Android or WebOS? Try before you buy!
This article will help you run two of these (Android and WebOS) as virtual appliances using VirtualBox. In the first part of the article I'll cover Android, in part two (now available), I'll cover WebOS.
In this article, I will be using: Ubuntu 9.04 and VirtualBox (the most recent version is 3.0.8- download it here)
This tip is pretty distro- and OS- independent, though. You could run this appliance on any other distro, or even Windows, if that's the way you butter your bread.
This article piggybacks on the "Put Android Anywhere" article that was featured in the October 2009 issue of Linux Journal, as it mentions running Android in VirtualBox using the "Porting Android to x86" project (http://www.android-x86.org/). I will perform the same task using the Live Android Google Code project. (http://code.google.com/p/live-android/).
Go to the Live Android Google Code Project and download the latest liveCD (0.3 as of this writing. Torrent available here.)
Make a new virtual machine in VirtualBox. Call it "Android" or some other witty name if you are motivated to do so.
Choose the Base Memory Size. VirtualBox defaults to 256MB. Since the HTC Dream (AKA the T-Mobile G1) has only 192 MB Megs of RAM, I figured that this is probably enough.
VirtualBox asks you to select a virtual hard disk. Since we are running Android from a live CD, we don't need one. Uncheck the box to choose a virtual disk, and check "Continue" when the warning box comes up.
Finish creating your virtual appliance, then select "Android" (or whatever your machine name is) from the main VirtualBox window, and click the "Settings" button.
Go to the CD/DVD-ROM section and check "Mount CD/DVD Drive", then select "ISO Image File". Click the folder icon to the right and select the "liveandroidv0.3.iso" file that you just downloaded. Press 'OK".
Click "Start" to start your Android virtual appliance.
Since VirtualBox automatically configures a working Internet connection, feel free to stop by the Linux Journal Website using your shiny new Android Virtual Appliance!
Since it is a live CD, you don't get the resolution of a normal Android phone device, but at least you can kick the tires of the OS. In Part Two we'll look at WebOS.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
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
