Can A Linux Cert Payoff?
The Linux Foundation has announced an online certification programme for entry-level system admininstration and advanced Linux software engineering professionals to help expand the global pool of Linux sysadmin and developer talent.
The foundation indicated that it established the certification programme because there’s increasing demand for staff in the IT industry, saying, “Demand for experienced Linux professionals continues to grow, with this year’s Linux Jobs Report showing that managers are prioritizing Linux hires and paying more for this talent.
“Because Linux runs today’s global technology infrastructure, companies around the world are looking for more Linux professionals, yet most hiring managers say that finding Linux talent is difficult.”
Linux Foundation executive director Jim Zemlin said, “Our mission is to address the demand for Linux that the industry is currently experiencing. We are making our training [programme] and Linux certification more accessible to users worldwide, since talent isn’t confined to one geography or one distribution.
“Our new Certification [Programme] will enable employers to easily identify Linux talent when hiring and uncover the best of the best. We think Linux professionals worldwide will want to proudly showcase their skills through these certifications and that these certificates will become a hallmark of quality throughout our industry.”
In an innovative departure from other Linux certification testing offered by a number of Linux distribution vendors and training firms, the foundation said, “The new Certification [Programme] exams and designations for Linux Foundation Certified System Administrator (LFCS) and Linux Foundation Certified Engineer (LFCE) will demonstrate that users are technically competent through a groundbreaking, performance-based exam that is available online, from anywhere and at any time.”
The exams are customised somewhat to accommodate technical differences that exist between three major Linux distributions that are characteristic of those usually encountered by Linux professionals working in the IT industry. Exam takers can choose between CentOS, openSUSE or Ubuntu, a derivative of Debian.
“The Linux Foundation’s certification [programme] will open new doors for Linux professionals who need a way to demonstrate their know-how and put them ahead of the rest,” said Ubuntu founder Mark Shuttleworth.
Those who want to look into acquiring the LFCS and LFCE certifications can visit the The Linux Foundation website where it offers the exams, as well as training to prepare for them. The exams are priced at $300, but apparently they are on special introductory offer for $50.
The Linux Foundation is a nonprofit organization dedicated to accelerating the growth of Linux and collaborative development. It is supported by a diverse roster of almost all of the largest IT companies in the world except Microsoft.
RedHat Goes Atomic
The Red Hat Summit kicked off in San Francisco on Tuesday, and continued today with a raft of announcements.
Red Hat launched a new fork of Red Hat Enterprise Linux (RHEL) with the title “Atomic Host”. The new version is stripped down to enable lightweight deployment of software containers. Although the mainline edition also support software containers, this lightweight version improves portability.
This is part of a wider Red Hat initiative, Project Atomic, which also sees virtualisation platform Docker updated as part of the ongoing partnership between the two organisations.
Red Hat also announced a release candidate (RC) for Red Hat Enterprise Linux 7. The beta version has already been downloaded 10,000 times. The Atomic Host fork is included in the RC.
Topping all that is the news that Red Hat’s latest stable release, RHEL 6.5 has been deployed at the Organisation for European Nuclear Research – better known as CERN.
The European laboratory, which houses the Large Hadron Collider (LHC) and was birthplace of the World Wide Web has rolled out the latest versions of Red Hat Enterprise Linux, Red Hat Enterprise Virtualisation and Red Hat Technical Account Management. Although Red Hat has a long history with CERN, this has been a major rollout for the facility.
The logging server of the LHC is one of the areas covered by the rollout, as are the financial and human resources databases.
The infrastructure comprises a series of dual socket servers, virtualised on Dell Poweredge M610 servers with up to 256GB RAM per server and full redundancy to prevent the loss of mission critical data.
Niko Neufeld, deputy project leader at the Large Hadron Collider, said, “Our LHCb experiment requires a powerful, very reliable and highly available IT environment for controlling and monitoring our 70 million CHF detectors. Red Hat Enterprise Virtualization is at the core of our virtualized infrastructure and complies with our stringent requirements.”
Other news from the conference includes the launch of Openshift Marketplace, allowing customers to try solutions for cloud applications, and the release of Red Hat Jboss Fuse 6.1 and Red Hat Jboss A-MQ 6.1, which are standards based integration and messaging products designed to manage everything from cloud computing to the Internet of Things.
Ubuntu Cross-Platform Delayed
Ubuntu will not offer cross-platform apps as soon as it had hoped.
Canonical had raised hopes that its plan for Ubuntu to span PCs and mobile devices would be realised with the upcoming Ubuntu 14.04 release, providing a write-once, run-on-many template similar to that planned by Google for its Chrome OS and Android app convergence.
This is already possible on paper and the infrastructure is in place on smartphone and tablet versions of Ubuntu through its new Unity 8 user interface.
However, Canonical has decided to postpone the rollout of Unity 8 for desktop machines, citing security concerns, and it will now not appear along with the Mir display server this coming autumn.
This will apply only to apps in the Ubuntu store, and in the true spirit of open source, anyone choosing to step outside that ecosystem will be able to test the converged Ubuntu before then.
Ubuntu community manager Jono Bacon told Ars Technica, “We don’t plan on shipping apps in the new converged store on the desktop until Unity 8 and Mir lands.
“The reason is that we use app insulation to (a) run apps securely and (b) not require manual reviews (so we can speed up the time to get apps in the store). With our plan to move to Mir, our app insulation doesn’t currently insulate against X apps sniffing events in other X apps. As such, while Ubuntu SDK apps in click packages will run on today’s Unity 7 desktop, we don’t want to make them readily available to users until we ship Mir and have this final security consideration in place.
“Now, if a core-dev or motu wants to manually review an Ubuntu SDK app and ship it in the normal main/universe archives, the security concern is then taken care of with a manual review, but we are not recommending this workflow due to the strain of manual reviews.”
As well as the aforementioned security issues, there are still concerns that cross-platform apps don’t look quite as good on the desktop as native desktop versions and the intervening six months will be used to polish the user experience.
Getting the holistic experience right is essential for Ubuntu in order to attract OEMs to the converged operating system. Attempts to crowdfund its own Ubuntu handset fell short of its ambitious $20m target, despite raising $10.2 million, the single largest crowdfunding total to date.
Red Hat Releases Linux E-Beta
Red Hat has made available a beta of Red Hat Enterprise Linux 7 (RHEL 7) for testers, just weeks after the final release of RHEL 6.5 to customers.
RHEL 7 is aimed at meeting the requirements of future applications as well as delivering scalability and performance to power cloud infrastructure and enterprise data centers.
Available to download now, the RHEL 7 beta introduces a number of enhancements, including better support for Linux Containers, in-place upgrades, XFS as the default file system, improved networking support and improved compatibility with Windows networks.
Inviting customers, partners, and members of the public to download the RHEL 7 beta and provide feedback, Red Hat is promoting the upcoming version as its most ambitious release to date. The code is based on Red Hat’s community developed Fedora 19 distribution of Linux and the upstream Linux 3.10 kernel, the firm said.
“Red Hat Enterprise Linux 7 is designed to provide the underpinning for future application architectures while delivering the flexibility, scalability, and performance needed to deploy across bare metal, virtual machines, and cloud infrastructure,” Senior Product Marketing Manager Kimberly Craven wrote on the Red Hat Enterprise Linux blog.
These improvements address a number of key areas, including virtualisation, management and interoperability.
Linux Containers, for example, was partially supported in RHEL 6.5, but this release enables applications to be created and deployed using Linux Container technology, such as the Docker tool. Containers offers operating system level virtualisation, which provides isolation between applications without the overhead of virtualising the entire server.
Red Hat said it is now supporting an in-place upgrade feature for common server deployment types. This will allow customers to migrate existing RHEL 6.5 systems to RHEL 7 without downtime.
RHEL 7 also makes the switch to XFS as its default file system, supporting file configurations up to 500TB, while ext4 file systems are now supported up to 50TB in size and B-tree file system (btrfs) implementations are available for users to test.
Interoperability with Windows has also been improved, with Red Hat now including the ability to bridge Windows and Linux infrastructure by integrating RHEL 7 and Samba 4.1 with Microsoft Active Directory domains. Red Hat Enterprise Linux Identity Management can also be deployed in a parallel trust zone alongside Active Directory, the firm said.
On the networking side, RHEL 7 provides support for 40Gbps Ethernet, along with improved channel bonding, TCP performance improvements and low latency socket poll support.
Other enhancements include support for very large scale storage configurations, including enterprise storage arrays, and uniform management tools for networking, storage, file systems, identities and security using the OpenLMI framework.
Is Ubuntu Linux Spyware?
Richard Stallman has asked a South American free software association not to promote Ubuntu Linux at its events because it “spies on its users” by collecting its users’ desktop search activity and selling the data to Amazon.
Canonical released Ubuntu 12.10 last October with Amazon search integrated into its Dash desktop search function.
Although Ubuntu users can opt out and Canonical claims it anonymises users’ search information before sending it to Amazon, the change resulted in Ubuntu users being shown Amazon ads in response to desktop search queries.
The ‘feature’ has attracted a lot of criticism and might have led some users to defect to other Linux distributions.
When Stallman’s request was denied by the FLISOL event organiser with the excuse that it would limit user freedom of choice, Stallman fired off a response to the organisation’s entire mailing list on Sunday. Parts of his email are quoted below, as translated by Groklaw.
“The issue I raise is about what should happen at FLISOL events. Give away copies of Ubuntu or not? Promote Ubuntu or no? I asked the organisers of the event that they, as a policy, not distribute or promote Ubuntu.
“Freedom of users is something else, and there isn’t a conflict between a user’s freedom and my request. If someone decides to install Ubuntu, I would consider it a mistake, but it’s his own choice to do it. What I ask is that you don’t participate, help or suggest that he do it. I didn’t request that you block him from doing so.
“As a matter of principle, I don’t believe anyone has a right, morally, to distribute proprietary software, that is, software that deprives the users of freedom. When the user controls his own software, he can install what he wants and no one can stop him. But today’s issue isn’t about him, what he does, but rather what you do with him.”
As Stallman sent his email only yesterday, it’s not yet known whether FLISOL has reconsidered promoting Ubuntu at its free software events.
These points might seem like splitting hairs, but apparently Richard Stallman – the author of the GNU General Public Licence (GPL), as well as the founder and president of the Free Software Foundation – is serious about them.
