what's the difference between C# compilation setting "/debug:pdbonly" and "/debug:full"?
Should I compile release builds with debug info as "full" or "pdb-only"?
Does a capacitor store charge? There're some easy concepts which I don't get exactly in my mind. I'm afraid I've been studying these things for two years of my engineering but they still bother me. Capacitor is one of them. Can someone explain?    What does a capacitor do? Does it store charges? If so, then how does it do?   I have searched it on Google and Yahoo but didn't find any helpful thing there (for me). So I will be glad if I got my problem solved here.  P.S. I hope that the question would not again be an off-topic, as it always does and moreover people don't suggest then where to go. It's a real sad thing. Why is gradient the direction of steepest ascent? The class of cardinal numbers is well ordered I'm looking for a proof that the class of cardinal numbers is well ordered under the order relation $|A|\leq |B| \Leftrightarrow$ exists an injection $f:A \to B$.  In fact, I've found a very beautiful proof in an article, but I think it's not the standard one. How to create Custom Fields on Standard Objects in the package.xml How can I animate an object fading out? This may sound like a 'first world problem', but I am quite easily distracted by the 'Hot Network Questions' sidebar, as I find them quite amusing and some of them quite intellectual  But where the problem lies is that, even at work, if I google something up and find a solution on Stack Overflow, to some random problem I am working at, I (always) get distracted towards them (Hot Network Questions), and end up reading the whole Qs as well as As of that respective question, and this is adversely affecting my productivity.  Any suggestion would greatly help. Gauge fields and strings: Loop equations What would you call a word that doesn't exist in or translate well into another language? I've run into this situation several times, being a native Spanish speaker.   There are some words you just can't translate into another language. Is there a particular word to describe this?  I'm not refering to idioms.  Also, if its a noun, people tend to use them by surrounding them in quotes. Is this appropiate?  Example:     I arrived at around 5 pm and had some quesadillas.   Edit:  I also meant to cover words that exist in English, but cannot be translated into another language.   Example:      There isn't a word for "drive-thru" in your language. I have a few questions regarding CAN bus load  Is there any derived equation/formula to calculate the bus load?  I need transmit below frames(Assume Standard frame format) at baud rate 500 kbps on the bus 5ms  ----- 50 frames. 10ms ----- 10 frames. 100ms ---- 30 frmaes. Event messages ---- 10 frames.   How to calculate bus load, does anyone knows kindly illustrate the same?  What is the maximum bus load on CAN bus? Spacial curvature and expanding space If we take the analogy that in an empty space the space is just a flat sheet then if there is a single planet or a star then the flat sheet will curve below the planet leaving a curvature shaped like a hemisphere below the object, my question is, Does this curvature change as space expands? $\mathbb Q$ is not the direct product of two non-trivial groups. I know this has been asked before, in a bunch of places, so I expect it to be closed as a duplicate at some point, but I'd like to know if my own proof works. If the proof is incorrect, please limit answers to pointing out the errors. If the proof is correct, then thoughts on improving it would be appreciated.  Prove that $\Bbb Q$ is not the direct product of two non-trivial groups.  —Aluffi exercise II.3.5. My proof Suppose that $\Bbb Q = G \times H$, neither $G$ nor $H$ trivial. First note that $0_G$ is the only element of $G$ with finite order: If $m\ne 0$ and $m\cdot g=0_G$, then $m\cdot(g,0_H)=0_{G\times H}$, contradicting the fact that $\Bbb Q$ has no non-zero elements of finite order. Suppose that for some $m\ne 0$ and some $n\ne 0$, $\pi_G(m/n)=0_G$. Then $0_G=n\cdot\pi_G\left(\frac m n\right)=\pi_G\left(n\cdot\frac m n\right)=\pi_G(m)=m\cdot\pi_G(1)$. Since $\pi_G(1)$ has finite order, we conclude that $\pi_G(1)=0$. Since $\Bbb Z=\langle 1\rangle$, $\pi_G$ maps every integer to $0_G$. Now let $a$ and $b$ be non-zero integers. Then $b\cdot\pi_G\left(\frac a b\right)=\pi_G\left(b\cdot \frac a b\right)=\pi_G(a)=0_G$. As above, this shows that $\pi_G\left(\frac a b\right)=0_G$. Thus if $\pi_G$ is not an injective function, then it must map everything to $0_G$, so $G$ will be a trivial group. The same result holds for $\pi_H$. Since by assumption, $G$ and $H$ are non-trivial, $\pi_G$ and $\pi_H$ are both injective functions, which is of course impossible. I just came onto a project with a pretty huge code base.   I'm mostly dealing with C++ and a lot of the code they write uses double negation for their boolean logic.    if (!!variable &amp;&amp; (!!api.lookup("some-string"))) {        do_some_stuff();  }                                      I know these guys are intelligent programmers, it's obvious they aren't doing this by accident.   I'm no seasoned C++ expert, my only guess at why they are doing this is that they want to make absolutely positive that the value being evaluated is the actual boolean representation. So they negate it, then negate that again to get it back to its actual boolean value.   Is this correct, or am I missing something? Change equation font in Pages During a Pages update which was pushed out a few months ago, Pages obtained the ability to write equations using LaTeX or MathML commands. According to an Apple Support article, the size and color of the equation can be changed ():  The equation appears at the insertion point in your document (or before the selected text). The equation is an inline object, the same size and color as the surrounding text. If you change the size or color of the surrounding text, the size and color of the equation’s font also change.  This does not mention anything about the font used for the equation itself, which seems to be something similar to a Times New Roman font. Is there any way to change the font used, preferably to something like Latin Modern Math? I was considering the possibility of replacing the font file Pages uses with a downloaded Latin Modern Math font file, but I'm not sure what to replace. Could I replace Times New Roman in /System/Library/Fonts/ or something like that? (a) Solve the equation $yu_x+xu_y=0$  with the condition $u(0,y) = e^{-y^2}$. (b) In which region of the xy plane is the solution uniquely determined?     I did the first part but I don't understand how to do part b.  I read   But I don't understand how the argument is based. A more clear explanation is appreciated What is "angle of view" in photography? I read on the :     Focal-length determines the angle-of-view seen through a lens for a   given sensor-size. With a full-frame sensor a lens gives the same   angle-of-view as it would on a 35mm film camera. With a smaller   sensor, the angle-of-view becomes smaller. The crop-factor, also   called FLM, is the ratio representing the difference in equivalent   focal-lengths. So a 150mm on a full-frame DSLR such as the Nikon D700   gives the same angle-of-view as a 100mm on a D7000 since its FLM is   1.5X.      Short focal-lengths show a greater angle-of-view compared to longer   ones. [...]   In layman's terms, what is angle-of-view? Is it the same as focal length? If not, how is it different? How is it used? Why do I need to know about it? What is the difference between "is subject to" and "is subjected to"? I found the following sentence on the U.S. Customs and Border Protection website:     All persons, baggage, and other merchandise arriving in or leaving the   United States are subject to inspection and search by CBP officers.   I would like to know whether changing "subject" to "subjected" will change the meaning of the sentence. How do I avoid the "S to Skip" message on boot? I am working on an Office 365 SharePoint online 2013. Now when I wanted to create a new private site collection, inside the online SharePoint admin center, I did not find the option to create new managed path, as I use to get when creating a site collection inside SharePoint on-premise. So how do I create a new managed paths inside SharePoint online? Why do we say "eat healthy" instead of "eat healthily"? Why do we say "eat healthy" instead of "eat healthily", even though the latter is the only "correct" one, according to the comments in      What came first: ads saying "eat healthy", or the grammatical acceptability of such a phrase?    Merriam-Webster does not consider "healthy" to be an adverb, unlike "quick": , and therefore this question is not a duplicate of For a book cover, I want to write the title vertically (like in Japanese, but using English text):           T T        I H        T I  I  M  L S  S  Y  E   How do I do this without jumping through a host of \vbox and \hboxes?
