How I might do it: use a laser. Shine it on something light (and probably reflective) that's suspended in the air or hinged. Problems would be blocking wind currents without blocking the sound.
"MapReduce is a programming model and an associated implementation for processing and generating large data sets. Users specify a map function that processes a key/value pair to generate a set of intermediate key/value pairs, and a reduce function that merges all intermediate values associated with the same intermediate key. Many real world tasks are expressible in this model, as shown in the paper.
Programs written in this functional style are automatically parallelized and executed on a large cluster of commodity machines. The run-time system takes care of the details of partitioning the input data, scheduling the program's execution across a set of machines, handling machine failures, and managing the required inter-machine communication. This allows programmers without any experience with parallel and distributed systems to easily utilize the resources of a large distributed system."
"Their target audience doesn't want to see realism, or even something down to earth. They want to see love stories where a poor person is escalated into another caste because their lover (not in the literal sense) is wealthy. They want to see 20 exotic locations that they will never get to physically visit, all compressed into a single movie, even though there is no reason whatsoever within the plot or storyline to visit 20 different locations"
Y'know, I'm not a impoverished Indian villager, but I don't want pay money to see day to day stuff either.
Why should I pay money to see dark movies about the bad guy winning, or stupid violence when I could just turn on the TV and watch the news.
And if I wanted cynicism, there's plenty of it nowadays for free.
Say all you like about movies like "Finding Nemo" but those do make money, it makes me wonder why Hollywood makes the usual movies they do - if they're really interested in profit. Do they have some sort of agenda or something?
At least Bollywood is making what their target audience wants (or will at least settle for). Whereas just look at this year's lack lustre stuff from Hollywood.
Movies made by heartless accountants or executives or committees?
Seems almost like either there has to be some Emperor's New Clothes syndrome somewhere (Yes sir, the movie will be a hit), or they are intentionally doing this.
BTW I heard an Indian friend of a close relative said that his parents wanted his significant other to be slim, fair skinned, have reasonably straight hair, so he muttered something in the line of "sounds like a chinese girl".
The detection range from the active transmitter you talk about is only applicable if the sound has to return all the way to the transmitter. The listeners don't have to be in the same spot as the transmitters, and the listeners don't all have to be in the same spots as each other too.
And why shouldn't you know the range of a ping, especially if the source of the ping is friendly AND stationary? Even if the thermoclines change with the seasons, I'm sure there are many measures that one can take to cope with those. After all, friendly pings could be modulated or constructed to carry information to help listeners figure some tricky things out. Plus listeners would know the original forms and possible locations of all the friendly pings (not sure if spoofing might be a problem, but I think we're far from that at the moment).
Why would it be useless if enemies avoid fixed active arrays? If they do avoid the arrays, it means you already have some influence over the enemy already. At least you'd know how many super quiet subs there are in certain areas. It may be useless for direct offense. But direct offense isn't the main thing most countries get up to.
Of course there are only very very few countries with extremely quiet subs. Maybe just 1;). That country is probably able to detect subs from other countries using existing other methods.
Anyway such systems might not so good for marine life - they could probably be designed to blast even louder than the combined/effective 230+dB that the SURTASS + LFA does. So perhaps they won't be such a good thing to have - even more sound pollution...
Lastly, yes I've zero years of experience in the systems you talk about.
I was never talking about submarines being the source of sonar.
You'll know where the "ping" is coming from if it's from a fixed active array. And it should be possible to use the "shadow" effect.
As you pointed out the loud sounds are used because of transmission losses. So if you want a submarine to use sound from a fixed active array, the fixed active array has to send an even louder sounds.
Close your eyes. Clap your hands. From the sound reflections you can tell the rough size and sometimes even the shape of the room. Now get _someone_else_ to clap his/her hands in the room you are in, about the same effect (you still get info about the room), plus you know exactly where that person is now. Next get someone to walk between you and the clapper, and you'd be able to detect that someone (this even works with ambient noise).
I suggest that "ping stealing" can work well. If current technology can't do that, then it means it isn't good enough, not that it isn't possible.
And you don't have to steal pings if a fixed station on the ocean willingly loans them to you - even arranging for the pings to be done in a certain way so that you can get the most out of them.
If they managed to wire up a dolphin or bat to some sonar system they'd probably be able to do a lot more.
But maybe the very best acoustic analysts might be good enough? Can they tell the difference in sound _reflections_ from boat and figure out whether it's made of wood or steel?
Probably could start some kids young, getting them to interpret slowed down reflected chirps, and sped up noises.
I call BS on quantum immortality. I don't see why one should rule out the scenario that due to your (or other) actions, you end up dead or nonexistent in all possible universes.
As for eternal life. Eternity is a very long time. We are all flawed. Flawed creatures living for eternity could be a definition of "Hell".
"If they did something you didn't know about or didn't authorise that would not be considered reasonable, then they wear it."
That's the whole point of outsourcing blame;).
In fact, I believe in some places you can pay people to be the boss of the company and go to jail for you. They get a retainer whilst they aren't in jail, and when they are in jail their family gets double the retainer.
Of course, there are a fair amount of risks involved with that approach.;)
Of course it'll work. It's already been done successfully before.
Now is it going to be significantly better or an actual advance? Sure doesn't look like it.
Whereas while I'm not sure a space elevator would be buildable, if it actually works it'll be a significant advance.
The past 20 years in aerospace have been rather disappointing.
Contrast: 1969: Concorde, Jumbo Jet, Man on moon, etc. 2005: Low earth orbits with flaky manned spacecraft, plus talking about redoing stuff already done 30 years ago.
Seems almost like going backwards into the Dark ages from the Roman Empire.
What if a monkey owned by a 3rd party did it without your authorization?
Also, I'm near certain that in many countries you should be able to outsource the legal problems to someone in a different country - where perhaps those legal problems don't even apply.
e.g. If someone else "bought" and installed the software, and you entered a contract to rent the use of the software from them. Much like using a PC in a cybercafe, except the PC is in your home.
I mean if MS et all want DRM and rights to your hardware, you might as well sign off some rights to someone else, who might actually prove to be more on your side than them;).
" Whenever someone gets off even though they committed the crime, that is unjust,"
You miss a significant point. Not all laws are just.
Say the defendant did break the law, but if the jury acquits because they think the law is unjust, is that really injustice?
After all, remember who makes those laws - fallible people. Nowadays all too often it's the corporations and fat cats, through legislators they influence.
If one can't trust the jury's judgement in general, then one should do away with juries totally.
Slashdot Mirror
They? You totally miss the main point: the people detained are really going to hate it.
And if people have 500GB of data, or more, does that mean the police are going to want to detain them for even longer?
There are already 500GB drives out there.
It seems stupid to me that insert would have a different format from update.
e.g. (field1,field2,field3) values ('1','2','blah') vs field1='1', field2='2', field3='blah'. Kinda dumb.
Plus why wasn't there a command to "merge/replace/put" rows into a table much earlier?
SQL's badly designed, but looks like we'll have to live with it for decades to come.

By nonconstitutional I meant laws that were not part of the Constitution.
Non as in "Not belonging", vs un as in "Negative".
Similar to the difference between non-American and un-American.
Heh, is that how you figured out that the mouse was female? ;)
" But there are occasionally some meaningful movies, which make it to international film festivals"
But which make the most money?
I'm just wondering. Is the film industry in India in touch with their audience?
I'm not sure what the film industry in the US is up to...
"Their target audience doesn't want to see realism, or even something down to earth. They want to see love stories where a poor person is escalated into another caste because their lover (not in the literal sense) is wealthy. They want to see 20 exotic locations that they will never get to physically visit, all compressed into a single movie, even though there is no reason whatsoever within the plot or storyline to visit 20 different locations"

"if the laws are so voluminous that they cannot be read, or so incoherent that they cannot be understood; ".
Most nonconstitutional laws should have a limited lifespan. Especially the civil ones.
That way lawmakers will have to continuously and intentionally keep crappy laws alive.
The longer you want a law's lifespan, the more people you need to pass it.
Maybe I'm too used to monitors set to 85Hz and games at > 60fps, but 24 fps is a really crappy framerate.
I especially noticed the crappy framerate in the LOtR scenery pans- maybe because it was digitally rendered and nonmotion blurred?
Anyway, it wasn't just LOtR, you can see that flicker/ripple thing in the cinema all the time.
Filming in film is also crappy for low light shooting, unless you really want a particular effect.
Foo is also a Chinese surname.
;).
BTW I heard an Indian friend of a close relative said that his parents wanted his significant other to be slim, fair skinned, have reasonably straight hair, so he muttered something in the line of "sounds like a chinese girl".
I'm not sure what his parents response was...
"So far, the art of modifying a person's genetic makeup is in its infancy"
You know what's the main problem with gene modification and germline modification?
Scenario A: You can't have kids, because Corp M says it's unauthorized reproduction of their intellectual property.
Hopefully that will be fixed soon. But a world with Scenario A sure looks more likely than things being fixed.
Apparently many Slashdotters are "quarantined" from AIDS.
But if you're going to use energy to make a fuel as a "energy transportation medium", why not spend it on making suitable hydrocarbons?
There's lots of existing infrastructure and tech for transporting and using hydrocarbons.
It's still a net zero CO2 generation if you take CO2 from the air to make the hydrocarbons.
What we'd need are decent hydrocarbon fuel cells.
I never denied that you know a lot.

There are different sorts of sonar. How powerful were the ones your ships were using? Levels > 160dB can kill many things.
Lots of people talk about submarines not using active sonar.
While I am not a sub/military/sonar guy, I think that submarines can use active sonar pulses from fixed sonar arrays.
This way submarines can use "active sonar" without being a source of the sound themselves. There are so many possible ways to use that sort of thing.

Anyway, can those apps work with Postgresql? There are some tools and howtos to port some stuff from Oracle to Postgresql.
Not everything can be ported easily though.
