The Next Keurig Will Make Your Coffee With a Dash of "DRM"
My guess RFID. By one regular pod, cut RFID chip out of it, tape to the bottom of subsequent generic pods.
FWIW we tried that with our Stratasys 3d printer. It remembered the RFID number and remembered that the print cartridge was out of print material, so sticking the rfid tag to a new, third-party, 1/4 the price, filled to the brim container of print material did precisely nothing for us. I have no idea if the keurig will do the same. Oh, it was also a pain in the butt because they'd built it into the side of the cartridge, so when we cut it out it wouldn't simply stick on the new cartridge as it had a flat side and the resultant cartridge+rfid tag wouldn't fit in the printer, so we had to bodge something up by putting it on the front where the door closed and hoping it would be detected. It was, but see above.
California Fights Drought With Data and Psychology, Yielding 5% Usage Reduction
Why not simply lower the water pressure by 10% to curb water usage?
I dunno about everywhere else, but where I live -- next door to the local water tower -- there isn't any sort of water pressure regulation mechanism. You pump water into the water tower, and it flows by gravity to all the houses that are lower than it. And, in the summer, when everyone down in the valley is running their sprinklers, my water pressure is low enough it's difficult to take a shower, so even if you did manage to regulate pressure it would have a disproportionately large effect on some of the people and very little on some others.
3-D Printed Pelvis Holding Up After 3 Years
This is purely anecdotal, but the two indie framemakers I know who have worked with 3d printed lugs have both said the lugs broke very quickly and they only used them for prototypes, didn't consider them safe to ride. One said he thought he could make a 3d printed lug (this was stainless steel, through shapeways, silver-soldered to Reynolds SS tubing) that would be durable but he guessed it would weigh about 4x as much as equivalent forged columbus lugs.
Edward Snowden and the Death of Nuance
It's the same as how Congress's approval rate is extremely low, yet in the last election most seats didn't change hands. In both cases, people are saying "everyone else is the problem, not me!" -- they said "vote out your incumbents" but still voted for their incumbents claiming their incumbent isn't the problem.
What makes this complicated is that I think that's a reflection of America. My congressman _is_ a really good representative for me: he's a smart gay liberal who has started several successful tech companies. I vote for him because he's doing stuff I like. My aunt's congressman is a good representative for her: a pro-life, pro-gun conservative creationist pastor. She votes for him because he's doing stuff she likes.
We'd like to think that there's a logical disconnect between "congress is crazy" and "my congress person is awesome" but that's not necessarily true: we, as a country, have an extremely wide spectrum of opinion. Jim Hightower used to say there's nothing in the middle of the road but yellow stripes and dead armadillos. If congress is a dead armadillo, midway between what I want them to be and my aunt wants them to be, my aunt and I can both be contemptuous of congress while liking our personal representatives, and both of us can be logically consistent in doing so.
20% of Neanderthal Genome Survives In Humans
Lactose intolerance is complex. The Tuareg of Saharan Africa have lower lactose intolerance rates than Finnish people, for instance. It mostly has to do with whether a group has spent a long time as nomadic herders or not, and adult persistence of lactase activity appears to be caused by several different mutations, that arose spontaneously. http://s1.zetaboards.com/anthr... has a nice list of adult lactase activity in different ethnic groups.
Device Mines Precious Phosphorus From Sewage
There was a fairly interesting Radiolab podcast about a program that shipped New York City's biosolids to Colorado for use as fertilizer: http://www.radiolab.org/story/...
It includes a significant discussion of waste treatment, pathogens, and the economics of shipping what some municipalities call hazardous waste cross-country.
Electrical Engineering Lost 35,000 Jobs Last Year In the US
Pure speculation, but it could very well be a knock-on effect from off-shoring manufacturing. You want at least some of your engineers to be close to the manufacturing line to debug when things go wrong. The designers might stay in the US, but manufacturing, test, packaging, etc., will shift towards the factories. And then, some years later, you'll want the designers to be near the mfg/tst/pkg guys to allow easier communication.
It's exactly this. You want your chip designers to be working right next to the mask layout people because layout needs designers to correctly optimize the layout. You want your test people to be able to walk through the whole test program design with the designers, who will be involved throughout the test hardware and program design, because test engineers know how testers work, and designers know how the chip works, and matching those is tricky. And you don't really want to be shipping tested wafers overseas for packaging and then waiting for them to come back to test packaged parts, and the product engineers need tester access and parts access to characterize the parts and produce the datasheet info, so at that point you have the whole silicon design team, from conception to finished parts, in one place. It can be done remotely but with a significant time adder or lots of evening/midnight phone meetings. It's easier to separate applications and project engineering from the design/manufacture group, but there's still some value in having them colocated. At that point, all that's left is middle management... and that's even easier to outsource.

Amazon Reveals "Prime Air", Their Plans For 30-minute Deliveries By Drone
If private organizations can't use drones to help with natural disasters, such as those in Colorado, how do you suppose this will get approved to fly near local airports and various cities and towns won't outlaw the flying of drones?
Of course, there's always the question: How do you deliver to high-rise apartments and other high-density dwellings?
During the Colorado flood, the area around it was under temporary flight restrictions, as determined by the FAA, and no unauthorized aircraft were allowed to fly in it.
While TFR's are getting vastly more common as every penny-ante promoter wants to make every event seem so big it needs special FAA protection to allow it to run, the reality is that 99% of the time, 99% of the airspace is available for private and commercial air operations.
NSA Planned To Discredit Radicals Based On Web-Browsing Habits
If anything, I'd mistrust the people who make a big deal about never looking at internet porn. Just look at the frequent revelations involving vocal evangelists.
In general, I've come to the conclusion the louder someone screeches about the morality of other people, the higher the likelihood they'll get caught in a scandal.
Which has more or less confirmed for me that people are lying douchebags, who mostly want to point the finger at everyone else.
The more rigid and extreme the position, the more they're full of shit.
While I entirely agree with your position, something to consider is that there is a logically consistent stance embedded in there. If you believe that everyone is a sinner and should try to reduce the amount that they sin, then it's consistent to sin while being vocally opposed to sinning: the person may regret the behavior and pray for forgiveness and all those other weird things people to do try to make themselves feel better about natural impulses that their churches have told them are bad. I think that situation is practically universal among evangelical religious types of most religions. They're all trying to force themselves and everyone else to hold high standards of living, and while failures to do so are inevitable they're still bad.
Ask Slashdot: What's On Your Hardware Lab Bench?
Sure it doesn't do what a good logic analyzer does, but it's fast. Current project: trying to get an Ohaus digital scale's RS232 output talking via an FTDI serial-to-usb to my computer. Scope-to-computer works great. Computer-to-scope doesn't work at all. Hook up probes to the TX and RX lines and I can immediately see that something's going from minicom to the Ohaus, and the voltage is roughly what I'd expect. On RS232 that's a serious question, and one that most of the usb logic analyzers I've worked with don't address: is the voltage high enough to trigger something that may be expecting 12 volts?
And I'd like to see what it's actually sending. Hit the trigger button and type something in, and there it is on the screen. Save it, type in something else, overlay them. Hey, the FTDI is stripping off the terminal linefeed! That's good to know, given that the Ohaus absolutely requires CR,LF.
That took me about thirty seconds with a scope. It'd take me longer to start up the USB logic analyzer program and get it set up.
NYC's 250,000 Street Lights To Be Replaced With LEDs By 2017
Another advantage, if purchasers care to implement it, is that you can have somewhat intelligent LED lights that dim down to 30% when there's no traffic around, so it's still light, but much lower power, then run back up when traffic is a block away. It doesn't add much to the system cost to add motion detection and communication with nearby lights, particularly since some industrial/commercial LED lights are adding selftest health/failure reporting already.
Boulder's Tech Workers Cope With Historic Flood
I work in south Longmont. Where I cross the Boulder Creek, it's usually 3 meters wide and so shallow the rocks on the bottom emerge from the surface of the water. When I was hauling out yesterday after our workplace got an evacuation notice, the creek was a kilometer wide, backed up against the bridge, which is probably 15 meters wide by two meters deep.
Longmont spent eighteen months reworking the Lefthand Creek drainage, deepening it and tearing out all the trees beside it, through the middle of the city. At the time, local citizens were outraged at the expense, writing nasty letters to the newspaper and showing up at city council meetings yelling about what a waste of money it was and how debit spending was the devil. Lefthand filled right up to the top and moved like a freight train, but didn't overtop through much of the town. The place where they stopped the rework, and the creek returns to its shallow, cottonwood-tree-filled drainage, is where it spread out and started flooding basements, according to pictures my friends who live there are sending me. I'm hoping this experience will motivate the city of Boulder to do the same for Boulder Creek. One of my friends lived in a house across from Naropa University, right beside Boulder Creek, that had a big metal sign on the front warning the inhabitants that they lived in a flood zone. That should never happen. That should be parkland, not places where kids live. (She moved, thankfully, because that house had close to two meters of water in the main floor, from pictures I've seen, and I'd hate for her and her two toddlers to still be living there.)

What's Causing the Rise In Obesity? Everything.
fructose is just a disaccharide, its technically a more complex carb chain than glucose (monosaccharide). do you mean high fructose corn syrup? you're sort of right. typically what you see is HFCS55 which is 55% fructose and 41% glucose. to put it in perspective, granulated sugar is 50/50 fructose/glucose. so HFCS is only marginally more fructose than regular sugar, so you're wrong. but you're also right, because sugar, hfcs and all the other high glycemic carbs are what's really causing this problem.
LOL indeed. Fructose is a monosaccharide: http://en.wikipedia.org/wiki/Fructose "Fructose, or fruit sugar, is a simple monosaccharide" just like glucose. They're isomers of each other. Sucrose is a disaccharide, consisting of a glucose and a fructose, 50% of each. http://en.wikipedia.org/wiki/Sucrose "The molecule is a disaccharide composed of the monosaccharides glucose and fructose"
I think it's the 'lol' that particularly annoys me when people say things that are just flat-out wrong.
Could Humanity Really Build 'Elysium'?
Just wondering: are 150 years projects viable at all? Is there any example of such an enterprise? What's the incentive for human beings to take part in thigs they won't see the results of?

Building a Full-Auto Gauss Gun
Sorry about the delay in replying. Those are some pretty awesome caps for railgun/coilgun/quartershrinker applications. High voltage, high amperage capability. If you decide to play with this, bolt a 1 meg resistor across the cap leads and leave it there all the time that they're not actually installed in working equipment, because this stuff could kill you with a discharge. So, yeah, rated voltage and, if they list it, equivalent series resistance, which is a measure of how quickly it can discharge, and you'd like as small as possible.
Building a Full-Auto Gauss Gun
This kind of gauss weapon is not new. The big limitation is power.
If you're the U.S. Navy, with a nuclear power plant aboard your aircraft carrier, a railgun is easy to power:
A rifle? Catch Doc Brown next time he stops over in 2013. Maybe he has an extra Mr. Fusion to spare.
If you throw that in a backpack, maybe you can power your handheld rifle for a few shots.
Couldn't BFC's (Big Fucking Capacitors) be used to store charges? Like the kind you would get from a car stereo dealer?
Can anyone explain why they would/wouldn't work? I'm fairly newbish when it comes to the intricacies of electronics, and trying my best to develop a healthy understanding.
A non-inclusive answer is that the energy stored in a capacitor rises with the square of the voltage, so what you want for really high energy density is very high voltage caps. But, along with that, when you discharge them, you're relying on an extremely quick discharge so you get huge amounts of amperage out of them (discharge current = voltage / time) so you also need massive current-carrying capability for the plates and wiring. That means fairly specialized capacitors.
What's Stopping Us From Eating Insects?
A horse can do a large amount of work, they are more useful on the yoke than on the table. Same with dog. Dogs are more useful as a work animal than a food animal. Cows, not so much. I can't think of too many situations where a cow would be best suited as a work animal.
Until the invention of the yoke, in about 400 AD, and its propagation to Europe in about 1000 AD, horses were nearly useless as draft animals. They're still less useful for ploughing and cart-pulling than oxen are in hot parasite-ridden countries because they're more delicate.
The City Where People Are Afraid To Breathe
Most of the medical professionals and vetrinarians in my area of southwest Utah know about it.
It's no secret.
People gotta live somewhere. Fires, floods, earthquakes, malaria, congressmen, natural radiation, natural heavy metals in ground water... every place has some problem.
It isn't like we are talking about bubonic plague running rampant. What should the government do? Spray bleach over everything? Kick people off their own property?
Funny you mention that: the bubonic plague is endemic throughout the American southwest and there are reported cases in people every year. Prairie dogs, among other rodents, carry it. (Most common cause of infection is outdoor cats getting plague-infected fleas that have left dead prairie dogs, then bringing the disease home to their owners.)
And as for the where-should-we-live, I made a map of natural disasters in the US a while ago when people were on about how anyone would be dumb enough to live in Norman, Oklahoma. Between hurricanes, tornadoes, earthquakes, tidal waves, forest fires, flash floods, bubonic plague, volcanoes, and a couple of other things, the only place I've found that looks fairly safe in the entire US is somewhat east of Pocatello, Idaho.
