example of where enterprise customers will actually pay to not upgrade. These customers will benefit most from LTS.
First and foremost, Canonical, the company behind Ubuntu, wants to catch the wave of PC users who are looking to upgrade from Windows XP and Windows 7. It is free, it has a web browser and an office suite, it is stable and secure, and they suggest that it will be easy to deploy and manage for governments and other institutions.
The interface is Unity7, although users will have the option to try Unity8. The latter version is Canonical's attempt to cover all form factors: phones, tablets, TVs, and desktops.
They probably could have chosen a different number, if only for the jokes.
Ubuntu 14.04 LTS is available now at their website. It is free. If you want it, go get it unless you already have it.
Hackers Compromise Ubuntu Forums Database, Deface Website, And Make Off With The Encrypted Passwords and Email Addresses of Nearly 2 Million Users

A group of hackers attacked and defaced the Canonical-backed Ubuntu Forums website yesterday. The hackers used an exploit to gain unauthorized access to the forum database and made off with data from approximately 1.82 million users. To make matters worse, the attackers then defaced the forum site itself by placing a landing page poking fun at the site administrators and boastfully including two twitter handles: @Sputn1k_ and a mention of @rootinabox.
Canonical has not released details on how the attackers accomplished the data breach, but stated that its security team is working to get the site back up and looking into what exactly happened.
From what has been discovered thus far, the hackers have reportedly made off with the passwords, usernames, and email addresses of all its users.
The company recommends that users change passwords on any other services immediately if they used their Ubuntu Forums password for log-ins on other websites or online services.
ZDNet managed to snag a screenshot of the defaced web page.
Fortunately, all of the passwords in the database were salted and hashed, and not stored in plain text. The exact hashing method was not detailed, however. Also, other Ubuntu services were not affected and user data in services such as Ubuntu One (Canonical’s cloud storage offering) is still safe.
If you had an account on the Ubuntu Forums and used the same password, you should change your passwords now just to be on the safe side. Users of the forum should keep an eye on this announcement page for more details on the hack and updates on the forum restoration process as it progresses.

Canonical released its the Ubuntu 13.04 “Raring Ringtail” Linux distribution earlier this week. The updated operating system incorporates a new Linux kernel, newer pre-installed applications, and a tweaked Unity desktop environment. Enterprise and server users also have updated server software stacks to look forward to, including the latest juju and OpenStack (Grizzly) releases.
Ubuntu 13.04 continues in the direction of convergence set in motion by Canonical and its founder Mark Shuttleworth. It is the first step towards Ubuntu running on many types of devices (including mobile) as it includes an updated Unity interface. The 13.04 release still uses the X window system, but Canonical has made tweaks to Unity and is offering up an optional download of the new Mir display backend that users can install. Mir is the display server that Ubuntu will be switching to with its next LTS release and that will reportedly enable a cross-platform Ubuntu/Unity experience. The Unity tweaks include disabling Workspaces and the “show desktop” button on the desktop (though they can be re-enabled in settings). There have also been tweaks to Ubuntu’s Dash UI, including a typo-tolerant search function and new result sorting options. It will not be until the next release that users will really start to see Ubuntu’s plans of convergence come together (heh), but even with the small changes present in 13.04, the traditional desktop OS is making considerations for mobile devices.
While the visual changes are minimal on Ubuntu 13.04 compared to 12.10, the new release does update a lot of the underlying software.At least on the outside, Ubuntu 13.04 has not changed much from its 12.10 predecessor. Ubuntu 13.04 is based on the upstream 3.8.8 Linux kernel, and incorporates a number of updates to the pre-installed applications and core software. The updates include Unity 7, LibreOffice 4, and Python 3.3 (future versions of Ubuntu will remove Python 2 completely, though it will still be available as a downloadable package). Gwibber has also been replaced with a new service called “Friends” that takes all of your social networking accounts and combines them under your Ubuntu Online account.
Additionally, Ubuntu 13.04 also no longer includes the Wubi installer, which allowed users to install Ubuntu as a program within Windows and got around the need to mess with partitioning. Although there was a bit of overhead in doing the install this way, it was noticeably easier for new users than other methods. Canonical suggests that users interested in trying out the new operating system should simply use the live media, but installing it in a VM such as VirtualBox or VMWare may be more appropriate as some of the functionality is missing from the Live DVD environment in my experience (at least if you also want to try out functionality or other Linux software that would require a restart). Canonical has also cut the support time in half for Ubuntu 13.04 (and all future interim releases) from 18 months to 9 months. Hopefully the development team puts the reduced support workload to good use by investing the time in quick and stable releases.
So far, Ubuntu 13.04 has been getting positive reviews, though some users have run into issues running the operating system on their particular hardware (a bit of instability is expected with a new release, however).
If you are interested in Ubuntu 13.04 “Raring Ringtail,” you can read more about the changes in the official release notes and grab a download of the OS from the Ubuntu website or the updater if you are currently running Ubuntu 12.10.

Earlier this month Canonical showed off a new version of its Ubuntu operating system intended for mobile phones. The Ubuntu for smartphones operating system is meant to extend the Ubuntu UI and UX to the smartphone screen. Canonical wants its OS to span from servers to phones and Ubuntu for phones is the latest step in that plan.
While there is no official hardware yet, the new operating system will be aimed at both low-end and high-end smartphones alike. It will support the standard array of smartphone functions–phone, sms, email, web browsing, and apps–along with the familiar Ubuntu user interface that is navigated by touch gestures. Ubuntu for phones will run on x86 and ARM hardware and is compatible with the Android Board Suppot Package. That means that users can actually run Ubuntu on many existing smartphones which are currently running Google's Android OS. Unlike Android, there is no Java VM, and the Ubuntu for phones operating system can run both HTML5 and native applications. At CES, Canonical demonstrated the OS using a Galaxy Nexus smartphone.
Ubuntu smartphones will feature a familiar Unity-like user interface with a number of tweaks to make it easier to navigate using a touchscreen. The OS will use a feature called Edge Magic, which includes swipe gestures inwards from each side of the phone to open applications, read notifications, change settings, and return to the home screen. Users can also use voice and text commands to control the smartphone. For example, users can swipe left to open the application launcher, drag from the left side to the right side of the screen to display all currently running apps, and drag up from the bottom to open application-specific settings. Swiping from the right acts as the 'back' function while dragging down from teh top opens the notifications and device-wide settings. There are no hardware buttons with Ubuntu for smartphones, and Canonical founder Mark Shuttlework has stated that keeping UI elements hidden until needed was a priority with Ubuntu for phones.
Ubuntu for phones is aimed at a wide range of smartphone hardware. On the low end, Ubuntu needs at least a dual-core ARM Cortex A9, 1GB of RAM, and 4GB of internal storage. The budget smartphones will run native apps (ideally) faster than similar code on Android due to the apps being closer to the hardware. Multitouch will be supported but the destkop functionality when the phone is docked is not available. On the other hand, high end smartphones will be able to access a full Ubuntu desktop when the phone is docked along with a mouse and keyboard.
Additional features of Ubuntu for smartphones include global search of applications, content, and products, Deep Content Immersion, and personalized artwork on the welcome (lock) screen. Further, Ubuntu One cloud storage, enterprise management tool compatibility, and regular updates are also rolled into the operating system. Ubuntu does include scopes which are similar in function and aesthetics to desktop Ubuntu. The scopes include a list of applications, contacts, videos, and music (among others).
The following chart lists the recommended/referrence specifications for budget and premium smartphones running the Ubuntu mobile OS.
|Entry Level||High End|
|SoC||dual core Cortex A9||quad core Cortex A9 or better|
|RAM||1GB preferred||minimum of 1GB|
|Storage||4-8GB eMMC + SD card||min 32GB eMMC + SD card|
|Display Resolution||WVGA 800x400||720p or 1080p|
Interestingly, users of the Galaxy Nexus smartphone will be able to test drive Ubuntu for smartphones later this year by flashing their device with the new OS. As far as retail hardware with Ubuntu pre-installed, Canonical is reportedly working on developing partnerships with handset makers. Canonical hopes to being shipping devices begining in Q4'13 or Q1'14.
From the various video demonstrations of the Ubuntu for smartphones operating system, it appears extremely slick and user friendly. Curiously, Canoncial was not willing to let CES attendees go hands-on with the reference phone, which may mean that the operating system is not quite ready for prime time. Despite that hesitation, I do think that Ubuntu for smartphones shows a lot of promise as a mobile, touchscreen-controlled operating system.
It is certainly a project that I will be following closely. With the untimely hardware failure of my Nokia N900, I am in need of a new power user-friendly smartphone. And an Ubuntu-powered mobile sounds like the perfect upgrade for me!
