I am new to LaTeX and I managed to add references to a document with natbib however when I preview it, the reference colour in the brackets appears to be in green colour. Everything else is fine. Would it still be green when I print it out? Or is this just a convenient built-in feature? How can I make it into black either way if I find this annoying? I am attaching a picture to show u what I mean.

How does Ubuntu partition the disk when we choose "Erase disk and install Ubuntu" during installation? Datasets constructed for a purpose similar to that of Anscombe's quartet I've just come across  (four datasets that have almost indistinguishable descriptive statistics but look very different when plotted) and I am curious if there are other more or less well-known datasets that have been created to demonstrate the importance of certain aspects of statistical analyses. Weird artifacts in my UV mapped texture Any ideas what's causing those chunks of geometric artifacts?  Argh. Unresolved external symbol on static class members I installed kubuntu-desktop just to experiment with its interface.  Then I decided to remove and did the traditional apt-get purge and autoremove but it seems elements of kubuntu are still there. For example interface elements, scrollbars, bootscreen etc are still there.  Is there any method I can completely remove without installing a fresh copy of ubuntu?

Allow Documentation in other Stack Exchange communities I'm a Salesforce developer and would love Documentation to be available in other Stack Exchange communities. The reason is  a lot of Salesforce developers get help, especially newer ones like myself. The developer forums and documentation on  is mediocre. It would be nice to allow users to create their own and give pack on Nginx: Forward all Subdomains My code doesn't work with second level tld's like domain.co.uk Here is my conf:   # add www.   if ($host ~ ^(?!www)) {    rewrite ^/(.*)$ http://www.$host/$1 permanent;   }    # remove subdomain   if ($host ~ &quot;^www\.(.*)\.(.*\.([a-z]{2,4}|[a-z]{2}\.[a-z]{2}))&quot;) {    set $host_without_sub $2;    rewrite ^/(.*)$ http://www.$host_without_sub/$1 permanent;   } How to split by commas that are not within parentheses? C# loop - break vs. continue In a C# (feel free to answer for other languages) loop, what's the difference between break and continue as a means to leave the structure of the loop, and go to the next iteration?  Example:  foreach (DataRow row in myTable.Rows) {     if (someConditionEvalsToTrue)     {         break; //what's the difference between this and continue ?         //continue;     } } How to determine when Settings change on iOS sudo: /etc/sudoers is owned by uid 501, should be 0 To run programs as sudo without password, I edited /etc/sudoers with wrong content.   Then I re-edited it with Mac's default text editor(course sudo cannot be used when /etc/sudoers is wrong).

I have a seasoned cast iron skillet, and I don't want to mess up the seasoning when I'm cleaning it.  What do I use and what don't I use to get it back to clean?  I've heard not to use soap and to make sure it is dry, but nothing beyond that. If a>0 and b>0,  $ \lim_{x\rightarrow +\infty } \sqrt[x]{a^x+b^x} = ? $  What I was trying to do: Suppose a>b. Then, for sufficiently large values of x, $ a^x &gt;&gt; b^x $; so $\sqrt[x]{a^x+b^x} \rightarrow \sqrt[x]{a^x} \rightarrow a $ when $x \rightarrow +\infty$.   Is that idea correct? How can I formalize it? Why is the amount of photos that fit on one card dependent on ISO? Can I use my single entry Schengen visa to go to a different Schengen country than originally planned? My friends and I planned to visit Germany, so I got a single entry tourist Schengen visa to Germany. However, my travel plans have changed since then, because my friends are going to Italy instead.
