Making the Most of Andrew
In AUIS applications, keystroke combinations are another means to get a procedure called for an object. The same procedures are available for keybinding as for menu items. To define a set of keybindings, edit one of the initialization files described previously and add lines like these:
addkey compile-build ^X^E srctextview compile addkey compile-next-error ^X^N srctextview compile addkey compile-previous-error ^X^P srctextview compile addkey fcomp-complete-command-forward \eB typescript fcomp inherit addkey fcomp-complete-filename ^I typescript addkey fcomp-possible-completions \e^I typescript
The first line of the example says that when you are in a srctextview inset (e.g., editing C-source), the procedure name compile-build will be called when you press the keystrokes <control>X followed by <control>E. (The \eB in the fourth line means you should press the escape key and then <shift>b.) You can see a dynamically created list of all the keys that are bound to a procedure by selecting the Describe Bound Keys item on the Misc menu card. You can also query what procedure will be called for any keystroke by selecting the Describe Key item on the Misc menu card.
AUIS is far more than just ez or messages--and yet in many ways it is no more. AUIS is built on a toolkit of objects which combine to provide a set of tools which are consistent in their look and feel and which can be extended or combined with new applications with remarkable ease. In these four articles on AUIS I have not attempted to show any of the underlying toolkit. The Andrew Consortium is dedicated to extending and disseminating this technology. If you think your organization could benefit, I'd encourage you to contact the consortium and talk with us about what else has been done and what's new.
Terry Gliedt (firstname.lastname@example.org) left Big Blue last year after spending over twenty years with IBM. Although he has worked with Un*x and AUIS for over six years, he is a relative newcomer to Linux. Terry does contract programming, teaches classes in C/C++ and Unix and writes the occasional technical document.
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
