Match content between words I'd like to create a regex to match content between tags.  My regex that is not working : new RegExp("page.content_before(.+)\/page.content_before", "g").exec(myText)[0]  myText :  page.title Accueil /page.title  page.content_before [slides]  &lt;div&gt;   &lt;div class="line"&gt;     &lt;div class="col-12"&gt;       Lorem ipsum dolor sit amet, consectetur adipisicing elit. Odit excepturi consequatur inventore alias ducimus tenetur libero iste nesciunt soluta esse et debitis aliquid, voluptatum placeat veritatis! At dolorem repellat doloremque!     &lt;/div&gt;   &lt;/div&gt; &lt;/div&gt;  &lt;div&gt;   &lt;div class="line"&gt;     &lt;div class="col-12"&gt;       [articles]     &lt;/div&gt;   &lt;/div&gt; &lt;/div&gt;  &lt;div&gt;   &lt;div class="line"&gt;     &lt;div class="col-12"&gt;       [vehicles]     &lt;/div&gt;   &lt;/div&gt; &lt;/div&gt; /page.content_before  page.content &lt;div class="line"&gt;   &lt;div class="col-8"&gt;     Lorem ipsum dolor sit amet, consectetur adipisicing elit.

How do I match any character across multiple lines in a regular expression? For example, this regex  (.*)&lt;FooBar&gt;   will match:  abcde&lt;FooBar&gt;   But how do I get it to match across multiple lines?  abcde fghij&lt;FooBar&gt;
How can I prevent iTunes from auto starting when I plug in an iOS device? If a group satisfies $x^3=1$ for all $x$, is it necessarily abelian? I know that any group satisfying $x^2=1$ for all $x$ is abelian. Is the same true if $x^3=1$? I don't think it is, but I can't find a basic counterexample. Reputation widget crash I have an issue with crashing reputation widget when it's added to the home screen. When I add it for the first time, it says "Please login before using this widget" (even though the app itself is logged in already). So I open the app, go back to the home screen, add the widget again and it crashes (and it's not added to the home screen). When I'll try to add it again, it says "Please login before using this widget" again. And then it just repeats - "Please login...", execute the app, crash, "Please login...", etc.  Restart of the device didn't make any change.  I have found .  My set up:  Stack Exchange app version: 1.0.89 Android version: 5.0.1 Device: Samsung Galaxy S4 Many years ago I read a book or story where a group of people discover a dark city - maybe on another planet - which appears devoid of life but is in very good condition. As they gradually explore the city one of the them falls into a trap and is cut to pieces by something mechanical. This detail I can remember as it was a pretty gruesome idea. I don't know the ending but my guess is that none of them make it out alive. Java, pointer like way to program this what is PGP public key block? There's PGP public key block posted on some websites (eg. ).  It's not hex code. it uses much more alphabet characters. What is it?  Why is this information posted? how can i use it?

I found two questions  and  about this issue but there is no obvious answer or explanation yet.I enforce the same problem where the validation error is less than training error in my Convolution Neural Network. What does that mean? How to change specific values in a List Proof: How many digits does a number have? $\lfloor \log_{10} n \rfloor +1$ I read recently that you can find the number of digits in a number through the formula $\lfloor \log_{10} n \rfloor +1$ What's the logic behind this rather what's the proof? Unable to catch JsonMappingException Proof that every number ≥ $8$ can be represented by a sum of fives and threes. Can you check if my proof is right?  Theorem.  $\forall x\geq8, x$ can be represented by $5a + 3b$ where  $a,b \in \mathbb{N}$.  Base case(s): $x=8 = 3\cdot1 + 5\cdot1 \quad \checkmark\\ x=9 = 3\cdot3 + 5\cdot0 \quad \checkmark\\ x=10 = 3\cdot0 + 5\cdot2 \quad \checkmark$  Inductive step:  $n \in \mathbb{N}\\a_1 = 8, a_n = a_1 + (x-1)\cdot3\\ b_1 = 9, b_n = b_1 + (x-1)\cdot3 = a_1 +1 + (x-1) \cdot 3\\ c_1 = 10, c_n = c_1 + (x-1)\cdot3 = b_1 + 1 + (x-1) \cdot 3 = a_1 + 2 + (x-1) \cdot 3\\ \\ S = \{x\in\mathbb{N}: x \in a_{x} \lor x \in b_{x} \lor x \in c_{x}\}$  Basis stays true, because $8,9,10 \in S$  Lets assume that $x \in S$. That means $x \in a_{n} \lor x \in b_{n} \lor x \in c_{n}$.  If $x \in a_n$ then $x+1 \in b_x$,  If $x \in b_x$ then $x+1 \in c_x$,  If $x \in c_x$ then $x+1 \in a_x$.  I can't prove that but it's obvious. What do you think about this? What is the motivation behind axiomatically forcing the underpinning group of a ring to be abelian? Noncommutative rings are vastly more complex than commutative ones, so I am assuming that allowing the additive operation to be noncommuting would just make matters worse. Is there something deeper here, or is this a restriction for the sake of convenience and simplicity? e.force:navigateToURL: [Cannot read property 'setParams' of undefined] Why is the detection of gravitational waves so significant? LIGO has announced the detection of gravitational waves on 11 Feb, 2016. I was wondering why the detection of gravitational waves was so significant?   I know it is another confirmation of general relativity (GR), but I thought we had already confirmed GR beyond much doubt. What extra stuff would finding gravitational waves teach us? Is the detection of gravitational waves significant in and of itself, or is there data which can be extracted from the waves which will be more useful? How can I gear my follower post 2.0? I'm a little confused as to how I'm supposed to gear up my follower since the installation of smart loot in Loot 2.0. My follower still has most pre loot 2.0 items because I have yet to find comparables that are rolling with the right affixes.   To be clear, I play a DH and so I used the Templar as my tank. I very rarely find items that roll with Strength because smart loot sees my DH and rolls Dex for me instead. With the use of the Enchantress I thought it would get better because I could replace Dex with Strength...but that's not true. It seems as though the Enchantress will only roll Dex for me too.   With the auction house down for good, no outlet for trading, and the installation of smart loot, it seems that gearing a follower has become almost impossible unless I want to jump on another character that uses strength and get items that way. I want to find items that I can use while I'm playing. How do I gear my follower post Loot 2.0? Do I have any options other than character jumping? Prove that some topology is not metrizable
