Android or WebOS? Try before you buy! Part 2.
This article assumes that you are using:
- VirtualBox 3.0.4 or later.
- An implementation of the Sun Java Runtime Environment. I've chosen to use Sun's version.
- A 32 bit version of Ubuntu Linux (I am using Ubuntu 9.04. Beware-Directions are different for 64 bit versions, as well as Ubuntu 9.10.)
- The Palm Mojo Linux SDK,which consists of two packages:
Steps to download and configure the virtual appliance:
Download and install the Palm Mojo SDK and novacom drivers, as the SDK includes a WebOS virtual image. I used GDebi Package manager to install the two packages. (The Palm developer page suggests that you register an account to download and install the files.)
At the command line, type:
The Palm WebOS emulator should open and boot all by itself.
Feel free to try out the different apps, and the "cards" multitasking OS!
Of course, don't forget to visit linuxjournal.com!
If you're a VirtualBox user, you may notice that the palm-emulator window menus are the same as the menus for VirtualBox virtual appliances. Well, you're right. If you open up Virtualbox on your machine, you'll see that the palm-emulator program has opened up its own virtual appliance, and you can see the info on it in the main VirtualBox window if you're curious about it.
There are a variety of command line options for developing and installing your own apps on the palm virtual appliance, as well.
If you've had any issues with your install, or you are looking for 64 bit instructions, see Palm's official Ubuntu SDK install page.
EDIT: The instructions for Ubuntu 9.10 are slightly different than the directions that are above due to a change in how Ubuntu handles items in the /etc/event.d/ directory. I figured out a fix to allow it to install correctly, and posted it to my blog if you are interested in seeing it.

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
