You should also add that around 100 nuclear power plants (in the US) have to survive such an event. If they are not going to survive it then you have to prevent your opponent from taking over your country or provide some credible deterrent while you have not sunken into chaos yet, i.e. with some nuclear assault.
I have strong doubts that anybody openly just starts an EMP attack and then does nothing (apart from the sun), I would rather expect this to happen after some conventional warfare has not yielded results and a nuclear attack is next on the list (the one out of Kahns book).
Given that previous high altitude tests all used fairly large yields in the 100kt to Mt range I would doubt that terrorists would be able to pull this of credibly. Assuming some conventional conflict is already taking place I would think that the countries involved would have some time to prepare for nuclear escalation. Also there is some chance that your economy will have tanked some time before hostilities break out, just because the global economy might have fallen apart that provides access to foreign resources. So from that end I would rather expect some slide into disaster instead of some catastrophic event.
Actually I would rather worry about net energy decline and climate change since those issues will kill more people with greater certainty and in agonizingly slow motion.
Not just that, also note the scale at which western societies are not farming societies anymore. In my neck of the woods we have 2% aging farmers that are on average 40 years old. Comparing that with Thailand's 50% I would expect quite a bit of restructuring to be necessary if we were ever to return to a farming society, not to mention the event of some catastrophic decline.
The twenty minutes will turn into a few hours when people have to walk out of the traffic jam. This might give you some time to flee. For the shits and grins I actually tried the walking part for my particular city and the 20minutes turned into 2-3 hours. It was an incredibly pleasant day for the hike, but my feet hurt like hell afterward due to inappropriate footwear (sandals).
But no, temperature recordings normally start mid 19th century, that is tardy. Now if they had actually started doing something against climate change around 1950
You could also set up some kind of DMZ where you use a router with firewalling capabilities between broadband and your home network. This gives you some security now while you are still experimenting. Also it is a good idea to not trust your router and set up your own firewall in addition to it. Beyond that you may also protect us from your experiments that way.
I don't think that the type of system is important to our standard of living, energy input on the other hand appears crucial however. The type of system develops with the energy input available, I doubt that we could have a much different system from what we have.
"At the heart of England’s idea is the second law of thermodynamics, also known as the law of increasing entropy or the “arrow of time.”"
This is great, now somebody can easily go and model the economy thermodynamically. After all this should be a much simpler system.
Then again thinking about the second law feels like you can never come out ahead, introducing this concept to economics would be fatal to certain parts of the finance industry.
At the time I switched to Linux I had only DOS which I regarded as inferior due to MS not supporting a flat memory model. MS started to support this in a credible way only with winnt in 1993, whereas they could have had something when the 386 came out in 1985. Given that they started in 1981 they had only four years of acquired customers but they managed somehow to respond to new hardware with a delay of eight years.
Once I had Linux running in '95 I also totally liked the grown up look X-Window had. Maybe you should tell your kids "... and when you grow up I'll let you play with the big iron".
No, I wanted to joke about somebody being wrong on the internet. Also if you have risen to her position as a PR person you know that you don't say the thing she said. According to Pareto 80% of all people are stupid, so...

There is a clear potential for her being wrong about whiteness causing rational behaviour or something similar. While some might argue that often it is just easier to shut up, she could have rather said something like "I let the guys use condoms".
Given that the corn ethanol EROI is so bad, and most people seem to know, I'm kinda wondering who would be desperate enough to try it anyway. The problem is definitely not laughable however.
You do have a point but there are other effects, like totally forgetting that through specialization we have become dependent on each other. Here is an example:
I wouldn't call my latex experience efficient by default, instead I call the result pretty and this is all that count's. Also it gives your resume a certain well recognized format, at least by the people in the same club. Why would you deal with Winword noobs.
Oh right, I meant to say tablet. Tablets support serial usb devices, and serial USB ports can be pretty fast too. You still need a PC to program the thing unless you can get openocd to work on your tablet.
You can build one yourself. Assume the BeBox geek port:
One "GeekPort" (37-pin D-shell)
An experimental-electronic-development oriented port, backed by three fuses on the mainboard.
Digital and analog I/O and DC power connector, 37-pin connector on the ISA bus.
Two independent, bidirectional 8-bit ports
Four A/D pins routing to a 12-bit A/D converter
Four D/A pins connected to an independent 8-bit D/A converter
Two signal ground reference pins
Eleven power and ground pins:
Two at +5 V, one at +12 V, one at -12 V, seven ground pins.
It even has a User USB port, you can use. Then you have to invest some time implementing the whole communication chain to your PC. ST generally has a standard peripheral driver library that can help you with all the stuff you can do with the chip in question.
Apart from the powersupply stuff the bebox offers, you will find everything else and more in the microcontroller. If you want to build an external geekbox you would want to add a separate power supply. Then you could use the microcontrollers PWM outputs to regulate some voltages for a power supply output, or use some dc/dc converters for fixed voltages.
From the top of my head I wouldn't know what to do with it though, but I do need a power supply unit, some measurement means, and some stimulation means for circuits.
Personally I blame stupid women and needy men on this, all sensible and industrial needs are fulfilled with artificial diamonds. The problem is diamonds are not really the issue we are talking about. It is first and foremost energy and concentration of minerals and their availability. If the concentration of ores in unstable regions lowers enough that stable regions are becoming competitive again (hmm, why would that be?) things will change.

They could have thought about a study like this when they first started thinking about the green house effect and climate change:

This gives you some security now while you are still experimenting. Also it is a good idea to not trust your router and set up your own firewall in addition to it.

You can also try to scan/hack your internal firewall with tools like nmap to see how it is holding up. Here is a list of a few links:

Also there is user friendly in case you have been missing it so far, http://ars.userfriendly.org/ca...
About the same as from 1950 to 1975?

Mostly, but he was talking about food, and that in our part of the world needs 10x the Joules for production of the amount it eventually contains.
First the ~5000 pages of i.mx53 documentation and now this! This is pure and unadulterated terrorism I tell you.

There is this article I remember about British women increasing the chance of getting HIV by having unprotected sex in Africa:

It doesn't always work either. I totally remember when I accidentally grabbed that 220V mains line 20 years ago.

Given that the corn ethanol EROI is so bad, and most people seem to know, I'm kinda wondering who would be desperate enough to try it anyway. The problem is definitely not laughable however.
Not to forget that the US tried that with the prohibition and it didn't work out either.
Students still have too much time on their hands.

My current favourite are STM32 discovery boards, i.e.:

(costs $10)
