As far as network management is concerned, Nagios is one of the most powerful tools. Nagios can monitor the reachability of remote hosts, as well as the state of services running on them. However, what if we want to monitor something other than network services for a remote host? For example, we may want to […]Continue reading...

I first read about Chris Whittum in an article on Fosters.com. Once I read that he was interested in using open source software in education, I knew I had to learn more about him. After working in education, Chris decided to share his knowledge in an eBook called: Energize Education Through Open Source: Using Open Source Software to Enhance Learning. This resource focuses on how schools can use open source to continue to offer great lessons to students without the high price tag of similar proprietary products.

JR wrote to us to share his open hardware project: pedalSHIELD. It's a great example of open hardware + open source software + open instructions and tutorials. Share your story with Opensource.com. There are a good number of nice programmable DIY guitar pedals out there. So, the pedalSHIELD is nothing new, except for the fact that I think we've strived harder than the rest to keep the project open, simple, supported, and affordable. The idea was to design a platform for Arduino users to learn about digital signal processing, effects, and synthesizers—also to experiment without a deep knowledge in electronics or programming.

OpenStack is an industry-standard open-source cloud management platform. Using OpenStack, one can build public, private or hybrid clouds easily.

Are you new to Arduino? Open hardware like the Arduino Starter Pack from Adafruit is a great way to start tinkering with this small computer board. It is the ideal kit for beginners to open hardware or anyone looking to start a project using the Arduino microcontroller. To start, you need a computer from which you will write the code that will run in the Arduino board. This starter pack comes with an Arduino Uno board, which is likely the simplest. The typical programming cycle is to first write your code on the computer, then upload it to the Arduino board via a standard USB cable. The Arduino softwareis available for Linux, Mac, and Windows.
