110,719 | it is said that Morgoth will destroy the Sun and Moon in the Prophecy of Mandos:
**"Thus spoke Mandos in prophecy, when the Valar sat in judgement in Valinor and the rumour of his word was whispered among all the Elves of the West. When the world is old and the Powers grow weary, then Morgoth, seeing that the guard sleepeth, shall come back through the Door of the Night out of the Timeless Void; and he shall blacken the Sun and the Moon."**
is there anything in the History of Middle Earth that would indicate a plan of doing this or is it just a factoid of a Judgement Day predestined? | 2015/12/16 | [

When the world is old and the Powers grow weary, then Morgoth, seeing that the guard sleepeth, shall come back through the Door of the Night out of the Timeless Void; and he shall blacken the Sun and the Moon. But Eärendil shall descend upon him as a white and searing flame and drive him from the airs. Then shall the Last Battle be gathered on the fields of Valinor. In that day, Tulkas shall strive with Morgoth, and on his right hand shall be Eönwë, and on his left Túrin Turambar, son of Húrin, coming from the halls of Mandos; and the black sword of Túrin shall deal unto Morgoth his death and final end; and so shall the Children of Húrin and all fallen Men be avenged.

The best I could find regarding the mechanism:
>
> According to the prophecy, Morgoth will discover how to break the Door of Night, and will blacken the Sun and the Moon. For the love of these, Eärendil will return from the sky and shall meet Tulkas, Manwë, Eönwë (with the old version of his name Fionwe) and Túrin Turambar on the plains of Valinor.

>
> There the forces of the Valar shall fight against Melkor and The Dark Powers. Tulkas will wrestle with Morgoth, but it will be by the hand of Túrin that finally death and destruction will be dealt to Melkor.

Break the door of Night and Blacken the Sun... But a battle will ensue meaning I think it's the effect of this combat (terrible war) that will blot out the Sun and Moon. Smoke, fire etc. will have that effect both at night and day.
Of note is that the prophesy itself is brought into question:
>
> It must be mentioned here that "Dagor Dagorath", the name properly said, was not used by Tolkien in *The Lost Road* or in *The Shaping of Middle-earth*. All the occurrences of the term in these books were in the editorial notes of his son. The canonical mentions of the name are only in *Unfinished Tales*. Christopher Tolkien included the name in *The Shaping of Middle-earth* because the first mention of the Second Prophecy of Mandos was placed there but Tolkien did not mention the existence of a Prophecy in the text published in *Unfinished Tales*. The manner with which the name appears in *Unfinished Tales* suggests that there are some kind of "foretelling" of The End but does not state that it comes from one of Mandos' prophecies.[source](https://en.wikipedia.org/wiki/Dagor_Dagorath)

> | The second prophecy of Mandos was written during the phase where Tolkien had the sun and moon as bright fruit from the two trees carried around Arda in vessels by the maiar. |

However by law all US airlines must allow you to either cancel a ticket up to 24 hours after purchase for a full refund, OR hold a ticket for up to 24 hours before purchasing it. (Most airlines do the former, but they are allowed do one or the other).
Thus your best option will be to buy one of the tickets, and then buy the second immediately afterwards.

Thus, two separate reservations will be needed.
There are two ways to approach getting adjacent seats with separate itineraries. The first is for one of the travelers to make both reservations, one immediately after the other. First, select a seat on the B > A flight with an adjacent empty seat. Then, when booking the second itinerary for the other travelers, select that adjacent seat. This could be done either through an online portal or aggregator, or directly through the airline.
Sometimes unsold seats are shown as "unavailable" because they've been allocated by the carrier to its code-share partners. The best shot to secure adjacent seats is by booking both itineraries at the same time with the same portal, or aggregator, or code-share partner, or carrier.
A second tactic is to buy separately, but in coordination. My wife and I have successfully done this many times. We sit at adjacent desks in our home office (and have also done it by phone or message when we're apart), book concurrently using the same source, select adjacent seats, and press "buy" at the same time. |

Hi!
I'm a beginner in this and I'm having some troubles while sculpting which is after joining two meshes the color changes.

But the thing is it seems it doesn't work anymore, or at least I did it badly.
Besides, I don't know where's the option "normals" to then click recalculate outside, I only could find the shortkey (ctrl+n for recalculate outside) but again, it didn't work.

From reading through the section titled "Cultural Changes to Get a Space Truck", I think that the main point of the term "space truck" is to emphasize that it doesn't really matter how pretty or elegant the final design is, it only matters how much it costs to get the payload into orbit.
For non-engineers this sounds completely obvious, but it goes completely against the grain for many engineers. "Elegant" design (where the exact criteria for what is elegant varies from discipline to discipline) is considered particularly beautiful and is often striven for at the expense of other concerns. (Yes, I have been guilty of this) Mostly, this is a matter of culture (simple, robust design is rarely stressed, either in training or practice) and egotism (engineers like to brag about the beauty of their designs). | Source: <http://www.projectrho.com/public_html/rocket/surfaceorbit.php>

32,663 | When electronics/computer companies design a new chip, processor/ memory card/ or a solar cell, do they study the effect of cosmic rays on such electronically sensitive materials? If not, why not? | 2012/07/23 | [
"https://physics.stackexchange.com/questions/32663",
"https://physics.stackexchange.com",
"https://physics.stackexchange.com/users/4521/"
] | Cosmic rays do have noticeable affect on electronics. The most prevalent effect is from memory bit flips (known as "soft errors").
The degree of significance of the effect depends on the application. A typical soft error rate for static RAM is in the region of 400 FITs/Mbit [1]. (Failures in time=failures per billion device hours) So if you have 1 Gb of memory per chip and 1000 chips, then expect 0.4 flips every hour. This is precisely the reason that a lot of applications require ECC on their memories.
[1] footnotes: Part of the rate is from alpha particles from decay of materials of or near the chip (this is the smaller of the two major components). Also, the rate is quite a lot higher for DRAMs, which is why DIMMs with ECC exist.
Soft error rates are quoted at sea-level because the effect of being closer to space is non-trivial; which is pretty much proof right there that the effect is from cosmic rays.
There are effects on logic gates too, but this is *usually* not worked around for two reasons. (1) It is very difficult and/or expensive to do, however there is much research into redundant/fault tolerance circuits (2) when a bit flip occurs on a combinational path, it would have to coincide with exactly when the output of the path is observed (e.g. at a flipflop) which reduces the observability of the effect.
Finally, there is an effect known as single event latchup (SEL).

] | Portable apps is your best solution to this problem.
The portable apps .paf file is technically a .zip file with a different extension.
To clarify how a portable apps installation works:
When you install the app to a flash drive with portable apps on it,
all entries that would normally go into the windows registry, are
in fact written to files within the portable apps system. Additionally, any files that might have been installed on the C drive, despite you specifying a D drive installation path, are also installed to your portable apps flash drive.
What you are looking for: an exe file you can download and just run; is rarely done these days in the world of programming. Sorry, but that is just the way most programs are developed. It is the primary reason that environments such as portableApps were developed.
The primary reason for the current install and write to the registry environment was to prevent people from bootlegging programs by simply copying the program folder from one location to the other which was very common during the dos/windows 3.1/Win96 days.
By the way, portableApps.com is not the only flash drive environment that makes programs portable. But it is likely the one that's most popular.
To test the non install portability of GoogleChromePortable, I copied the GoogleChromePortable folder from my portableApps drive to my D double clicked GoogleChromePortable.exe file to run Chrome and the it started without any problems. I could also go to various websites with it. So all you really have to do is decompress the portableapps.paf file to a folder on your C or D drive and run the program.

] | If you are analysing the performance of a long/short type of portfolio you typically do *not* calculate returns of the portfolio value itself. Typically you would calculate your daily pnl in dollar terms and for example calculate the sharpe ratio of that quantity.
The only “return” quantity that truly makes sense for such long/short portfolio is the return on your investment capital. In a long short portfolio, even though at first sight all the long positions are financed by the short ones you still need some capital to maintain your shorts, finance your longs, maintain margins accounts etc... so in other words the investment capital is the money you effectively need to practically run the long/short strategy. Therefore from a portfolio manager perspective the return that makes sense is how much pnl your strategy makes divided by this committed capital. | One approach is to simply start with your initial investment and doing a running sum of your PnL (i.e. a sum of all PnLs up until the point of interest). This will be the total portfolio value at a given point. Using those, you can simply use your formula *(new - old)/(old)* on the total portfolio values.
Note that this is equivalent to dividing the PnL of a period with the previous period's total portfolio value. This is because the PnL of a period is exactly the *(new - old)* term! |

] | A bad metaphor is like your 81-year-old Portuguese grandfather. Really, only close family members and people from that region can even understand him at all, and even then he's talking nonsense half the time, and he talks for far too long about things most people are unfamiliar with.
A good metaphor is a lot like a mime - it neatly conveys the essence of the idea in mind and requires no additional explanation.
A *really* good metaphor is much like Marcel Marceau - original, memorable, and even alliterative. | A good metaphor will parallel or easily invoke the idea you're trying to convey, without extraneous or irrelevant details. It resonates with the audience and may add to the core idea.
A poor metaphor has baggage of its own, doesn't track with the original concept, is too clunky, too esoteric, needs too much explanation, or becomes absurd. |

] | Well, first off, it should be a metaphor, not a simile. :) Ahem...
A great metaphor recasts the familiar or mundane as something strikingly different yet truly parallel. It gives a startlingly vivid picture or brings a surprising insight. A bad metaphor fails to achieve the parallel, or the fresh insight, or both. The element of surprise is an important part of a great metaphor. If we saw it coming from a paragraph away, it is far less effective; a metaphor can be bad merely because it is a cliche.
Some personal favorites:
"The wind was a torrent of darkness among the gusty trees/The moon was a ghostly galleon, tossed upon cloudy seas" (Noyes)
"The yellow fog that rubs its back upon the window-panes" (T.S. Eliot)
"Life's but a walking shadow, a poor player/That struts and frets his hour upon the stage" (Shakespeare)
"Out of the mocking bird's throat, the musical shuttle/Out of the Ninth-month midnight" (Whitman) | A good metaphor will parallel or easily invoke the idea you're trying to convey, without extraneous or irrelevant details. It resonates with the audience and may add to the core idea.

437,855 | In quantum mechanics I learned about Hermitian operators and eigenstates. It seems that Hermitian operators are always mentioned together with eigenstates. Why is that so?

] | There is no specefic reason for Hermitian operator to be mentioned with eigenstates the real importance of Hermitian operators is that their eigenvalues are real and thus they correspond to physical observables. So a study of Q.M with no mention of Hermitian operators is very limited. It is not always the case that a Hermitian operator acting on an eigenfunction always give the eigenvalue. For instance the operator representing linear momentum is Hermitian operator but when applied to atomic wave functions will not give an eigenvalue. | Generally, any linear operator will provide corresponding eigenvalues and eigenvectors (eigenstates), but they may not have the mathematical properties desirable for a physical theory. [Hermitian](http://mathworld.wolfram.com/HermitianOperator.html) operators are specifically nice to work with and well behaved. For instance, one may define an orthogonality relation via Lagrange's formula (usually already done for most operators), see the Sturm-Liouville chapter of any math physics textbook for more info on this, and Hermitian operators [provide](https://proofwiki.org/wiki/Hermitian_Operators_have_Real_Eigenvalues) eigenvalues that are real-valued, whose eigenvectors are [guaranteed](https://quantummechanics.ucsd.edu/ph130a/130_notes/node140.html) to form an orthogonal basis. John Rennie commented this [post](https://physics.stackexchange.com/questions/39602/why-do-we-use-hermitian-operators-in-qm), which points out that orthogonality of the eigenbasis is the more important feature for defining physical observables. |

] | How about using your nanomachines to make them feel so tired they can't attack your super-biologist?
1. Nanomachines accelerate the creation of molecules that signal to the brain that it needs to sleep (assuming the species goes into "full sleep" like we homo sapiens, and not "half sleep" like dolphins or whales) or feels extreme fatigue.
2. These nanomachines should also block the effects of stimulating molecules, such as adrenaline that may be released in response to the fear of becoming unexpectedly tired and sleepy.
3. The nanomachines should have a built-in deactivation mechanism (ex. based on the concentration of the molecules it creates). The molecules should also be capable of being harmlessly metabolized / disposed of by their normal biological processes (unless you want to make it permanent until you apply an antidote).
4. You can make your nanomachines be activated using some invisible, highly volatile, and odorless airborne chemical. Your super-biologist can just carry a spray can of the stuff (or even make a "fart sac" in his own body) and disable assailants. Or flood entire buildings with the stuff. | Genetic code seems like a easy answer, but it is in my opinion far reached for the hero to modify seeds so that they react to him.
The hero could instead be seen as a Prophet, bring new discoveries to the people he created, or solve their conflicts thanks to his digital library.

Or rather convince. He may learn to play on the people's affects and emotions, in a bad or a good way. He may also not show himself at all and play God, as the technology gap would be huge.

<http://www.gamers.vg/2013/04/02/resena-star-craft-ii-heart-of-the-swarm/> | There are several ways to handle this.
My favorite would be the "Dr. Who" way. Being hyper-intelligent and a billion lifetimes wise, sometimes you just need to say the right few words to the right person to make someones empire fall. If you make the threat, whisper something to someone, and then your threat comes through, this is easily the scariest way. No one will believe it till you do it, but once you do, no one will want to be on your bad side!
My second favorite is the "Vash the Stampede" way. Use a toy of a weapon they know (and fear), and just demonstrate that killing them all would be a piece of cake for you (or just run away screaming and eating donuts until everyone gives up. both work)
Then there is the "My stick is bigger" way. You don't need to kill anyone. Just vaporize a planet (like Pluto. Solve your problem AND a debate at the same time). Or just alter the conditions of their planet (raise the temperature a degree or two) to make life uncomfortable enough that they don't want to pursue you anymore. (The first pushes the 'gentile' envelope, but the later will probably just make them angrier once you undo it)
Of course, the hard part is that you don't want to make the hero TOO powerful, or else it's hard to get invested that they are in any danger (unless you want that for a more comedic story). So the first one I listed is the best way to make your character scary to upset while not making them just god-incarnate... (actually, go watch Dr. Who. I think they handle this kind of thing VERY well. Would be educational. Disclaimer though, Dr. Who will justify every phobia you know plus some if you buy into its universe.) |

] | If the queen is something like Starcraft's Queen of the Blades and sends her minions to kill you, what is the best way to show her who's the boss?
**Edit**
Inspired by [Tezra](https://worldbuilding.stackexchange.com/questions/59807/how-will-creator-discipline-the-created/59813#59813) DrWho answer I believe that some kind of non violent solution would serve the plot the best.
Maybe Tyrion dealing with [Daenerys](https://www.youtube.com/watch?v=4ETyD2tfQMM) when he's in very bad situation could give few hints.
Or the creator could teach her a thing or two about their specie past like [Javik on Thesia](https://www.youtube.com/watch?v=SgcaShRyJC8)
But if violence is really needed my answer stands.
**End Edit**
Use your [nanobiology](https://en.wikipedia.org/wiki/Nanobiotechnology) to:
1. Take over minds of her minions and turn them against her (You have a nice pets honey, you don't mind if I borrow them)
2. Insta heal your wounds when she attacks you herself, (you call that an attack, wake me up when you could do a gamma ray burst)
3. Transform her into something more into your taste (All those tentacles are vestigial, let me remove them)

] | There are several ways to handle this.
My favorite would be the "Dr. Who" way. Being hyper-intelligent and a billion lifetimes wise, sometimes you just need to say the right few words to the right person to make someones empire fall. If you make the threat, whisper something to someone, and then your threat comes through, this is easily the scariest way. No one will believe it till you do it, but once you do, no one will want to be on your bad side!
My second favorite is the "Vash the Stampede" way. Use a toy of a weapon they know (and fear), and just demonstrate that killing them all would be a piece of cake for you (or just run away screaming and eating donuts until everyone gives up. both work)
Then there is the "My stick is bigger" way. You don't need to kill anyone. Just vaporize a planet (like Pluto. Solve your problem AND a debate at the same time). Or just alter the conditions of their planet (raise the temperature a degree or two) to make life uncomfortable enough that they don't want to pursue you anymore. (The first pushes the 'gentile' envelope, but the later will probably just make them angrier once you undo it)
Of course, the hard part is that you don't want to make the hero TOO powerful, or else it's hard to get invested that they are in any danger (unless you want that for a more comedic story). So the first one I listed is the best way to make your character scary to upset while not making them just god-incarnate... (actually, go watch Dr. Who. I think they handle this kind of thing VERY well. Would be educational. Disclaimer though, Dr. Who will justify every phobia you know plus some if you buy into its universe.) | There are exactly three ways this can play out, regardless of method used.
* On the one extreme, his "gentle discipline" easily and obviously gets his point across. The creatures are cowed, and worship him as a god, because of his god-like power; the fear he causes elevates him to a deity of the creatures.
* At the other extreme, his gentle warning prompts even harsher retributions; the creatures revile him, and treat him as a demon rather than a creator-god - they would rather destroy their own race than listen to him. The fear he causes makes him an outcast.
Neither are good options. Being a deity is hard work, and being a demon just sucks. What he needs is a third option:
* His gentle discipline affects the queen who ordered the attack, and no one else; she repents, but *not* out of fear.
How? He knows how their bodies work, so he could easily create some sort of gas that would quickly incapacitate them - that is, make them fall asleep. All he needs to do is disperse the sleep-cloud around the queen's shelter, causing everyone there to fall asleep. Then, he needs to give the queen the antidote; with no followers, she will be powerless. Quietly and kindly, he should explain that she made a very big mistake, and that the sleeping guards might have instead been killed, and it would be her fault. Finally, give her the antidote, but make sure she knows the antidote is tied directly to her DNA. Unless she personally delivers it, it will have no effect. Then, leave her to personally awaken every last guard that was put to sleep - however, the antidote takes an hour or two before it starts working, she she receives no help from her guards at all.
This has the effect of allowing him time to speak (by knocking out the guards), showing his power (by selectively knocking out guards and not the queen), and humbling the queen (by making her do the dirty work of waking everyone up).
Finally, leave a message asking them to check certain chemical markers in their own DNA; hopefully, he had enough foresight to leave "[name] was here" spelled out in their genes... |

Just as humans find the noise of nails on a chalkboard inherently unpleasant, because it reminds us of our ape ancestors' warning cries, his voice could be inherently obeyed.
He could also have built into them an instinctive delight at the taste/smell of some food or spice that he has available, or perhaps even his own personal pheromones. When any of them come anywhere near him, they feel such delight and ecstasy that they forget what they were trying to do to him.

] | How about using your nanomachines to make them feel so tired they can't attack your super-biologist?
1. Nanomachines accelerate the creation of molecules that signal to the brain that it needs to sleep (assuming the species goes into "full sleep" like we homo sapiens, and not "half sleep" like dolphins or whales) or feels extreme fatigue.
2. These nanomachines should also block the effects of stimulating molecules, such as adrenaline that may be released in response to the fear of becoming unexpectedly tired and sleepy.
3. The nanomachines should have a built-in deactivation mechanism (ex. based on the concentration of the molecules it creates). The molecules should also be capable of being harmlessly metabolized / disposed of by their normal biological processes (unless you want to make it permanent until you apply an antidote).
4. You can make your nanomachines be activated using some invisible, highly volatile, and odorless airborne chemical.

This month, Aaron Hall made a post on MSO to recount the tale of his meeting with the new CEO and what was said: [An account of my meeting with the Stack Overflow management team](https://meta.stackoverflow.com/q/393552) Again, this is important for the entire network community, but it took until today for someone to cross-post this one here: <https://meta.stackexchange.com/q/344082/278659> Surprisingly (to me), the latter post was heavily downvoted and closed, then deleted by some MSE regulars.
**Why such a different reaction to these two cross-postings from MSO to MSE?** Was it because today's post is a complete copy-paste instead of just a short "go and look at this thing on MSO"? Or because it's not posted by a CM/employee? Or because it's so much later than the original post rather than on the same day?

That said I and others have in the past have brought up items of interest elsewhere on the network, and some things just work better than others.
An impactful meta post of the sort isn't and shouldn't be a mirror. We can have it much simpler than that
We need to introduce the topic in summary, bring in the key things that would interest the MSE public and have a call to action for answers.
It also needs to be timely (there's new developments since and it's hardly a hot topic). That the post was a little older may not have helped.
We can trust people to read a post elsewhere. We just need them to know why and open the floor for feedback amd responses.
In addition to the example Rand gave consider my [post here](https://meta.stackexchange.com/questions/332499/how-could-we-improve-our-planned-post-notice-improvements).
It's 3 paragraphs. I introduce the post. I go into why it is of interest to meta. I give a precis of content of interest and well, it worked better than a full mirror.

28,822 | I have been growing my own Chilli's in the kitchen window sill, but this has resulted in a massive greenfly epidemic.
I've tried two different brands of bug spray Provado Ultimate Bug Killer and Doff All in one bug spray and they seem to be immune! Both are supposedly for use on fruit and veg but they don't seem to do a thing :(
Does anyone have any recommendations for getting rid of them and also preventing them from coming back?

] | You've said you used Provado Ultimate Bugkiller and Doff All in one, three weeks in a row. Provado Ultimate Bugkiller should only be repeated every 10 days, and is both systemic and contact in action. Because its a systemic, that's why it shouldn't be used more often.
Doff All in One bugkiller is a contact killer only - I've been unable to access the instructions for use, but given it only contains fatty acids, the likelihood is you need to repeat treat every few days, ongoing. If it says you can use it every three days, then do so - when you spray, spray thoroughly, till run off, including beneath the leaves and including the stems.
I'm afraid there is no permanent solution to aphid infestation - systemic sprays, if sprayed as described above, keep plants clear for longer, roughly a week to two weeks, depending on the product, whereas contact ones only kill what's on the plant when you spray. | Most of us who have grown chillies have encountered this situation with greenfly/aphids already.
As Joy Michaud says in his guide *"There is simply no way of avoiding the pest, and anyone who has not had a problem with aphids just haven’t YET had a problem."* <http://www.chilefoundry.com/2012/03/16/joy-michauds-guide-to-control-of-aphids-in-pepper-plants/>
It is up to you, but you may want to consider using natural pesticides to reduce your greenfly or aphid problem if you intend on eating your chillies once they've grown.
Luckily, there are some great alternatives to synthetic chemicals, as mentioned here: <http://www.gotscience.org/2015/07/ladybirds-and-other-natural-pesticides/> and these may work better than the products you have already tried:
1. Companion planting (some garden plants may inhibit or repel pests.)
2. Soft chemical measures (specially developed soap sprays, stinging nettle/rhubarb solution or essential oils)
3. Ladybirds (Ladybugs) and other natural predators of greenfly (Since soap solutions aren’t recommended for all plants and trees, ladybirds may be an option for countering aphid infestation.)
If you can take your plant outside that would also increase it's chances of meeting natural predators. Also see www.defenders.co.uk/ for more options. |

* If the developer certificate is not installed, you can either download the correct one from developer center or you need to create new developer certificate.
* If you are creating a developer certificate, you need to request for a certificate from the authority, then upload the .certSigningRequest file to the developer center and generate your developer certificate. Then update your current provisioning profile also.
2. Run configuration for your project is not correct one.
* In some cases, Titanium Studio does not reset your project configuration automatically. So you need to reset it manually. For that
* Open your Titanium Studio, then open your project.
* Right click on the project then select Run as -> Run configurations.. (see the image 1)

Using Illustrator's Image trace on that larger version yields **much better** results.

] | In today's business world, culture is a real thing that get either created ad-hoc or deliberately through top management efforts. There are books on how to create culture in businesses.
Basically, a business leader decides that certain elements of culture are important and structures both events and compensation to encourage those. So, events such as "all hands meetings", off site team building actions, and competitions are used. At the same time, leaders use 360 reviews, employee surveys, and compensation programs (your raise is dependent on having x score on y element of your employee survey).
To use those on a population basis: Corporations band together to sponsor community events that promote the specific culture you want. For example, religious festivals can be sponsored. (Mark Cuban has sponsored the Dallas St. Patrick's Day parade. Corporations pay a lot for sports stadium naming rights. Notice how many corporations paid a lot for Super Bowl ads which are in a "religious" event.) (The flip side is also worth looking at: where did the money come from to support mob actions, cross burnings, etc.) Corporations can pay for population surveys to see how well their efforts are working to generate the culture they want.
The biggest problem is when corporations start working at opposite purposes. You will find major campaigns to push culture in competing directions. Dallas had a business council that coordinated business cultural efforts for a number of years till people rebelled against it. | >

Objects of cultural significance can potentially be manufactured anywhere. Examples range from idols crafted for clandestine worship to craftspeople doing their jobs and artists questioning the status quo.
But you do need history for culture to develop. Since manufacturing a fake (sense of) history from scratch won't do (after several generations you might be able to manipulate the memory of history, but that's another story), I think you (or the commercial organizations) should embrace the diversity of the cultures that currently inhabit your new world.

37,209 | We few of us are planning to build a foley pit, but are quite concerned as to how to do water foleys. Till now we have been using plastic buckets and metal tubs filled with water.

] | One tip - be sure it's round. Square tanks have terrible slapback resonance. | Purpose built Foley stages usually have water pits built into the floor.
The bigger the pit the better as one of the biggest issues is that the water tends to hit the sides of the tub or pit and splash back, which is a bit like adding echo to the sounds you're recording. Having a pit that has an angle to all the sides will help reduce these unwanted extra sounds. I suggest that you make your water pit out of concrete so that the plastic sound of a bucket or the metal sound of a tub do not interfere with the purely aquatic sound you need.
I've never tried it, but I've heard of someone who used a round kiddie wading pool and lined the walls with foam rubber. It worked for them.
Yes, water is messy. |

Individually, probably not. But as a collection, 'catalogue copyright' just might apply.
In some places, catalogue copyright is used for works that normally could not be protected by copyright, but which still merit some form of protection. Lists, catalogues and directories are typical examples: the protection time is usually less than 10 years.
If it does apply or not depends on the situation: is it national law (say, US Copyright law) that applies? is it the Berne Convention? The World Copyright Convention? Or even individual trade agreements between two countries?
It would almost certainly not be applied for fairly small, random downloads: it might however be applied for full download/dump of a chess database. An organization that plans to use it may add identifiable material that makes it possible to say where the information was taken from. |

This [Fader article](http://www.thefader.com/2012/05/03/footnotes-philip-glass-scores) seems certain that the music is from Philip Glass's score of Kundun, the 1997 Martin Scorsese film about the Dalai Lama.

Are they referring to an actual movie? What is it? [You can see the scene [here](http://parksandrecreation.wikia.com/wiki/File:Parks_And_Recreation_Operation_Ann_-_Clip_1).] | 2015/11/26 | [

======
This [Fader article](http://www.thefader.com/2012/05/03/footnotes-philip-glass-scores) seems certain that the music is from Philip Glass's score of Kundun, the 1997 Martin Scorsese film about the Dalai Lama. A monk died in it, though I don't think he killed himself. The young Dalai Lama has visions of many dead monks as well,
Listening to the [Clip from Parks and Rec](http://parksandrecreation.wikia.com/wiki/File:Parks_And_Recreation_Operation_Ann_-_Clip_1) I originally thought it was the track [Lhasa at Night](https://www.youtube.com/watch?v=gd39A4pF-HI), due to the horns, but there is no gong in this track even though the rest of it sounds pretty similar to me. Currently listening to the album to see if I can find a better match. | Its referring to a movie about a monk named [*Thích Quảng Đức*](https://en.wikipedia.org/wiki/Th%C3%ADch_Qu%E1%BA%A3ng_%C4%90%E1%BB%A9c), i suggest you guys read about it, really good read :) |

[](https://i.stack.imgur.com/WZkxP.jpg) | I was assigned to the 50th Medical Co.(Clr) in Long Binh 1965 - 66. This unit was a second tier medical facility treating VietCong prisoners until they would be well enough to be sent to an RVN POW camp. The unit also handled U.S. Army prisoners awaiting transfer to CONUS after being convicted of a crime and awaiting transfer prison. The facility was enclosed with fencing and barbed wire and had (for the VietCong) three wards. It was guarded by MP's. The doctors and medics caring for them treated them just like any other patient. Jokes were made about the "slopes", etc. but since they didn't speak English I think they were not likely too offended. They got the same food as the troops caring for them, except they got rice with every meal as I remember. There was never any abuse, torture, etc. Some became friends with various medics. They all hated to be released from this facility and be sent to the RVN POW Camps and often re-injured themselves to prevent that. |

19,930,258 | We have an ASP classic website running on an IIS 7.5 dedicated server with no other sites running on it.
The wait time for the homepage on the initial request is about 5.2 seconds but then subsequent wait times are a much more acceptable 133ms.

] | After a thorough investigation I discovered that the slow initial Time to First Byte was caused by the database connection string. A period "." was being used for the default server instance name rather than the name of the server being specified. When I changed the period to the server name the TTFB dropped to normal levels.
Thanks very much to all who answered. | IIS7.5 has a [plugin which initializes applications](http://www.iis.net/downloads/microsoft/application-initialization) and helps reduce the slower performance of that initial load after an IIS restart or app pool recycle.
You can also install this via the Web Platform Installer.
Once installed you should notice there is a new option in the Advanced Settings of each IIS application pool allowed you to control this action on an application pool basis.

3,522,555 | When MVC first came out, I was reading about it everyday and learning all I could about it. About the time MVC 2 RC2 came out, I stopped learning for various reasons (new house, new job, laziness).
I now want to get back into MVC ... I have a half written blog that I want to finish, but I feel rusty when it comes to anything MVC. Can anyone provide me some good links to refresher courses on MVC? I don't need to learn from scratch, but I want to refresh, then learn about changes from MVC 2 RC2 to MVC 3.
EDIT: Anyone know an ETA on when MVC 3 is going to release? Should I convert my current MVC 2 project to MVC 3 ... or wait for an RC ? | 2010/08/19 | [
