Ubuntu doubles down on Unity, will focus on mobile and the cloud in 2013

Ubuntu doubles down on Unity, will focus on mobile and the cloud in 2013

In less than a decade, Ubuntu has become the most well-known desktop Linux variant. With its heavy focus on user interface and usability, it’s easy to see why Ubuntu has become a popular introduction to the world of Linux. Recently, the developers have switched away from traditional interfaces to a more streamlined UI called Unity. The new look alongside integration with Amazon search from the desktop have raised the ire of a number of Linux diehards. Mark Shuttleworth, founder of Ubuntu, has recently made a blog post explaining the plans for Ubuntu in 2013. Anyone expecting a change of heart about Canonical’s recent UI and UX decisions is in for some disappointment.

Shuttleworth addresses his detractors by saying, “If you’ve been arguing over software licenses for the best part of 15 years then you would probably be fine with whatever came before Ubuntu.” Essentially, he dismisses the hardcore Linux enthusiast by implying Ubuntu isn’t designed for them. Instead, he is focused on Ubuntu becoming approachable and usable by the largest number of people. While the goal of making a free and open-source operating system for the whole world is incredibly admirable, it shouldn’t come at the expense of the community that has made Ubuntu into the juggernaut it currently is.

The South African millionaire continues to explain that in the coming months, Ubuntu development will be focused heavily on moving into the tablet and smartphone space while simultaneously focusing on cloud computing. While this is undoubtedly the best way forward, it will obviously rub some Linux enthusiasts the wrong way. A vocal minority of Linux users and developers are stuck in a 1990s mindset where the desktop is king, and everything should be focused on power users. With that sort of thinking, Linux has never become a substantial player in the desktop space — but taking its powerful underpinnings and making it approachable has made Android one of the most widely used consumer operating systems in the world. The idealism underpinning Ubuntu hasn’t always been implemented perfectly, but Canonical is making huge strides in usability. Hands down, Ubuntu is the most interesting and progressive consumer oriented Linux distribution available today.

It would be ridiculous to think Ubuntu would stop iterating on the idea of a user-friendly Linux distro just to please some uppity neckbeards. However, it would be nice if the Canonical leadership weren’t so openly hostile towards their detractors. Instead of eye rolling and explaining that Ubuntu isn’t made with them in mind, Canonical should embrace the vocal minority. Throw them a bone by highlighting how easy it is to switch to vanilla Gnome, KDE, or Xfce, and embrace how diverse the Linux community can be. In turn, the old school Linux fans shouldn’t expect Ubuntu to stagnate simply for their comfort. The times they are a-changin’, folks.

Top 10 most popular Linux server distributions

Top 10 Linux server distributions are listed here

Everyone knows that many data center servers are running Linux, this can save a lot of license fees and maintenance costs. There are numerous Linux distributions now available and the problem is how to chose the best ? Here are the top 10 most popular Linux server distributions, perhaps we have included few which you probably have not heard of.

In the following list there is no particular ranking , We have written the list based on the main criteria: ease of use, with commercial support and have the data center reliability.

Ubuntu: Linux-related products, as almost the entire list, based on Debian to Ubuntu very special and unique. From its easy installation to excellent hardware recovery, to the level of world-class commercial support, regardless of where on the one hand, Ubuntu is beyond all other versions, and let them catch up.

Red Hat: Red Hat Enterprise Linux (RHEL) from the shouting of “almost no Linux company can do” to the current search for the data center has become a major force storage shelf areas. Linux is the darling of large enterprises around the world, Red Hat’s spirit of innovation and continuous support for it won lot many repeated customers.

SUSE: Novell’s SUSE is known for its stability and ease of maintenance . In addition, it is designed for those who do not have time and patience to wait for a long troubleshooting telephone customers to support Novell’s all-weather rapid response. Moreover, Novell’s consulting team will help you a to chieve your service level agreements.

Mandriva: The structure is reasonable to incredible Linux distributions received good response from France ,Europe and South America w. As its website claims, it is a worldwide Linux vendors. The name and structure from Mandriva Mandrake Linux and Connectiva Linux.

Xandros: If you prefer Microsoft-related Linux version, then Xandros would be a good choice. Aside rumors did not say, Xandros and Microsoft did during the so-called insiders in technology cooperation. This means that they are to compete at the same time also give cooperation. If you want a unique perspective on the depth of understanding, please visit the website of Xandros.

Slackware: Although it is not having the relationship with the commercial version of big, but it is provided with several support has been paid to maintain relations of cooperation. As one of the earliest available version, Slackware has a broad and loyal fan base. It’s developers regularly release new versions.

Debian: Debian do not think I listed here are pieces of strange things. Indeed, Debian offers no formal business support, but you can consult it in the world to connect Debian consultants page. The mother than other Linux versions such as Ubuntu, Linux Mint, and Vyatta is concerned, Debian is more developed sub-version.

Vyatta: PC operating system compared to, Vyatta is more in the family of router and firewall. But if you want a commercial driver version to support these applications, Vyatta can guarantee your communications needs.

latform buys HP’s message passing interface

latform buys HP’s message passing interface

Platform Computing, which has carved out a niche for itself managing supercomputer clusters and dispatching applications on HPC gear, has been expanding up the stack. It continued this process today when it acquired the HP-MPI stack created by HP for its own servers, as well as others used in HPC clusters.

MPI, short for message passing interface, is the protocol used to parse-up jobs and spread around data as a cluster runs a parallelised application. It’s the backbone of the cluster and is therefore a key component of any application. There are plenty of MPI stacks available, some of them open source, some of them not, and all are tuned for different architectures or spanning multiple types of platforms and network interconnects.

To help build up its business – which got its start with the Load Sharing Facility (LSF) tool for managing gridded applications decades ago – Platform has open-sourced its software and contributed to key open source cluster-management projects, while at the same time buying up MPI stacks and adding other goodies into its tools.

Platform Cluster Manager – formerly known as the Open Cluster Stack and in its fifth release – includes an open source implementation of the LSF job-scheduling tool called Lava and developed under a project called Kusu. OCS also includes Nagios for system monitoring, Cacti for node and cluster monitoring, Ganglia for workload monitoring, and other software that’s needed to run an x64-based supercomputer cluster based on Linux.

HP started reselling its own bundle of the Platform cluster tools, called Platform HPC for Insight Control Environment for Linux, in March. This followed Red Hat’s own Red Hat HPC Solution, which debuted in October 2008, and Dell’s own twist on the Platform stack, called OCS Del Edition, which came out two weeks later. Companies can also download the Cluster Manager tools from Platform directly and pay for support contracts if they want to build their own HPC setups.

To make its cluster tools more useful and relevant, Platform bought the HPC management software stack from Scali in October 2007. Then in August 2008 it acquired the Scali-MPI stack to weave it into its cluster tools.

Just last week, Platform inked a deal with nVidia that will see the CUDA programming environment for Tesla GPU co-processors incorporated into its cluster management tools. This means that both Cluster Manager and LSF can seamlessly dispatch work to Tesla engines, just as it can dispatch work to x64 processor cores inside a cluster.

While the Scali-MPI stack that Platform acquired last year was tuned for Linux, it had some limitations in that it was only supported by a half-dozen independent software vendors. According to Tripp Purvis, VP of business development at Platform, the company had only done a little work making Scali-MPI work with Windows and had done no work porting it to various flavours of Unix.

BackupPC – A handy Linux backup tool

BackupPC – A handy Linux backup tool

Backing up Linux machines can be challenging, especially for storage/backup administrators who are used to working primarily with Windows. Part of the reason for this (aside from the obvious differences between Linux and Windows) is that there are so many different flavors of Linux such as Red Hat, Ubuntu, HP Linux, SUSE, etc. That means that a backup method that works well on one version or brand of Linux may not produce the same results on another type of Linux deployment.

One really interesting enterprise-class backup product that I have found for Linux is BackupPC. Like many Linux applications, BackupPC is open source and downloadable from the Internet, which is always a plus.

What makes BackupPC unique

There are a few different things about BackupPC that make it worth checking out. For starters, BackupPC is a disk-to-disk (D2D) backup solution. Like Microsoft’s Data Protection Manager, it allows you to create backups of multiple machines, and save the data that you have backed up to a hard drive. But the similarities end there.

If you have ever used Data Protection Manager, then you know that it creates a dedicated volume within your storage pool for each machine that is being protected. An agent component on the target machine ensures that the target is backed up on a periodic basis.

BackupPC doesn’t require an agent (or any other software component) to be installed on the machines that are being backed up. More importantly, it makes much more efficient use of its storage pool than Data Protection Manager does. Suppose, for example, that you are using Data Protection Manager to back up five different Windows Servers. In such a case, you would have five dedicated volumes, each of which would likely contain copies of the exact same Windows system files.

Single-instance storage

BackupPC uses single-instance storage, but does so across multiple targets. For example, if you have five machines that all have the same version of a particular system file, then that file is only stored once within the storage pool. This has the potential to save a tremendous amount of hard disk space.
