It'd take a poet who understood to put my meaning into useful words on this subject. It's about the impractical impossible horribly mistaken dreams of order that people have. Mad people want to impose those dreams on the rest of the world - but it's /mad/, because the universe is. And whatever it is, it's not cruel - it's neutral; it's not ugly - it's the sum of all beauty; it's not write-only - as any number of scientists could tell you; and its obscurity is one of its glories. The universe *IS* - and we are too small and too silly to significantly affect it in any way at our current stage of evolution and understanding and technology. Try some Hawkwind for size: Space is dark it is so endless When you're lost it's so relentless It is so big, it is small Why does man try to act so tall Is this the reason Deep in our minds It does not feel it does not die Space is neither truth nor lies Into the void we have to travel To find the clue which will unravel Is this the reason Deep in our minds The secret lies with our tomorrow In each of us is a hidden sorrow The path goes onward through the night Beyond the realms of ancient light Is this the reason Deep in our minds Rowland. P.S. This might lift your mood slightly, if you've just listened to the above track: Well we had a lot of luck on Venus We always had a ball on Mars Meeting all the groovy people We've rocked the Milky Way so far We danced around with Borealis We're space truckin' 'round the the stars Come on let's go Space Truckin' Come on Space Truckin' Remember when we did the moonshot And Pony Trekker led the way We'd move to the Canaveral moonstop And every 'naut would dance and sway We got music in our solar system We're space truckin' round the stars Come on let's go Space Truckin' The fireball that we rode was moving But now we've got a new machine Yeah Yeah Yeah Yeah the freaks said Man those cats can really swing They got music in their solar system They've rocked around the Milky Way They've danced around the Borealis They're Space Truckin' everyday -- Remove the animal for email address: rowland.mcdonnell(a)dog.physics.org Sorry - the spam got to me http://www.mag-uk.org http://www.bmf.co.uk UK biker?

Can you be more specific about > what you are puzzled by? I'm top-level baffled, can't get started understanding things, due to a failure to understand stuff - stuff? I don't know what. I'm that baffled. 10.0.0.0 block I mean, what's that all about? I don't know what 192.168/16 block means. I just don't get it. Yes, yes, I've read reams of stuff on-line. I still don't get it - it's all using terminology that I cannot work out, and it's pretty much impossible to learn about this sort of thing from written sources. The only way is if you can find a kind person to explain - it's all about excluding people who don't have the right contacts. The American way, you see.

The range of IP addresses from 192.168.0.0 to 192.168.255.255 Each group of 4 numbers is an 8-bit number (0-255), so the /16 means '16 bits'. Hence, 192.168/16 means 'any IP address starting with 192.168' Jim -- "Microsoft admitted its Vista operating system was a 'less good product' in what IT experts have described as the most ambitious understatement since the captain of the Titanic reported some slightly damp tablecloths." http://www.thedailymash.co.uk/ |
