I'm writing to express my entire support for what Jason Kroll has written in his article “Musings on Linux Profiteering” published on the Linux Journal web site (http://www.linuxjournal.com/articles/misc/012.html). I've always had the same fears and beliefs, especially because of the love I feel for GNU/Linux, the one and only OS that actually came to me, without asking me for money or anything—on the contrary, offering me great amounts of knowledge I wouldn't have with another OS. The moment I noticed the existence of GNU/Linux, a big change was made in the course of my life. In a country where you have to pay to get proper education, these things mean a lot to all of us—the people who don't have the resources to pay for private education. Not only to us, but to all people who in some way work with computers, providing a way to expand and improve our knowledge.
That's why I fear the monster of money so much, and the harm it could cause the entire GNU/Linux community. And this is why I'm not using FreeBSD, regardless of its good aspects: its license promotes commercial development, allowing anyone to prohibit the use of the software to someone like me, who does not have the resources to pay for software.
Thanks a lot for the article; it could help people realize how much they have to protect.

It was great to see Feathers McGraw featured on your magazine cover. I accidentally discovered Wallace and Gromit while flipping channels a few years ago. PBS was playing two of Nick Park's features; we later purchased a tape of “The Wrong Trousers”. These movies have become favorites of the entire family. The Linux box I set up at work is named Feathers after this character, because he's an outlaw. Hopefully that will soon change.

Kirk Petersen's “Using the Red Hat Package Manager” (January 2000) is a nice article, but has one problem. In the paragraph on “Upgrade Mode”, the example given:
rpm -u penguin-3.26.i386.rpm
will return the following error messages: “error: --u and -uninstall are deprecated and no longer work.” and “Error: Use -e or -erase instead.” At least, it will if you use RPM version 3.0.2 as I do. The command:
rpm -Uvh penguin-3.26.i386.rpmwould work much better. The man page is not very clear, but the info page calls it out correctly.

I noticed that even though the cover page of the Linux Journal had the right date (JANUARY 2000), all the inside pages on the lower right were stamped JANUARY 1900, with an editor's mark changing it to 2000.
Was this intentional or just another Y2K bug? Either way, it bothers me that I didn't notice it until the second reading.

It was intentional. A continuation of our joking claim to be Y2K-compliant on the December cover. The idea was to provide a laugh at all the Y2K uproar and ourselves —Editor
I usually do read my LJ before any dust collects on it, but I'm just now getting my fix with the January issue. In the “thanks, I needed that” kudos department, I really got a huge laugh out of your date. Thanks.

I would like to acknowledge Phil Hughes' article, “Linux Public Trust” (LJ web site, http://www.linuxjournal.com/articles/buzz/027.html). How timely it seems, given the announcement today of the Linux Open Source Expo & Conference Program to be held in Sydney, Australia in March. All the “big names” of the Linux world will be there, with keynote addresses by Robert Bishop of SGI and Robert Young of Red Hat, Inc. Bob Young's credentials include “a career in the computer finance arena, with 20 years of computer industry finance and marketing... which allowed him to see an opportunity with a phenomenon called Linux in 1993.” And here I was, thinking these guys were just hackers in suits!
By the way, the price of a ticket on this gravy train is $1350 AUS. For an extra $125, you can attend the TUXedo Night, featuring none other than John “maddog” Hall. How many other Linux luminaries are attending? Only time will tell. Perhaps one (or more) Linux Journal staff would also like to attend, if only to let the rest of us poorer Linux users know how the other half live. Public Trust? I'll drink to that, but with a virtual beer, at home in front of my computer.
Thanks for what is still an informative and enjoyable magazine, even if the suits appear to be more numerous these days.

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
