Sound with even harmonic distortion is said to sound warm, that is 2f,4f,6f etc. Sound with odd harmonic distortion sounds harsh to our ears, that is 3f,5f,7f etc.
Valves usually produce even harmonic distortion, transistors usually produce odd harmonic distortion.
The difference here is that Iridium was in Low Earth Orbit (780Km), and would allow short delays, this is in Geostationary orbit (36000Km) so you get delays in the order of 1/2 second, for every packet handshake.
Using standard TCP/IP is a non starter. But while this is a technical problem, Iridium was more of a business problem, too expensive to launch 66 sats for what a few people would pay. If it had got to millions of users, then it might have worked. It was a phone service not a Data service.
The economics for this will be better for all those connection hungry remote users, just dont think it will be like real DSL.
Yeah, but unfortunately some of the people who you will buy goods and services from will use the stuff, so you will pay for that, just one level of indirection:)
>And to the folks that corrected my terminology: yes, I know "Z" or "UTC" is the more correct term, but old habits die hard.:-)
Well actually its not:)
The UTC (or Universal Coordinated Time) scale is an atomic timescale by universal agreement, that is, everyone compares their atomic clocks and adjusts towards the common agreement.
While GMT is an astronomical timescale from observation.
This means UTC is pretty constant while GMT might move around a bit with the decaying orbit of the earth.
Over long periods GMT usually falls behind so every few years we have a Leap Second to bring them back into approximate alignment.
So we use UTC for all our time measuring, but we need to monitor GMT to know when to correct UTC, otherwise they would slowly drift apart.
But to a 'less than a second' approximation, they are about the same.

I think you'll find the UK telephone system needs different settings and approvals and therefore its not viable for the UK market, they dont seem to sell any modem products in the UK.
That said, it would probably work if you got one:)
Anyway ignore the 56k, think of all the good hacks you can do with it, ethernet-serial must be easy...

Your welcome.
>> Doesn't AJAX mean 'Async. Java And XML'? So can you have AJAX based on something else?
Javascript not Java, so yes, you can have AJAX based on something else.
Well yes!
Have you ever seen a seagull with ailerons and flaps ??
Well we seem to have slashdotted XGI at http://www.xgitech.com/
:)
So I'm sure they are getting good feedback
Now if their sales increase at the same rate...
Or for the open source version ..

Now try it on google and you get articles about the 'more evil that....' debate.

How about that? Cheap, hackable, ugly and fun...

Perfect!

Ob Python quote seems strangely appropriate
Yes, its called Web Services, SOAP et al, just wrap some XML with some binary inside...
Oh by the way all your firewalls are useless and you need to inspect all data in a packet before you let it in...
And so it goes on...
Yeah, but unfortunately some of the people who you will buy goods and services from will use the stuff, so you will pay for that, just one level of indirection :)
Your still gonna pay I'm afraid...
While its a virtual monopoly you cant avoid it.
Until everyone gets a clue!

So is the word 'effectively'

I agree, I watched the BBC TV News on the subject and they kept referring to 'clips'.
I think there are many old jewels still there we may get hold of though!
