Ubuntu 13.04 and paving the way to 14.04 LTS

On the cloud infrastructure side, the expansion of our ecosystem plays well into the diversification we see in technology choices along the cloud stack. Ubuntu now works seamlessly with various products such as Ceph for storage, Floodlight for SDN, and the Canonical-VMWare collaboration links OpenStack compute (Nova) to the ESX hypervisor. Offering a ‘High Availability’ deployment configuration for core OpenStack components such as RabbitMQ and MySQL helps meet service provider requirements for maximum uptime and reliability. We expect this to be extended to other Juju charms in the near future, offering a complete HA environment for cloud infrastructure.



Window snapping, popularised by the ‘Aero Snap’ feature of Windows 7, is a handy way to quickly display two applications side-by-side without overlapping, or maximise a window without needing to click a button.

For 13.04 a bit of attention has been given to the animation shown on screen to tell you that ‘you’re about to snap’. Developers have changed its appearance from that of a generic orange box spreading outwards to a semi-transparent copy of the window about to be snapped.

New Unity Preview Animations

Unity Previews, introduced last year in Ubuntu 12.10, are a great way to see more information about a search result without needing to open it up fully.

For the latest release the preview reveal animation has been tweaked, and applications icons at the edges of the preview “ghosted” save for the one being previewed.
Ubuntu desktop is the centralised ‘Online Accounts‘ dashboard.
Originally planned to arrive on the desktop last year is this – the new Ubuntu One Sync Menu. With a single click you can see whether you’re online; share a file; or check the status of recently uploaded files.
Ubuntu’s Bluetooth panel menu has been jazzed up with new toggle for turning on/off Bluetooth and visibility.
A core goal for Ubuntu 13.04 is to get Ubuntu running on a Nexus 7 tablet. To be clear, this is not going to be a tablet Unity interface running on the 8/16GB Nexus 7ubuntunexus7-large_001
But thanks to an inspired decision last October, Ubuntu 13.04 will use a mobile device as reference for tuning the core of Ubuntu. This will result into a smooth, snappy, and faster experience.

Mastering Debian 6 – One

Welcome to the world of GNU/Linux, liberating the computing desktop from the shackles of proprietary interests.

What’s In A Name

The phrase Microsoft Windows (and less informatively just Windows) usually refers to the whole of the popular operating systems, irrespective of which version of Microsoft Windows is being run, unless the version is important. But Microsoft Windows is just one of many windowing systems available, and indeed, Microsoft Windows came on to the screen rather later than the pioneering Apple Macintosh windowing system and the Unix windowing systems. We will simply refer to all varieties of Microsoft’s windowing systems (Windows 95/98/NT/2000/XP) as MS/Windows. If the particular version is important it will be referred to as MS/Windows/XP, for example.

We use the phrase GNU/Linux to refer to the GNU environment and the GNU and other applications running in that environment on top of the Linux operating system kernel. Similarly, GNU/Hurd refers to the GNU environment and the GNU and other applications running in that environment on top of the GNU Hurd operating system kernel.

Debian is a complete distribution which includes many applications based around a particular choice of operating system kernel (usually either GNU/Linux or GNU/Hurd). Where the particular kernel is not important we will refer to whole system as Debian.

The common windowing system used in Debian is a separate, but integral, component that we will refer to as the X Window System.

How to Download the CD Image ?
You may be wondering why you should go through a process of building a CD image yourself rather than simply downloading the appropriate images from a Debian CD image mirror somewhere. The answer has been that there are many Debian mirrors world-wide that store the complete collection of Debian packages. If these mirrors were to also store the CD images the extra space required is essentially wasted space and so many of the Debian mirrors do not keep the CD images.

There are a smaller number of Debian hosts on the Internet that do maintain CD images. These hosts are often not local and the amount of bandwidth required to download the images from these smaller number of mirrors is quite significant.

According to the Debian GNU/Linux CD Images Frequently Asked Questions page (http://cdimage.debian.org/faq.html) by using a distributed approach based on the network of Debian package mirrors the required bandwidth to the CD image mirrors is reduced by over 99%!

Nonetheless, today you may find local Debian hosts mirroring the CD images also. If that is the case then it is easier to simply download the actual images rather than building the images as described in the rest of this chapter. In Australia, for example, the primary Debian mirror also mirrors the CD images (from http://cdimage.debian.org. So for those in .au and .nz it is perhaps easiest to simply download one of the following:
$ wget http://mirror.aarnet.edu.au/pub/debian-cd/3.0_r1/i386/debian-30r1-i386-binary-1_NONUS.iso
$ wget http://mirror.aarnet.edu.au/pub/debian-cd/3.0_r1/i386/debian-30r1-i386-binary-1.iso
Then burn the image to CD using whatever tools you have at your disposal. For release 3 there are 7 CDs. The NONUS alternative (which contains items that can not be exported directly from the US) is only relevant to the first CD.
