When will data.SE get updated data? If $2^p-1$ is a prime, (thus $p$ is a prime, too) then $p\mid 2^p-2=\phi(2^p-1).$  But I find $n\mid \phi(2^n-1)$ is always hold, no matter what $n$ is. Such as $4\mid \phi(2^4-1)=8.$  If we denote $a_n=\dfrac{\phi(2^n-1)}{n}$, then $a_n$ is , but how to prove it is always integer?  Thanks in advance! Are orbiting planets an  example of perpetual motion? WCF server-side timeout I am always confused about where to put adverbs in sentences. For example, consider the questions below:        Why did they target us specifically?   Why did they target specifically us?   Why did they specifically target us?      I believe all these sentences mean the same. Am I correct? I am always confused about where to put adverbs such as always and specifically, etc. Is there a particular grammar rule for this?  Funny, you see, I can even form the above sentence in different ways.         I always confuse where to put this kind of adverb   Always I confuse where to put this kind of adverb When and where do I have the highest chance of seeing auroras? I'm wondering what time of year is best, and what locations might be best, for catching the aurora.  I'm currently thinking of February up at Sweden's ice hotel, but since the whole point of the trip is so that my wife can see the Aurora, I want to pick a location that affords the best chances to see one.  Edit: Just adding a link so you can see realtime aurora activity in the northern hemisphere    I know this is anecdotal, but I ended up going to Iceland in late february during the new moon and saw the aurora 3 out of 6 nights I was there.  There was activity every single night but the biggest problem was weather.  It was cloudy almost every single night. How do I use sudo to redirect output to a location I don't have permission to write to? Why shouldn't I care what model/make/year my bicycle is? Taxonomy count per Post type Below is the code i use to output the post tag (taxonomy) count/number. I want to be able to split the count based on post type that the taxonomy features in (rather than the total number).   So i have the default "post" Post type, aswell as "blogs", &amp; "pics". I want the taxonomy count to display something like: x posts | x blogs | x Pics              &lt;?php             $tags = get_tags( array('name__like' =&gt; "a", 'order' =&gt; 'ASC') );             foreach ( (array) $tags as $tag ) { ?&gt;                 &lt;li&gt;                                                 &lt;a href="&lt;?php echo get_tag_link( $tag-&gt;term_id ) ?&gt;"&gt;                                   &lt;span class="name"&gt;&lt;?php echo $tag-&gt;name ?&gt;&lt;/span&gt;                         &lt;span class="number"&gt;&lt;?php echo $tag-&gt;count ?&gt;&lt;/span&gt;                     &lt;/a&gt;                 &lt;/li&gt;             &lt;?php } ?&gt; Left inverse implies right inverse in a finite ring Let $R$ be a finite ring with identity $1$, and assume $\exists x,y\in R$ such that $ xy=1$. How can I show it implies $yx=1$? I generally defrost meat on the kitchen counter. A friend of mine suggested that this was dangerous and suggested that I defrost meat in the refrigerator. I am no biologist but it seems to me that as long as the meat doesn't get warm defrosting it on the counter should be safe.  Generally, I remove the frozen items from the freezer and place them on a plate on the counter in the packaging they were frozen in. When they are mostly / completely thawed I place the meat in the refrigerator.  Am I wrong and should I be defrosting in the refrigerator? I am trying to prove the following:  In $C[0,1]$ the functions that preserve the rationals (i.e. $f(\mathbb{Q})\subseteq \mathbb{Q}$) are dense.  So far, I have not made much progress- I am aware that $A$ is dense in $B$ iff $A$ has non-empty intersection with each open set $U$ in $B$ but am not sure how to apply this definition. I have also thought about showing that the closure of $X$ (where $X$ is the set of functions that preserve the rationals) is equal to $C[0,1]$ by a double-inclusion proof but I have also made no progress with this approach. Am I on the right track or should I change my approach? I am trying to understand how to find the orthogonal complement of a subspace $M$ of a vector space $V$.   From my understanding, $M^\perp$ is also a subspace of $V$ where all its vectors are perpendicular (orthogonal) to the columns of $M$, which would mean that the dot product of those vectors with each column of $M$ is $0$.  However, how do I find the $M^\perp$ subspace, when $M = \{ \vec{x} \in \mathbb{R}:  2x_2 + 3x_1 = 0\}$? In general, if there's a general approach, how does one attempt to find $M^\perp$ of an arbitrary $M$?  From my understanding, in this case, $M$ is the set of vectors in a plane that satisfy that equation, where $x_1$ and $x_2$ should respectively be the first and second components of the vector $\vec{x}$. Can unconscious characters be willing? This situation came up last week during our session. The party was facing a pretty difficult mob of enemies and one of the party members was knocked unconscious. Seeing the situation worsening, one of the players decided to use the  (DMG p. 197). In the text, it says:     The rod then instantly transports you and up to 199 other willing creatures you can see to a paradise that exists in an extraplanar space.   At first glance I thought this was actually a pretty good time to use the rod. The question came up though, what about the party member who is unconscious? In the end I made the call that the character went with them to keep things moving and more fun.  However, I'm feeling like back pedaling a bit and notifying my players that for future uses, the line "... willing creatures..." will be more strictly enforced as I don't feel like an unconscious creature could be willing.  Did I handle this the right way? Two of my friends are getting married. They're both huge Doctor Who geeks, and actually met through a DW RPG. Their wedding invitation contained a very subtle DW reference (you wouldn't have been able to tell unless you were very familiar with the show yourself.)   Doctor Who's been running long enough that there are quite a few nice quotes for basically every occasion in life. I was hoping someone would know a nice wedding-related one, or maybe one about love, that I could include in a wedding card? How do I put text over symbols? I've been writing C and C++ code for almost twenty years, but there's one aspect of these languages that I've never really understood. I've obviously used regular casts i.e.  MyClass *m = (MyClass *)ptr;   all over the place, but there seem to be two other types of casts, and I don't know the difference. What's the difference between the following lines of code?  MyClass *m = (MyClass *)ptr; MyClass *m = static_cast&lt;MyClass *&gt;(ptr); MyClass *m = dynamic_cast&lt;MyClass *&gt;(ptr); How did Montague Apparate into the Hogwarts bathroom?
