Over the time scale of the next century, only one input signal will dominate: the amount of added greenhouse gases. All of that other stuff either oscillates too fast or has an insignificant effect. Other signals that would have a big impact, such as changes in the earth's orbit that drive ice ages, or movement of mountain ranges due to continental drift, are too slow to have an impact over the next couple of centuries.

Relative to the greenhouse gas signal, the climate *was* very close to an equilibrium on a human timescale. It certainly isn't any longer; it's being strongly driven into ranges hotter than it's been for millions of years.

The final color of mixing two buckets of paint is the integrated effect of chaotic stirring (and all of the world's supercomputers probably couldn't predict the exact pattern of those swirls). However, the final color can easily be calculated with high precision using a hand calculator. Integration has smaller error bars than you think it does.

That is because you assume that "Apps" are the same as "Applications" or "Programs". That isn't really the case: "Apps" come from the mobile space and are usually touch optimized dumbed down versions. Often they are just fronts for web applications, instead of full native applications. Applications or programs like Thunderbird are not "Apps", they stand on their own and talk SMTP and IMAP and are compatible with all servers that speak these open protocols. That is inherently superior than proprietary "Apps" that do not talk open protocols.

So ironically, transporting the oil and gas out of the region is putting oil and gas production in jeopardy.

That would seem to be yet another reason to transition this country away from fossil fuels altogether. That would address both the erosion issue and the fossil fuel dependence at the same time.

As far as seafood goes, there's going to be a coastline somewhere, no matter how far it moves into the current state of Louisiana. The seafood will still come from wherever that is.

Doesn't work that way.

*of course* it doesn't... That's was the whole point of the thought experiment.

They may store a copy of the account balance on the card. This is only for your convenience - so the card can report "out of money" and reject the offline transaction.

That would be a reasonable assumption. I wouldn't count on it... Overdraft fees are the bread and butter of banks ;-)

Last time I was in Val Thorens (basically the highest ski resort in France, maybe Europe), I could use my cellphone everywhere... including Internet. Hell, the *first* time I went there, I surfed on the internet using my Psion Revo connection using IR to my Siemens 35i using GRPS. Given the hardware, you can basically guess when exactly that was.

Besides, all it needs is a phone line.: Classic POTS for the terminal base to be connected (the handsets can be wirelessly connected to it), and if those people had a phone, they had a connection.

From my understanding, in Europe, the chip and pin does make a connection. Terminals generally do have a connection. For a while a lot of them were GPRS or POTS, so you can guess how long this has been used. I remember a few restaurants that had horrible cell reception, and you were pretty much asked to come chip and pin at the counter where reception was acceptable.

I do think that below a certain threshold amount, making the connection isn't mandatory. That's usually when it goes quickly and it doesn't say "connecting". I've only seen it happen on small amounts. Do note, that this is what I conclude from the behaviour. It would be better if someone who actually knows how this works to chime in.

If anything, I do not think that it's the card that stores the transaction. It would not make any sense at all. Imagine I do a 1000€ purchase, and it would be store-on-card. At that point, I destroy the card or never use it again. My card never gets the chance to "synchronize" with anything. Now, perhaps I misunderstood what you meant with "the balance would be kept on the card", but it definitely doesn't involve storing anything on the card. It's the terminal that must store and forward the transaction. Granted, it doesn't change anything in your scenario, but given European chip 'n pin do connect, I doubt you attack would be feasible (ignoring the fact you need a 1000 unconnected terminals, which is doing to be very hard to find).

Don't diss old Thinkpads. I got myself a Thinkpad X220 (Intel Sandy Bridge) for 179EUR recently and given the form factor (12") and the fact you can slap in 16GB RAM (99EUR) and a SSD suiting your needs (I went for 128GB, I don't need much - 49EUR), I have kick ass machine for 327EUR total. It even still has 85% of battery capacity left. Getting replacement batteries is no problem for Thinkpads, but right now this is sufficient.

That's netbook prices, for mid-level laptop (typically 15") performance. Granted... Pre-owned, but we are talking about recycling.

It comes with a 7 license, I upgraded it to 10 with the "assistive technologies" upgrade and now I can choose to run 7 or 10 on it... This is mainly for the day, I want to pass it on to a new user. I simply run Linux on it and everything works out of the box.

Granted, I have no idea what I'd do with 10 of them and a new MacBook sure would be nice... but for the thrifty, I'd suggest getting a Thinkpad any time

I am still using my iPhone 5. It's on it's third battery though, and the current one is (again) bulging. I need to find a better battery supplier.

What I do think, is that upon the next iOS refresh, they'll go full 64-bit and then the iPhone 5 will be out.

At that point I might get my wifes old iPhone 6 (She always gets the newest, I take her old one), but I really prefer the iPhone 5 form factor. I might splurge one an SE instead.
