Will Your Next Car Be Covered In Morphing Dimples?

mark_reh Re:Cars are fast enough already (111 comments)

The laws of physics are symmetric and apply equally to the people in the car and outside the car. The last thing you want is to stop a car dead at any speed.

OK, so the car has airbags to protect the occupants. Do you really want all the air bags going off every time a car is within striking distance (whatever that means) of a pedestrian or bicycle? There is no airbag between your brain and the inside of your skull. THAT is the real problem that needs to be solved.

I'd say what really needs to be focused on is educating people not to walk in front of cars.

The Psychology of Phishing

mark_reh How are they outmarketing the experts? (121 comments)

That's easy. They don't care about laws that are intended to protect people from "legitimate" marketers. When you don't worry about the law you can literally do and say whatever you want.

Intel Launches Self-Encrypting SSD

mark_reh Re:Intel has worked with the NSA (91 comments)

How long do you think you'll keep your pass phrase secret when one of the government sanctioned torturers tightens the screws on your thumbs?

You can't protect your data from the government any more than all the gun "enthusiasts" in the US can protect themselves from the government with their guns. The government ALWAYS has ways and means beyond what any individual or even any group can muster.

People Who Claim To Worry About Climate Change Don't Cut Energy Use

mark_reh I gave up a long time ago. (708 comments)

At this point, considering the inability of congress to get anything done, maybe all those people who believe the scientists about AGW have come to the conclusion that it's too late to do anything about it and have given up. Or maybe they realize that changing their personal lifestyle is nothing compared to the size of the problem.

I lived in Phoenix for a while. Golf courses everywhere. No water anywhere. Billboards reminding me to use less water everywhere. The message I got was that I should feel guilty about every drop of water I used so a bunch of rich a-holes who spend their winters in Phoenix could have more water to dump onto their golf courses. AGW is a lot like that.

The change has to start with the most visible and egregious offenders. Then people will see that there's something going on that they should be concerned about and will modify life style en masse. The only way to deal with the most visible and egregious offenders is via the law. Unfortunately, those offenders have money and use it to keep congress in a perpetual state of suspended animation, because it is through their offense that they make their money.

Chinese Couple Sells Children To Support Online Game Addiction

mark_reh Re: Scare story (131 comments)

Their "teeths" fall out because of multiple factors. They don't take care of them, they tend to drink a lot of soda and eat a lot of candy bars instead of eating actual food. They are often subjected to violence that results in traumatic damage to teeth. Other than trauma, the damage occurs over a period of months to years and they can see what is happening in a mirror as it happens, but the attraction of the drug is so powerful they can't stop. I occasionally see them and extract some or all of their teeth. Their visit is usually precipitated by pain or by an attempt at rehabilitation.

Amazon Seeks US Exemption To Test Delivery Drones

mark_reh Re:won't work (155 comments)

I think Amazon's drones are going to stay close to the ground. Limited battery capacity means flights have to be short, especially carrying 5lb payloads. It seems more likely that a truck will pull into a neighborhood, open the doors and release a bunch of drones to drop packages for that neighborhood. They will then return to the truck and be driven to the next neighborhood where the process will be repeated.

Unless they come up with nuclear power, that's going to be the limit of their use.

The problem is that a 5 lb payload traveling at 50mph can do a lot of damage if it hits something, to say nothing of the damage the whirling blades could do. A 5 lb package dropped from 1000' would certainly kill someone.

These drones won't be used in rural areas because of the distance between delivery locations. They won't be very practical in urban areas because of the density of people and other things that could get damaged. They are best suited to suburban neighborhoods where potential delivery sites are close, but not too close, and power lines, etc., are minimal.

I don't think Amazon is overly concerned about people shooting at delivery drones. I'm sure they'd lose a few to gun "enthusiasts", and those stories will certainly make headline news because the press is stupid and gives gun "enthusiasts" publicity anytime they demand it by doing something stupid with a gun, but there are existing laws that cover shooting guns in populated areas and after a few get arrested, others may be discouraged from engaging in unsafe behavior.

Researchers Develop New Way To Steal Passwords Using Google Glass

mark_reh It seems so simple... (116 comments)

Why doesn't someone just modify the snippet of code in the OS that displays the touch keys on the phone/tablet screen to place them in a new random order each time you unlock the device so that when you enter the PIN to unlock the device you never use the same finger placement pattern twice? That would also prevent analysis of scratches/smudges on the surface of the device as a means of cracking it.

I know, I know, users would probably complain.

When Beliefs and Facts Collide

mark_reh Re:There's belief, there's facts and there's polit (725 comments)

Congratulations. It is obvious from the Republican party's platform and statements made by leadership to news media on a daily basis that believing in AGW is NOT a Republican thing to do. You're an outlier, not a mainstream Republican.

I find it interesting that you ask about democrats who don't believe in AGW. It's as if the existence of AGW is a matter of opinion. You're in a group that denies science - not just AGW, but also evolution, and probably other things- i.e. the group you are in chooses ignorance over reason. To equate that position with believing AGW and evolution is ridiculous. AGW and evolution are based on science. It isn't a matter of belief. If there is a democrat who denies the science behind AGW they, too, are ignorant.

Your implication is like the ID advocates who equate their position with the position of scientists who study evolution. The positions are NOT equivalent. ID advocacy is based on nothing but poorly camouflaged religious ideology, evolution is based on 100+ years of research.

In US politics, the opinions of stupid/ignorant people are as valuable as those of intelligent people- everyone gets one vote. In real life, stupid/ignorant people can't accomplish much. But politicians don't care about what people can accomplish- they just want the votes and they know that there are a LOT of stupid/ignorant people out there waiting to be told what to do, so the message gets crafted to appeal to the hordes of the stupid and ignorant. You should be proud of yourself for being an integral part of that process.

15-Year-Old Developing a 3D Printer 10x Faster Than Anything On the Market

mark_reh Re:speed is not really what they're lacking (203 comments)

Avoid touching the printbed with your bare hands- oil from your hands will prevent prints from sticking. Before you print, make sure the bed is clean by wiping it with acetone while it is at room temperature.

15-Year-Old Developing a 3D Printer 10x Faster Than Anything On the Market

mark_reh Re:speed is not really what they're lacking (203 comments)

Rounding the corners of your box, if the design constraints allow it, will help prevent corner lifting, as will using a brim about 5-6mm wide when printing the first layer.

15-Year-Old Developing a 3D Printer 10x Faster Than Anything On the Market

mark_reh Re:speed is not really what they're lacking (203 comments)

The lifting at corners of a box is caused by the shrinking of the plastic as it cools. There are straight lines of plastic connecting the corners which concentrates all the force from the shrinking there. If you make the surfaces of the box wavy instead of smooth and flat you'll have fewer corner lifting and delamination problems. The other thing you can do is enclose the printer in a box that keeps the whole print warm as it prints. I have found that a temperature as low as 40C inside the box is sufficient to prevent most delamination problems in ABS prints.

I enclosed my printer in a box made of PIR foam. See: http://www.thingiverse.com/thi... The box clips together using 3D printable clips that allow you to take the box apart and reassemble it easily. I don't think it is entirely necessary to use insulating foam- I think a single layer of corrugated board would work just as well. My printer heats the box to >40C with the heat from the printbed alone.

ABS should stick to the kapton covered printbed without any assistance from "juice" or other additives. If your prints don't stick, you probably need to be more careful about leveling the bed and zeroing the Z-axis. Print the first layer slowly with the extrusion multiplier at 200%. It is entirely possible that your printbed isn't very flat and that can lead to prints lifting because no matter how well you level the bed and set the Z-axis zero, if the bed isn't flat your prints may not stick. Try replacing the bed with a known flat surface. Aluminum tooling plate is cast and milled flat and works well. Beware of fake kapton- one brand new printer that arrived at the Milwaukee Makerspace had a "kapton" covered bed and the prints wouldn't stick to it until the "kapton" it came with was replaced.

If you do everything right you'll be complaining about the difficulty of removing prints from the bed more than about prints not sticking.

Linux replacement for Playon Media server

mark_reh (2015546) writes "I am tired of dealing with Windows and want to go 100% linux. There is one app that I have yet to find a linux replacement for- Playon media server. Is there a roughly equivalent Linux program that makes streaming web content as easily accessible from the TV?

PS3 media server is nice for streaming from my HDD but doesn't have the easy web content accessibility that Playon has."

How are photos controlled on the internet?

mark_reh mark_reh writes  |  more than 2 years ago

mark_reh (2015546) writes "When you search for images via Google Images you see a bunch of pictures, but how is the availability of images controlled? For example, where are all the swimsuit pics of Sarah Palin when she was in beauty contests? How does the Palin organization or any other celebrity, or anyone else for that matter, manage to control availability of images on the web? If such control is possible, how do sex videos of celebrities manage to fall outside that control, or do they?"

men who drive pickup trucks insist on backing them into parking spaces? What is the point?
The bigger the pickup, the more likely it will be backed into a parking space.
If it has a trailer hitch, it will be backed up so the hitch hangs over a sidewalk, just waiting to knee-cap someone walking by.
