240V would be used for kitchen stove/range, clothes drier, electrical heat (air and water). Some commercial cappucino machines use 240V.

A home shop could very well use 240V for a welder and any number of power tools...lathe, jointer, planer, tablesaw, mortiser, wide belt sander, dust collector, shaper, etc.

Comment: it's 240V in USA/Canada (Score 4, Informative) 258

In the USA/Canada typical residential setups use two conductors at 120V to ground, but the conductors are out-of-phase so there is 240V between them.

There really isn't any such thing as 110V or 230V in the USA/Canada, both of which you'll sometimes see referenced. 208V does exist, it's the difference between two legs of a 3-phase setup where each leg is at 120V to ground.

If it were all about "even" traffic flows, then netflix could have their clients send garbage data back to balance out the flows. This would result in *more* traffic on the network overall, but hey it'd at least be balanced!

No...the traffic is there because it was *requested by verizon's subscribers*. There is no logical reason why cogent/level3 should pay extra for traffic requested by verizon. I know this is how it was done in the past, but that was under the assumption that the types of flow is more or less similar. In the case of verizon, it's mostly consuming data rather than sending it, so it shouldn't be treated as a regular peer.

caveat: I live in Canada, your mileage may vary.

When I see a person panhandling on the street, I know full well that there are social assistance programs, welfare, employment insurance, homeless shelters, retraining programs, health care programs, etc. In many cases, they have trained professionals who will probably do a much better job than me of helping people that need help. In a sense that means that *I have already helped them* by supporting a society and government that includes these programs, and by funding them with my tax dollars. In many cases the problem is just getting people into programs that will work for them.

That said, I still help people out sometimes if I think it makes sense. Most of the time though my charitable giving goes outside the country to places with less of a social safety net.

It seems to me that we want to simultaneously be able to prove to the voter that their vote was counted properly, while also wanting to ensure that the voter cannot prove to someone else that they voted a certain way (to prevent buying/coercing votes).

Adding to this...how do you ensure that the person voting is who they say they are, and not another family member, care provider, guest, etc.?

Again is it okay for the government to compete with private enterprise?

Others may disagree, but I think so, yes. (Assuming they compete on merits rather than legislation.)

Around here (Saskatchewan, Canada) the main telco is a government-owned and they have excellent wireless coverage in rural areas. My electricity comes from a government-owned utility, and their rates are controlled to cover costs and build infrastructure. My natural gas comes from a government-owned utility that has huge underground storage tanks all over the province so they can buy gas at low prices and store it for winter. (Important, winters are cold here.) The main vehicle insurer is government-owned with controlled rates, and of course police/fire services are government-run.

The only real complaint I have with a government-run organization is liquor stores--and that's a political issue since there's nothing stopping them from implementing a solution where I could order booze via a website and have it shipped to my house with the appropriate taxes automatically paid to the government.

Being able to put feet down requires a more upright and open riding position.

Removing that requirement enables a recumbant seating position (for better aerodynamics) and a fully-enclosed cabin. Making the cabin fully-enclosed allows for better protection from weather, better soundproofing, air conditioning, etc.

Some really intricate parts are cheaper to 3D-print than to try and cast/forge/machine traditionally. Think hollow structures with stiffening ribs or cooling channels inside, or other similarly complicated shapes. The SuperDraco rocket engine falls into this category (though of course also is a small production run).

With managed hosting, the provider handles support, backup/restore, etc. Typically with "the cloud" the resources are unmanaged. The end-user is responsible for all of that stuff.

I don't believe Amazon themselves offer managed services, but there are lots of other companies that will sell you managed services built on AWS.

Nobody is saying they were legally responsible to prevent crime.

Even for VoLTE, why should your voice get priority over my data? What if my "data" is actually voice via a different app?

Arguably, all packets should be shaped initially based on the subscription plans of the subscribers without regard for data type. Then *within the packet stream of an individual subscriber* they could prioritize based on traffic type, but it should be up to the subscriber to indicate whether they want this to be done, what should be prioritized, etc.

1) It's not about how much you eat, but how much your body converts to fat. I went on Atkins and lost quite a bit of weight while still eating lots of calories.

2) If you severely cut down on calories, your body can become more efficient at using the calories it does eat.

So the trick is to convince your body that it's not hungry, doesn't need to be efficient, and doesn't need to store fat against future needs.
