Joel Fernandes submitted a module to export kernel headers through the /proc directory to make it easier for users to extend the kernel without necessarily having the source tree available. He said:

You've deployed Kubernetes, but now how are you going to get it into the hands of your developers and admins securely?

Columnist Dave Taylor reminisces about the early days of UNIX and how Linux evolved and grew from that seed. Twenty five years of Linux Journal. This also marks my 161st column with the magazine too, which means I've been a part of this publication for almost 14 years. Where does the time go?

We asked LJ subscribers to write in and tell us about themselves, so we could feature them in our 25th Anniversary Issue as a way to thank them for their loyalty through the years. The response was so overwhelming, we were able to include only a few of them in the issue, but read on to see all of the responses here and to learn more about your fellow readers. We truly enjoyed "meeting" all of you who participated and are humbled by your words of support.

Follow along with this step-by-step guide to creating your own distribution.

Matthew Wilcox recently realized there might be a value in depending on C extensions provided by the Plan 9 variant of the C programming language. All it would require is using the -fplan9-extensions command-line argument when compiling the kernel. As Matthew pointed out, Plan 9 extensions have been supported in GCC as of version 4.6, which is the minimum version supported by the kernel. So theoretically, there would be no conflict.

How to use ncurses to manipulate your terminal screen.

A review of the elementary distribution and an interview with its founders. In the spring of 2014 (nearly five years ago), I was preparing a regular presentation I give most years—where I look at the bad side (and the good side) of the greater Linux world. As I had done in years prior, I was preparing a graph showing the market share of various Linux distributions changing over time. But, this year, something was different.

I've covered tons of different scientific applications you can run on your computer to do rather complex calculations, but so far, I've not really given much thought to the hardware on which this software runs. So in this article, I take a look at a software package that lets you dive deep down to the level of the logic gates used to build up computational units.

The bash man page is close to 40K words. It's not quite War and Peace, but it could hold its own in a rack of cheap novels. Given the size of bash's documentation, missing a useful feature is easy to do when looking through the man page. For that reason, as well as to look for new features, revisiting the man page occasionally can be a useful thing to do. The sub-section of interest today is Parameter Expansion—that is, $var in its many forms. Don't be confused by the name though, it's really about parameter and variable expansion.
