What should we do when the website concept conflicts with the functionality?  Recently am participating actively on  and as the website is new and in beta, the questions are less, traffic is less, inorder to contribute helpful questions, I tend to use "Answer your own Question" functionality to provide decent recommendations if am using those software on my personal computer, or on my cell phone.  But this conflicts with the website concept. I got a comment on my answer which says        And I've no way to prove that am not, so what to do in these conditions? I already raised a question on respective meta, but I wanted to know what should we do when the SE functionality conflicts with the website concept?   Should users stop answering their own question? If yes than should we revoke the functionality for a particular website? If no than what should I do so that users don't think that am affiliated with the developers?   I have a decent reputation on Stackoverflow and I know what does the community expect. Whenever I contribute some screenshot, or some piece of explanation, I tend to write a Credit note below each answer, so am not that cheap to confess that yes, the developer paid me to post an answer but that's not the case here.  This will lead to grudges amongst users.
I asked a  recently, looking for examples of an online tool. Per the , I answered my own question with a few examples that I had already found. I did this so that these examples would be included in the answers, along with the rest.  The question has received only down votes and insults saying that this shouldn't be done.   Should I not answer my own questions?
I need to compile between two and four times before I see changes I make in the editor (TeXstudio) and each time I compile, a new .tex file is created with random letters and numbers at the end.   For example, If I create the file hello.tex and compile two to four times I'll get the file,   hello.tex.QU6664      then I make some small changes in the editor and compile two to four times I'll get the additional file,   hello.tex.Ak6664   After continuing to do this (each time compiling between two to four times before I see the changes I made), I now have many files that look like  hello.tex.QU6664, hello.tex.Ak6664, hello.tex.YX6664, hello.tex.sN6664, hello.tex.Ss6664, ...   A little bit of additional information (in case it's relevant): Everything was working fine up until a few days ago, i.e. only needed to compile once and only the file hello.tex was created. I still only get one .aux,  .synctex and .pdf files. I use TeXstudio to write and compile. I don't think it has anything to do with the bibliography (I tried removing bibliography altogether and still having the same problem).  How do I prevent these additional files from appearing and only compiling once like I used to? Has anyone had a similar problem? What is the rigor behind U subsitution? $ \int f(g(x)) dx = \int \frac {f(u)}{u'} du$  requires that  $ \int f(x) dx = \int f(x) \cdot dx$  but dx just represents the variable that F(x) +c is a function of. So why is it legal for dx to be treated algebriacally?  I tried investigating this property by using riemann summation:  $\lim\limits_{n \to \infty}(\sum_{k=1}^n f(\frac{kx}{n} )\frac{x}{n}) = \int_0^x f(t)dt= (F(x)+c)-(F(0)+c)$  and so you can define   $ \lim\limits_{n \to \infty} (\sum_{k=1}^n f(\frac{kx}{n} )\frac{x}{n})+F(0)+c)  = \int f(x) dx$  you can write $\frac{x}{n} = dx$ and $k\frac{x}{n}=kdx= x_k$  then you have  $ \lim\limits_{n \to \infty} (\sum_{k=1}^n f(x_k)dx)+F(0)+c) = \int f(x) dx$  since  dx is being written to be multiplied by the series, then you can define dx in different terms to aquire an integral in terms of other variables.   but that exists only in abstraction. I can't quite sufficiently complete the task of doing so. How to merge columns in a table? I have this table, but wanted to format the first row. I like to match the two columns of first row, and last two columns of the same first row. Any suggestion on how to do that?  \begin{table}[!h]  \caption{Comparison of percentages.} \begin{tabular}{lclclclclc} \hline \hline  Mode &amp;  Var  &amp;  Cum\\ \hline {}       &amp; EF   &amp; CHF    &amp; EF2   &amp; CHF2\\ 1   &amp;  17.5 &amp; 19.1   &amp; 17.5  &amp; 19.1\\ 2   &amp;  11.8 &amp; 12.7   &amp; 29.3  &amp;  31.9\\ 3   &amp;  6.6  &amp;  5.6         &amp; 35.9    &amp;  37.4\\ \hline \end{tabular} \end{table} formatting long numbers as strings in python What is an easy way in Python to format integers into strings representing thousands with K, and millions with M, and leaving just couple digits after comma?  I'd like to show 7436313 as 7.44M, and 2345 as 2,34K.  Is there some % string formatting operator available for that? Or that could be done only by actually dividing by 1000 in a loop and constructing result string step by step? "Have you ever seen anyone walk (walking) the streets like that?"

I saw him kiss her the other day. I saw him kissing her the other day.  Are both the above sentences grammatically correct? Do they mean the same? And I'm sorry, if the latter two sentences come off immature .-. I couldn't come up with better sentences. "No such file or directory" when trying to remove a file, but the file exists? I am trying to remove a png image that was uploaded to my server via a PHP script. Whenever I try to delete it both through ftp and terminal, I get the error   No such file or directory   However, when I ls in the dir, the file is listed and it is also listed in my ftp client. I have tried creating a file with the same name and I end up getting two files with the same name.   I can open the file that supposedly does not exist, but I still can't remove it. I have also tried rebooting my server. Any ideas what may be the issue? I am running a 64 bit version of Ubuntu, but I don't think its a 32/64 bit issue. I should also note I have removed many other png files uploaded by the same PHP script.

I know how to use PDFs to calculate probabilities, but I don't think I understand them. For example, at $X=0$ the PDF of the standard normal distribution is $\approx 0.4$. Does this have any useful meaning? Here's :        At the moment, the latest entry there is October 13, which would be mistaken to mean October last year (2012), but it actually is October 2010. This applies to all the filters in the activity tab. How to place text above the figure/table How to place text above the rotated Figure (LANDSCAPE) in the same page. I tried but text automatically moved to the following page.  TEXT TEXT....   \begin{landscape} \begin{table}[] \centering \includegraphics[width=160mm]{figures2/comparation3.png} \caption{A comparison of Aloha protocols} \label{tab:ComparationAloha} \end{table} \end{landscape}     I added this code, but one part of table disappeared. I must have type TABLE since I need it for list of tables later.  \lipsum[11] \begin{table}[h!] \rotatebox{90}{\parbox{100mm}{ \includegraphics[width=160mm, rotate=90]{figures2/comparation3.png} \caption{A comparison of Aloha protocols} \label{tab:ComparationAloha}}} \end{table} \lipsum[12] My Ubuntu 12.04 was normally updated through the Update Manager, something about gtk.

Does Dragon Age Inquisition make use of save data from previous games in the series?  If so, what benefits does this provide? Can I configure Ubuntu to never install a specific package even if it is required by another package I install? US Customs when coming through Canada I have an upcoming trip where I will be flying to and from Copenhagen, through Toronto.  I notice that my departure and return gate in the Philadelphia airport is not in the international terminal.  Where will I clear customs? In Iron Man 3, we saw that Tony was able to control Mark 42 armor remotely.  Talking about the Hulkbuster armor used in Avengers: Age of Ultron, it was very dangerous because Hulk's unpredictable rage could rip it apart any time.  Why didn't Iron Man simply control the Hulkbuster armor remotely? Adding curved features to map with ArcGIS API for JavaScript? I've tried without much success to add a curved line feature to the ArcGIS JavaScript map.    I created a polygon with a curved edge in ArcMap:   However, when I load this same feature in the web API, it becomes segmented:   The problem started when I tried to create a curved feature from the JavaScript API itself, which only seems to allow full circle features (not circular arcs).  This makes me think that curves are still unsupported in the JavaScript API. Do you know any way around this? Do you have any other ideas on alternatives I can use to create and correctly view curved features? Can Yoda pilot a starfighter? In a trailer for Kinect Star Wars, I saw Yoda driving a Jungle Speeder and that got me wondering. Can and has Yoda ever piloted a starfighter?  During the Clone Wars, it seems plausible that they could commission a small-sized green Jedi starfighter. Is their any indication that he has piloting experience? How can I produce the text Word_one_two in LaTeX?  I tried:  Samp\_Dist\_Corr   But, it doesn't quite look right. Also, I want it in the typewriter font, so actually, I'm doing:  \texttt{Samp\_Dist\_Corr}   I find it looks a bit like the underscore is merging in to the bottom of the "D", but maybe it's just because of the typewriter D? I let my younger cousins play on my S4 from time to time, but now I have found that all the words they have used are the first to come up when I use my phone to text. It has gotten quite irritating. Samsung seems to have very hard to find settings compared to my old Sony Ericsson so I cannot find where to get rid of the word history typed onto my phone's keyboard.
