When I press "safely remove drive" in Nautilus as user to my USB 3.0 Transcent Storejet 25H3 drive it reconnects immediately.  How can I safely remove it without that behaviour?  I think the only solution is to disable the automounting in Ubuntu. I did that now with:   But it is a shame, cause now my external music library doesn't automount anymore.  Isn't there a solution where harddisks don't remount on safely remove?!
I am using Ubuntu 11.10 (64 bits) and I do not want to mount automatically USB thumb drives in my system. I tried the command dconf-editor and gconf-editor but there isn't the icon to disable it in nautilus preferences (apps|nautilus|preferences|media_automount).  Thanks.
Prove $\int_{a}^{b}{f(x)dx}>0$. Let $f\ge0$ be integrable on $[a,b]$. Let $f$ be continuous on $x_0\in (a,b)$ and let $f(x_0)&gt;0$.   Prove $$\int_{a}^{b}{f(x)dx}&gt;0$$  It is easy to see it, graphically, because $$f\ge 0 \Rightarrow\int_{a}^{b}{f(x)dx}\ge0$$  and if $f&gt;0$ somewhere between $a$ and $b$, then the zone of $F$ between those point is "real" (positive) and $\ne 0$.  My problem is, how do I show it formally?  I would appreciate your help. Is a join optimized to a where clause at runtime? The Boolean modifier is not working I'm trying to model an , but it's not going so well when it comes to the magazine of the weapon.   Next to the magazine is a mesh. I want to cut holes in the mag with that mesh. But the magazine just goes invisible or connects with the mesh when trying to execute the Boolean Modifier. I have tested to invert the normals and some other stuff, but it isn't working. Some of the Puella Magi seem to have magical powers related to the wishes that they made. Sayaka has regeneration abilities, and she wished to heal someone. Homura has time manipulation abilities, and she wished to go back in time.  But other magical girls, like Mami and Kyouko, don't appear to have powers related to their respective wishes.  So, is there a connection, or is it only a coincidence for Sayaka and Homura? If it's the former, how do Mami and Kouko's wishes relate to their powers? different font while using url I'm having troubles while using the url command in my bibliography.

Both are basically correct in contemporary English, right? But is one or the other preferable, and if so, why?   (In this case I went with the latter, as it seemed more common (Google)  and I wanted to avoid sounding unnecessarily “archaic”, although I’m not sure whether that would have been the case.

Selecting all files in directory for merging in QGIS Processing? I'm writing a generic script which involves writing shapefiles to a directory which are then merged together. After writing the files out to the Output folder, I'm trying to get the saga:mergeshapeslayers algorithm to merge all the files in the Output folder. I have used the Model Builder and although it is helpful to an extent, I find that it is used for specific purposes whereas I am attempting to make a script for generic purposes.   Code:  ##Test=name ##Select_folder=folder ##Result=output vector  import os import glob  path_1 = Select_folder path = path_1 os.chdir(path)  def function():      output = glob.glob(path_1 + './*.shp')     x = 0      while output[x]:         for fname in glob.glob("*.shp"):             outputs_1 = processing.runandload("qgis:fieldcalculator", output[x], 'Number', 1, 10, 0, True, 1 , "C:\Users\Me\Desktop\Output\\"  + fname)             multiple_0 = glob.glob("*.shp")             x = x + 1          if x + 1 &gt; len(output):             processing.runalg("saga:mergeshapeslayers", output[0], ";".join(multiple_0) , Result)             break         else:             continue  if path_1:     function() else:    pass Just doing this for revision, seems much harder than it should be, should I use $x=\tan u$ ? Any help appreciated. Existence of $f'\in F$ such that $f^{[G:F]}=(f')^n$ for finite extension $F\subset G$ Let $F$ be a field and $u\in F$. Further, let $F\subset G$ be a finite extension and $v\in G$ such that $v^n=u$ for $n&gt;0$.     How would I show that there exists a $\tilde{u}\in F$ such that $u^{[G:F]}=(\tilde{u})^n$?   My first thought was to use the norm map $N_{G/F}(x)=\Pi_{\sigma\in X(G/F)}\sigma(x)$, where $X(G/F)$ is the fundamental set for $F\subset G$. However, I wouldn't know how to continue on this path. Moderncv has a line of empty space between address and phone/email, like this:   MWE:  \documentclass[12pt]{moderncv} \moderncvstyle{banking} \name{Sherlock}{Holmes} \address{221B Baker Street}{London}{U.K.} % Your current address \phone[mobile] {+44~(0)71234 00000}    % Your mobile phone number \email{superdetective@mail.com}  \begin{document} \makecvtitle \end{document}   How do I remove/decrease that space by shifting the phone and email line up?

Force alt + tab to switch only on current workspace in GNOME shell I am looking for a clean and fast method to force GNOME in Ubuntu 14.04 to switch between active apps only on the current workspace when pressing the shortcut alt + tab. Inequality with complex numbers Consider the following problem.  Fix $n \in \mathbb N$. Prove that for every set of complex numbers $\{z_i\}_{1\le i \le n}$, there is a subset $J\subset \{1,\dots , n\}$ such that   $$\left|\sum_{j\in J} z_j\right|\ge \frac{1}{4\sqrt 2} \sum_{k=1}^n |z_k|.$$  I believe I proven have a stronger statement. Is this proof correct, and if so, what is the optimal constant?  My proof. Consider all the $z_i$ with positive real part. Call the real part of the sum of these numbers $X^+$. In a similar way, form $X^-$, $Y^+$, and $Y^-$. Without loss of generality, let $X^+$ have the greatest magnitude of these.  Note that because $|\operatorname{Re}(z)|+|\operatorname{Im}(z)|\ge |z|$, we have  $$ \left(\sum_{k=1}^n  |\operatorname{Re}(z_k)|+|\operatorname{Im}(z_k)| \right) \ge \sum_{k=1}^n |z_k|.$$  But note that $\sum \limits_{k=1}^n  |\operatorname{Re}(z_k)|+|\operatorname{Im}(z_k)| = X^+ + |X^-|+ Y^+ +|Y^-|$, so we have  $$ 4X^+ \ge \sum_{k=1}^n |z_k|.$$ By choosing $J$ to be the set of complex number with positive real part, this proves a stronger statement, because the factor of $1/\sqrt 2$ isn't needed. Can you reduce yourself, crawl into the Tarrasque's airway, and try to collapse its lung by enlarging inside of it? A player tried to use the spell  on his PC while in the mouth of the Tarrasque to shrink himself, then go deeper into its airway and to try to collapse its lung by enlarging himself inside of it. I imagine there's no real rule for this but I felt silly just denying it, because it seemed like a cool idea that you could only probably do with a creature as large as the Tarrasque.  Can you crawl into a gargantuan creature’s mouth or into its airway via reduce/enlarge and attack its brain or internal organs? ADC0808 IC working correctly occasionally I am using  for a project on converting analog signal to digital signal. It has an inbuilt multiplexer using which we have to provide an analog signal to one of the pin. However what happens is ;  Sometimes it latches to a particular value say 1000000 and remains at there no matter how many times Start of Conversion is pressed which should set the inner counter to 0.  Sometimes it gives slightly wrong output off by 100 or 1000 and when I press Start of conversion, it gives correct output, so its not reliable every time.  And most seriously , Suppose the control for multiplexer according to Datasheet are such that input pin 1 should be active, instead, it works only when the input is given to pin 5 for one particular IC and pin 3 for other. I have been trying to fit it in logic since 3 days however each day some new error happens. I have replaced it twice from my college lab and now the technician doesn't want to replace it anymore . What is amiss here ? How can an ordered pair be expressed as a set?
