December 2005, From the Publisher: The Desktops Are Coming
I know we are all going to miss Don Marti. Many of us LJ folks have known Don “forever”, and we have worked with him for five years. Don had the big picture, knew his bits and was a great writer—exactly the right mix.
Getting to write this piece gives me a chance to talk a bit about what is changing in Linux and, because of that, what I have been working on.
We as a company decided to switch everyone in the office over to KDE, back on version 1. Everyone thought I was crazy, and many times, I believed them. However, this meant they all knew what Linux was and used it every day. Since then, while most people were watching Linux (and Apache) take over the server market, the desktop quietly matured. It isn't perfect today, but it is certainly easy for your grandmother to sit down at a Linux box and use it. But LJ's job isn't done. Desktops still require new drivers, new applications, security and, in general, administration. LJ here to help you with that, and will be for years, but Linux has a growing user market—users like the receptionist I subjected to KDE 1 so many years ago.
More than a year ago, we started working on a new magazine named TUX, and it's different in a lot of ways—not just in audience: 1) it is distributed as a PDF; 2) it tells you how to get things done rather than what is inside; 3) it's free; and 4) all the back issues are available for free too.
Is there a catch? Yes. We want lots more people to use Linux. Some of them will become geeks and, thus, LJ readers. But, lots of them will simply get to see why we are so excited about what we do and, hopefully, buy a few Linux systems. Some of those people will buy a system for home, but many will end up using Linux at work. That gets us all closer to the goal—World Domination. If you have a friend or relative who just wants to use a computer and you think Linux is the right answer, point them at TUX (www.tuxmagazine.com) for articles and free subscription links. And, maybe if you are pretty geeky and know how to do everything on the command line, you should get a subscription too. Although I am writing this with vi, some GUI programs out there are useful—from amaroK to Inkscape.
Enough about what else we are up to. Let's talk about what we did this month in LJ.
Reuven continues looking at pieces of Ruby on Rails, focusing on ActiveRecord, the object-relational mapper (page 14). I have been working on a project using Ruby recently, although we rejected using Rails because the project was far from a pure Web application. Ruby on Rails certainly has its place, and Reuven is doing a great job of showing us how to use it.
Marcel looks into amaroK and new features that have recently appeared in this fancy music player (page 22). Even though OGG isn't French for anything, Marcel fills you in on what amaroK can do.
Beyond that, we show you how to make Schenker graphs, master DVDs, replace your TiVo with your own Linux box, squeeze parts of KDE into a small footprint and a whole lot more.

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
