Anatomy of the Linux virtual file system switch or donate; car & computer technology
With the Linux virtual file system switch (VFS), you can create file systems on a variety of devices, from traditional disk, USB flash drives, memory, and other storage devices. You can even embed a file system within the context of another file system. Discover what makes the VFS so powerful, and learn its major interfaces and processes. Understanding the dynamics of such a system will benefit you in the long run. In today's ever growing technological era you must try and stay up to date with new ways of storing data. People transfer and carry data all different ways, and it is important that you are able to access that data even as technology changes. These days you will upgrade technology at a very fast pace. For consumers, it almost becomes a necessary thing. It is OK to donate car technology and other outdated systems in order to move with the times.

Worry-free Linux power-downs with Anacron
Linux ordinarily uses Cron to automatically perform routine system maintenance on desktop or laptop computers, however not running Cron routinely can result in monstrously large log files and other problems. You can offload most or all of your usual daily and longer-interval Cron jobs onto Anacron enabling your computer to run regular maintenance jobs whenever the computer is powered on, even if those times are unpredictable.

HOW TO: Teach your old Mutt some new tricks
Was always a pine fan before I went to Gmail.
"Many geeks ditch the heavy graphical or web-based mail clients for a lean, mean solution: mutt. Mutt’s a character-based Mail User Agent (MUA) that snaps to your every command. It also provides powerful features for customization, organizing large volumes of email (especially from mailing lists), and interfacing to other applications."

Unix turns 40
Nice retrospective by computer world.
"After batting around some ideas for a new system, Thompson wrote the first version of Unix, which the pair would continue to develop over the next several years with the help of colleagues Doug McIlroy, Joe Ossanna and Rudd Canaday. Some of the principles of Multics were carried over into their new operating system, but the beauty of Unix then (if not now) lay in its less-is-more philosophy."

Using PHP directly from the command line on Linux

Learn how to better integrate scripts with command-line tools. Examine using shell_exec(), exec(), passthru(), and system(); safely passing information to the command line; and safely retrieving information from it. If you are looking to monetize from a website without the PHP knowledge, you can always try an online membership website builder.

See how to integrate closely with underlying shell commands and folding any return values into your interfaces and processes.

Modify xorg.conf for better performanc
Some nice info in this.
"Most of the time, your screen's capabilities should be identified using something called EDID - Extended Display Identification Data. This is a chunk of information sent from your display to your graphics card, and normally contains information such as your screen's model and manufacturer, resolution timings and display size. X then uses this data to create appropriate resolutions and bit depths that make optimal use of your hardware."
