The other day in the Linux Journal IRC room (#linuxjournal on Freenode), I was whining to the channel about no-ip.com deleting my account without warning. My home IP address hadn't changed in a couple months, and because there was no update, it appeared abandoned. more>>

Everyone planning and building Web solutions with Drupal benefits from understanding what a "hook" is—and why Drupal is not a CMS. more>>

New Linux users often ask me "what is the best way to learn about Linux?" My advice always comes down to this: install and use Linux (any distribution will do but something stable works better), and more>>

As Linux users, we tend to take programs like GIMP for granted. Thankfully, as of version 2.8.2, GIMP is available as a native application for OS X!
