Kubernetes is an open source container-orchestration system for automating deployment, scaling, and management of containerized applications. If you've played around with it or OpenShift (which is an enterprise-ready version of Kubernetes in production), the following questions may have occurred to you: Does OpenShift support running applications at scale? What are the cluster limits? How can we tune a cluster to get maximum performance?

When I started my career as an open source attorney, a significant concern was the proliferation of new forms of open source licenses, each requiring time-consuming analysis. As my colleague Scott Peterson points out in his article, "Open source licenses are shared resources": read more

There seems to be a mad rush at the beginning of every year to find ways to be more productive. New Year's resolutions, the itch to start the year off right, and of course, an "out with the old, in with the new" attitude all contribute to this. And the usual round of recommendations is heavily biased towards closed source and proprietary software. It doesn't have to be that way. Here's the first of my picks for 19 new (or new-to-you) open source tools to help you be more productive in 2019. read more

The gzip command is a popular tool used for compressing/decompressing files in Linux. We've already covered the basics of this tool here. This utility produces .gz files in output. But sometimes - like while transferring files - the extension may get chopped off. You'll be glad to know there exists a tool that you can use to force the .gz extension back to these compressed files.

Daniel Colascione submitted some code to support processes knowing when others have terminated. Normally a process can tell when its own child processes have ended, but not unrelated processes, or at least not trivially. Daniel's patch created a new file in the /proc directory entry for each process—a file called "exithand" that is readable by any other process. If the target process is still running, attempts to read() its exithand file will simply block, forcing the querying process to wait. When the target process ends, the read() operation will complete, and the querying process will thereby know that the target process has ended.

Certificates, it turns out, are important.  Expired certificates can cause you huge problems - that's what the stories in the news are telling us. But what is a certificate, why do they expire, and why would that have such a big impact? To answer these questions, let's step back a bit and look at why you need certificates in the first place. read more

News briefs for January 11, 2019.

"Without data, you're just a person with an opinion." Those are the words of W. Edwards Deming, the champion of statistical process control, who was credited as one of the inspirations for what became known as the Japanese post-war economic miracle of 1950 to 1960. Ironically, Japanese manufacturers like Toyota were far more receptive to Deming’s ideas than General Motors and Ford were. read more
