I have set up Firefox Sync on several devices. I can give a name to each device, but, I could find no way to see the list of devices which I already synced. How can I get this information?
I`m using Firefox Sync on a bunch of computers.   I would like to manage my account, by removing some computers. I can't find the place to do this, it should be on the Firefox Sync page, but the official page only has the privacy and download information.
Showing that a finite abelian group has a subgroup of order m for each divisor m of n I have made an attempt to prove that a finite abelian group of order $n$ has a subgroup of order $m$ for every divisor $m$ of $n$.     Specifically, I am asked to use a quotient group-induction argument to show this.  I'd appreciate comments on the validity or lack thereof of my attempted proof below.  Let $G$ be a finite abelian group of order $n$ and let $m$ be a divisor of $n$.  The proposition is true for $n=1$, so we'll proceed by induction and assume $n \ge 2$.  Let $p$ be a prime dividing $m$ and let $x$ be an element of order $p$ in $G$ (which exists by Cauchy's Theorem for Abelian Groups).  By the induction hypothesis, $G/\langle x \rangle$ has a subgroup of order $\dfrac{m}{p}$.  This subgroup is of the form $H/\langle x \rangle$ for some $H \le G$.  Since $|H/\langle x \rangle| = \dfrac{m}{p}$, it follows that $H \le G$ has order $m$.  I chose to use a prime divisor of $m$, but I don't see why it wouldn't work to use any proper divisor of $m$.  Am I correct on this point?  Thanks, I appreciate the help. Which Stack Exchange site is best for AutoCAD questions? $R^2$ of 1 but RMSE > 0 The other day I was trying to download something for Minecraft and it involved my bin folder. So I was looking for it and couldn't find it. I then thought that I might have accidentally deleted it, but didn't find it in the trash. I have no idea how to get the bin folder back with all the Minecraft binary files in them. How to install Windows 7 after Ubuntu and dual boot? If you draw two circles that are exactly the same in all aspects (location, size, etc...) except they have different colors, then the "border" of the underlying circle is showing through.  \documentclass[10pt]{book} \usepackage{xcolor} \usepackage{tikz}  \begin{document}  \begin{tikzpicture}     \fill (0,0) circle (0.1);     \fill[color=red] (0,0) circle (0.1);     \fill[color=red] (0.5,0) circle (0.1); \end{tikzpicture} \end{document}   Notice the first circle has a black "edge" around it that looks different than the 2nd circle which doesn't.   The problem is due to the fact that one is anti-aliasing both circles and the edge colors are being blended.   Is there a way to fix this but still have anti-aliasing? (basically render all the objects I need then anti-alias them properly afterwards?)  (I realize TikZ probably can't do anything about this but one doesn't know unless they ask) the dinner vs. dinner (grammar question) From the sitcom  (episode ):     KRAMER: (scanning a menu) So, how was the dinner last night?   JERRY: Oh, well…   KRAMER: Did you enjoy the duck? (Elaine comes over…) Oh, Elaine! I was just   asking how dinner went last night.   ELAINE: (sitting down) Oh, well…   KRAMER: Alright, what did you do to Poppie?   ELAINE: Nothing.   KRAMER: Well, he's in the hospital. And the cook says you put him there.   ELAINE: What's wrong with him?   KRAMER: I don't know. I'm gonna go and visit him later. It would be nice if   you got him something. (Punches the table to accentuate this and leaves.)   JERRY: We should get him something.   ELAINE: Yeah. You're right.   I don't understand why Kramer first says the dinner, but when he says it a second time, he drops the article. What's the reason behind that? Why we don't use gamma rays, x-rays or ultraviolet to transmit data? The greater the frequency range of a transmission medium, the greater the number of bits per second it can transmit. In other words, the bigger the bandwidth in hertz available, the bigger the bandwidth in bits per second that can be transmitted.  Given that, why we don't use gamma rays, x-rays or ultraviolet to transmit data instead of e.g. visible(light) in optical fiber or microwaves(cell phones)? I have HTML code like this :  &lt;div&gt;        &lt;a&gt;Link A1&lt;/a&gt;        &lt;a&gt;Link A2&lt;/a&gt;        &lt;a&gt;Link A3&lt;/a&gt; &lt;/div&gt;  &lt;div&gt;        &lt;a&gt;Link B1&lt;/a&gt;        &lt;a&gt;Link B2&lt;/a&gt;        &lt;a&gt;Link B3&lt;/a&gt; &lt;/div&gt;   When user clicks a link from above HTML, I want to get the jQuery object of the corresponding &lt;a&gt; element, and then manipulate its sibling. I can't think of any way other than creating an ID for each &lt;a&gt; element, and passing that ID to an onclick event handler. I really don't want to use IDs.   Any suggestions?

I know that I can check from where one particular package would be called, using  kpsewhich &lt;packagename&gt;.sty   and that if I want a custom package, I usually have to put it in the same folder as my document.   I assume that similar to a $PATH, LaTeX checks a list of paths in an attempt to find my package.   Which paths are those? In what order are they checked? If this is system-specific, how can I find out the configuration for my system?   Related questions:    , the answers to which contain some paths that  LaTeX apparently checks.  mentions    &gt;    /usr/local/texlive/2009/texmf &gt;    /usr/local/texlive/2009/texmf-dist &gt;    /usr/local/texlive/texmf-local &gt; &gt; as well as other directories.

Totally disconnected space that is not $T_2$ How to automatically install entire Google Web Fonts collection? Evolution threads extra lines before signature What exactly is a photon? Why not make it mandatory to leave a reason or at least a remark of some sort whenever down voting?  You see more and more often questions being down voted while many times they are simply perfectly legitimate, as questions/as people being unable to achieve some desirable result. I am not talking about "Hey, please do this and that for me, thanks :D " posts.  I would like to know what reasons there are for not making it mandatory to leave a reason for a down vote. Math mode in tabular without having to use $...$ everywhere How to correctly use the present perfect tense This  states that:  When you use the present perfect tense you have to be talking about a period of time that you still consider to be going on. For example, if it’s still morning, you can say, &quot;I’ve shaved this morning.&quot; If it is afternoon or evening, all of a sudden &quot;I’ve shaved this morning&quot; sounds really weird.  &quot;I've shaved this morning&quot; sounds more like past perfect, and indication of specific time (in the morning) makes this sentence incorrect.  Am  I spot on? Then what is the difference between the construct of past perfect, present perfect and future perfect?
