The Collaborative Virtual Workspace
As I mentioned earlier, a Java source client also exists for CVW. This client uses the Java 2 port recently released by the Blackdown organization (http://www.blackdown.org/). Although this client does provide some newer and more advanced features and also works on Linux, it can be considered a beta-release and requires some bug fixes. We do believe, however, this client will eventually become the standard CVW client. We hope that many users will find it interesting and build it up to match the capabilities of the Tcl/Tk client.
Some investigation into replacing the document server has begun. Although the current server performs sufficiently, it has several drawbacks: the interactions between the client and server can't be made secure, the repository consists of one large directory, and no real authentication mechanisms exist. We hope to address these issues with a new document server that provides greater capabilities and performance.
Since CVW has been made into an open-source project, MITRE will be concentrating more on developing a next-generation collaboration system. We hope many people will find CVW as useful to them as it has been to us and continue to improve on it. Since it is a relative newborn as an Internet project, many development possibilities exist. We hope CVW will continue to expose many people to the possibilities of computer collaboration.
Stephen Jones currently works as a software engineer for The MITRE Corporation. When he's not out on his Harley, he enjoys hanging out with his wife Lynn, two-year-old computer-fiend son Bradley, and new arrival, son Derek. He can be reached via e-mail at firstname.lastname@example.org.
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
