How Much is Open Source “Worth?” Our New Report.

By Amanda McPherson

Can the principles and practices of Linux be transferred to other industries? We at The Linux Foundation certainly think so and apparently so does the industry. Over the last few years every major technology category has been taken over by open source. Many of those Foundations and projects are being hosted at The Linux Foundation or at other organizations like the Apache Software Foundation and others. Much opinion has been written about the proliferation of open source projects, but not about the value. We set out this year to do a simple code analysis to answer a question: What R&D value are the people who use these projects receiving? Today we’ve released a report that attempts to answer this question, “A $5B Value: Estimating the Total Development Costs in Linux Foundation Collaborative Projects.” We’ve based our findings on a well known code analysis method called COCOMO to analyze all the code in our projects’ code repositories on Git. The results were impressive: As of last month, 115,013,302 total lines of source code were present in Linux Foundation’s Collaborative…

RDO Kilo DVR Deployment (Controller/Network)+Compute+Compute on CentOS 7.1

By Boris Derzhavets Why schema suggested by Benjamin Schmaus for RDO Juno in http://schmaustech.blogspot.com/2014/12/configuring-dvr-in-openstack-juno.html generates several errors on Liberty, which may be tracked down in reasonable time and finally brings to success, just silently fails on RDO Kilo taking away VXLAN tunnels forever. Posting bellow is supposed to address this issue.

The Linux Foundation Releases Value of Collaborative Development Report

By ris The Linux Foundation has announced
the release
of its first ever report that attempts to measure the
estimated value of development costs in its Collaborative Projects. The
report is titled “A $5 Billion Value: Estimating the Total Development Cost
of Linux Foundation’s Collaborative Projects.” “Linux Foundation Collaborative Projects are independently funded software projects that harness the power of collaborative development to fuel innovation across industries and ecosystems. More than 500 companies and thousands of developers from around the world contribute to these open source software projects that are changing the world in which we live.

[$] Compile-time stack validation

By corbet An occasionally heard horror story about the kernel development community
concerns developers who are told that, in order to get their code upstream,
they must first invest considerable effort into fixing a related
subsystem. As with many such stories, this is not an experience many
kernel developers have had, but there is also a
grain of truth behind it. The ongoing live-patching effort, and the extra
work that has been required to push that work forward, is a case in point.
