Using GeShi filter for code highlighting

This website has the GeShi filter installed, so code can be escaped and formated with syntax highlighting. To have your code highlighted you must enclose it in "<code> </code>" tags. Just using these tags escapes the code and formats it as plain text. To add syntax highlighting, set the "type" inside the tag like this, "<code type="bash">. Supported languages are:
Language Name syntax "Type"
Bash bash
C c
C++ cpp
CSS css
Drupal 5 drupal5
Drupal 6 drupal6
HTML html4strict

drupal_goto()

drupal_goto($path = '', $query = NULL, $fragment = NULL, $http_response_code = 302) This simple function initiates an immediate redirect of the user to the URL indicated. The function contains additional parameters to handle complex URL building and supports RFC 2616 by registering an HTTP code for the redirect. The parameters are parsed by this code fragment: $url = url($path, array('query' => $query, 'fragment' => $fragment, 'absolute' => TRUE)); The array is relatively straight forward with the [0] element as the actual address, and the query(if any) loaded into an associative part of the array and the fragments(if any) also loaded into an associative part of the array. The PHP function 'header()' does the heavy lifting in the function by setting the destination and giving the response code to the users browser: header('Location: '. $url, TRUE, $http_response_code);

Linux Foundation Unveils New Linux.com | The Linux Foundation

Check out the newly launched Linux.com site run by the Linux Foundation. It would be nice if their vision came true...


SAN FRANCISCO, May 13, 2009 — The Linux Foundation (LF), the nonprofit organization dedicated to accelerating the growth of Linux, today announced the formal launch of Linux.com. The Foundation took over stewardship of the site in March, at which time it began soliciting input from the community to help define the new Linux.com via its Ideaforge web tool. Today, it unveils the results of that input and a new online home for all things Linux.

The new Linux.com will connect Linux users and developers, and by showcasing their skills through its guru listing, will connect individuals to jobs and collaboration opportunities. Instead of a static information site, the new Linux.com will empower the Linux community to share its knowledge, get questions answered, download the right software and find hardware to solve problems.

MY first NOVALUG blog post

Just an initial blog post on Novalug from me to help get my blog started. I seldom get to attend meetings due to time demands of my family and kids, but I do lurk and participate (when I can) on the listserv. Maybe someday...

I really love using Linux, as I've been using Linux for years, but don't consider myself an expert, especially when comparing my OSS skills and knowledge to most on this list. My expertise is more in the business uses of Linux, as I deal with a variety of customers in that space daily.

About me -- I work for Novell in the Data Center solutions group, supporting a handful of strategic solution provider partners (mostly on the east coast). We focus on Novell products such as SUSE Linux Enterprise Server and PlateSpin management tools. If you ever have questions on that front, feel free to ask me.

Changing your default site theme and/or your blog theme

After registering an account with the site, you may decide you want to go with a brighter theme than the default. So the site has been populated with about a dozen alternative themes that you can set from your user account.

To do this:

  1. open the "My Account" menu
  2. select the edit option above your account information
  3. scroll down to the theme area of the settings and select the radio button of the theme you want
  4. scroll to the bottom of the page, and hit the save button

Your default theme is now changed whenever you log in.

NOTE: You may have trouble viewing all of the "extra" content with a non-standard theme.

Re: Google To Air Chrome Ads On TV... really?!?

Google To Air Chrome Ads On TV

Really? I understand the need to get the word out about a product, but I don't seem to remember any "gmail" commercials. Is this the right direction to go? Should we get used to this? Is google just wasting money?

Open Source Used in this site

This site has been created on an entirely open source stack, from the underlying highly customized Debian Linux operating system, to the Apache web server, to the Drupal CMS everything here was built on open technologies.

Even the site theme(look and feel) is a project which was originally built as a closed source product by Top Notch Themes, which was bought by Dries Buytaert and licensed out to everyone under the GPLv2. The original theme was called "Aquia Slate" but it has been forked into a theme meant to pseudo-emulate the command line terminal called, "Terminal Obsession" which is also open source and can be found at Google Code.
