Current_Issue.tar.gz - The Bottle Labeled “Drink Me”
Let's face it, the Linux install base is shrinking. No, of course I don't mean numbers, I mean the actual size of the devices onto which Linux is installed. Just like with Alice's trip down the rabbit hole, we're seeing our favorite OS embedded on smaller and smaller hardware. This month, we talk about some of those places and teach you how to make a “Drink Me” bottle for your own projects.
If installing Linux on something as mundane as a phone isn't your cup of tea, you'll likely be interested in Anton Borisov's article on the Linux-powered spider robot, hexapod. A device right out of a science-fiction movie, and also my nightmares, the spider bot is powered by Linux. Anton interviews its creator, Matt Bunting, and explains how it works. Tom Parkin talks about bugs this month too, although his article is a little less creepy. Tom shows how to de-bug embedded Linux platforms with GDB and Python. If you're a Linux developer, chances are you're familiar with GDB. Tom demonstrates version 7, which now has Python support.
When it comes to embedded Linux projects, they don't get much smaller than with the Gumstix. James McColl walks us through compiling a custom kernel for the Gumstix Overo Fire. If you want to install Linux on a device you could disguise as a stick of chewing gum, or if you're just interested in learning to compile custom embedded kernels, be sure to check it out.
What could be scarier than the robotic spider, hexapod? Well, perhaps if that same spider bot were able to speak to us. Rick Rogers explores speech recognition and synthesis for embedded systems. Although the technology certainly isn't limited to autonomous spider robots, I fear our readers might try to do just that. If you do, please don't send me one for review.
We've got other Linux distributions designed for embedded systems this month, one of which is CyanogenMod 7.0. I had the opportunity to interview Steve Kondik from the CyanogenMod team, and I show off some of the new features of this cutting-edge Android ROM. Tiny installs of Linux certainly aren't a new idea, and Joey Bernard shows us a tiny distribution designed for computers. Even cell-phone developers would have a hard time beating the space saved by Tiny Core Linux. At 10MB, it has a full graphical environment and can run completely in RAM.
Perhaps the idea of a premade distribution leaves a sour taste in your mouth. That's fine too. Alexander Sirotkin shows how to roll your own embedded Linux system with Buildroot. This is useful for times when an existing distribution doesn't suit your needs—for example, if you were building a sentient robotic spider that could talk and understand the spoken word. You'd most likely want to build a custom embedded Linux environment, so you could include the WORLD_DOMINATION.c module and, my favorite, the STAY_AWAY_FROM_SHAWN.c module. The latter is available to any robotic spider programmers free of charge.
This month isn't all about embedded Linux, however. Whether you learn about using the OAuth protocol from my friend Adrian Hannah or want to figure out days of the week in a script with Dave Taylor, this issue has you covered. We've also got our regular lineup of new product announcements, UpFront tidbits and enough geeky tips and tricks to keep any Linux lover happy. And remember, if this embedded issue is making you feel a bit too small, we'll try to save you some of that cake with the “Eat Me” sign next to it. It worked for Alice!

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
