More Mini Book Reviews
When riding the commuter train into Seattle buys me reading time like this, I've got to wonder why anyone drives. There's something about the unhurried ride into work with a good book that makes your day run a little bit more smoothly.
This time around I've got two books for you, Writing Perl Modules for CPAN by Sam Tregar and Linux Server Hacks by Rob Flickenger. This was my first Apress book and the first in a new series by O'Reilly, respectively, so read on and see what I thought.
As with my last reviews, each short review also contains a rating from 1 to 10. (Tens are still reserved for the perfect book, so don't expect to see one any time soon.)
Title: Writing Perl Modules for CPANAuthor: Sam TregarPublisher: ApressISBN: 1-59059-018-X
Sam did a great job with this book, his writing style is informal and fun to read. When I'd finished the book, I almost felt like I'd simply sat down and talked with Sam.
I enjoyed Apress' style as well; the book looked and read like well written documentation. There wasn't a lot of extra mark-up to get in the way of code examples, and the few icons pointed out information that was worthwhile and more useful because it stood out.
The book contains a good deal of distilled wisdom about writing modules. It also covers using C (both with XS and Inline::C), maintaining modules and the process of module submission. At first I was put off by the last chapter, "CGI Application Modules for CPAN", but as I read through it I found myself feeling better about it.
This book is a nice addition to a Perl programmer's bookshelf, so I'll give it 7 stars. It's certainly a nice compliment to Extending and Embedding Perl (reviewed in my last article) and vice versa.
Title: Linux Server HacksAuthor: Rob FlickengerPublisher: O'ReillyISBN: 0-596-00461-3
I was able to sit in on an O'Reilly presentation about a month ago, and I heard Rael Dornfest and Nathan Torkington talk about the new Hacks series. As they talked, visions of mini Power Tools books (my favorite O'Reilly books ever) danced in my head. Given this preconception, Rob had some big shoes to fill--he didn't do a bad job, either.
Rob's writing flows well. By its nature, Linux Server Hacks is a bit disjointed, jumping from hack to hack. Rob did a good job of maintaining order throughout, and the cross-indexing is well done. I wish they'd have maintained the marginal cross-index notes of the Power Tools books, though, instead of the "see also" and inline notations used in this book. I also was disappointed that the on-line source is categorized by chapter number while the book doesn't number the chapters.
A true measure of this kind of book, however, is what you learn from it and what you can share with your friends and coworkers. Linux Server Hacks measured up, and I picked up several new tricks that I shared around the office.
I didn't get the book I thought I would, but I'm happy with what I got. Linux Server Hacks gets 7 stars. I'm looking forward to the next books in the series.
Until next time, good reading and happy hacking.

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
