Open Source Solutions for Small Business Problems by John Locke
Working for a number of small businesses, I have seen first hand how Linux and open-source software can be used to solve specific problems. It is great to see a good book detailing open-source solutions for small businesses. John Locke takes an excellent approach to this subject by addressing both the business manager who must decide what solutions to implement and the IT administrator who must implement those solutions.
Locke covers all of the software you need for your small business, including e-mail, customer relationship management, finance and disaster recovery. Each chapter provides valuable background information aimed at helping the nontechnical reader understand both the problem and the solution, as well as the details necessary for an intermediate Linux or Microsoft Windows administrator to implement the solution. Locke wisely chooses software that has the features you need, as well as strong community support. He recommends Postfix for e-mail because of its security, performance and feature set. He also recommends RetrieverCRM for customer relationship management and SQL-Ledger for financial management. Most of the solutions Locke presents will run on Windows as well as Linux, for an easy transition into the open-source world.
Although Locke provides good instructions on how to implement these solutions, there is not enough room in his book to provide all of the details you may need. For this reason he provides many references at the end of each chapter, pointing you to books, articles and Web sites that can provide the details you need. Written for a beginning to intermediate user, Locke does a great job of keeping the chapters simple and easy to follow.
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
