The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

But it will still save on electricity

Even for the crazy world of quantum mechanics, this one is twisted. A quantum computer program has produced an answer without actually running.

This scheme could have an advantage over straightforward quantum computing. “A non-running computer produces fewer errors,” says Hosten. That sentiment should have technophobes nodding enthusiastically.

Via Flares into Darkness, Quantum computer works best switched off

While it's true that a computer turned off produces vast amounts of nothing really fast, so does a burned out light bulb. And the very fact that there's still a program means there are bugs (proof? “Every program has at least one bug and can be shortened by at least one instruction—from which, by induction, one can deduce that every program can be reduced to one instruction which doesn't work.” Q.E.D.”) so it's still far from evident that a non-running quantum computer will have fewer errors than a running quantum computer.

I guess these guys haven't heard of Heisenbugs.

Obligatory Links

Obligatory Miscellaneous

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site: http://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

http://boston.conman.org/2000/08/01

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.

It is assumed that every brand name, slogan, corporate name, symbol, design element, et cetera mentioned in these pages is a protected and/or trademarked entity, the sole property of its owner(s), and acknowledgement of this status is implied.
