Counting the Cost of Free: What Value, Linux?
Lora Bentley spoke with Amanda McPherson, marketing and developer programs VP at the Linux Foundation. She and two colleagues recently released a new paper, “Estimating the Total Development Cost of a Linux Distribution.”
Bentley: Your study found that it would cost $1.4 billion for a company to build the Linux kernel from scratch today, and $10.8 billion to build an entire Linux distribution similar to Fedora 9. Can you explain how you reached those figures?
McPherson: The conclusions were reached by using David Wheeler’s well-known SLOC tool, SLOCCount, which makes use of the industry standard COnstructive COst MOdel (COCOMO). This methodology takes into account lines of code written, the appropriate number of labor years, and salary adjustments for inflation. We wanted to come up with a real number based on the one thing you can quantify in open source — code. We used a well-regarded methodology and tool that had been used before. Instead of making random projects, we thought this was the best way to approach it.
Bentley: Why the Fedora community distribution and not another?

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
