My concern is that every device we have whether general purpose, dedicated, specialized, COTS, or whatever has had more and more microcontrollers built in over the last 20 years, sometimes dependent on inputs you may not even be aware of. Many applications use GPS signals for timing, for example, whether or not they use GPS location data. Electric power dispatch centers used to maintain their own atomic clocks - now only the very largest do while the rest depend on GPS timing signals. And those types of dependencies are not always obvious. You might break out the sextant and figure out where you are only to find out the fuel pump speed controller won't turn on because it was using GPS timing signals as a reference.
The damage that the Bush/Cheney Administration did to the United States will continue giving for at least the next 50 years, which is why many voters will choose any non-Radical-Right candidate no matter how flawed over the return of the Cheney/Rumsfeld/Yoo/Addington/Bolton set.

Strangely this was not a problem for the hard Radical Right when Karl Rove created the same setup for the Bush Administration (probably a violation of the Federal Records Act for a President and his White House advisors) and then ordered the backup tapes destroyed when it was discovered (definitely a violation of multiple federal laws and regulations).

We could start with some evidence that tech per se is necessary to or improves education [*]. Education methods developed around 600 BC (if not borrowed from earlier times) have been pretty successful across many times, places, and cultures in the 2600 years since; post-1970 "electronic learning" beginning with PLATO has not proven very successful, or even at all. Oddly however the "metrics" so beloved of "reformers" today doesn't seem to apply to technology-based education attempts.

Walker flat out lied about anti-Walker protesters damaging the state capital building. Not only did the protesters do _less_ damage than any other group that size that had used the capital grounds (as documented by the building & ground dept) but they brought trash bags and cleaned up the area afterwards. Walker repeated released utterly false and fabricated statements to the opposite. That tells you all you need to know about him, although the phone call where he talked to the radio DJ he thought was a Koch brothers operative was pretty telling as well.
On the scientific side the "house kept too clean" theory is interesting but by no means proven. Northwest Scotland is considered to have the cleanest environment in the developed world (due to wind and rain from the Atlantic) and that was true before 1970 as well but children there have seen the same increase in nut allergies as elsewhere.
On the human/interpersonal side the use of the word "coddle" points right back to the "illness as moral weakness" syndrome that a large percentage of the human race seems to suffer from.
That is a very good question. The incidence of severe food allergy, particularly but not limited to nut allergies, is documented as having risen sharply throughout the Western world since 1970. So your impression that there are more severely allergic food people today (not just children as the numbers were high in the 1990s) is correct. What the source of that increase is is not known despite a fairly large amount of medical research. The "houses kept too clean" theory is interesting but by no means proven; northwest Scotland is considered to have the cleanest environment in the developed world (due to wind and rain from the Atlantic) and that was true before 1970 as well but children there have seen the same increase in nut allergies as elsewhere.
There is a also the third factor: where people who do not have life-threatening allergies, particularly life-threatening allergies to nuts, develop an attitude that (1) such immune system allergies really don't exist (2) those who claim they do, or who experience anaphylactic reactions to foodstuffs are (a) lying (b) morally weak.
I've seen people with that attitude try to push peanut butter cupcakes on 3-year-olds with severe peanut allergies. Oddly they are never very happy to be educated on their ignorance or its source, their attitude.

If you and your political party are going to classify Social Security as "welfare" rather than (a) a decent thing for an extremely wealthy society to do (b) an incredibly successful program of alleviating poverty among the elderly (c) a good method of moving people through the employment system and opening slots at the top so young people can get jobs at the bottom (d) one of a basket of preventative measures against a communist revolution [as envisioned by that flaming liberal Bismark and used by Roosevelt and Hopkins for the same purpose] then you are welcome to do so.
However, if you and your political ilk want do do that you need to stand up and say so explicitly to the entire nation. Including not shirking from explaining to the heroic {yeoman farmers} ranchers of the suburban/exurban range that they too are taking "welfare" when they apply for "their" Social Security. To date the hard Radical Right has been successful in using half-truths and dog whistles to imply that they will somehow manage to chop Social Security for the "undeserving" while leaving it in place for the "deserving".

= = = http://krugman.blogs.nytimes.c... But I think it’s also important to understand where this is coming from. Partly it’s Bush trying to defend his foolish 4 percent growth claim; but it’s also, I’m almost certain, coming out of the “nation of takers” dogma that completely dominates America’s right wing.
At my adventure in Las Vegas, one of the questions posed by the moderator was, if I remember it correctly, “What would you do about America’s growing underclass living off welfare?” When I said that the premise was wrong, that this isn’t actually happening, there was general incredulity — this is part of what the right knows is happening. When Jeb Bush — who is a known admirer of Charles Murray — talks about more hours, he’s probably thinking largely about getting the bums on welfare out there working.
As I asked a few months ago, where are these welfare programs people are supposedly living off? TANF is tiny; what’s left are EITC, food stamps, and unemployment benefits. Spending on food stamps and UI soared during the slump, but came down quickly; overall spending on “income security” has shown no trend at all as a share of GDP, with all the supposed growth in means-tested programs coming from Medicaid: [graphs follow] = = =

Was the design spec "get payload to correct orbit safely" or was it "get payload to orbit with zero subsystem failures"? Maybe there was a reason the designers chose to use five smaller engines and an control system that could compensate for the loss of one or two.
The "welfare" programs that were in place from 1934-1996 no long exist, but even taking the succeeding limited programs under as successors "welfare" has been cut continuously from 1981 through to this day, including during the Obama Administration. Not sure where this breitbart myth of the luxurious "welfare" benefit and the t-bone steaks comes from but it has no basis in factual reality where PRWORA was passed in 1996 representing the ultimate capitulation of the neoliberals to Reaganism.

Consider the financial system meltdown in 2008. From 1990-2007 the large financial entities took trillions of dollars of profit for themselves. Part of the deal of capitalism is that when you have profit opportunities that big you willingly accept the concomitant risk including the possibility that should the risk actualize you will go broke and might go to jail. The risk actualized. The USG stepped in (along with the EU and UK), paid off the losses, and did not require the financial services firm and their executives to take any penalty at all; instead the government passed the cost on to the median taxpayer (43k/year income). That is allowing a supposedly capitalist/free enterprise to privatize profits (i.e. squeeze them out of the polity) while socializing risk (paying off huge private losses with tax money).
