Technically, processing does not necessarily require power dissipation, only deleting does. So if you make sure you have 2-output gates (so the processing can be reversed--otherwise information is deleted), you can make your processing take as little power as you'd like. But, just as with the underlying problem with achieving absolute zero, the processing can never actually dissipate absolutely zero power.

Submission + - Ask Slashdot: How smart are the new British porn filters?

professorguy writes: I have a little personal website (since 1997) that contains links to essays about horology. In one of the essays, I discuss the merits of bridges (a component of a wristwatch) as compared to cocks (a slightly different component of a wristwatch). The link appears on my site as "Why I Prefer Cocks."

Now I hear about the new opt-out filters for UK ISPs. This brings up several questions:
— Is the cock link visible through the filter? The page? The site?
— If not, if I change the link to something less ambiguous, will the missing piece(s) reappear?

UK slashdotters with ISP filtering, please compare these 2 links with these 2 images:
Site: http://professorguy.comWhat it should look like
Horological page: http://professorguy.com/blogWhat it should look like

I guess my real question is How smart are these filters? Thanks.

Submission + - Ask Slashdot: Is Google really getting infinite copyright extension? 1

professorguy writes: Google Earth once displayed an image of our small, rural town taken in 2005 marked (c) 2005. I noticed that in 2009, Google Earth displayed the SAME IMAGE but marked with (c) 2009. In 2011, the copyright date changed again but the image did not. Today I noticed the copyright date is now 2013, but it is the SAME IMAGE from 2005. It seems they got an 8-year copyright extension on their image.

Does Google get infinite copyright extension by simply continuously 'republishing' the same content? Does this mean no Earth image will ever be in the public domain? Can I just update the copyright dates on my own web content and get a free 15-year extension?

Anyone who owns and carries a firearm has a responsibility to demonstrate iron-clad self-discipline and sound judgment.

Well said. This is why I am a staunch supporter of gun ownership, but own no guns myself. As a service to society, I have judged myself unable to bear the heavy responsibility.

But I am very happy other private citizens, who have stronger character, own guns.

Comment Science WILL progress. Unless we stop it. (Score 1) 315

Science WILL progress regardless of idiotic laws and politics.

I hadn't heard about the scientific progress of the Cambodians under Pol Pot. Progress must have occurred since mere LAWS could never stop it.

Sarcasm aside, I think you meant "regardless of idiotic laws and politics, as long as they are not TOO idiotic. " Unfortunately for all of us, it is very difficult to determine the exact location of the "TOO idiotic" line, and current politicians seem to be pushing as far as possible.

Comment A note about darkness (by a producer) (Score 1) 399

My wife and I make our own syrup. This year was a poor production year (we got HALF of what we usually get), prices have soared and thefts like this suddenly have a big payoff.

But the "darkness" is more complicated than just the reduction. Since it is the COOKING and not the reducing that caramelizes the sugar and makes syrup dark, you can make lighter syrup by reduction without cooking.

That's why light syrup is so easy to get now since most producers use reverse osmosis to remove some water before cooking (to save energy) and thus cook it for less time. In fact, I've heard of producers here that do so little cooking, they add molasses to the final product to darken it so it looks like homemade syrup.

The late season stuff (known as "bud syrup" because the trees have already started to bud out) is always darker than the early, but that matters much less than cooking method.

Comment ebooks cannot be HIDDEN (Score 1) 207

I like ebooks. Convenient to get & search and you get modern functionality (font size control, updates, smart indexing, etc). What's not to like? Only one thing: Giving up paper copies means giving someone else control of your library.

Even if you "download" ebook content and keep it out of the cloud, how are you going to read it? Oh, just use a networked device which.... oh, right, that's a fail because devices in the future will not even display forbidden content (and will report your attempt). Never happen because devices like that don't exist and besides people wouldn't stand for it? I was once told no one can possibly keep track of the websites you visit because that mechanism didn't exist and besides people just wouldn't stand for it. How'd that work out?

Only paper can be hidden and read back later without electronic intermediation. That means ONLY PAPER CAN BE HIDDEN. History tells us all unhidden documents are eventually taken. So use your ebook to read the latest thriller/romance/pulp. But PRINT ANY BOOK YOU WANT TO GIVE TO YOUR KIDS.

Comment Big difference (Score 1) 288

First of all, if they wanted to track you; then they'd sure as hell do it no matter what.

This is a weak argument. If they wanted to track YOU, this is certainly true. But if they wanted to track EVERYONE, then they'd need the kind of system described here. There is a fundamental difference between the 2 situations.

Comment So now EVERYTHING is powered? (Score 2) 414

So they've convinced us that WASTEPAPER BASKETS must be plugged in at all times (shredders and so-called "electric dustpans"). And I see everyone out with gas-powered BROOMS. And even the SAP which drips freely from our maples is, in modern sugar houses, vacuum pumped to a tank.

And now there's 200 comments where the people are proud of their kilowatt server arrays which are powered 24 hours a day for their PHOTO ALBUMS? Are you people shitting me? I mean, you're putting me on, right? You don't really use up 10,000 kWH per year storing your family photos, do you?

Hey, I've just invented the electric elevator-button-pusher. I save a TON of finger wear and tear.

Sometimes, humanity makes me sad.
