Letters to the Editor
The URL for downloading the free Linux F compiler from Imagine1, Inc. was left out of my article, Portability and Power with the F Programming Language, published in the October issue of LJ. The correct URL is http://www.imagine1.com/imagine1/.

I'd like to comment on Mr. Hughes' article in the November issue of Linux Journal.
He offered four suggestions that would make Linux a better solution. Two of them were application programs or packages. I agree that creating new applications would be useful, but I'm also concerned with existing Unix freeware that has yet to be ported or compiled on Linux. There is a huge amount of this freeware available but getting it to build on a Linux box is something else again.
What is needed is a software porting project: a central site to collect information about porting specific applications to Linux. Information such as what changes are needed in the makefile, imakefile or prog.tmpl to get the program to compile. Additionally, information about the problems encountered in trying to compile the app would be very useful. This kind of information would help others who are trying to port applications to Linux. So, the site would be a learning resource as well, and this is perhaps most important.
As the knowledge and ability to port software to Linux increases, the number of applications ported will increase at a faster rate. The site wouldn't need to archive binaries or source code, just the specifics about how to compile and the problems encountered. In addition, it would be useful to include information on who's currently working on which application. This would allow communication between groups or individuals working on the same problem and prevent duplication of effort. More applications will make Linux a better solution, and the easiest way to get them is to port existing Unix freeware. A dedicated site would greatly facilitate the endeavor by effectively harnessing the knowledge and ability of the Linux community.

First of all, let me tell you how much I appreciate LJ, for the accuracy of the information it gives and the nice tone it uses.
I write you in reaction to the 1997 Readers' Choice Award that the text editor vi received in the December issue. I'm an old addict of this program, and I still find it fast and useful. But I have always promised myself that I would learn Emacs one of these days, thinking I couldn't remain an old dinosaur using such an old tool. The problem is that I always found Emacs far too complicated. So when I saw the Award, I was genuinely surprised so many people think like me and I had a good laugh.
In short, after reading LJ, I decided that, despite vi being an old and ugly editor, I'll keep using it without any remorse for being an Emacs loser.

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
