are we talking about IM systems (AIM, MSN Messenger, Yahoo, ICQ, IRC)
Or are we talking about message QUEUING systems like... erm... MQ
Used them before - they're way cool. Used to have a bunch of iPlanet & Apache servers talking to weblogic boxes which used MQ to talk to NT boxes running Universe and some thing or other in C somewhere else. There were big drawings and maps on the wall and it all made sense to whoever was in charge but the rest of us just looked on, shrugged shoulders and got on with it.
Rebooting was the funnest though - having to take down everything so the NT boxes could be rebooted then all the Queues brought back up:)
MQ - a way to tie multiple tiers of dysfunctional software on inompatible hardware into a big ball of system fluff.
they never are. We know a collapse will happen but even when it's the big one we won't know it's going to happen til it starts to happen by which point it is too late.
Crying wolf with something like this is not a good idea.
all be it on a far smaller scale, we've just seen a large tsunami cross thousands of miles of ocean from the east side of the indian ocean to its west side and drown half of Sri Lanka and western India. It's no use sticking your fingers in your ears shouting "la la la not listening". Most of the Indian ocean is not 10 miles deep, it's mostly 4-6 miles deep which is about the same as the Atlantic.
I take your point about the positioning of the source of the wave - the Indian Ocean tsunami occured at ocean trench depth. Whereas the Canary Island Tsunami will occur due to a displacement above sea level. However the 500 cubic kilometres of rock being dumped straight off the continental shelf (because the Canary Islands are right at the edge) would effectively be like dropping a very big penny in a very big pond.
The mid-Atlantic Ridge at its highest point is still 4 miles below the surface of the ocean. It will dissipate some of the energy - which is why the original 1800 foot waves may only be about 100 foot when they hit the eastern sea board. Mind you as it continues on its way passed the mid-Atlantic ridge and rolls down the other side it will have an opportunity to amplify down to greater depths so who knows?
1.) Tsunami waves radiate from a point source or a line source exactly like ripples on a pond
2.) Like ripples on a pond they don't tend to break (form a big wall and roll over) until they reach the edge.
3.) Most of the death from the Aceh tsunami are from the bigger waves that follow the initial hit. The wave length can be anything from 5 to 45 minutes (which on a wave doing 450mph is 37.5 - 337.5 miles)
4.) Wave heights mentioned in the article above are extrememly conservative. From some of the data I heard from Bill McGuire when I was at UCL, the initial wave could be up to 650m (1800+ feet) attenuating to 200m (600+ feet) by the time it reaches the eastern sea board.

careful fella you nearly made me choke on my matzah.
