5,289 | * So far, [Siphon](http://code.google.com/p/siphon/) is the best [SIP](http://en.wikipedia.org/wiki/Session_Initiation_Protocol) app I've tried.
* [MobileVOIP](http://itunes.apple.com/us/app/mobilevoip/id362528311) and [TruPhone](http://www.truphone.com/iphone) are very nice too (and don't need jailbreaking).
* Other apps offer at least some SIP features such as Nimbuzz, Fring, Viber and even Skype.
* Apple's FaceTime audio clearly is an option for some
While I have all of these, I hardly use any of them, for a variety of reasons.
I'm looking for a more ideal third party app that should:
* Integrate with both Address Book and the iPhone's native recent calls
* Replace phone.app and load rapidly to place phone calls
* Have [international number support](https://apple.stackexchange.com/questions/5223/using-international-phone-numbers-on-iphone)
* Allow [call recording](https://apple.stackexchange.com/questions/731/is-an-iphone-call-recorder-theoretically-possible/)

] | I've used [Acrobits SoftPhone](https://www.acrobits.net/products/retail#tab_softphone) (link goes to their site, iTunes link below) for some time, thought admittedly very sparsely and only for the simplest of use cases, so, much of this is taken from their site.
Use the OS' Address Book: **Yep**, it maintains it's own "quick list" (favorites) however.
and global Recent Calls list: **Nope**, maintains it's own (pretty sure this one is impossible anyways, "private APIs" and all that).
Load as fast as Phone.app: I call this subjective, because Phone.app is always running, which gives it an inherit speedup compared to anything else. Acro's SoftPhone does support the VoIP backgrounding, and even push, so you can "Swipe To Answer", but it still **takes at least a couple seconds** to do. (At least that's *how it feels*, comparatively speaking.)
International Number Support: I think this is not so much a client feature as much as it is a feature of your server you SIP register to. This one is **unknown** to me as I've never attempted to call an international (outside the US) number.
Allow Recording: **Yes**. Upon tapping the record button, a voice announcement is played, and then conversation is recorded and able to be replayed from the app.
Skype: **Nope**
Google Voice: **Yep**, but to what extent, I am unsure. Per their website:
>
> GoogleVoice users: Though we have integrated GoogleVoice, Acrobits Softphone's main use is as a SIP client. You can setup Acrobits Softphone to initiate GoogleVoice calls through other types of numbers, but to get the full functionality of Acrobits Softphone, you need to have GoogleVoice linked to a SIP Account.
>
>
>
Rest: If it's SIP, it should work.
Bonus: It supports ZRTP. Zimmerman's encrypted RTP protocol for SIP calls. Free for incoming calls, in-app purchase for initiating calls using it.

] | I just tried several *free* softphones and I liked [Zoiper](http://www.zoiper.com/en "ZoiPer home page") the best, but since our Asterisk server is configured with very peculiar prefix rules I cannot use it. It supports native address book integration, call recording, various audio and video codes... pretty cool, if only it would allow custom rewriting rules :(
As strong second best I decided to use [Join softphone](https://itunes.apple.com/us/app/join-softphone-voip-sip-client/id566525840?mt=8 "Join App Store page"). It does integrate with addressbook and allows complex rewrite rules. It promises that it does call recordings, but I could not get it to work properly. What really puts me off with Join is rather confusing UI with too many colors and drop shadows. It really does not work well on mobile screen. Maybe desktop but not small screen such as mobile. But it was only feature full free solution I've found. | General problems when using Softphone app are:
1. Complex network conditions in mobile networks (i.e. NAT). Not all VoIP servers can properly work with NAT.
2. Limited bandwidth. Is is impossible to use high nitrate codecs in 3G networks. But many operators does not support modern codecs like Opus.
3. Problems with incoming calls. To receive calls phone must be connected to the server. It drains battery.
This is not ad, but try our solution:
[www.sipmobile.org](http://www.sipmobile.org)
We resolved this issues. You can use our Softphone in mobile 3G networks with good voice quality. If you have LTE or WiFi, video calls are available. Softphone for iOS can be switched off and receive calls with push notifications (of course only in our domain). |

112,688 | I have a website where the user will be able to see charts created based on filters that they have chosen. At the top of the page are several filter topics that, when clicked, expand a sort of dialog underneath (I am actually perverting Bootstrap's dropdown element for this purpose for the moment) where they can make specific choice (e.g., region, gender, etc., and some slightly more complex ones).
The dialog will have two buttons at the bottom, "OK" and "Cancel" - if you hit OK, the dialog closes and shows an abbreviated version of your selections under the filter label; and if you hit Cancel, the dialog closes and reverts to whatever the filter was at originally (that is, before your latest changes that you "canceled"). Then there is a button to trigger implementation of the filters you've chosen and change the charts.
However, the default behavior of these dialogs (and something that I think a lot of users probably expect, but I could be wrong) also allows people to close the dialog by "clicking off" - that is, clicking the page somewhere outside of the dialog box.
The question we have is: should this behavior trigger "OK" or "Cancel"? Or maybe we should disallow this behavior altogether and force them to choose one of the buttons in order to close the dialog.
I was thinking I would expect that the next time I opened the dialog, it would show the selections I had made unless I clicked cancel (kind of like how in some browsers, if you are filling out a form and click a link off of the page, but then use the back button, you find your answers still filled in). My colleague expected this behavior to cancel whatever was put in. I think we are too close to this so I appreciate any feedback. Thank you. | 2017/10/13 | [

] | In this case it is wise to stick to conventions; clicking outside of a modal will act the same as the cancel option. Enabling this behaviour will help people who rely on this principle on other websites, while not harming those who never use it.
Remember, it's a good thing to label your call to actions appropriately - OK and Cancel are context dependant. They force a user to read everything before these actions make sense (and even then it can be dubious what lies beyond the click).

Absolutely, if the capacitor ground isn't connected to the IC ground, it can't do its job of providing a low-impedance path between those two nets.
If you want to think of it in terms of ground loops, think about it this way:
If the capacitor wasn't there, then when the IC draws current it would have to draw it from the power supply itself, or from a bulk capacitor. In either case, the part supplying the current would be much further away.
That means the current would flow in a loop from the power supply to the IC and back to the power supply. That would be a much larger loop than from the very close-by bypass capacitor to the IC and back.
So what the bypass capacitor is doing is shorting out a large loop by making a small one. Which reduces the emissions from the loop and reduces the inductance of the loop, causing less voltage ripple as the current demand changes. | It's important to have any required high frequency decoupling capacitor as close to the IC pins as possible. That capacitor supplies short bursts of current to the chip (generalism alert) that would otherwise be provided from a capacitor a bit further away and fed down copper tracks. Keeping tracks short means keeping EMI and circuit cross talk down.
Some chips will just not perform if their respective decoupler caps are not close up at the chip. We're talking 100 nF and under here to fall into this type of category. |

I'm admittedly a bit confused on when "Not An Answer" (NAA) flags should be applied, so I hope you'll bear with me on another question related to question scoping.
Let me suggest, for the purposes of this question, that we broadly define the term "scope," so that it includes every way that a questioner expresses the characteristics of desirable answers to his question. Here are some examples of "scoping mechanisms":
1. **Key concept**. This is the point of the question. It could be a word/phrase (what does X mean?), a biblical passage (how is X interpreted?), a concept (who believes X?), and a number of other things. But without it, there is no question.
2. **Perspective**. The perspective from which answers should come. It could be a tradition/denomination (Roman Catholicism, Methodism, Mormonism), or a cross-denominational view (young-earth creationism, pacifism, non-trinitarianism). The above linked Meta post deals exclusively with this point.
3. **Type**. Examples of this include overview and biblical basis.
4. **Time**. Not only words like *earliest* or *first* in "what was the earliest instance of X?" but also limiters like "20th century" or "early church" or "Reformation period."
5. **Geography**. Relevant in terminology questions, like "What does word X mean in the United States?," and also for specifying regional movements or beliefs, like "When did X begin in Latin America?"
6. **Sources**. This can include specifying an individual person, as "What do person Y's writings say about X?," or a category, like *scholastics* or *reputable theologians* or *published bible commentaries*. Similar to Perspective, but here we limit to which *types* of sources from a particular view are relevant to the question.
I'm sure I'm missing some other possibilities; feel free to suggest more. If you feel that I have inaccurately grouped anything, let me know and I'll split things up.
Now let's start applying this to my question regarding NAA flags. I know that, at least in practice, there are many factors *besides scope* that might go into the decision to flag an answer as NAA, and, by extension, to accept or decline such flags. I'll ask about the legitimacy and relative importance of those factors in another question. Here, however,
**I want to know which of the above scoping mechanisms ought to be considered when flagging as NAA or evaluating NAA flags. If more than one should be considered, are any of them more important than others?**

] | One important thing to keep in mind is the authors intent is the main thing to consider. Being blatantly wrong isn't a valid reason to delete according to the Stack Exchange model. for example, if someone asks for the Catholic perspective on original sin and someone answers "I heard it is blah blah" and doesn't cite any sources that is a poor answer in general. But, even it is blatantly wrong, it is still an answer. It should be downvoted, not deleted. In contrast, if someone answers "The Baptist perspective is blah blah" and cites tons of sources, it is still NAA and deserves deletion. If it unclear what the author was trying to do, we should probably assume that they were attempting to answer the question in good faith and simply did a poor job of it. Having your answer deleted is pretty jarring and shouldn't be done lightly.
With that in mind, it would hard for answers to something like "what is the first X" or "what does this mean to Y" (#4, #5) to be NAA - they can easily be wrong of course, but it would be hard to determine the author wasn't attempting to answer probably. Classic NAA stuff (follow up questions, related thoughts, thanks, etc.) is of course easily deleted (#1). Denominational scopes (#2) are fairly obvious too - usually off-topic answers will blatantly say they are arguing why the requested perspective is wrong. I doubt #6 will arise - would people really answer "what did Luther think about X" with "Calvin believed Y"? I would hope not, but it would be obviously NAA if they did.
I am also against deleting "overview" answers (#3) that don't outline all possible positions. An answer that outlines only one or two views, but clearly specifies that view(s) and gives significant details is a valid (partial) answer to an overview question. Indeed, such answers can be quite useful; useful content, not some strict adherence to rules for the sake of it, should really be what we are aiming for. Biblical basis is kind of a gray area - such answers should ideally cite Bible verses, but answering "theologian X argues Y based on his understanding of the Bible" is almost certainly a valid answer.
So my conclusion, is pretty much the same as El'endia Starman's comment - **Failing to meet #1,2, or 6 is normally a valid reason for the NAA deletion. Failing to meet #3,4, or 5 rarely is because such failures will normally just be weak (or even wrong) answers, not people ignoring the requested scope.** | This may qualify as NAA to this question :), but I wanted to say we shouldn't be rewording old questions that no longer fit the site scope and then deleting the old answers. It seems like 1-2 of these questions is bumped each week and while we've closed most of them, we did reword a few. I don't think deleting once valid content just to keep a question open is a good idea. |

**Abstract:** The classical Fraïssé construction is a method of taking a direct limit of a family of finite models of a language provided the family fulfills certain amalgamation conditions. The limit is a countable model of the same language which can be characterized by its (injective) homogeneity and universality with respect to the initial family of models. A standard example is the family of finite linear orders for which the Fraïssé limit is the rational numbers with the usual ordering.
We present this classical construction via category theory, and within this context we introduce the dual construction. This respectively constitutes the Fraïssé colimits and limits indicated in the title. We provide several examples.
We then present the projective Fraïssé limit as a special case of the dual construction, and as such it is the categorical dual to the classical (injective) Fraïssé limit. In this dualization we use a notion of model theoretic structure which has a topological ingredient. This results in the countable limit structures being replaced by structures which are zero-dimensional, compact, second countable spaces with the property that the relations are closed and the functions are continuous.
We apply the theory of projective Fraïssé limits to the pseudo-arc by first representing the pseudo-arc as a natural quotient of a projective Fraïssé limit. Using this representation we derive topological properties of the pseudo-arc as consequences of the properties of projective Fraïssé limits. We thereby obtain a new proof of Mioduszewski’s result that the pseudo-arc is surjectively universal among chainable continua, and also a homogeneity theorem for the pseudo-arc which is a strengthening of a result due to Lewis and Smith. We also find a new characterization of the pseudo-arc via the homogeneity property.
We continue with further applications of these methods to a class of continua known as pseudo-solenoids, and achieve analogous results for the universal pseudo-solenoid.

Using REST, I populate a list onto a page. I want the page to refresh the list without refreshing the page whenever a new item is added to the list.
**Current Shoddy Solution**
I have 2 GET requests. 1 is to populate the list onto the page, the other is to check the ID of the TOP item. Request 2 runs every 5 sec using setInterval(). I then compare the IDs of the newest item and the last one posted on my page (embedded the ID into the ID tag and then retrieved). Using an IF, if the newest added item ID is not equal to the latest item on the page, I run GET request 1 again to populate the new data on the page.
This is working well from the end user's perspective and doesn't seem to be taxing resources too much but, I feel like running a GET request, even if it's lite, pulling the only top item and only the ID column, is still a GET request every 5 sec.

42,888 | Assuming a flat bottom wing moving through the air at say 50km/h and at zero degree angle of attack, what will be the likely airspeed above and below the wing?
I know this will be affected by camber and maybe wing chord too. But is there like a proportional estimate for specific wing camber?
I haven't got much knowledge about wing maths, but a formula would be appreciated.
Applying Bernoulli's equation requires the relative airflow above and below the wing. The things is, I'm trying to experiment with the fact that given atmospheric pressure, the two different airflows, and the wing area, one can actually determine the pressure difference between the top and bottom surface using Bernoulli's equation and also the total force holding the plane up by getting the product of the pressure difference and the wing area. So what I'm trying to do is estimate the lift force on my theoretical airplane model at a particular wind speed. I want to use this to estimate the minimum airspeed required for normal flight 'without flaps'. | 2017/08/11 | [

] | The short answer is that it is possible, by way of knowing the [pressure distribution](http://docs.desktop.aero/appliedaero/airfoils1/AirfoilPressures.html) and applying the Bernoulli equation to relate the pressure and the velocity.
More specifically to your question, I'm not aware of any published correlation between camber and air velocity (nor do I think it'd have much practical application), but you could come up with your own by running a variety of geometries through [XFOIL](http://web.mit.edu/drela/Public/web/xfoil/) for a given airfoil geometry (maybe a [Clark Y](http://airfoiltools.com/airfoil/details?airfoil=clarky-il) of varying camber for a flat-bottomed design) and applying Bernoulli on the calculated pressure distribution for whatever freestream atmospheric conditions and chord length you want.
Another note: You asked specifically about a wing, not an airfoil. A wing will have lots of other effects contributing to variations in velocity over its surface; there is no easy way to account for all of them. | Applying Bernoulli's equation requires the relative airflow above and below the wing.

249,048 | We have a nice creek going through our lot and a renovated barn on the other side. We have a creek crossing that was designed by an engineer. While it didn't have to be permitted (since it wasn't on the road to the actual dwelling), it meets the requirements for that, so the road surface is 1" above the 100 year floodplain and the culverts are designed to allow the full flow of water needed during a 100 year rainfall event.
[](https://i.stack.imgur.com/qfonz.jpg)
Some general numbers: The crossing surface is 6'1" above the creek level and there are three 30" culverts that pass through. This is what was required by the original design from the engineer. (The picture of the crossing is from the downstream side, if it matters.)
At this spot where the crossing is, the banks are high and the "overflow" area is narrower than farther down where I want to put a footbridge. Since we moved in here, in 2017, we have seen three 100 year rainfall events (two of those were in one day, one pre-dawn and one in the evening) and a 700 year rainfall event. During and after the rainfall, I go down and check on this and several other areas to see how they're holding up, then I go and check after the rainfall as well. Whenever I have looked at the crossing during these massive rainfall events, the water is always going over the top of the crossing and the water level on the downstream side of the crossing is significantly lower than on the upstream side. It's always like this:[](https://i.stack.imgur.com/KsJta.png)
When the flooding does not go above the top of the inside of the culverts, there still seems to be a higher water level on the upstream side, but it's difficult to tell for sure.
Is the lower water level on the downstream side normal under the circumstances, or is it happening because debris is clogging the culverts nor not going through it easily and creating a backup that forces the water to rise up and go over the top of the crossing? In other words, during a flood that's just over a 100 year rainfall event, is it more normal for the water level to be the same on the upstream and downstream sides, like this:
[](https://i.stack.imgur.com/hUdaK.png)
Which is normal for these higher level rainfall events? Is the crossing enough of an obstruction that it raises the water level on the upstream side even though we're using the specified sized culverts? Or should the water level be the same on the downstream side as well as the upstream side?
It makes a difference in what I can do with building a footbridge downstream. If the water level should be the same, I have to build a sturdier footbridge. If it's normal for it to be lower after something like the crossing, I can go with a smaller footbridge and I have ideas I can use to make it survive flooding more easily.
---
Addendum: After seeing responses, I think I need to add that when I'm talking about putting in a footbridge, I don't mean a structure nearly as expensive as this. I'm thinking of just a wooden bridge that rests on footings on each side. | 2022/05/10 | [

] | We can't possibly answer your direct question. It totally depends on terrain downstream, which
What you have is a dam. Specifically a "dry dam". An earth-filled dam with a stone or concrete skin. The two stone walls were never imagined to resist side-force from the impounded water, and would fall right over without the earth.
The problem is, you are going to lose the earth, due to **head-cutting** from the flow of water. See bright blue arrows.
[](https://i.stack.imgur.com/j0BA1.png)
*That is a dam.*
In 2017, the Oroville dam was famously backed into a corner when their river valve outlet was down for repairs, and the main spillway broke, taking out the generator power lines. They were down to the broken spillway and the never-tested emergency spillway, and they [learned all about head-cutting](https://www.youtube.com/watch?v=jxNM4DGBRMU).
Anyway, you have risk of head-cutting in all the places I marked - churn over the first wall digging up the gravel that supports the first wall, churn after the second wall undermining its foundation, and leakage between wall and culverts eroding and causing liquefaction in the fill material. This would result in catastrophic failure of the dam, releasing all the impounded water in a tidal wave.
The cure for this is a proper "emergency spillway" so that overtopping occurs in a location of your choosing, over surfaces built to endure it. Not like Oroville lol. That would be a lowering of your road at a particular point, so that overflow water will divert through that low spot and never over-top the dam.
Anyway, as far as your foot bridge, the same issues will arise with over-topping, unless you provide considerably more passage under it. | IMHO, the engineer screwed up! The 100 year flood plain (where the water from the creek will go during a once in a hundred year flood) is determined prior to the damming caused by the culvert - that is, where the water will spread out if the crossing/culvert was not there. If my property were upstream of that culvert and started suffering flooding due to the natural water flow being impeded by the crossing, there would be a major lawsuit to deal with.
**Note on the Footbridge**
A simple footbridge, supported by footings on each bank is not going to impede water flow (until the water reaches the level of the footbridge). So I would not think something like this would impact the 100 year flood plain determination.
**A Case Study**
For an interesting case look up "Ellicott City Floods". Ellicott City is an old mill town in Maryland that experienced 2 1,000 year floods in 2 or 3 years, 2016 & 2018 I think. One of the reasons given for the extensive flooding that occurred is because the major streams that flow through the town have had buildings erected in their natural flood plains. According to one of the engineering reports I read, these buildings prevent the waters from flowing out onto the flood plain and act as a dam (just like your roadway culvert) and causes water to back up hill into the town.
Here's [some of the video](https://apps.npr.org/ellicott-city/?fbclid=IwAR2IRXvAA3GKLyhfFgfxo4bH_MK61GmOKxWN8pvMcH0w-l137ByZSYIJULY) from those floods. |

No, it's not a "MUST." However, if you don't know how to program, you will become easily frustrated. Let's think about it for a second, what's malware reverse engineering? Its the process of taking samples (binaries) or other forms of malicious code and trying to understand how the code was written, what its purpose and how it achieves it.
If you don't know how to program you are going to find it very difficult to reverse back code.

I would not recommend this tool, to begin with. You should probably start with a more fundamental approach, such as I described [here](https://reverseengineering.stackexchange.com/questions/20984/most-efficient-way-to-begin-analyzing-malware-binary/21009#21009).
Also, you probably want to go over the following StackExchange threads and for tutorials and learning paths:
* [Becoming a malware analyst](https://security.stackexchange.com/questions/36331/becoming-a-malware-analyst)
* [How to get started as a malware analyst](https://security.stackexchange.com/questions/91309/how-to-get-started-as-a-malware-analyst) | It's always good to have a big goal in mind, and with RE, the beginning stages of this pursuit may seem overwhelming. I see a lot of great answers here so just want to chip in with my take on what your immediate next steps should be.
I agree, asm is a must. There's pros and cons for choosing a particular one but I suggest choosing one and really stick with it, and stay with a particular syntax so you can walk away from that stage in your learning feeling confident. Don't be afraid to learn C/C++ at the same time, they can be used to understand each other! A youtuber named "What's Creel" takes this approach in his assembly tutorials.
I also want to encourage you to "go where your resources take you." If you find a great tutorial using radare2, forget ghidra and ida for now just go with the teacher that's in front of you and that you like at that moment. To me this is true for systems as well. If you are watching John Hammond complete CTFs on youtube, download an Ubuntu iso for a virtual machine and follow along. Nothing beats hands on learning, and if you are exhausted learn to rest effectively as well! Eat well, exercise, get enough sleep etc.
This brings me to my last point, know thyself! If you know what type of learner you are, seek those resources so you can learn more effectively. Personally I'm a mixture of visual, and social. That social piece really helps me whether it's listening to 2 people discuss something on a podcast or talking with someone myself over coffee, those conversations nail home the concepts I'm trying to comprehend. Some people can just read a manual and learn from that, or experiment with code till they understand what's going on. Whatever it is, just embrace and multiply it so you can avoid the (ultimate) feelings of despair technical fields like this have. These different approaches to learning might also differ depending on your mood or environment, so don't forget to be flexible!
Here's a list of resources, some directly support the RE / malware goal you've stated, and some indirectly will help you be it supporting technology knowledge or technical creativity.
Podcasts
========
* Security Now with Steve Gibson
* Software Engineering Daily
* Kubernetes Podcast
* CppCast
* Darknet Diaries (creativity!)
YouTube tutorials
=================
* Me, [reading the intel manual](https://youtu.be/_K_9yBHkXEE) and asking questions, beats reading alone
* Liveoverflow, very professional and engaging, start with his [Binary Exploitation series](https://youtu.be/iyAyN3GFM7A)
* Conferences, Conferences, Conferences. I learn so much from these talks maybe start with [Cpp con 2018](https://youtu.be/HddFGPTAmtU) but you'll want a really good handle on the basics first

youtube is just a treasure trove, I'm sure I'm forgetting a ton...
Misc / Passive learning
=======================
* TinyCards app, I made three decks of x86 assembly instructions
* SoloLearn and Enki app, just basic programming language intro, q&a formart.
* Reddit, the AskNetSec subreddit seems to have the highest quality discussions
Active Learning
===============
* Do! Create! Students just learning programming, hardware, networking, etc. will often complain to me about not understanding and when I ask what they've done the only things I hear are passive. You can't learn this stuff without getting your hands dirty, even if that means writing down your thoughts or questions (they don't need to be answered right away...) but if you can write programs or test malware in a VM yourself that'd be even better.
* Have a github account
* Make a learning journal for reflection
The last thing I'd like to say, and I'm not trying to discourage you at all, but try to get a strong grasp of the fundamentals, doing so should accelerate your progress. I'm often reminded of this picture when I hear students talking about their tech dreams and 1 month into class I see they don't have the mental stamina to work on something for longer than 10 minutes, in this case though just replace "bug hunting" with "reverse engineering," because they are both long term goals:

The Mylar that they're made of is surprisingly tough and I doubt that it would rip or tear, but I would expect it to develop plenty of very small punctures and begin to lose its aluminum coating (possibly making a glittery mess) within a few uses. It would be worth picking a brand and testing them out before committing to it.

42,853 | I have been looking to develop some metrics for a UX project (which was also a [question](https://ux.stackexchange.com/questions/37933/metrics-for-measuring-user-engagement-for-web-applications) I posted previoiusly), and have been reading about the [Kano](http://en.wikipedia.org/wiki/Kano_model) model and how it maps to different user behaviour/expectations. I was wondering whether it is practical to dissect the functions/features of a product based on user perception about the presence and absence of features (ref [here](http://www.mountaingoatsoftware.com/articles/i-didnt-know-i-needed-that)) and tallying up to see if there were more features that generated excited rather than expected or dissatisfied experiences.
There have been proposals of frameworks for evaluating user experience (e.g. Google's [HEART framework](http://research.google.com/pubs/pub36299.html)) but these models do not provide actual metrics or mapping to the components or categories that make up the whole user experience which we want to capture. I have found that the Kano model is one starting point from mapping product functions and features to particular aspects of the user experience, and would like to look for other ways to start filling in the rest of the gaps.
The question is, can the features of a software product or service be classified as one of the three categories and weighted to provide a value/metric for how users feel about a product.

No, because you certainly have many features and you need 2 questions for each to get the Kano state of it. That will be a terribly long survey, only to get the satus quo of your feature satisfaction.
UX is more than product value and satisfaction, so I recommend to invest your energy into a concept of metrics, which gives you insights where to step further. |

**Derive a metric from Kano Analysis?**

You could, however it would be a coarse metric, and it would more properly describe how users feel about the potential of the product.
And it really should be two metrics.
The Kano model is a variation on [Herzberg's Two Factor theory of satisfaction](http://en.wikipedia.org/wiki/Two-factor_theory), which states that there are certain factors that cause satisfaction while a separate set of factors cause dissatisfaction. That is, satisfaction and dissatisfaction act independently of each other.
To quote Jesse James Garrett: ["Reduction of misery does not equate to increase of joy"](https://twitter.com/jjg/status/360815958073413632).
So, the two metrics you want to extract is the overall impact on satisfaction, and the overall impact on dissatisfaction.
If you were to try to distill this down to just one metric you should give at least a 3x weighting to all the features which appear to be baseline (aka [basic, must-be, threshold, et al](http://en.wikipedia.org/wiki/Kano_model#Threshold_or_Basic_Attributes)). See this [TechCrunch article](http://techcrunch.com/2013/05/19/androids-design-principles-and-the-calculus-of-the-human-pleasure-response/) for references to research justifying the 3-5x weighting to give to negative things.
Also, not all baseline features have the same degree of impact, and also for different numbers of users. Kano analysis can help with the latter easily, but the former is only implied in the method.
You could ask an extra question on each feature to evaluate relative impact, or incorporate [Choice-Based Conjont analysis](http://www.mdtmag.com/articles/2013/07/making-old-%E2%80%98new%E2%80%99-again-prioritizing-medical-device-features-using-kano-model-analysis). It's not as important as you might think, as nett importance would be determined by multiplying the relative importance by the proportion of users that feel that way. If you have 10% who think feature X is really, really, really nifty ... that's probably not as important as 80% who think feature Y is kinda, yeah, mostly nifty.
It's important to note though that the metrics from Kano Analysis only reflect *potential* for satisfaction and dissatisfaction. The model is built on the idea that the user's response to a feature varies according to the degree of execution of the feature, with the three main Kano classifications describing the shape of the response line.
So, the classifications and thus the metrics you get from Kano analysis won't tell you how good your product actually is (you need to use other survey methods to get that). However, it will tell you if there's more you can do, and also help you focus your research efforts appropriately.
**Track and monitor over time?**
--------------------------------
>
> And is it practical to track and monitor this over the life-cycle of the

>
>

Yes. You would gather the quantitative data for Kano modelling by surveying a random sample of your users, and you could do so periodically and thus monitor it that way (that's the beauty of statistical sampling). *Just don't keep surveying the exact same sample each time.*
If the length of the survey worries you then you can also survey different random samples of users, each with a short sub-set of features. The total number of survey participants would go up of course, but the effort requested of them individually is still low. This works with Kano Analysis since each feature is evaluated independently of others.
You could also refine the set of features you survey over time. If for example you find that 99% of respondents consider Feature X to be of no importance then simply stop asking about it. Also, if your team has come up with some genius idea for a new feature you can throw it in the mix and see it mapped against the other features. If it's a stinker, best to find out early and drop it before expending any further resources on it.
Importantly, you *should* monitor the Kano classifications of your features over time. Part of the Kano model discusses the fact that feature classifications drift over time, starting out as [Delighters](http://en.wikipedia.org/wiki/Kano_model#Excitement_Attributes), then become [Performance](http://en.wikipedia.org/wiki/Kano_model#Performance_Attributes) features, before settling down as [Baseline](http://en.wikipedia.org/wiki/Kano_model#Threshold_or_Basic_Attributes) features.
You want to know when a Delighter becomes a Performer because according to the model that feature will not only contribute to satisfaction but insufficient implementation will now contribute to dissatisfaction. Now, it's important to improve the feature, and not simply rely on mere inclusion to drive overall satisfaction. (Remember when we were all excited about our phones having a camera built in, despite how crappy they were? Phones in cameras are no longer a delighter, they need to be of quality.)
Similarly, when a feature fades from being a Performer and becomes a Baseline you want to reposition the feature - it's no longer something that should be trumpeted and it shouldn't sing and dance .. it should simply do what's required and then get out of the damn way. No fancy gift-wrapping.
You also want to look into whether particular large changes in the market landscape are impacting the importance of various features - a given feature might suddenly accelerate its drift from one classification to another, or even simply just jump right on over to the next classification. Look to geo-political shenanigans for example situations.

Let me wrap up by describing a couple of examples of how I've used Kano Analysis.
**Case study 1:**
-----------------
We were building a very complex online application, and there was the usual overly-long list of feature requirements. We needed a way to get a handle on which features are absolute must-haves, and which we could delay for later.
So, we worked up a list of 41 features and then used a panel service to recruit 45 participants for a Kano survey, offering a sizable incentive as compensation.
We crunched the numbers, and this was the result:
The horizontal axis is the proportion of participants that would negatively react to an insufficient implementation of each feature, while the vertical axis is the proportion of participants that would be positively affected by the feature.
* The grey dots are features for which most respondents didn't consider important for either satisfaction or dissatisfaction. That list of features got dumped into the backlog real quick. Some were borderline, and we kept an eye on them for later.
* The blue dots are the Baseline features. Again, we simplified the design to focus on just the core functionality of each. *What would it take to ensure the users would not hate us?*
* The green dots are the performer features. Those we knew we'd need to pay further attention to. They would have to meet the basic expectations of the users, and from there any further refinement would provide a satisfaction payoff.
* The yellow dots are features most respondents considered as delighters. Those features we simplified and scaled back the designs. We also cherry-picked the ones that would be drop dead simple to do and which were real differentiators, knowing that most users wouldn't even notice the other delighters were missing (by definition). The standard we had to reach was *What would it take to get the attention of the users?*
We didn't distill all that data down to a single metric as we were already getting a lot of value out of the map as is. We could have, if we wanted a very high-level strategic metric (similar to how [NPS](http://en.wikipedia.org/wiki/Net_promoter_score) is a high-level metric).
**Case study 2:**
-----------------
This was a smaller and shorter exercise. We had conducted a series of stakeholder workshops and user workshops, and from those we developed a list of ideas for features for a new website. As you know, small samples combined with group dynamics meant we simply couldn't rely on the enthusiasm of the workshop participants to define the importance of each feature, and so we ran a Kano Survey for validation.
This time we used [ethn.io](http://ethn.io/) to do the recruiting for us. We installed the javascript onto the client site and in less than 3 days we had 73 qualified participants.
This is the graph of the analysis:
See that grey dot down in the bottom left? That was a feature everyone in the workshop thought would be pretty nifty. Turns out [computer says no](http://www.youtube.com/watch?v=WOdjCb4LwQY).
The position of a few other features also proved to be food for thought. | Maybe not a direct answer to your question but thoughts that I hope can add some value. Anyway, I'd love to see some more answers to the question.

You could, however it would be a coarse metric, and it would more properly describe how users feel about the potential of the product.
And it really should be two metrics.
The Kano model is a variation on [Herzberg's Two Factor theory of satisfaction](http://en.wikipedia.org/wiki/Two-factor_theory), which states that there are certain factors that cause satisfaction while a separate set of factors cause dissatisfaction. That is, satisfaction and dissatisfaction act independently of each other.
To quote Jesse James Garrett: ["Reduction of misery does not equate to increase of joy"](https://twitter.com/jjg/status/360815958073413632).
So, the two metrics you want to extract is the overall impact on satisfaction, and the overall impact on dissatisfaction.
If you were to try to distill this down to just one metric you should give at least a 3x weighting to all the features which appear to be baseline (aka [basic, must-be, threshold, et al](http://en.wikipedia.org/wiki/Kano_model#Threshold_or_Basic_Attributes)). See this [TechCrunch article](http://techcrunch.com/2013/05/19/androids-design-principles-and-the-calculus-of-the-human-pleasure-response/) for references to research justifying the 3-5x weighting to give to negative things.
Also, not all baseline features have the same degree of impact, and also for different numbers of users. Kano analysis can help with the latter easily, but the former is only implied in the method.
You could ask an extra question on each feature to evaluate relative impact, or incorporate [Choice-Based Conjont analysis](http://www.mdtmag.com/articles/2013/07/making-old-%E2%80%98new%E2%80%99-again-prioritizing-medical-device-features-using-kano-model-analysis). It's not as important as you might think, as nett importance would be determined by multiplying the relative importance by the proportion of users that feel that way. If you have 10% who think feature X is really, really, really nifty ... that's probably not as important as 80% who think feature Y is kinda, yeah, mostly nifty.
It's important to note though that the metrics from Kano Analysis only reflect *potential* for satisfaction and dissatisfaction. The model is built on the idea that the user's response to a feature varies according to the degree of execution of the feature, with the three main Kano classifications describing the shape of the response line.
So, the classifications and thus the metrics you get from Kano analysis won't tell you how good your product actually is (you need to use other survey methods to get that). However, it will tell you if there's more you can do, and also help you focus your research efforts appropriately.
**Track and monitor over time?**
--------------------------------
>

Yes. You would gather the quantitative data for Kano modelling by surveying a random sample of your users, and you could do so periodically and thus monitor it that way (that's the beauty of statistical sampling). *Just don't keep surveying the exact same sample each time.*
If the length of the survey worries you then you can also survey different random samples of users, each with a short sub-set of features. The total number of survey participants would go up of course, but the effort requested of them individually is still low. This works with Kano Analysis since each feature is evaluated independently of others.
You could also refine the set of features you survey over time. If for example you find that 99% of respondents consider Feature X to be of no importance then simply stop asking about it. Also, if your team has come up with some genius idea for a new feature you can throw it in the mix and see it mapped against the other features. If it's a stinker, best to find out early and drop it before expending any further resources on it.
Importantly, you *should* monitor the Kano classifications of your features over time. Part of the Kano model discusses the fact that feature classifications drift over time, starting out as [Delighters](http://en.wikipedia.org/wiki/Kano_model#Excitement_Attributes), then become [Performance](http://en.wikipedia.org/wiki/Kano_model#Performance_Attributes) features, before settling down as [Baseline](http://en.wikipedia.org/wiki/Kano_model#Threshold_or_Basic_Attributes) features.
You want to know when a Delighter becomes a Performer because according to the model that feature will not only contribute to satisfaction but insufficient implementation will now contribute to dissatisfaction. Now, it's important to improve the feature, and not simply rely on mere inclusion to drive overall satisfaction. (Remember when we were all excited about our phones having a camera built in, despite how crappy they were? Phones in cameras are no longer a delighter, they need to be of quality.)
Similarly, when a feature fades from being a Performer and becomes a Baseline you want to reposition the feature - it's no longer something that should be trumpeted and it shouldn't sing and dance .. it should simply do what's required and then get out of the damn way. No fancy gift-wrapping.
You also want to look into whether particular large changes in the market landscape are impacting the importance of various features - a given feature might suddenly accelerate its drift from one classification to another, or even simply just jump right on over to the next classification. Look to geo-political shenanigans for example situations.

Let me wrap up by describing a couple of examples of how I've used Kano Analysis.
**Case study 1:**
-----------------
We were building a very complex online application, and there was the usual overly-long list of feature requirements. We needed a way to get a handle on which features are absolute must-haves, and which we could delay for later.
So, we worked up a list of 41 features and then used a panel service to recruit 45 participants for a Kano survey, offering a sizable incentive as compensation.
We crunched the numbers, and this was the result:
The horizontal axis is the proportion of participants that would negatively react to an insufficient implementation of each feature, while the vertical axis is the proportion of participants that would be positively affected by the feature.
* The grey dots are features for which most respondents didn't consider important for either satisfaction or dissatisfaction. That list of features got dumped into the backlog real quick. Some were borderline, and we kept an eye on them for later.
* The blue dots are the Baseline features. Again, we simplified the design to focus on just the core functionality of each. *What would it take to ensure the users would not hate us?*
* The green dots are the performer features. Those we knew we'd need to pay further attention to. They would have to meet the basic expectations of the users, and from there any further refinement would provide a satisfaction payoff.
* The yellow dots are features most respondents considered as delighters. Those features we simplified and scaled back the designs. We also cherry-picked the ones that would be drop dead simple to do and which were real differentiators, knowing that most users wouldn't even notice the other delighters were missing (by definition). The standard we had to reach was *What would it take to get the attention of the users?*
We didn't distill all that data down to a single metric as we were already getting a lot of value out of the map as is. We could have, if we wanted a very high-level strategic metric (similar to how [NPS](http://en.wikipedia.org/wiki/Net_promoter_score) is a high-level metric).
**Case study 2:**
-----------------
This was a smaller and shorter exercise. We had conducted a series of stakeholder workshops and user workshops, and from those we developed a list of ideas for features for a new website. As you know, small samples combined with group dynamics meant we simply couldn't rely on the enthusiasm of the workshop participants to define the importance of each feature, and so we ran a Kano Survey for validation.
This time we used [ethn.io](http://ethn.io/) to do the recruiting for us. We installed the javascript onto the client site and in less than 3 days we had 73 qualified participants.
This is the graph of the analysis:
See that grey dot down in the bottom left? That was a feature everyone in the workshop thought would be pretty nifty. Turns out [computer says no](http://www.youtube.com/watch?v=WOdjCb4LwQY).
The position of a few other features also proved to be food for thought. | Kano Model is representation of metrics to assess user satisfaction with a product. Satisfaction is very important measure but user experience is one step ahead of it. The historical evolution is from service quality --> Customer Care and Satisfaction --> Customer Experience. UX/CX is holistic concept which takes usability measures, aesthetic, emotions, cognition and experiences. In short, Kano Model is good as long as your focus is to gauge user satisfaction. But for user experience, you need more factors, otherwise your model will be confounded. |

No, because you certainly have many features and you need 2 questions for each to get the Kano state of it. That will be a terribly long survey, only to get the satus quo of your feature satisfaction.
UX is more than product value and satisfaction, so I recommend to invest your energy into a concept of metrics, which gives you insights where to step further. |

ASP.NET MVC 1.0 was released on 13 March 2009, not part of the .NET Framework, running on top of ASP.NET, which was then part of .NET Framework 3.5.
MVC's version did not correspond to .NET Framework/ASP.NET versioning. MVC went through version 2, 3 and 4 and ASP.NET MVC 5 was released on 17 October 2013. Meanwhile the .NET Framework went from 3.5 to 4.7, now 4.8 but will never reach a higher major version.
---
Then .NET Core started under the working title "vNext". It was .NET Core 1, then 2, then 3. .NET Core includes ASP.NET Core, which included ASP.NET Core MVC. This versioned along with its framework.
Now to prevent confusion, they didn't want to name the fourth version of .NET Core as 4, because that'd conflict (not on a filesystem level, but in the heads of developers) with .NET Framework 4. So they unified .NET Framework and .NET Core, and called it .NET 5.

] | I can think of a few things as proof that the shadows generated by the Stone really are dead:
**1.The second Peverell's girlfriend**
In the story of the Three Brothers, the second brother asks for the resurrection stone to bring back the girl he was going to marry. Here is the text as Hermione read it in Book 7:
>
> Meanwhile, the second brother journeyed to his own home, where he lived alone. Here he took out the stone that had the power to recall the dead, and turned it thrice in his hand. To his amazement and his delight, the figure of the girl he had once hoped to marry, before her untimely death, appeared at once before him.
>
>
> Yet she was sad and cold, separated from him as by a veil. **Though she had returned to the mortal world, she did not truly belong there and suffered.**
>
>
>
I know it's not that much to go on since it's a children's story, but it's something.
**2.What Sirius says in the forest.**
>
> "Does it hurt?"
>
>
> The childish question had fallen from Harry's lips before he could stop it.
>
>
> "Dying? Not at all," said Sirius. "Quicker and easier than falling asleep."
>
>
>
The fact that Sirius knew how dying felt proves that he had done it before. Although he would probably say this also if it were what Harry wanted. And so we move to the next one...
**3.What Lupin says right after that.**
>
> "And he will want it to be quick. He wants it over," said Lupin.
>
>
>
This is definitely not what Harry wants to hear--that his death is coming up quickly, and there's nothing he can do to stop it.
**4.The Appearance of Sirius and Lupin**
>
> Sirius was tall and handsome, and younger by far than Harry had seen him in life. He loped with an easy grace, his hands in his pockets and a grin on his face.
>
>
> Lupin was younger too, and much less shabby, and his hair was thicker and darker. He looked happy to be back in this familiar place, scene of so many adolescent wanderings.
>
>
>
The fact that Lupin and Sirius looked so much younger than Harry had ever seen them, combined with their few helpful lines, is proof that Harry did not dream them up, they were truly brought back with the Resurrection Stone. | The shades are real
-------------------
The shades called up by the Resurrection Stone do not converse much with Harry. There is little that they say that the Stone could not simply be drawing from his own memories of them. There is one thing, however:
>
> “You’ll stay with me?”
>
>
> “Until the very end,” said James
>
>
> “They won’t be able to see you?” asked Harry.
>
>
> “We are part of you,” said Sirius. “Invisible to anyone else.”
>
>
> —*Harry Potter and the Deathly Hallows*
>
>
>
And lo and behold, later:
>
> Two figures emerged from behind a nearby tree; Their wands flared and
> Harry saw Yaxley and Dolohov peering into the darkness, directly at
> the place Harry, his mother and father and Sirius and Lupin stood.
> **Apparently they could not see anything.**
>
>
> —*Harry Potter and the Deathly Hallows*
>
>
>
The shade of Sirius gave Harry *accurate* (and counterintuitive) information about the functioning of the Stone that he simply had not known before: that the shades were invisible to everyone else. That strongly suggests that the shade had access to information that Harry did not, which in turn suggests that he is in fact literally the spirit of Sirius.
---
For an additional piece of evidence, we can consult *Goblet of Fire*.
Harry experienced something quite similar in that book. When Harry's wand and Voldemort's connected, they experienced *Priori Incantatem*, and echoes of those Voldemort had killed came from the wand. When James Potter emerged, he gave Harry some advice:
>
> And he came...first his head, then his body...tall and
> untidy-haired like Harry, the smoky, shadowy form of James Potter
> blossomed from the end of Voldemort’s wand, fell to the ground, and
> straightened like his wife. He walked close to Harry, looking down at
> him, and he spoke in the same distant, echoing voice as the others,
> but quietly, so that Voldemort, his face now livid with fear as his
> victims prowled around him, could not hear....
>
>
> “When the connection is broken, we will linger for only moments...
> but we will give you time...you must get to the Portkey, it will
> return you to Hogwarts...do you understand, Harry?”
>
>
> —*Harry Potter and the Goblet of Fire*
>
>
>
Clearly this shade was an entity independent of Harry's consciousness, since it told Harry two things he did not know:
1. The Portkey would take him back to Hogwarts. Nowhere in the instructions given to Harry before the third task did it say this.
2. When the connection was broken, they would linger only a few moments. This was true, as demonstrated soon thereafter. Harry, of course, had no idea how *Priori Incantatem* worked.
**This is from an entirely different situation. Why is it relevant?**
This shows that a well-known effect can produce shades of the dead with independent knowledge and consciousness. Like the Resurrection Stone, of course, it does not truly bring the dead back to life, but it brings forth an echo of their consciousness. In other words, it is obviously *possible* for an effect very like that of the Resurrection Stone to be reproduced. There's no good reason to suppose that the second Peverell brother was not able to "bottle" this effect and store it in the Resurrection Stone. |

The alpha legion are a great example of why the heresy had to happen. They understand that only through eternal conflict can the human race survive and thus balance out the war.

] | Although the UML spec lets quite a lot of freedom as to what may appear in any UML diagram, the following should go into a UC diagram:
* Actors
* Use Cases
* possible a boundary that symbolizes the system under consideration (SUC).
This for the "main" UC diagrams, but you will likely create others that include requirements and/or classes of the design, etc.
Now, the actors are all objects that interact with the SUC in first place. Use cases are all those bubbles that signify some individual added value (not some technical procedure!!) the SUC offers to its actors.
Use case diagrams are about added value of the system, not about technical features! | The short answer, of course, is whatever level of detail (rather than complexity) is necessary. For the more thoughtful, use cases are most often used by the analyst to demonstrate to the non-technical stakeholders that all of their use-based requirements are being met. To that end, there should be enough detail so that managers, customers, and marketing have confidence that the developers will develop the product they want. For use case diagrams that capture decisions for developers, there should be enough detail that deeper design or programming can continue. It is best not to develop diagrams that try to address the needs of both types of users (stakeholders and developers). Finally, this is an iterative process of drawing and review. Start simple and add detail as necessary. |

Now, the actors are all objects that interact with the SUC in first place. Use cases are all those bubbles that signify some individual added value (not some technical procedure!!) the SUC offers to its actors.
Use case diagrams are about added value of the system, not about technical features! | **Use cases**
UML defines use cases:
>
> Use Cases are a means to capture the requirements of systems, i.e.,
> what systems are supposed to do. (...) A Use Case is a specification
> of behavior. An instance of a Use Case refers to an occurrence of the
> emergent behavior (...). Such
> instances are often described by Interactions.
>
>
>
In other words, it's an external view of what the system shall do in interactions with the external world.
The level of detail SHOULD be rather high. Typically, the top level of an interaction of a user with the system, that is the main function that a user would invoke for achieving his **goal**. Using the usual ATM example, the main goals would be "withdraw cash", "consult account balance", and certainly not "insert card", type in pin", "choose action in menu", "take money".
But there is no norm: you MAY as well have very detailed diagrams. It's just that they would be painful to draw, and not necessarily add to the understanding of the requirements. This is why, a recognized practice is to detail the high level use cases ("*sea level*") further as narratives, for example using [Cockburn's](http://alistair.cockburn.us/Use+case+fundamentals) approach.
**Cut off with sequence diagrams**
UML defines the sequence diagrams:
>
> A sequence diagram describes an Interaction by focusing on the
> sequence of Messages that are exchanged (..) Interactions that are
> described by Sequence Diagrams form a basis for understanding the
> semantics of the meta classes in the Interactions package.
>
>
>
Here the focus is more on the internals of the system, and messages exchanged. However, UML sees a use case as a specialized class diagram. With this in mind, if you would have very detailed use case diagrams, the sequence diagram should describe an interaction between and actor and a use case. |

1,164,982 | I have a tablet that run Windows 8.1 RT. I did a restore few days ago then I started do the updates availables in Windows Update. After a few Update/Reboot cycles, KB 2919355 April 2014 Update 1 was installed and now Windows Update keep searching for update forever. I've tried everything I found on the net to fix this (Windows Update Troubleshooter, stop the service / delete c:\Windows\SoftwareDistribution folder, etc.) but I can get this fixed.
I found two similar posts for Windows 8.1 with accepted answer that suggest to install KB3102812:
1. [Cannot install any updates on clean Windows 8.1](https://superuser.com/questions/1120602/cannot-install-any-updates-on-clean-windows-8-1)

However, the tablet run Windows RT and KB3102812 page (<https://support.microsoft.com/en-us/kb/3102812>) state that :
>
> The update for Windows RT 8.1 can be got only from Windows Update.
>

>
The update is also not available on the Windows Update Catalog for ARM architecture.
Does anyone has a suggestion to fix this Windows Update issue or any hint where I could go to download the KB3102812 for RT?

WSUSSCAN.cab
and then the installation hangs at "Searching for updates on this computer". I do not understand the linked article how to avoid that.
I found some advice, how to install an update cab files so I restarted the tablet, then I launched Command Promt as an administrator and used the follovig command:
dism /online /add-package /packagepath:"C:\foldername\Windows8.1-KB3138615-arm.cab"
It seems the update KB3138615 is installed.
Then I had to restart the tablet, run the Windows update troubleshooting tool and after another restart the Windows Update service started to work.
So it is OK now, but I am not sure about my installation method of the kb3138615. There is also the WSUSSCAN.cab in the folder and I didn't install it. Is it OK?

] | It depends on the type of plane and even on the company. These could be seats in first or business class rather than economy class. You can only choose these seats if you have paid for them ... On the other these could be seats next to an emergency exit. You usually have some extra room for your legs there. On the other hand, you cannot store your hand-luggage under the seat. The trays are in the armrest. On some planes this means that the seats have a reduced width. Moreover, in case of trouble, you are expected to handle the emergency exit. This also means that you need to be physically able to do this. I have once been refused such a seat, because I had a splint on my foot due to an accident.
I suggest you have a look at [SeatGuru](http://www.seatguru.com/). There you will find seating plans and comments on the good and bad seats. | According this scheme:
There are emergency exits near row 8-9.
I think that's why there are some restrictions on this. But I don't think this is bad place.
On this scheme green is for good place, yellow is for not very good place, and red is for the bad place. |

] | What's explained in Myst
------------------------
**Who are you?**
This is never explained in-game. I believe the intent is that the player character is you.
**How did you get there?**
You found a book, which the narrator (late in the game revealed to be Atrus) had intended to destroy, or at least get rid of. This book took you to the island of Myst, but with no route home. Touching one of these books is a one-way trip to another realm, a picture of which is on the page you touch to start the game.
This one-way trip mechanic is also how Sirrus and Achenar became trapped in their red and blue books. The island also has books that take you to other areas, where you can solve puzzles, but they each have a book that will take you back to Myst, the hub of this adventure.
What's explained outside of the first game
------------------------------------------
**Who are you?**
You are "[The Stranger](http://en.mystlore.com/wiki/The_stranger)," a 19th century everyman who finds the Myst linking book. There's actually not a lot of backstory on the protagonist, period. There's some referenced material at the bottom of the linked wiki page for the Stranger, such as:
>
> According to a Myst Guidebook, the Stranger found the Myst book in a San Francisco library. He read the book, which described perfectly an island, and saw the linking panel in the final page. This information can't be canon[.]
>
>
>
As it's indicated in parts of the lore that the game series takes place in the 19th century, so it's not really possible for the Stranger to be you (unless you're really, really old...).
In subsequent games, Atrus (and other characters) will speak to you as if you're the same person as the protagonist of Myst, so for the main game series it's assumed these adventures are had by the same person.
**How did you get there?**
To understand this, you'll need to understand a bit more of the lore. A lot of this is in Riven, (Myst's sequel) if you know where to look. However, Riven is also light on story for the most part. It wouldn't surprise me if you completed that game and were still confused.
I'll try to keep this as spoiler free as I can, but you should know that **there may be spoilers here.**
The worlds ("Ages") in the Myst series are "[descriptive books](http://en.mystlore.com/wiki/Descriptive_book)" written by [D'ni](http://en.mystlore.com/wiki/D%27ni_(race)) trained in the [Art](http://en.mystlore.com/wiki/Art). In addition to descriptive books, the D'ni also were capable of creating "[linking books](http://en.mystlore.com/wiki/Linking_books)" where touching the page would take you into the Age the book was linked to.
For the most part, humans and the D'ni did not interact, until the events leading up to the Myst series. By the time the series starts, the D'ni are mostly creatures of legend, and the books they authored are quite rare.
Owing to a conflict between Atrus and his father, Atrus fled to the age of Myst along with his family. He was afraid that if he left his Myst linking book behind, he'd be followed. Thus, he held the book over what he believed to be an infinite void called the Star Fissure. When he linked to Myst, the linking book he used fell into the fissure, putting it out of reach of those who would follow him and do him harm.
However, a couple of things happened he wasn't expecting. One was that his children eventually became tyrannical (somewhat because of his neglect), and they conspired to trap him and his wife.
Luckily, the other was that the Myst linking book was not destroyed. It is found by The Stranger, who arrives and (eventually) helps him resolve many of these conflicts. | This information is explained in the games instruction manual, but can be found at [other sources as well](http://en.wikipedia.org/wiki/Myst#Plot):

This is intentional, as it allows the player to experience the world as themselves, rather than forcing the player to take on an unfamiliar and therefore less immersive role (such as a [space marine](http://en.wikipedia.org/wiki/Doom_%28video_game%29), [theoretical physicist](http://en.wikipedia.org/wiki/Half-Life_%28video_game%29), or [black Scottish cyclops](http://www.youtube.com/watch?v=rNM4eFsX68Y)). | What's explained in Myst
------------------------
**Who are you?**
This is never explained in-game. I believe the intent is that the player character is you.
**How did you get there?**
You found a book, which the narrator (late in the game revealed to be Atrus) had intended to destroy, or at least get rid of. This book took you to the island of Myst, but with no route home. Touching one of these books is a one-way trip to another realm, a picture of which is on the page you touch to start the game.
This one-way trip mechanic is also how Sirrus and Achenar became trapped in their red and blue books. The island also has books that take you to other areas, where you can solve puzzles, but they each have a book that will take you back to Myst, the hub of this adventure.
What's explained outside of the first game
------------------------------------------
**Who are you?**
You are "[The Stranger](http://en.mystlore.com/wiki/The_stranger)," a 19th century everyman who finds the Myst linking book. There's actually not a lot of backstory on the protagonist, period. There's some referenced material at the bottom of the linked wiki page for the Stranger, such as:
>
> According to a Myst Guidebook, the Stranger found the Myst book in a San Francisco library. He read the book, which described perfectly an island, and saw the linking panel in the final page. This information can't be canon[.]
>
>
>
As it's indicated in parts of the lore that the game series takes place in the 19th century, so it's not really possible for the Stranger to be you (unless you're really, really old...).
In subsequent games, Atrus (and other characters) will speak to you as if you're the same person as the protagonist of Myst, so for the main game series it's assumed these adventures are had by the same person.
**How did you get there?**
To understand this, you'll need to understand a bit more of the lore. A lot of this is in Riven, (Myst's sequel) if you know where to look. However, Riven is also light on story for the most part. It wouldn't surprise me if you completed that game and were still confused.
I'll try to keep this as spoiler free as I can, but you should know that **there may be spoilers here.**
The worlds ("Ages") in the Myst series are "[descriptive books](http://en.mystlore.com/wiki/Descriptive_book)" written by [D'ni](http://en.mystlore.com/wiki/D%27ni_(race)) trained in the [Art](http://en.mystlore.com/wiki/Art). In addition to descriptive books, the D'ni also were capable of creating "[linking books](http://en.mystlore.com/wiki/Linking_books)" where touching the page would take you into the Age the book was linked to.
For the most part, humans and the D'ni did not interact, until the events leading up to the Myst series. By the time the series starts, the D'ni are mostly creatures of legend, and the books they authored are quite rare.
Owing to a conflict between Atrus and his father, Atrus fled to the age of Myst along with his family. He was afraid that if he left his Myst linking book behind, he'd be followed. Thus, he held the book over what he believed to be an infinite void called the Star Fissure. When he linked to Myst, the linking book he used fell into the fissure, putting it out of reach of those who would follow him and do him harm.
However, a couple of things happened he wasn't expecting. One was that his children eventually became tyrannical (somewhat because of his neglect), and they conspired to trap him and his wife.
Luckily, the other was that the Myst linking book was not destroyed. It is found by The Stranger, who arrives and (eventually) helps him resolve many of these conflicts. |

At any rate, flash seems to be completely deactivated, and I don't see a place to re-enable it anywhere in the preferences. I've done a bit of googling on the issue, but only found information about how to disable flash, not how to actually enable it.
I have the flash 10 debug player installed, and it works fine with Chrome and Firefox. What could be the matter? | 2009/07/16 | [
