What causes the 'Connection Refused' message?
Positive operator has a positive spectrum? I am trying cmd --> MMC --> Server Manager and then connecting to my Server 2012 no GUI  but i keep getting the following error The WinRM client cannot process the request  I am unable to upload images right now  This is not related to other post "How to Remote Manage Windows Server 2012 in Server Manager?" because title and description of that post is quite different from what i am asking I'm having issues with my macbook pro OS X 10.7.5.  It used to connect to the wifi router (D-Link N300, DIR=615) no problems.  But for the past several weeks, I haven't been able to at all.  What pops up when I select my wifi network from the list:   "Failed to join "network" A connection timeout occured".   What happens when I try to enter my password manually:   "Connection timeout"   What I've tried to do as solutions:   Google Restart router by pressing reset &amp; refresh button Delete System &amp; User (Login) Keychain access Network > Gear symbol by the + and - bottom left of the screen > Set Service Order > Drag Wifi to the top If a thin metal plate is placed between two charges $+q$ and $+q$, will this cause a change in the electrostatic force acting on one charge due to another? What is the concept behind this? What will happen if the metal plate is thick? The table cards were A,K,K,8,3. All four suits were on the board. Player one had A,8. Player two had A,3.

Can houseplants actually improve air quality? I have an independent variable called "quality"; this variable has 3 modalities of response (bad quality; medium quality; high quality). I want to introduce this independent variable into my multiple linear regression. When I have a binary independent variable (dummy variable, I can code 0 / 1) it is easy to introduce it into a multiple linear regression model.  But with 3 modalities of response, I have tried to code this variable like this :  Bad quality      Medium quality      High quality       0                1                  0      1                0                  0      0                0                  1      0                1                  0   But there is a problem when I try to do my multiple linear regression: the modality Medium quality gives me NA:    Coefficients: (1 not defined because of singularities)    How can I code this variable "quality" with 3 modalities? Do I have to create a variable as a factor (factor in R) but then can I introduce this factor in a multiple linear regression? I've recently flagged the following , which I got in the flag queue.   The answer does not seem to attempt to address the question at all. It looks like a comment on one of the other answers (probably Luca's).  It got rejected with the following reason:  declined - flags should not be used to indicate technical inaccuracies,            or an altogether wrong answer   I did not flag this because I thought it was wrong, I flagged it because I didn't think it was an attempt to answer the question. For what it's worth, I don't get what the guy who provided that answer even tried to say.  Was I wrong to flag it? If so why? Why does the "Unanswered Questions" tab show questions that have answers? How to handle a deliberate duplicate question What's the difference between cards, panels, and tiles? It seems as if with some of the modern front-end development frameworks there is a blur between the different types of 'container' elements. Whether this is an attempt to abstract the design from implementation or if this is due to there not being any standardization of terminologies I am not sure, but it leads to the fact that in some design frameworks I see the term panels being used but not cards (e.g. Bootstrap 3) while in others the term cards exists but not panels (e.g. Iconic), and perhaps both exist in others?  From a design perspective, it seems that both cards and panels are just containers, and since there's nothing that defines how big a card can get and how small a panel can be, I am wondering whether there's really any difference. From an implementation perspective, it seems that cards should be used for smaller size design elements and are preferred on mobile specific applications, whereas panels are used for a wider range of design elements and are preferred on desktop specific applications.  Is there any evidence/reference/examples that will help to illustrate or highlight the (lack of) differences? For some reason I think cards and tiles are more closely related to each other, and that panels seem to be in a slightly different class/family?  If we take the argument that there are no differences, then it is hard to understand why people associate 'tiles' with Microsoft 'Metro' style home pages, while on Google and Android apps it is 'cards' and for Java and Gnome applications it is 'panels'. Perhaps there are some contextual or implementation differences?  UPDATE: with the release of Bootstrap 4, it seems like cards are basically equivalent to panels (since one component has replaced the other), but with this comes the cost of having to maintain a more flexible container that will make it difficult to implement consistently. According to Bootstrap:      A flexible and extensible content container. It includes options for   headers and footers, a wide variety of content, contextual background   colors, and powerful display options.   FURTHER UPDATE: It seems as if Bootstrap 5 and Material.io have adopted the card UI component in the new world of responsive and mobile first/multi-device ecosystem design systems while "tiles" have a very specific meaning in the Microsoft Fluent Design System:      A tile is an app's representation on the Start menu. Every app has a tile. When you create a new Universal Windows Platform (UWP) app project in Microsoft Visual Studio, it includes a default tile that displays your app's name and logo   Panels don't seem to be part of the vocabulary anymore, as least in terms of a UI component, but in the Microsoft and Java world it still represents an abstract concept of organisation layouts of UI components.

I am a final year PhD in UK in a scientific discipline and I am writing my thesis. I have already published 2 journal papers and I have submitted 2 more papers for publications. My department does not allow a "publications-based" thesis so I need to write a thesis in the context of a book etc.   As I write my thesis in a couple of places, especially in the literature review, I tend to reuse sentences from my publications. I try to restate them a bit, maybe change some words for their synonyms etc. but it is practically me writing about what I wrote before. It goes without saying that I cite/quote me at the end of a passage if I say something non-obvious (I found that slightly funny. :) ). The problem is that occasionally I am just explaining for instance how a certain estimation technique works; in that case I cite the original authors and not myself. The syntax in those occasions though is practically the same as the original passage I used in my publication; as I have explained it once and was consider good, I find no reason to reinvent myself (I do a mild rewording as I mentioned but that is quite insignificant). Same things goes for listings. I do cite my paper in the beginning of a big list as the list's source but the list itself is almost identical as the one in "my" paper; in those cases I don't use quotations, just attribution "[]".  Is there an obvious guideline? The basic definition of plagiarism "reproducing the work of another person's as your own" is not (directly) applicable to me because I am the other person (almost *); if I am using other people's work I do cite them but I don't cite myself, citing them, in quotation marks!  I am a bit "fuzzy" about how not to plagiarize myself in my thesis (I have had no problem regarding my journal publications).  (* In all publications mentioned I am the first -but not sole- author.)
