install python packages for qgis?
Installing 3rd party python libraries for QGIS on Windows
Is it possible to remove a terminal command? For example, if there was a command call lookup (not an alias), how would I go about removing it? A proof that $1=2$. May I know why it’s false? When I upgrade from one version of Ubuntu to the next, the upgrade tool rightly disables all my PPAs, so that software compiled for or otherwise tied to the old version of Ubuntu does not interfere with the new version that I just upgraded to.  Is there any way to automatically re-enable and update any PPAs that provide packages for the new version of Ubuntu? For example, suppose I'm currently running Maverick, and I have two PPAs enabled, "foo" and "bar". Suppose that "foo" provides packages for both Maverick and Natty, while "bar" provides packages for Natty only. Is there a tool I could run after updating to Natty that would re-enable my "foo" PPA and update it to point to the Natty packages, while leaving the "bar" PPA disabled? How to clone a Legendary permanent? I want to clone  without falling prey to the legend rule and without using . Are there any cards that allow you to copy a card's text without copying its name? I was unable to find any but might have failed to search the right wording. One-dimensional vector space and it's subspaces I'm trying to do something similar to this epsilon-delta graph I've found.  Specifically, I'd like to copy the placements and arrows, like the L+e and L-e coming out of L. Same thing with the x0 + d and x0-d coming out of the x0. Can someone help me with this? This is what I have so far.    \begin{tikzpicture} \begin{axis}[ ,         legend pos=north east,         axis x line=middle,         axis y line=middle,         x tick label style={/pgf/number format/fixed,                             /pgf/number format/fixed zerofill,                             /pgf/number format/precision=1},         y tick label style={/pgf/number format/fixed,                             /pgf/number format/fixed zerofill,                             /pgf/number format/precision=1},         grid = major,         width=8cm,           height=6cm,         grid style={dashed, gray!30},         xmin=0   ,     % start the diagram at this x-coordinate         xmax= 4,    % end   the diagram at this x-coordinate         ymin= 0,     % start the diagram at this y-coordinate         ymax= 11,   % end   the diagram at this y-coordinate %axis background/.style={fill=white},         xlabel=$x$,         ylabel=$f(x)$,         tick align=outside,         enlargelimits=false] % plot the stirling-formulae %\addplot[domain=0:200, red, ultra thick,samples=100] {K/(1 +    ((K-X0)/X0) * exp(r*x))    }; \addplot[domain=0:200, red, ultra thick,samples=100] {3*x-1 };  \addplot[line width=1pt, dashed, mark=none, black] coordinates {(0,8) (3,8)}; \addplot[line width=1pt, dashed, mark=none, black] coordinates {(3,0) (3,8)}; \addplot[line width=1pt, dashed, mark=none, blue] coordinates {(3.33,0) (3.333,9)}; \addplot[line width=1pt, dashed, mark=none, blue] coordinates {(2.666,7) (2.666,0)}; \addplot[line width=1pt, dashed, mark=none, blue] coordinates {(2.666,7) (0,7)}; \addplot[line width=1pt, solid, mark=none, blue] coordinates {(3.333,9) (0,9)}; \addplot[holdot] coordinates{(60,8.66)};  % 1\addlegendentry{$f(x) = 10 \sin (x)$}  \end{axis}   \end{tikzpicture}   which gives Within a custom command, I'm doing the following to write to a file:  \newcommand\mycommand[1]{   \newwrite\file   \immediate\openout\file=foobar.tex   \immediate\write\file{     foo     bar     #1     blarg   }   \immediate\closeout\file }   Of course when I invoke it as \mycommand{baz}, I get the following contents in foobar.tex:  foo bar baz blarg   with all new lines turned into spaces by LaTeX. My question is, is there a way to output these lines into the file "as expected", i.e. with real new lines at the end of each line instead of a space? I'm thinking some \catcode wizardry should do the trick, but I'm not sure which character I need to redefine and to what category code.  Update  The solution in  works perfectly. The only problem is when #1 contains embedded newlines. I can of course send it to mycommand with its own slew of ^^J, I was wondering if there is a way to avoid this. I've bought a  to use with my EOS 200D and while I love the wide aperture, it appears to be quite difficult to achieve sharp focus on people's faces when shooting at f/1.8. I've tried both using Dual Pixel focus in Live View and using the center focusing point in the viewfinder, but it doesn't get me perfect results.  Is this simply a characteristic of cheap wide-aperture lenses? Or is it impossible to get sharp focus with a fully open aperture?  When I'm at at home using a tripod and focusing on a still subject I do get good focus (so it's not a camera or lens issue). But it's hard to do with people who are slightly moving between shots. I am taking my first dive into testing a mobile app.  It will be available to iOS and Android.  I've been searching for a way to test and automate iOS without having an actual iPhone or any other Mac device.  We run Windows here at the office.  I was looking to use iPhone emulators but it doesn't seem possible.  I saw Appium Studio/SeeTest but it seems even that requires iTunes and a real device.  I know you can set up a Mac vm on a Windows machine but are there any other ways to test iPhone without having to do this? What is the proof that a force applied on a rigid body will cause it to rotate around its center of mass? A finite group which has a unique subgroup of order $d$ for each $d\mid n$. Why didn't the mirror universe's tech progress past the main timeline's? In Star Trek TOS, we see the Defiant disappear to unknown parts  ('The Tholian Web'), and Star Trek: Enterprise revealed that the Defiant went back in time to the mirror universe ('In a Mirror Darkly', parts 1 &amp; 2).   Because of this, one might wonder why (in-universe) the mirror universe didn't obtain (and maintain) technological superiority over the main timeline. (Granted, the out of universe answer is that TOS depicted the two universes as having essentially the same level of tech)  So does any work (whether STO, or a pocket books work) address why the mirror universe didn't simply leap frog the main universe's technology?   (Or to put it another way, why did the mirror universe's technology appear to stagnate for a century after obtaining access to the Defiant's advanced technology?) What's the best order to read HP Lovecraft's novels? I've always been interested in the Cthulhu mythos and I wanted to get into HP Lovecraft's books. What is the best book to start with? I know that Cthulhu was first mentioned in Lovecraft's Call of Cthulhu in 1928. Is that the best book to start with? Should I just start reading Lovecraft's books from his first publication onward? Does Microsoft Office 2010 have version control?  In other words, does it automatically save old versions of files? Still alive, still alive after kill -9 / SIGKILL An apache2 process got stuck on my server and caused problems with other services.

D    Jun27   0:00 /usr/sbin/apache2 -k start   Naturally, I killd it. it's still alive. so I kill -9d it. It's still "alive".  Now this is where the question gets serverfault/unix&amp;linux-worthy: Is there a way to get port 443 back without doing the obvious thing: rebooting? Iptables is installed.  Update: I could not resolve the Problem withouth rebooting. The general approach (use lsof or /proc/$PID/fd to find out which and get rid of that drive) as described here and in the "duplicate" could well have worked if not for additional (probably) hardware defects. Can I cast a Warlock spell with another (higher) spell slot from a different multiclass? Reviewing an answer to a recent question I posted, I had a thought about Armor of Agathys. In the event of a Sorcerer 18 / Warlock 2 build, would the character be able to cast Armor of Agathys with a 9th level spell slot, thus getting 45 Temporary Hit Points and dealing 45 damage when hit?   Is the spell in any way limited to being cast using Warlock spell slots or to a maximum of a 5th level spell slot? Please provide me with the guidance to install oracle 11gr2 on Ubuntu 14.04. Is there a way to find self-answers with the advanced search? Preferably, not using the  and including results of all time and not just the recent ones with the new share your knowledge, Q&amp;A-style Why is the $S_{z} =0$ state forbidden for photons? I've been looking around and I can't seem to find an automatic (i.e. buzz- or Twitter-like) way to follow users inside Stack Exchange. Why haven't the developers added such a feature? It could help beginner users follow other beginners with the same interests. We would be able to learn from each others' questions and pitfalls. Also, it would reduce double posting.
