Using Wikis and Blogs to Ease Administration
There are a lot of blog software packages out there today, but here we cover WordPress. WordPress is fast and has a nice plugin and skin interface to allow you to customize it to your heart's content. The only requirements for running WordPress are Apache, MySQL and PHP. I don't go into how to install WordPress, because the on-line documentation is very clear and easy to follow. Instead, I start where the installation leaves off and introduce some useful plugins. I suggest starting with WordPress v1.5.2 even though v2.0 is currently out. There have been some problems with the initial 2.0 release that warrant waiting for v2.0.1. Also, many of the plugins have not had a chance to update to the new system.
The first thing you should do after installing WordPress is log in as the admin user. Once logged in, you are presented with the Dashboard. At the top of the page is a menu of options named Write, Manage, Links and so on. You should first create an account for yourself by clicking on the Users option. Once that has loaded, two tabs labeled Your Profile and Authors & Users are available under the main menu. Click on Authors & Users, and scroll down to the Add New User section and fill in the text fields. Once your user has been added, it appears in the Registered Users section above. There are several columns of data, and one is Promote, which you should click on. Promoting a user makes that user an author and also allows that user to have more privileges based on its level. Once your user has been promoted, it will have a level of one. There are plus and minus signs on either side of the level to use to increase your user's level. Increase it to nine, which is the highest level a non-admin user can be. Should you ever need to delete users that have been promoted to authors, all you need to do is decrease their level below one and then delete them. I have included a link to a more in-depth description of the privileges of each user level in the on-line Resources.
There are a few other options you might consider changing. In General Options, there are check boxes to allow anyone to register to become a blog user and to require users to be logged in to add comments. You may or may not want these options enabled, depending on your security concerns and the openness of your blog. At our site, users cannot register themselves, though anyone can post comments without being logged in. You should explore all the menus and all their options to tweak them for your site.
WordPress has a very modular plugin system, and a lot of people have written many plugins. WordPress also has a notion of categories. Categories can have many uses, but one might be to create mini-blogs for different communities of users or to group posts about a specific aspect of the infrastructure. But, you might not want all users to be able to see every category. The Userextra plugin, in conjunction with the Usermeta plugin, allows you to control exactly this sort of thing. Once you have followed these plugins' installation instructions, two more menus are available under Options and one more under Manage that allow you to refine access.
Another plugin you may find useful is the HTTP Authentication plugin. This plugin lets you use an external authentication mechanism, such as Apache's BasicAuth, as a means to authenticate to WordPress. This is great if you already have an LDAP directory or Kerberos realm that you use for authentication and you have mod_auth_ldap or mod_auth_kerb up and running.
Many more plugins are available for WordPress from the WordPress Codex and the WordPress Plugin DB. If you feel some functionality is missing, there are plenty of examples and documentation available from the WordPress Web site, and these plugin repositories can help you write your own plugin.
I hope that after this whirlwind tour of wikis and blogs you have come to see how they can be beneficial to help your shop run a smoother ship and provide your users with all the information they might want. Just as there are many different sails to keep your ship sailing, there are many different wiki and blog software packages out there. The right package for you is the one that keeps your users happy and you productive.

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
