Canonical last week released the
Ubuntu 18.04 LTS platform for desktop, server, cloud and Internet of Things use. Its debut followed a two-year development phase that led to innovations in cloud solutions for enterprises, as well as smoother integrations with private and public cloud services, and new tools for container and virtual machine operations.

The latest release drives new efficiencies in computing and focuses on the big surge in artificial intelligence and machine learning, said Canonical CEO Mark Shuttleworth in a global conference call.

Ubuntu has been a platform for innovation over the last decade, he noted. The latest release reflects that innovation and comes on the heels of extraordinary enterprise adoption on the public cloud.

The IT industry has undergone some fundamental shifts since the last Ubuntu upgrade, with digital disruption and containerization changing the way organizations think about next-generation infrastructures. Canonical is at the forefront of this transformation, providing the platform for enabling change across the public and private cloud ecosystem, desktop and containers, Shuttleworth said.

“Multicloud operations are the new normal,” he remarked. “Boot time and performance-optimized images of Ubuntu 18.04 LTS on every major public cloud make it the fastest and most-efficient OS for cloud computing, especially for storage and compute-intensive tasks like machine learning,” he added.

Ubuntu 18.04 comes as a unified computing platform. Having an identical platform from workstation to edge and cloud accelerates global deployments and operations. Ubuntu 18.04 LTS features a default GNOME desktop. Other desktop environments are KDE, MATE and Budgie.

Diversified Features

The latest technologies under the Ubuntu 18.04 hood are focused on real-time optimizations and an expanded Snapcraft ecosystem to replace traditional software delivery via package management tools.

For instance, the biggest innovations in Ubuntu 18.04 are related to enhancements to cloud computing, Kubernetes integration, and Ubuntu as an IoT control platform. Features that make the new Ubuntu a platform for artificial intelligence and machine learning also are prominent.

The Canonical distribution of Kubernetes (CDK) runs on public clouds, VMware, OpenStack and bare metal. It delivers the latest upstream version, currently Kubernetes 1.10. It also supports upgrades to future versions of Kubernetes, expansion of the Kubernetes cluster on demand, and integration with optional components for storage, networking and monitoring.

As a platform for AI and ML, CDK supports GPU acceleration of workloads using the Nvidia DevicePlugin. Further, complex GPGPU workloads like Kubeflow work on CDK. That performance reflects joint efforts with Google to accelerate ML in the enterprise, providing a portable way to develop and deploy ML applications at scale. Applications built and tested with Kubeflow and CDK are perfectly transportable to Google Cloud, according to Shuttleworth.

Developers can use the new Ubuntu to create applications on their workstations, test them on private bare-metal Kubernetes with CDK, and run them across vast data sets on Google’s GKE, said Stephan Fabel, director of product management at Canonical. The resulting models and inference engines can be delivered to Ubuntu devices at the edge of the network, creating an ideal pipeline for machine learning from the workstation to rack, to cloud and device.

Snappy Improvements

The latest Ubuntu release allows desktop users to receive rapid delivery of the latest applications updates. Besides having access to typical desktop applications, software devs and enterprise IT teams can benefit from the acceleration of snaps, deployed across the desktop to the cloud.

Snaps have become a popular way to get apps on Linux. More than 3,000 snaps have been published, and millions have been installed, including official releases from Spotify, Skype, Slack and Firefox,

Snaps are fully integrated into Ubuntu GNOME 18.04 LTS and KDE Neon. Publishers deliver updates directly, and security is maintained with enhanced kernel isolation and system service mediation.

Snaps work on desktops, devices and cloud virtual machines, as well as bare-metal servers, allowing a consistent delivery mechanism for applications and frameworks.

Workstations, Cloud and IoT

Nvidia GPGPU hardware acceleration is integrated in Ubuntu 18.04 LTS cloud images and Canonical’s OpenStack and Kubernetes distributions for on-premises bare metal operations. Ubuntu 18.04 supports Kubeflow and other ML and AI workflows.

Kubeflow, the Google approach to TensorFlow on Kubernetes, is integrated into Canonical Kubernetes along with a range of CI/CD tools, and aligned with Google GKE for on-premises and on-cloud AI development.

“Having an OS that is tuned for advanced workloads such as AI and ML is critical to a high-velocity team,” said David Aronchick, product manager for Cloud AI at Google. “With the release of Ubuntu 18.04 LTS and Canonical’s collaborations to the Kubeflow project, Canonical has provided both a familiar and highly performant operating system that works everywhere.”

Software engineers and data scientists can use tools they already know, such as Ubuntu, Kubernetes and Kubeflow, and greatly accelerate their ability to deliver value for their customers, whether on-premises or in the cloud, he added.

Multiple Cloud Focus

Canonical has seen a significant adoption of Ubuntu in the cloud, apparently because it offers an alternative, said Canonical’s Fabel.

Typically, customers ask Canonical to deploy Open Stack and Kubernetes together. That is a pattern emerging as a common operational framework, he said. “Our focus is delivering Kubernetes across multiple clouds. We do that in alignment with Microsoft Azure service.”

Better Economics

Economically, Canonical sees Kubernetes as a commodity, so the company built it into Ubuntu’s support package for the enterprise. It is not an extra, according to Fabel.

“That lines up perfectly with the business model we see the public clouds adopting, where Kubernetes is a free service on top of the VM that you are paying for,” he said.

The plan is not to offer overly complex models based on old-school economic models, Fabel added, as that is not what developers really want.

“Our focus is on the most effective delivery of the new commodity infrastructure,” he noted.

Private Cloud Alternative to VMware

Canonical OpenStack delivers private cloud with significant savings over VMware and provides a modern, developer-friendly API, according to Canonical. It also has built-in support for NFV and GPGPUs. The Canonical OpenStack offering has become a reference cloud for digital transformation workloads.

Today, Ubuntu is at the heart of the world’s largest OpenStack clouds, both public and private, in key sectors such as finance, media, retail and telecommunications, Shuttleworth noted.

Other Highlights

Among Ubuntu 18.04’s benefits:

  • Containers for legacy workloads with LXD 3.0 — LXD 3.0 enables “lift-and-shift” of legacy workloads into containers for performance and density, an essential part of the enterprise container strategy.

    LXD provides “machine containers” that behave like virtual machines in that they contain a full and mutable Linux guest operating system, in this case, Ubuntu. Customers using unsupported or end-of-life Linux environments that have not received fixes for critical issues like Meltdown and Spectre can lift and shift those workloads into LXD on Ubuntu 18.04 LTS with all the latest kernel security fixes.

  • Ultrafast Ubuntu on a Windows desktop — New Hyper-V optimized images developed in collaboration with Microsoft enhance the virtual machine experience of Ubuntu in Windows.
  • Minimal desktop install — The new minimal desktop install provides only the core desktop and browser for those looking to save disk space and customize machines with their specific apps or requirements. In corporate environments, the minimal desktop serves as a base for custom desktop images, reducing the security cross-section of the platform.

Peppermint 9 Offers Some Cool New Options | Reviews

Peppermint 9 Offers Some Cool New Options

Peppermint 9, released June 22, accomplishes something most other Linux distros don’t: It melds the best components from other desktop environments and integrates them into a solid operating system.

Peppermint OS is a lightweight Ubuntu-based distribution featuring a desktop environment mashup of Xfce and LXDE components. The latest release nearly completes a process begun several upgrades ago, using more Xfce elements and fewer LXDE components.

Peppermint is a good alternative to the Linux Mint Xfce release with a sprinkling of Cinnamon to spice up the desktop a bit more. Peppermint also uses Ice — a cloud and Web application management tool — which makes the operating system refreshingly different.

A site-specific browser, or SSB, Ice lets users easily create a launcher that connects to a website with desired content or services. It enables Peppermint OS users to connect to cloud applications and Internet URLs by clicking on menu items Ice adds. It also makes it possible to run apps without constantly being tethered to the Internet.

Given its Debian and Ubuntu roots, Peppermint 9 does not offer a radical change for most users, with possible exceptions being those coming from Arch Linux, or Fedora-based or RPM-based distributions. Peppermint 9 is based on Ubuntu 18.04 Long Term Support and features only several small changes over 8, released a year ago.

Combine all of what Peppermint 9 offers, and you get a Linux distro that is familiar and comfortable to use, as well as one with a collection of tools and tweaks not duplicated elsewhere. The result is an almost hybrid distro with its own unique flavor.


Peppermint OS background images and settings menus

Peppermint OS comes with a collection of vibrant background images for the desktop and handy settings panel to configure the platform your way.


Cures Linux Lament

The availability of so many Linux desktop environments can be problematic. After reviewing old, new and renewed Linux distros every week, I often get frustrated when I find a unique and particularly interesting distro that stands apart from the many look-a-like options. I have a growing list of favorites and an equally growing collection of computers with multiple Linux OSes installed.

Selecting a distro for regular use involves making a choice of which desktop features or user interface innovations justify not having other fanciful features the chosen distro left out. Peppermint 9 makes that choice easier, thanks to the Peppermint community’s success in fusing bits and pieces of other distros into a well-oiled integrated platform.

For instance, the developer team replaced lxrandr with xfce4-display-settings for monitor settings that add functionality without weight, continuing the migration away from the few remaining LXDE components.

The Xfce Panel Switch utility now is installed by default. This makes it simple to back up and restore any custom panel configurations and switch among them.

The developers improved menu and launcher management as well. It may be a small thing, but the ability to create a new launcher with a right-click is a convenience that matters. So is being able to send any file by email with a mere right-click within the Nemo file manager.

Peppermint 9 Highlights

Its many tweaks and refinements make Peppermint 9 both delightful to experience and productive to use. Some of them resulted from the policy to migrate away from the older LXDE components. Other improvements reflect the goal of designing a better UI that combines the best computing elements in other desktops.

For instance, the Settings Panel’s system notification settings have a Do Not Disturb function. You can enable or disable notifications on a per application basis.

New Gtk themes are based on Arc but display with a few tweaks and some added color choices. Qt applications such as VLC incorporate the system Gtk theme. Gtk overlay scroll bars are enabled by default.

The Mintinstall software manage coexists with the Gnome software manager for users who want Snaps and Flatpaks. Plus, you can use the Synaptic Package Manager.

Developers switched the graphical screenshot application from pyshot to xfce4-screenshooter. The inclusion of Symlinks enables installed Snaps and Flatpaks to show up in the main menu.


Peppermint 9 Whisker menu

Peppermint’s desktop has no launch icons. Click on the main menu button to open the Whisker menu to change that.


License to Chill

The Ice concept has been part of the Peppermint ecosystem from the distro’s beginning in 2010. In fact, the developers consider it the distro’s best feature.

I am surprised that the Ice technology has not been integrated in other distros, but it is a distinguishing feature that makes the Peppermint OS more flavorful.

Ice allows Web content to function more like a standalone application window rather than a connected URL in a standard Web browser. This approach also offers the advantage of additional screen space. SSBs do not include all the functions and menus of a browser.

With the Ice app in Peppermint OS, it is easy to copy and paste a URL into Ice’s location window along with other basic information. This one-time site setup creates a launcher icon on the desktop as well as a main menu entry.

Disappointing SSB Support

What is new in version 9 is a collection of Microsoft Office Online SSBs. These are links to the free Web app version of Office, which includes Excel, Word, OneNote and PowerPoint. The Internet section of the main menu also has SSB locations for connecting to Skype, the Peppermint User Guide Online and the Peppermint Forum.

I was more enthused over using SSBs in earlier versions of Peppermint. That process is similar to configuring Android devices and Chromebooks to open a solitary Web browser window separate from other tabs in a running Web browser.

In essence, the Ice app is a glorified bookmark and menu entry-making tool. It has the appearance of being a standalone app, but it actually is an isolated Web browser window — the default browser is Firefox. You can specify other installed browsers to open an isolated window instead.

I was disappointed with the lack of more pre-installed Ice launchers in the current release. Creating launchers is simple enough, but without a prepared list of sample locations, I suspect that typical users will not bother creating their own.

Look and Feel

If you are familiar with either the Linux Mint Cinnamon or Xfce editions, you already have a feel for the Peppermint UI. At first blush, they all pretty much have the same appearance and configuration flexibility. As you use Peppermint, however, the subtle tweaks will become noticeable. You will experience the blended desktop elements.

The toolbar sits across the bottom of the screen and closely resembles the Cinnamon real estate. It is preconfigured with a workspace switcher applet set with two virtual desktops.

Right-click on the applet and select “Workspaces” to add or remove virtual workspaces. Right-click on the bottom bar itself to open a settings panel to adjust the bar and add more applets.


Peppermint 9 menu options, applets

With Peppermint 9 you can right-click on the desktop for specific menu options that let you avoid going to the control panel settings. Right-click on the bottom bar itself to open a settings panel to adjust the bar and add more applets.


Peppermint comes with a collection of vibrant background images for the desktop. It otherwise is devoid of any launch icons. Of course, you can click on the main menu button to open the Whisker menu.

Right-clicking on an application lets you place its launcher icon on the desktop, on the panel bar, or in the menu’s favorites category. You can right-click on the desktop for specific menu options that let you avoid going to the control panel settings.

Bottom Line

Peppermint 9 comes in both 64-bit and 32-bit versions so older hardware is still supported. It runs the 4.15 Kernel series.

Originally based in the U.S., the software company that developed Peppermint OS now operates out of the UK. It offers commercial versions of Peppermint OS for the enterprise as well as the free version.

Installing it is smooth, fast and hassle-free. The process is fully automated and makes dual-booting a snap.
