Getting polygon boundaries of City in JSON from Google Maps API? When searching Google Maps for a city, the city's administrative boundary is displayed.    Is there a way to get the polygon boundaries of City in a JSON format using google maps api? I accidentally unset all the directories of $PATH while trying to add a new one in ~/.bashrc. I opened a new terminal window as I was editing and now $PATH is empty. I'm worried if I boot from another drive to find the $PATH I won't be able to boot into this drive again.  Basically, what is the default result of echo $PATH? How do I calculate the power consumed by a lightbulb? I'm studying a lightbulb and its variable resistance, given by the expression:  $R(T) = Ro[1 + α(T-T_0)]$, where $R_0$ is the resistance of the lamp at $T_0$.  In this case, $R$ is not given by Ohm's law ($V=Ri$). So, which expression can I use to calculate the power consumed by a lightbulb?   $P = R\cdot i^2$ $P = \frac{V^2}{R}$ $P = V\cdot i$ (I don't think I can use this one)   I have measured the current and the e.p.d. at the bulb using instruments. Show $GCD(a_1, a_2, a_3, \ldots , a_n)$ is the least positive integer that can be expressed in the form $a_1x_1+a_2x_2+ \ldots +a_nx_n$ Given $a_1, a_2, a_3, \ldots , a_n$ not all zero, show $\gcd(a_1, a_2, a_3, \ldots , a_n)$ is the least positive integer that can be expressed in the form $a_1x_1+a_2x_2+ \ldots +a_nx_n$. Also deduce $a_1x_1+a_2x_2+ \ldots +a_nx_n = b$ has solutions $\iff \gcd(a_1, a_2, a_3, \ldots , a_n)|b$.   I know that $ax+by=n$ has integer solutions $\iff \gcd(a,b)|n$. I'll need to use induction to show $a_1x_1+a_2x_2+ \ldots +a_nx_n = \gcd(a_1, a_2, a_3, \ldots , a_n)$ has solutions, and then I will be able to say that as $\gcd(a_1, a_2, a_3, \ldots , a_n) | a_1x_1+a_2x_2+ \ldots +a_nx_n $ for any $x_1,x_2, x_3 \ldots x_n$ then $c \leq \gcd(a_1, a_2, a_3, \ldots , a_n)$ and $c \geq \gcd(a_1, a_2, a_3, \ldots , a_n)$, and thus $c=\gcd(a_1, a_2, a_3, \ldots , a_n)$. How can I rewire half switched receptacles? In my bedroom the bottom half of all receptacles are controlled by one switch. Is it possible to have just one receptacle with top and bottom hot all the time?  The top half is hot all the time the bottom half is controlled by one switch.  Keep in mind there are six other receptacles in this room that are the same way controlled by the same switch. When I took the receptacle out the right side tab had been removed.  The top right screw had a black wire, the bottom right had a red wire, the top and bottom left screws had separate white wires.  I changed the receptacle out as suggested, I capped off the red wire and I capped off the white wire that was attached to the bottom left screw. I attached the other white wire to the top left screw and attached the black wire to the top right screw. I now have none of the receptacles working at all. What did I do wrong? "'key' is not valid for passed 'access_token', token not found" when trying to login using Google on Android SE app I am using nginx/0.7.68, running on CentOS, with the following configuration:  server {     listen       80;     server_name ***;     index index.html index.htm index.php default.html default.htm default.php;      location / {             root   /***;             proxy_pass   http://***:8888;             index  index.html index.htm;     }     # where *** is my variables   The proxy_pass is to a DNS record whose IP changes frequently. Nginx caches the outdated IP address, resulting in a request to the wrong IP address.  How can I stop nginx from caching the IP address, when it is outdated? Setting Zero values back to NULL Heroku deployment failed because of sqlite3 gem error I'm using Java, and need to generate a simple, standards-compliant RSS feed. How can I go about this? fatal: bad ownership or modes for chroot directory component "/" in SFTP I've been trying to configure sftp in a debian server.sshd_config:  Subsystem sftp internal-sftp  UsePAM no  Match User sftpUser ChrootDirectory /users/sftp/sftpUser ForceCommand internal-sftp AllowTcpForwarding no X11Forwarding no   Directories:   drwxr-xr-x   3 root      root      4096 Oct 20 10:59 users   drwxr-xr-x   3 root      root      4096 Oct 20 11:00 sftp   drwxr-xr-x   2 root      root      4096 Oct 20 11:00 sftpUser   cat /var/log/auth.log  Oct 20 10:58:22 w1 sshd[24634]: Accepted password for sftpUser from 201.156.103.213 port 34106 ssh2 Oct 20 10:58:22 w1 sshd[24636]: fatal: bad ownership or modes for chroot directory component "/"   sftpUser no home, bin/falseand member of user group.  In the client side I'm getting the famous Write failed: Broken pipe and then the connection is dropped.  Commenting the ChrootDirectorycommand in sshd_config makes the connection, but get's the user loose.  What am I doing wrong ? Why double-headed arrows when the direction of node is specified? I am quite puzzled when drawing the connection of nodes.  \usepackage{xcolor} \definecolor{darkblue}{HTML}{1F4E79} \definecolor{salmon}{HTML}{FF9C6B} \tikzstyle{cell} = [rectangle, minimum width=1cm, minimum height=0.5cm,text centered, draw=black, fill=salmon] \tikzstyle{state} = [rectangle, minimum width=1cm, minimum height=0.5cm,text centered, draw=black, fill=darkblue] \tikzstyle{arrow} = [thick,-&gt;,&gt;=stealth]  \begin{tikzpicture}[thick,scale=0.8, every node/.style={scale=0.8},node distance=1.5cm]     \node (0) [state] {\textcolor{white}{feature extraction}};     \node (1) [cell, below of=0] {invertBotConE2\_f48\_k1\_b4\_noskip};     \node (2) [cell, below of=1] {invertBotConE2\_f16\_k3\_b4\_noskip};     \draw [arrow] (0) -- (1);     \draw [arrow] (1) -- (2);     \draw  (0.east)  [arrow]  edge [out=0, in=0, out looseness=4, in looseness=4]  (2.north); \end{tikzpicture}   0,2 are my nodes.

Intuition for groups This is quite a non-standard question, certainly for mathematics, though I believe it is no less important (for me and my peers, i.e. grads).  The course I am reading so far introduced us to Groups, rings, fields, etc. in the first year, progressing to characters, reps etc in the latter years.  However, even with representation theory I still don't feel like I have a good intuition.  How do you gain intuition in such an area. I know there will be a response of doing examples, but this doesn't really help - I've done lots already.  Am I doomed. Anyone on the Android Jelly Bean OS and not able to buy Apps/Books through wallet? I have just bought the Samsung GalaxyNote 800 and am facing this issue.   The error is (RPC:S-7:AEC-0).   What is the solution? Why is there a white space on the left side?  \documentclass{standalone} \usepackage{asymptote} \begin{document} \noindent \begin{asy} size(10cm,10cm); draw((0,0)--(100,100)); draw((0,100)--(100,0)); dot((50,50)); \end{asy} \end{document} Is there a general way to change the font of a particular symbol without switching packages?  For example, suppose I'm using Computer Modern for my entire document, but I want the "subset" operator to look as it does in mathabx.  How can I redefine it to appear in this way? Any idea what kind of tool should I but to fix the loose left crank on my bike? I found this  but not sure if it's gonna suit. Or is it enough to buy only nut driver? is a dove a "she"? how to use "he" and "she" for animals? In the song &quot;Blowing in the Wind&quot; by Bob Dylan, there's a verse that reads:  Yes, and how many seas must a white dove sail Before she sleeps in the sand?  My question is, why he used &quot;she&quot; for a dove? What about other animals and other non-humans? Is there a general rule? save as a video as .mp4 So I made an intro using animation and it saves it as a .blend and I want it so save as a video like .mp4 or something like that. I've tried changing the codec because I tried opening the intro with windows media instead of blend. I didn't try all the codec's but I tried some of them. Let's say I have a generic member in a class or method, like so: public class Foo&lt;T&gt; {     public List&lt;T&gt; Bar { get; set; }          public void Baz()     {         // get type of T     }    }  When I instantiate the class, the T becomes MyTypeObject1, so the class has a generic list property: List&lt;MyTypeObject1&gt;. The same applies to a generic method in a non-generic class: public class Foo {     public void Bar&lt;T&gt;()     {         var baz = new List&lt;T&gt;();                  // get type of T     } }  I would like to know what type of objects the list of my class contains. So what type of T does the list property called Bar or the local variable baz contain? I cannot do Bar[0].GetType(), because the list might contain zero elements. How can I do it?
