You can't prove a negative

It's called proof by contradiction.

No you have it backwards, proof by contradiction is a method of showing something is true by showing that if it were false it would be a contradiction with something known to be true. An example in this case would be to say,

"assume there are purple unicorns, that would imply through a chain of logic that there can not be pink spotted elephants, since we know that pink spotted elephants do exist then purple unicorns can not exist, QED"

since you are likely to have difficulty finding a contradiction that results by assuming that purple unicorns do exist this method of proof it unlikely to helpful in this case.

What the fuck?

The illegibility that you find so shocking would seem to come from the terminal the poster is using (based on their previous comments) the content would seem to come from the fact that all they appear to want to do is assert that various political view points are bad along with those who hold them regardless of how relevant it might be to the discussion at hand.

Or their views on the world may just be the result of living in Seattle and not having sex for 20 years, can't tell which is the cause and which is the effect.

If you go to the USPTO trademark search and put in "multimeter and yellow" the FIRST result is a Fluke yellow multimeter.

If you are in the business of making multimeters and claim you have never heard of Fluke or seen one you are clearly full of it.

Company caught clearly knocking off other company's product tries to play the "trademark laws is bad, boo hoo" card.

No you misunderstand the nature of recovering data from a HDD. It s not that the data from the 49th overwrite could be recovered, it is that the data from the 1st write might be recoverable. How is it that the data from the 1st write could be recovered but the data from the most recent couldn't be? Because if the 1st write sits for a long time then 1 that was written to the drive when over written by a 0 becomes not a 0 but a 0.1 or the 0 overwritten by a 1 becomes a 0.9 not a 1. so while the drive itself is not going to be able to recover anything if you just write 0's to the whole drive, someone with better equipment that is prepared to read the drive over and over may be able to sift out the 0's and the 0.1's as if they were 0's and 1's. So by randomly writing 0s and 1s back and forth you give all the bits a randomized amount of magnetism and make it unrecoverable.

So if the disk had one set of data stored on it for an extended period of time and then you wrote a new set of data there would be a period of time where you could 0 the drive and potentially recover the first set of data, so at most you could say the drive contains somewhat less than 2X its rated capacity, with great difficulty.

I'm sure the government will step in and protect us from these products just as they did with Buckyballs.

Buckyballs were sold as adult office toys and the Consumer Product Safety Commission still felt the need to save the children from swallowing the ball magnets. Given that these say they are for ages 8 and up I don't think they stand a chance... which is sad because they certainly look like they could be a lot of fun.

Clearly what they need to do is include an "Emergency Extraction Super Magnet Rescue Tool" (that is too big to swallow) with each set along with a DVD copy of the movie Fortress, and print "Rescue Tool Instructional Video" on the DVD, and then they should be good to go.

It's not a "lie" if they aren't convicted, and even then for most people it will still be a "misstatement".

The win at all costs nature that American politics have turned into as of late have made seeing just how blatant a lie you can get away with part of the game rather than something to be avoided.

Asking nicely for his removal will accomplish nothing at all. Either go for conviction or don't bother. Saying "he's not nice and we don't like him anymore" is not going do anything other than cause the administration to chuckle.

One of my most favorite museums in the world used to be the Science Museum in London, then I visited it and discovered the steam engine in the entrance doesn't run, the ship model gallery has been sent to storage never to be seen again to be replaced with a gift shop, I couldn't find the working Babbage engine section, in fact basically every display I wanted to see was gone and replaced by junk.

These so called "modernized" displays are nothing better than what you could read online, I want to go to a museum to see *actual* history, not to see a cartoon representation of a simplified version of history that assumes I am a moron.

I think the curators of science/technology museums need to view themselves in the same way as curators of art museums do, their purpose is to display the "art" not to tell me about the art with pretty cartoons after they ship the art to the storage warehouse.

Can't imagine what makes you think I am British.

You presume I have no personal experience, you believe that because you have been in prison that your experience speaks to the behavior of the average convict, yet you even admit that they behave better inside than outside and yet it is the out side we talk about.

As for giving a mother advice on child birth without being female, You do know that the vast majority of OBGYN doctors are male right? So the vast majority of women who give birth do so with the advice of men.

I thank you for a wonderful post demonstrating the danger of observational bias in forming peoples belief systems.

This is daft, the hardened prison inmate is almost 100% certain to view you as prey and to happily exploit your trust. Your understanding of people is simply backward, the convict *will* fuck with you if he wants to, you need not "give him a reason to". Your average church goer on the other hand almost certainly needs to be given a reason to care about you. You may not find acceptable the things that would cause the church goer to take an interest in you. But if you believe that as long as you do nothing to attract their attention you are safe from the average convict you are dangerously deluded.

Just happened to be staying in the same hotel and I don't recall what started us off but some how we struck up a conversation and he wound up telling me some great stories.

The story about the guy in the FexEx box is even better than the article makes out. Since they couldn't actually ship a person via FedEx for many reasons, the box had to seem to come from the right location which would have meant putting it on a plane, and what not. So to make it all look right Steve got himself a real FedEx uniform and put FexEx stickers on the side of a van and even had one of those scanner guns the delivery people used and pretended to be a FedEx delivery person in order to drop off their "package". As I recall he even picked up all their out going FexEx packages and dropped them off at the local FedEx center to fully make the deception work.

It was one of my more interesting random conversations, at some point they should write a book about this stuff, he had lots more stories than just this one. But yeah basically if someone really wants to get inside your building and steal your stuff badly enough they will.
