- The talk about static on AM radios being useful is only the tip of the
- iceberg. Let's suppose you are blind and you have given your PC
- something monumental to do such as sort a large amount of data or
- search for a key word in a huge document. Two things can happen which
- can drive someone to strong drink. The software may print a running
- status message, telling you that all is well each time it does
- something right. Who wants to be told 5,000 times that everything is
- OK? Some program setups may do their work silently, but one wonders
- if the machine is sleeping or working. If it takes 30 minutes, for
- instance to search a huge document for a key word, one doesn't expect
- to hear anything for a while. If something terrible happens like a
- crash, the effect sounds the same until 45 minutes, 50 minutes, etc
- have gone by and you realize that the whole time has been a waste.
-
- Hear's the fix. Take a portable AM or FM radio and place it
- near the computer. Tune around until you find a whine or buzz that
- suits your ears. It should be possible to find a signal which varies
- when the computer is doing something and stays relatively monotonous
- when it is hung up or idling.
-
- One doesn't have to have golden ears to be able to tell when
- it sounds like things have gone sour. This trick has also proved
- useful when doing long file transfers as it is possible to hear
- disturbances in the noise from the machine when data are coming in.
- By using a little common reasoning, one can even get some idea of
- whether or not there might be a problem with the data stream by
- listening to the cadence of packets and noting whether they seem to be
- steady and not halting or ragged. Try it, sometime.
