I'm having a bit of trouble thinking of a good way to describe/search for this, so bear with me if it's a duplicate.  I recently realised that in the iOS app, when you click a link and a page is opened in the included browser, apart from closing the browser by hitting the “OK” button at the top (which is not always visible), swiping from left to right to ‘go back’ has the same effect.  However, when I close the browser in this manner, the question that I return to remains frozen for about five seconds, and even after it unfreezes, the “&lt;” button to return to the previous question or question list does not work. It looks normal, but when I click on it, it changes to being greyed out and does nothing.  If I close the browser with the “OK” button, this does not happen: the question does not freeze, and the “&lt;” button works as it should.  Is this a known bug?  (iOS 9.2.1, up to date; SE app version 1.4.3.7.)
iOS app 1.4.3, iOS 9.2.1  While viewing a post, the app somehow ended up in a state where it refuses to do much of anything.  What does work:   Swipe-scrolling vertically Jumping to the previous / next post using the up / down buttons    Everything else, though, has no effect:   Swipe-scrolling horizontally will not return to the previous view Tapping on a code block will not zoom to code-block view Tapping Delete button to delete a post will show a confirmation dialog, but saying yes will not cause deletion The Add Comment button brings up the text field, but I cannot type anything in it; I can only dismiss it None of the other buttons (Share, More, etc.) do anything Cannot view user profiles or revision history Tapping on links in a post or comment will not show a web page Tapping on a tag shows some visual feedback with a temporary color change, but doesn't do anything else   I still receive push notifications, but tapping on them doesn't take me anywhere.

Bender often pulls large objects from his torso cupboard, but how deep or how much empty space is he capable of storing? Can he bend space around the perimeters of the frame of his torso's door? If that is the case, does it also bend time? I suppose he might bend in more ways than one... Why doesn't the Moon fall onto the Earth? Why doesn't the Moon fall onto the Earth?

Let $(X,d)$ and $(Y,\rho)$ be metric spaces and $f:X\to Y$ be a function and suppose for any Cauchy sequence $(a_n)$ in $X$, $(f(a_n))$ is a Cauchy sequence in $Y$.  Is $f$ continuous?  Let $f$ be continuous, is it uniformly continuous? How do I place a bootable ISO on a USB drive? Question: Are there infinitely many primes of the form $4n+3$ and $4n+1$?  My attempt: Suppose the contrary that there exist finitely many primes of the form $4n+3$, say $k+1$ of them: $3,p_1,p_2,....,p_k$  Consider $N = 4p_1p_2p_3...p_k+3$, $N$ cannot be a prime of this form. So suppose that $N$=$q_1...q_r$, where $q_i∈P$  Claim: At least one of the $q_i$'s is of the form $4n+3$:  Proof for my claim: $N$ is odd $\Rightarrow q_1,...,q_r$ are odd $\Rightarrow q_i \equiv 1\ (\text{mod }4)$ or $q_i ≡ 3\ (\text{mod }4)$  If all $q_1,...q_r$ are of the form $4n+1$, then $(4n+1)(4m+1)=16nm+4n+4m+1 = 4(\cdots) +1$  Therefore, $N=q_1...q_r = 4m+1$. But $N=4p_1..p_k+3$, i.e. $N≡3\ (\text{mod }4)$, $N$ is congruent to $1\ \text{mod }4$ which is a contradiction.  Therefore, at least one of $q_i \equiv 3\ (\text{mod }4)$. Suppose $q_j\equiv 3\ (\text{mod }4)$  $\Rightarrow$ $q_j=p_i$ for some $1\leq i \leq k$ or $q_j =3$  If $q_j=p_i≠3$ then $q_j$ | $N = 4p_1...p_k + 3 \Rightarrow q_j=3$ Contradiction!  If $q_j=3$ ($\neq p_i$, $1\leq i \leq k$) then $q_j | N = 4 p_1...p_k + 3 \Rightarrow q_j=p_t$ for some $1 \leq i \leq k$ Contradiction!  In fact, there must be also infinitely many primes of the form $4n+1$ (according to my search), but the above method does not work for its proof. I could not understand why it does not work. Could you please show me?  Regards Upgrade to version newer than repositories I have  about how to upgrade ghostscript to a version that is available on 15.04 but not on 14.04LTS (which I have). On this site there are numerous almost identical question regarding different packages, a few examples include:         So I thought it would be very useful in general to know: is there  a general, automated way to upgrade a package, including all its dependencies, to a version that is newer than Ubuntu's repos? Is this more easily done if the newer version exists in more recent Ubuntu releases? I asked  yesterday, approximately 18 hours ago ("2011-12-13 20:24:03Z" according to the hover text), and it's still being displayed as "today".  I assume the "Z" in the timestamp refers to Zulu time, so I , and the date (2011-12-14) differs from the timestamp on the question.  I don't pretend to understand all of the complexities when converting time zones, but I thought it was strange enough to report. If it matters at all, I'm in US-Eastern. I have two disks in my system:   Non-UEFI windows 10 install UEFI kubuntu 16.10   This system is my home server. I'm migrating from Windows to Kubuntu, but it will take a while since I can't yet duplicate the entire functionality. In the mean time I want to run dual boot so that I can run the server as was (windows) while I'm setting up the Kubuntu deploy in any spare time I get. So:  I'd like to add windows boot to grub's target list, however update-grub does not find my Windows bootloader.  I'm guessing the problem is that it's searching for an EFI boot while there is only a legacy BIOS one.  Is there a way I can add my Windows install as a grub target? If I utilize the two columns of multicols for my Kurdish sequence of numbers, it arranges the items in column like the following figure:   But I want to arrange the items in rows splitted by some columns (two columns in this case) alike the following figure:   And for the case of "three columns", the output would be alike the following figure:   How may I achieve the functionality? And I don't want to use the sequence of the following commands:  \begin{multicols}{2}‎ \begin{enumerate}[$1)$,noitemsep] \item ‎ Yek \item ‎ Du \end{enumerate} \end{multicols}‎   Instead, I want to specify the split count of the columns and then have the items arranged in the desired arrangement automatically.

MySQL strip non-numeric characters to compare creating a diagonal matrix with a variable amount of parameters Indecomposable limit ordinals A limit ordinal $\gamma&gt;0$ is said to be indecomposable iff $\nexists\alpha,\beta&lt;\gamma$ such that $\alpha+\beta=\gamma$.  In view of this definition, I’m trying to prove the equivalence of the following statements for limit ordinals $\gamma$:  (1) $\gamma$ is indecomposable.  (2) $\alpha+\gamma=\gamma$ $\forall\alpha&lt;\gamma$.  (3) $\gamma=\omega^\alpha$ for some $\alpha\in\mathrm{ON}$.  I’ve been able to get $(1)\implies(2)$ and $(3)\implies(1)$, but I have nothing more than scratch work for $(2)\implies(3)$.  Any suggestions would be appreciated.

Predicator vs. Predicate BACKGROUND According to Oxford Dictionaries Online:   means &quot;(In systemic grammar) a verb phrase considered as a constituent of clause structure, along with subject, object, and adjunct.&quot;  means &quot;The part of a sentence or clause containing a verb and stating something about the subject (e.g. went home in John went home).&quot;  In the latter example of John went home, it seems, the predicate is went home whereas the predicator is went, home being an adjunct and thus not part of the predicator as defined. Now, I looked further in  to better understand the difference. The article recognizes two competing notions of the predicate in theories of grammar:  (1) Predicates in traditional grammar (e.g., went home in John went home) (2) Predicates in modern theories of syntax and grammar (e.g., went in John went home)  Which, according to the article, causes confusion as to what exactly the term predicate mean, and some grammarians came up with a new term &quot;predicator&quot; specifically for use (2), says the article. No problem thus far. What bothers me: The article in its explanation of (2) says, &quot;Other function words -- e.g. auxiliary verbs, certain prepositions, phrasal particles, etc. -- are viewed as part of the predicate.&quot; (Emphasis mine.) Now, remember this definition of the predicate, i.e., (2) above, corresponds to the new term &quot;predicator&quot;. I understand that auxiliary verbs are part of this definition of predicate, because an auxiliary verb can be part of a verb cluster. But can certain prepositions and phrasal particles also? The article has these example sentences (Words belonging to &quot;predicate&quot; (2) are boldfaced as in the article itself; My comments in parentheses.):  The butter is in the drawer. (preposition in being part of the predicate) You should give it up. (particle up being part of the predicate) Susan is pulling your leg. (I don't know why leg is marked as part of the predicate. Maybe a typo?)  QUESTION Except for the last one, which I suspect is a typo, I'd like to know whether the preposition in and the particle up belong to the predicate as presented in (2) and thus belong to the new term &quot;predicator&quot;. Per the title, does $\displaystyle\sum_{n=1}^{\infty} \sin(\pi(2+\sqrt{3})^n)$ converge? Converge absolutely?   I'm stuck on this question, not sure how to approach it.  Thank you!

How to call a space in which every G$_\kappa$-set is open Recall that in a topological space $X$, we say that a subset $A\subset X$ is a G$_\delta$-set if $A$ is the intersection of countably many open sets of $X$. Also, we say that $X$ is a  if G$_\delta$-sets are open.  Now, call as G$_\kappa$-set the intersection of $\kappa$ many open sets, where $\kappa\geq\aleph_0$ is a cardinal. I would like to know if there is some standard name for those spaces in which G$_\kappa$-sets are open, for a fixed cardinal $\kappa\geq \aleph_0.$  Motivation: this kind of space arose in my PhD thesis, but I do not know any references in which they appear. I'm temporary calling them as $P_\kappa$-spaces. Getting tabular statistics from table using QGIS? Are there QGIS tools that will allow users to get tabular statistics from their table?  I kind of expected I would be able to just open the table, select the field I was interested in, right-click on the field header and get something similar to this (screenshot taken from ArcGIS):    More specifically, I am looking for a QGIS alternative to the ArcGIS  and  tools, that offer a  you can retrieve about the tabular data.    Just after asking, I found  (see section 4.2 ) that describes how to find this functionality... Vector > Analysis Tools > Basic statistics.  I also found Vector > Analysis Tools > List Unique Values right next to it.  This gets me the list of unique values, but I would also like to see an additional column of frequency (count) of each unique item.  Is this similar tool available "out-of-the-box"?
