How to make a process invisible to other users? How could you launch a process and make it invisible to the top command? The process is started by a normal user (not root), and should not be visible to other normal users. Unable to log out of chat. I attempted to log out with the following actions:    This accomplished absolutely nothing since I remained logged in after clicking "log out" on the confirmation page. I then tried logging out of Stack Exchange from one of the network sites and repeated the steps above. The results were the same. I remained logged in no matter which combination of steps I performed.  In fact, the only way I could log out at all was to clear all of the cookies that were set. Always return data from last week's Monday thru Sunday Dihedral group - elements of order $2$ If $D_{n}$ is the Dihedral group of degree $n$ (order $2n$) where n is an odd number, can I then conclude that the numbers of elements of order 2 in $D_{n}$ is equal $n?$  I suppose there are the following types of elements in $D_{n}$: b, $a^{i}$, $a^{i}b$ for some $0\leq i &lt; n$ . Prove $\sum_{d \leq x} \mu(d)\left\lfloor \frac xd \right\rfloor = 1 $ Is it true that the order of $ab$ is always equal to the order of $ba$? How do I prove that if $a$, $b$ are elements of group, then $o(ab) = o(ba)$?   For some reason I end up doing the proof for abelian(ness?), i.e., I assume that the order of $ab$ is $2$ and do the steps that lead me to conclude that $ab=ba$, so the orders must be the same. Is that the right way to do it? ffmpeg - Create a video from image frame with a start and a count I would like to say something like     The boy, Adam's, favorite toy was a bike.   What is the proper way to say this? Many to Many and Weak Entities I have an entity that cannot exist without being defined by another, and I want this entity to participate in a many-to-many relationship.  Example: An artist has an album (the album cannot exist without an artist), the album also has many tracks, but the same track can exist in many albums.  So we have a many-to-many relationship between the album and the tracks.  If the album is a weak entity, then its primary key is a foreign key referencing the artist, thus it cannot be a foreign key to another table representing a many-to-many relationship.  The question is: is it possible to have this kind of relationship in SQL, and if so, how do I express it? In Korea, we learned that we should use the past tense when the subject is an historical event, as in "The Korean war broke out in 1950."  However, I think that when the event continues to affect the present (now), we should use the present perfect.  So I think that we can say 'The Korean war has broken out in 1950.'  Am I right?

I'm an Indian student currently in Singapore as a Research Associate with a TEP valid for five months and have just been selected for an internship in Switzerland this summer.  Is it possible for me to obtain a Schengen visa from the Swiss Embassy in Singapore? What happens if you use Polyjuice potion after saving hair or nails? Suppose you cut a five year old's hair, save it for 10 years, and then use it for a Polyjuice transformation. What age do you turn into: The toddler or the teenager? Why doesn't a \foreach variable work in \draw in an \axis? I'm finding some weird behavior with TikZ's \foreach within an \begin{axis} environment.  This works:  \foreach \x in {-2,-1,...,2} {   \addplot[thick, domain=0.05+(\x*2-1)*pi/2:+(\x*2+1)*pi/2-0.05] (x, {tan(deg(x))});  }   but this doesn't:  \foreach \x in {-2,-1,...,2} {   \draw (\x,-5) -- (\x,5); }   It gives the error  ! Undefined control sequence. &lt;argument&gt; \x                ,-5 l.771     \end{axis}   Here's the really weird part: it only fails when the axis has defined bounds. For example, here's a MWE that works (but doesn't draw anything):  \documentclass{standalone} \usepackage{pgfplots} \begin{document} \begin{tikzpicture}   \begin{axis} % [ ymin=-3, ymax=3, xmin=-5, xmax=5]     \foreach \q in {-2,-1,...,2} {       \draw (axis cs: \q,-5) -- (axis cs: \q,5);     }   \end{axis} \end{tikzpicture} \end{document}   but removing the comment causes it to fail.  Why is this and how can I prevent it?  (My end goal is to draw five segments of the tangent function and their verical symptotes.) Seeking Mobile Data collection software recommendations?
