Where can you ask about Career Advice? The  specifically says not to ask  for career advice but people do it anyway.  Should I consider the Help Center outdated or only loosely enforced?    And what about a career advice site on the network?  There are 70+ sites, and most of them are for relatively narrow interests (which is not a criticism, I enjoy looking through the many sections).  A career section seems like it would be very popular.  Also, a careers section would help keep career questions off the other sites. In my calculator why does $\sqrt4 -2=-8.1648465955514287168521180122928e-39?$ I have tried this on my Windows 7 calculator with $\sqrt9 -3 $ it too gives some weird answer- ie$1.1546388020691628168216106791278e-37$. And so for any $n$(positive) $\sqrt n^2-n= wierd_ .answer$ Why does this happen? What's wrong with XKCD's Frequentists vs. Bayesians comic? makes fun of a frequentist statistician who derives an obviously wrong result.  However it seems to me that his reasoning is actually correct in the sense that it follows  the standard frequentist methodology.   So my question is "does he correctly apply the frequentist methodology?"    If no: what would be a correct frequentist inference in this scenario? How to integrate "prior knowledge" about the sun stability in the frequentist methodology? If yes: wtf? ;-) Let $X$ be a normed linear space, $x\in X$ and $r&gt;0$. Define the open and closed ball centered at $x$ as  $$ B(x, r) = \{y \in X : \Vert x − y\Vert &lt; r\} $$  $$ \overline{B}(x, r) = \{y \in X : \Vert x − y\Vert \leq r\}. $$ Then $B(x, r)$ and $\overline{B}(x, r)$ are convex.  I tried to prove this, but either my calculation is incorrect, or I am on the wrong path:  I aim to show for the closed ball $\overline{B}(x,r)$ (for open ball I assume the proof is similar). Suppose $y,z \in \overline{B}(x, r)$. Then $\Vert x − y\Vert \leq r$ and $\Vert x − z\Vert \leq r$. We must show that $t \in [0,1]$ implies $ty + (1-t)z \in \overline{B}(x,r)$. But $t \in [0,1]$ implies $$ \Vert ty + (1-t)z - x\Vert = \Vert t(y-z) + z - x\Vert \leq |t| \Vert y-z\Vert + \Vert z-x\Vert \leq |t|(\Vert y-x\Vert + \Vert x-z\Vert) + \Vert z-x\Vert &lt; |t|(2r) + r = r(2|t| + 1), $$ which is not necessarily $\leq r$. We probably wanted to end up with $&lt; |t|r$ or $\leq |t|r$ as our final inequality.  Thanks in advance. Is there any shortcut/easy way to switch this system proxy settings? Prove if $|a_{n+1}|/|a_n| \leq |b_{n+1}|/|{b_n}|$ and $\sum |b_n|$ is convergent, then $\sum |a_n|$ is convergent Allow bounty to be set with reputation from another site? Here's one to get shot down: How about letting bounties to be set using the reputation gained through the use of another site? So, for instance, I'm a programmer with a high Stack Overflow rep who hates using computers. Wouldn't it be useful for me to be able to exchange some of my excess Stack Overflow credit to incentivise a question on Super User?   Or perhaps I'd like to highlight a question on Meta Stack Overflow, but I don't spend my time there. Show that, in any finite graph with at least two vertices, there must be two vertices with the same degree.  HINTS ONLY! Heartbleed: are services other than HTTPS affected? The OpenSSL 'heartbleed' vulnerability () affects webservers serving HTTPS. Other services also use OpenSSL. Are these services also vulnerable to heartbleed-like data leakage?  I'm thinking in particular of   sshd secure SMTP, IMAP etc -- dovecot, exim &amp; postfix VPN servers -- openvpn and friends   all of which, on my systems at least, are linked to the OpenSSL libraries.

I am trying to test the output of a controller that returns some information in a given page. This controller has a custom http client injected into it.  I want to create a BrowserTest that can navigate to a fake node, and then test for certain text or values. I also want to change the mock to return different values, so I can further test the output to account for those cases.  I tried:      $client = $this-&gt;getMockBuilder('\Drupal\mymodule\Client\AuthorizeClient')       -&gt;disableOriginalConstructor()       -&gt;getMock();     $client-&gt;expects($this-&gt;any())       -&gt;method('request')       -&gt;with('w12345', FALSE)       -&gt;willReturn([]);      $this-&gt;container-&gt;set('mymodule.auth_client', $client);   But I get errors in the test that refer to the original class, and not the one I am trying to replace. I looked around in the core but wasn't really able to find what I was looking for. Does it make sense to do this? Is there a way to do a Kernel test to test responses from the route in question? I'm trying to load data from different tables using left outer joins into a QgsVectorLayer. The approach I'm following so far is the one from the developers cookbook . The underlying database is postgres. The query returns correct data, including a geometry column, however I can't figure out how to get the join inside the query to work with . As the table the data come from needs to be specified, is it even possible to do so?  Would approaching the problem using psycopg2 be more suited, and if so, is there a way to create a layer from the result set? The only way I can think of is creating an empty layer and adding each feature individually by looping over the result set. But possibly there is an easier way?  Sadly, using the builtin DB Manager is not an option. The layer has to be added programmatically. Why do people go to the Wall in Game of Thrones? Is the wall a bad or a good place to be? Some people are sent there as punishment, others go because they want to (Jon Snow), others to get away from harm (Arya).  If I am not completely correct, it is because I have only started watching the series recently, and it is a bit confusing!  Please also correct me if I am wrong with any facts! I am trying to solve the following exercise.      Assume that $m$ and $n$ are co-prime positive integers, and that $k$ is a field. Prove that the ideal generated by $x^{m} - {y^n}$ is a prime ideal in $k[x,y]$.   I tried the following approach : Consider the ring homomorphism ${\varphi}:k[x,y]\rightarrow{k[t]}$ defined by $\varphi(x) = t^n$, and $\varphi(y) = t^m$, and extend $\varphi$ to $k[x,y]$ to ensure that it is a ring homomorphism. Then the ideal $(x^m - y^n)$ is clearly contained in the kernel of $\varphi$. It remains to prove the reverse set inclusion. i.e. to prove that this ideal is exactly equal to the kernel of $\varphi$. I don't know how to go about this! How to stop constantly blinking Wifi LED? When should I use "a" versus "an" in front of a word beginning with the letter h? Can't find the reason why root directory usage is so large I'm trying to find an alternative to the standard tombstone qed symbol for more informal papers. I initially thought of an empty square with Pub written inside, but what would actually be better would be a small beer mug symbol. (much like the one found in this set of icons )  Unfortunately there doesn't seem to such a symbol in the comprehensive latex symbol list (although many funny symbols can be found there). Has anyone thought about this? Is there any quick-and-dirty solution?
