I work in the auto payment insdustry. The number of errors are small but they do exist. Sometimes someone submits the same batch twice or the account numbers get converted into floating point and back.
Remember that if you give a company your credit card number and they screw up, they take a banks money. If they screw up with direct debt, they take your money.
I have experimental data that shows your numbers do not apply to the box of some 30 or so different types of light bulbs I have tested. CFLs should be better but some of them are worse than the incandescent they are supposed to replace based purely on light output per amount of energy.
Does being object-oriented help? I look at the quality of the code written in C and I look at the quality of code the comes from pseudo OO languages (C++, Python, C#) and it is not up to the same standard. It seems to me that OOD hasn't help up to the ease of use that its proponents have been pushing for the last few decades since it seems to lure developers into a false sense of architecture scale.
The + type addressing was used in some of the non-uucp and non-smtp mailers that were common before 1991. It was sometimes used to relay virtual user or host names to hosts through nasty uucp (!) paths and smtp later % based relay paths. Just about any symbol that wasn't nailed down got used for something and that often varied in incompatible ways. I seem to remember something on a 3081 or other real big iron that used and address of the form group+user so you could get user mail but others in the group could check on it but that might have been a different symbol.
I like the required restroom signs. Nearly every sign in the developed world uses a triangular dress shape for the ladies yet California goes and requires the men's signs to be a one foot equilateral triangle and the women's to be round. Why did they pick the symbols that way? Was it an cruel inside joke for the visual impaired? Were would I find reference to how this was developed?
My box of bulbs consist of a sampling of one of each type sold at the local K-mart, grocery stores and a few specialist bulbs. I agree its a poor box of CFLs but it represents what people are using. Some of the 11W Ikea bulbs produce light on par with a 25 Watt incandescent. The problems is the Ikea bulb has a power factor of about 20% and takes 17W at the bulb so the energy required at the substation is higher than the energy required to light up the 25W bulb which only takes 20W. That doesn't take into account the fact that CFL typically only produce 80% of their new light output after 1000 to 2000 hours. There are a few CFL that are a bit more efficient than plain old bulbs but that is only if you don't consider their manufacturing energy. The most efficient bulbs I've found so far are the LED lamps followed by the halogens. My test doesn't include the luminaries (aka light fixture) but there are designs that do work better for some types of lamps. I also have one CFL that is producing a massive amount of ozone and I don't know how common that is.
The cost of a disposable bag is US$.015 if you only order 1000 according to google. Your grocery store pays far less than that is may be closer to about.004 for a typical non chain store that won't buy them by the pallet. The $1.50 bag you bought was very likely subsidised (I can't find them at that price with google) and might be better made than most of the current offerings.
The point is the bag you buy for $1 at the super market so they don't give you a free bag took far more resources than it will ever save. The ones I've looked at here include at least 7 different types of plastic. They weight about 100 times what the older bags weigh. Based only on the mass of oil needed to make the new bags, they had better last more than 100 uses to be more environmentally friendly. The mix of plasics make the new bags completely non-recyclable and they will last just as long in the landfill and even longer in a river, lake, ocean or roadside. The floating rubbish traps in the Yarra River in Melbourne are now collecting a large number of the "green" bags but I haven't seen any good stats yet on the counts of them vs the older style.
40 bit DES is already in the realm of home machines. The problem isn't trying all the 2^40 key combinations but detecting when one of them gives you the right key. If you know the plain text is most likly ASCII, then you can check that the top bits of a block are all zeros but then you still have to have another way to process the 2^32 results that pass the 1st test. The more you know about the plain text the more false results you can discard but there still may be loads of other keys that might look right until you get to the next block depending on the chaining method.
The temperature data is fact. Is the temperature data fact or fiction? I'm seeing more evidence that more and more of it fits into the fiction category. A few points as examples... most weather stations in the developed world are in local heat islands where there is more traffic near by. Many sites that used to be in fields a decade ago are now have cars idling next to them for many hours a day waiting for stop lights that didn't exist just a few years ago. There seems to be some indications that smarter traffic control in Texas is dropping the local temperatures. Another bit is the space based systems that weren't calibrated to the previous system. Each generation of system measures slightly differently and they are all calibrated so the lines are smooth and reflect what is going on at a specific spot yet if any of input variables used to calibrate it are shifted to the other end of the reasonable range, the results are much different.
The religious issue is getting stronger and the facts seem to become less important over time or are just discarded outright. We here CFL are up to 80% more efficient yet I haven't seen one yet that is more than 50% and I have a large box full of them. We hear disposable grocery bags are evil so we should use other bags which take hundreds of times the resources to make but don't last 100 times longer. The carbon trading schemes seem to be another way for governments to print a different type of money and set up trading tariffs while pretending to encourage free trade. We hear about planting trees to sequester CO2 yet the current plan means the land will hold less carbon that it did 100 years ago yet this is somehow a carbon credit. Start looking at many of the scams using a double entry accounting system and you start to see they don't pan out. Of course pointing out wrong numbers in any of this gets one labelled a denier real quick.
If you agree to help someone launder stolen money, that is a crime in most countries even if the money doesn't exist.
One of the more successful scams now involves stealing email accounts of travellers and sending all their friends a note describing some sort of robbery and asking for money.
One example was the crackdown of sharing done by the US AF academy but it accounts for a less than $1000. The musicians had been approached for a gig but couldn't get samples to the other committee members in time to meet their cut-off time.
For my decade old saab it costs nearly AU$1000 for a 6 disk changer. Or $200 for a big ipod and bit less than that for a device that pretends to be the factory CD changer but allows all songs on an ipod.
I run a web site for local bands where I give away their MP3 and a few bands have ended up with international gigs because of it. Some of their older songs may have names that new RIAA approved songs happen to have which results in nasty letters from lawyers. I know of at least US$20,000 worth of losses due cancelled gigs due to to RIAA paranoia so far. The RIAA isn't about music, they are after moving small plastic things. If you don't think the RIAA is out of hand, how much should the senators who sung God Bless America on the steps of the Capital pay the Boy Scouts? The law is the law isn't it?

Teh big cost is dealing with the debug output. Thats why some programs have used category.level debugging for decades. An example would be sendmail's -d 1-99.99 shows you everything but -d 27.10 will show debug levels 1-10 of just the alias processing code.

One key issue is that systems on boot may not have access to all the libraries that make bash a nice human interface. A core system needs a shell that uses no shared libraries at all and does only simple things to start up programs (like a real shell)... If all that can be kept in nice clean text files that include #!/bin/sh to indicate that they won't be doing anything complicated, then it makes it much easier for developers. While I love to use bash, I wouldn't ever consider if for the rc scripts or single user mode if I had an option.

US medical insurance is provided by employers since congress decided that was a good idea. Before that happened, many groups would offer group medical insurance.
The music business is controlled by people who sell little plastic bits and they only see the music as a necessary evil that is in getting consumers to buy more plastics discs. They don't like the idea of millions of bands because stores have limited shelf space and the logistics wouldn't be profitable.
