I am looking for a shortcut to copy the path of a file in Mac OS. I generally require it to copy paste in editor.
How can I copy the path to a folder or a file? The Info Dialog doesn't allow me to copy the information that stands there ...    Is there an easy way to do this?
How does $e^{i x}$ produce rotation around the imaginary unit circle? Euler’s formula states that $e^{i  x} = \cos(x) + i \sin(x)$.  I can see from the MacLaurin Expansion that this is indeed true; however, I don’t intuitively understand how raising $e$ to the power of $ix$ produces rotation.  Can anyone give me an intuitive understanding? TeXStudio : Disable auto-completion of parentheses I cannot stand the auto-completion of TeXStudio (formerly TexMakerX) regarding parentheses, braces, etc. I agree auto-completion is useful sometimes, but here it does just not work as I would like. How can I remove it completely?  Under configuration -&gt; completion nothing is checked. From where do I remove the auto-completion of these? Conditions for vertical circular motion If a bob attached to a string is swinging in vertical circular motion, we say that the bob leaves the circular path when the tension in the string becomes zero, but even when tension becomes zero, there's always a component of the bob's weight towards the center of the circle. Why then does the bob leave the circular trajectory? I understand that the architecture of Convolutional Neural Networks (CNN) and Feed forward (FNN) are quite different. And that CNNs use pooling and filters of shared weights over a patch of the image. I am not so clear on the core convolution operator (1):   If anyone could link me to an explanation, I have looked at the Colah blog and Nielsen's online book, and I understand what it is doing but don't understand the convolution operator.  Also, it looks quite similar to the the core FNN function is there and difference? (2).  (1) convolution operator is $a^1 = \sigma(b + w*a^0)$ which is equivalent to:  $a^1 = \sigma(b + \sum^4_{l=0}\sum^4_{l=0}w_{l,m}a_{j+l,k+m})$  (2) feed forward operation:  $a^1_i = \sigma(\sum^n_{j=1}w_{ij}x_j +b_i)$  Many thanks  Sources: functions taken from: Would a Jedi (Sith) clone be force-full or force-less Just seen a picture of Vader Force-choking a trooper. And then I started wondering: what if they had cloned a Sith (or a Jedi). Would the clones have the Force? Specifically, would they have the same Force as the original? How can I create launcher icon for PhpStorm? Looking for a 1000 most frequent english words Is there a free list of 1000 most frequent words used in everyday English? If there is a list with usage examples (as each of those words has multiple meanings for sure, not to cound phrasal verbs), it would be even greater.  Is there something alike, but with phrases? (E.g. 1000 most frequent phrases) Currently, when rep is changed due to the removal of another user account (to undo the rep gain/loss that happened when they up-/down-voted/accepted/were downvoted by you), the associated message is simply "User was removed". I am not the only one who found that message rather cryptic (I had to go search meta when I saw it, and I found my answer in a duplicate, so that makes me at least the 3rd person to not understand it).  I think it's a good idea to add a link to  or some more descriptive text to that.  Edit: e.g.     Another user was removed; reputation changes linked to the user's activity were reverted.   (I can see how it's hard to fully explain the event succinctly, that's why a "what is this?" link to meta or an FAQ question/answer might be better.) What causes the portraits of Wizards to behave interactively? Does J.K. Rowling address how the interactive portraits work? Would a portrait painted after a Wizard/Witch died become interactive, or does the painting of the portrait have to take place during the Wizard/Witches lifetime? If I have a point which I want to hit at the end or during a parabolic arc, how would I calculate the needed x and y velocity? Apostrophes and double quotes don't show up until I type the next letter in Windows XP, when I type an apostrophe ', or  ", no character is displayed.  If I type another character, the apostrophe or dumb quote and the next character appear at the same time.  This happens with double quotes ", apostrophes ' and tilde ~ characters.  What could possibly be causing this?  This occurs in all applications I have tested - wordpad, firefox, ms word etc. Evolutionarily speaking, why do humans have 46 chromosomes How to open nautilus without a desktop? I'm using xmonad, and I would like to open a nautilus window to a certain directory, because I like the convenience of browsing inside an encrypted zip file without unzipping it, which nautilus allows.   however, opening nautilus, even with a path argument starts a desktop on the monitor I'm using (There are 8 xmonad monitors) The desktop is inoperative and renders that monitor useless until nautilus is killed.  Is there any way to open just a nautilus window without any desktop starting? One way to prove that there is an infinity of consecutive powerful integers is to just note that there are infinite solutions to the equation $x^2-8y^2=1$, because clearly $x^2$ and $8y^2$ are clearly powerful. But this uses a bit of theory.  I found this problem under an induction worksheet, and all of the surrounding problems are easy. Is there really an elementary solution to the problem?  All of my attempts have been fruitless.  Note: a number is powerful if whenever a prime $p$ divides it we have that $p^2$ also divides it. What is the time span of The Last Jedi? I masked an image in the UV/Image editor masking section. I then used that mask in the compositor for background replacement. However, the mask size seems to be different. Why is that? Here's a screenshot: Confused between Nested Quantifiers I am reading nested quantifiers. I am confused in between two cases,   1. Existential Quantifier before Universal Quantifier  2. Universal Quantifier before Existential Quantifier   I would be very thankful if someone highlights the difference between them and also give an example.   Thanks in advance. Display historical characters "uͤ", "oͤ" and "aͤ"? It's easy to check that for any natural $n$ $$\frac{n+1}{n}=\cfrac{1}{2-\cfrac{n+2}{n+1}}.$$  Now,   $$1=\frac{1}{2-1}=\frac{1}{2-\cfrac{1}{2-1}}=\frac{1}{2-\cfrac{1}{2-\cfrac{1}{2-1}}}=\cfrac{1}{2-\cfrac{1}{2-\frac{1}{2-\frac{1}{2-1}}}}=\ldots =\cfrac{1}{2-\cfrac{1}{2-\frac{1}{2-\frac{1}{2-\frac{1}{2-\dots}}}}},$$  $$2=\cfrac{1}{2-\cfrac{3}{2}}=\cfrac{1}{2-\cfrac{1}{2-\cfrac{4}{3}}}=\cfrac{1}{2-\cfrac{1}{2-\frac{1}{2-\frac{5}{4}}}}=\cfrac{1}{2-\cfrac{1}{2-\cfrac{1}{2-\frac{1}{2-\frac{6}{5}}}}}=\ldots =\cfrac{1}{2-\frac{1}{2-\frac{1}{2-\frac{1}{2-\frac{1}{2-\ldots}}}}}.$$  Since the right hand sides are the same, hence $1=2$. Using Ubuntu 12.04. is there any way to hide a running process ?  That process shouldn't' display in system monitor,top,htop . There is no problem to remember the process id (PID) so observation of the process can be done easily .but i want to hide the process completely . is there any way ?
