Well, as long as we are griping, my biggest problem with residential cordless
phones is their current size. What seemed to start out with one country's
fascination with all thing microsized has been amplified by a desire to mimic
cell phone dimensions.
It would be nice if phone manufacturers did a little human factors analysis of
their designs...

My new handsets are 6.5 inches long by 1.5 inches wide. That's not
quite cell phone size.

Didn't they have ear plugs back in the day? Back in the 1970s I
worked in the canneries and wore ear plugs to keep my ears safe. I'd
think that a person has at least some responsibility in protecting
themselves against hostile environments.

You are assuming that soldiers have the world-view of civilians, and
that's just not true: it never was, and it never will be true. It
can't be. Soldiers face the responsibility of protecting themselves
against hostile environments by preparing their minds and bodies to
kill the hostiles, and the mental discipline which is essential to
becoming a soldier colors soldiers' and veterans' tolerance for risk
forever.
>From the moment they arrive at a recruiting depot until the moment
they leave the service, the military hammers a message into the
frontal lobes of every recruit, : "You are immortal! You are
courageous and fearless! All your relatives and friends envy you!"
It's how old soldiers are able to make young ones sacrifice their free
will, their humanity, and their lives in furtherance of goals that
only politicians can understand and only soldiers can achieve: you
don't get to turn that off like it's an assembly line. In addition,
the weight of tradition impedes progress in all aspects of military
life: it's easier to train the recruits to "Call out your numbers loud
and strong" than it is to provide hearing protection.
We owe veterans the compensation which they're entitled to, because
they gave up the right to complain about the noise or to complain
about the food or to complain about the danger, and accepted the need
to sacrifice their individuality, and even their instincts for
self-preservation, in order to learn how to slay our nations' enemies.
If you think that I'm not making sense, just imagine that in your
cannery, every One Hundred Thousand cans or so, one of them would
explode and kill every cannery worker within twenty meters. Imagine
that you couldn't change that number, that you couldn't reduce the
risk, and that you couldn't quit the job. _Now_ how much are you
worried about your hearing?

I have mixed emotions when I read something like the following
which appeared on Slashdot earlier today, especially given the
known GSM interference problems.
However, this is telephony and this is news (from Slashdot):
Harald Welte, who's been interviewed previously by Slashdot,
has written on his blog about operating an Open Source GSM
network:
http://laforge.gnumonks.org/weblog/2009/08/14/#20090814-har2009_gsm_network
at the recent HAR2009 conference:
https://wiki.har2009.org/page/Main_Page
Photographs and a description and of the setup, run under
license of the Dutch regulatory authority, are provided;
essentially the setup consisted of a pair of BTSs (Base
Transceiver Stations) running at 100mW transmit power each
and tied to a tree. In turn these provided access to the
Base Station Controller (BSC), in this case a Linux server
in a tent running OpenBSC:
http://bs11-abis.gnumonks.org/trac/wiki/OpenBSC
The system authenticated users with a token sent via SMS;
in total 391 users subscribed to the service and were able
to use their phones as if they were on any other network.
Independent researchers are increasingly examining GSM
networks and equipment, Welte's work proves that GSM is
in the realm of the hackers now and that this realm of
mobile networking could be set for a few surprises in
the future.
[ We need to keep an eye on this; "a few surprises" could mean
many different things :-) ]

Are you sure it's not just that kids with poorer memory and slower reaction
time are more likely to use mobile phones rather than other media?
