Other appliances, generally those with electric heating elements (such as a range, water heater, furnace, machines such as a tablesaw) run off dedicated 220V circuits.
Every appliance you mention, with the exception of the washer (which receives hot water from the water heater) runs on 220V in the US.
Admittedly, I'm an American but I will back up my points.
220V is too much for everyday electronics. Why does your vacuum cleaner or table lamp need 220V? I do understand that the amperage is lower (half) for the same wattage. However, if there's a fault in an appliance, and the current carrying lead is exposed, you can touch the conductor without anything more than severe discomfort (wouldn't even call it pain - this has happened to me with a bad light socket). I doubt you could pull this off with 220V. Obviously completing a circuit on either is a bad thing (touching between current and ground...)
Second, ring circuits are for very specific things. I understand the UK uses a ring circuit for pretty much every floor. In the US, we use home runs for important things and limit ring circuits to, say, the 4-5 outlets around the perimeter of the room, generally one room, about a foot off the floor. Those usually run at about 15 amps - enough for a powerful vacuum cleaner, but generally not a microwave. Those run off a (dedicated) 20A circuit, same as a fridge. Other appliances, generally those with electric heating elements (such as a range, water heater, furnace, machines such as a tablesaw) run off dedicated 220V circuits.
The upshot of this is the US has many more circuit breakers, and a lot more granularity. A typical house has about 30-40 circuit breakers, maybe more. But a circuit breaker controls, say, half of a room - instead of the entire first floor. UK plugs are fused, so the appliances are about as safe, but that doesn't fix the problem of not wanting to disconnect a whole floor to work on the electrical system. And you start limiting the current from the distribution point - if you drive a nail through a wire, it will only be carrying 15, maybe 20A before the circuit breaker blows. That's opposed to the 220V at 40A...
Basically, in general there's a lot less current flowing through people's walls. The appliances that need more power get their own entire circuits. I can't help but feel that this is safer, and it allows us to reduce the complexity of our plugs.
I'd honestly like to hear why people disagree - as I'm sure they will.
The AT&T Mobility wireless data network began in 2002 as a Cingular initiative called "Project Genesis" that involved a GPRS (General Packet Radio Service) overlay of the entire wireless network. Project Genesis was completed by the end of 2004. Later, this network was upgraded to EDGE (Enhanced Data rates for GSM Evolution) across the GSM footprint.
I don't want my friends to take my songs and mix them. I'm fully aware that it's legal today.
Look, that makes you a jackass. Worse, you're a profiteering jackass. You care that your friends remix your songs? Some friend you are... Honestly, I'm surprised you have any. With that attitude, I'd be ashamed to know you.
Bullshit. Any jackass can search for #darpaballoon on Twitter, and graph the traffic, without needing wiretaps. The rest of this is all necessarily public as well.
Chill out a bit. This is DARPA; they're cool. And this is an awesome idea.
Well, not necessarily. A good backup client (I don't know about Carbonite or Sugarsync) should encrypt, with industry-standard algorithms, on the client side before sending it to the server.
You (perhaps) joke, but this is a real problem. In context, a bug in one program would be a feature in another...
This is a trivial example, but imagine a program designed to segfault: int main() { char* p=0; char x=*p; }.
How do you fix this? What's correct? Do you assign p to a safe value? If so, what? Do you simply remove the assignment of x? What about anything downstream that uses x? What if you wanted it to crash? What if p was assigned by a function (scanf)? What should it be?
Without knowing the purpose, intent, and processes of the program, this simple bug is unfixable. A human could say "I meant to assign p" or "scanf shouldn't be giving me null..." or even adding a conditional that spits out an error message and continues.
In a sense, these programs fail because their behavior is undefined. And it's undefined for a reason - there's many states it could be, and one it should be, and it's not matching up.
Yes, but most of those are static errors and can be/are found with lint or your compiler. Admittedly some similar improvement can probably be made with dynamic errors (exceptions, etc) but this can only be extremely limited. To fix any non-trivial dynamic errors like this requires a fundamental understanding of what the program does and how to do it... this is hard for programmers. A deterministic, non-intelligent computer could never do this work.
I grew up and live in NJ, albeit a really nice part. The only general complaint I have about NJ drivers is that they consider the turn signal a sign of weakness - as a rule, if it goes on at all it's in the middle of a turn. I'm an excellent driver (I drive a 7-ton ambulance safely with no trouble), and I can count on one hand the times where I haven't signaled, in the two years I've been driving.
In any case, there are bad drivers anywhere. There's a lot of people in NJ; you'll tend to see more of them per mile...
What's with all the NJ hate? Parts of it are grimy and will get you shot (Irvington) but that's true anywhere... Maybe it's the governance? We haven't had a non-corrupt governor in like 10 years... yet things work out.
That's a terrible idea. How the hell could you ever drive on the street? And what happens when TWC "accidentally" nicks Verizon's fiber?
Do you simply not live in the real world? There are physical limits here. There can only realistically be one provider ripping up the streets; at the moment that's a private company. It should be the government who then leases it out.
Something similar happens with DSL. Verizon owns the copper to my house (and happily provides crappy DSL service over it) but are legally required to allow anyone else (in my case, ATT through Covad) to hook up their stuff in the DSLAM. So my internet is Covad, and my router talks to them.
Why not replace Verizon with the government? In other words, remove the natural-monopoly property for infrastructure - it's not trivial to run your own broadband company, but it's certainly achievable.
Wait, the only difference between Windows CE and Windows NT is the APIs exposed, and the instruction set? That's true between Mac System 7 and Linux.
I think what you meant was that the APIs are very similar, or perhaps that CE is a subset of NT. Most of an OS (as far as an application is concerned) is the API.
That's why I have a DVR - Discovery is now crap. There's still some quality stuff on there - Mythbusters of course (they seem to be getting more intelligent! who'da thought...), Dirty Jobs is generally interesting and surprisingly informative (though more than a little silly), and Time Warp is interesting despite their best efforts (perhaps not for long). The Raging Planet things they did a while back were really good, too (lightning, floods, hurricanes, etc)
In short, it used to be amazing and educational/informative, but they seem to be actively fighting that. The erstwhile top-notch shows have gotten more and more stupid - I'm know the Mythbusters aren't stupid, but they're acting like it, undoubtedly due to pressure from the top.
And then there's utter bullshit like Ghost Lab and A Haunting. It's a discredit to the good shows to be on the same network as that excrement.
Oh well. It's a shame - they have a core base of the scientific intelligentsia, and they seem to be working their very best to kill it off.
You don't have the least idea what you're talking about either. So don't you be telling people to 'know what the fuck [they] are talking about'
This flu, like many diseases, is transmissible several days before symptoms. Staying home doesn't work - you only stay home when you feel sick, which is 2-3 days too late.
Face masks are far from perfect. I've been fit-tested for respirators, and they're good but not perfect. Plus coughing tends to blow the mask away from the face, don't you think?
Hep B is a danger to the health care worker. Not getting flu vaccinated makes the health care worker a risk for everyone in the hospital, particularly the sick.
I have a lot of respect for Barry Goldwater. To anyone too young to know about him (like myself... though I've studied him) he essentially said "let's cut social programs to cut taxes" and got rode out on a rail.
In a classic Reagenesque move, Reagen came in and said "Let's cut taxes!!!" and everybody thought that was the greatest thing ever. Reagen then "discovered" that there suddenly wasn't enough money for all these social programs so they'd need to be cut - as if he didn't cut taxes to "force" himself into that position in the first place...
At least Goldwater said what he wanted. In what has become typical politics, Reagen came in and said something different than what he wanted - but something he knew nobody could object to. As a only-slightly removed result of that, he did what he want.
Does everyone around here have shit-for-brains? Jesus
Swine flu might not be so deadly, but it's a hell of a lot more virulent. If 1% die from each, but 70% get swine flu vs. 30% normal flu, what happens in absolute terms?
Second, there should be absolutely no debate, and absolutely no compromise that anybody in health-care should be getting their vaccines. What's so hard about this? "Boo hoo, I don't want a vaccine because of x,y,z pointless and unsubstantiated reasons" does not stand up to "you being sick will kill people". If somebody doesn't understand this, they are too stupid to work in healthcare and need to get out.
Third, what kind of a stupid question is that? I'm not vaccinated against malaria because it's extraordinarily unlikely that I will contract it. You said so yourself - "the chances are really low". However, it is quite likely - probable, in fact - that I will get swine flu if I'm not vaccinated.
Jesus. None of this stuff is particularly hard to understand. The swine flu vaccine is made the same way as the normal, harmless flu vaccine. The way it's made is what would make it dangerous, not its payload. And yes, in edge cases some people will have an adverse reaction to the vaccine - but that's true of peanuts and oysters as well, and in much greater numbers.
THIS IS NOT COMPLICATED! If enough people are vaccinated and DON'T get the swine flu, we won't have a pandemic. If not enough are, we will. It's not a mortality problem, it's a infrastructure problem. If ten million people are in the hospitals this winter because of a pandemic (as opposed to the usual 200K) people will die because hospitals will be swamped.
Don't you fucking dare assert that you may be fine and that's all that matters, because nobody cares about you. Us who actually can see the consequences of behavior see that if a significant proportion of people get sick from ANYTHING, be it the cold or Ebola, it will fuck over the world, the economy, and thousands to millions of unrelated people.
I don't think he meant "remove support for ports". You already don't need to specify a port - it's 80. Just change it so that you look up the SRV first, then use port 80 - if the port isn't specified in the URL.
Just remove the need for alternate ports. You can use them if you want, but not by necessity.
To borrow from a recent argument, truly you share the eloquence of Cyrano. In a similar vein, fuck off - at least with the insults.
Remember, you don't say port 80 to go to Slashdot. Why not default to the SRV record (then port 80 for backwards-compatibility) unless the user specifies otherwise?
No. You did smtp over TCP/IP, which happens to be over GPRS (or the verizon equivalent). Sounds suspiciously like SMTP on the computer, which is over TCP/IP, which happens to be over ATM (for DSL).
Cellphones for the last ten years or so have used "real" internet - no translation required. With real IP addresses and everything (though they may be NATted).
Not Linux. Randomness comes from the time (hardware, persistent), but also from the randomness of network traffic and other driver miscellanea such as HDD head seek times, mouse movements, keystrokes, CPU temperature data, electrical noise on the power supply (with the right hardware)...
I can't say for sure, but I think Linux actually has the most secure random-number generator of any OS - excluding dedicated hardware. Enough that it can probably be fairly called true RNG instead for PRNG, as long as you use/dev/random instead of urandom.

Yes, I said that in my post. It's not hiding:
Other appliances, generally those with electric heating elements (such as a range, water heater, furnace, machines such as a tablesaw) run off dedicated 220V circuits.
Every appliance you mention, with the exception of the washer (which receives hot water from the water heater) runs on 220V in the US.
Hah! With a UK socket, you can't do that!
UK 1 : Everybody else 0

Yes, in hand-written assembler.
No. All of AT&T is EDGE. From Wikipedia:

So when you write your own code, you've written a CMS. But you just passed one up because it was too heavy-weight...
I'm not him, but I needed - more accurately, needed proof of having taken - a shitload. Here's the list:
Hep B, Measles, Meningococcal, Mumps, Pertussis, Rubella, Tetanus-Diptheria, Tuberculosis, Varicella
I needed to fax in proof that I'd either had the vaccine or been infected (chicken pox aka varicella)
