In The Penguin Post (yes, it exists, www.penguin-place.com) we recently found two reports of great interest and no importance suggesting that penguins are unusually sporting birds.
Item #1: Bird Bowling: The British Air Force in the Falkland Islands discovered a way to “bowl” for penguins by flying over large groups of the groundbound birds. See, penguins are observant creatures that are unusually interested in airplanes (flight envy perhaps?). Herds of up to ten thousand penguins will, in unison, all point their beaks at a plane flying overhead, tracking it accurately as it passes by. Sooo...if the pilots fly over the penguins at just the right angle, the little animals all fall over backwards—again in unison—just as the plane passes overhead.
Item #2: Birdball: The penguins hanging around the Woods Hole Oceanographic Institution in Antarctica have been observed to take interest in games of football played by humans on flat fields of snow and ice.
One day the scientists came out to discover that the penguins had taken the field. They would line up in two rough groups, and then start squawking and running around bumping into each other. After a bit of this, they would pick themselves up and start the process all over again. They hadn't quite got the idea that a ball was important to the process, but they kept at it for some time. The sight was so ridiculous that everyone was rolling on the ice laughing.
Borland, the development tools company that recently returned to its original name (shedding the confusing “Inprise”), has finally come out with Kylix, its long-awaited rapid application development (RAD) Integrated Development Environment (IDE) for Linux—and for cross-platform development as well.
Developed entirely for Linux as a native Linux development toolset, Kylix is also very familiar to users of Delphi, Borland's popular Windows RAD toolset. Kylix not only allows developers to use nearly identical tools and skills but to move Delphi-developed Windows applications over to Linux. Borland claims there are over two million Delphi and C++ Builder users, millions of applications, thousands of vertical and horizontal components, and over five hundred registered third-party tool and component vendors that will easily leverage from the Windows world to Linux using Kylix.
At the core of Kylix is the Component Library for Cross Platform Development, or CLX, pronounced “clicks”. This is an open-source application infrastructure that supports both the commercial version of Kylix and the core component architecture, which Borland is releasing under the General Public License (GPL). These are expressed in three product editions: Open Edition, Desktop Developer and Server Developer. All three are available as shrink-wrapped products with the Open Edition available for free download as well. All CLX class libraries, however, are open source and GPL'd.
Like other commercial Linux vendors, Borland is attempting to support both commercial application development and ubiquitous Linux-based infrastructure. There is plenty of demand for both. This was manifest before the Kylix project began, when Borland conducted an extensive survey (partly through Linux Journal) in 1999. The survey had more than 24,000 responses that included both Linux and Windows developers. RAD development tools were at the top of the wish list for both groups. The top types of planned applications were application/utility development and client/server database development.
Ted Shelton characterizes Kylix's potential impact this way:
Imagine what would happen if Microsoft open sourced .Net, the crown jewels of their new strategy to dominate the emerging market for “web services”. Imagine how thousands of developers would be able to take .Net and not just build applications with it, but truly extend it—move it to new operating systems, add functionality, specialize key interfaces for new devices, environments and vertical applications. Imagine how fast the world would change. We're ready to provide the drills, hammers and circular saws for developers to build an entirely new application infrastructure, one that will be industrial strength, open source and Linux-ready.
After the press conference announcing Kylix, it appeared to me that the deepest significance of Kylix may be in its cross-platform class libraries—in CLX. During the conference, Borland CEO and President Dale Fuller compared CLX to .Net, calling CLX “.Now”. I asked Ted Shelton if this positioned CLX as a cross-platform framework that competed not only with .Net (which is not really cross-platform but cross-language within the Windows platform), but with Java as well. He replied, “When you develop, you essentially choose a set of class libraries. Java offers one. Microsoft offers another with .Net. CLX is now the third. But it's the only one that is both open source and cross platform. I expect that after the Open Source community gets into it, the CLX libraries will outnumber Java's.”
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
