The above may appear to paint a rather bleak picture—to some extent, this is justified. The types of operations performed by PartitionMagic are inherently dangerous and bugs in such a program are a serious matter. On the other hand, my suspicion that the bugs manifest due to something specific about my system may mean that others may have better luck. PowerQuest also has a good reputation for producing reliable software, so I have high hopes that they will correct these problems. Assuming this happens, PartitionMagic 4.0x will be an excellent program and a must-have utility for anyone managing multiple operating systems on one computer. The $69.95 price may seem a bit high, but if you have ever spent most of a day juggling partitions around using tape backups, removable disks or some similar mechanism, you'll recognize the appeal of being able to do that quickly and on the fly. If you own a previous version of PartitionMagic, the $29.95 upgrade price represents a true savings for any Linux user, since it radically improves on the program's utility for the Linux community.
The best possible way to use PartitionMagic seems to be as an exclusive means of managing partitions on a drive. Because of incompatibilities such as the one mentioned above with Linux's fdisk, I recommend using PartitionMagic to create all the new partitions on a disk. If you find yourself with a disk that PartitionMagic won't handle because of Linux-created logical partitions, you may be able to use Linux's fdisk to delete the offending partitions and recreate them in the correct order. If you're careful to create new partitions of precisely the correct size, your partitions will still be usable, but I strongly recommend backing them up before attempting such an operation.
If version 4.01 is not available by the time you read this, I recommend waiting for it unless you are in immediate need of Partition Magic's abilities. If you must use version 4.0, use it cautiously: back up all data before changing a partition, then run e2fsck, CHKDSK, or SCANDISK on any modified partitions immediately thereafter. (You may need to specify the -f option to e2fsck to be sure it runs on the partition.) A spot check of the integrity of the data after a modification would also be a good idea. Of course, these suggestions also apply to any program that does low-level operations on a hard disk, but given the problems I encountered with PartitionMagic 4.0, they apply even more strongly to it.

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
