The relational database company’s upcoming MariaDB ColumnStore is a columnar storage engine for massively parallel distributed query execution and data loading, supporting use cases ranging from real-time to batch to algorithmic.

MariaDB on Tuesday moved to unite transactional and analytical processing in a single relational database with the announcement of the upcoming release of MariaDB ColumnStore. “We’re uniting transactional and big data analytics all together under one roof,” says Michael Howard, CEO of MariaDB. “It’s the same MariaDB interface, security, SQL richness simplifying management. You don’t need to buy specialized hardware. It’s one unified platform.”

Google Reveals its Shift to an Open Security Architecture

Perimeter fences down, security posture up – Google shows how it’s done. Google has revealed how it completely changed its security architecture, shifting from a traditional infrastructure to a more open model in which all network traffic is treated with suspicion.

The project, called BeyondCorp, shifted the company from a perimeter security model to one where access to services and tools are not gated according to a user’s physical location or their originating network, but instead deploys access policies based on information about a device, its state and associated user.

The architecture was disclosed in a detailed article published on Usenix. “BeyondCorp considers both internal networks and external networks to be completely untrusted, and gates access to applications by dynamically asserting and enforcing levels, or ‘tiers’, of access,” claim the Google engineers behind BeyondCorp.

libreoffice-5-1-2-officially-released-wi We have just been informed by Italo Vignoli of The Document Foundation about the availability of second maintenance release of the LibreOffice 5.1 open-source office suite.

LibreOffice 5.1.2 is the second point release in the current stable and most advanced version of the office suite preinstalled in numerous GNU/Linux operating systems by default, and it comes approximately one month after the release of the first maintenance build to fix many of the bugs reported by users.
“LibreOffice 5.1.2 is targeted at technology enthusiasts, early adopters and power users. For more conservative users, and for enterprise deployments, TDF suggests the “still” version: LibreOffice 5.0.5. …”

Linux-targeting malware family is a “high” risk, warn security researchers.

Hackers are using malware which targets Linux to build botnets to launch distributed denial of service (DDoS attacks) security researchers have warned.

The so-called BillGates Trojan botnet family of malware – apparently so named by the virus writers because it targets machines running Linux, not Windows – has been labelled with a “high” risk factor in a threat advisory issued by Akamai’s Security Intelligence Research Team.

Which technology will you use to deploy your next big application?

The data center is changing. Again. In the olden days, really not all that many years ago, pretty much every server that sat on a rack in a data center was fairly straightforward (if you could call it that). Each machine ran a single operating system, and often many programs, each requiring their own updates, upgrades, and patches. It was, putting it nicely, a hard situation to maintain, though many management tools emerged to help administrators keep all of their machines safe, secure, and up-to-date.

The Linux Foundation Partners with Kids on Computers to Support the Next Generation of Open Source Professionals

At The Linux Foundation we support a variety of community initiatives and organizations that are advancing free and open source software and creating opportunities for people from all backgrounds and ages to contribute. We focus this support through partnerships, donations and activities like the workshop we’re planning with Kids on Computers.

Just last week we announced a comprehensive, new partnership with Kids on Computers in an effort to further our commitment to supporting the future of open source. Our partnership includes a hands-on workshop for children to run their first Linux installation and will likely be hosted at a LinuxCon event this year. It also includes free and discounted passes to Linux Foundation events for members and volunteers of Kids on Computers. We are also making a donation to the organization to help advance their larger education and technology accessibility mission.

Kids on Computers is a nonprofit organization that establishes computer labs around the world for kids who don’t have access to technology. The organization uses free and open source software (FOSS) to build and supply computers to eighteen computer labs throughout Mexico, India, Morocco, Nepal and Argentina.Their work extends opportunities to the next-generation of FOSS developers and SysAdmins.

“Linux provides a free and open source platform for our kids to learn about technology,” said Avni Khatri, Kids on Computers President. “This partnership with The Linux Foundation aligns with our mission perfectly and will allow us to impact the lives of even more kids. Partnerships like this are what keep the technology field growing and moving in new directions. We thank The Linux Foundation for helping to bring technology to underprivileged kids!”

Through our community giving work we hope to help advance like-minded organizations that protect and advance free and open source software; increase diversity in technology and the open source community; support career development opportunities for the next generation of IT managers and developers, regardless of background or circumstances; and empower open source professionals to take on leadership opportunities and advance open source. The greatest shared technology investments begin with a vision, a passion for innovation, and a talent pool of individuals who understand the power of collaboration. We’re excited about our work with Kids on Computers and for what the future holds.

Neutron work flow for Docker Hypervisor running on DVR Cluster RDO Mitaka && HA support for Glance storage using to load nova-docker instances

Refreshing in memory similar problem with Nova-Docker Driver (Kilo) with which I had same kind of problems (VXLAN connection Controller <==> Compute) on F22 (OVS 2.4.0) when the same driver worked fine on CentOS 7.1 (OVS 2.3.1). I just guess that Nova-Docker driver has a problem with OVS 2.4.0 no matter of stable/kilo, stable/liberty, stable/mitaka branches been checked out for driver build.

I have to notice that issue is related specifically with ML2&OVS&VXLAN setup, RDO Mitaka deployment ML2&OVS&VLAN works with Nova-Docker (stable/mitaka) with no problems.

I have not run ovs-ofctl dump-flows at br-tun bridges and etc,because even having proved malfunctinality I cannot file it to BZ.Nova-Docker Driver is not packaged for RDO so it’s upstream stuff.Upstream won’t consider issue which involves build driver from source on RDO Mitaka (RC1).

Thus as quick and efficient workaround I suggest DVR deployment setup.It will result South-North traffic to be forwarded right away from host running Docker Hypervisor to Internet and vice/versa due to basic “fg” functionality ( outgoing interface of fip-namespace,residing on Compute node having L3 agent running in “dvr” agent_mode ).
