How do I install applications in Ubuntu?
Currently, the only way to ask for something to be migrated to a site that isn't part of the standard migration path is through a custom mod note.  I currently have two active custom mod notes on Stack Overflow that ask for migration that are not standard targets for SO.  I believe the questions could be better answered on another site.  Fortunately, or unfortunately, the questions have been answered, and answers have been up voted and accepted. At this point, a week and a half later, migrating either of the questions would be disruptive to both communities and not necessarily produce a better answer (they've got accepted answers).  The unfortunate part is I really do believe that both questions could have gotten better answers and more attention on another site.  What I would like to see is a more streamlined way to flag for moderator attention for migrations.  The UI would look something like this:    This would allow people to find the proper site easily.  No more "Migrate this to Mathamatica.SE" because, well, that doesn't exist.  Something that I didn't do on this mock up is add a link to the corresponding help/on-topic page for the target site.  Something people could check and click before hitting the submit button.  I don't have this quite right again, because while that shows a "closing for off topic", this is a flag and not a vote to close.    The "flag for migration" is only one part of this though.  The other part would be to make another flag queue style thingy for moderators in which they could look at just migration flags created through the above interface.  By providing the mods with a "just migration" view into the flags, questions that should be migrated can be quickly identified from the multitude of existing flags and handled promptly before the migration would be disruptive. I have a simple one line command which works perfectly in terminal, but does not work in the "Startup Applications" app thing.  The line of code is : xmodmap /home/seph/Code/Ubuntu\ Scripts/Xmodmap  It's not that much of a hassle to copy it from "Startup Applications" and paste it into terminal, but I don't really get why it isn't working.  I followed someone else's instructions to do it in the first place, so maybe I did something wrong?  In any case, wouldn't it be the obvious and logical assumption that it just types whatever you put in it into Terminal? Does English allow a zero copula in subordinate clauses? In a casual search of the web, I found a few indications English does not allow zero copulas ().  However, I frequently see sentences with subordinate clauses that juxtapose a noun phrase with an adverb phrase, such as the following from a contemporary sci-fi author:  Kai stares up at me from the grave, his eyes hard as obsidian.  If this clause were made into a sentence, it would take an obligatory verb:  *His eyes hard as obsidian.  His eyes are hard as obsidian.  The original clause seems to contain an implicit "to be."  Is it an example of a zero copula?  If not, what is this construction called? Baffling Elevation Profile out of Profile Tool Plugin When using the Profile Tool plugin I get a graph that looks like the 2nd derivative of what I want. That is, it looks like the rate of change of the slope of the elevation profile. I just want the elevation profile! The data is present for good 1' contour lines. Why is the Profile Tool interpreting the data in such a bizarre way? What am I missing? And what are the Min and Max units? I've tried to find any solution or proof for $$\langle x| x' \rangle=\delta(x-x'),$$ but I only came to this post:   So I got the information, that the vector $|x\rangle$ form a dirac-normalized basis for the Hilbert Space.   I know that the dirac-delta distribution is defined like this: $$\delta(x-x') = \begin{cases} 0 &amp;\mbox{if } x\neq x' \\ \infty &amp; \mbox{if } x=x' \end{cases},$$ this means that my x' is a point on my x axis where I have my infinite high peak. And also $$\int_{-\infty}^{\infty}dx\cdot \delta(x-x')=1.$$  But how actually correlate this with the scalar product of vectors x, x' in the Hilbert Space that form a so-called 'diracl-normailzed" basis of it?  Can you give me some tips on this please? Or maybe you actually know a link, where this is explained. What is serial voting and how does it affect me? I just noticed that I lost a bunch of points from my reputation score, and I used the "reputation" tab on my user profile page to try and track down the cause.  During my investigation, I noticed there was an unusual event of type "reversal". In the normal place of a question title, it says "voting corrected".     What does this mean, and what caused it?  Did I do something wrong? Why did I lose all of that reputation? Is the system punishing me for leaving too many good answers?  Is there any way to earn it back? I'm looking for a free RAW editor/converter on Windows. Can you tell me some strong/weak points of them comparing with Capture NX and/or Adobe Photoshop Elements?       - conversion &amp; EXIF  - white balance  - registration not possible anymore   EXIF editing would be a nice bonus.  Related: $$\lim_{n\to\infty} (1+\frac{2}{n})^{n^2} e^{-2n} = ? $$         $e$   $e^2$   $e^{-1}$   $e^{-2}$      My answer is 1. Since $$\lim_{n \to \infty} \left(1+\frac{2}{n}\right)^{n} =e^{+2}.$$  Therefore $$\lim_{n\to\infty} \left(1+\frac{2}{n}\right)^{n^2} =e^{2n}.$$  Where am I wrong? How to open a web page from my application? I want to make my WPF application open the default browser and go to a certain web page.  How do I do that? I have a Win 7/11.10 dual boot system with Grub 2 as the default bootloader. However, I want to make Windows bootloader the default bootloader (grub 'dos' like interface scrares the hell out of my sister) so when I start the PC I will have the following boot options: 1. Windows 7 2. Ubuntu  NB: A process to reverse this operation so Grub can be the default bootloader again will also be appreciated How did Sauron remain in control of the Nazgûl? The One Ring gave Sauron control of the Nine, yet when it was taken from him he still possessed the power to control them (or, at least he regained it towards the end of the third age).  Why is this?   mentions that he drew the Nine to him, but not how. Can the expression $\sqrt{n} + \sqrt{m}$ be rational if neither $n,m \in \mathbb{N}$ are perfect squares? It doesn't seem likely, the only way that could happen is if for example $\sqrt{m} = a-\sqrt{n}, \ \ a \in \mathbb{Q}$, which I don't think is possible, but how to show it? Splitting lines with points while maintaining other dissolved lines? I am on ArcGIS Desktop 10.2. I have a line feature class of a stream network. I also have a point feature class along the main stream (line) where a catchment enters that stream. I have dissolved my whole streams layer into one line feature and want to split this feature at the points.    However, when I use the  tool, the lines that don't have a point splitting them are still being split at the intersection of two streams.    Why did this line not stay as one feature with the other lines on that side of the splitting node and how can I prevent this from happening? Convergence of $\sum_{n=1}^\infty (-1)^n(\sqrt{n+1}-\sqrt n)$ Please suggest some hint to test the convergence of the following series $$\sum_{n=1}^\infty (-1)^n(\sqrt{n+1}-\sqrt n)$$ Why does HTML require that multiple spaces show up as a single space in the browser? I have long recognized that any set of whitespace in an HTML file will only be displayed as a single space.  For instance, this:  &lt;p&gt;Hello.        Hello. Hello. Hello.                       Hello.&lt;/p&gt;   displays as:  Hello.        Hello. Hello. Hello.                       Hello.  This is perfectly fine, as if you need multiple spaces of pre-formatted text you can just use the &lt;pre&gt; tag.  But what is the reason?  More precisely, why is this in the specification for HTML? Astrophotography picture with too much noise. How do I correct this in postprocessing? This is the Milky Way above Kakadu National Park, Australia, and my first try at astrophotography.    Thirty second exposure, f/4.0 at 17mm with ISO 12800 (!!) which in hindsight probably was way too high and resulted in a lot of noise. I also used Picasa to increase contrast, but I probably went a bit overboard there as well.  , I am looking for input on how to better postprocess this picture to reduce noise. NewForm.aspx disappeared Why is the space between words in my source code listing so big? I used the following code to list my java code, but the it looks like there's too much space between words. What can I do?  % source code listing \usepackage{listings} \usepackage{color} \usepackage{xcolor}  \usepackage{caption}  % citation style \usepackage{apacite} \DeclareCaptionFont{white}{\color{white}} \DeclareCaptionFormat{listing}{\colorbox{gray}{\parbox{\textwidth}{#1#2#3}}}  \begin{document} \begin{lstlisting}[label=some-code,caption=bind to service call] bindService(new Intent(this, Recognizer.class), recConnection, Context.BIND_AUTO_CREATE); \end{lstlisting} \end{document}   The snapshot of what I got. The code not completely shown, and space too wide, in function bindService. How do I install Guest Additions in a VirtualBox VM? I've recently installed Ubuntu on Oracle's Virtualbox.  Now I want to install the guest additions.  I started up my Ubuntu guest OS, clicked "Devices" and chose "Install Guest Additions". Nothing happened, and I don't see the CD icon on my desktop.  How can I make this work? Where can I find some guidance on index strategies?
