I've set the / volume for 30gb and it's getting full now. I want packages and programs to be installed in /home partition and I don't know how.  I want to install things into my /home partition!!
I do not want packages to be installed under /. (sudo apt-get install ...).   The reason why I need to do this is that:  My '/' is mounted with my SSD(16GB) and my hard disk(500GB) is mounted at '/home'.   I have already installed my Ubuntu 12.04 on that SSD. There is not much free space under '/' now.
Integral of $ 1 \, / \, (1 + a \, \cos(x) )$ Compiling with either XeLaTeX or LuaLaTeX, \emph{} no longer displays text as expected, i.e. in italics. \textit{} works fine. Here is a MWE demonstrating the issue.  \documentclass{article}  \usepackage{fontspec}  \begin{document}      \emph{lorem ipsum}      \textit{lorem ipsum}  \end{document}   Here is the output I get :   I have TeXLive 2016 (MacTeX) installed. I updated it an hour ago with sudo tlmgr update --self --all.  I guess there is something wrong but what ? I'd be happy to have some help. Thank you. How to wait in bash for several subprocesses to finish and return exit code !=0 when any subprocess ends with code !=0? How to wait in a bash script for several subprocesses spawned from that script to finish and return exit code !=0 when any of the subprocesses ends with code !=0 ?  Simple script:  #!/bin/bash for i in `seq 0 9`; do   doCalculations $i &amp; done wait   The above script will wait for all 10 spawned subprocesses, but it will always give exit status 0 (see help wait). How can I modify this script so it will discover exit statuses of spawned subprocesses and return exit code 1 when any of subprocesses ends with code !=0?  Is there any better solution for that than collecting PIDs of the subprocesses, wait for them in order and sum exit statuses? The title kind of says it all. Is it possible to replace C# with C++ on a game using Unity? I am sketching out my 2012 programming project, and Im planning to make a classic fantasy RPG game.  The world design, plots, characters and all that I can make, but being a avid tabletop role-player, I would love to use a stable and tested rpg system like Pathfinder, since its balanced and interesting.  Would there be a problem if I make a game (indie dev, but still planning on selling it) using the pathfinder license ? Do I have to purchase a license? And would I able to say that it's based on the Pathfinder ruleset, or should i keep that under wraps.  All big official D&amp;D games boast with that they are official, so doesn't this mean that unofficial games can exist too ?  It's not because I wan't to jump the lowest fence, and all storylines and the game setting will be by my own hand. But I love the Pathfinder system and actually think it could use some publicity as well.  If not, I guess I could make a Pathfinder-like system, with a few measely differences... But I would rather not, since it would feel a bit of a rip... How do I fix my locale issue? Born's Rule, What is the Reason? Launch Debian and Windows Cooking away alcohol When you cook with wine or spirits, when does the alcohol cook away? Obviously high temperatures will do it, but how low of temperatures will work? Also, does it vary by the type of alcohol? In what order should one apply max HP reduction and damage? A character at 10/26 HP is hit by a Wraith and fails the Constitution saving throw. They take 21 damage and their maximum HP is reduced to 5.  Are they unconscious because the 11 excess damage is less than 26 or dead because it's greater than 5? How to switch from Natbib to Biblatex in pre-made document class/template? I am using  to write my thesis. The template uses Natlib for references, whereas I really need Biblatex.

Natlib seems to deeply rooted in the file and I don't know how to change it/access the settings/the ".sty"-file. Can I use the example documentclass combined with biblatex (instead of the standard natbib) without losing the great parts of the rest of the document class?  Thanks very much :) Why are my Elytra Wings are not activating? Is there a difference between installing an application via Ubuntu Software Center or a terminal? I would like to ask a very basic question but I have never thought about it before. Well, when someone installs an application from terminal, he has to add the repository first, right? On the other side, when someone installs an application from the Ubuntu Software Center, is the repository then added automatically?  I am asking those questions to figure out this: When I run update and then upgrade, will this application be upgraded or not? Is the result same in two options? Prove that $f\in L^1(A)\Leftrightarrow \sum_{n}^{\infty}m(\{ x\in A : f(x)\geq n \}) < \infty$ Is there a geometrical method to prove $x<\frac{\sin x +\tan x}{2}$? Suppose $x \in (0,\frac{\pi}{2})$ and we want to prove $$x&lt;\frac{\sin x +\tan x}{2}$$I tried to prove it by taking $f(x)=\sin x+ \tan x -2x$ and show $f(x) &gt;0 ,when\space  x \in (0,\frac{\pi}{2})$ take f'$$f'=\cos x +1+\tan ^2 x-2\\=\tan^2 x-(1-\cos x)\\=\tan ^2 x-2sin^2(\frac x2)$$ I get stuck here ,because the last line need to be proved $\tan ^2 x&gt;2sin^2(\frac x2) ,when\space  x \in (0,\frac{\pi}{2})$ $\bf{Question}:$ Is there a geometrical method to prove the first inequality ?

As someone supervising postgrad students, I wonder what is the best way to train these students to write high-quality research papers?    The best way seems to be through coauthorship but ...  On the one hand I can be hands-off and rather give them feedback as best as I can but let them do most of the work themselves, sort of like a "sink or swim" strategy.  On the other hand I can be hands-on and rewrite the paper (or large parts of it) and hope that they learn from the example I give.  On the one hand I want them to learn to write papers without me some day and I want them to learn as quickly as possible to take load off me.  On the other hand I want us to publish in the best place possible with as little stress as possible.  On the one hand I want them to see the peer review comments from what they themselves have written.  On the other hand I do not want them to be discouraged by the peer review system early on and do not want to submit papers I know we could have written better.  On the one hand I want them to get confidence by being published and presenting work at good venues.  On the other hand I wonder if they need to get there themselves to get that confidence boost.    At the moment I'm very hands on. There's a few factors for this: I don't like submitting papers that are not up to a certain standard, I'm a native English speaker in a non-English speaking country with non-native speaking students, publications are a high priority for me, etc.  But recently a friend/colleague warned me that I should not be so hands-on with the writing of the papers of my students. He pointed to recently graduated researchers in my area that published good work as students but who struggled after leaving their PhD supervisor saying their supervisor did them no favours in the long term ... that by being so hands on, while the students have success getting published and so forth with me, I'm not really doing the most important thing a good supervisor should do: making myself obsolete.    My question is how to train students to write good research papers and in what ways can I balance being hands-on and hands-off?  I'm also interested in methods not directly involving coauthorship. Leg bisectors in a trapezoid and angle equality Let $PQRS$ be a trapezoid. The bisectors of legs $PS$ and $QR$ intersect the opposite legs at $M$ and $N$ so that triangles $PMS$ and $QNR$ are formed.  Prove that $\measuredangle PMS= \measuredangle QNR$.  The question may seem easy but I fail to move on, playing with angles didn't help. I'd appreciate some hint from somebody with an eye for geometry and triangles.
