I am preparing my slides using beamer. My working code is as follows: \documentclass{beamer}  \usepackage{pgf,tikz,tikz-cd}  \usetikzlibrary{calc, arrows, backgrounds, fit, positioning, quotes, shapes, shapes.geometric, intersections, decorations.pathreplacing}  \begin{document}     \begin{frame}[fragile]         \frametitle{Introduction}         \framesubtitle{Background and motivation}         \begin{figure}[h!]             \label{figure:maptoR}             \begin{center}                 \[                 \begin{tikzcd}[cells={nodes={circle,align=center,inner sep=1pt,                             text width={width(&quot;$\mathrm{Row}_i\times\mathrm{Row}_i$&quot;)},draw,                             path picture={\path[ball color=gray!60,fill opacity=0.4]                                 (path picture bounding box.center)                                  circle[radius={width(&quot;$\mathrm{Row}_i\times\mathrm{Row}_i$&quot;)*1pt}];                     }}},                     bend angle=50,every arrow/.append style={-stealth,bend left},                     every label/.append style={font=\normalsize},                     sep=small]                     M_n\times M_n \arrow[r,&quot;R_i&quot;]                     \arrow[rrrr,bend right=25,&quot;\succ&quot;,start anchor=-60,end anchor=-120]                     &amp;  \mathrm{Row}_i\times \mathrm{Row}_i \arrow[r,&quot;\omega_{ij}&quot;]                     &amp; M_n \arrow[r,&quot;\omega_{ij}'&quot;]                     &amp; M_{1\times n} \arrow[r,&quot;\omega^*&quot;l]                     &amp; \mathbb{R}\\                 \end{tikzcd}                 \]\caption{Composition of function $\succ$.}             \end{center}         \end{figure}     \end{frame} \end{document}  which produces:  What do I need to do so that the figure fit in the frame nicely? Please help.
Question:     I want to scale a tikzcd diagram, but it doesn't seem to be working. It always compiles in a small scale. How does one scale a tikzcd diagram to, say, large scale?   Attempt:   I tried to set the option scale but it doesn't do anyhting.   \documentclass{article}  \usepackage{tikz} \usepackage{tizk-cd}  \begin{document} \begin{tikzcd}[scale=2.7em]  X \arrow{d}[swap]{\mathcal Q} \arrow{r}{f}  &amp;Z \\   Y \arrow{ru}[swap]{\bar f} &amp;{} \end{tikzcd} \end{document}    I've also read the manual  but I don't understand how to use the command /tikz/commutative diagrams/ row step=\langle size \rangle or its variances. I believe I'm using the latest version of tikz-cd and pgf files.   Note: I'm not interested in tikzpicture or similar environments, I'm working with tikzcd.
After the latest Win8.1x64 Updates, my system got stuck restarting or shutting down.. When I installed the last Windows update, all seemed fine except it got stuck doing the restart.  I waited about 5 minutes then used the power button.  Startup was normal.    But then when I told it to shut down it closed the programs then went to the "Shutting Down" screen and just stays there.    Disk activity lights aren't showing any activity.  Here is a screen grab of the most recent updates:    Before I do anything I wanted some input.  Question:  Any ideas of how I can figure out how to fix it? If a lightning-radio-group has two options, and a user selects one, I want to programmatically have the UI changed back to the other one.  Link to a . (code copied below)  import { LightningElement, track } from 'lwc';  export default class RadioGroupRequired extends LightningElement {     @track value = 'option1';      get options() {         return [             { label: 'Option one', value: 'option1' },             { label: 'Option two', value: 'option2' },         ];     }      handleOnChange(evt) {         this.value = 'option1';         // how to make the UI select Option one?     } }   And the html:  &lt;template&gt;     &lt;lightning-radio-group name="radioGroup"                            label="Radio Group"                            options={options}                            value={value}                            required                            type="button"                            onchange={handleOnChange}&gt;&lt;/lightning-radio-group&gt;                             value={value} &lt;/template&gt;     I think that there is no rerendering because the bind variable, {value} doesn't actually change. However, the selected state of the lightning-radio-group does, and I want to be able to change it back. How can that be achieved?   I did not notice any methods or attributes that would seem to do the trick in the . What should I do when a hacker gives me hacked money? I was peacefully playing GTA Online (yeah, was killing someone coming out of ls customs) then a hacker came and killed me using explosive ammos, I called him a hacker and he teleported to me and gave me 790k. I know that people get banned for receiving this kind of money, what should I do to avoid the ban? Changing the homepage Reward for Passing Review tests? Just wanted to see what the community thought of adding a reward to passing the review tests? Maybe a 1 point reward?  I know seeing the tests in the review area has helped me be extra careful when reviewing, but I thought perhaps a little boost in incentive would be cool. Proof by induction: $\sum\limits_{i=1}^{n} \frac{1}{n+i} = \sum\limits_{i=1}^{n} \left(\frac{1}{2i-1} - \frac{1}{2i}\right)$ How can the following be proved by induction?  $$\sum\limits_{i=1}^{n} \frac{1}{n+i} = \sum\limits_{i=1}^{n} \left(\frac{1}{2i-1} - \frac{1}{2i}\right)$$ I am out of ideas after practicing for a while:  $$\frac{1}{n+1}+\frac{1}{n+2}+\dots+\frac{1}{2n}=\left(1-\frac{1}{2}\right)+\left(\frac{1}{3}-\frac{1}{4}\right)+\dots+\left(\frac{1}{2n-1}-\frac{1}{2n}\right) $$  Does this involve telescoping series? Sample query/DDL for producing page locks on a clustered index in SQL Server (without hints) We currently have some indexes where ALLOW_PAGELOCKS is set to off. This presumably was done in order to reduce deadlocks. However I doubt that it would really had an effect back then.   Now I am trying to understand WHEN SQL Server actually chooses to start locking pages rather than keys in a clustered index. I asked Jonathan Keyhaisas recently and he told me that this could happen if I am touching rows on several subsequent pages. However I didn't manage to get any exclusive page locks by updating rows in a clustered index with a sample query.   Could you help me understand page locks better with a sample query and table? I am running SQL Server 2008 SP4.  Thanks in advance  Martin Do SAS expanders work transparently with SAS controllers? I'm new to SAS expanders and I'm trying to get things right. I understand that SAS expanders, when used with SAS controllers which supports expanders, allows you to utilise the full capacity of supported drives on a controller.  However, say I've got a SAS controller with 4 x SSF-8087 ports, which by itself would support 16 disks. I could then, as far as I understand, instead connect each of these ports to an expander to increase disk capacity.  However, will the SAS controller "see" all disks as if they were connected directly to the controller and not through an expander. Could I look at controllers as switches in a network? Would I be able to create a RAID from a disk on expander 1 and expander 3?  UPDATE:  I don't really have a specific project where I need to use SAS expanders. I'm just curious about how they work, and was thinking about how it would work if I used one or more SAS expanders with a LSI MegaRAID controller (9260-16i) which is running in one of our servers. However, I haven't really put any thought into the distinction between "local" disks and disks in another enclosure. The LSI MegaRAID controller has 4 SFF-8087 ports, which makes it capable of accomodating 16 drives. It was suggested to me recently that Annihilator sacrifices (such as 's) are only chosen during resolution, rather than while they're going on the stack.  Do I choose those sacrifices during resolution? What part of the comprehensive rules backs that up?  I can't find any clarity on the internet, in the rules, on the MTG Salvation wiki for Annihilator, or in the ability's rulings. It seems reasonable, but I'd like to know what's behind it. Plus, if I can choose and then later  some stuff, all the better. Converting HTML to plain text in PHP for e-mail I'll be traveling to Germany this May and my planes would arrive at 4 May 20.30 at Frankfurt Airport but the Schengen visa that I received is valid only at 5 May.  Is it possible to enter if it's only a few hours before the day change? Or do I have to wait until day change in the transit area?  Another thing, would the airline rejected me from boarding the plane? What effect does serial downvoting have on my rep cap? I'm trying to mount my HDD,  /dev/sdb, which is connected via an enclosure but every time I try do so I get an error message   mount: /dev/sdb: can't read superblock   How do I solve this problem and mount my HDD? I've been asked by some schoolmates why we have $$ \sum_{n=0}^\infty \frac{1}{n!}=e.$$ I couldn't say much besides that the $\Gamma$ function, analytic continuation of the factorial, is defined with an integral involving $e$. Then I also know that actually $$ \sum_{n=0}^\infty \frac{x^n}{n!}=e^x.$$ Is there a reason for these facts?  P.S. I added the tag "intuition", please remove it if you think it is not pertinent. How to favorite a question from Android app? I've found an interesting question when browsing Freelancers.SE. I've tried to star (favorite) the question but I couldn't find the option...  How to star a question from the Android app? Introductory measure theory textbook I would like to teach myself measure theory and I am looking for a good introductory textbook at the advanced undergraduate or early graduate level. A reader-friendly text with plenty of examples would be ideal. It seems amongst is quite often used as a synonym for among but it is supposed to sound more distinguished. Is there any difference in the meaning? When is "seems to be" used instead of "seems"? The baby seems happy/comfortable. The baby seems to be happy/comfortable.   Are these both correct? If both are correct, what are the differences between them? Move Lifejacket and Lifeboat to Answer Badges section in Help Center The new blog post  mentions the new badges  and  are answer badges, but they are listed on the  under Question Badges:    Since you earn these primarily by posting an answer (you're not required to do anything about the question, though editing it will probably help), they definitely belong to the Answer Badges. The Data Interoperability Tools .tbx appears in my system toolboxes, however when I double click quick export or import, a red X appears.  I have gone into the administrator settings and the tool doesn't appear to be installed. How do I install it?  I am using ArcGIS 10.2 for desktop trial.  After I attempt to evaluate extensions, I receive a message which states all requested features have already been authorized on this machine.
