Create directory if it does not exist "Improve" treated as improper response to proper response to audit Let $M$ be the space of all $m\times n$ matrices. And $C=\{X\in M|rank(X)\leq k\}$ where $k\leq \min\{m,n\}$. How to proof that C is a closed subset of M? Regarding the recalc in question rep increase what happens due to the cap? When the recalc runs what happens regarding rep capping on particular days? Say I earned 200 solely from questions on one day, will I earn a further 200 when the recalc runs or will I earn zero?  On a similar note if I got no rep from a question upvote on a day will the recalc give me 10, 5 or 0 rep? How can I remove duplicate values from a multi-dimensional array in PHP?  Example array:  Array (     [0] =&gt; Array     (         [0] =&gt; abc         [1] =&gt; def     )      [1] =&gt; Array     (         [0] =&gt; ghi         [1] =&gt; jkl     )      [2] =&gt; Array     (         [0] =&gt; mno         [1] =&gt; pql     )      [3] =&gt; Array     (         [0] =&gt; abc         [1] =&gt; def     )      [4] =&gt; Array     (         [0] =&gt; ghi         [1] =&gt; jkl     )      [5] =&gt; Array     (         [0] =&gt; mno         [1] =&gt; pql     )  ) Now the cubs are growing, fed on mom's milk, but mom herself hasn't eaten in five months, and is getting thinner by the day.   What does in mean here, and how would the meaning of that piece change if for were used? piping in real time This is more a conceptual thing than a current problem.  Would it be possible to do this:  tail -f &lt;file&gt; | grep "string" | sed 's/stuff//g' &gt;&gt; output.txt  The problem I'm thinking is that tail -f never terminates so it won't progress in the command. I'm trying to read and output a file in real-time. If this doesn't work how would I do it? Can I store my pixels somewhere so I don't lose them when I die? I die all the time. My pixel balance hovers around zero as a result. I'm trying to save up for armor but my nonstop deaths are making that difficult.  Is there anywhere I can store my pixels so that when I die, I won't lose a bunch of them? Python does not find packages installed without Anaconda I'm trying to install kivy for python 3 using apt-get:      sudo apt-get install python3-kivy   And it is installed in      /usr/lib/python3/dist-packages   But, when I tried to load it in python, I get a ModuleNotFoundError      Python 3.6.3 |Anaconda custom (64-bit)| (default, Oct 13 2017, 12:02:49)      [GCC 7.2.0] on linux     Type "help", "copyright", "credits" or "license" for more information.     &gt;&gt;&gt; import kivy     Traceback (most recent call last):       File "&lt;stdin&gt;", line 1, in &lt;module&gt;     ModuleNotFoundError: No module named 'kivy'   When I check the system path from python, I only get packages in Anaconda:      &gt;&gt;&gt; import sys     &gt;&gt;&gt; print('\n'.join(sys.path))      /home/santiago/anaconda3/lib/python36.zip     /home/santiago/anaconda3/lib/python3.6     /home/santiago/anaconda3/lib/python3.6/lib-dynload     /home/santiago/anaconda3/lib/python3.6/site-packages     /home/santiago/anaconda3/lib/python3.6/site-packages/torchvision-0.2.0-py3.6.egg   Is there any way to include the '/usr/lib/python3' path to Anaconda?  Thanks. Example images in LaTeX? How to make an example image in LaTeX, a dummy image, a spot holder? I have seen it before, but I can't remember how they would made. It would be nice to be able to use example images - if you should help anyone or you need to question in this community. You might say I could , but I tried - and are obviously too stupid to find anything.  \documentclass[12pt,a4paper]{article} \usepackage[utf8]{inputenc} \usepackage[ngerman, danish]{babel} \usepackage[T1]{fontenc} %\usepackage[]{}  \begin{document}  \iffalse \begin{figure} \includegraphics[scale=1]{•}  \end{figure} \fi  \end{document}   Is it also possible to resize the example image? So I need a usepackage to make an image without including an immage. An placeholder so anyone can try my code without needing images - just needing my tex-code. I hope you understand?  Kind regards! Opening Ubuntu 20.04 Desktop on WSL2 I installed Ubuntu 20.04 (server/terminal) from the Windows 10 app store, and then after launching the Ubuntu Terminal via WSL2 (Windows Subsystems for Linux) , I installed Ubuntu Desktop and did several steps to try and get a desktop instance of Ubuntu 20.04 launched.  In short, the steps involved editing the .bashrc file, installing Xming, and then attempting to open the Ubuntu desktop in Xming with the &quot;startxfce4&quot; command.  However, &quot;startxfce4&quot; just doesn't open the desktop for me.  I can get programs to open with &quot;grun&quot; and the file explorer to open with &quot;gopen&quot; though, so it is working partially. Does anyone have any alternative suggestions to how I might get the terminal to open up the full Ubuntu Desktop?  Obviously, this wasn't what Windows had in mind with WSL2 so this is kind of a reach, but any input would be helpful.  Could I somehow do this from the file explorer or with a program that could opened from &quot;grun&quot; or &quot;gopen&quot;? How can I limit ssh *remote* port forwarding? I need to limit which ports can be remotely 'ssh -R' forwarded by an user.  I know about permitopen option on authorized_keys, but as it says on man page it only limits local 'ssh -L' port forwarding  As discussed  a user would get the same with netcat or similar, but in this case user has no shell access  I also found  that talks about using selinux or LD_PRELOAD, but I never configured selinux before and can't find info on how to do that with LD_PRELOAD.  maybe someone have made a patch for openssh to implement that?  EDIT: I've found  so I guess it's not yet implemented As per c99 standard, size of long long should be minimum 64 bits. How is this implemented in a 32 bit machine (eg. addition or multiplication of 2 long longs). Also, What is the equivalent of long long in C++. When clicking between "Week", "Month", "Quarter", "Year" and "All" on the users page, the name I have typed in to filter on disappears. I feel like it should stay there, so that I can type in my name, and see how I've done in a week/month/etc. White space below footer get value part of specific word in AIX want to search string and need part of string  file.txt:  CREATE MULTISET TABLE $$ENV$$_TEMP_ESM.EMPASGMTAMPTMPRTRSE, NO FALLBACK ,      NO BEFORE JOURNAL,      NO AFTER JOURNAL,      CHECKSUM = DEFAULT,      DEFAULT MERGEBLOCKADSRATIO   while using below sed command getting extra value  Output:   bash-4.3$ sed -n 's/.*$$ENV$$_//p' file.txt  **TEMP_ESM.EMPASGMTAMPTMPRTRSE** ,NO FALLBACK ,   I need only TEMP_ESM.EMPASGMTAMPTMPRTRSE poll() failed, context incorrect? - Example: bpy.ops.view3d.background_image_add() Problems after upgrading to 14.04 (only background and pointer after login) Faction Membership Limits in Fallout 4 Are there any limitations to the faction memberships you can have in Fallout 4?  I'm brand-new to the Fallout universe, and just got to the point of being invited to the Brotherhood of Steel. However, I'm a bit concerned about their politics and how it may affect my standing with other factions I may encounter.  If I join the Brotherhood, will there be other factions that I can't join? Are there any other factions that have such limitations?  Note: I'm still not very far into the game, and not very familiar with the Fallout 4 universe in general, so please make liberal use of spoiler markdown in your answers. Essentially, the only things that need to be un-spoilered are Yes/No answers for the questions asked above. Moving an already-running process to Screen My office job routinely sees me connected to a Linux box via VNC.  Sometimes I start a remote job on the console, and realize later that it runs much longer than expected. (Should have started that one under Screen in the first place...)  I don't want to keep my workstation running overnight just to keep the VNC session open; I would like  to move that already-running remote job into a Screen session (on the remote box), so I can power down the workstation (and reconnect next morning).  How can this be done, if at all?
