[HECnet] Number of nodes online a bit low?

[Jason Stevens]

Come to Asia, where you can live the dream of both high volage, *and* crap
wiring.   Not to mention a mixture of fuses, and breakers.   And it seems
every time I pop open anything with a fuse, it's rated for something
insanely high like 13A @ 220V for a simple fan.. 

But at least in HK we don't have the 50/60Hz split of Japan.

You can touch a live wire here and provided it's just one hand and your feet
aren't in salty water nothing much will happen. Higher frequencies will pass
your skin more readily. I'd rather touch 230V/50Hz than 80V/1000Hz.

This is Europe, remember...
Normal mains are 230V, and 3-phase are 410V phase to phase. All the DEC
equipment around here are designed to run on that stuff.

Sure ... I remember reading the back plate on a dryer at a laundromat once
(in I forget which country) and suddenly not wanting to touch it any more.
I just have trouble getting used to the fact that although you *already*
run most things at what Americans would consider double voltage, you
*still*
double the voltage for the big toys (things which we grudgingly whip out
the 230 VAC for). But then again, once it's lethal, I suppose it doesn't
matter how lethal. And copper costs more than insulation so being able
to use wimpier wire for the same wattage is good design. Less loss too.
Plus, this is stuff you pretty much never unplug/replug, so your fingers
are almost never near the live prongs. Still ... around here, it's hard
to find wire that's insulated for more than 300V.

Yeah... That "lethal" aspect have never been my issue. 110V or 230V. Who 
cares? If it comes to the wrong place, either will kill me.
And just through two fingers on the same hand, they both just annoy the 
hell out of me, and I swear loudly for a few minutes...

I am much more nervous about the (to my view) really crappy and scary 
plugs you use in the US. They actually have a fair chance of actually 
exposing me to contact...

You really cannot touch the prongs when they have power on plugs around 
here...
