GUI Development with Java
The near future for Java shows no letup in the rapid rate of innovation. JFC has just been released, with the 1.2 version of Java. Many promising technologies are just on the horizon, including 3-D, JTAPI, Java Sound, Java Speech and many others. Since there is far too much alphabet soup to remember, please check out the JavaSoft API page at http://java.sun.com/products/api-overview.html. The 3-D API tries to provide a comprehensive imaging model for three-dimensional graphics with some of the best features of PEX, GL and friends. JTAPI lets Java programs control telephony equipment at all scales, from a single voice-mail modem up to a large Private Branch Exchange (PBX). Java Media Framework gives access to all kinds of image, audio and video recording/playback, including Java Sound. Java Sound will provide several sound formats from simply playing sound files (available in 1.2), to recording, to full control over synthesizers such as MIDI. Java Speech will include both speech synthesis and speech recognition.
Many contact tracker systems are available from the simple (my own freeware JabaDex) to the fancy ones limited to MS-Windows, such as Symantec ACT. When Java Sound and JTAPI are released, developers of contact tracker systems can write code to dial the phone, answer it and incorporate voice mail, maybe even add bidirectional FAX support. We will no longer have to write it once for Linux, again for MS-Windows, again for Macintosh and again for Solaris. We will be able, as JavaSoft's slogan promises, to “write once, run anywhere”.
Ian Darwin has used UNIX systems since 1980 (mostly Solaris and OpenBSD in the last few years) and used Java heavily since 1995. He is the author of JabaDex (a 5,000-line Rolodex application entirely in Java), two textbooks (Checking C Programs with Lint, published by O'Reilly, and X User's Guide Volume 3: OPEN LOOK Edition, available on CD-ROM) and more recently, two four-day Java Programming courses through Learning Tree International.

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
