Align the footer at the bottom with variable content height
CSS to make HTML page footer stay at bottom of the page with a minimum height, but not overlap the page
How can I let a footnote continue on the next page? I have a rather long footnote which breaks a listing in two parts, unnecessarily.  Since the listing is more important then the footnote I'd rather lake to have the footnote split.   Can I customize (one or all) footnotes to have a maximal length before they are continued on the next page? Or can I manually split a footnote in two to get the effect? Properties of $x_k=\frac{a_{k+1}-a_{k}}{a_{k+1}}$ where $\{a_n\}$ is unbounded, strictly increasing sequence of positive reals Why the value of $PATH is different for root and normal user? for normal user I get :     /usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/monty/google_appengine   which is actually the content of /etc/environment  For root I get:     /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin   what's the reason behind this and which file contains this line? Numbering of appendices in the backmatter of a book I'm using the standard book class. If I write  \documentclass{book}  \begin{document}  \frontmatter \tableofcontents  \mainmatter \chapter{foo} \section{Donald}  \backmatter \chapter{bar} \section{Mickey}  \end{document}   I expect to have chapter bar numbered as appendix A and section Mickey as A.1. Instead chapter bar is not numbered and section Mickey is 1.2, following section Donald. If I insert the appendix command to obtain  \documentclass{book}  \begin{document}  \frontmatter \tableofcontents  \mainmatter \chapter{foo} \section{Donald}  \backmatter \appendix \chapter{bar} \section{Mickey}  \end{document}   then chapter bar is unnumbered and section Mickey is numbered as .1.  What am I doing wrong? Ligatures in figures and pdftex I am looking for a single word for a person who is able to explain himself very clearly and using the best possible words, etc. I am not looking for "perspicuous", etc. The focus is more on the language part: someone who uses the right language and words to describe himself. I know the word exists but its just skipping my head at the moment!!! Please help. Can I insert an image into an equation? I would like to use a small image in an equation, where a symbol like \alpha might otherwise be. Is there a nice way to do this? ARMA/GARCH estimation in sequence System freezes completely with Intel Bay Trail $$\overline{z}=z^n$$ where $n\in \mathbb{N}$   So I have started with moving the polar representation as the expression is in the n-th power  $$rcis(-\theta)=r^ncis(n\theta)$$   I can not multiply both sides in $r^{(-n)}$ as $n\in \mathbb{N}$ how should I continue? Alphabetically display the items in itemize I am wondering whether it is possible to display the items alphabetically regardless of the order we type on the backend? For example I am using itemize as follows:  \begin{itemize}     \item ISDYNSTP:  Is dynamic time step used?     \item ISCDCA:     \item MVAR     \item IS2TL_ \end{itemize}   But I want to display the items in the alphabetical order. I don't know whether it is possible or not. I have like hundreds of itemize items. Actually I am trying to create a glossary for the different parameters. How can I add custom '.desktop' application launchers to Ubuntu Dock? How to redirect output of a running program to /dev/null I know that in order to suppress the output of a program I can redirect it to /dev/null, for example to hide all error and warning messages from chromium I can start the program like this  chromium-browser 2&gt; /dev/null &amp;   However, if I happen to forget about the error messages and type  chromium-browser &amp;   (which is quite annoying when they appear in the middle of a command) I don't know what to do except for stopping the application and starting it again properly.  Can I somehow redirect error output without restarting the application? For example, the square can be described with the equation $|x| + |y| = 1$. So is there a general equation that can describe a regular polygon (in the 2D Cartesian plane?), given the number of sides required?  Using the Wolfram Alpha site, this input gave an almost-square: PolarPlot(0.75 + ArcSin(Sin(2x+Pi/2))/(Sin(2x+Pi/2)*(Pi/4))) (x from 0 to 2Pi)  This input gave an almost-octagon: PolarPlot(0.75 + ArcSin(Sin(4x+Pi/2))/(Sin(4x+Pi/2)*Pi^2)) (x from 0 to 2Pi)  The idea is that as the number of sides in a regular polygon goes to infinity, the regular polygon approaches a circle. Since a circle can be described by an equation, can a regular polygon be described by one too? For our purposes, this is a regular convex polygon (triangle, square, pentagon, hexagon and so on).  It can be assumed that the centre of the regular polygon is at the origin $(0,0)$, and the radius is $1$ unit.  If there's no such equation, can the non-existence be proven? If there are equations, but only for certain polygons (for example, only for $n &lt; 7$ or something), can those equations be provided? Configuring ADB for Nexus 4 on Ubuntu 11.10 I'm trying to deploy and test an Android app on my Nexus 4 from my Ubuntu 11.10 computer, but ADB doesn't recognize it. I think I need the Google USB drivers, but I cannot find instructions on how to install them on Ubuntu.  How can I install the drivers on Ubuntu 11.10 so that ADB will recognize my N4? What's better here - a single column or multicolumn primary key? Let's assume you have a table groups and a table item. Each item belongs to exactly one group. It is an inherent part of that group. An item cannot exist outside of a group and it cannot be moved to another group.  When trying to decide on a primary key for the item table, what should I use?  Should I make up an artificial global serial key like this:  CREATE TABLE items (     item serial PRIMARY KEY,     group integer NOT NULL REFERENCES groups(group), );   ... or should I rather use a composite key and per-group item serial like this:  CREATE TABLE items (     group integer NOT NULL REFERENCES groups(group),     item integer NOT NULL,      PRIMARY KEY(group, item) );   The reason why I'm leaning more towards the second solution is that the post URL will always show the group and item, so it makes sense to have both of them as the composite primary key. In case of the first solution, the URL contains superfluous information because the group ID can already be deduced from the item ID alone. The URL structure is given, however, and cannot be changed.  The disadvantage of the second solution is that you have to manage a per-group serial (i.e. each item integer should start from 0 for each group).  What's better in terms of best practices, normalization and performance? Or is it simply a matter of taste? How to fully stop UAC Windows 8 I have a problem, i have a Windows 8 realease Preview. I have UAC turned off always, but for test i switched UAC on (slider up) and restarted my pc, then, i turned it off (slider down) and restarted my pc. And now have a problem, all .exe files starts without admin privileges (my pc user is administrator). How can i fix that?  Thanks!
