eBook: Certified Ubuntu Cloud Guest - front page

Download eBook ›

Ubuntu has a long history in the cloud. It is the world’s number one platform for deployments of OpenStack – the world’s leading cloud infrastructure platform. And it is the number one guest operating system, with more images running on the leading public clouds than all other operating systems combined. Ubuntu is a free operating system; in fact anyone can download an image, whenever they want.

So why are certified images so important?

Certified images are essential for organisations and individuals that require the highest level of security and reliability. Whether it’s an unforeseen incompatibility that requires extensive developer resource to fix, or a security vulnerability that impedes operations while you wait for a patch, the implications downtime and vulnerabilities can often be measured in millions of dollars.

Certified Ubuntu Cloud Guest images give you the peace of mind you need to run mission critical workloads on any of the world’s leading public clouds. They are supported by Canonical, the company behind Ubuntu, ensuring that updated images are delivered automatically and that bugs and vulnerabilities are fixed fast. Additionally, as the images are standardised, they help you avoid being locked into the services of one infrastructure supplier. They ensure that you are always running on the most up-to-date version of Ubuntu, so you can rely on complete compatibility with other up-to-date Ubuntu images, whether they’re running on your developers’ laptops or other public clouds.

An enormous amount of work goes into creating and maintaining certified images, because it’s necessary to ensure that the best Ubuntu experience is available to everyone. With a cutting-edge toolset and enterprise commercial support available directly from the vendor, there’s no better choice in the cloud – whatever the cloud. And if you’re considering using the services of a public cloud provider who currently doesn’t offer certified Ubuntu images, ask them to talk to Canonical today about joining the CPC program and offering all the benefits of Ubuntu certified images to their customers. Because in today’s competitive cloud world, you need all the advantages you can get, whether you’re a startup or a stock market titan.

Ubuntu Touch’s Web Browser to Improve the Google Hangouts Experience in OTA-11

The long-anticipated OTA-11 update for Ubuntu Phone and Ubuntu Tablet devices is just around the corner, and today we’ll have a quick look at what’s coming in the Web Browser app.
Canonical’s technical lead in the product strategy division, apps team, Mr. Olivier Tilloy, has published details about some of the features included in the Web Browser app of the Ubuntu Touch mobile operating system, which will be added as part of the soon-to-be-released OTA-11 update.
Therefore, the updated Web Browser app has promised to improve the Google Hangouts experience for all form factors, including Canonical’s new Ubuntu Tablet, the BQ Aquaris M10 Ubuntu Edition, and it looks like the media permission request dialog has been redesigned to be more user-friendly.
Continuing, the Web Browser app will now visually identify the list of items that are being used for opening new pages in the Ubuntu Settings app with a progression symbol, it will also properly handle window-level keyboard shortcuts, and further polish the memory-pressure handler used for unloading tabs running in the background.

NetOS Enterprise Linux 8 Promises to Be a Worthy Alternative to Chrome OS

Designed as a replacement for the Linux kernel-based Chrome OS or Chromium OS operating systems, Black Lab Software’s upcoming NetOS distribution is using the same technologies that have been implemented in the Enterprise Edition of the Black Lab Linux OS.
That’s why it’s called NetOS Enterprise, and the first release is now in development, based on the upcoming Black Lab Enterprise Linux 8 operating system, which is also in heavy development these days. So as one might expect, NetOS promises to be a worthy replacement for Chrome OS or Chromium OS web-centric operating systems.
Being a web-centric operating system, NetOS includes dozens of Web Apps. Therefore, users will be able to access online services like Google Docs, Google Maps, Google Play Music, Gmail, Goole Apps for Business, Microsoft Office Online, Oracle Cloud Apps, Microsoft Azure, Slack, Apple iCloud, and Outlook Web Access.

Managing Multiple Sound Sources in Android with Audio Focus

Sound is a great way to grab user attention, give interface feedback or immerse a player in a game. Imagine if multiple apps all tried to play sounds at the same time. This would result in an unintelligible cacophony and make users reach for the mute button. Android provides a simple API to play music and audio effects and manage different sources. The Android audio focus API lets an app request ‘audio focus’ and lets the app know if it has lost focus so it can react. In this tutorial I will show how to use these APIs in your own apps.
You can find the final code for this tutorial on GitHub.

Birds Linux 8.0, the Distro for Students, Launches with Kernel 4.5, Tor Browser

Birds Linux creator Francesco Milesi has informed about the immediate availability of a
major update to his open-source computer operating system, Birds Linux 8.0.
Birds Linux 8.0 has been in development for the past three months, during which the developer has managed to update most of the core components to their latest versions. For example, the distribution is now powered by a kernel from the Linux 4.5 series and includes the LibreOffice 5.1.2 office suite.
It also looks like Birds Linux 8.0 release switches from the Xfce 4.12 desktop environment, which was used in the previous version of the OS, to the GNOME 3 desktop. It thus provided users with the GNOME 3.18.4 packages, along with the latest applications designed for students, including Budgie Calc, Budgie Zero, Wren Matrix, and Hoopoe.

Nvidia 361.45.11 Graphics Driver Released for Linux, FreeBSD and Solaris Systems

Nvidia has released a new long-lived graphics drivers for Unix users, version 361.45.11, available now for GNU/Linux, FreeBSD, and Solaris operating systems.
Nvidia 361.45.11 comes as an update to the previous long-lived release, version 361.42, bringing support for the Nvidia Quadro M5500 graphics card for notebooks. It also adds a minimum requirement of Linux kernel 2.6.32 to nvidia-uvm.ko, the Nvidia Unified Virtual Memory kernel module, a change that also first introduced as part of the Nvidia 367.18 Beta build announced last week.
Users and package maintainers are being informed that if they attempt to compile the nvidia-uvm.ko kernel module on a Linux kernel older than 2.6.32, which reached end of life a couple of months ago, the result will be a stub kernel module that won’t provide them with any functionality. However, almost no GNU/Linux operating system on the market is using kernel packages that old.

4 Notable Security Upgrades Coming to Android N

Android is the world’s largest and most popular mobile operating system, by far. But popularity, and its openness, have security and privacy trade-offs. At this year’s Google I/O developer conference, we got a look at some of the features keeping us safe in the very near future.
One of the biggest changes in Android N’s security is the new direct boot. In a nutshell, this allows your phone to update, reboot, and still be able to wake you up in the morning.
Google is rolling out a new way to update your phone. And the most noticeable thing is that you probably won’t notice it. Taking a page from Chrome OS, Android N will seamlessly apply software updates automatically and without taking what feels like a lifetime to optimize all the apps on your phone.
Nearly a year after Stagefright was disclosed, there has yet to be a single attack. While one could say this demonstrates that it was too obscure and exotic an exploit to be practical, it has had some very real and positive consequences for users. The new update system and retooling of Android’s media innards can only be good.
When it comes to user data like what’s shared with Google through the Google Photos app or in the future with the Google assistant, these results are only for users. Google’s search chief John Giannandrea clarified further, saying that no photo information, not even in aggregate, is shared with advertisers.

How to add more VPN setup options on your Ubuntu Touch device

At some point, you’re probably going to need a VPN. If you happen to be using a Ubuntu Touch device, you’ll be glad to know that the necessary systems for adding a VPN connection are in place. However, depending upon the VPN you connect to, the out-of-the-box configuration might not be enough. But, this is Linux, so naturally you
can add the necessary options.
Adding the new options requires installing what is called a click package. In order to do that, you will first have to install the Terminal app from the Ubuntu Store.
