You can make the same points on resiliency for the Internet. The question is, is it worth continuing to maintain POTS, and if not, should we extend the resiliency of the Internet within smaller regions.
I just tested my year-old Panasonic microwave: it uses 2W in standby. Interestingly, it uses 22VA, because the power factor is a horrid 0.12, but still the true power is only 2W which is pretty small, and probably normal for an appliance like that.
I was suspicious about that myself, and searched for answers: I think my power meter measures only apparent power, not actual power.
Do you know if the low power factor is because of the unusual (compared to everything else I own) power supply required for producing microwaves, or is it just cheap?
Paper tickets, particularly annual ones, could wear out, which usually meant a long queue. If an Oyster card fails (or is lost) you can transfer the balance / passes to a new card online. (I've done this a couple of times with dropped, unregistered cards I've found, back when I used to change buses in central London at night regularly.)
I've just logged in to the online Oyster system, and I can buy annual season tickets.
Cheap Bus fares? Hardly its £5 for a 3 mile trip were I Live and before you ask there are health reasons I cant walk / cycle / car it.
For comparison, it's £1.35 for a single bus (or tram) journey of any length in London, day or night.
I had read the bus network actually makes a profit, but I can't find the report. The Tube is expected to make a profit next year -- maybe that subsidy isn't as big as you think.
London's system was introduced over 10 years ago. - It reduced fare evasion, which existed due to limitations of the previous paper ticket system, - It made working out the fare system optional -- they guaranteed it charged the optimal fare - It made boarding buses in particular much faster, as it significantly reduced the number of people paying by cash (which was made expensive) - It gives much better detail on demand for routes, how long journeys take, etc, so it helps transport planning - It's reduced the number of people needing ticket offices, and the latest proposal is to close most of them (staff are to be in the station, and would help a passenger use a ticket machine instead). - It's led to the acceptance of contactless credit cards, which isn't yet finished or widespread, but should be more convenient for infrequent users (will the new Chicago system accept these?)
I don't think I get as much exercise as I should, and I cycle 13km every working day, my flat and office are both on second floors but I don't use the lifts, and I don't own a car so all trips not cycled are by public transport. Also, it's at least 500m from the office to the usual place for lunch. (I'm skinny, but I'm still in my 20s and doubt sitting for most of the day and many evenings does me any good.)
I've been considering going swimming at lunchtimes, but haven't yet made the time to do so.
Partly, as I was thinking of my own computer: I turn the switch on the mains power socket off (i.e. state G3, Mechanical Off) when I'm not using the computer.
I don't have any boxes for the TV. The cheap DVD player has an actual off-switch on the front.
Assume a computer uses 3W standby, 150W powered, is used for 8 hours a day, and takes 6 minutes to boot up and shut down.
Leaving it on consumes 150W*8h + 3W*16h = 1.248kWh Switching it off consumes 150W*8.1h = 1.215kWh
You need roughly 500W power consumption for it to break even, or a 20-minute start up time.
My home desktop is used for about 16h/week, according to the log, so it's definitely worth switching off. It's almost five years old, so that could make the standby power higher.
It could also be the power meter giving a false reading, which I think is likely. I read about it earlier today, apparently it cheap and doesn't / can't measure the power factor, and the microwave probably uses about 3W in reality.
Hasn't Thanksgiving just got tangled up in the currently-fashionable religion? It's a harvest festival, which in Europe pre-dates Christianity, and exists in other cultures with a clear harvesting time.
The British version is equally for friends as family. I've missed it for the past three years due to foreign travel, but I used to celebrate with friends (i.e. drink too much).
the holiday is known for overeating of food and buying too many presents. sigh
You could say exactly the same about Christmas in the UK. We even choose turkey!
There will be more surveys like this in the next few weeks: "Only 10% of adults across the UK think that its religious meaning is the most important thing about Christmas" "just 4% of 25-34 year olds compared to 20% of those over 60, gave the religious connotations of Christmas a top rating" "86% of those polled agree that Christmas has become too commercialised"
However, "The YouGov Spending intentions survey for 2013 found that people are planning to spend on average £822 celebrating Christmas. The individual spending figures Are: £599 on presents, £180 on food and drink and £43 on cards, decorations and Christmas trees." (this survey). Looks like I'll be about £500, £160 and £43 behind the curve.
I prefer to keep work and personal life as segregated as possible, I kinda assumed most other folks did too?
About a month ago, I stuck a job advert on Facebook. I'd meant it for friends-of-friends, siblings-of-friends, etc, but that weekend, the girlfriend of one of my closest friend's told me she was encouraging him to apply. I said I'd be a bit uncomfortable if he did, since if he got the job I would have been his manager. (He didn't apply.)
However, two of my colleagues in IT have spouses in other departments.
Why is this still a problem. Why can't the publisher's do a special run of their text books for Texas that includes whatever rubbish Texas wants, and then provide decent text books for everyone else?
Because its cheaper to just create a book that includes all the rubbish Texas wants and force everyone else to buy it, too.
Why does everyone else settle for this? Depending on the numbers, the Texan book or the 'normal' book might cost a little more, but both sides should be willing to pay for it.
(And is there only one publisher? What's stopping another publisher making a book without all the religious crap?)
I only have 2500 emails in my Exchange inbox, but found Outlook was struggling -- possibly we have an old version, I'm not sure.
I like Thunderbird's Full Text Search, and now use Thunderbird for 95% of the emails I send. It has a threaded email view, a bit like GMail, which I also prefer. I still use Outlook (or my phone) for my calendar.
I don't know how it would cope with 10,000s of emails. The initial import would take a while.
Ah, that probably explains why Outlook at work hangs for two minutes after I load it. Thank you! I had installed Thunderbird in frustration (which is better than the version of Outlook we use, it has instant full-text search) and was using my phone for managing appointments.
Kolab and the associated KDE clients are decent, but it's been a long time since I tried them out properly. I hadn't heard of Zimbra. (This stuff is not my area at all.)
I use Thunderbird (unofficially) at work. It has instant full-text searching through all emails, and a great search interface. It's impressed a few colleagues, who are all using Outlook.
When I installed it, I expected nothing to have changed since I'd last used it properly, in about 2008, and was pleasantly surprised.
My Sony compact audio system uses about 30W while off. My cable box uses about 20, with 10% more if it's on.
Wow, that's a huge amount! My electricity supplier sent me a watt-meter because the government required them to do things to reduce consumption. Almost all appliances use only 1-2W if left on standby, the exceptions are the Wii (15W), the microwave (a massive 50W) and the desktop computers (5-10W).
We unplug/switch off at the mains* the Wii and microwave, which are rarely used anyway, and I switch off my own computer. Together this will saves about £80 over a year (65W * 1 year = 560kWh at £0.13/kWh, yet annual usage for the last 12 months was 2600kWh).
I cycle 5.6km to work, but don't need time to cool down or change clothes. It's not a race! It takes a bit under half an hour.
(Except sometimes on the way home, when I feel like going as fast as I can.)
I can't solve winter for you, and it's not unlikely that your summer is hotter than mine. I might see ~3cm of snow, in which case I'll either take the bus (~40m), or, if all the car drivers have been scared away from the roads again, cycle down the main road, which will be nicely gritted and salted.
It would be interesting to compare America (and Japan) to elsewhere, where 230V is the normal voltage. I don't know how much power you can draw in other countries, but in the UK it's 3000W (13A at 230V), and off-the-shelf appliances exist that have this power draw (electric room heaters, kettles).
The electric grid would probably require improvements if the load pattern changed with lots of EVs, but for an individual buying a car now, powering it should be much simpler.
Says a man who has obviously never take a bus from Minneapolis to St. Louis -- 18 hours over 3 buses, sitting shoulder-to-shoulder the whole way with no more freedom to move around than you'd have in a plane.
And that's not even a long bus trip.
That is a very, very long bus trip by the standards of almost all the world.
A short bus trip is the one I'm late for: 12 minutes to get to work.
The longest trip I've ever made by bus was about 10 hours.
To drive (or take the bus) to work, I would make three turns. I could cycle the same route (it's not forbidden), but there is a more direct route which avoids the unpleasant, busy roads. That involves 13 turns. I have another route, which is a little further but nicer (along the river for half the distance) and that's 10 turns. When I first moved here, I studied a map and set off early to give myself time to find the route, checking on my phone where necessary.
If I regularly wanted to cycle in unfamiliar places, but didn't want to follow the easy routes -- the big roads full of cars -- I'd be interested in a better GPS.

Really, why do we think that POTS would continue if we were partitioned or that data lines were taken down?
Because POTS will work in some of the worst environmental conditions possible. It survived the nuclear bomb attacks on Hiroshima and Nagasaki

Marklogic, afaik, is the only acid compliant nosql solution that exists.
Neo4j is an ACID-compliant graph database (so it's NoSQL, but that word is a bit pointless).
It's also the most useful non-relational DBMS: relationships become first-order entities, having a type and properties.

London Underground toilet map (not so great in the centre, but pretty good elsewhere).
They're in probably half of European underground stations, on average. Expect to pay 0-50c, depending on the country.
My local station (in London) has one, it's always very clean. I don't think many people use it.

Define "push bike"; I don't know what you are talking about.

No, they're called balance bikes.
Because, to pick a random bit of North Carolina: http://opencyclemap.org/?zoom=16&lat=35.80116&lon=-78.64709&layers=B000 the route a cyclist follows is often more complicated than that for a car driver.
