Comment Re:In all seriousness.. (Score 1) 397

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.

Comment Re:Porn browsing? (Score 1) 415

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.

Comment I use the scope as a logic analyzer (Score 1) 215

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.

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.

Comment yay for pre-emptive flood prep (Score 1) 85

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.)

Comment Re:Sugar (Score 1) 926

lol

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"
Sheesh.

I think it's the 'lol' that particularly annoys me when people say things that are just flat-out wrong.

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.

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.

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.

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.

I really want to build a laser mosquito zapper (like this one: http://spectrum.ieee.org/consumer-electronics/gadgets/backyard-star-wars). However, this looks pretty pricey (multiple cameras and galvanometers).

If the expense/time is a bit daunting, mosquitoes are attracted to heat, so some incandescent bulbs in front of a fan, with a mesh bag behind it, will scoop them out of the air (along with lots of other insects.) I had a friend with one of these and she collected something like a pound of insects per night.
With that said, I don't think either one is going to make a dent in your local mosquito population unless you had two dozen of them running nonstop. Getting rid of stagnant water in your neighborhood will do far more than any amount of adult mosquito hunting.

Amusingly, when someone actually attempted to track down who murphy was, and where the law came from.... http://en.wikipedia.org/wiki/Murphys_law

Edward Murphy proposed using electronic strain gauges attached to the restraining clamps of Stapp's harness to measure the force exerted on them by his rapid deceleration. Murphy was engaged in supporting similar research using high speed centrifuges to generate g-forces. Murphy's assistant wired the harness, and a trial was run using a chimpanzee.

The sensors provided a zero reading; however, it became apparent that they had been installed incorrectly, with each sensor wired backwards. It was at this point that a disgusted Murphy made his pronouncement

So this is potentially, very much related to the original usage.

If I remember right, the way a wheatstone strain gauge is set up, there are four ways to connect it. One is right, two are wrong but give you half the resolution you expected -- so you get data, just lousy data -- and one is completely wrong and you get no data whatsoever. It was hooked up in the completely wrong configuration. That was what made him so mad: there was only a 25% chance it would get hooked up in the completely worthless configuration, but that's what happened.

You'd be better off trying to get Shakesphere out of schools for his anti-Jewish views - those *did* get expressed in his plays.

Slashdot isn't the place for a deep discussion of Shakespeare, but I'm going to, anyway. It's arguable (and is regularly argued) that Shakespeare was not actually anti-Semitic. Shylock is portrayed as a villain, it's true, but his speech, "I am a Jew. Hath not a Jew eyes? Hath not a Jew hands, organs, dimensions, senses, affections, passions; fed with the same food, hurt with the same weapons, subject to the same diseases, healed by the same means, warmed and cooled by the same winter and summer as a Christian is?" shows him (at least in that passage) as a sympathetic human, not a villain, and more generally, the rest of the speech, where he declares that he'll act just as horribly as his persecutors do (and proceeds to do so, driving the play) can be seen as a character's reaction to a bigoted society, rather than of the author's hatred of Jews. Shakespeare had some outright villains who did evil just to do evil, but generally his worst characters (and I'm thinking of Iago and Shylock specifically) had excellent, rational motivations for doing the evil things they did. His writing of them was not based on hatred of their races, but on how society had shaped them into tools for evil.
