Mostly, I'm counting on the market to chase the power utilities into efficiency. I live in the US, and realize that this is not am entirely sane to thing to do. Yes, I'm embarrassed about that. resistive heating will never meet the efficiancy of using primary energy directly. I'm not saying don't use incadescent lights if you preffer thier light type but unless your house is heated with resistive heating don't pretend that using them is free in either cost or energy terms.
BTW, plugwash, did you ever get the 'security patches against the generic Linux kernel' problem sorted? It's an interesting problem. nah its something i'd like to know but its not urgent information for me nor is it something i'd have a clue about how to find info on myself. I just made an opertunistic post on/. don't read too much into it.
backfeeding without the proper equipment and without the knowlage of those operating the distribution network can be very dangerous to those working on the network.
net metering also seems like a very dubious idea at best. why should the powerco give you storage facility for free whenever you wan't it?
The modern stuff in continetal europe is actually pretty well designed, its the old unearthed stuff thats got no recess to prevent accidental pin contact thats a problem.
i was under the impression that conventional power supplies (transformer-rectifier-capacitor-regulator) also tended to only take on the leading edge of the top (and bottom if its a bridge rectifier).
normal sockets aren't allowed in uk bathrooms. ELV (below 50V) sockets technically are but are basically never seen. The only non-ELV sockets allowed are special shaver sockets which are transformer isolated and nearly always offer both 110V and 240V at low power.
for switches and other accessories there is a zoning system in bathrooms, whats allowed varies by the zone, switches are allowed in zone 3 and beyond iirc. The reason for pull cords is it allows the switch itself to be located on the cieling which is usually zone 3 or beyond whilst still providing an accesible means to turn it on and off.
this all assumes you are following the IEE wiring regulations which despite what many will tell you are not law.
i'm a brit so maybe your experiance is different but my experiance is that TVs don't power up significantly faster from standby than they do from physical switch-on.
no i think endemic is a better term to use than epidemic here.
my understanding of epidemic was it reffered to something sudden and short term whilst endemic reffered to something that is present long term and unlikely to go away.
my experiance is that such people sit at the back especially in the big lecture theatres that get used for the common first year and common classes in the second year. Sitting near the front keeps you away from such people and makes it easier to read the blackboards and/or projection screens.
The UK socket design is much safer than the US counterpart. i'd certainly say its better but not by a huge ammount. shuttering really only helps with little kids but the fused plugs and tight fit are a good thing imo.
For one thing, there is a requirement that every appliance be earthed, both legal and mechanical. most consumer electronics is class 2 double insulated non-earthed. PCs and white goods do tend to be earthed though.
The live and neutral pins are protected by covers which are only released once the earth pin is inserted indeed that does not however mean that the earth pin is to be connected to anything or even made of metal.
Finally, on all modern UK plugs the tip of the live and neutral pins are exposed, while the end nearest the plug is wrapped in plastic, so if the plug slips out a little way (much harder to happen than with the US design), it does not expose a piece of live metal somewhere easy to touch. most first world countries that use arround 230V have some mechanism to prevent accidental contact with the pins, the europlugs use a flexible plastic section, the schuko and french plugs a recess in the socket, most others use insulation on the pins like the brits do.
Oh, and your original point was about voltage. Perhaps you have never encountered the saying 'It's the volts that jolts, but the mills that kills' - high current is far more dangerous than high voltage, and low voltage requires you to draw more current to get the same power. that expression is widely repeated but highly misleading, what matters is tissue current, route through the body (through the heart is BAD), duration (thats why rcds are usefull they can stop a shock in a very short time) and sometimes frequencey (DC can be nasty because it can freeze muscles, rf has its own special ways of being nasty). Since a persons body won't draw anywhere near enough current to cause significant voltage drop on a mains line the two factors determining tissue current are the voltage and the resistance of the body, the current rating of the cuircuit is basically irrelevent.
deflate is old. the rfc describing it is from 1996 and its very likely pkware were using it before that. The filtering and interlacing systems are probablly newer but are both pretty trivial and could be dispensed with at least for web images if absoloutely nessacery.
most spam i get looks of highly dubious legality at best even in places where spamming isn't illegal.
prescription only meds for sale. big name software at prices so low it seems very unlikely to be legit. nigerian scam type e-mails.
Those are probabblly the biggest categories of english language spam i get, i also get a lot of chineese spam but i can't read that.
the only other type of spam i seem to get a lot of is stuff that advertises spam messages. (note: i don't get virus mails to my inbox as they are deleted server side).
ok so.ca is a bid name and the us would probablly have trouble outright taking it.
however what if the US decided they wan'ted to take gotase.cx and they decided to do it by making themselves authoritive for.cx and then sending requests for all other.cx domains back to the original.cx server?
would all that many people notice and manually override it?

thats true but remember there is a lot more wastage in the conversion of primary energy to electricity than there is in just piping you gas.
some bioses have an option for a scheduled boot that can be set to weekdays only. shutdown could be handled by software running on the OS.

yeah wheras our shaver sockers are transformer isolated ;)
Forget about being able to run a debugger on it. /me looks at the blue device shaped like a hockey puck made by microchip thats on his floor.
true its a little on feature poor side compared to a modern desktop debugger but it certainly exists.
yeah but too see the problem with that attitude just look at copyright.
the combination of harmonisation and lobbying leads to the worlds worst system getting everywhere!
umm JNG wouldn't help you if you can't use JPEG for patent reasons!
deflate is old. the rfc describing it is from 1996 and its very likely pkware were using it before that. The filtering and interlacing systems are probablly newer but are both pretty trivial and could be dispensed with at least for web images if absoloutely nessacery.
Then what Free format was designed to replace JPEG?
none because JPEG was not belived to be free of patent issues.
there has been some challange to this recently by the use of an incrediblly dubious patent, only time will tell if this succeeds or not.
or another seperate one?
yeah but other than gif which is totally unsuitable for photos its about the only alternative we have sadly.
if you are sending sufficiant stuff to the same orbit to pack each rocket to its maximum capacity then cost/weight becomes a very important measure.
iirc they are also pretty damn expensive in terms of network load and login times though...

i'm sure it was some comprimise between a p3 and a celeron or at least thats what ms said it was at the time.
ok so .ca is a bid name and the us would probablly have trouble outright taking it.

they can coexist to some extent.
anyone with full ipv4 internet connectivity to a box they control can get IPV6 connectivity though 6to4. Sadly those behind most home routers can't.
machines can have connectivity to both IPV6 and IPV4 networks.
what isn't possible is communication between V4 only and V6 only hosts.
