June 2013 Issue of Linux Journal: Android
The Face of a Toaster
Science-fiction geeks have very specific definitions for their (okay, "our") jargon. A cyborg is a hybrid mechanical and organic creature. An AI (artificial intelligence) is a purely electronic device or program capable of thought. And an android is a purely mechanical and electronic device with a human appearance. In Star Trek terms, the Borg are cyborgs, and Data is an android. Then Google came and messed everything up. "Android" is now synonymous with the operating system on phones and tablets everywhere. Unless it's an obscure social commentary on square shapes and human obesity, I think it's safe to assume Google just went with a cool-sounding, futuristic name. This month, we focus on Google's Android, the Linux-based operating system that's taking over the planet.
Reuven M. Lerner starts out the issue with the universal translator of the programming world—namely, Unicode. Although it makes life easier all across the planet, working with Unicode can be challenging. Reuven addresses some of those challenges, and shows how to work through them. Dave Taylor helps us work through some things too as he continues his series on the Cribbage script we've been working on. Whether you want to learn scripting, or better understand Cribbage, it's an awesome series.
Kyle Rankin brings us another Raspberry Pi article this month, this time doing fault tolerance with redundant Web servers. Kyle's articles always make me hungry for knowledge, but the past couple months, his titles have made me hungry in general—Raspberry Pi, indeed. I, on the other hand, talk about cryptocurrency this month. It's been a while since I've mentioned Bitcoins or Litecoins, and with the recent bubble, perhaps it's time to dust off those miners and start generating cash. It's not a surefire way to get rich, but you might be able to earn enough income to buy some Raspberry Pi devices and keep up with Kyle!
Generally, developers develop computer programs on computers. They also develop mobile applications on computers. Joey Bernard shows us AIDE this month, which is a nifty way to develop Android apps while using the Android OS! If you've ever wanted to do some coding while on the road, but you're stuck with only your tablet, you'll want to check out this article. Nitish Tiwari delves into development this month as well, but he discusses testing side of things. If you want to port your application to new hardware, go directly to his article and start reading.
Bill Childers and I are kindred spirits when it comes to mobile technology. I think his pile of goodies is a little taller than mine, but thankfully, he shares his experiences with us all. A couple months back, I wrote about my Nexus 7 tablet. Bill goes in a slightly different direction with his Nexus 7, and he explains how to boot in to completely different ROMs! Whether you want to try CyanogenMod or Ubuntu on your tablet, MultiBOOT is your tool, and Bill describes how to use it.
At times, we can get arrogant about security as Linux users. Himanshu Arora looks deeper into viruses and worms. Are we safer by design? Are we setting ourselves up for disaster? Himanshu's article is a must-read for anyone interested in the debate. And finally, Tracy Ragan's opinion piece on DevOps is one that hits home to an old-timer like me. The scale of data centers is such that the traditional static scripts and hacks are being phased out by newer, truly automated systems.
If you think Android is a little green robot that lives in your phone, or if you think Google has blasphemed all of science fiction, this Android issue of Linux Journal should be enjoyable. I can't bring myself to make a cheesy comment like, "set phasers to awesome", so I'll just hope you enjoy this issue. We think it's awesome, phasers or no.

Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
