Obsolescence is a state of being which occurs when a person, object, or service is no longer wanted, even though it may still be in good working order.
Types of obsolescence
Technical or functional obsolescence
Technical or functional obsolescence may occur:- When a new, more functional product or technology supersedes the old (example: telegraph to telephone)
- When the product becomes useless due to changes in other products. For example, buggy whips became obsolete when people started to travel in cars rather than in horse-drawn buggies.
- When spare parts become so expensive that it becomes more attractive to purchase a new item
- When poor quality materials shorten the product's lifetime
- When component parts are no longer available to enable the manufacture of an item. Management of this type of obsolescence is required if long-term product availability is important.
- When new products alternative to another are smaller and serve similar purposes; for example, the 3 inch floppy disk thwarted 5 inch floppies out of production because the physical size was smaller and it had more binary volume both by max capacity and proportionally more volume, hence the smaller physical size. And compact discs also obsoleted 5 inch floppies because they had significantally more binary space, but were similar to the physical size of the magnetic disk on the 5 inch floppy disk.

Virtual Hosting With Proftpd And MySQL (Incl. Quota) On Fedora 9
Sat, 19 Jul 2008 21:30:49 -0000
"This document describes how to install a Proftpd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota with this setup."

Perl and Bash Versions Of Binary To Decimal Conversion Script
Sat, 19 Jul 2008 13:30:49 -0000
The Linux and Unix Menagerie: "As promised, in yesterday's post on converting binary values to decimal in C, today we're going to follow up with straight-up ports to Perl and shell. Actually, they'll be slightly different. If you check yesterday's post, for some reason I left in a variable called "difference" which was a part of the code I mentioned that I had originally written to pad 0's on the left hand side of a binary number less than 8 digits."
