I am of an age when I notice CHANGE. It is perhaps that I walk more slowly, wait for the green light to cross the road or even notice the increasing cost of using the gentlemen's toilet. Be that as it may, have you noticed that the 19 and 38 bus routes have changed? I only found out on my third journey, because I thought that the buses had been temporarily re-routed. This experience allows me to ruminate on the nature of "Information". We are knee-deep in information, and in order to remain sane one develops an information selective filter. I am working on this device. However, consulting friends with a similar problem I am told that I need a pre-filter. I am at the design stage of such a device and will report any progress in due course.

What does a pre-filter do?
Dear Veronica-- A pre-filter filters before the filter. For example, if there are two tings to be filtered Filter one removes stuff and filter two removes more stuff. The order of filtering is the key to the pre-filter. Whichever filter filters first is the pre-filter. You could be fully accurate and refer to the filter following the prefilter as the "post filter". I hope this answers your question-- Walter Vego
