Floats appearing in wrong places Which tools and technologies are used to build the Stack Exchange Network? show elements of order 15 in $S_8$ satisfy a relation Let $G$ be a group.  Define a relation $\sim$ on $G$ by $a \sim b$ if there exists $g \in G$ such that $a = gbg^{-1}$.  Prove that all elements of order 15 in $S_8$ are related by $\sim$.  I noticed that in order to have order $15$ in $S_8$. We need a $5$ cycle and a $3$ cycle. Then, I am stuck. Can anyone give me some ideas about what to do? Thank you in advance.

Declaring Text Decorations such as Underline, Strikethrough in a Style How do I include text decorations such as Underline, Strikethrough etc in a Style definition:  &lt;Style x:Key="UnderlinedLabel"&gt;      &lt;Setter Property="Control.FontFamily" Value="Trebuchet MS" /&gt;      &lt;Setter Property="Control.FontSize" Value="14" /&gt;      &lt;!-- Next line fails --&gt;      &lt;Setter Property="Control.TextDecorations" Value="Underline" /&gt; &lt;/Style&gt;   I'm familiar with using the following XAML to underline text:  &lt;TextBlock&gt;    &lt;Underline&gt;        Underlined text    &lt;/Underline&gt; &lt;/TextBlock&gt;   However text decoration is just another style, I want to be able to define it declaritively like FontWeight, FontSize etc.  [Update]  I was applying this style to a Label control.  This was my main problem.  It appears you can't underline text in a Label.  Change to a TextBlock (thanks gix) and all is well. How to monitor process/program execution in windows? We are trying to develop a small application that can monitor the programs/processes that are executing in a windows machine.  If the program/process is not supposed to run, it should be blocked. It works similar to an antivirus.  This is the basic idea.  I want to know the ways to hook into the OS to get notified about every single program/process trying to run in the machine. How to install software or upgrade from an old unsupported release? How do you differentiate the likelihood function for the uniform distribution in finding the M.L.E.? There is a classic problem:  Suppose that $X_1,\ldots,X_n$ form an i.i.d. sample from a uniform distribution on the interval $(0,\theta)$, where $\theta&gt;0$ is unknown. I would like to find the MLE of $\theta$.  The pdf of each observation will have the form: $$ f(x\mid\theta) =  \begin{cases} 1/\theta\quad&amp;\text{for }\, 0\leq x\leq \theta\\ 0 &amp;\text{otherwise}. \end{cases} $$ The likelihood function therefore has the form: $$ L(\theta) = \begin{cases} 1/\theta^n \quad&amp;\text{for }\; 0\leq x_i \leq \theta\;\; \text{for all }i,\\ 0 &amp;\text{otherwise}. \end{cases} $$ The general solution is usually that the MLE of theta must be a value of $\theta$ for which $\theta \geq x_i$ and which maximizes $1/\theta^n$ among all such values.   The reasoning is that since $1/\theta^n$ is a decreasing function of $\theta$, the estimate will be the smallest possible value of $\theta$ such that $\theta\geq x_i$.  Therefore, the mle of $\theta$, $\hat{\theta}$, is $\max(X_1,\ldots,X_n)$.  Here, I do not understand why we cannot just differentiate the likelihood function with respect to theta and then set it equal to $0$?  Thanks! Should I follow what was mentioned in the “duration of stay” or in the "validity of the visa"? I'm from Tunisia and I got a Schengen visa from the Austrian Embassy for  28 days, the “duration of stay”, and the number of entries is 1. But the validity of the visa is from 02/08/2015 to 13/09/2015.  Do I have to stay only 28 days, for example from 02/08/2015 to 29/08/2015 or can I stay there until 12/09/2015 ?  And if I have got to stay only 28 days, then can I choose the days of stay, that's mean can I stay in Austria for example from 09/08/2015 to 05/09/2015? I just need to check the reasoning in my proof is correct, I think it is valid although I'm not totally convinced because I can't follow the logic; does proving that $x$ is an integer prove that $ac|bd$?  Theorem: Let $a$, $b$, $c$, $d$ be integers. If $a|b$ and $c|d$, then $ac|bd$.  Proof: $aj=b$ and $ck=d$ for integers $j$, $k$. Then, $ac|bd$ implies $acx=ajck$ and thus $x=jk$ for some $x$. Since the product $jk$ is an integer, $x$ is an integer and thus $acx=ajck$ and thus $ac|bd$. Distribution of the digits of Pi How to print the full NumPy array, without truncation? How to use getElementsByClassName in javascript-function? Should I format /sdcard and /data if I want to wipe all personal data with Cyanogenmod? I'm trying to completely wipe all personal data from my Nexus 4 with CM installed. I've seen different advice on different sites for making sure all my data is gone:   Just do 'Factory Reset'. Do 'Factory Reset' at least 3 times. Do 'Factory Reset' and wipe dalvik cache. ...   and so on... I'm interested in erasing all traces of my personal data from the device. It's a Nexus 4, so there is no removable storage to worry about.  My guess would be to 'wipe data/factory reset' and 'wipe cache partition' in the main recovery menu. In the mount/storage menu, I would choose 'format /cache', 'format /data', and 'format /data and /data/media (/sdcard)'. Finally, in the advanced menu, I would choose 'wipe dalvik cache'.   Is this thorough enough? Should I also choose 'format /system', 'format /firmware', etc? Are there any options I should steer clear from? I would like the phone to boot to a fresh Cyanogenmod after clearing all data.

Now, using inotify is simple, you just need to know the directory you want to get notifications from.  How do I retrieve a module's path in python? Find the expected value of $\frac{1}{X+1}$ where $X$ is binomial The problem:  X is a binomial random variable, find $E[\frac{1}{X+1}]$ n and p are not given  PDF for a binomial distribution is $\binom{n}{k}p^k(1-p)^{n-k}$  Expected value is $\sum{x_ip(x_i)}$  But this is where I get stuck, I'm really rusty on my statistics and I'm not sure exactly how to structure it in the next step? I think I want to get the form of the following out of the summation  $\sum _{k=0}^{n} \binom{n}{k}p^k(1-p)^{n-k} = (p + 1 - p)^n = 1$  But I'm not sure if it should look like  $\sum \frac{1}{xp(x)+1} $  and if it should where to go from here? Make terminal use pageup/pagedown instead of shift-pageup/shift-pagedown? I've grown quite weary of shift-pgup to page up in gnome terminal, the command line, terminator, and guake, etc.  Any way to easily make these apps use the straight page-up and page-down keys for paging around? I'm on the hunt for a great sounding, non-in-ear set of headphones with working mic, play/pause, and volume buttons.  I have Bang &amp; Olufsen's , which are among the best sounding headphones I've ever used. And all three button work perfectly in my MacBook Air and iPhone.  Obviously they don't work perfectly in my Nexus 4, since Android devices uses a different way of reading volume up/down buttons.  So, my question is rather simple, does anyone know how to make them work with Android, or alternatively any equally good headphones to the EarSet 3i's that work on Android? And to make it extra challenging, no in-ear ones please, cause I can't stand them :(  Or maybe anyone knows of some kind of adapter cable that can be used between an Android phone and iPhone compatible headphones to translate the volume button signals so the Android device understands them? How do I know if I'm working on a Virtual Machine or not? Is there a way to know if the Windows machine I'm working on is virtual or physical? (I'm connecting with RDP to the machine. If it's a virtual machine it is working and handled by VMWare).
