Regular Expression Engines
A regular expression “engine” is a piece of software that can process regular expressions, trying to match the pattern to the given string. Usually, the engine is part of a larger application and you do not access the engine directly. Rather, the application will invoke it for you when needed, making sure the right regular expression is applied to the right file or data.

Goodby Sparc
My Sparc 20 has been with me through many other relationships. She never got jealous of my other machines and she never once let me down. Her 9GB external hard drive enclosure and her Solaris OS were always there for me, and before she was mine she hosted one of the top 1,000 web sites in the country (of course, that’s back when a whole site could fit on a whopping 9GB external enclosure). She was my “old-reliable”. But alas, all good things must come to an end. There’s a chance that she would have lasted forever if I had her plugged into a better UPS. It wasn’t her fault…
