Focus on Software
I don't know if any of you have had the need to set up a diskless workstation on a system served from another Linux system via TFTP. I remember the ordeal well. The HOWTO was woefully inadequate in many parts. So, I decided to repeat the experiment using ltsp. In just about 30 minutes, it was up and running. Okay, so I had a head start having done it once before. Drawback: unless you're running Red Hat, Debian or Caldera, be prepared to do it by hand or hack the install scripts. (That's what I had to do on my Caldera system because it didn't understand Caldera 3.1, only 2.4.) Requires: installed and running XDM, KDM or similar, DHCP server, TFTP. Workstation capable of a network boot or floppy boot.
Tax time is past, but it's coming around again fast. And while gTaxEstimator isn't yet ready for prime time, it could be by next tax season. Personally, I'm hoping for support for Schedule 2555 soon. The interface is simple and clean. This is probably the most promising piece of software I've seen in a while. Let's face it, if you live in the US (or even if you don't but are a US citizen), there's no escaping the Internal Revenue Service. Requires: libgtk, libgdk, libgmodule, libglib, libdl, libXext, libX11, libm, libz, glibc.
The mkCDrec utilities allow you to do several different things. They allow you to make an el-torito bootable CD for system rescue. They also allow you to back up your entire system to multiple CDs. You'll also need the mkCDrec utilities if you want to do system restores. You can backup systems that don't have burners, either by creating the iso image(s) and transferring them for later burning or using NFS to write the ISO image(s) to the system with the burner and burn later. Either way, this utility is convenient. Requires: Running system w/ mkisofs gzip, access to a system with cdrecord, mkisofs, gzip.
Until next month.

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
