] | I think I read the same book you did, and the phrase you’re looking for struck me as it struck you, and has stuck with me:
*[The Case for Mars](https://books.google.com/books?id=NC8XZEddojsC&dq=%E2%80%9CThe%20case%20for%20mars%E2%80%9D%20gaslight&source=gbs_navlinks_s): The Plan to Settle the Red Planet and Why We Must*, by Robert Zubrin, published by Simon and Schuster, 2012.
In it Zubrin describes the steps needed for human habitation on Mars, starting with the first and most critical step: manufacturing propellant for liftoff and return for the first visitors (because carrying enough fuel for the return trip from Earth is prohibitively expensive to lift out of Earth’s gravity well).
Here, he says:
[](https://i.stack.imgur.com/V9cJy.jpg)
>
> In 1976, Professor Robert Ash, now of Old Dominion University, and some JPL collaborators published a paper laying out some *simple, robust and well established* (**Gaslight era**, to be precise) chemical engineering processes...
>
>
>
So I think what you’re looking for is:
### *Gaslight era*
But I want to offer a caveat here: this is *not* a standard or generic term for *any* proven technology.
Instead, he’s saying for this specific purpose — manufacturing propellant *in situ* — the techniques developed and perfected during the 19th century by the first wave of “modern” scientists who discovered chemistry, would be sufficient for the purpose.
The goal of the book is to make a clear case that Mars can be settled in a practical and realistic way. Part of that is recognizing that some of the most critical processes don’t require “future tech”, or even high tech, and can be done on a [reasonable] budget.
In other words, the argument behind the phase in this context is:
*The same fuel that those pioneers created processes to efficiently and effectively manufacture from simple ingredients, sufficient to move the world from candlelight to gaslight, to illuminate this world, in a sense, is also fuel sufficient to get our astronauts home from another world altogether.* | Tried and true is another way to plainly state some ting is reliable.
Gaslight is an old psychological suspense mystery film. Most of the use of the word in current media is figurative. |

15,252,284 | I am learning Spring framework and currently reading a book about it.
In this book it says that a Spring singleton is different from a Java singleton?

] | The Java singleton is scoped by the Java class loader, the Spring singleton is scoped by the container context.
Which basically means that, in Java, you can be sure a singleton is a truly a singleton only within the context of the class loader which loaded it. Other class loaders should be capable of creating another instance of it (provided the class loaders are not in the same class loader hierarchy), despite of all your efforts in code to try to prevent it.
In Spring, if you could load your singleton class in two different contexts and then again we can break the singleton concept.
So, in summary, Java considers something a singleton if it cannot create more than one instance of that class within a given class loader, whereas Spring would consider something a singleton if it cannot create more than one instance of a class within a given container/context. | A Java singleton, per the design pattern where instantiation is restricted to one, usually per JVM class loader by the code. [Wikipedia](http://en.wikipedia.org/wiki/Singleton_pattern)
A Spring singleton bean can be any normal class you write, but declaring it's scope as singleton means that Spring will only create one instance and provide its reference to all beans that reference the declared bean. You may have many instances of that class in your application, but only one will be created for *that bean*. You may even have multiple beans of the same class all declared as singleton. Each bean will create exactly one instance of the class. [Spring 3.1 Doc](http://static.springsource.org/spring/docs/3.0.x/reference/beans.html#beans-factory-scopes) |
169,156 | EDIT:
Because of the repeated requested by people to stay concise I am editing the question.
I joined a company, a colleague of mine has been really unprofessional to me.Lot of times shouting at me. Blocking me from working and really making it difficult to work.
In the meanwhile, a new manager comes in. I was taken aback when he pretty much was rationalising this bad behaviour.
I raise the issue with the ceo. He also seems to be aligned with the ceo.
Later I realise that this colleague of mine is related to the ceo.
The ceo organises a patchup call, i resign from job, since it would not make sense to do the right thing?

] | I am going to pose a frame challenge here.
Your question oozes with highly biased judgement that favors yourself over anyone else, and there are several cases of needless emphatics.
Self-aggrandizement
-------------------
>
> They hired me as senior engineer, and my performance was excellent to say the least. I have saved the company lot of money, by bringing to life things they had given up on.
>
>
>
It's one thing to say your work was well reviewed by the company. It's another to label yourself "excellent to say the least". "saved the company lot of money, by bringing to life things they had given up on" sounds near-messianic.
This is textbook [ad hominem](https://en.wikipedia.org/wiki/Ad_hominem)
-----------------------------------------------------------------------
Then you go on to describe the people you work with:
* The engineer in focus is beyond "unprofessional". I say "beyond" because you specifically point out that "calling him unprofessional would be an understatement"
* The CTO is "weak"
* The senior manager is "from the 80's"
* The manager is doing "weird" politics, like approaching people, talking to them, and being on the same side (???)
Gosh, it seems like everyone except you is incompetent.
I especially got a chuckle from your description of the senior manager:
>
> And after all this tries to pretend as if he is doing a great job, and everyone should be grateful to him.
>
>
>
...because that is *exactly* how I interpret your description of yourself, and how you seem to expect people to respond to your input about developer X.
Clear bias leads to a lack of trust
-----------------------------------
**I am not interested in arguing details with you** about who said what. But I am very strongly inferring here that you are presenting a biased story where you've not particularly tried to remain objective or pragmatic, which in turn leads me to wonder how this narrative has been spun, and where the more objective origin lies.
It seems to me that you are adamant about your opinion on how a company should operate being the only correct one. This is clear from your descriptions of others. You state (alleged) fact, and every time implicitly rely on the "and this is not how you should do it" inference, as if there's one universally agreed upon way of doing things.
This approach of yours especially goes off the rails when describing the manager. Other than you subjectively labeling it as "weird", there is *nothing* in your list of his actions that even remotely argues that this manager is not performing their job.
Your interpretation of their alleged "mantra" is *even by your own claims* based on rumors and inference.
There is nothing substantive about any of the people you've described, even though you've gone to great lengths to paint them in a negative spotlight. This significantly backfires for you. Rather than prove just how much better you are, it shows you as a petty, vindictive and fiercely competitive employee, none of which are admirable traits.
Vagueness to avoid substance
----------------------------
>
> He starts shouting at meeting, prevents me from sometimes doing my job and asking for unreasonable changes in the code.
>
>
>
It's an odd coincidence that I've had almost the exact same complaints levied against me from specific coworkers (in different workplaces I was detached to). Which allows me to put the spotlight on how vague and subjective these claims are. Using my personal example:
* The unreasonable changes? Using commonly agreed upon good practice development strategies that this developer refused to learn (concretely: writing tests and documentation, promoting loose coupling and encapsulation)
* Preventing them from doing their work? Well, these "useless" good practices eat up all the time they could spend on writing (bad practice) code and the dozens of bugs they need to fix (due to bad practice development)
* Shouting at meetings? Well, I refused to keep letting them devolve any meeting into arguing whether we should employ good practice for *every* meeting, no matter the topic of the meeting. I did not shout or lose my cool, but I did assertively shut down these constant distractions and cyclic discussions.
I'm not claiming my experience precisely matches your experience, but given the emphatic nature of your descriptions and your unwillingness to do things any way other than how you think they need to be done (as inferred by me), this example shows just how much vagueness there is in your concrete problems with this alleged "bad apple" on your team.
I am strongly convinced that your persistent vagueness about concrete problems (both about this developer and in your description of why all your managers are incompetent) is a **conscious effort to twist the argument in your favor**. The way you structure your arguments, leave conclusions up to implicit inference, and emphatically describe anything you disagree with as unfavorable makes it really hard to convince me otherwise.
The workplace is about communication, not just work
---------------------------------------------------
The goal of this answer is not to argue with you, but rather to help you overcome the obstacle in the workplace that you're faced with. I *genuinely* want to help you and make your work experience better. However, it seems like the obstacle is not what you think it is.
I'm not claiming that you're wrong about whatever the original disagreement (which you did not explain) was. I can't arbitrate on things you don't mention, but I want to make it clear that I'm not saying that I think you're wrong about literally everything.
What I am certain of, is that your attitude is at best selfishly biased and unfair towards your coworkers, and at worst it is downright toxic. Over all, **this makes you the bad apple**.
Think of it this way: how likely is it that *you alone* are more correct in assessing this developer and how they function within the company, when *three* people (CTO, senior manager, manager) all evaluate this developer completely differently?
I'm not saying it's impossible you're right, but I would expect *some* level of humility and a proper argumentation as to why you think the other three people are wrong. In this answer, you have only resorted to attacking their character with unsubstantiated judgmental descriptors. There is not a shred of substantive argument as to why these people's evaluation might be misguided.
Your biased-bordering-on-toxic attitude is likely at the root of why your input is being on this developer is being ignored.
Based on personal experience in many workplaces, often those with endemic issues (as a consultant, I am often detached to workplace that have gone awry to fix things), I suspect that what has happened here is that there has been a genuine but harmless disagreement, and that you've doubled down on your position several times since then, leading to this escalated scenario where you no longer present it as just a disagreement, but almost to being a conspiracy of an entire company filled with incompetent people who are all working together to exclude you.
The conclusion
--------------
If you genuinely feel that everyone is as incompetent as you say they are, they you're either going to have to learn to live with the incompetence, or find a new place to work. You're not going to be able to single-handedly run the place, no matter how right you may have been about the original issue.
However, if the problem is rooted in your attitude, at least the part that turned a harmless disagreement into an alleged "conspiracy of the incompetent", then this problem is going to repeat itself wherever you work. It's time to learn to trust in others, and have some humility about your own opinions.
I have *plenty* of opinions that are different from how my company operates, but I choose to not die on these hills. I do my job and provide input to the degree my input is desired. My personal opinions on how certain things should be done, I limit to either professional projects where I do get free reign or personal projects where I can do it my way.
And as much as you may think your opinions are better, most developers who I've talked to who did things their own way in personal projects sometimes do realize that their approach had a significant flaw that they had not yet spotted.
Humility is not weakness, it is strength. | You post is very unnecessarily long. It could be summarized as this:
"I worked for a very dysfunctional company that was unwilling to change so I left".
It happens all the time and might happen to you again in the future. No need to get upset about it, just move on and hopefully improve your compensation package in the process. Software developers should be thankful that there is a lot of mobility in their careers, and changing jobs (even in a short time) is not seen as a blight. Sometimes a job is so dysfunctional that it is accepting a lower compensation package is acceptable just to move on.
The best "revenge" is resigning with a smile on your face and saying nothing during the exit interview. Then going on and doing great things at another company. |

Two things. Treebeard hasn't seen Saruman in a long time--which when Treebeard says a long time, HE MEANS IT! And, Saruman was already corrupt from Treebeard's description. So, it's plausible that he would want Sauron on the chessboard, so to speak, to create a situation where he could be the one who might "become a Power."
EDIT: I suppose what I mean is that Saruman vying for power could be spotted and stopped. The Necromancer, however, would be a diversion! And, it worked---Gandalf was caught off guard when he traveled to Saruman only to be imprisoned atop Orthanc. |

Two things. Treebeard hasn't seen Saruman in a long time--which when Treebeard says a long time, HE MEANS IT! And, Saruman was already corrupt from Treebeard's description. So, it's plausible that he would want Sauron on the chessboard, so to speak, to create a situation where he could be the one who might "become a Power."
EDIT: I suppose what I mean is that Saruman vying for power could be spotted and stopped. The Necromancer, however, would be a diversion! And, it worked---Gandalf was caught off guard when he traveled to Saruman only to be imprisoned atop Orthanc. | At the time of *The Hobbit* Saruman had sent servants to search the *Gladden Fields* west of *Mirkwood*, so yes, he was already 'evil'.

What happens is that the ShowDialog does not return so the top-level message pump is waiting for your app to return from processing whatever event made it call ShowDialog; this is no different than if your handler for this even were grinding CPU. So, yes, in that sense, the message pump is blocked.

I have a 6 monitor stand. I envision the 2 monitors on the right hand side to be the HP, and then the 2 in the middle as well as the 2 on the left to be the Acers. The 2 in the middle would be the ones on a switch so I could toggle them back and forth from the work Lap Top to my home desk top.
My work lap top is used exclusively for using a cloud software program, internet research, and the microsoft office suite
My desktop computer will likewise mostly be used for school work purposes, so mostly running microsoft, as well as online classes, internet research and that sort of thing. However, I do intend on taking some coding classes and would like to be set up for using Python and some other Data Analysis programs, and may possibly want to use it for Audio recording/editing and video editing.
Can this be done?
What equipment/hubs would I need? Can this just be done with hubs, or am I going to have to get a graphics card for the desktop? I won't be able to modify the work laptop in anyway physically, so can I run 4 monitors with a hub from the HDMI and a Hub from the USB SS?

The order doesn't matter. Windows will happily accept any changes to your RAM configuration.
**That drive must not be trusted** however. Sometimes disks with bad sectors work for years, but sometimes the situation gets worse and leads to data loss. The drive may be able to remap those sectors to spares as they are accessed, but it's also possible that it has already run out of spares. In that case you'll be losing data.
Anyway, make sure your automated backups are working and restorable. If you don't have automated backups, you should. Disks die sometimes and yours was kind enough to give you a warning. Veeam Agent is my preferred backup solution, but there are others.
You'll be installing Windows from scratch anyway (you can't upgrade to 64-bit in place), so consider upgrading to Windows 10. Windows 7's support has ended and it's not safe to use anymore. The Windows 10 installer will accept Windows 7's product key, so there's no extra cost to this upgrade.

Please read <http://www.jasypt.org/howtoencryptuserpasswords.html> in order to know more about the way passwords are processed in jasypt. | Never used Jasypt, but from their [documentation](http://www.jasypt.org/encrypting-passwords.html):
>
> A salt of the specified size is generated (see org.jasypt.salt.SaltGenerator). If salt size is zero, no salt will be used. It is advisable that you use a random salt generator like org.jasypt.salt.RandomSaltGenerator (which is the default) for higher security.

If you're writing a paper (or book or report or document) about your project, then you tend to stay on task.
Start with an outline of what you're doing: use case overview, release 1, release 2, release n. Write down an summary of the use cases. Prioritize them. Get them into sprints and releases.
Each release has a use case view, logical view, processing view, component view, deployment view. For the sprint, detail the use cases. Publish the HTML document to show what you're going to do. After detailing the use cases for the sprint, write the logical model. Write code to support this. Write the processing documentation. Write code to support it. Create modules. Write the component view documentation. Write the tests and supporting documentation. Publish the sprint results as an HTML document.
Repeat for each sprint. Review and edit your document from time to time.
There are lots and lots of literate programming tools. They can help you produce a source that creates the documentation *and* the code both from a single text.

If you're writing a paper (or book or report or document) about your project, then you tend to stay on task.
Start with an outline of what you're doing: use case overview, release 1, release 2, release n. Write down an summary of the use cases. Prioritize them. Get them into sprints and releases.
Each release has a use case view, logical view, processing view, component view, deployment view. For the sprint, detail the use cases. Publish the HTML document to show what you're going to do. After detailing the use cases for the sprint, write the logical model. Write code to support this. Write the processing documentation. Write code to support it. Create modules. Write the component view documentation. Write the tests and supporting documentation. Publish the sprint results as an HTML document.
Repeat for each sprint. Review and edit your document from time to time.
There are lots and lots of literate programming tools. They can help you produce a source that creates the documentation *and* the code both from a single text.
I use [sphinx](http://sphinx.pocoo.org/) and [PyLit](http://pylit.berlios.de/) but that's because I'm a Python programmer. | It depends on how you can distinguish and handle different tasks, because you'll need to take a look at every single step of the development process.
I think tools are only useful if you already know how to use them and one of the worst mistakes is learning how a tool works rather than learning what to do with it.
First, in my opinion, you have to write down what you expect the software will do and specially what it won't do. That's a crucial point. The next step is divide the final system into lower subsystems, making the building process easier. And last but not least you'll need to choose your tools. Basically a good IDE, a VCS and a data modeler. You can add a lot of other tools to help, but take care not to start on the wrong track.
Well, the beginning seems not so attractive, but the process will become fun along the time. |

] | Answering an old question but there are issues with the winch launch that have not been covered; one is a wing drop on the ground run. If the wing touches the ground while being winched then the glider can cartwheel if the pilot is not quick enough or able to pull the cable release. The winch can keep pulling the aircraft until the winch operator spots a problem and stops the launch or the pilot pulls the release.
This happened at my club about 3 years ago (2012) with an experienced pilot in a Nimbus 3. He died of his injuries.
There is also the possible issue with cable fouling, although unlikely it is possible in a shallow fast climb to dip the nose on release and impact the cable if the cable parachute has opened. That will ruin your day.
Pulling too far back on the stick on the ground run can cause an overly-quick rotation into a steep climb causing the tail to hit the ground. While removal of the tail will reduce drag considerably it will cause one of two control issues.
In winch launches you are very much at the mercy of your ground crew and winch driver. All it takes is for a misheard instruction or someone to mistake the glider model and you could be launched on the wrong winch setting. An underpowered or overpowered launch can cause a lot of problems for a pilot but then that is why we drill for problems. I have to admit to signalling a launch for the wrong type of glider, thankfully it was spotted by the pilot who radioed a correction but I have seen gliders launched on the incorrect winch setting on a few occasions.
Pilots of Petrol Pigeons don't have a cable to worry about. | Most gliders do have battery and/or solar-powered avionics and comms, so there can be electrical failures. In fact, one must take battery life into account for long flights.
Gliders often fly much higher than other general aviation aircraft, so failure of the oxygen system with attendant hypoxia is a risk. |

] | The number one emergency in a glider is a tow rope break at low altitude, less than 200 feet above the ground with no appreciable headwind. Below 200 feet, the proper technique is to land straight ahead, which usually means landing off airport.
Between 200ft and 500ft, it is possible to make a U-turn back to the runway, and land in the opposite direction in which you took off. The main hazard with this kind of landing is landing with a tailwind, and once the wheel touches the ground, the flight controls operate in the reverse direction.
Above 500 feet, it is possible to fly an abbreviated pattern and land on the runway you took off from.
Add 50 feet of altitude for each 10 knots of headwind.
Some other tow emergencies are inability to release to tow rope, in which case the tow pilot needs to release the rope on his end; engine failure of the tow-plane; and a double tow rope release failure, which means the glider needs physically break the tow rope (it has a pre-determined breaking strength of 80-200% of the weight of the glider) or to land behind the tow-plane.
You can also run out of altitude and have to land in a field, which is called an "off airport landing." Someone has to come and get you with a trailer, and you disassemble the glider and drive it away. One hazard is the off airport landing in a field, and the farmer comes out with his shotgun.
Other hazards are flying into the clouds or into severe turbulence, which can happen when the glider pilot is flying "wave," a kind of lift generated by strong winds in proximity to
mountains.
When thermaling, you are flying very tight steep turns, often with other sailplanes who are also trying to gain altitude. Everyone is supposed to fly the thermal in the same direction, and there is the hazard of colliding with other gliders.
Reference: [FAA Glider Flying Handbook - Abnormal and Emergency Procedures](https://www.faa.gov/regulations_policies/handbooks_manuals/aircraft/glider_handbook/media/gfh_ch08.pdf) | Let me add some more possible failures:
* Incorrectly assembled aeroplane ( actual reason for some tragic deaths ). Avoided by following check lists and instructions before even contemplating to start.
* Items dropped in the cockpit may lock up controls ( I did drop a water bottle down among the cables, luckily not locking up the controls )
* In air collision, especially when flying in clouds ( One reason flying in clouds generally not allowed in competitions )
* Heat stroke: the cockpit has plexi glass all around and in sunny weather it will be very warm. Never forget you most important personal safety item, the hat.
* Out of oxygen: we from the "low lands" can not stand any long time up high. Once above 10.000 feet (3.000 meters) we should have Oxygen along. Note that in wave flying a glider might reach 10.000 meters.
* Out of energy, already mentioned in other answers. Pilots train for this and are supposed to commit to landing once reaching minimum height above ground. Add a bit to the minimum when over rocky terrain or over dense woods. |

] | The number one emergency in a glider is a tow rope break at low altitude, less than 200 feet above the ground with no appreciable headwind. Below 200 feet, the proper technique is to land straight ahead, which usually means landing off airport.
Between 200ft and 500ft, it is possible to make a U-turn back to the runway, and land in the opposite direction in which you took off. The main hazard with this kind of landing is landing with a tailwind, and once the wheel touches the ground, the flight controls operate in the reverse direction.
Above 500 feet, it is possible to fly an abbreviated pattern and land on the runway you took off from.
Add 50 feet of altitude for each 10 knots of headwind.
Some other tow emergencies are inability to release to tow rope, in which case the tow pilot needs to release the rope on his end; engine failure of the tow-plane; and a double tow rope release failure, which means the glider needs physically break the tow rope (it has a pre-determined breaking strength of 80-200% of the weight of the glider) or to land behind the tow-plane.
You can also run out of altitude and have to land in a field, which is called an "off airport landing." Someone has to come and get you with a trailer, and you disassemble the glider and drive it away. One hazard is the off airport landing in a field, and the farmer comes out with his shotgun.
Other hazards are flying into the clouds or into severe turbulence, which can happen when the glider pilot is flying "wave," a kind of lift generated by strong winds in proximity to
mountains.
When thermaling, you are flying very tight steep turns, often with other sailplanes who are also trying to gain altitude. Everyone is supposed to fly the thermal in the same direction, and there is the hazard of colliding with other gliders.
Reference: [FAA Glider Flying Handbook - Abnormal and Emergency Procedures](https://www.faa.gov/regulations_policies/handbooks_manuals/aircraft/glider_handbook/media/gfh_ch08.pdf) | Most gliders do have battery and/or solar-powered avionics and comms, so there can be electrical failures. In fact, one must take battery life into account for long flights.
Gliders often fly much higher than other general aviation aircraft, so failure of the oxygen system with attendant hypoxia is a risk. |

15,061 | I work with about 60 schools and many classrooms and would like to replace Powerpoint entirely (for many reasons). Moving to the browser and writing HTML and assets in a CMS that publishes to templates is standard, but we lose one key thing in the classroom environment: animations.
What I'm imagining is having our classes in the browser and writing them in an authoring tool that would allow the class writers to select CSS/JS animations (for text, images or scrolling (ex: next page/section animations)) as well as assets (sound, video, images) to work with.
I am not sure if anything like this exists, but if anyone has any ideas I'd greatly appreciate the feedback!
Edit: I should have included that by "replace Powerpoint entirely" I do not mean with a free or alternative version of Powerpoint (ex: WPS, LibreOffice).
Edit 2: By "class" I am talking about classes with students. I'm looking to replicate a Powerpoint experience in-browser and would like a CMS/authoring tool that allows me to build such an experience. As I mentioned above, most CMS's can do all this, but they are lacking animations. I'd like a CMS that can save a pre-set bank of CSS/JS animations that I can use to more easily create my content. | 2015/01/05 | [

18,530 | After 30 minutes of mashing, I checked the temperature at it was 142F/61C. I added 3/4 gallon of boiling water and brought the temp up to 155F/68C. It maintained between 152-155 for 60 more minutes.
Mashing at different temperatures causes different enzymes to be more activated than others, and that these enzymes break down the starch differently.

Basically you had a short beta mash and stepped to an alpha. The result is a more fermentable beer.

] | Permanent magnets can't be explained in terms of Maxwell's Equations or Classical Physics in general. As most (if not all) of the phenomena that arrises due to microscopic behaviour, you need Quantum Physics to explain it properly.
Permanent magnetism comes from spin. Spin is an intrinsic property of every particle, like mass. It is quantized, coming in integer multiples of one half. It is one type of angular momentum. The important thing you need to know about spin, in order to answer your question, is that it couples with the Magnetic Field and also 'produces' its own little magnetic field. More precisely, the spin of a particle implies in a magnetic dipole moment.
Just as every fundamental particle (like electrons and protons) has its spin, so do composite particles (like an atom). It happens, though, that the magnetic moment of a single atom is very weak, so you need all the atoms in a lattice to align, so that their fields sum up, in order to get something apreciable and detectable. And that's what happens when you put a non-magnetized piece of iron on a magnetic field. Its atoms align and you get a magnet, simmilarly to when you have lots of tiny magnets togheter.
But, now, why aren't all materials magnetic, you ask?
Because for most atoms the spins of different electrons, togheter with the spin of the nucleus, cancel out. You need a very specific arrangment of atomic structure in order to form crystals that can have its atoms with sobressalent spin and aligned, thus creating a magnet. | >

.
There you go!
You can model the permanent magnet as made up of lots of little current loops that each form the dipole element of an atom. (*Why* that’s a good model is a separate question). Together they act like a bigger loop.
The field from that also induces a corresponding magnet in the iron of the refrigerator door. Again, that looks like a current loop.
And those two effective loops are parallel, so they attract. |

] | The cost index is a number used in the Flight Management System (FMS) to optimize the aircraft's speed. It gives the ratio between the unit cost of time and the unit cost of fuel.
With this number, and knowledge about the aircraft's performance, it is possible to calculate the optimal speed for the aircraft, which results in the lowest total cost.
Speeds slower than the optimal speed will result in less fuel burn, but also in more flying time. The cost of the extra flying time outweighs the fuel savings at speeds below the optimum speed.
Speeds faster than the optimal speed will result in more fuel burn, but also in less flying time. The saving of less flight time do not outweigh the fuel burn at speeds above the optimum speed.
A low cost index means that the cost of time is low or that fuel is expensive. It will result in a low speed. High cost index means high cost of time (e.g. passengers about to miss their flight connection) or low fuel price (rare these days).
At the minimum cost index (0) only fuel counts. This will result in the aircraft flying at Maximum Range Cruise. At the maximum cost index only time counts. This will result in the aircraft flying at Maximum Cruise Speed (Vmo / Mmo with a buffer)
Airlines generally have a standard cost index they use for planning and adjust them on a flight by flight basis.

] | The cost index is a number used in the Flight Management System (FMS) to optimize the aircraft's speed. It gives the ratio between the unit cost of time and the unit cost of fuel.
With this number, and knowledge about the aircraft's performance, it is possible to calculate the optimal speed for the aircraft, which results in the lowest total cost.
Speeds slower than the optimal speed will result in less fuel burn, but also in more flying time. The cost of the extra flying time outweighs the fuel savings at speeds below the optimum speed.
Speeds faster than the optimal speed will result in more fuel burn, but also in less flying time. The saving of less flight time do not outweigh the fuel burn at speeds above the optimum speed.
A low cost index means that the cost of time is low or that fuel is expensive. It will result in a low speed. High cost index means high cost of time (e.g. passengers about to miss their flight connection) or low fuel price (rare these days).
At the minimum cost index (0) only fuel counts. This will result in the aircraft flying at Maximum Range Cruise. At the maximum cost index only time counts. This will result in the aircraft flying at Maximum Cruise Speed (Vmo / Mmo with a buffer)
Airlines generally have a standard cost index they use for planning and adjust them on a flight by flight basis.

I would recommend choosing **Something Else**. That's the only way you can ensure the OS isn't going to be installed on your SSD.

109,177 | Consider the following diagram. Once every 2 seconds a car enters from the top and travels down towards the exit. Once every 3 seconds a car enters from the left and travels to the right exit. In the beginning there are no cars. On the 2nd second a car will enter at the top. On the 3rd second another car will enter from the left. On the 6th second, cars will enter at both locations and so on. Once a car is on the road it will attempt to move towards its exit location, moving one square per second. If the traffic light is red for the given road then the car will not move and only move when the light is green. If the road is full of cars and a new car cannot enter the road, then an accident happens and everything comes to a stop. Cars that exit are taken off the road. There cannot be more than one car per square.

This allows the vertical-road cars to run uninterruptibly (showing green when a car is in a square directly in front of the intersection), and the horizontal-road cars will wait at most 1 second per car. Since there are 2 free squares between the horizontal-road cars (if we extend the road to the left), there will always be enough space to not create a jam.

] | I recommend Astaro without reservation. It isn't free, but it is inexpensive. It uses the open source package OpenVPN for both IPSec and SSL VPN connectivity. The Astaro management interface is quite clear, and deploying the VPN is straight-forward. Plus, you get a very good firewall along with the VPN.
Q1 (Cheapest): Rolling your own is inexpensive if your time is considered free. If you are familiar with Linux, [OpenVPN](http://openvpn.net/) server is the "market leader". Windows can be a [VPN server](https://web.archive.org/web/1/http://articles.techrepublic%2ecom%2ecom/5100-10878_11-5805260.html) with no additional software on the server or on Windows clients, but I have never used it and would hesitate to because of my unwillingness to expose Windows to the internet.
Also, a [similar question has an interesting answer](https://serverfault.com/questions/12008/cheap-and-easy-solution-for-vpn) .. flash the router with dd-wrt, an open source firmware that includes OpenVPN. Note that I [recommended](https://serverfault.com/questions/12008/cheap-and-easy-solution-for-vpn/12044#12044) Astaro there as well!
Q2 (Least Headaches): Astaro is **really** easy to manage. I have also used Cisco and SonicWall VPNs and found them more difficult for the users and to administer. And, an Astaro appliance will be deployed and running in a tiny fraction of the time it will take to roll your own, or even to flash a router!
I think my opinion is clear! | If you have skilled systems/network admins certainly OpenVPN can be the solution you are looking for.
It will require the users to be provided with a certificate and a small client to be run on their clients.
One the certificates are created there is no maintenance needed during the product lifetime.
OpenVPN is free and well known, you could run a hardened, Linux box to host the server.
Don't forget the security aspects of having user connecting externally to your network. |

141,069 | I'm building a 2D game where the sole interaction of the player is rotating what they can see (this is currently the camera, though it could be the world) by plus or minus 60 degrees.
My current approach has their input rotating the camera. The issue I'm having is that I'm finding it impossible to keep track of how many degrees they've rotated it, since the camera is rotating and losing its initial position.
(I'm using libgdx, however, I think this problem is framework independent.)
**Edit:**
To help with the understanding, let me provide an example. Picture yourself in a school playground. You want to turn 90 degrees. To help you keep track, you mark the ground with the chalk in your hand. Turning 90 degrees is now easy since you have a reference point.
Now imagine you're in space and trying to do the same thing. Instead of chalking the ground, you chalk yourself. It's now nigh impossible to know how much you turn by when you do. | 2017/05/14 | [

1,181,370 | I am looking into building an access database that will replace a very frightening combination of excel spreadsheets that are linked together. The files for the current spreadsheet system are located on our Windows Storage Server, which has a mapped drive to the directory they use. Multiple users access this system as it host inventory, ingredients used in each product and pricing for everything. I believe using a database is a MUCH better Idea. As I am visioning it, If i split the database it would give me a front and back end. allowing multiple users to access and make changes at the same time, With out Corruption! woo-hoo!!!
Is this correct? and has anyone implemented this? did the end user find using the database easy enough? any problems with this that i did not for-see. I have read that it is also possible to have the front end locally on the users computers. True/good?

] | Access works very well for small offices, if it is set up properly. The database must be split, with each user having a copy of the front-end. This does not mean that each user needs a full copy of Access, the runtime version is sufficient. 2007 runtime is free (<http://www.microsoft.com/downloads/details.aspx?familyid=d9ae78d9-9dc6-4b38-9fa6-2c745a175aed&displaylang=en>)

That said, Access and Multiple Users = disaster waiting to happen as the number of multiple users goes up. You should seriously consider switching over to SQL Server Express for the backend. You can use Access forms / reports for the front end, linking the tables to the SQL Express Server.
I have done this type of split, but I only do it where there are VERY few people that would hit it at the same time. There's a copy of the database that houses all the UI things (forms, reports, etc) and the data lives in a different copy, all the tables are linked together. It works fairly well, but again I would NOT TRUST ACCESS with more than a few people hitting it at the same time.
I'll leave it to the rest of the SO community (assuming it gets migrated) to go from there. |

] | The kissing of the priest's hand in the Coptic Church is for the reasons that
1. He is a chosen vessel by God and receives a special grace given by the priesthood. He is the one who administers the Holy Eucharist to the people. His hands touch the Body and Blood of our Lord Jesus Christ, therefore, his hands are made holy.
2. It is a sign of respect and reverence to the priest who is considered a father figure.

Furthermore, His Grace Bishop Youssef, Bishop of the Coptic Southern Diocese of the United States says
>
> We kiss the hands of bishops and priests because in the context of the Divine Liturgy, the hands hold and distribute the holy Body and Blood of our Lord, God and Savior Jesus Christ! This is an enduring and centuries old tradition in the Eastern Christendom that has a purely metaphorical connotation; of course, this is not to leave out an underpinning element of paternal respect and affection as well. Kissing of the hands is also done amongst clergy. The blessing of the priest has a marvelous efficacy as being an exercise of the mysterious power with which he is entrusted. Through the prayers offered by the priest, the Holy spirit changes bread and wine into the Body and Blood of Christ. The priest bestows special sanctity upon Christians and upon the objects. The hand of a priest is, therefore, an instrument for imparting Divine Grace. For this reason Orthodox Christians throughout the centuries customarily kiss the hand of their priest.
