I have two harddisks, mounted on / and /var  I need to migrate the /var partition back into the / partition.  What are the steps required to do this?
I currently only have remote access to this CentOS box, I need to move /var form the primary RAID to a new set of disks that was installed with more space, My current thoughts on how to accomplish this is to temporarily mount the new RAID to /tmp/var. rsync everything from /var to /temp/var then modify the fstab to point /var at the new disks.  Here is my question. how do I delete the existing /var on the primary disks once I have the new disks mounted to that location (assuming this is even possible remotely)?
I have a simple cylinder which is mirrored on both the X and Y axis.  When I scale it along the X axis, the two halves of the cylinder overlap, rather than scale as it would before the mirror modifier was applied:    I haven't used Blender in a while and I know this is a simple fix. Prove $\chi(G)\chi(\bar{G}) \geq n$ for chromatic number of graph and its complement I'm hoping there's something in the same conceptual space as the old VB6 IsNumeric() function? I'm using pdfLatex (with --shell-escape option) and I had a problem of compilation with TexWorks that was successfully solved with the help of other post in this site: .  After correcting that error the code compiles smoothly but just displays the logarithmic grids, not the function. The gnuplot files are created in the right place, but the graphic doesn't come out in the PDF.  Code from :  \documentclass{article}  \usepackage{tikz} \usepackage{bodegraph}  \begin{document}  \begin{tikzpicture}[     gnuplot def/.append style={prefix={}}, % Fixed the issue (prefix was 'gnuplot/\jobname/' before) ] \begin{scope} \UnitedB \semilog{-1}{2}{-50}{60}  \BodeAmp{-1:1.35}{\POAmpAsymp{4}{2.0}+\IntAmp{1}}  \end{scope} \end{tikzpicture} \end{document}   Any clues? For example, "dude," "man," "buddy," "pal," etc, when used to stand in for someone's name.  "Hey, pal, how's it going?"  Is there a word for terms like these?  Or is "colloquialism" as close as we can get? blink code(escape code) has been removed? How many attacks can a fighter with two-weapon fighting make at 5th level? I have a 5th level fighter with the Two-Weapon Fighting fighting style.   What is the number of attacks I can make?   I say 4 attacks, but others say 3 because they say the rule on page 72 states that I get (only) 1 extra attack. Edit Mode Transparent Objects Labeling Multiple Equations Per Row of a Table I am trying to create a table with two columns of independently labelled equations (1-6). Unfortunately, everything I have found so far either has not worked or would number them as sub-equations (1a, 1b, etc).  My current attempt is:  \documentclass{article} \usepackage{graphicx, verbatim, tabularx} \usepackage{amsfonts} \usepackage{amsmath, amssymb}  \newcommand{\grad}{\vec{\nabla}}       \newcommand{\prtl}[2]{\frac{\partial #1}{\partial #2}}  \newcommand{\curl}{\grad\times} \begin{document}  \begin{tabular}{p{5cm}p{5cm}}  $\curl\vec{E} = -i\omega\mu\vec{H}$ &amp;   $\curl\vec{H} = i\omega\mu\vec{E}$ \\  \begin{equation}  \label{eq:curlHx}   \prtl{E_z}{y} +\gamma E_y= -i\omega\mu H_x  \end{equation}  &amp;  \begin{equation}  \label{eq:curlEx}    \prtl{H_z}{y} +\gamma H_y= i\omega\mu E_x  \end{equation}\\  \begin{equation}  \label{eq:curlHy}    -\prtl{E_z}{x} -\gamma E_x= -i\omega\mu H_y  \end{equation}  &amp;  \begin{equation}  \label{eq:curlEy}    -\prtl{H_z}{x} -\gamma H_x= -i\omega\mu E_y  \end{equation}  \\  \begin{equation}  \label{eq:curlHz}   \prtl{E_y}{x}-\prtl{E_x}{y} = -i\omega\mu H_z  \end{equation}  &amp;  \begin{equation}  \label{eq:curlEz}    \prtl{H_y}{x}-\prtl{H_x}{y} = -i\omega\mu E_z  \end{equation}  \end{tabular}  \end{document}   Is there an environment other than tabular that would make this work? Tabularx came close (got the numbering correct), but the formatting/spacing was horrific. How do I make Panel always transparent like the Dock in GNOME 3? I'm using Ubuntu 17.10. I want the Panel to be always transparent instead of dynamic transparency. A shrinking map that is not a contraction no fixed point. Working from Munkres.  Show that $f: \mathbb{R}\to \mathbb{R}$ given by $f(x) = [x+\sqrt{(x^2+1)}]/2$ is a shrinking map that is not a contraction that has no fixed point.   I figured out the fixed point part but have no clue how to show the other part.  For the fixed point part $$f(x) = x \Leftrightarrow x = [x+\sqrt{(x^2+1)}]/2$$  then $$2x = x + \sqrt{(x^2+1)}$$ $$x = \sqrt{(x^2+1)}$$ $$ x^2 = x^2+1$$  Which is a contradiction.   Thanks in advance. I created a custom counter 'rtaskno' and a command '\rtask' as following:  \newcounter{rtaskno} \newcommand{\rtask}{%    \stepcounter{rtaskno}%    \thertaskno}   I like to use them as following:  \section{Task \rtask. Blah Blah..}  \section{Task \rtask. Blah Blah..}  \section{Task \rtask. Blah Blah..}  \section{Task \rtask. Blah Blah..}   Later in the text, if I want to cross-reference 'Task 3', how can I do it? Where to put label? I'm new to blender and trying to model the blade of my helicopter and can't figure out how to make an edge curved (for the red tip and selected edge). The object is a plane, with one loop cut. I attempted making a bevel Ctrl B, but nothing happens (A dotted line appears attached to the cursor, moving does nothing, left-clicking does nothing).  also I cant add a curve modifier, just says its disabled. What is the correct way to model this? I am trying to run a simple echo script via crontab. I set that to run every minute, but it doesn't give output on shell screen.

When working with views and view controllers in an iPhone app, can anyone explain the difference between loadView and viewDidLoad?    My personal context, is that I build all my views from code, I do not and will not use Interface Builder, should that make any difference.  I've found that often when I add init code to loadView, I end up with an infinite stack trace, so I typically do all my child-view building in viewDidLoad...but it's really unclear to me when each gets executed, and what is the more appropriate place to put init code.  What would be perfect, is a simple diagram of the initialization calls.  Thanks! Black screen when creating movie I've rendered about 300 frames for a short clip. The frames look fine, but when I compile into a movie all I get is a black screen. I haven't been able to find anything to solve this problem. The individual frames are well lit, capture what I want them to, look great. Just creating the AVI or MPEG results in a clip that has nothing but black. How to create a Facebook page without a personal account In the past, Facebook used to let business create pages or apps without a personal account. This account created in the page/app creation process had limited capacities and could be switch to a full personal account after—if needed (irreversible).  But today, if I want to create a page for a new brand, without having a Facebook account, it seems I can’t anymore. And I can’t find any communication from Facebook regarding this change.   Anybody has any info? Is it still possible (in a new way maybe)? What is the difference between therapy and treatment? How general is the Lagrangian quantization approach to field theory? It is an usual practice that any quantum field theory starts with a suitable Lagrangian density. It has been proved enormously successful. I understand, it automatically ensures valuable symmetries of physics to be preserved. But nevertheless the question about the generality of this approach keeps coming to my mind. My question is how one can be sure that this approach has to be always right and fruitful. Isn't it possible, at least from the mathematical point of view that a future theory of physics does not subscribe to this approach?
