In the example below (when changed to beamer mode) there is a frame with two slides.  On the first slide the text "Text 1" is shown in red color.  On the second slide it is shown in blue color (default).  \documentclass[10pt,t,handout]{beamer} \usepackage[english]{babel} \begin{document} \begin{frame}&lt;handout:2&gt;    {\color&lt;1&gt;{red}Text 1}    {\color&lt;2&gt;{green}Text 2} \end{frame} \end{document}   For the creation of handouts, however, I have added an overlay specification to the frame environment to only include slide 2 in the handouts.  I would assume that the generated slide in the handout would have "Text 1" in blue and "Text 2" in green.  Surprisingly for me the result in the handout is a slide where "Text 1" is red and "Text 2" is green.  This brought me to my question: What is the meaning of an overlay specification for handout mode that is added to a frame environment?  Please note: I already found a workaround, namely to provide individual overlay specifications for handout mode to the \color command for "Text 1":  {\color&lt;1| handout:0&gt;{red}Text 1}   That is, I am not asking to figure out how to make it work - I rather want to understand the background.  Update: Although I had searched SE before, only after submitting I was pointed towards this question: .  The background is, that the line  {\color&lt;1&gt;{red}Text 1}   actually means  {\color&lt;1| handout:1-&gt;{red}Text 1}   Thus, if I change the line to  {\color&lt;all:1&gt;{red}Text 1}   then the handout is generated as I had expected.
I have a beamer frame with about 150 slides on it.  I want article and handout mode to only show frame 92.    Reading section 8.6.2 of the beamer manual it seems like I should be able to do something like  \begin{frame}&lt;handout:92&gt; ... \end{frame}   but that seems to have no effect--all 150 slides are set in handout mode, overlaying (making the result unreadable).  I have gotten the effect I want by taking all commands within the frame that have an overlay specification and adding "| handout:0" to make them not appear in handout mode.  Annoying, but works.  But for my 150-slide frame the different slides are generated by a PGF \foreach loop so I can't code slide 92 differently from the rest.  But can I do this at the frame's overlay specification?  It seems that the frame's overlay spec really acts differently from other commands.  If I only do  \begin{frame}&lt;92&gt;...\end{frame}   then I get only slide 92 in beamer mode but all slides in article or handout mode.
What I am trying to do is to set a date in my date field and also update the object. I am using the class below to do so which works just fine in my sanbox but in production I am getting this error:      System.LimitException: Too many query rows: 50001   public with sharing class updateObject{     public  List&lt;NRProducts__c&gt;  values;     public PageReference updateObject() {         values=[SELECT Refreshed_Date__c FROM NRProducts__c ];         for (NRProducts__c s :values){            s.Refreshed_Date__c =Date.today();          }          update values;         return null;                       }     }   VF Page:  &lt;apex:page showheader="false" controller="updateObject" sidebar="false"&gt; &lt;apex:form&gt;  &lt;apex:commandButton action="{!updateObject}" value="Update"/&gt; &lt;/apex:form&gt; &lt;/apex:page&gt; Have a web-part display only sub-folders? I am new to SharePoint 2013. I was curious how to put a WebPart for a Document Library on a page with SharePoint 2013, not 2010.   This WebPart would then show the content of a specific library folder and not start at the root of the folder. So say I have a library with multiple folders like "Marketing", "Finance" etc,   I want to be able to create a web part that would only show the contents within the “Marketing subfolder and all of it contents. Is this possible? Can a plan "age" reach zero? If I want to solve the equation $4x = e^x$, is there a way to solve for $x$ without graphing and looking for intersection? Batch files: How to read a file? How you can read a file (text or binary) from a batch file? There is a way to read it in a binary mode or text mode? Why does $\lim\limits_{t\to-\infty}te^t=0$? Intuitively, $\lim\limits_{t\to -\infty}te^t=0$, since $e^t\to 0$ much faster than $t\to -\infty$.   Is there a way to more rigorously compute this? Writing it as $e^t/(1/t)$ seems resistant to l'Hopital's rule. Rotate single PDF page when viewing I got a Latex document which renders fine, some content is rotated using the turn environment from the rotate package. Everything works like it should.  Except: It know that it is possible to display a single page in a pdf in another orientation. The document viewer then rotates this page when viewing. This would help the readers of my document to read the turned text.   How is this possible? Perhaps somehow using the pdfpageattr command?   Again: I do not to want to rotate the content, I just want to tell the PDF-Reader that it should rotate the page when displaying. Show that $a \star b=a \cdot b+a+b$ is binary operation for the group $\Bbb{ Q} \setminus \{-1\}$ The group $\left(\Bbb{ Q}\setminus\{-1\},\star\right)$ has as its underlying set the rational numbers different from $-1$ and the operation $\star$ is defined as $a \star b=a \cdot b+a+b$ where multiplication/addition are the usual operations with rational numbers.Show that this is a binary operation.  What I did (Please help verify):  identity element has to be 0 since $a\star 0 = a+0+a(0)$ so for $a\star b=0$ we have  $ab+a+b=0$ $$ab+a=-b \\ a(b+1)=-b \\ a=\frac{-b}{b+1}$$ so $b$ cant be $-1$ since that solution is not in $\Bbb{Q}$. Similar question might have been answered here. Is this operation true for all groups? I think so.  Thanks for the tips and help. Let $P$ be a probability measure on $(\Omega, \mathscr{F})$, If $a,b,\in\mathscr{F}$ and $A\subset B$, then $P(B)-P(A)=P(B\setminus A)\ge 0$.  So far I have:  $A\subset B \implies B\setminus A = B\cap A^c = \emptyset$ as $A$ and $B^c$ are disjoint. Since $A\cup (B\setminus A)=A\cup (B\cap A^c)=(A\cup B)\cap (A\cup A^c)=B\cap\Omega = B$  Then for $A,B\in \mathscr{F}\implies P(A\cup (B\setminus A))=P(A)+P(B\setminus A) = P(B)$ by countable additivity.  Rearranging, $P(B)-P(A)=P(B\setminus A) \ge 0$. Why do stars flicker? Why do stars flicker and planets don't? At least this is what I've read online and seen on the night sky. I've heard that it has to do something with the fact that stars emit light and planets reflect it. But I don't get it, isn't this light, just "light"? What happens to the reflected light that it doesn't flicker anymore?  I was thinking that it has to do something with Earth's atmosphere, different temperatures or something (if this has any role at all). Intuitive explanation of unit root How would you explain intuitively what is a unit root, in the context of the unit root test?   I'm thinking in ways of explaining much like I've founded in .  The case with unit root is that I know (little, by the way) that the unit root test is used to test for stationarity in a time series, but it's just it.   How would you go to explain it to the layperson, or to a person who has studied a very basic probability and statistics course?  UPDATE  I accepted whuber's answer as it is what most reflect what I asked here. But I urge everybody that came here to read Patrick's and Michael's answers also, as they are the natural "next step" in understanding the Unit Root. They use mathematics, but in a very intuitive way. New Google SEO benefit with SSL - with only a few sections in SSL, or always on? I built a model of multiple linear regression to predict the revenues at the box office of a movie: the variable $Y$ is revenue while the variables $X$ are two: Activity (number of tweets per day) and sentiment (connotation of these tweets).  The problem is that the intercept is not significant. I thought of a possible explanation: the intercept in practice is the value of the variable $Y$ when the variables $X$ assume values of 0; but because of the very strong development of social networks, it is virtually impossible not to have even a tweet (and then a wave of activity) about a movie that just came out, I thought that the significance or not the intercept could be neglected because the assumed value has no meaning in reality (a tweet of 0 would never be satisfied, given the market today). In this way, I consider the intercept a mere constant for the calculation of the line, without worrying about its significance (because in some cases would take negative values, which is impossible for revenues).  The interpretation may be correct? Can a goalkeeper chip the ball to the head of a teammate from a goal kick to circumvent the backpass restriction? How do I get console output in C++ with a Windows program? Do we actually get more sick (flu/cold) during winter? The word flu derives from the Italian phrase "influenza de freddo" meaning "influence of the cold".  Indeed it is that time of the year when my colleagues seem to have the flu/cold more often than not. I remember during university, winter lectures would be riddled with people coughing and sneezing - the so called "freshers flu"  Questions   Is there statistical evidence for this claim? If so, what are the causes/factors involved?   asks why our noses get runnier during cold whether, is this related? Proof explanation $A\setminus B = A \setminus B \cap A$ $A\setminus B = A \setminus B \cap A$  Proof $A\setminus B \subseteq A \setminus B \cap A$:  $x\in A\setminus B \to x\in A \land x \notin B$  $x\in A \land (x \notin B \color{red}{\lor x\notin A})$  $x \in A \land (x\notin B \cap A)$  $x \in A\setminus B\cap A$  Proof $A \setminus B \cap A \subseteq A\setminus B$:  $x \in A \setminus B \cap A \to x\in A \land x\notin B \cap A$  $x \in A \land (x\notin B \color{red}{\lor x\notin A})$  $x \in A \land x \notin B$  $x \in A \setminus B $  Therefore $A\setminus B = A \setminus B \cap A$  I am confused how the stuff in the red is formed. Can we add an or statement to anything and ignore if its true or not if the first part of the or is true? How to close/open a view panel I can't find a way to close a view panel, in particular the horizontal at the bottom, is pretty useless to me at this moment. I would really love to play wizard/warlock multiclass with low charisma (just 13 for mutliclass). The handbook says that I can use Pact Magic slots to cast wizard spells, but doesn't specify which ability I use for spellcasting.     Pact Magic.   If you have both the Spellcasting class feature and the Pact Magic class feature from the warlock class, you can use the spell slots you gain from the Pact Magic feature to cast spells you know or have prepared from classes with the Spellcasting class feature, and [vice versa].   When I cast wizard spells using Pact Magic slots (or warlock spells using wizard's "Spellcasting" slots) do I use spellcasting ability of the slot, or do I get to choose? Show that the sequence $a_0 = 1$, $a_{n+1 }= \sqrt{2+a_n}$ is monotonically increasing Given the sequence $a_0 = 1$, $a_{n+1}= \sqrt{2+a_n}$, how can I show that it is monotonically increasing?  I need it to show, that the sequence converges. I already proved boundedness but I can't figure out this last part.
