The Oddmuse Wiki Engine
Oddmuse is a single Perl script. This makes basic installation straightforward and supports another of Schroeder's project goals: to keep Oddmuse simple and easy to use. The potential loss of flexibility is offset by Oddmuse's extensibility. As evidence, you can find a list of available modules on the project Web site.
Aside from the ordinary, requisite wiki features, such as automatic tracking of recent changes, powerful linking syntax, revision control and visual diffs of revisions, Oddmuse has a number of notable features and advantages. One of the first things that impressed me about Oddmuse was the quality of its documentation. Schroeder makes abundant documentation in an assortment of languages a priority, and it shows. Conveniently, he gets to use the tool he's documenting to write and maintain the documentation. A visit to the Oddmuse project Web site is both a demonstration of the engine in action and an encounter with ample information about how to set up, use and customize it.
As someone who strives to adhere to World Wide Web Consortium (W3C) standards, I was pleased to note that Oddmuse produces valid HTML 4.01 Transitional. On a related note, Oddmuse integrates nicely with Cascading Style Sheets (CSS). If you're interested in syndication by way of RSS, Oddmuse supports both an outbound RSS feed for your wiki and inbound RSS feed aggregation.
An obvious concern for any wiki is page vandalism. What, after all, is to prevent someone from editing a page and intentionally making a mess of it in one way or another? If you want to take full advantage of wikis' biggest strength—namely, that anyone can create and edit pages—simply leave the system open and revert defaced pages as they appear. An attentive group of editors can catch vandalism by monitoring the RecentChanges page.
If, on the other hand, you prefer to forgo the advantages of open editing and would prefer to prevent vandalism in the first place, Oddmuse provides two methods for doing so. You can lock specific pages or the entire site and use passwords to grant page editing permission to certain individuals. Your other option is simply to ban problematic users.
Oddmuse uses flat files for data storage rather than a database such as MySQL or PostgreSQL. A good argument can be made for why this is a strength, and an equally good argument can be made for why this is a weakness. On the one hand, using flat files instead of a database means more simplicity and less administrative overhead. On the other hand, databases provide advantages when it comes to data storage and retrieval. If you feel that you must have a database behind your wiki, then Oddmuse is not for you. However, if your concern is speed, it's worth noting that searches are reasonably fast, for instance, on the Emacs Wiki, which uses Oddmuse and currently has 2,242 pages.
The installation section of the Oddmuse Web site has links to the latest version of the script and guides to installing and configuring it. Basic installation is absurdly simple. Once you've downloaded the script, simply place it in your CGI directory and make it executable. It should work immediately. If it doesn't, consult the troubleshooting guide on the Oddmuse Web site.
Even if you have no plans to customize your wiki, you should make one important change before you do anything else. Namely, you should change the $DataDir variable in the script to the absolute path of the directory in which you would like Oddmuse to store its data. If you don't change this variable, Oddmuse uses /tmp/oddmuse as its data directory, and you could lose your data down the road.
Another step you should take, no matter how simple or complex you intend to make your wiki configuration, is setting the administrator and editor passwords. The variables to change are, respectively, $AdminPass and $EditPass. Because the passwords are stored in plain text, the security of your wiki is only as good as the security of your server in general. Nonetheless, you should pick strong passwords.
Although the basic installation provides a fully functional Oddmuse wiki and may be all you need, you might want to consider the more-advanced installation. I chose the more-advanced installation for the Oddmuse wikis I've set up recently, and I've found that the added flexibility is well worth the trivial amount of additional effort required during its setup.
First, I used the wrapper script strategy clearly explained on the Web site. This strategy eliminates the need to define the data directory pathname every time you upgrade the script. Second, I used an external configuration file, and in it I specified an external CSS file.
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
