Flexslider view preview working but not on actual page My block is not working for the flexslider: The images are not appearing, but the view preview does work.  I don't know if it is relevant, but a similar problem would happen with just a slideshow view, although one image would appear and it would not cycle.  Could jQuery be a problem?  The following is the actual page with the block that is not showing any images.        The following is the view preview, which works. How do I use RSolve to solve a system of recurrence relations? On the functional square root of $x^2+1$ There are some math quizzes like: find a function $\phi:\mathbb{R}\rightarrow\mathbb{R}$  such that $\phi(\phi(x)) = f(x) \equiv x^2 + 1.$  If such $\phi$ exists (it does in this example), $\phi$ can be viewed as a "square root" of $f$ in the sense of function composition because $\phi\circ\phi = f$.  Is there a general theory on the mathematical properties of this kind of square roots? (For instance, for what $f$ will a real analytic $\phi$ exist?) Mail.app crashes constantly, even after deleting mail profile and cache Can we make a Vpn server run on Android. Can applications do this? If yes, which protocols are supported and is this a good idea to use such apps? If not, what are some issues that we may face? A little background:  I do not know what the specifics are, but I've noticed that a quick edit after a post will often times not result in an edit being posted. It's as if there was no edit. Edit: According to Bart this amount of time is five minutes.  The problem:  A user made a really bad post (said that ~ in C# wrt integers was used for deconstruction). I down-voted said post. Post quickly disappeared (I guess poster realized they screwed up and took back the post). Later, I come back and see my down vote but the answer is now correct (that ~ is the bitwise complement operator). I try to get rid of my down vote because it is no longer appropriate. However, it has been about half an hour and there is no edit posted (presumably the poster made an edit within the non-posting edit window) so I can't take my vote back.  Suggested solution:  If post gets edited (even within the non-post edit window) mark all the votes as changeable. I would guess that this would either involve an update on a table of votes or adding a column for last edit time which is not bypassed by the grace period. I realize that this may be an entirely non-trivial change, but unless the non-posting of edits is somehow changed to make sure the edit was trivial it seems this is necessary. Do particles ever touch each other during a collision? While reading a book, I came across the word I'd've, as in:     I'd've argued against it.   While it was obvious what it meant, it left me puzzled. Is I'd've a proper word? Is it possible in Minecraft to switch over from survival to creative in single player? When closing a question as duplicate the &quot;Possible duplicate of&quot; comment is automagically added to the question. However when adding such a comment manually: &quot;possible duplicate of random text&quot; that comment is also removed. To me it doesn't make sense that questions which to not point to a SO / SE question or even comments without any links in it are also removed when the question is closed as a dupe. I just found this out by close voting a question as a dupe of another question, but I also added a manual comment which linked to a user profile (because it contains lots of relevant information for OP and possible future reasons): possible duplicate of this [user](http://stackoverflow.com/users/727208/teresko?tab=answers&amp;sort=votes)'s list.  By the looks of it the script simply checks whether the comment starts with &quot;possible duplicate of&quot; and if it matches it will be removed. The  team also did a quick test with a very simple example which also got thrown away: possible duplicate of testing........  I understand that this issue is minor and there might as well be a technical reason for this (i.e. not having to keep track of automatic vs manual comments), but this behavior is kinda odd to me. I can think of two solutions for this:  keep track of manually vs automagically added dupe comments (again you SO people might have a good reason to not want this). Improve the &quot;dupe comment matcher ™&quot; to at least check whether the comment is in the correct format for &quot;auto dupe comments ™&quot; with a proper link to a question page. Empty intersection and empty union If $A_\alpha$ are subsets of a set $S$ then   $\bigcup_{\alpha \in I}A_\alpha$ = "all $x \in S$ so that $x$ is in at least one $A_\alpha$"  $\bigcap_{\alpha \in I} A_\alpha$ = "all $x \in S$ so that $x$ is in all $A_\alpha$"  It is the convention that $\bigcup_{\alpha \in \emptyset}A_\alpha = \emptyset$ and $\bigcap_{\alpha \in \emptyset} A_\alpha = S$.   But if $x$ is in $\bigcap_{\alpha \in \emptyset} A_\alpha = S$ then $x$ is in all $A_\alpha$ with $\alpha \in \emptyset$ and therefore $x$ is certainly in at least one $A_\alpha$ with $\alpha  \in \emptyset$. But then $x \in \bigcup_{\alpha \in I}A_\alpha$.  Can someone help me and tell me what is wrong with this? Thank you.

By default blender allows you to scale past 0 - how do I prevent this?  i.e. it's common in other 3D modelling software to resize a set of vertices against an axis to align them - however this isn't possible when negative scaling is enabled. How to change boot priority? I have a laptop with Ubuntu installed as the only OS. I also have a USB stick with a Windows 7 installation on it. I want to install Windows from the USB stick on my laptop but when I try to restart the laptop to get access to BIOS, I can't seem to find the command for it, its like it skips everything and just says Ubuntu and then takes me to the login screen.  How do I change the boot priority to USB in Ubuntu? Comma with 'who' in this specific sentence Can you shed light into this?  The coach came to the defence of the player who has been sacked from the team following his differences with the captain.  OR  The coach came to the defence of the player, who has been sacked from the team following his differences with the captain.  Isn't the subordinate clause that begins with 'who', non-restrictive? The dialog box in question here is the one you get with the context menu option "open with other applications". Wine seems to have inserted more than a dozen or so entries for each application I install, which makes it a pain to find the correct application:     What can I do to remove the duplicates?     Update: Neither of the two solutions really work. The bug is interesting, but the symptoms does not match my problem (I'm not having problem with uninstalling applications, but rather the things that are inserted after installing them), and with the other one, all references to the Wine application are removed, which actually makes the problem worse (although it may be an acceptable solution if nothing else can be found). So this is still an open question; any takers? Let $X\subset \mathbb{R}$ Lebesgue measurable, $|X|<|\mathbb{R}|$, is it true that $X$ is null? Creating square buffer around point feature using ArcGIS for Desktop? I would like to create a square buffer from a point feature but I do not understand the code that goes into it.   Similar questions have been asked on the forums.esri website but that was over 10 years ago, and it did not work when I tried the code.  How do I create a square buffer from a point feature?
