How to monitor disk activity? How do I view my Disk Activity on Ubuntu? For example, How can I monitor what is being written and read from disk as well as the percentage of disk usage?  I am looking for an application similar to the Resource Monitor in Windows. Is it Possible to Disable Feed and Topics for an Object Completely at Profile Level / Page LayOuts I have a content type with multiple fields. Some of the fields are accessible to everyone and there are other fields for which the access is controlled.   Example: There is a content type called Reports with fields like title, summary, body etc. Title and summary should be visible to everyone but the access to body field is controlled.  For implementing this I need to have 2 view modes. one of them will have the fields title and summary displayed with the rest of the fields hidden. The other view mode will have only the body field visible. I am planning to implement the hook hook_node_access to derive the access permissions for the node. So how can I get the view mode in this hook so that I can have my access check based on the view mode. How to Change the Origin when moving a Collection Instance I have created an Collection Instance, when I try to move it, the origin(to snap at vertices or edges) is far away from the object, I want to set it.    In the image, the Collection Instance is selected, the cross is far away from the object and I can´t set it using "Set Origin to 3D Cursor"  What Am I missing? Ubuntu 18.04 No WiFi adapter found [Dell Inspiron 3542.] Does the curvature of spacetime theory assume gravity? Whenever I read about the curvature of spacetime as an explanation for gravity, I see pictures of a sheet (spacetime) with various masses indenting the sheet to form &quot;gravity wells.&quot; Objects which are gravitationally attracted are said to roll down the curved sheet of spacetime into the gravity well. This is troubling to me, because, in order for objects on the locally slanted spacetime sheet to accelerate, gravity must be assumed. Therefore I ask; does the explanation of gravity as the curvature of spacetime assume gravity? If yes, what is the point of the theory? If No, what am I missing? i Need a batch file to create a folder "test" in every removable device than i plug in my computer (pendrives and etc)  i am trying something like this  set "extDrive=" for /f %%D in ('wmic volume get driveLetter^ where drivertype=2 ) do set extDrive=%%D mkdir "%extDrive%\test"   Someone can tell me why this is not working ?? The speed of light as it approaches a massive body No matter how fast you go, you will aways perceive the speed of light as constant. Taking that as a fact, the special relativity theory was formulated. Now, for what I understand about general relativity, just by standing here on the surface of the planet under the effect of gravity, my frame of reference is a little different from someone in geostationary orbit, and time goes by a little slower for me.  So, considering me and someone in geostationary orbit, does both of us would perceive light at the same speed? If so, does that means that the light is slower down here than up there? What do you feel when crossing the event horizon? Let $f$ be a real, continuous function defined on $[0,\infty)$ such that $xf(x)$ is increasing for all sufficiently large values of $x$. Show that if   $$\int_0^x f(y)\,dy \sim Ax^\alpha \quad \left(\,x\to \infty\right)$$  for some positive constants $A$ and $\alpha$, then  $$f(x)\sim \alpha Ax^{\alpha -1} \quad \left(\,x\to \infty\right).$$  Clearly, I have to use differentiation somewhere, but I don't know how to manipulate $\lim_{x\to \infty}\frac{\int_0^x f(y)\,dy}{Ax^\alpha}=1$ to get the desired result.  From suggestions given, I know that by L'hospital's rule, it's enough to show that the limit $\lim \frac{f(x)}{\alpha Ax^{\alpha -1}}$ exists, and this limit equals $ \lim \frac{xf(x)}{\alpha Ax^{\alpha}}$. From here, I'll need to use the given assumption that $xf(x)$ is eventually increasing. But how can I show the existence of the limit based on these facts?  I would greatly appreciate any solutions, hints or suggestions. Does the Google spider render JavaScript? Why there isn't any integer solutions in non-zero integers for $z^3 = 3(x^3 +y^3+2xyz)$? Consider the following Diophantine equation  $$z^3 = 3(x^3 +y^3+2xyz)$$  Is there any elementary proof for the non-solubility in non-zero integers for this  Diophantine equation, where the absolute value of $x, y$ and $z$ are pairwise coprime integers?  I have proved the impossibility of solution of this Diophantine equation in non-zero integers, but that took quite a few pages and I consider this too long. I hope for a much more elementary and shorter proof for this puzzle.  Hint: It should be noted that is also true for the non-availability of the similar form (replacing coefficient 3 by 1) as the following:   $$z^3=x^3+y^3+2xyz,$$ but this case is very simple to prove, where $x, y\;\&amp;\; z$ are nonzero integers. iPhone Storage Space Inaccuracy (No Storage Space) Webform redirect I'd like to do something pretty straightforward: After user fills out a , I'd like a button that simply redirects them to a URL (in this case it's to a demo sandbox). Of course I'd want the user to fill in their info to capture for lead-generation purposes. My  is set up correctly in that it correctly captures all the user fields and submits them to me via email. However, upon completion "click" I'd like to have the user redirected to a determined internal URL www.mysite.com/foo  I can't figure out how this is done with the vanilla webform settings. Am I missing something obvious? How do I get the  value of a character as an int in ? I know than an ellipsis can be used to show a broken sentence, the same way an em dash can be used. What I don't know is that if the two are interchangeable and it is writer preference or if different meaning is conveyed by their use.  Are ellipses and em dashes commutable? Show $\lim \limits_{n \to \infty} \frac{a_{n+1}}{a_n} = \|f\|_{\infty}$ for $f \in L^{\infty}$ I have a question that I need help with getting started (possibly I would be back for more help).     I have a measure space $(X,A,\mu)$ that is finite, and $f \in L^{\infty}(\mu)$. Also, defined is $a_n = \int_X\,|f|^n\,d\mu$. I need to show that the limit is: $$\lim_{n\to\infty}\,\frac{a_{n+1}}{a_n} = \|f\|_{\infty} .$$   I am stuck on getting started, anybody have any suggestions?  thanks much What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? I have a Beamer presentation with note pages, in which everything renders just fine with pdflatex.   However, when the file is compiled using xelatex (I need to use fontspec), texts in frames after a note page are not visible -- they are rendered in white colour. This problem is reproducible when using Beamer v3.33.  %% Compile with xelatex \documentclass[handout]{beamer}  \mode&lt;handout&gt; { \setbeameroption{show notes} \RequirePackage{pgfpages} \pgfpagesuselayout{2 on 1}[a4paper,border shrink=5mm] }  \begin{document} \begin{frame} A test, A test! \note{ } \end{frame}      \begin{frame} This text does not appear! \note{ } \end{frame} \end{document}   While this problem can be solved by compiling with lualatex, I'm wondering if there's any thing one can do to make it work for xelatex?
