Comment Re:I know that happened to me. (Score 2) 361

MP3 players are superior in several ways to smart-phones. I just bought a new one. Sansa Clip+, excellent device, almost unchanged in the last 10 years, just larger memory. Can be clipped to T-shirt or jogging-pants, is entirely unimpressed by being dropped even on a hard floor, very light, long battery life, excellent sound quality.

I use the same player -- it works great with Rockbox

I used to play through my phone and/or computer and then would sometimes forget I was tethered by the headphone cord and walk away and either end up pulling my phone off the desk onto the floor, or dragging my laptop across the desk, knocking stuff off on the floor. The Sansa battery only lasts a couple hours now, so I keep it plugged in with a short USB cable, if yank it with the headphone cord, the USB plug slips out.

I used a bluetooth headset for a while, but got tired of keeping it charged (since keeping it plugged in while in-use doesn't work), with regular headphones I know that every time I plug them in, they are ready to go all day long.

Comment Re:Are they filtering out the pharmaceuticals? (Score 2) 278

Have you considered looking into the concentrations of these hormones and pharmaceuticals you are so concerned about? You don't have to live in fear.

Can you point to the studies showing the levels of these hormones and pharmaceuticals that are present in wastewater treated for reuse as drinking water? Can you point to any regulations that require that water agencies even test for them, and studies showing what a safe level of pharmaceutical ingestion is?

People have lived off of groundwater for many thousands of years and we have a good handle on the effects of consuming minerals (even radioactive elements like radon) in water, but consuming low levels of pharmaceuticals in their water is a relatively new phenomena that as far as I can tell, has not been well studied.

Comment Re:carsickness (Score 1) 435

There will be monitors that can display what's passing by the vehicle outside. The point is, without windows, the structural integrity of the car is increased a whole order of magnitude. We could make crash proof boxes for the passengers.

I don't think it's window failure that kills people in a crash, it's the delta-V of being slowed so suddenly -- the windshield is probably stronger than the lightweight sheet metal that would replace it. Replacing lass with metal might help make a car maginally safer, but I wouldn't expect it to dramatically increase survivability of a crash -- turning the seats around to face backwards would probably contribute far more to survivability (though I doubt that will happen, people don't like to travel backwards, in the train I ride to work the forward facing seats fill up before the backwards facing ones)

Comment Re:The windows need to stay (Score 2) 435

A self-driving car will still need windows in case the human driver ever needs to take over. But the windows could certainly have privacy shades. Other things we'd no longer need for robot cars are street signs, stop lights, and lane markers. You might argue that we'd need to keep those things for the people choosing to drive themselves but my question would be how long should the rest of us finance billions in infrastructure for a diminishing number of holdouts?

Either the infrastructure will need to allow for fallback to human control or not, but it can't be both ways -- you can't expect a human who has let his car drive him around for years to find his way home without street signs, or drive safely without traffic control devices. So if you want to allow for human control, you'll need to provide street signs and traffic signals.

Comment Airplanes and ships have them (Score 1) 435

Airplanes and cruise ships don't *need* windows, yet they are installed at great expense. It'd be a lot easier to build an airliner without having to cut a hundred holes in the fuselage then cover and seal the holes with windows.... yet no one wants to fly in a windowless tube, just like no one will want to ride in a windowless car -- LCD panels and cameras aren't quite the same as a live view through a window.

Comment Re:what about medication? (Score 1) 278

Given that this is already a concern in ordinary municipal supplies, it was the first thing I thought of. I'm glad I'm on a well.

Since some municipalities pump their wastewater back into the ground, being on a well doesn't keep you safe from wastewater contaminants.

And in some areas, untreated fracking water is also pumped back into the ground (presumably deeper than "normal" aquifers, so just hope that the water doesn't percolate upwards (and that you don't need to drill a deeper well to reach water). Oh well, I guess it's better than releasing it into streams like they used to do.

Comment Are they filtering out the pharmaceuticals? (Score 5, Informative) 278

For years there have been reports of trace amounts of drugs in treated wastewater that could be harming wildlife and "no one seems to know which compounds need to be removed or how to remove them from the water safely", so are they filtering out these drugs before reusing the water for drinking water?

Aga said even without knowing exact impacts, consistently seeing antibiotics show up in effluent is concerning.

“Even at low levels you don’t want to have people ingest antibiotics regularly because it will promote resistance,” she said.

It looked at samples from 50 large-size wastewater treatment plants nationwide and tested for 56 drugs including oxycodone, high-blood pressure medications, and over-the-counter drugs like Tylenol and ibuprofen. More than half the samples tested positive for at least 25 of the drugs monitored, the study said. High blood pressure medications appeared in the highest concentrations and most frequently.

Comment Re:Hauling goods is serious business (Score 2) 167

Devil's advocate:

One reason they demand proof of commercial insurance is an obvious one. What happens if they decide to help move, and some glitch on their part strapping down a motorcycle causes it to fall over, then smack the sides of the truck, destroying the other stuff inside?

With most trucking places, you file a claim, call it done. Without insurance, you have to go to court, and may not even get a chance at scoring damages.

There are also commercial licenses in Texas for truck driving. Using a service that doesn't use CDLs may be cheaper... but it is against the law.

The last time I moved, the insurance included with my move was 60 cents per pound - for any coverage beyond that, I had to purchase supplemental coverage. So if they drop your 50 pound $1000 TV, they'll pay you $30.

Comment Re:sampling bias (Score 1) 405

As a member of the younger generation, I feel that the younger generation is whinier and lazier. I feel like half the man that both of my grandfathers were, one who fought in a war I see in movies, was an amazing cook, a skilled gardener, and worked two job back breaking jobs to raise his kids while the other paid his way through university while still finding time to play university football and did his stint in the military. When they wanted to work, they'd knock down doors to get employed while kids these days drop off a resume and consider that job hunting. I could go on and on about how the current day generation pales in comparison to the generations before us but I'm sure it will fall on deaf ears.

I'll agree with you there -- my great grandfather started working in a coal mine when he was 17, fought in a war, smoked every day of his life since he was 16 (with hand rolled cigarettes), maintained a 4 acre yard and large garden, raised (and slaughtered) his own chickens. He spent the last 20 years of his life living alone (his wife died "young" at 60). Up until the last year of his life he maintained he house and yard on his own, reroofed his garage on his own when he was 70 - didn't even tell family he was going to do it, no one knew about it until he was done, he shoveled the coal into his coal fired furnace every winter, he eventually stopped raising chickens after one time when the wolves or coyotes got into the coop and he got tired of patching it. He lived to be 82 years old. He never could get accustomed to those new-fangled remote controls for the TV (back when state of the art was an audio based remote) and walked up to the set to turn it on and off. He still managed to keep ice cream and cookies ready for the grand kids when they visited

Me? I'm too lazy to even cut the grass so I bought a condo with no yard, and the grocery delivers my groceries so I don't even go to the store, let alone slaughter my own meat.

Comment Re:Aren't they called Currents? (Score 2) 61

Generally when talking about water, the definition of a wave specifies it is on the surface:

http://dictionary.reference.com/browse/wave"a disturbance on the surface of a liquid body, as the sea or a lake, in the form of a moving ridge or swell."

If you are using another definition of the word wave (such as that used by physics to refer to light, sound, etc.) when talking about water, you really should specify what you mean.

Given that their paper was published in Nature, they used the correct term for the phenomena.

Internal gravity waves, the subsurface analogue of the familiar surface gravity waves that break on beaches, are ubiquitous in the ocean. Because of their strong vertical and horizontal currents, and the turbulent mixing caused by their breaking....

Comment Re:"It brings density which may be good..." (Score 1) 296

Thank god this is something they seem to realize is NOT the case in TX, and fortunately TX has the space to spare. I, for one, can't f- STAND living all packed in close together like that. I perceive it as some kind of mental illness.

Just don't complain when gas goes up again and all of that space to spare means that you have a 60 mile round trip commute so you're spending $10+/day in gas to get to work.

I live in a dense area (not quite urban, not quite suburban). When I lived 20 miles from the office, I took the train, now I live 3 miles from the office and ride my bike -- I couldn't tell you how much it cost to fill up my car because it was over a month ago.

It could be fixed by simply changing the zoning such that only single-family houses were allowed

This is exactly the sort of crap that leads to urban sprawl, and all the wasted hours on commutes, pollution, oil consumption, etc. We have the same problems in the Bay Area, where SF rejected more than 95% of building permits last year, and 90 minute commutes are routine. If you don't want the sprawl, the only alternative is dense housing in the core city. We need to stand up to the NIMBYs, or even worse, the BANANAs.

A friend inherited a house in SF (Sunset district) that was in pretty poor shape - he looked at the cost and time to get a permit to tear it down and replace it with a 2 unit duplex that would have fit almost within the same footprint of the existing house. He quickly gave on up that due to the cost and no assurance of ever getting his plan approved -- anyone nearby could tie up the planning process nearly indefinitely and he can't really afford to sit on an unoccupied house for a year or more while waiting for planning approval.

Instead he opted to do a nearly down to studs remodel back into a single family house. Everyone in SF complains about the cost of housing, but no one seems to want higher density.
