Geosync is only 26200 miles... the uncertainty is almost large enough that it could hit a geosync satellite. If only they provided a std deviation or some other probability metric.
Gunshot detection works pretty well. Been unclassified for about 20 years. Been installed in Wash DC for a couple years. The problem is even big brother can't handle merely the volume of gunshots, making these systems thoroughly useless. If there's a cop whom is too close, in other words under fire, it doesn't tell them anything they don't know. If there is a cop close enough to make an arrest, they are already close enough to hear and need to be looking outside for the shooter not in car at a display. And if the cops are too far away to do anything, then it accomplishes nothing.
A conversation monitor would probably be less effective. And less effective than "not much" is very little indeed.
Maybe if you can measure the distance to the listening device, it would be possible to manipulate the frequency of sounds you are making so as to create a standing wave or something that would cause the microphones to be overloaded or to hear nothing
Well, almost obviously, if you knew your location, and the exact location of each mic in the array, you could figure out the distance to each mic. Assuming constant speed of sound you know the time to each mic. So you make 200 or so clicks or pops each timed to saturate all the mics simultaneously. Then it doesn't matter where they're listening, you'll overload them. Works better if you have, say, thousands of click generators. Would probably make the venue sound like a field of crickets unless you happen to be at the focal point.
I wonder if you could do this with mobile phones... do these provide low level access to GPS signals? (For timing and differential location correction.) You might be able to crowd source a distributed recording for reconstruction.
Unless you're using 1980s era analog phones, the voice compression is going to destroy the phase relationships you need, and mask out the low level signals that you'd be adding up.
Also the mics are usually vaguely noise canceling, otherwise think of those dorks whom have cellphone conversations in the bathroom at work, the folks on the other side would hear all kinds of flushing and... stuff. Or maybe they do hear it but just don't care? Always wondered about that.
... so now we have three numbers: 325, 315, 300.... Of course we can assume he rounded there for ease of explaining.
If I were designing a "phased array radar" style microphone, in the front end I'd probably toss the mics that are the furthest away, and of the remaining mics, I'd toss the ones closest to clipping or otherwise distorting. There are also certain combinations of unfavorable geometry both inherently due to mic placement and also the acoustic design.
So its entirely possible they wired up 325 but before they do all the phased array calculations they toss out the 25 worst signals or something like that.
Probably not steel engineering. Very little steel tends to be used on space craft.
Stainless steel is almost stereotypical coolant tubing... Inert and tough as nails and vibration proof compared to all other options. Consider the SSME, admittedly a 30-40 year old engine design, pretty much where ever there is high threat of vibration, you get steel. Injector plate, lots of the engine pipes.
In pure strength to weight, non-ferrous always wins. Much closer race when it comes to strength to volume. But when it comes to vibration survivability, steel almost always wins. Can't beat steel's elastic limit, or at least its really hard to beat.
Would not be surprised to find steel used in the shuttle APU, fuel cell, cryo gasses, and hydraulic systems.
Standard slashdot car analogy, its very "questionable" to make your brake and gas lines out of anything but the toughest steel.
To the unwashed masses, Artificial Intelligence is anything involving feedback (my house thermostat is AI) or anything involving prioritization (welcome to JCL on IBM OS/360 circa 1966).
They are not talking about "real" AI like expert systems or neural nets etc.
This is about support costs, not sales prices, and there are very, very few companies that will provide support for unauthorized copies of their software.
You meant to write:
very, very few companies will provide support for their software
The only "support" I get for any software is free (except my labor) from google.com. I don't need to pay hundreds/thousands for some guy in India to read me a script telling me to wipe the drive and reinstall, which after some decades of experience is all I now expect.
80 million gallons of Blue Lake water will soon be siphoned into the kind of tankers normally reserved for oil
As far as I know a VLCC has never been repurposed for anything, except maybe as an artificial coral reef. So I guess its a first, at this large scale. An interesting engineering / naval architecture angle, which I guess counts as tech, barely.
Assumes a link between inventory management and operations, which probably does not exist at most locations.
Making inventory management easier isn't going to help if there is no link at all between inventory and operations.
Most of the numerous places I've worked at ran inventory on a spares system.. Thou shalt have one spare device at every major POP and datacenter, or the technique used was purchasing depts job was to keep the supply cabinet full of routers.
In fact, I believe it would simply complicate it. Am I wrong?
I believe you are wrong. I joined as an experiment for 6 months. It was a complete waste of time. Burned about as much time as an addiction to at least two weekly tv series, which is quite an investment (in other words I took my trial seriously and worked hard) After 6 months, evaluated my results, which was zilch, and dumped facebook. Frankly, haven't missed it.
At least on slashdot you can learn something occasionally, or get a valuable reference to something new or cool.
I'd be pretty upset if a $75 fee was being enforced via a threat of jailtime.
$1 overdue library book fees are enforced by jailtime. You will be issued a bench warrant if you don't pay your overdue fees. Cops will take you to the station and arrest you. Happened to wife of a friend of mine, and I've read in the papers about this happening to other folks. Some weird bureaucracy thing about its easier to get an arrest warrant than to deal with contracting out to a debt collection agency.
I forgot to pay my taxes on time this year, and when the police who they fund saw my getting mugged they just sat there and let it happen. The fire department is an emergency service, they should not have a "we won't help you" option and their service should not be opt in.
Alternate interpretation, cops are a profit center because they can fine the mugger, so they should always act. Also they can civil forfeiture/steal whatever they want. Firemen can only be a cost center so proactivity is not necessarily required by the beancounters.
Hi facebook pals, especially the kid that ate lunch with me once in the fall semester of 8th grade whom I haven't seen since, you know you are such a special friend to me. Well here we are at Wednesday hump day so I figured all 548 of my facebook friends, especially the ones that live more than 1000 miles away, want to hear that I'm going to eat dinner at McDonalds dollar value meal tonight! Any of you single ladies whom love a big spender, you just feel free to dress up and join me for dinnre. Yea for me. And heres a picture of me drinking a beer in the parking lot so that the crazy prudes in the HR department won't hire me, and/or the cops can cite me for public drunkeness. Isn't technology great? Anyway I'll be sure to post every time I go.. anywhere!
OK my little facebook minions, just posting my status from my IPAD YES MY MY MY IPAD NOT YOURS BECAUSE YOU DON"T HAVE ONE that here I am again at school dropping off the kids. Yes just like every day from the previous month where I posted each and every time. Oh my kids are so cute. You all stay tuned for the next 8 months or so for each time I drop the kids off at school, except for christmas holiday. Oh and by the way here is a completely irrelevant quote from $my_religious_diety or $my_political_party because mine is better than yours and obviously you want to hear all about that!
Hey world, I just typed "apt-get update" on one of my servers. Freaking amazing huh? Especially since I run testing and upgrade about once a week. Well you all stay tuned and I'll let you know next week when I run "apt-get update". Wasn't "Americas next top idol model" just super amazing last night?!! ?? I can't believe he said that to her after she said that to him.
When I read the description, I was picturing an amorphous blob that transformed to your grip.
Smear mouse with sugru, place hand in plastic bag, grip mouse, peel off bag. Personally I use a trackball. Three of them, actually, along with three monitors and one kvm switched keyboard. Well, I guess thats more of a "K" switch than a kvm...
Sugru is, as near as I can tell, carefully marketed epoxy putty. You could probably use generic epoxy putty if you wanted.
They should set things up so that everyone pays, or they get a fine or go to jail. To make that work I guess you'd have to have the government in charge of fire protection, but then they could make sure everyone got it. Then there wouldn't be issues like this.
Another fun issue is the firemen can be better firemen if they're only firemen and not tax clerks.
There is a little old lady at my local city hall that hands me a receipt when I pay my annual property taxes. She's done a great job for ten years. And I know a couple firefighters whom do a pretty good job. Based on my experience, the Venn diagram set of "great firefighters" and "great tax clerks" probably has minimal overlap.
Sooner or later there will be an epic fail where the records are not up to date.
I don't care who you are, that's callous beyond anything I wish to respect.
I agree with you, he should have paid his $75. Sounds like the kind of guy that won't buy a car seat for his infant kids or vet service for his pets "to save money".
You've got to remember, some folks just don't care, and this guys house, junk, and pets wasn't worth $75 to him.
I'm not sure what strategy is most productive to get the guy (and others in similar situation) to pay. Maybe publicizing his story to embarrass him?
The main downside I see to "web-apps" and such is the constant possibility that specific companies will go out of business. With offline apps you can keep using software long after the developer folds
True, but almost infinitely more likely is the dev upgrades the app from version 4 to version 5. Ooops, you have version 5. I guess you need to pay, again.
How many times has my wife bought "discus" the (otherwise excellent) dvd label editor? How many times has she had to buy "garage sale"? Thats the business model to avoid at all costs.

Yet another example of why I am sooooooo glad I don't own a smartphone and won't be buying one soon.
You know how women like those drama tv shows, but discussing the shows bores everyone else to death? Yeah, smartphones are like that.
Life's better when you ignore that whole segment of the marketplace (smartphones, I mean, not women)

The first thing any government will ask is: "So who will be in control of all the world's power?"
This is assuming only one can/will be built. Seems very unlikely.
More likely is major regional ... disagreement. For example, if Israel gets one, where will their neighbors get power?
