A client-based web server application verification and testing system that requires no technical training, yet provides effective and efficient automated testing. The invention facilitates the rapid generation of test cases for a web site, and the automated execution of those test cases via distributed computing. The transitions through a web site are mapped onto a tree control to exploit user familiarity with a dual pane graphical interface and the drag/drop operation on tree controls. The tree is populated primarily by an autonomous spider exploring the site. Complex sequences requiring form inputs are added by recording sample sequences and then allowing the user to prune from all possible permutations of those samples. The export and import of form input data to a spreadsheet provides additional flexibility. Both the exploration and validation tasks may be distributed to a network of computers.

A vibration signal (e.g. a human voice) is generated at a desired pitch corresponding to a tone pitch of a musical tone desired to be generated, and is input via a microphone. The pitch of the input vibration signal and an amplitude (volume) level thereof are detected. When an amplitude level equal to or greater than a predetermined threshold level has been detected but the pitch has not been detected yet, an instruction of generation of a noise tone is issued thereby to generate the noise tone. Thereafter, when a certain pitch is detected, a musical tone is generated at a pitch determined according to the detected pitch. In this way, a noise tone is generated during a delay in pitch detection, and a delay in response at the start of sounding is absorbed.

A filter mechanism for unwanted e-mail messages uses a downloadable central source (1, 2) of filter rule data. User reports of received unwanted e-mail messages are relayed back to the central source of the filter data and used to automatically update that filter data. An algorithmic approach to identifying characteristics of unwanted e-mail messages may be applied based upon the preponderance of predetermined words within an e-mail message or characteristics of the addressee list. If an e-mail message is identified as suspect, but not definitely unwanted, then it may be encapsulated within a HTML document and sent to its addressee together with buttons (28) allowing the recipient to provide feedback in the form of votes as to whether or not that email message is unwanted. This recipient feedback may be used to establish a new local rule.
