it's that you can't stock Digikey on the space station, but can "print" all of the knobs, buttons, and switches you need when one breaks.

And another, when that one breaks, which it will. Still, no problem - just print another another one...

Might as well take a tub of Play-Doh.

I, however, want privacy, free speech, and other fundamental rights. I recognize that a life without these things is not a life worth living.

Try going without food for a couple of days and spending a couple of winter nights in a shop doorway. You won't be talking so tough then, kid.

As I've said, that's the field known as Genetic Algorithms. It's a fun area and highly promising in some fields of work, but the contexts are too simple and the algorithms are too naive. A good example of a naive Genetic Algorithm is the one used by stock brokers to game the system. It "works", but only if the system is well-behaved. But, by working en-masse, it causes the system to not be well-behaved. Because it's naive, it's incapable of evolving to deal with this.

No I don't. I do not subscribe to Professor Penrose's Chinese Room argument. You do not understand my argument and that's perfectly obvious. The more you shout, the deafer you show yourself to be.

No, it's not "completely false". It's standard AI thought. Your examples show nothing because you do not comprehend the thought. You'd probably do better to ASK once in a while than to argue with someone older and wiser. Now get off my lawn!

ISS's 3-D Printer Creates Its First Object In Space 68

An anonymous reader writes: NASA reports that the 3-D printer now installed on the International Space Station has finally finished its first creation. After it was installed on November 17th and calibrated over the next week, ground control sent it instructions yesterday to build a faceplate for the extruder's own casing. The process was mostly a success. "[Astronaut Butch Wilmore] Wilmore removed the part from the printer and inspected it. Part adhesion on the tray was stronger than anticipated, which could mean layer bonding is different in microgravity, a question the team will investigate as future parts are printed. Wilmore installed a new print tray, and the ground team sent a command to fine-tune the printer alignment and printed a third calibration coupon. When Wilmore removes the calibration coupon, the ground team will be able to command the printer to make a second object. The ground team makes precise adjustments before every print, and the results from this first print are contributing to a better understanding about the parameters to use when 3-D printing on the space station."

How the World's First Computer Was Rescued From the Scrap Heap 120

anavictoriasaavedra sends this quote from Wired: "Eccentric billionaires are tough to impress, so their minions must always think big when handed vague assignments. Ross Perot's staffers did just that in 2006, when their boss declared that he wanted to decorate his Plano, Texas, headquarters with relics from computing history. Aware that a few measly Apple I's and Altair 880's wouldn't be enough to satisfy a former presidential candidate, Perot's people decided to acquire a more singular prize: a big chunk of ENIAC, the "Electronic Numerical Integrator And Computer." The ENIAC was a 27-ton, 1,800-square-foot bundle of vacuum tubes and diodes that was arguably the world's first true computer. The hardware that Perot's team diligently unearthed and lovingly refurbished is now accessible to the general public for the first time, back at the same Army base where it almost rotted into oblivion.
