I have a JS file exporting an array of objects. Each object contains a property with a URL strings. Here's an example: export const data = [   {     name: 'aaa',     content: '&lt;a href=&quot;someurl&quot; title=&quot;&quot;&gt;Click here&lt;/a&gt; or &lt;a href=&quot;otherurl&quot; title=&quot;other url&quot;&gt;here&lt;/a&gt;'   },     {     name: 'bbb',     content: '&lt;a href=&quot;additional&quot; title=&quot;some title here&quot;&gt;Click here&lt;/a&gt; or &lt;a href=&quot;anotherurl&quot; title=&quot;&quot;&gt;here&lt;/a&gt;'   } ]  Notice the title property on each link, which may be empty or include some text. In my IDE (Webstorm) I want to search for every occurence of title, including the double quotes and the text between them or with empty double quotes. Essentially I want to be able to find each occurence of title=&quot;some text&quot; and title=&quot;&quot;. Webstorm support searching with RegEx, but I have to idea how to construct such expression. I tried title=[&quot;]\D[&quot;], title=[&quot;]\w\s[&quot;], [&quot;][a-zA-Z][&quot;] and a few more... None of them worked. Any ideas how to construct such RegEx?
I have a txt file which actually is a html source of some webpage. Inside that txt file there are various strings preceded by a "title=" tag.  e.g.   &lt;div id='UWTDivDomains_5_6_2_2'  title='Connectivity Framework'&gt;    I am interested in getting the text Connectivity Framework to be extraced and written to a separate file.  Like this, there are many such tags each having a different text after the title='some text here which i need to extract '  I want to extract all such instances of the text from the html source/txt file and write to a separate txt file. The text can contain lower case, upper case letters and number only. The length of each text string(in characters) will vary.  I am using PowerGrep for windows. Powergrep allows me to search a text file with regular expression inout. I tried using the search as        title='[a-zA-Z0-9]  It shows the correct matches, but it matches only first character of the string and writes only the first character of the text string matched to the second txt file, not all string.   I want all string to be matched and written to the second file.  What is the correct regular expression or way to do what i want to do, using powergrep?  -AD.
got me wondering about the differences between these three ways of measuring size: a kibibyte, a kilobit, and the conventional kilobyte.  I understand that these measurements have different uses (data transfer rate is measured in bits/sec), but I'm not quite sure if I can tell the difference between Mb and MB and MiB.  Here is a comment, reproduced below, taken from  (emphasis mine).     The C64 has 65536 bytes of RAM. By   convention, memory size is specified   in kibiBytes, data transfer rates in   kilobits, and mass storage in   whatever-the-manufacturers-think-of-now-Bytes. Harddrives use T, G, M and k on the   label, Windows reports the size in Ti,   Gi, Mi and ki. And those 1.44MB   floppys? Those are neither 1.44MB nor   1.44MiB, they are 1.44 kilokibibytes. That's 1440kiB or 1'474'560 bytes. –   Third Why should I declare a virtual destructor for an abstract class in C++? I know it is a good practice to declare virtual destructors for base classes in C++, but is it always important to declare virtual destructors even for abstract classes that function as interfaces?

Isomorphism of a product $C_n \times C_m$ of cyclic groups with the cyclic group $C_{mn}$ Given that $C_n$ is a cyclic group of order $n$, what conditions must integers $n$ and $m$ satisfy such that the group $C_n \times C_m$ is isomorphic to C$_{mn}$?   So I attempted to investigate a few lower-order cyclic groups to find a pattern. In particular, I looked at $C_2 \times C_3$ and compared it to $C_6$. Here are a couple of diagrams:  $C_2 \times C_3$ -   $C_6$ -   They Cayley tables look pretty different (identity elements are all over the place for $C_2 \times C_3$) so I concluded that they are not isomorphic.  I did the same for $C_2 \times C_4$ and $C_8$:  $C_2 \times C_4$ -   $C_8$ -   Again, I arrived at the conclusion that the 2 groups are not isomorphic due to their Cayley table structure.  It seems I'm stuck now. Are my conclusions wrong for the examples I examined? If so, how do I find the conditions for the general case of comparing $C_m \times C_n$ with $C_{mn}$? Ethernet indicator in OSX menu bar I am using OSX 10.7  When I move between different ethernet networks (e.g., at work using ethernet on an external display, at home using thunderbolt ethernet), the ethernet does not always connect. However, I don't get immediate feedback. Instead, I connect to wi-fi. However, wi-fi is both slower and less reliable than ethernet. Thus, I'd like to know whether I am connected to ethernet or not. Of course I can go into preferences and network settings to see whether I'm connected to ethernet, but it would be better if there was some form of indicator in the status bar, just as there is for wi-fi. Thus, my question:  Is there a way of getting an indicator of ethernet connectivity in the OSX menu-bar?  Perhaps there is a free application that can do this. (Revised) Prove that $\phi$ is a group homomorphism and find the kernel. Quoting " Let $\phi : \Bbb Z \rightarrow \Bbb Z$ be given by $\phi(n) = 7n$. Prove that $\phi$ is a group homomorphism. Find the kernel, and the image of $\phi$."   My understanding:  Part 1:   Given $n,m \in \Bbb Z$, let's check that $\phi(n+m) =\phi(n)+\phi(m)$  $$\phi(n+m) = 7(n+m) = 7n + 7m = \phi(n)+\phi(m)$$  Therefore as the group operation in $\phi$ is preserved, $\phi$ is a group homomorphism.  Part 2 (revised):   $\phi$ is one-to-one as:  $\space \space \phi (n) = \phi(m) \Rightarrow 7n =7m \Rightarrow n=m  $. We also know that $\phi(e)=e$ by the property of homomorphism. Therefore, no other object than $0$ in the domain can map to $0$ in the codomain. It follows that: $$\ker(\phi)=\{ x \in \Bbb Z : \phi(x)=e\}=\{e\}$$   Part 3 (revised):  I claim that the only possible image-elements of $\phi$ are the multiples of $7$ in $\mathbb Z$ denoted $7\mathbb Z$.   To prove this I have to show that Im$(\phi) \subset 7 \Bbb Z$ and that $ 7 \Bbb Z \subset $ Im$(\phi)$.  Proving Im$(\phi) \subset 7 \Bbb Z$ :      $\forall y \in $ Im$(\phi)$ such that $  y =\phi(x)$ where $x \in 7 \Bbb Z$. It follows that $y \in 7 \Bbb Z$, therefore Im$(\phi) \subset 7 \Bbb Z$   Proving $ 7 \Bbb Z \subset $ Im$(\phi)$:   $\forall y \in  7\Bbb Z$ such that $  y =7x$ where $x \in \phi(x)$. It follows that $y \in \phi(x)$, therefore $ 7 \Bbb Z \subset $ Im$(\phi)$.   Any input to my understanding is much appreciated. How to ssh into a server running on a home network, behind a router?

PythonTEX ? Just want to get clarification on something we're noticing in our org. Its regarding a new integration user we've created for an external application to connect to Salesforce. We also created a Connected App for this application to authenticate using OAuth. All of this is setup and working up to this point.   But one thing that we don't understand is there is a related list on the integration user detail page named "OAuth Connected Apps". We're concerned because although we are connecting fine and data is getting return to the external application no records are showing up in this "OAuth Connected Apps" related list. Should we expect to see Authorization or Access tokens in this list?   We just want to make sure we aren't bypassing the connected app in anyway, which we assume not, but just want to run it by the community and see. All comments are appreciated. Thanks ahead of time for the support. A rearrangement of an absolutely convergent complex series is also absolutely convergent I just completed the following proof.  Is it valid?   Let $\sum_{k=1}^{\infty} a_k$ be an arbitrary convergent series that also converges absolutely.  Then $\sum_{k=1}^{\infty} a_k \in \mathbb{C}$ and $\sum_{k=1}^{\infty} |a_k| \in \mathbb{R}$. Let $\{b_k\}$ denote a rearrangement of the $\{a_k\}$.  That is, we have that $\{a_k\} = \{b_k\}$ yet $a_i = b_i$ needn't hold. We will first show that $\sum_{k=1}^{\infty} b_k$ converges absolutely (immediately implying it converges non-absolutely).  We will use the Cauchy Criterion on the partial sums of $\sum_{k=1}^{\infty} |b_k|$ to demonstrate this. First let $\epsilon &gt; 0$. Consider that since $\sum_{k=1}^{\infty} |a_k| \in \mathbb{R}$, we have that $\exists N_1 \in \mathbb{N}$ s.t. for all $N_1 &lt; m &lt; n$ we have   $$ \sum_{k=m}^n |a_k| \le \epsilon. $$ Now let $0 &lt; N_2$ be large enough s.t $\{a_1, \ldots , a_{N_1}\} \subseteq \{b_1, \ldots , b_{N_2}\}$.  Let $M &gt; max\{N_1, N_2\}$.  Let $M &lt; m' &lt; n'$.  Then since $\{b_k\} - \{b_1, \ldots , b_{m'}\} \subseteq \{a_{N_1}, a_{N_{1}+1},  a_{N_{1}+2} \ldots\}$, we will have that   $$ \sum_{k=m}^n |a_k| \le \epsilon \implies \sum_{k={m'}}^{n'} |b_k| &lt; \epsilon. $$ Then we have that   $$ \left| \sum_{k={m'}}^{n'} |b_k| \right| = \sum_{k={m'}}^{n'} |b_k| &lt; \epsilon $$  so that since $\epsilon$ was arbitrary, we have obtained that   $$ \left| \sum_{k=1}^n |b_k| - \sum_{k=1}^m |b_k|  \right| = \left| \sum_{k=m}^n |b_k|  \right| \rightarrow 0 $$  so that via the Cauchy Criterion for Convergence  we have that $\sum_{k=1}^{\infty} |b_k|$ converges to some  value in $\mathbb{R}$ as desired. Then it follows that $\sum_{k=1}^{\infty} b_k$ is absolutely convergent (and hence also just convergent).   $\square$ Generate dynamic XY coordinate labels for dataframe corners in ArcGIS layout I need to label the four corners of a dataframe as shown in the image.
