MySQL’s co-founders are combining forces against Oracle with an independent organization to further the MariaDB fork started by Monty Widenius.The MariaDB Foundation has been announced by David Axmark, Allan Larsson and Widenius with founding members also including SkySQL chief executive Patrik Sallner, the co-founder of MySQL support specialist Percona Peter Zaitsev, and Dan Shearer of the OpenChange and Samba teams.
The Foundation, which has applied for non-profit status in the US, has received €1m in initial backing. The founders will appoint a board and confirm bylaws next February.Axmark said in a statement that MariaDB continues the work the trio started 18 years ago with MySQL, with code maintained by the same dedicated core team.“The time is right for an independent organization to safeguard the interests of MariaDB users and developers,” he said.The Foundation will review, merge, test and release changes to MariaDB and provide and infrastructure for the project and developer communities.The Foundation described its mission to:“Improve database technology, including standards implementation, interoperability with other databases, and building bridges to other types of database such as transactional and NoSQL.”
The Foundation didn’t mention Oracle specifically or in a competitive way, but it didn’t need to. Widenius has been a vocal critic of Oracle’s ownership of MySQL, speaking out against proprietary extensions that aren’t being added to the free code base, critical of what he claims is poor-quality MySQL code emanating from Oracle, and warning that Oracle will break promises it made to European regulators in 2009 over the future licensing and development of the database he helped start.
In an interview with The Reg last week, Widenius said he feared for the future of MySQL and for forks like MariaDB that he said are getting cut off by Oracle from the main code base. He fears a permanent, damaging split.Widenius left MySQL's previous owner Sun Microsystems in 2009 before the Oracle deal to buy the struggling server maker was closed. He founded MariaDB the same year and since then his MySQL has been largely maintained by his own company Widenius’ Monty Program, with companies like SkySQL supporting customers use of MariaDB and MySQL. Both hired large numbers of the MySQL engineering team who left Oracle after the Sun acquisition.
Now, however, there seems to be a determined effort to spin up MariaDB into something along the lines of an independent and broadly supported project that builds the kind of critical mass that can turn MariaDB into the new MySQL.Its path is well trodden in the open-source world against Oracle. Both the Jenkins project and the Document Foundation were created to run – respectively – forks of the Hudson continuous integration tool and the Open Office suite – Libre Office - after their new owner Oracle had claimed total ownership over their names and their development.
Oracle’s decision forced the majority of the Hudson community and Open Office members to walk out and to create their new projects, that were mirrors of the existing projects with different names and most of the same members.Stung by this, Oracle has since passed Hudson to Eclipse and Open Office to Apache. Both Jenkins and Libre Office, though, have continued to thrive, draining support and use from the original efforts.

News and Update : Japanese team targets 24Tbps optical fiber by 2014
Three of Japan's tech giants will work together to increase data transmission speeds over optical fiber, aiming for 400Gbps per channel by 2014.Fujitsu, NTT and NEC said Tuesday they will aim to combine 60 channels using the new technology, to achieve a total data transmission rate of around 24Tbps over a single optical fiber. The companies said they will advance current techniques for multiplexing and modulation of signals, and tackle the degradation of optic signals over large distances.
In addition to brute speed, an obvious requirement as more data is exchanged online, the companies said they would try to make the new network technology as adaptable as possible to handle sudden fluctuations and changes in the network. The earthquakes that regularly rock Japan are a major test for its networks, both because of the physical damage they cause and the sudden spikes in traffic that follow as the population tries to connect and get the latest news.
A major goal of the project will be to slash power consumption to less than half of that of technologies in use today, mainly by cutting down on the amount of hardware required, the companies said in a joint news release. They will also aim to develop a single device that can both modulate and demodulate traffic, for more overall network flexibility.
Faster fiber speeds have been achieved in the past under research conditions. NTT announced it set a world record in September when it hit one petabyte per second in transfers over a single 50-kilometer fiber, which it said is the equivalent of sending 5,000 two-hour high-definition videos per second.
The same companies previously teamed up, starting in 2009, to develop transmission technology that can yield 100Gbps per channel. A product based on that research went on sale earlier this year, and the companies said their chip implementation for converting signals at those speeds is the global market leader.
The new research will be sponsored by Japan's Ministry of Internal Affairs and Communications as part of a larger project to promote Japanese network technology. The government's "Research and Development Project for the Ultra-high Speed and Green Photonic Networks" is partly aimed at establishing networks that are fast and flexible enough to quickly recover when base stations are knocked out by large-scale natural disasters.

Linux : Ubuntu 13.04 daily build now available
Development marches on for Canonical, and not a few weeks after the release of Ubuntu 12.10, the first live daily builds for 13.04 are already being made available. The ISOs will currently work on x86, x86_64, PowerPC, Power5, and OMAP4 systems.Of course, as a pre-beta build, this is for development purposes only. Canonical recently announced that they will be dropping the Alpha releases from Ubuntu, so these will also be the only versions of Raring Ringtail until the beta is released in a few months time.
You can grab the ISOs from the : http://cdimage.ubuntu.com/daily-live/current/

Open Source Software : Dreamworks studio animation using open sources
Announced nearly four months ago, 3D animation house Dreamworks, best known for movies like Shrek and How To Train Your Dragon, have finally released some of their code and tools in open source. OpenVDB is the result of this, and contains technology used in their latest film Rise of the Guardians.Announced nearly four months ago, 3D animation house Dreamworks, best known for movies like Shrek and How To Train Your Dragon, have finally released some of their code and tools in open source.OpenVDB is the result of this, and contains technology used in their latest film Rise of the Guardians.
OpenVDB is an open source C++ library comprising a novel hierarchical data structure and a suite of tools for the efficient storage and manipulation of sparse volumetric data discretized on three-dimensional grids. It is developed and maintained by DreamWorks Animation for use in volumetric applications typically encountered in feature film production. Apparently, in Laymen’s terms, this means it handles smoke and other environmental features to make sure they properly fill the space.

RHEV Linux : Closer to vSphere and Hyper-V
Open source software application provider Red Hat has released an update to its Enterprise Virtualization platform, bringing it to version 3.1. This is the first major refresh to the platform since the Red Hat Enterprise Virtualization (RHEV) 3.0 release back in January of this year.With the announcement of RHEV 3.1, Red Hat moves up a few more rungs on the enterprise-ready virtualization ladder and narrows the gap with key competitor virtualization platforms from VMware and Microsoft. According to Red Hat's statement, the 3.1 release brings with it a series of compelling new features to enhance its scalability, user administration and management interface, networking, storage, and virtual desktop functionality.
Red Hat is positioning its virtualization offering as the "only mission-critical end-to-end, open source virtualization infrastructure designed for enterprise users that is available today." To show off its raw power, Red Hat points to the fact that the platform's Kernel-based Virtual Machine (KVM) hypervisor currently holds 19 of the 27 published SPECvirt_sc2010 performance benchmarks. That includes the best 2- and 4-socket scores, perhaps the most common host server type, as well as the only published 8-socket scores, showing off enterprise readiness for large organizations.
Red Hat also claims that its virtualization platform pricing is 50 to 70 percent less than alternative solutions currently on the market, giving RHEV a significant economic advantage over other players. It seems Microsoft isn't the only virtualization vendor playing the pricing card against the competition.Some of the features found in Red Hat Enterprise Virtualization 3.1 include a new and improved user interface, an improved cross-platform Web administration portal, an updated reporting dashboard, and new networking capabilities.RHEV 3.1 also continues to improve on the hypervisor platform's scalability by increasing the total number of guest virtual machines each host server can run. With this latest release, RHEV can support up to 160 logical CPUs, up from 64 in the previous release. It also increases support for up to 2TB of memory per virtual machine. The KVM hypervisor has also been updated to support the latest industry-standard x86 processors such as Intel Core i3, i5, and i7 CPUs, as well as AMD 15h or Opteron G4 CPUs.
The new release expands its localization enablement with support for English, French, Spanish, simplified Chinese, and Japanese, enabling the platform to be used even more widely around the globe.Without taking anything away from these updates, Red Hat has really moved the needle on RHEV 3.1 with the addition of two other key features that makes the platform more enterprise-ready and brings it closer to feature parity with the virtualization giant, VMware.
The first feature is an updated and hardened ability that allows administrators to make snapshots and clones of running virtual machines. With snapshots, RHEV can save a copy of the running virtual machine for record-keeping purposes. These snapshots can now be created without first having to stop the virtual machine, thus maintaining environment uptime. With cloning, RHEV can now make a copy of a running virtual machine, or it can create a virual machine from a snapshot. This allows users to create copies of the state of a virtual machine at the moment the snapshot was taken. This is particularly valuable in software development environments where frequent testing takes place.
The second feature, live storage migration, may be most important addition in the new release in spite of the fact that it is currently being offered as a tech preview. Live storage migration was a huge feather in VMware's cap when it introduced the technology into vSphere. It quickly became an enterprise checklist item that customers have come to expect in a server virtualization platform.With live storage migration, users can dynamically migrate VM storage across different storage arrays without first shutting down the virtual machine(s) in question. Red Hat notes that its live storage migration will work better once it updates the underlying Red Hat Enterprise Linux (RHEL) platform on which RHEV runs. The full availability of the live storage migration feature will likely appear in a RHEV 3.1.1 update sometime early next year.Red Hat Enterprise Virtualization 3.1 is globally available to subscribing Red Hat customers today.
