How do I allow long URLs to have line breaks at any point. This is in the bibliography not the main text. I am trying to save space so don't want extra spaces to be added to make it only break at slashes, for example, as it does by default.  I am using biblatex+biber. I am a Bangladeshi citizen. Back in 2013, I went to India with a tourist visa and overstayed for four days. It was due to a gout attack in my feet but I don't have my medical papers to prove that.  I applied again in 2015 for a visa, at Dhaka, and they refused my visa and blacklisted my passport, writing some numbers and date on it. Now I am not able to get an Indian visa.  How I can remove my passport from the blacklist and get a new Indian visa? Do I need a Indian immigration lawyer to do this? Update to Windows 10: What is going to happen to my data and apps? I have Windows 8.1 Update, if I update to Windows 10 when it becomes available what is going to happen to my data and apps?  Of course I have to do a backup, but I wonder if the data will be overwritten or not. How is prototyping done in a professional EE environment? Do you do your prototypes on breadboards, on copper clad boards, Manhattan style, or do you just draw schematics, order PCBs made and assembled and work with them, hacking here and there if necessary? Story where vampires are created by drop absorbed on neck? Do the topologies with the same convergent sequences coincide? Do the same sequential convergence in two topologies the result are the same topologies? Let $X$ be topological  space with topologies $\tau$, $\tau'$. Let $(x_{n})\in X$ and $x\in X$ and $(x_{n})\rightarrow x$ with $\tau$ if and only if $(x_{n})\rightarrow x$ with $\tau'$. Do the two topologies on $X$ coincide? Can Jupiter be ignited? Our solar system itself contains two candidate "Earths"  One is Jupiter's moon Europa and another is Saturn's moon Titan. Both of them have the problem of having at low temperature as Sun's heat cannot reach them.    Jupiter is made up mostly of Hydrogen so is our Sun. Can we ignite Jupiter so that it will produce enough heat to warm these two earth like planets/satellites? What can be consequences of any of such attempt?

Movie: Creature crawls out of its current hosts mouth into next hosts mouth How to make terminal autocomplete when there are several files/directory? If I have several directories, like:  afoo abar   sometimes my terminal will refuse autocomplete when I press tab (e.g. "cd a" then tab), and print the list of directories instead. Sometimes it even throws a noisy, annoying sound. Any idea how to make it autocomplete in cases like this? E.g it can show abar first, and then afoo if I press tab again. I saw this is the case in windows, or some applciation in Ubuntu How to send variable to an inline shell-script? 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? Floor a date in SQL server In SQL Server, how do I "floor" a DATETIME to the second/minute/hour/day/year?  Let's say that I have a date of 2008-09-17 12:56:53.430, then the output of flooring should be:   Year:  2008-01-01 00:00:00.000 Month: 2008-09-01 00:00:00.000 Day: 2008-09-17 00:00:00.000 Hour: 2008-09-17 12:00:00.000 Minute: 2008-09-17 12:56:00.000 Second: 2008-09-17 12:56:53.000 Simple examples of uncorrelated but not independent $X$ and $Y$ Any hard-working student is a counterexample to "all students are lazy".  What are some simple counterexamples to "if random variables $X$ and $Y$ are uncorrelated then they are independent"? Can't execute terminal commands: "the command 'sudo' is available in '/usr/bin/sudo'" Why does tmux set TERM variable to screen? Citing tmux man page:  The TERM environment variable must be set to “screen” for all programs running inside tmux.  New windows will automatically have “TERM=screen” added to their environment, but care must be taken not to reset this in shell start-up files.  Is this this because tmux session can be attached to any terminal (e.g. remote), screen being lowest common denominator? If I know my terminal, can I force it without unexpected results, or would some unsupported capabilities break (like scrolling)? Let $\ln X \sim \operatorname{Exp}(1)$ and $X,Y$ i.i.d.  What is the distribution of $Z=XY$?  My attempt: $$P(Z\le z)=P(XY\le z)=P(\ln(XY)\le \ln(z))=P(\ln(X)+\ln(Y)\le \ln(z))$$  We need the convolution, since $\ln X $ and $\ln Y$ are independent we get, $$\int_0^{\ln(z)} f_{\ln(X)}\circledast f_{\ln(Y)}=\int_0^{\ln(z)}e^{-y}e^{-x+y}\,dy=e^{-x}ln(z),$$ i.e. $e^{-x}\ln(z)$ is the density of $XY$ Biblatex: URL-breaking not working in DVI-mode I'm preparing my bibliography and noticed that biblatex-printbibliography produces Overfull \hbox several times.  Examples (gray lines indicates text margins, red line is the physical page margin):        Why is hyperref line-breaking not working as expected using pdflatex or even latex -&gt; dvipdfm BUT not using latex -&gt; dvips -&gt; ps2pdf?  Also it would be great if someone could point out how I can raise the indentation of the second (and following) lines, as this might look better.  edit: Customized question, as the answer given by lockstep solved the third problem. The second problem seems to be identical to the first.  \documentclass[12pt]{scrbook} \usepackage[english]{babel} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage[ps2pdf]{hyperref} %\usepackage[ps2pdf,breaklinks=true]{hyperref} %This doesn't change anything. %\usepackage{breakurl} %That makes no difference either.  \usepackage[a4paper,twoside,showframe]{geometry} %show text margins  \usepackage[style=alphabetic,backend=biber,maxnames=4,minnames=3,maxbibnames=99]{biblatex} \bibliography{biblatex-issue}  \begin{document} \nocite{*}  \printbibliography[heading=subbibliography,type=article,prefixnumbers={A-}] \printbibliography[heading=subbibliography,type=book,prefixnumbers={B-}] \printbibliography[heading=subbibliography,type=online]  \end{document}   And the bib-file:  @online{GLS:datasheet,     title         = "GLS Datasheet",     organization  = "Optoelectronics Research Centre",     howpublished ="Website",     date = "2004-09",     urldate="2013-07-01",     url ="http://www.southampton.XXXX",     address       = "Southampton, United Kingdom" } @book {Lifante:Fundamentals,     title = "Integrated Photonics: Fundamentals",     author = "Lifante, Ginés",     publisher = "J.Wiley",     address = "Chichester",     year = "2003",     type = "text",     isbn = "9780470848685" } @article{Labadie:First_fringes,     author = {Labadie, L. and Mart\'{\i}n, G. and Anheier, N.
