Loud noises do not cause avalanches. That is an urban myth.
Source: I am an avalanche safety instructor and an avalanche rescue team leader.
Well I have two things to say to that:
1) If loud noises don't cause avalanches, then how come avalanches cause loud noises? and
2) What if a loud noise spooked a herd of alpine goats which then charged over a particularly unstable snow pack, thus triggering an avalanche. Then the loud noise was the cause...
Apologies if joking about avalanches is insensitive given your workplace environment.
He's not looking for a solution just yet. He wants a starting point. You making things too complex too fast. The question is, can you do those things for cheap? Is it possible? If you have a question, the answer is "Ideal conditions"
Silly me. I thought that the poster was seeking to draw on the combined IT and engineering expertise of slashdot, not get information he could easily google for.
agree - this request is too light on content to engineer a solution.
What are the typical and maximum wind speeds in the valleys you are looking at?
How high above sea level are you, and what is the highest point you want the drone to get to?
Are there constraints on noise (ie will a loud engine cause avalanches?
You know, you could have politely pointed out my error like yincrash did above, but chose not to. Now I'm going to have to get medieval on your ass. When dealing with the pain, please remember you brought this on yourself.

I am a fan of the samsung line of android smartphones, but using a high-end smartphone is one of the most expensive options for a wifi router that I've ever heard of.
I don't see many hotels running with that solution.
TPB is infested with torrents that contain malware.
That may or may not be the case, but don't you think it is funny that now that tpb is becoming a legitimate source of music and video from independent artists, corporations with creative industry ties have starting unilaterally blocking tpb without worrying about the law?
I guess they don't mind free advertising, but they HATE competition.
But on a modern PC? Running a variety of programs to handle each individual media type in a manner I prefer for them doesn't present any sort of burden to me or to the system. I have no real reason to stay within the context of a single program that can do-it-all - I just make a new desktop shortcut to my preferred handler of format-X, and bam, I have it always instantly available to me.
XBMC is about the interface. XBMC is all-in-one, and it is nice and remote control friendly. Your solution with desktop shortcuts requires you to have a mouse and a keyboard, and so that solution is a burden to you, even if it isn't a burden to the system.
Not only does XBMC handler MCE remotes correctly out of the box, with the libCEC library it can also handle signals from the remote controls of most television remotes from the libCEC signal which is sent over one of the wires on the HDMI interface. It makes for a much nicer browsing and viewing experience when your pc is connected to a large screen on the other side of your room.
- Conversion from cash to bank account balances often carries a small 'change processing fee' with commercial banks. It's not big; but if you are depositing lots of tiny small change, many banks will charge you for the service. (esp. the other way around - getting cash out as coins, for giving change, etc.)
My bank doesn't charge me deposit or withdrawal fees. If yours does, I suggest you change banks.
- Going to the bank and depositing it regularly is going to cost anyway (salary for time spent, fuel, etc.)
If you have one salaried staff person who works 40 hours a week, and even if they spend an hour going to the bank to make a deposit, then it will cost 2.5% of what you pay them. Since turnover has to be greater than the salary of one of your staff members, it costs far less than 2.5% of turnover to take your money to the bank.
- Loss/theft - it's a lot easier for cash to go missing than it is for electronic payments. (plus costs for security for cash stored on premises)
You really think that loss and theft of cash costs even 1% of everything a typical business makes?
I'd say the above equally match or exceed the 1-2.5% most merchant banks will charge for CC processing services. NFC pricing is generally the same amount. The fees charged by merchant banks for CC facilities are actually completely reasonable - there's some other aspects which hurt a bit more (90 clearance windows, chargebacks/fraud, etc); but the fees are perfectly fine.
I have to disagree. 1% of a business's turnover isn't the same thing as 1% of profit. It is a huge amount. There are several IT stores near my place which have done the numbers, and they all have the same policy - if you pay in cash, you get the listed price, if you pay by credit card, you get a credit surcharge equal to the 1-2.5% the bank charges them.
Even if you dismiss me as an armchair critic - you have to assume that actual retailers know what they are doing.
NIF has always stated that their goal is to do the proof of concept and design so that energy companies can then go out and build similar facilities based on the NIF blueprints.
So the answer to your question is yes, but they have never made a secret about their goals.
However, I would argue that reducing dependence on foreign oil, while also reducing carbon emissions benefits not only all society, but also the entire planet.
Definitely maybe on the teenage part - It is incredibly unlikely that an alien race would mature at the same rate we would - so doubtful that if the aliens are adolescents they would also be teenagers. So not teenage, not mutants, not trained in ancient japanese fighting styles so not ninjas, and not turtles. Just another incredibly naked attempt to leverage an unrelated movie off an existing brand name.
I'd usually suggest we wait for a script or at least actual plot details but this is Bay, the script will just be drawings of things blowing up and pages from a Victoria's Secret catalog.
Screw it, bring on the explosions!!!
Hang on, the explosions are the part you are interested in? I beg to disagree. Bring on the Victoria's Secret models!
The first line in the description of the native X server app is
This application implements a mostly-complete X11 server, running natively in Android. It allows X Window System applications to be run remotely and displayed on an Android device with internet access.
(bolding mine) which is why I assumed most people used it for ssh tunneling.
You may want to run the app remotely rather than NX for many reasons - accessing data or controlling hardware on a remote server for example.
Your point about copying pixels between processes is certainly correct for your use case of a local chrooted OS install. However, for my ssh tunnelling use case, I'm not sure I agree, because the VNC pixel copying and X11 rendering occurs on the remote server, so doesn't cost battery life on the client device - what is sent to the mobile device to be displayed is essentially a partial jpg image. A mouse moving would only cause the pixels effected by that movement to be sent and modified. For this use case - it might be the native x server that uses more cpu - since it has to interpret and render the X11 protocol using a more complex algorithm. It would certainly be borderline as to which technique uses more power on the client device, I think it would depend on the using patterns, and I don't think it can be said that one technique uses more power on the client device in all cases.
Yes I understand the difference between VNC and X11, but for the typical android phone/tablet use case of using wifi x11 tunnelling over ssh to a remote server running X apps, none of the performance issues you mention (hardware acceleration, video streaming) are relevant at all.
Both the "native" X11 server and the "fake" X11 in a VNC session will have essentially the same performance it that situation.
This is the same guy who wrote the partially completed android X11 server that was posted on/. recently. I didn't see the story there either. I mean, it was impressive that he had implemented most of X11 by himself, but a fully featured x11 app already existed on the market ( here), so I don't consider it newsworthy.
Well, in Australia, they only have taxes on internet purchases greater than $1000.
The reason being that when the tax office actually crunched the numbers, they found that collecting such a tax would cost more than it brought in.
Looking at the global situation, I guess it was a rare flash of honesty, most government departments generally leap at the chance to increase their budgets and hire more staff.
At the moment, I am self-taught and can easily keep up in a conversation of computer science majors.
Talking is not the same thing as doing. I can hold my own in a conversation about playing a piano, but I can't build one, and I can't can't play rachmaninoff's piano concerto no 3.
One of the double-edged features of computers, coding and modern IDEs is that anyone can sit down and write a program, and have it work. This is good in one sense- it SHOULD be easy for people to use computers as a tool to do whatever they want.
But it is bad in the sense that self-taught developers have all sorts of bad habits, that they generally don't even know are bad.
Techniques and concepts for building modular, maintainable and scalable code are important (even if the words themselves have been used so often by bad management that they have almost lost all meaning), and are typically missed by self-taught programmers who are more interested in getting the program to work than worrying about the architecture.
Having said that - quite a few of the IT and CS courses floating around are so bad that you are better off not doing them. But if you can find a good course, I seriously recommend doing it.

Walking around aimlessly in the rain is unusual behavior unless you're a little kid splashing in puddles or a duck.
But I like long walks in the rain!

Well Facebook only breaches your privacy when a company pays for the service. They have no desire to give that info out for free.
Obligatory James Houston's cover of Radiohead's Nude: http://www.youtube.com/watch?v=pmfHHLfbjNQ Serious worth a listen.
Currently internal SATA3 one terabyte drives are less than $100, so yeah - on a $2500 computer it doesn't look like much storage.
Now if it was 20 years ago, I might agree with you.
Hey Bad Astronomer, do you think this has a chance of being a big enough explosion for the LIGA gravity wave interferometers to detect?
Actually it does. Here's how:
- Conversion from cash to bank account balances often carries a small 'change processing fee' with commercial banks. It's not big; but if you are depositing lots of tiny small change, many banks will charge you for the service. (esp. the other way around - getting cash out as coins, for giving change, etc.)

Even if you dismiss me as an armchair critic - you have to assume that actual retailers know what they are doing.
It also doesn't charge either yourself or the merchant a 1 - 5% transaction fee every time you use it.

Maybe Stephen Conroy can win internet villain of the year a second time.

Whistleblowers and muckrakers shouldn't be a part of the government.
Quis custodiet ipsos custodes and all that rot.
Dude - Maxine Mckew winning Bennelong off John Howard was one of the sweetest moments in Australian politics.
In case you've already forgotten - she also was a journalist, and has definitely been a muckracker and whistlebower in her time at the ABC.
Actually - you can already buy nano dip-pen arrays commercially that can be used for this sort of manufacture.
Basically they are arrays of thousands of atomic force microscopy micro-cantilever tips which can be used to manipulate at the nano-scale.
So there is fab technology which is already heading in this direction.
I guess someone accidentally bought too many votes this time.
