Comment Re:It seems like squeegeeing is the wrong approach (Score 2) 203

For a human, using a sponge and squeegee combo is probably the most effective way to clean a window. For a robot, I would imagine that the answer is something more like a pressure washer, with a hood which covers the work area and reclaims the wash water. The water would then be filtered and reused until the particulate count rose too high, at which point it would be flushed and replaced with fresh. A sheeting additive would be used to cause the water to run off without spotting.

This probably wouldn't replace human window washing entirely, but it seems like it has the potential to replace at least some of the washes.

I've often wondered if anyone has ever tried a project to make a building which washes itself, using a robot designed for the building, and a building designed for the robot. I can imagine many problems with such a project without even undertaking it, mostly related to critters taking up residence in the mechanisms and/or tracks, but if it operated continuously that might well eliminate some of those objections. A universal window washing robot has a more complicated task than such a device would.

Did you even read the article? You'll find it discusses how the old World Trade Center Towers had built in devices that were made specifically for the building that would automatically go up and down cleaning it. The only problem was they missed the corners and creases of each pane and the rich people at the top of the building didn't want the grimy borders to their new expensive view of NYC.

It sounds like you have a lot of ideas for building a nice big heavy expensive machine that moves up and down a building. Burst forth and implement your idea, I think you'll find that the the weight, the power and the water feed to these devices will push you towards what has already been implemented and did not do a satisfactory job. Humans had to follow up behind the built in robots to clean spots they had missed.

It's funny, I read articles on Slashdot about how AI is the one thing that threatens man. And we can't even implement AI and pattern recognition to replace a window washer -- oh the incongruity!

Comment Your Thoughts and Use of Post Processing? (Score 3) 35

So I'm not too knowledgeable on photography but one thing I'm aware of is that professional photographers do a lot of post processing. To the point of Adobe Lightroom or higher being so mandatory with DSLRs that they sometimes package it with lenses (especially the ones that distort like a wide angle lens). Do you post process your photos? To what extent? How do you feel about people who use advanced techniques like even adding color to their photos? For example, I came across this photo which was odd to me because I've been to that place and it's beautiful but not like in that photo -- it doesn't need fake pink clouds to be beautiful. It would seem to me a shame to have a tree live 2,000 years and then a human uses a fish eye lens on its knotted trunk to make it seem more old and gnarled and then later adjusts the darkness of the sky to give it a Halloween feel, etc. And then since that's the most artistic shot of it, that's how we remember it.

Now that I think about it, if Philae did not bounce off of the comet, then the screws must be doing their job and I would think the harpoons might not be needed at all. I would assume the harpoons were in the plans because the engineers couldn't be sure the screws would work on the surface of a comet.

My understanding is that the harpoons were one of two ways that ESA was going to secure the probe to the comet. There were also screws that were supposed to attach the legs to the surface. So if they can still fire the harpoons they ought not have an issue with Philae flying off into space, but does anyone with more information on the relative strength of each? And if the harpoons could not be fired... what is the real risk of the probe shifting? I mean what would cause it to shift in the first place once settled on the comet?

Comment Be the Change You Wish to See in the World (Score 5, Interesting) 438

When I was younger and I first came across this quote by Mahatma Gandhi:

You must be the change you wish to see in the world.

I always thought it was bizarrely tautological. If you wish something to be different and you personally can make a choice for it under your control to be different, then you make the correct choice. For example, I don't throw a soda can out the window of my car while complaining about pollution on the highway. Other people obviously don't care but I control the drop in the bucket I'm responsible for and I make the ethical choice.

But as I got older, I actually found and still find people that think they should be forced to do it the right way even while complaining about the abuse. Case in point, a friend in the medical profession was actually complaining about tax dodges while setting up his own backdoor Roth IRA. When I asked him about abusing the very rules he was decrying, he simply shrugged and said he doesn't make the rules he just follows them. He acknowledged it's shady as hell but pretty much felt like his hands were tied.

It was deeply troubling ... I get a similar feeling about this article. I understand it is sometimes harder to play by ethical rules than legal rules when everyone around you is benefiting from misconduct but ... it seems this is yet another example of the caste system thriving in India. It's simply stupefying on the "My dad is Li Gang" level.

Scientists Discover a Virus That Changes the Brain To "Make Humans More Stupid" 275

concertina226 writes that researchers have found a virus that appears to reduce people’s thinking power and attention span. "Scientists at the Johns Hopkins Medical School and the University of Nebraska have discovered an algae virus that makes us more stupid by infecting our brains. The researchers were conducting a completely unrelated study into throat microbes when they realized that DNA in the throats of healthy people matched the DNA of a chlorovirus virus known as ATCV-1. ATCV-1 is a virus that infects the green algae found in freshwater lakes and ponds. It had previously been thought to be non-infectious to humans, but the scientists found that it actually affects cognitive functions in the brain by shortening attention span and causing a decrease in spatial awareness. For the first time ever, the researchers proved that microorganisms have the ability to trigger delicate physiological changes to the human body, without launching a full-blown attack on the human immune system."

Comment Self Censorship in Your Industry (Score 1) 58

I've never really enjoyed main stream comics but the imprints that dodge the archaic Comics Code have pulled me in with various titles -- some of yours even. According to your wikipedia page you left Hellblazer after DC refused to print a controversial comic of yours in such an imprint:

He left that series when DC announced, following the Columbine High School massacre, that it would not publish "Shoot", a Hellblazer story about school shootings, although the story had been written and illustrated prior to the Columbine massacre.

Is this common in comic books/graphic novels? Have you experienced this elsewhere in your career? Do you feel that DC and other big publishers are too afraid of another Fredric Wertham to toe the line?

Comment Concern or convenience? (Score 5, Interesting) 165

I wonder if some of these folks were already regretting their decision to tie up money in a space flight. People's finances change, life situations change, priorities change... and this is a convenient way to try to get out of the financial obligation.

No evidence on my part... just idle speculation.
