The general mainframe design is essentially targeted at the application profile of a static-page webserver. Simple programs, quick data access and throughput, no computation. They are utterly unsuitable for any computationally demanding task.
Evidently you didn't read the article. Mainframes are not compute machines, they are I/O machines. Your screed on DASD shows that you have no experience with a single machine or application that can generate 250,000 I/O operations per second for days on end without falling over dead. Yet this is common off-the-shelf mainframe work.
Why would you want the directors cut ? Directors cut is what runs in the theater.
Not always. Many movies are cut on orders from the studio, often for length if nothing else. Other things may be added or taken out if the moneybags don't like what the director came up with. Blade Runner is an example; the director's cut is a much better movie than the original release.
But that's not a DMCA violation. That's breech of contract, or potentially a violation of trade secret laws, not a copyright violation which is what the DMCA covers.
Here's an older DejaView message on the topic. It addresses this very issue.
Undergraduate physics:
Resolving power R (resolution) of a diffraction limited telescope: R = wavelength/(2*diameter telescope)
This means for the HST (2.4 meter) and visual wavelenght (500nm) R = 500nm/4.8m = 1*10^(-7)
Since the Hubble is in orbit h = 680km (380 miles) high, this means it can theoretically resolve: Detail = R * h = 0.07. Thus 7cm (3 inch) details. Not enuff for reading license plates, even if someone would hold it up to the sky so we dont have inclination effects. Besides this, the best visual wavelength camera on board (the PC chip on the WFPC2 camera) UNDERsamples this signal by a factor of 2 giving an effective resolution of 14cm (1/2 feet).
This holds only if we ignore atmospheric turbulence effects (which certainly DONT average out), the pointing instability (up to about 10mas (micro-arcseconds)) and thermal breathing (up to 10mas). This degrades the image even further. (10mas translates to about 5cm as seen from the HST)
Furthermore, target acquisition is problematic. HST uses guide-stars, which need to be in the field of view, to lock on targets. Certainly no stars available on the face of the earth;-p. Even then: A quote from the HST data hanbook: "It is also possible to take observations (primarily WFPC2 "snapshot" exposures) without guide stars, using only gyro pointing control. The absolute pointing accuracy using gyros is about 14" (one sigma), and the pointing drifts at a rate of 1.4 +/- 0.7 mas s**-1. "
So, we have a 66% chance of 14" (arcseconds) acquisition accuracy. This translates to about 1400 pixels offset (if we were well sampled) on a ccd camera or 100m inaccuracy on the ground.
Say we want a spy satellite with 1cm resolution (ignoring degrading affects) on orbit 300km high (if lower, atmospheric friction would cause it to fall back to the earth), then applying the same formulae as above we would need a telescope diameter of roughly 5 meters. (According the the space shuttle reference guide you would have to keep the payload doors open in flight to make it fit, hehehe)
Conclusion:
IMBO the NSA cant read license plates. The technology for space telescopes with this capability is only now being developed (look for NGST on the web) against HUGE costs, certainly not within the NSA's budget. Besides target acquisition is a severe limitation, and it's role becomes more important when the resolution increases.
Well, my comment was based on the laws of physics. You can throw as much technology as you want at the problem, but it's physically impossible for a Hubble-sized mirror, looking straight down from Hubble's altitude, to read a newspaper headline. You would have a hard time even telling that you were looking at a newspaper.
We should avoid using spy movies as a basis for estimations on what our government is capable of.
just imagine what we are capable of now right in our back yard.
Not as much as you might imagine. A Hubble-sized telescope in orbit at Hubble's altitude, pointed straight down, can resolve down to 15 centimeters. That would be enough to tell that you drive a Honda instead of a Surburban, but it couldn't tell much beyond that.
But maybe the sight of some 40-something, balding fat guys does something for you, I don't care.
Depends on the music they are playing. If they are playing the same stuff they were playing when they were 25, you're probably right. But there's nothing preventing 40-something balding fat guys from playing new, innovative stuff. So, on behalf of all 40-something balding fat guys everywhere, I heartily invite you to stick your music bigotry where the sun doesn't shine.
On the contrary, my dear Watson. What if I change something in my Word document, but later on decides it was no good and wish to discard it? Nope, sorry. My old document is already rewritten with no turning back. Or is he suggesting that everyone should always make a copy of a document before editing it, just in case? Wouldn't THAT seem terrible unintuitive? RSX-11, way back 20+ years ago, did not overwrite on save. The file name had 3 components (not 2), the last being a version number. A save automatically saved with a version number one higher, and didn't touch the older versions. If you just specified the two components (name.type), you always got the latest version. If you wanted an earlier version, you specified name.type;version and you got it.
Officially, yes. However AIM has this obnoxious habit of trying all sorts of non-standard ports. One network I set up (the managers wanted AIM shut down), I had to put up a http proxy server and close off port 80 from the users, and it snuck out port 53 (DNS). The AIM programmers went out of their way to evade firewalls.

Mainframes do things PCs cannot do, mainly I/O by the truckload. That is unlikely to change.

Rosebud was the sled.
Screw the window seat. More legroom on the aisle.
You mean like like here?
SecurityOffice.net is in Turkey. We've probably slashdotted the entire country's bandwidth.
Well, it is running Linux, but it's in Turkey. So much your blame game - what we're slashdotting is not a server so much as an entire country.
But that's not a DMCA violation. That's breech of contract, or potentially a violation of trade secret laws, not a copyright violation which is what the DMCA covers.
Wouldn't have helped. A halon system in the server room doesn't do much when the entire building goes up.
It only takes one person.

generally speaking, spammers will unsubscribe you. Ever tried to unsubscribe to junk mail? Impossible.

I guess that takes care of the "existing business relationship" part.

Wasn't the published MD5 changed to match the trojaned code? I believe that's what happened in the earlier case.

Yup.
It doesn't seem like there would be that many books in the public domain that haven't already been made available on the net.
How do you suppose they make it to the net? Most of the public domain books were written before word processors, so there's no electronic text around.
Of course I could be wrong.
Yeah. Go look at Project Gutenberg's site - think of it as you homework assignment for the weekend.
I can't decide if this is a joke or not.
You do know about Project Gutenberg, right?

Hmmm. Doesn't Microsoft-supplied encryption still have those NSA-supplied keys?
