How to put one symbol that spawns several itemized lines in Beamer Presentation? In Beamer presentation I have itemized block:  \begin{itemize}     \item object     \item type     \item action \end{itemize}   I was wondering if I could put one symbol - } that will spawn to several lines and then write one description after it. something like this:    I was looking for it but was not able to find anything similar. So any suggestion would be helpful.
How can I create a brace spanning multiple lines on the right side of an itemized list? I have an itemized list:  \begin{itemize}     \item Lorem     \item Ipsum     \item Sit     \item Dolor     \item Amet \end{itemize}   I want to create an accolade on the right side of 'Lorem' and 'Ipsum', and add a bit of text at the point of the accolade. The level of this text should be between the first and the second line. How can I get this done?
Evaluate the integral: $\int_{0}^{1} \frac{\ln(x+1)}{x^2+1} \mathrm dx$ Compute  $$\int_{0}^{1} \frac{\ln(x+1)}{x^2+1} \mathrm dx$$ What is data blending? This term appears frequently in the .  Is blending a specific method in data-mining and statistical learning? I cannot get a relevant result from google.  It seems blending is mixing up outcomes from many models and resulting in a better result. Is there any resource that helps me knowing more about it? cat line X to line Y on a huge file Say I have a huge text file (>2GB) and I just want to cat the lines X to Y (e.g. 57890000 to 57890010).  From what I understand I can do this by piping head into tail or viceversa, i.e.   head -A /path/to/file | tail -B   or alternatively  tail -C /path/to/file | head -D   where A,B,C and D can be computed from the number of lines in the file, X and Y.  But there are two problems with this approach:   You have to compute A,B,C and D. The commands could pipe to each other many more lines than I am interested in reading (e.g. if I am reading just a few lines in the middle of a huge file)   Is there a way to have the shell just work with and output the lines I want? (while providing only X and Y)? Using Illustrator CS6 to create shape out of multiple paths Prove that, $\frac{a}{b}+\frac{b}{c}+\frac{c}{d}+\frac{d}{a}\ge 4$ where we do not use AM-GM inequality on the given statement to prove it. The volume on my macbook pro has suddenly become greyed out. I haven't installed any updates or made any modifications to the computer, it just suddenly became greyed out after waking the macbook up from sleeping.  I've tried resetting the PRAM, but I don't hear any chime at all when I start up my computer, no matter how long I wait/how many times the computer re-restarts itself.  There also seem to be no internal speakers detected when I go into system preferences. For both input and output the computer detects 0 devices.  Thanks so much in advance for any help!!

Let $M$ be the manifold of real positive definite $n \times n$ matrices, define a mapping $i:A \to \sqrt A$ (where $A\in M$ and $\sqrt A$ means the unique positive definite square root of $A$). Please show that $i$ is smooth. addtocontents not working with certain other packages This is a follow up question on   How do I change the toc dept mid document while using packages (in this case only mathtools).  An example:  \documentclass[a4paper,10pt,oneside]{book}  \usepackage{mathtools}  \begin{document}   \frontmatter             \chapter{hello}  \section{hello}  \subsection{hello}  \subsubsection{hello}   \setcounter{tocdepth}{3}  \tableofcontents   \mainmatter   \chapter{hello}  \section{hello}  \subsection{hello}  \subsubsection{hello}   \chapter{hello}  \section{hello}  \subsection{hello}  \subsubsection{hello}   \appendix   \addtocontents{toc}{\setcounter{tocdepth}{0}}   \chapter{hello}  \section{hello}  \subsection{hello}  \subsubsection{hello}   \chapter{hello}  \section{hello}  \subsection{hello}  \subsubsection{hello}  \end{document}   This example generates an error and very strangely puts an exclamation mark in the ToC as you can see here   however when I comment out the \usepackage{mathtools} it suddenly works again or replacing it with a different package such as \usepackage[T1]{fontenc} also generates no errors.  But this is not limited to just this specific package, certain other packages also introduce the same behavior (I just took this package to keep the example small). Keep old kernels If you try to execute a program that is not installed you will get a message  The program 'x' is currently not installed. You can install it by typing:  sudo apt-get install x   and instead of offering you to install the program for you, you have to type the actual command. How can this behavior be changed? Let $n$ be a positive integer. Show that the matrix  $$\begin{pmatrix} 1 &amp; 1/2 &amp; 1/3 &amp; \cdots &amp; 1/n \\ 1/2 &amp; 1/3 &amp; 1/4 &amp; \cdots &amp; 1/(n+1) \\ \vdots &amp; \vdots &amp;  \vdots &amp; \ddots &amp; \vdots\\ 1/n &amp; 1/(n+1) &amp; 1/(n+2) &amp; \cdots &amp; 1/(2n-1) \end{pmatrix}$$  is invertible and all the entries of its inverse are integers. This is an exercise in Hoffman and Kunze's linear algebra book. Any hints will be appreciated! Retrieving minimum width that contains specified fraction of all values I'd like to find the min/max boundaries of a sliding window of minimum size that contains a certain fraction of the total number of elements in an array or collection of numbers.   Example: taking integers to make it easier to explain, say the proportion of elements that we're looking for is 50% on this array:  [1,1,2,3,3,3,3,3,3,4,5,6,7,8,9,10]  The mystery function would return something like ( 2, 4 ), meaning that the minimum value is 2 and the max value is 4 (let's assume it's inclusive and note that these are VALUES, not indices). That little window contains 8 of the 16 values and it's only 2 units wide, the narrowest such window that contains half the number of values.  Note: the quartiles are [1,1,2,3], [3,3,3,3], [3,4,5,6], [7,8,9,10] so they are NOT what I'm looking for.  I can code it...may take some time to get it nice. Hopefully somebody has run across it before. Does it have a name?  Is there an existing method that somebody knows about?  I am interested in Python implementations.   UPDATE:  Thanks to Glen_b who gave the names 'short-half' and 'shortest interval' I was able to come up with this: Money making in Runescape Consider the following figure from Faraway's Linear Models with R (2005, p. 59).    The first plot seems to indicate that the residuals and the fitted values are uncorrelated, as they should be in a homoscedastic linear model with normally distributed errors. Therefore, the second and third plots, which seem to indicate dependency between the residuals and the fitted values, suggest a different model.  But why does the second plot suggest, as Faraway notes, a heteroscedastic linear model, while the third plot suggest a non-linear model?  The second plot seems to indicate that the absolute value of the residuals is strongly positively correlated with the fitted values, whereas no such trend is evident in the third plot. So if it were the case that, theoretically speaking, in a heteroscedastic linear model with normally distributed errors  $$ \mbox{Cor}\left(\mathbf{e},\hat{\mathbf{y}}\right) = \left[\begin{array}{ccc}1 &amp; \cdots &amp; 1 \\ \vdots &amp; \ddots &amp; \vdots \\ 1 &amp; \cdots &amp; 1\end{array}\right] $$  (where the expression on the left is the variance-covariance matrix between the residuals and the fitted values) this would explain why the second and third plots agree with Faraway's interpretations.  But is this the case? If not, how else can Faraway's interpretations of the second and third plots be justified? Also, why does the third plot necessarily indicate non-linearity? Isn't it possible that it is linear, but that the errors are either not normally distributed, or else that they are normally distributed, but do not center around zero? What's the difference between "cardinal" and "ordinal" as adjectives? I have been editing an answer on , with some considerable amount of effort, and when I hit on Save Edits, the edit gets rejected with the following error. I got to know the meaning of this from .     The edit queue is full at the moment - try again in a few minutes!     I tried in a few mins, and still it didn't work. I believe that some edits might be valuable and this resists the users from doing so.   Main Question: Is there a way to show the queue limit at the beginning of the editing process? (So that we won't spend time on doing the edit, knowing it will fail) I just checked my server's /var/log/auth.log and found that I'm getting over 500 failed password/break-in attempt notifications per day! My site is small, and its URL is obscure. Is this normal? Should I be taking any measures? Am I technically allowed to look up cards during a Magic tournament match? Am I allowed to look up a card during a game, if it's being played with serious Rules Enforcement? Either to read the full card from the Gatherer, or to try to find the exact card I'm vaguely thinking of.  Two possible scenarios:   An opponent has revealed a card previously, and I want to remember the exact details. (Something like the exact wording of a sorcery, mana cost, keywords on a creature, subtypes, etc. etc.) I have a "name a card and remove it from the opponent's deck" type card, and I want to, say, ask google for "Blue Gearhulk" to remember that it's that that one is called "Torrential Gearhulk".   Obviously, in casual or semi-casual games neither of these are a problem. Any reasonable opponent will just re-reveal the known card (assuming it IS still guaranteed to be known) or will accept "I name the Blue Gearhulk".  Also obviously, it seems unlikely that I (or anyone else) would get to the stage of playing at the REL without knowing the cards too thoroughly for this to be relevant.  But in principle... is it permitted? Or not? (and if not, is there a good reason, or just "we decided 'No'"?) align vs equation
