Connecting two points on the boundary of an open, connected and bounded set $Q\subset \mathbb{R}^2$ with a path $\gamma\subset \overline{Q}$
Is the closure of path-connected set path connected?
How to hyperlink only the year part when using natbib and hyperref I am using the natbib and hyperref packages:  \usepackage{natbib}  \usepackage[pagebackref=true, plainpages=false, bookmarks, bookmarksnumbered, colorlinks, linktocpage=true, linkcolor=blue, citecolor=blue, filecolor=black, urlcolor=blue]{hyperref}   With my current settings (above) both the name and the year are hyperlinked.  My question is, whether there is a way to hyperlink (or color) only the year-not the author(s).   I have the impression reading this post  that biblatex does it by default. However changing to biblatex is not an option for me at this point.  Any helpful comments will be greatly appreciated. Installing ArcView 3 on 64-bit Windows? How do I install ArcView 3 on 64bit Windows?   There are numerous threads on the Esri forums for how to accomplish this, but the solutions are scattered, inconsistent and disjointed.   This is a request to post integrated and "cleaned-up" solutions, don't just copy and paste. Please indicate if the method is specific to x64 XP, Vista, or 7 (and post seperately, e.g. win7 method in one answer, vista in another). Can the problem of unification of Quantum Mechanics and General Relativity be converted into a pure Mathematical problem? I mean to say, can you make someone understand the problem who only knows Mathematics, even if a Physics description is absent? I mean, describing the problem with unification using pure Mathematical formulation.  Can we make the problem seem as if it has nothing to do with the real world and describe it only as a problem of mathematics? How to disable automount in nautilus's preferences Enable fractional scaling for Ubuntu 18.04 My friend had a  on the board with 10 counters on it.  If I destroy it and he sacs it in response to gain the life, is there anything that can be done about that?  Like, can I put another destroy artifact on the stack to resolve before his sac resolves? While reviewing "First Posts" on Stack Overflow, I often come across new users posting comments as answers. It seems (at least to me) they are not doing this because they are unaware of how Stack Overflow works but because they can't comment on any question they are forced to put it as answer.  I have found duplicate questions for my request like:   ,  and    but the best explanation I have found is an  to .     I think the main reason this isn't supported is there's no way to   downvote comments, which would make them attractive to spammers. If   somebody comments on the top answer in a question the only way to get   rid of it is for six people to flag it. Comment flags don't show up on   10k tools, so it needs to be six people that happen to stumble across   the spam comment, or a moderator that checks the list manually. People   can comment every 15 seconds, so that can get out of hand pretty   quickly. Comments also aren't listed on the user's profile page, so   it's hard to see at a glance if a user has been spamming   So I am suggesting allowing new users (with less than 50 reputation points) to comment only 5 times every day or only 25 times times until they reach 50 reputation points or any other variation of it. Can I mix sources from different ubuntu versions? As we know that we are using  for installing packages and repositories configuration file located at /etc/apt/sources.list.  I am using Ubuntu 12.10 (Quantal Quetzal) which reaches . That means no updates or support. So, the question is, can I use sources.list file from another version, say Ubuntu 12.04 LTS, and will it negatively affect the system. how to get the string-lengths stored in array (C) If $I$ is a non-zero proper ideal of a commutative integral domain, is it possible for $I$ to be its own square? QGIS save postgis table error : no result buffer I've a polygon layer on PostGIS, and when I try to add featureS using QGIS it gets error when I save the edit.   Here is the error notification "no result buffer".     I found a similar case here : . But it doesn't give me the answer to solve it. Any ideas ? Solve $$u_{xx}-3u_{xt}-4u_{tt}=0$$ where $u(x,0)=x^2$ and $u_t(x,0)=e^x$.  My workings so far: I have factored the differential equation in the following way: $$(\delta_x-4\delta_t)(\delta_x+\delta_t)=0$$ where $\delta_x=\frac{\delta}{\delta x}$ etc. Now if we let $v$ be the solution to $(\delta_x+\delta_t)u$ then we have the following two equations: \begin{eqnarray*} (\delta_x+\delta_t)u=u_x+u_t=v\\ (\delta_x-4\delta_t)v=v_x-4v_t=0 \end{eqnarray*} Now for $v$ we simply find $$v=h(t+4x)$$ where $h$ is an arbitrary function of one variable. Now what remains is find $u$ such that $$u_x+u_t=h(t+4x)$$ I am stuck here, I thought about making a change of variables $\zeta=x+t$ and $\eta=x-t$ and thus using the product rule to show that $u_x=u_{\zeta}+u_{\eta}$ and $u_t=u_{\zeta}-u_{\eta}$ and thus $u_x+u_t=2u_{\zeta}$ and we need to solve $$u_{\zeta}=h(t+4x)$$ (I left out the factor 2 because $h$ is an arbitrary function). Do I simply integrate now and conclude $$u=f(\zeta)h(t+4x)+g(\eta)=f(x+t)h(t+4x)+g(x-t)$$ This seems wrong to me...  Some help would be greatly appreciated! How to run .sh script with keybind How to stop the Facebook app from updating itself automatically? I have the Facebook app installed on my Android 7 phone.   Auto-update is disabled for all applications on my Play Store account I have disabled installation from unknown sources   For some reason, whenever there is an update of the Facebook app, it automatically updates itself even though I disabled auto-updates for all applications.  How to stop the Facebook app from updating itself automatically? While writing a proposal at work today I needed to mention a list of things and within that list were multi-part items. It seems like replacing the comma with a semi-colon in this situation would make the sentence easier to understand, but is it correct usage?  With standard punctuation this could get confusing:       Some of my favorite things to do are   camping, playing football and   baseball, watching Laurel and Hardy   Movies, and traveling.   Proposed alternative. Is this acceptable usage?       Some of my favorite things to do are   camping; playing football and   baseball; watching Laurel and Hardy   Movies; and traveling.

Once you pick them up they stay in your inventory with a weight of 0 and a value of 300. Will I need them later ? Do I lose the bonus if I sell them or drop them somewhere ? Same with the magazines.  Is there any disadvantage to selling them ? How do you compute negative numbers to fractional powers?
