Is it possible to 'fly to location' in Leaflet in the same way as  example? How to solve "Extra junk at end of file" when using apt? I'm trying to configure some proxies for a guest virtual machine and now I'm getting:  sudo apt-get update E: Syntax error /etc/apt/apt.conf.d/95proxy:4: Extra junk at end of file   The content of the file is:  cat /etc/apt/apt.conf.d/95proxy   Acquire::http::proxy  "http://10.0.0.60:3128/" Acquire::ftp::proxy "http://10.0.0.60:3128/" Acquire::https::proxy "http://10.0.0.60:3128/" Is two-thirds plural? Is 2/3 always, sometimes or never plural?  E.g.     1a) 2/3 of the pizza were eaten.     1b) 2/3 of the pizza was eaten.      2a) 2/3 of the visitors were men.     2b) 2/3 of the visitors was men.   I feel that example 1 could go either way but example 2b sounds very wrong.  Is there a rule for this? I have created two files:  sample.txt and sample.txt  (the second file contains some hidden characters, e.g. a space). How can I remove the latest modified file? I'm using Linux. Why we can't implement AES 512 key size? Out of curiosity why we can't implement AES 512 key size?    Please explain somehow i can understand! I'm not an expert. Can someone show me a straightforward proof that  $\lim_{m\to\infty}(1+\frac{r}{m})^{mt}=e^{rt}$  Thanks! Stop suggesting Microsoft Edge browser in start menu when typing "internet" I use Chrome as my primary browser but must use Internet Explorer to be able to remote in to my work via Remote Desktop web client (since it uses ActiveX plugins). To start an app, I would often type out the name from the start menu unless I had a pinned link or shortcut handy. But if I type &quot;internet&quot; as if I were trying to start Internet Explorer, I will always be recommended Edge and have it highlighted by default.  I will never be able to use Edge here so stop recommending it... can this behavior be disabled somehow? Not even pinning the Internet Explorer link to the start menu prevents this. If I had any other shortcuts that started with the word &quot;internet,&quot; it still offers Edge and is preselected. At least if I type in &quot;chrome,&quot; Chrome is selected first. Windows 10 Pro 1909 (18363.900) Is the composition of two injective functions injective? I'm writing my final report in LaTeX for my bachelor's degree. I'm aiming at having a document similar to the .doc template used normally.   I want to have my customs headers and footers applied on pages when I'm starting a new chapter.  I'm using documentclass report with fancyhdr and lastpage packages.  My headers are defined like this:  \lhead{\myTitle} \rhead{\today} \cfoot{\thepage\ of \pageref{LastPage}}   My chapters are created using standard \chapter{title} macro.  On pages with new chapters, the only headers/footers I see is the standard page number at the bottom.  What should I do?  EDIT: I've finally gone with Peter Breitfeld's solution. I'Ve gone a step further and created my own chapter command:  \newcommand{\myChapter}[1]{     \chapter{#1}     \thispagestyle{fancy} }   Thanks for the help! In a multi server architecture, is it possible to find out from which machine a user logged into current machine using ssh?  For example, user1 logged into host1. From there, the user logged into host2 as sruser using ssh.  In above example, would it be possible to trace the sruser session of host2 back to user1 session in host1?  Would it be possible to get the hostname or terminal of user1 session? How to determine the optimal control law? Given the differential equation $$\dot x = -2x + u$$ determine the optimal control law $u = - kx$ that minimizes the performance index $$J = \int_0^{\infty} x^2 \, \mathrm d t$$  My approach was to find the state feedback $k$. But since the value of $R$ (positive semidefinite Hermitian) is not given, that means $R=0$. How do I determine the optimal control for this system where $R=0$? Unsized array declaration in a struct How to install KDE along Unity? I have just installed the latest Ubuntu 14.04 and I would like to install KDE along side my Gnome/Unity that I have now. How can I do this?  Thanks! How can I use xindy on a system with libncurses.so.6? Can I install Windows OS (Windows 7) on a removable USB hard drive? I wanted to take a sneak peek at Windows 7 so I thought of installing it. I have Windows Vista on my laptop which came pre-installed with it. I didn't want to mess with it.  So I created a partition (20 GB) in my USB external hard disk and tried to install Windows 7 on that partition. But when I booted from a Windows 7 DVD and selected the target partition on USB hard disk, it said it cannot be installed.  Is there any way to install Windows on an external USB hard disk? So I am currently making a minecraft custom map (for 1.9). I want to make the player "say" something using /tellraw commands. I did figure out how to make the player name come up using /say commands, but still have no idea how to do it using the /tellraw command.  How do I do that? OS: Ubuntu 12.04  Accidentally deleted dpkg. Now, packages can't be installed. So, needs an dpkg installer which installs packages. I am drawing some graphs with tangents. I calculated the tangent should be centered at x=57/27 which is approximately x=2.11. I'm currently using the pos and sloped keys for nodes to draw tangents, but I'm not happy about the result; the tangents don't really align.   I think this is because the pos key calculates the actual length of the graph while the graphs don't have the same length.  I'm sure I can somehow let LaTeX do the calculations for me so as to align the slopes vertically at an x value of my choice. But how?

Now, however, it still doesn't recognize heroku as a command.  It also won't show me where it is with the 'whereis' command.  But when I look in the current directory with ls -a, it shows up.  It seems to be there.   How do I install it? Redirect all subsequent commands' stderr using exec
