A Look at the Filesystem Hierarchy Standard 3.0

Filed under
Linux

It was big news when the 3.0 kernel was released at the end of July, but as luck would have it, another fundamental piece of your average distribution is about to bump its own version number up to 3.0 as well: the filesystem hierarchy standard (FHS). If you're not sure exactly what that means or why you should care, don't worry. It's the distros that implement the FHS — when it goes well, all you know is that your system runs smoothly. But that doesn't mean there's nothing important hidden away in this new release.

The What Now?

The FHS defines the basic structure of a Unix-like operating system — what the directories are, what types of files and data belong in each, and so on. This is important for application developers (so that they know to create temporary files in /tmp/ rather than in the user's home directory, for instance), but it is also important for system administrators. Not only does FHS specify where the directories go, but it specifies important properties like which directories must be mounted read-only (critical for security) and which must be available at boot time (so that vital directories are on local disks not NFS mounts that won't be available early in the boot sequence).

NASA Space App Challenger Runs Yocto on an Intel Edison-Based Nanosat

NASA has long had an interest in Linux and other open source technologies, and has used Linux in a variety of systems, including the R2 humanoid robot now at work at the International Space Station. With its International NASA Space App Challenge, the space agency is tapping into the maker gestalt to come up with new ideas, as well as inspire future space engineers. In this year's two-day Space App Challenge hackathon, which ran April 10-11 in 133 cities around the world, NASA greeted participants with over 25 challenges split into Earth, Outer Space, Humans, and Robotics categories.

How to Find the Best Open Source Project to Work On

In my last article for Linux.com, I explored a few ways newcomers to open source projects can get started. While there are many resources to explore open source project communities, choosing which project to contribute to can still be a quite daunting task. You could go searching in the more than 23 million repositories on GitHub, the world’s largest source code hosting platform. But there are better ways. This article is meant to be a short guide to help novice open source practitioners more easily identify the first project they’d like to contribute to. Read more

Linux 4.1 Kernel Benchmarks With An Intel Core i7 IVB System

Yesterday I ran some fresh tests of Intel Ivy Bridge on the latest Mesa Git code to see if the performance has changed much recently for the slightly-older generation of Intel HD Graphics. Today I've done some similar tests in kernel-space with the Linux 4.1 kernel. I ran benchmarks from the same Core i7 3770K system while testing the vanilla Linux 3.19, 4.0, and 4.1 Git kernels and running various graphics tests to see if there's been any recent i915 DRM kernel changes affecting the Ivy Bridge graphics performance.
