My Experiments With Life
Often times, a need arises where one has to search a bunch of arrays to find out to which one of them a given element belongs. Of course, life becomes a lot simpler if those arrays are unique (meaning any given element appears only in one of the arrays) and life may not always be that simple.
It might, at some point in a WordPress powered blog, become necessary to a show some widgets/stuff in some places (the main page, archives, etc.) while show a different set of widgets/stuff in some other places (static pages – about me, product reviews, etc.). To keep track of things and may be understand the process better, let us suppose that only those pages written in Product Reviews Template will use a different sidebar (Sidebar #2) while rest of the blog uses a common sidebar (Sidebar #1). Thanks to my dear friend, Amy – if not for her, I probably would have never learned about this hack.

Expect is a UNIX automation and testing tool, written by Don Libes as an extension to the Tcl scripting language, for interactive applications such as telnet, ftp, passwd, fsck, rlogin, tip, ssh, and others. It uses UNIX pseudo terminals to wrap up sub-processes transparently, allowing the automation of arbitrary applications that are accessed over a terminal. With Tk, interactive applications can be wrapped in X11 GUIs. Expect has regular expression pattern matching and general program capabilities, allowing simple scripts to intelligently control programs such as telnet, ftp, and ssh, all of which lack a programming language, macros, or any other program mechanism. The result is that Expect scripts provide old tools with significant new power and flexibility.
One of the most primal needs of displaying strings as an image is during form submission and to make sure that a human being (although there is a finite probability that a monkey can accidentally type the same string correctly) types in the string. This form submission can be to accomplish one of many things – posting comments, placing web orders, displaying email addresses, etc. For my recent, still on-going, attempts to write a personally satisfying photoblog software/application, I need this as part of comment-submission process.
