Return single column from a multi-dimensional array Detect edits to add [SOLVED] or [RESOLVED] to the title and direct the user to add an answer Users often ask questions that they answer for themselves. Good for them. And good for us.  Symptom  The correct procedure seems to be:   Write new answer to own question  Wait two days Accept own answer   The incorrect, but fairly popular, procedure seems to be:   Edit the question to include the solution Put "[SOLVED] or [RESOLVED]" in the title   Proposed solution  Users should be warned when using the word "solved", delimited in any way, in a question title. This could be "[SOLVED]", "(solved)", or even "Solved - ". I imagine this:   The user tries to submit an edit that adds "solved" such that the word "solved is delimited. The user is brought to a warning page. If the only edit to the question was appending new lines (such as adding an "edit:" paragraph), that edit is copied into a text box The page mentioned in 1 is shown as follows:     $StackSite marks questions as answered when you accept an answer. You can accept an answer by clicking the green check mark next to that answer. There's no need to put "SOLVED" or "RESOLVED" in the title!      Are you answering your own question?      Create a proper answer to your question:         Move your edit to a new answer.   Write your answer.   If nobody writes a more correct or thorough answer after two days, come back and accept your answer.         By doing this, you remove your question from the Unanswered Questions list. You also allow other $StackSite users to vote your answer up. Thanks for helping out!      TEXT BOX WITH EDITS GOES HERE, FOLLOWED BY "POST YOUR ANSWER" BUTTON      Not answering your own question?      Sorry for slowing you down.      OVERVIEW OF EDIT, FOLLOWED BY "SAVE EDITS" BUTTON    Discussion  This would likely reduce the number of [RE]SOLVED questions that appear. However, it's unclear whether this should be a community moderation issue or a feature request issue. The increased engineering work required in building in the interstitial page is probably quite nontrivial, whereas this type of question makes up well under .  Note: Google also provides a . 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...? For $u:\mathbb{R}\times [0,1]$ with boundary conditions $u(0,x)=\cos (2\pi x)$ and $u(t,0)=u(t,1)$.   Solve $u_t=u_{xx}+u_x$.  I had this on an exam and tried to write $u$ as a product of two single variate functions and convert to an ode using the usual methods but things got messy and I couldn't finish. I also tried to write $u$ as a Fourier series in $x$ with coefficients $a_k(t)$ depending on $t$, but this also didn't seem to yield anything.  Is there a more clever way to approach this, possibly with Fourier series? I heard from a friend there may be a Fourier transform method since the equation was "homogeneous in momentum space."   Thanks! How do I convert html page to SharePoint 2013 master page? There is functionality provided in SP2013 for converting html page to SharePoint master page. I have tried this functionality but each time it convert nothing. Is there any specific method that I need to follow? Or is there any specif layouts of html page need to be converted into SP 2013 master page? When should I use Inline vs. External Javascript? I would like to know when I should include external scripts or write them inline with the html code, in terms of performance and ease of maintenance.  What is the general practice for this?  Real-world-scenario - I have several html pages that need client-side form validation. For this I use a jQuery plugin that I include on all these pages. But the question is, do I:   write the bits of code that configure this script inline? include all bits in one file that's share among all these html pages? include each bit in a separate external file, one for each html page?   Thanks. Does text in brackets invoke the "an" vs. "a" rule? I want to install selenium webdriver in my Ubuntu 16.04 system for python Finding $\lim \limits_{x \to 0} \frac{1 - \cos x}{x}$, given $\lim \limits_{x \to 0} \frac{\sin x}{x} = 1$ Is there an online community to find travel partners (for mountains, sightseeing etc.)? Is there an online community to find travel partners for mountain trekking or sightseeing, or anything else?  I don't want to travel to foreign mountains alone, but I don't know where to search for company. There's a great community for accommodation (I mean CouchSurfing) so I think there should be something in "reverse" direction (searching not the place to stay but the people to go with). I just ran into the problem of embedding fonts while trying to publish with lulu.com. Although everyone apparently is 'supposed' to handle those 35 standard fonts for some strange reason they won't accept pdf's without them included. So one way that according to  is supposed to work (I haven't tried yet, but hopefully it does work) is to convert the pdf to ps and then back to pdf and include the fonts at that time:  pdftops file.pdf ps2pdf14 -dPDFSETTINGS=/prepress file.ps   But this feels at least to me like the wrong way of doing things. Is there some way of passing the parameter directly to pdflatex to tell it to embed those fonts?   And, if not -- How do we go about getting such a feature? (Because it can't only be me who has this sort of problems) Changing ChildOf constraint influence to 0, but keeping the position it had as a child I had a sword object rigged with a single bone, with a ChildOf constraint making it a child of a sheath (with an influence of 1). Throughout an animation i move the sheath, and the sword bone follows as expected.  However, i cant seem to lower the influence of the sheath to zero and still have the sword retain the position it was just at, and I am wondering how i should go about making this happen.  Thanks for your time. Many anime do not follow the manga history and are made shorter. However there are a few that do follow it or try to finish the history with the manga like the big three (Naruto, Bleach, One Piece), Death Note, and FMA Brotherhood. But others finish the anime without the real ending like FMA, Ouran High School, Pandora Hearts, Tsubasa Reservoir Chronicle. Why is this so? Is it because of the high cost? Or the lack of popularity? When $f(x+1)-f(x)=f'(x)$, what are the solutions for $f(x)$? The question is:     When $f(x+1)-f(x)=f'(x)$, what are the solutions for $f(x)$?   The most obvious solution is a linear function of the form $f(x)=ax+b$. Is this the only solution?  Edit  I should add that $f:\mathbb R\to\mathbb R$ to the question. IPv4 vs IPv6 priority in Windows 7 I have IPv6 connectivity through Hurricane Electric tunnel. Since IPv6 day this year, many services (google.com, facebook.com, etc.) enabled IPv6 on their main domains. On my Windows machine, IPv6 is preferred over IPv4. This means that whenever I visit Google, all traffic goes through my tunnel to Hurricane Electric, which raises the latency by more than 100%:  C:\&gt; ping www.google.com  Pinging www.l.google.com [2001:4860:8005::68] with 32 bytes of data: Reply from 2001:4860:8005::68: time=85ms Reply from 2001:4860:8005::68: time=84ms Reply from 2001:4860:8005::68: time=112ms Reply from 2001:4860:8005::68: time=86ms  Ping statistics for 2001:4860:8005::68:     Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds:     Minimum = 84ms, Maximum = 112ms, Average = 91ms   C:\&gt; ping -4 www.google.com  Pinging www.l.google.com [173.194.79.103] with 32 bytes of data: Reply from 173.194.79.103: bytes=32 time=28ms TTL=48 Reply from 173.194.79.103: bytes=32 time=28ms TTL=48 Reply from 173.194.79.103: bytes=32 time=55ms TTL=46 Reply from 173.194.79.103: bytes=32 time=29ms TTL=46  Ping statistics for 173.194.79.103:     Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds:     Minimum = 28ms, Maximum = 55ms, Average = 35ms   Question: How can I make Windows 7 to always prefer IPv4, when both IPv4 and IPv6 records are available for a specific domain name? When voting to migrate an off-topic question, why is the list of sites limited? Earlier, I voted to close  as off-topic.  The question has since been closed.  There is an , but it didn't show up in the list when I selected "off-topic".  The options were:   Meta Stack Overflow Server Fault Super User Webmasters Programmers   Questions:   Should Wordpress appear in this list? Are there any other sites that should appear in the list?   Should all non-beta sites appear in that list by default? The following C++ code uses a ifstream object to read integers from a text file (which has one number per line) until it hits EOF. Why does it read the integer on the last line twice? How to fix this?  Code:  #include &lt;iostream&gt; #include &lt;fstream&gt; using namespace std;  int main() {     ifstream iFile("input.txt");    // input.txt has integers, one per line      while (!iFile.eof())     {         int x;         iFile &gt;&gt; x;         cerr &lt;&lt; x &lt;&lt; endl;     }      return 0; }   input.txt:  10   20   30   Output:  10   20   30   30   Note: I've skipped all error checking code to keep the code snippet small. The above behaviour is seen on Windows (Visual C++), cygwin (gcc) and Linux (gcc). facl ignoring the "x" permission but only on files When I use setfacl to manage on what permissions should the children files / directories have, for some reason the files have all the permissions except the execute ("x") one.  someuser@someuser-MS-7816:/opt/lampp/htdocs/project$ getfacl . # file: . # owner: someuser # group: webs # flags: -s- user::rwx group::rwx other::rwx default:user::rwx default:group::rwx default:other::rwx  someuser@someuser-MS-7816:/opt/lampp/htdocs/project$ touch file someuser@someuser-MS-7816:/opt/lampp/htdocs/project$ mkdir dir someuser@someuser-MS-7816:/opt/lampp/htdocs/project$ ls -l total 4 drwxrwsrwx+ 2 someuser webs 4096 paź 31 13:35 dir -rw-rw-rw-  1 someuser webs    0 paź 31 13:35 file   I thought it has something to do with umask but changing it in various ways never gives the expected result unless I'm missing something.
