W/ regard to space-based and airborne systems (commercial jets also actually operate in a fairly high radiation environment): The risk of faults is not only non-zero, it's expected. Google 'single event upset' and '

This is exactly what you do -- lots of spares. If you're big enough, and have a big enough need, you can also design you own hardware ... although even that has limits, since foundries do eventually retire process nodes.

Dead wrong. In sectors that are in a safety critical or mission critical environment, it's not at all unusual to see systems that are decades out of date. We just recently retired the last of our VAX machines, and we still run a large

Also, replace mentally replace every instance of "museum ready" in this article with "mission critical" (which most of them probably are), and it'll seem a lot less ridiculous that they maintain them.

If you're ever back in Michigan, you should visit the west side ... and also check out lake Michigan. Grand Rapids isn't as big as Detroit, but our economy is growing at a healthy clip and there's a lot of interesting things

With you all the way. I have 11 acres, horses, a goat, cats, a dog, and I live 15 minutes from downtown and 17 minutes from work. This is in a mid-sized midwest city (Grand Rapids, MI). While I realize that I could achieve a substantial pay

One thing the author totally overlooked - when you have a large percentage of the population that spends an extra 2-6+ years in education, that same large percentage of the population spends 2-6+ less years producing things for people to co

Disagree with agriculture being a disaster everywhere. Here in the midwest (Michigan, in my case) we get so much rain that there's rarely, if ever a need to artificially irrigate. Personally, the land that my horse pastures are on is s

I wonder what kind of bandwidth they're getting with their car (suv?) full of servers. More seriously, though, wouldn't something like camelcamelcamel be a perfect candidate for AWS or something similar, thereby preventing headach

Ugh. 'Infinite' vacation policies are starting to infect corporaculture. I work for a megacorp (that I actually rather enjoy working for) that recently went this way, and since my megacorp is a bit of a trend setter, you can expec

Compressed air storage is only as efficient as the insulation on the storage reservoir. Without insulation, the heat generated by the compression process is lost, and much of the stored energy goes along with it. This drives up the cost of

I teach CS classes at a community college when I have the time. Our CC has a 2 year program; having taught classes in the 1st semester and the 4th semester, I have noticed that the 1st semester classes are larger than the 4th semester class

Oh, we still do, they're just in second and third world countries. The author of this article focused on service industries that require a physical presence in the local area ... and did not address outsourcing. I think that one likely

Fascinating article, but it was hard for me to get past 'Immune defence'. I'm sure they meant no offence, but it coloured the rest of the text for me. (If it had been on a .co.uk, I'd have left them alone, scout's h

I taught that class once. It does have some prerequisites, but not a ton. I think it could be taken as early as second year, first semester at that particular school.

Windows before 30 years of updates that were created with a need to maintain backwards compatibility feels so cohesive. I mean, that control panel is just so clean . Also, would be interested in seeing the orginal Win 95 (before OSR2). It

I didn't personally downvote you, but I'll give you my best guesses: 1) The percentage of die used for decoding is actually already quite low. Per Anandtech 2014, it was at 10% for x86 and decreasing: http://www.anandte

I see. Many of the countries you listed are actually 'workfare' systems, as this article proposes, and not true 'welfare' systems. Canada - much of the 'welfare' is paid by the province, not the federal governm

I'd take a few of countries that you think are good examples, why, and their median PPP household income and/or examples of the life of a typical person. For example, here are some negative examples: - USSR: The USSR had a central
