I have Picture X.Y:Photo1 and I am using  \label{pic:Photo1}   and   \ref{pic:Photo1}   to reference it. The outcome is something like: ...which you can see in picture X.Y. When I click on X.Y it is supposed to display the Photo1, but there is only its caption on top of the displayed part of page and I have to scroll a bit to see the picture itself. I want the picture to be shown right after clicking on the reference. Is there a way to do this? Thanks in advance.
I'm using the following command to embed images in my LaTeX document (which is then rendered as PDF)  \newcommand{\img}[4]{   \begin{figure}[!hbt]     \centering       \vspace{1ex}       \includegraphics[width=#2]{images/#1}       \caption[#4]{\label{img.#1} #3}     \vspace{1ex}   \end{figure} }   When creating a href to an image, the viewer jumps to the image caption instead of the top of the image. How do I change my \img command so it still puts the caption below the image but links to it jump to the image itself?
What is the best way to explain how to choose between "its" and "it's"? The choice field adds a blank option in all my sharepoint lists. How do I remove this? the column settings does not have a blank option. At what times before $1{:}30$ in the afternoon do all three doctors schedule their appointments to begin at the same time? In a certain medical group, Dr. Schwartz schedules appointments to begin $30$ minutes apart, Dr. Ramirez schedules appointments to begin $25$ minutes apart, and Dr. Wu schedules appointments to begin $50$ minutes apart. All three doctors schedule their first appointments to begin at $8{:}00$ in the morning, which are followed by their successive appointments throughout the day without breaks. Other than at $8{:}00$ in the morning, at what times before $1{:}30$ in the afternoon do all three doctors schedule their appointments to begin at the same time?  I'm not sure how to approach this question. They all begin at the same time at $8{:}00$. Also doesn't the overlapping of appointments depend on how long their respective appointments take? UV mapping not filling faces How to assess the similarity of two histograms? Given two histograms, how do we assess whether they are similar or not?  Is it sufficient to simply look at the two histograms? The simple one to one mapping has the problem that if a histogram is slightly different and slightly shifted then we'll not get the desired result.  Any suggestions? I'm trying to deactivate/remove/uninstall a default Client Side Web-Part (the Yammer one) in modern pages and I don't find a way to do it:    I would like the Yammer option to be not visible in the menu. Any ideas?  Thank you very much in advance! Let $\phi : R \to S$ be a homomorphism. If $N$ is an ideal of $S$, then $\phi ^{-1} (N)$ is an ideal of $R$. Beamer keeping line position constant on itemize I want to have a slide in beamer with itemize exposing new line on each click while at the bottom part of the slide there are some equations. This is my attempt  \begin{frame}   \begin{overprint}{\textwidth}     \leavevmode     \begin{itemize}[&lt;+-&gt;]     \item &lt;1-&gt; Poisson Boltzman equation (PB)     \item &lt;2-&gt; Debye-H\"uckle equation  (DH)     \item &lt;3-&gt; The naive approach - applying (DH) equation to PE     \end{itemize}   \end{overprint}   \begin{tikzpicture}     \node at (0,0) {};         \node&lt;1,2&gt; [text width = 20cm]at (10.5,-1) {$ \nabla^2 \phi =\sum_i \frac{n_i q_i\text{e}^{-q_i \phi/kT}}{4 \pi \epsilon}$};         \node &lt;2&gt; [text width = 20cm]at (10.5,-2) {$q_i \phi/kT \ll 1 \Rightarrow \nabla^2 \phi \simeq \kappa^2 \phi$};         \node &lt;2&gt; [text width = 20cm, font=\footnotesize]at (10.5,-2.5) {$\kappa^2 = \lambda^{-1/2} =  \sum_i \frac{n_i q_i}{4 \pi \epsilon}$};         \node &lt;3&gt; [text width = 20cm] at(10.5,-1) {$\frac{F_{el}}{VkT} = - \left ( \frac{ 4 \pi e^2}{\epsilon kT}     \sum_{i=1} n_i z_i^2 \right )^{3/2} \left ( 12 \pi \right )^{-1}$};   \end{tikzpicture} \end{frame}   However, the itemized line jump up and down between slides. I've tried to use itemize without any environment surrounding it. I've also tried to use overlayarea instead of overprint. How can I keep the line position constant?  I've uploaded a gif animation to display this. On my machine it run really fast and I can't fix this. Hope the problem is understood.   When I run this, I get Could anyone explain why the number of legal or reachable combinations of a $3\times 3\times 3$ Rubik's Cube is $1/12\mbox{th}$ of the total. I understood the logic behind the total number of combinations: $8! \cdot 2^{12} + 3^{12} \cdot 12!$. What I am not able to understand is why do we divide this quantity by $2 \cdot 3\cdot 2$. I don't have any idea about parity or group/set theory. Is there another possible explanation for it? Unknown Column In Where Clause I have a simple query:  SELECT u_name AS user_name FROM users WHERE user_name = "john";   I get Unknown Column 'user_name' in where clause.  Can I not refer to 'user_name' in other parts of the statement even after select 'u_name as user_name'? Appearing on the second page (under the section Digression: Size worries) of the following paper about the Yoneda Lemma:     It says that $a$ $priori$ $[\mathcal C^{op},Set](H_A,X))$ is a class. I don't understand why this is the case.  My understanding is that $a$ $priori$ each member of $[\mathcal C^{op},Set](H_A,X))$ is a class.  So it seems to me that $[\mathcal C^{op},Set](H_A,X))$ could be a collection of proper classes.  I've looked at this , but it hasn't helped me much.  Any help is appreciated -Thanks When should I use "in" or "on"? As it is common with people from my country, I have an immense difficulty with prepositions in English, especially with the use of in and on.   When the preposition indicates the position of the object it is a bit easier to decide which one to use, but as it requires thinking from me, I still say things like "I put the bill in the fridge", "my pencil is on my bag", etc, even though if I think about it, I would know how to say it correctly.  Of course, even in those cases where the preposition indicates position the decision is not always clear, as is the case for example with "on the bus" (you are not on top of the bus, you are inside the bus) or "he is in bed" (you are not inside the bed, you are on top of your bed).  Other cases are even less clear, and I believe there is no real rule to decide what should be said; the person should just know it. Two examples are "in a bad mood", "you are on my mind".  So my first question is whether there is really no rule to help me. The second question refers to two of the cases where I still don't know whether to use in or on:   good luck on/in your exam in/on the list   The last one is especially important to me, as I have asked a number of native speakers, and each time I get a different answer. The only consensus seems to be the case where you say "on top of the list". Apart from that, some people will say that I should say "his name is in the list" whereas others think I should say "his name is on the list". And yeah, a couple of people did tell me that I can use either.  Can someone help me? Can I travel to UK with my Italian national daughter and husband with my permesso di soggiorno? I have an Italian permesso di soggiorno and I want to join my husband in the UK. My baby and my husband are Italian nationals. Can I travel with them with only the permesso di soggiorno? How can you encode a string to Base64 in JavaScript? I have a PHP script that can encode a PNG image to a Base64 string.  I'd like to do the same thing using JavaScript. I know how to open files, but I'm not sure how to do the encoding. I'm not used to working with binary data. command to display time (duration) in human readable form I spent 3 hours trying to write a command to format a time (duration) expressed as a floating number (in seconds) in a nice form as follows:  if the time is &lt; 60 write as a float with 3 decimals (i.e. milliseconds)  else let h,m,s be the hours, minutes and seconds corresponding to the time      if h=0 then write as m:ss (ss always with 2 digits, m can have only 1)      else write h:mm:ss (mm and ss with 2 digits, h can have only 1)   So 1.25678 gives 1.256, 125.35 gives 2:05, 18249 (which equals to 5*3600+4*60+9) gives 5:04:09.  I tried several packages for the comparison/formatting. No success. Can someone help me ? Thanks ! Reload the page on hitting back button I have a very strange behavior on an Android device (Nexus 7) when trying to access local network applications. Instead of getting the actual IP of the machine on LAN, the Android device gets the public IP, which means that Chrome, Firefox or any other browser simply shows the web page of the router.  I have an internal DNS server which handles the local networks. Doing ping from a PC works correctly:  $ ping s.pelicandd.com  PING pelicandd.com (192.168.1.15) 56(84) bytes of data. 64 bytes from front.pelicandd.com (192.168.1.15): icmp_seq=1 ttl=64 time=0.524 ms 64 bytes from front.pelicandd.com (192.168.1.15): icmp_seq=2 ttl=64 time=0.578 ms ^C   On an HTC One device (accessed with adb shell), it works well too:  shell@m7:/ $ ping s.pelicandd.com  PING pelicandd.com (192.168.1.15) 56(84) bytes of data. 64 bytes from front.pelicandd.com (192.168.1.15): icmp_seq=1 ttl=64 time=2.56 ms 64 bytes from front.pelicandd.com (192.168.1.15): icmp_seq=2 ttl=64 time=27.8 ms ^C   However, this is what I get when doing the same ping from Nexus 7:  shell@flo:/ $ ping s.pelicandd.com  PING pelicandd.com (90.78.26.42) 56(84) bytes of data. 64 bytes from LFbn-1-2441-42.w90-78.abo.wanadoo.fr (90.78.26.42): icmp_seq=1 ttl=64 time=2.56 ms 64 bytes from LFbn-1-2441-42.w90-78.abo.wanadoo.fr (90.78.26.42): icmp_seq=2 ttl=64 time=8.63 ms ^C   Instead of resolving to the internal IP, it resolves to the public one.  The network configuration is—except the IP address of the device—exactly the same on both devices: IP settings are set to Static, and DNS servers are the internal ones. Both Android devices are connected through Wi-Fi (unlike the PC). A major difference, however, is that Nexus 7 is using Android 6.0.1, while HTC One uses Android 5.0.2.  There is no nm-tool, dig or nslookup on Nexus 7. The device is not rooted.  The problem existed since I bought the device a few weeks ago, so it could hardly be the issue with DNS cache.  What can I do to further inspect this issue? Pronunciation differences between "finite" and "infinite" In my experience, "finite" is pronounced (IPA) ˈfaɪnaɪt while "infinite" is ˈɪnfɪnɪt.  In general, the prefix "in" negates an adjective, but does not change the pronunciation. Based on this, I would expect ˈɪnfaɪnaɪt.  Is there a reason for this "deviation from the norm"? Are there dialects/regions that actually say ˈɪnfaɪnaɪt (or ˈfɪnɪt, for that matter)? A word for someone who you share a half-sibling with This is probably best explained with an example.  Alice and Bob have a child, Erin. Bob and Carol have a child, Frank. Carol and Dan have a child, Grace. Clearly, Erin and Frank are half-siblings, because of their father, Bob. Similarly, Grace and Frank share their mother, Carol.  Erin and Grace have no parents in common, and are thus not half-siblings. However, is there a term for their relation? The following is an old qualifying exam that I cannot solve:  Suppose $f$ is holomorphic on the punctured unit disk and $ \frac{f '}{f} $ has a simple pole at $0$.  Show that $f$ does not have an essential singularity at $0$.
