So what do you do if:
you got a new computer, or maybe a software upgrade, only to find — error message! — that some of your old files are incompatible.
and the files you have are valuable historical data needed for current research? How about finding a USB compatible Hollerith card reader?"

While I have read this before and do find it interesting, I grew up with a kinda rhyming mnemonic:
Thirty days hath September
April, June and November
All the rest have Thirty-One
Except February which has Twenty-Eight (or Twenty-Nine)
Although the wiki one is a little better:
There's something missing - a downmod of "you are factually incorrect". Not "I disagree"
What's wrong with -1 Overrated?
I've have used "-1 Overrated" for that purpose in the past, but only in articles that I have modded in previously and feel strongly about the bad info being presented. If I have no mod points invested in the conversation and I feel strongly about it, then I comment.
You should reread the thread. It was not I who invoked the Nobel prize. I do not do ad hominems or taunts, I find rudeness interferes with the promulgation of knowledge.
So how many meters per second per second is his velocity towards the center of the earth increasing?
No acceleration, gotcha.
Force can cause acceleration, force does not equal acceleration.
Precisely, the hangman put the noose on you and you have the force of gravity pulling you down, it is not until he opens the trap door that the force of gravity accelerates you downward to snap your neck.
So you are saying that I can use an accelerometer in order to determine that bulk of mass in the cosmos is accelerating away from us? How do you propose to determine acceleration of an object that you do not have physical access to?
You just continually monitor the distance between yourself and the target and can compute both your speed and your acceleration by comparing the distances over specific time intervals. As you take the interval times to zero, you get better and better approximations of your exact acceleration curve (that's pretty standard calculus -- sample and integrate.)
And each time you note the position you create a new reference point for the following position.
That would be inertia.
Following your logic acceleration would not be detectable either therefore pointless.
In order to detect acceleration, you must take at least 3 sample points of reference of the object in motion. The first to set a starting point, the second in order to set an velocity and the third in order to set a later velocity with this information you can detect the change in velocity.
Without these an object in empty space would never have velocity therefore no potential increase in velocity.
oops, sorry about responding to myself, but I messed up my link. I'm more of a hardware guy.
The AC who responded to your comment is completely wrong.
While deceleration is used in common speech to indicate a reduction of velocity, in physics there is no deceleration only acceleration in the opposite direction of the trajectory. Both concepts, acceleration reverse acceleration, require a point of reference, in this case it is the sun.
I would have been disappointed if
"New York has now ranked as the 5th best-dressed city in the nation, behind rival Boston."
"Manhattan is 5th worst dressed city in America: GQ magazine, Boston ranks number one."
Besides what does guys who dress like douchebags have to do with geeks and their fashions.
I agree with your point about a random auto mechanic not allowing you to use his or his employers equipment. I work on cars and computers and other things regularly and if some random person asked to use my equipment to test their stuff, I would feel they were wasting my time, but I am trying to sell a service and I make no money on replacement parts. But, most auto parts stores (even ones with service sections) will test batteries, alternators and starters for you for free if you remove the item from your vehicle and bring it in to the store. I have never brought a starter motor into a parts store/service station and had them tell me to put it back into my car and to bring the car in for their mechanics to test it.
Circuit City/Best Buy have more in common with auto parts stores with service sections than with a repair only auto shop.
Personally, I think it is foolish for a business that sells component/replacement/upgrade parts, which only pros, semi-pros and hobbyists are going to purchase, to not attempt to ingratiate themselves with these persons. In all likely-hood, if a person brings in a component part and it tests bad, that person will purchase a replacement from that same location as long as it is available, besides, these are the same people that are going to make more purchases of repair parts than any other demographic. If they are not interested in this demographic, then they should not waste their floor space with repair parts at all.
Why would you use up perfectly good bourbon on driving somewhere?
To get more bourbon.
