Why does the reputation need to be publicly displayed? Possible Duplicate:          The idea of getting greater privileges with greater reputation is good, but what is the benefit of publicly displaying that reputation? Since SO claims to be about good questions and answers, that purpose is better served if the reputation is only visible to the account owner (and, of course, the site admins). This would better ensure that content gets pushed up solely by its merit, and not based on the author. (See )   Edit (copied from comment to an answer below): Once you have gathered high reputation, you can also gather more reputation with ordinary answers, especially from newbies (newbies on the topic, not on the site) who usually choose to accept or upvote an answer on the assumption that "since a high-rep user has posted it, it is probably right". Can you guarantee that doesn't happen often? Protect email addresses in the user description from bots I've noticed that emails are not protected in the user description. For example  entered his email and when viewing the source code of the page it is plain text that malicious bots could harvest and exploit to spam. It would be nice if email addresses were automatically encoded to prevent this. How do I install the ubuntu-restricted-extras package? An easy bash completion tutorial?

Tools for automating document compilation A lot of people write makefiles that say something like  paper.pdf: paper.tex         pdflatex paper         bibtex paper         pdflatex paper         pdflatex paper   To handle re-running TeX to get new/changed references and so forth.

It is just interesting, as in Google all other things pop up when I try to search for an answer! How to do a generalized linear model with multiple dependent variables in R? Figure or longtabu/longtable causes bottom margin overflow I have been searching for a while now without any luck, so I hope you can help me. The problem is that when I insert a figure/longtabu on my page, the text below is running out of the page, like this image shows:    Do you know what the problem is here?

Whilst going through 'A brief history of time', I faced difficulty in understanding the . How can an individual electron cause fringes on screen? I was unable to understand it? Please explain it simply. I've been wondering about this one for a while; I find it a little weird how abruptly it happens. Basically, why do we need just three uniforms for $Z_n$ to smooth out like it does? And why does the smoothing-out happen so relatively quickly?  $Z_2$:     $Z_3$:    (images shamelessly stolen from John D. Cook's blog: )  Why doesn't it take, say, four uniforms? Or five? Or...? Can anybody explain the UNABLE_TO_LOCK_ROW error? Are all multiplicative functions additive? Suppose $cf(x)=f(cx)$ and $f:\mathbb{R}\to\mathbb{R}$. I believe it follows that $f(x+y)=f(x)+f(y)$.   Proof: There is some $c$ such that $y=cx$. Then  $$f(x+y)=f\left((1+c)x\right)=(1+c)f(x)=f(x)+cf(x)=f(x)+f(cx)=f(x)+f(y)$$  QED.  I wonder if the same thing holds for when $f:\mathbb{R}^n\to\mathbb{R}^n$? I can't use the same trick, because all vectors are not scalar multiples.  I tried thinking of it in terms of basis units, but didn't get anywhere. What are the strengths and weaknesses of each follower? In my past experiences, I have almost never typeset my manuscripts according to the formats required by the journals to which I would like to submit. I leave my manuscripts as produced by the LaTeX article documentclass.  Recently I am wondering: Would such a behavior generally give handling editors a negative first impression? How can I start automatically a command on Ubuntu 18.04? The definition for marker below is from tcolorbox.doc.s_main.sty. With earlier versions of Texlive (and tcolorbox), this worked fine, but with updated Texlive, it does not.  \documentclass{article} \usepackage{xcolor,tikz,tcolorbox} \usetikzlibrary{shadows} \tcbuselibrary{skins,hooks} \makeatletter % from tcolorbox.doc.s_main.sty \newtcolorbox{marker}[1][]{enhanced,   before skip=2mm,after skip=3mm,   boxrule=0.4pt,left=5mm,right=2mm,top=1mm,bottom=1mm,   colback=yellow!50,   colframe=yellow!20!black,   sharp corners,rounded corners=southeast,arc is angular,arc=3mm,   underlay={%     \path[fill=tcbcol@back!80!black] ([yshift=3mm]interior.south east)--++(-0.4,-0.1)--++(0.1,-0.2);     \path[draw=tcbcol@frame,shorten &lt;=-0.05mm,shorten &gt;=-0.05mm] ([yshift=3mm]interior.south east)--++(-0.4,-0.1)--++(0.1,-0.2);     \path[fill=yellow!50!black,draw=none] (interior.south west) rectangle node[white]{\Huge\bfseries !} ([xshift=4mm]interior.north west);     },   drop fuzzy shadow,#1} \makeatother   \begin{document} \begin{marker}   Hylo! \end{marker}  \end{document}   This gives the following error  !

Why are tcbcol@back and tcbcol@frame undefined if they work in the code for the package's documentation? Alternatively, what are the correct names for the colours which were tcbcol@back and tcbcol@frame?  My version of tcolorbox is 2019-09-19. How to write a LaTeX package that bundles not only .sty and .cls files but also some logos in .pdf or .eps formats? I would like to make a LaTeX package with the following subdirs:   tex/latex/common (a common .tex file shared among beamer and letter) tex/latex/resources (lots of pdf and eps files with graphical resources) tex/latex/mybeamer (a custom beamer theme with 5 .sty files) tex/latex/myletter (a .cls file for a letter template)   I would like to package these files into a single LaTeX package that users could install in an easy way. I read about the .ins and .dtx files and I can see how to pack the .sty and .cls files but what about the extra graphics - the resources folder which contains several PDF and .eps files?
