Ubuntu 14.04 LTS: Major Application Updates

Over the last few weeks, we have been talking about the first new LTS version from Ubuntu in two years and some of the major changes to the operating system that you can expect to see once you take the plunge. Today, we are going to list some of the major applications available from the Ubuntu Software Center and the upgrades they have undergone since the last update to Ubuntu’s LTS OS.

Major Utilities and Tool Updates
In addition to the myriad major desktop application updates (which we will cover in the next section), there are a HUGE number of other utilities and tools that have received pretty major updates since the last LTS version a bit over two years ago. Let’s talk about a few:

  • Xen 4.4
  • This is a pretty major upgrade to Xen which is included with Ubuntu at this point. The most noticeable change to anyone who uses it will likely be that it no longer supports 32bit only CPUs (although 32bit client operating system support is still in place). This shouldn’t be a big deal since any modern processor in the last six or so years is 64bit, but it may mean that some people using Ubuntu on older servers or old laptops may need to be aware that Xen will no longer support their CPU family.

We've been busy at the Linux Academy!

At the Linux Academy, helping our student master their skills and expand their knowledge is our number one goal. We’ve recently kicked things into high gear! Today I’d like to tell you some great new features we have been working on, and some special treats we have for you in the coming months.

New Features

We’ve had some excellent suggestions from our users, and we’ve been listening! You’ve been asking for an alternative method to subscribe besides PayPal. I’m happy to announced that we have just finished a major rewrite to our subscription system, and we are now able to accept Visa, MasterCard, and Discover as payment options.

You’ve also been asking us to give you the ability to hide the answers to labs. We’ll that is very studious of you! We are currently in the process of rewriting all the labs to include this feature.


Ubuntu 14.04 LTS User Interface: Menus and Window Decorations

In our last article, we casually mentioned a number of the changes that have taken place between Ubuntu 12.04 LTS and Ubuntu 14.04 LTS over the last two years. Several of those changes are either relatively radical departures from the the established User Interface that Ubuntu has been working so hard to establish with Unity or a complete change of heart since the first version of Unity way back in Ubuntu 11.10. With that release of Unity, it’s fair to say that Ubuntu was trying to shift the UI paradigm on the desktop, pushing it towards where they believed the mobile space was headed (how has that worked out for Microsoft?). Although today’s Unity is largely the same, there are some recent changes in the menuing and window decoration space that show Canonical was not entirely ignoring the user community. Let’s take a look at each.


How To Study For AWS Certifications


One of the most frequently asked questions by our students is “How do I study for the an AWS exam?” and “Which exam should I take?” Here I hope to help create some clarity around the AWS exams and the best way to prepare for exams. In our next post I’ll talk about which exam you should take. After all do SysAdmins need to take the developer cert? (The answer to that is yes, but this is a teaser for our next post). At the Linux Academy we have crafted a pretty unique prep course for each one of these exams. We know that everyone learns differently and personally I’m a strong believer that to truly “learn” a concept not just “memorize questions to pass an exam” you need more than one learning method and you need to practice, hands on in a real environment.


Linux Academy Is Now An Approved Quality Content Provider For CompTIA Linux+

Linux Academy is proud to announce that we are now an approved CompTIA Quality Content Provider.

Now that our Linux+ exam preparation has been Quality Content Approved, this means training centers, instructors and others who are teaching Linux+ are  now able to use the Linux Academy Linux+ exam material for official training!

For more details on the CompTIA Quality Content Partner program check out their page here. You can also take a look at a few of Linux Academy official training partners such as the Linux Professional Institute here.

We’ve been so hard at work adding new content and features that we are sure you’ll find something you’ll like. We now have many Linux courses as well as self-paced hands on labs. Our content also includes a very deep collection of AWS certification courses and AWS self-paced labs!

Ubuntu 12.04 LTS vs. 14.04 LTS: Quick Change Review

With the recent release of Ubuntu 14.04 LTS (affectionately known as “Trusty Tahr”), there are a number of people (and organizations) that have been waiting to upgrade from LTS to LTS desktop or server. The question to ask yourself might be whether to upgrade or to re-install? The answer to that question may lie in some of the changes that have taken place between these LTS versions (a little more than two years between them), so let’s take a quick look at some of them.

The Burning Question
Let’s address the big question now, even before we talk about some of the changes between the LTS versions of this OS. Should you upgrade your Ubuntu 12.04 LTS or perform a clean installation of 14.04 LTS. I would like to say “it depends” and site that your specific configuration, customization and third party repositories may help you make your decision.

Unfortunately, my experience with Ubuntu 14.04 LTS (going from Ubuntu 12.04 LTS) is that you really need to do a full and fresh install. There are a large number of underlying architectural changes to structure, libraries and major components to really insure that your upgrade will complete without major issues. Honestly, if you want a stable system with the latest drivers and utilities that this version has to offer, you need to re-install.
