beautiful-manjaro-deepin-16-03 Manjaro Deepin, one of the latest additions to the Manjaro family, has been upgraded to version 16.03 and is now ready for download.

Manjaro Linux distribution is based on Arch Linux, and the project has a build for pretty much all of the desktop environments and window managers out there. The Deepin flavor is just the latest one and it also happens to be one of the most interesting. Deepin Linux took everyone by surprise with their new and revolutionary desktop environment, and the Manjaro community couldn’t pass the opportunity of adopting the new solution for their distro.

Tech Firms Grapple With How to Make Open Source Pay

Issue gains currency, as private investors pour money into open-source startups. …Open-source projects underpin services offered by companies such Facebook Inc., Twitter Inc., and Uber Technologies Inc, and open-source-based operating systems such as Linux power many corporate servers, financial trading platforms, and Android phones. However, companies that offer such software as their primary product by and large have found it rough going.

Since most open-source firms donâ€™t have a product to sell, they historically made money by selling technical servicesâ€”essentially tech support and consulting servicesâ€”that help companies take advantage of free tools.

Truly Random Number Generator Promises Stronger Encryption Across All Devices, Cloud

So long pseudo-random number generator. Quantum mechanics brought us true randomness to power our crypto algorithms, and it’s strengthening encryption in the cloud, datacenter, and the Internet of Things.

In light of yet another SSL vulnerability this week, any improvements to the underpinnings of encryption would be welcome. One weakness of encryption algorithms — one that simply increasing from 128-bit to 256-bit can’t solve — is that they are based onpseudo-random number generators; not truly random number generators. Whitewood Encryption Systems, which launched in summer 2015, is changing that, by using quantum mechanics.

They generate truly random numbers by harnessing the entropy (randomness or disorder) of nature, which is much more random than any of the sources computing systems currently glean for entropy.

Mozilla-Iot-AM Mozilla announced four Firefox OS to Connected Devices projects, including a home automation system, an AI agent, a voice interface, and a â€œSensorWeb.â€

In December, when Mozilla announced a halt to development and sales of its open source, Linux-based Firefox OS mobile distribution, the company said it was already shifting the HTML5-focused open source Linux OS to Internet of Things projects. A month ago, Ari Jaaksi, Mozillaâ€™s SVP of Connected Devices posted a blog entry noting progress on projects such as its Vaani voice interface. Jaaksi has now revealed more details on Vaani and three other projects, and invited open source developers to pitch in.

HPC Finally Climbing to the Cloud

Although commerce and consumers have been computing in the cloud for years, the high-performance computing sector has been more hesitant. But all that may now be changing.

The cost of cloud computing for HPC is falling, while new programming models that will allow HPC workloads to run more efficiently in the cloud are becoming available. “Public cloud” providers are installing hardware configurations that are more suited to HPC, while private clouds are giving users experience of how to run their jobs in a cloud environment.

…Van Leeuwen makes a useful distinction that clarifies the different types of cloud technologies currently being used, by pointing to the difference between ‘cloud bursting’ and running HPC workloads on OpenStack in data centers. The difference is, he explained, that: “the original cloud-bursting scenario is about adding more capacity in a flexible way; whereas, if you have 100 servers in your data centre, by adding OpenStack to it you don’t get a single extra CPU cycle, you’re just redistributing it in a more effective, more efficient manner.”

The latest version of the stable Linux kernel, 4.4.4, has been revealed today by Greg Kroah-Hartman, which makes it the most advanced stable version available. Even if the official website of the Linux kernel hasn’t been updated with this information, the Linux kernel 4.4 branch is an LTS one.

“I’m announcing the release of the 4.4.4 kernel. All users of the 4.4 kernel series must upgrade. The updated 4.4.y git tree can be found at git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.4.y and can be browsed at the normal kernel.org git web browser: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary,” said Greg Kroah-Hartman in his regular mailing list update.

P1090270-1 Samsung has announced that it is now shipping its PM1633a SSD. That’s a boringly mundane name for a drive that’s anything but: the PM1633a isn’t just the biggest SSD around, it’s straight-up the biggest drive around. At 15.36TB, it dwarfs other SSDs and surpasses the capacity even of the very latest magnetic spinning disks. Remarkably, it packs all this storage into a conventional 2.5-inch package.

Industry experts discussed the risks, benefits and next steps around data in the government space during the 2016 RSA Conference…

As one of the largest collectors of personal data, government is in the unique position to both use and lose valuable constituent information. An expert panel took to the issue to at the 2016 RSA Conference, discussing the risks and necessary next steps in this space.

Because of the ever-changing nature of data collection, data use and privacy concerns, J.R. Reagan, global chief information security officer with Deloitte, said there is simply no easy way to flip-flop between acceptable and unacceptable data uses when presented with the aggregate nature of huge amounts of digital information.

Here’s a look at four primary issues of data in the digital age.

Setup DVR on RDO Liberty Controller && 2(x)Computes ML2/OVS/VLAN landscape

Just a reminder in Juno and Kilo DVR was available for deployments using VXLAN tunneling and required l2population activation on all nodes. One of new features of Liberty is DVR compatibility with ML2&OVS&VLAN deployed landscapes. On RDO Liberty packstack doesn’t play so nicely doing VLAN deployment as in case of VXLAN tunneling. Attempt to use old templates for answer file just does all configs properly only on Controller/Network Node. However, it is not a problem replicate across Compute Nodes landscape required samples ifcfg-br-eth1,ifcfg-eth1 ( supporting VLAN vm/data network ) and openvswitch_agent.ini , what makes RDO Liberty system attractive not only in case VXLAN (GRE) tunneling deployments, but still pretty comfortable for VLAN setups.
I also have to notice that on RDO Kilo same answer-file does Compute Nodes automatically and properly .
DVR setup on VLAN landscape is just easier then in case with VXLAN tunneling , l2population bringing up is not required
