Backport upstream commits to stable RDO Mitaka release && Deployments with Keystone API V3

Posting bellow is written  with intend to avoid waiting until “koji” build will appear in updates repo of stable RDO Mitaka release, what might take a couple of months or so. Actually, it doesn’t require knowledge how to write properly source RH’s rpm file. It just needs picking up raw content of git commits from upstream git repo converting them into patches and rebuild required src.rpm(s) with patch(es) needed. There is also not commonly known command `rpm -qf` which is very useful when you need to detect which rpm has installed particular file. Just to know which src.rpm should be downloaded for git commit referencing
say “cinder.rb”

Tigera Plans to Solve the Container Networking Challenge

Container networking is a messy affair. Tigera, a startup announced earlier this month by Metaswitch veterans, aims to make it simpler and more secure by melding Project Calico and CoreOS flannel into a new open source platform called Canal.

Although containers from CoreOS, Docker, and other vendors reached the adoption phase some time ago, solutions for networking containers together remain immature, according to Wikibon senior analyst Stu Miniman. “We are very early in how networking is going to be solved in the container world,” he says.

There are already several contenders in this area. One is libnetwork, a container networking platform built by Docker.Weave Net from Weaveworks, which offers an integrated management solution for Docker containers, is another. And there is flannel, a CoreOS network fabric that relies on etcd to store configuration data.

Driving Cars Into The Future with Linux

I don’t think much about it while I’m driving, but I sure do love that my car is equipped with a system that lets me use a few buttons and my voice to call my wife, mom, and children. That same system allows me to choose whether I listen to music streaming from the cloud, satellite radio, or the more traditional AM/FM radio. I also get weather updates and can direct my in-vehicle GPS to find the fastest route to my next destination….

In a recent news roundup, Scott Nesbitt cited an article that said Ford Motor Company is getting substantial backing from a rival automaker for its open sourceSmart Device Link (SDL) middleware framework, which supports mobile phones. SDL is a project of the GENIVI Alliance, a nonprofit committed to building middleware to support open source in-vehicle infotainment systems.

https://www.youtube.com/watch?v=hTfIAWhd3qI?list=PLGeM09tlguZQ3ouijqG4r1YIIZYxCKsLp

Netflix is the world’s leading internet television network. That didn’t happen by accident or simple fortune – we are data-driven as part of our culture, and have built the tools needed to navigate the unchartered waters of delivering internet video at scale and becoming the first truly global storyteller in movies and television.

Brian Sullivan is the Director of the Streaming Data Science and Engineering team at Netflix, the world’s leading Internet television network. His team builds analytic systems and delivers insight into the streaming activity across hundreds of client devices, world-class server systems and content delivery networks to serve up a third of peak internet traffic in North America. Brian’s prior experience spans the analytic stack from software engineering, data architecture, reporting/visualization and analysis. He has also worked across a number of domains including virtual worlds, banking, retail, automobile traffic measurement and fingerprint recognition systems.

7 Best Command Line Navigation Tools

The cd command is a command-line OS shell command used to change the current working directory. A directory is a logical section of a file system used to hold files. Directories may also contain other directories. The cd command can be used to change into a subdirectory, move back into the parent directory, move all the way back to the root directory or move to any given directory.

The purpose of this article is to identify some tiny but useful tools that complement the cd command. They help users to navigate faster around the filesystem, and increase productivity when using the shell.

ODPi and ASF: Building a Stronger Hadoop Ecosystem – John Mertic

https://www.youtube.com/watch?v=XUl7vlVwNaI?list=PLGeM09tlguZQ3ouijqG4r1YIIZYxCKsLp

ODPi Director of Program Management, John Mertic, explains how the work of the ODPi complements and supports that of the ASF. Since ODPi’s launch in 2015, there has been some confusion around how its work may overlap, or potentially compete, with that of the ASF. Mertic will detail how the ODPi’s specifications and by-laws reinforce the role of the ASF as the singular place where Hadoop development occurs. He will also explain how the ODPi’s focus on the downstream Hadoop ecosystem oxygenates the Big Data market and stimulates growth.

It Takes a Village: Making Data Projects Work – Amy Gaskins, Big Data Project Director

https://www.youtube.com/watch?v=3DAXs4x6EW4?list=PLGeM09tlguZQ3ouijqG4r1YIIZYxCKsLp

We’ve all seen an innovative data project that fails and all too often the reason isn’t a lack of technical skill among the team members. In order to succeed in complex organizations, data project teams require both diversity and versatility (and their sources aren’t always where you might expect). From the battlefield to the boardroom, Amy Gaskin’s experience demonstrates that incongruous teams can achieve remarkable results.

Amy Gaskins has previously worked for NOAA and MetLife. Amy was an Assistant Vice President in MetLife’s Global Technology & Operations, managing data science projects in Europe, the Middle East, and North Africa. In her previous government service, Amy spent over 10 years as a senior intelligence analyst supporting various agencies within the United States Intelligence Community and Department of Defense.
