Nowadays Linux runs on almost anything. You can get a cheap PC and turn it into a media station or web server or whatever else you wish at no aditional cost. Hardware is cheap also. With the advent of the Raspberry Pi and similar small computer boards one can get a fully-functional PC for the price you'd usually pay for a sixpack of beer. In this LinuxConfig series we'll not only build a Linux computer; we'll build an entire Linux cluster with four nodes and learn how to manage it so that all the nodes respond at the same time to the same commands.

About a year ago, I wrote about measuring air quality using a Raspberry Pi and a cheap sensor. We've been using this project in our school and privately for a few years now. However, it has one disadvantage: It is not portable because it depends on a WLAN network or a wired network connection to work. You can't even access the sensor's measurements if the Raspberry Pi and the smartphone or computer are not on the same network.

In this week's edition of our open source news roundup, we take a look at a 3D-print system for optical cardiography, Carnegie Mellon's Digital Learning Tools, Apache Software Foundation's 20th anniversary, and more.

I spend a lot of time doing research for my books and Opensource.com articles. Sometimes this leads me to discover bugs in the software I use, including Fedora and the Linux kernel. As a long-time Linux user and sysadmin, I have benefited greatly from GNU/Linux, and I like to give back. I am not a C language programmer, so I don't create fixes and submit them with bug reports, as some people do. But a way I can return some value to the Linux community is by reporting bugs. read more
