This tutorial provides a general description of updating Linux-based firmware and illustrates it with some specific implementations. First, consider the sections of the memory system (Figure 1) and parts of memory that should be updated while transferring software to a new version. more>>

Your First Bite of Raspberry Pi

By Shawn Powers 

I have to give Kyle Rankin all the credit for my Raspberry Pi collection. I never really felt geeky enough to do anything with an Arduino, and for some reason I mentally lumped the RPi into the same world. Boy was I short-sighted! Thankfully Kyle showed me the light, and I managed to snag some of the new 512MB model B units. more>>

Arduino Teaches Old Coder New Tricks

By Edward Comer 

I became aware of the Arduino Project from occasional media reports and a presentation at Atlanta LinuxFest 2009. I was impressed with what the Arduino community was doing, but at that time, I saw no personal use for it. It took a grandson who is heavily involved in a high-school competitive robotics program to change things for me. more>>

ZaTab: ZaReason's Open Tablet

By Kevin Bush 

Quite a few options exist as far as Android tablets go. Some of them are great choices for personal entertainment and media consumption. Google's new Nexus 7 is a powerful little beast designed to serve up media from Google Play. Amazon's Kindle Fire is a great device for tapping Amazon's extensive content offerings. more>>

Learning to Program the Arduino

By Amit Saha 

This article should acquaint you with basic Arduino programming and show you how to write programs that interact with objects in the real world. (A mandatory disclaimer: the last time I really studied electronics was way back in high school, so this article focuses more on the programming aspects, rather than the electronic side of things.) more>>

Summer Hacking

By Johan Thelin 

It is summer on the northern hemisphere, and I've decided to target a smaller system than I've been used to in the last couple of years. In particular, I've decided to finally open my dear old PICkit II. The goal is to be able to work with this board from within a Linux environment. more>>

Booting Bare Hardware

By Johan Thelin 

Booting a computer is always more complex than one wants to think. On the PC side, it looks as if BIOS finally is retired and replaced by EFI (I wonder which was the last OS to use BIOS for anything that just loading a secondary bootloader). On Mac, EFI has been around for a while. On embedded Linux systems, however, u-boot has been a big player for a long time. more>>

Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
