How to deal with bibliography items containing long URLs?
I want to use the top half of the circle to make a cut but whenever I apply the boolean modifier, the circle just stays there and becomes attached to my other object.  I've managed to make the cut in a standard cube but not sure why it's not working for this...? I would like to know the equipment and the step by step process, as I have already tried to do it, but it didn't work.  I have already watched several videos, but it is not the same to talk to someone that really loves, and knows how to do it. I don't know anybody that knows how to brew anything xD With variable length instructions how does the computer know the length of the instruction being fetched? Do you need to take the Hide action when you are Invisible, make no noise and leave no traces? The Situation: Lets say you are under the effect of Invisibility.  An invisible creature is impossible to see without the aid of magic or a special sense. For the purpose of hiding, the creature is heavily obscured. The creature's location can be detected by any noise it makes or any tracks it leaves.  And you are wearing the Boots of Elvenkind  While you wear these boots, your steps make no sound, regardless of the surface you are moving across. You also have advantage on Dexterity (Stealth) checks that rely on moving silently.  Now your groups ranger or druid casts Pass Without Trace on you.  [...] can’t be tracked except by magical means. A creature that receives this bonus leaves behind no tracks or other traces of its passage.  My Question(s): I know that when you are Invisible and you did not hide, you are still detectable because of the noise and the track you leave behind. But the Boots of Elvenkind and Pass Without Trace take care of that. So:  Are you still required to take the hide action in this situation if you don't want enemies to know your location/presence? If so, why? What gives away your location? If not and you are under the effect of greater Invisibility do you get the benefits of &quot;Unseen Attackers and Targets&quot; for every attack you make when you move between attacks? (You would give away your location, but are not detectable, so completely hidden again when you move) Where should I post my sum-up of the answers, as the OP? Sometimes as the OP (question asker), after reading through all the answers, I have my own sum-up about them. I want to tell people and all further readers about my feeling and comprehension about my desired answer and how all the answers helped towards solving my problem.  Where's the correct place to put that information? Things I've considered:   Edit into my question: No because that's not part of the question A comment under the question: I dislike that due to limited formatting in comments and its subject to removal (though the latter won't be the case) A comment under the highest-scored or the accepted answer: Still the same reason above. This is, for the time being, the place I'm posting that. A separate answer: Those thoughts probably don't qualify as an answer The Ubuntu installer does not allow me to install on NTFS partitions, but certain circumstances requires me to do so. Is it possible? I'm trying to iterate over the words of a string.  The string can be assumed to be composed of words separated by whitespace.  Note that I'm not interested in C string functions or that kind of character manipulation/access. Also, please give precedence to elegance over efficiency in your answer.  The best solution I have right now is:  #include &lt;iostream&gt; #include &lt;sstream&gt; #include &lt;string&gt;  using namespace std;  int main() {     string s = "Somewhere down the road";     istringstream iss(s);      do     {         string subs;         iss &gt;&gt; subs;         cout &lt;&lt; "Substring: " &lt;&lt; subs &lt;&lt; endl;     } while (iss); }   Is there a more elegant way to do this? Showing $\int_x^{x+1}f(t)\,dt \xrightarrow{x\to\infty}0$ for $f\in L^2 (\mathbb{R})$ Show that if $f\in L^2 (\mathbb{R})$ then    $$\lim_{x \rightarrow \infty} g(x)=0,$$   where    $$g(x)=\int_x^{x+1}f(t)\,dt$$   Since $f \in  L^2 (\mathbb{R})$ then $f \in L^2[x,x+1]$ for every $x$. Then  $$|g(x)| \leq \left(\int_x^{x+1} f(t)^2 dt\right)^{\frac{1}{2}} \int_x^{x+1} 1 dt$$ $$|g(x)|\leq \left(\int_x^{x+1} f(t)^2 dt\right)^{\frac{1}{2}}$$ Get the client IP address using PHP Error: Account is Not Allowed To Suggest Edits I get this message while trying to edit a post on SuperUser while using the iOS mobile app. I have at least 101 reputation on SU, more than enough to be able to edit posts.

Show that the polynomial $f = x^2 + 2 x + 3 \in \mathbb{Z}_5[x]$ is primitive. How many monic primitive quadratic polynomials are there in $\mathbb{Z}_5[x]$?  Any help would be greatly appreciated. Make it possible to retract comment flags I misread the content of a comment, and flagged it. Then I realized that the comment wasn't what I had initially thought. Would it be possible to have the ability to retract comment flags, just like we have the ability to retract flags on questions and answers?  I'm aware of this &#32;. But the answer there is just that it's not possible. At the time it was not possible to retract any flags.   This is a separate  which requests that it may become possible to retract comment flags.  If I've realized a flag was a mistake, I think it's unnecessary to keep it in the queue of content the moderators have to look at. Also, it would add an unnecessary "rejected" to the flaggers statistics. Sure, people should think before they flag. But everyone makes mistakes sometimes. Speed of light in a gravitational field?

I'm a bit confused about the difference between these two concepts. According to Wikipedia the  and  are closely related concepts. From my understanding, the Fermi energy is the highest occupied energy level of a system in absolute zero? Is that correct? Then what's the difference between Fermi energy and Fermi level?
