Computing $\int_{-\infty}^\infty \frac{\sin x}{x} \mathrm{d}x$ with residue calculus None of the physics sensors in my game work, I'm trying to create an AI man that chases after a player, but for whatever reason, he just won't sense the player, I've tried copying and pasting the property name just to be sure, but that's not it. Is there a way to find out if I need a transit visa for Canada? I'm passing through Canada, on my way to somewhere else. I'm staying only a short time.   Is there a website, or some other way of find out out if I need a visa? Irreducible Components of the Prime Spectrum of a Quotient Ring and Primary Decomposition I'm looking for a phrase that describes trying to fix problems caused by underlying issues, with the result of compounding the issue. I usually call this "targeting surface problems rather than root problems", but my terminology is verbose.  Example 1: A government bans buying and selling bananas in the state. Later, it passes a clause allowing citizens to purchase imported bananas.  Example 2: A divided highway is erected with two lanes going in each direction but, since it gets lots of traffic, the shoulders are widened into new lanes. This leaves no shoulder room.  What would be a more concise phrase? Why isn't "Column ordering" available in my list settings? I want to change the column order visible when viewing or editing a list item. I have accessed the "Column ordering" interface via the list settings page on other lists in the past, but it isn't visible in this list's settings. How can I find and replace specific words in a text file using command line? Is there a universal way to turn Windows 7 Aero desktop, all windows, etc into grayscale? I had an option to do this in Intel video drivers on my old laptop, now I have NVIDIA and don't know how to replicate this effect.   There might be a shader or filter that would cause Aero to render stuff into grayscale, but I was unable to find anything. Or must it be explicitly supported by video driver as a bonus? What is a terminal? How do I open a terminal window? How do I use the terminal? Which option is grammatical?        There will be readings from Nikki Giovanni’s and Alice Walker’s writings.   There will be readings from Nikki Giovanni and Alice Walker's writings.      Saying it out loud the latter sounds right, but looking at it the former looks better. So I came across this exercise: Show that if $Y$ is path-connected then the set of homotopy classes $[I,Y]$ of maps of $I=[0,1]$ into Y has a single point.   But I am confused here. If $Y=S^1$ then not all loops are homotopic! I mean, isn't true that $\pi_1(Y)\subset [I,Y]$? Or maybe I don't understand the set $[I,Y]$ well! I want my Ubuntu to look like Mac OS X. Just icon and theme if possible! Is it possible? Is there any way to install slingshot launcher? Optimal estimation of a single parameter given data at different scales Let $A,B,C,D$ be independent normal random variables distributed according to $\mathcal{N}(0,\sigma^2)$ and $E = A+B+C+D$.  The goal is to provide an optimal estimate of $\sigma^2$ given samples of $A,B,E$ but not $C,D$.  In this case optimal refers to minimising the root-mean square deviation of the estimate $\hat{\sigma}^2$:  $$RMSD(\hat{\sigma}^2) = \sqrt{\mathbb{E}\left[\left(\hat{\sigma}^2-\sigma^2\right)^2\right]}$$  I can think of a simple approach to estimate $\sigma^2$ given samples of $A,B$ which is to simply compute the sample variance. Also I know that the variance of $E$ is $4\sigma^2$ so I could compute the sample variance of $E$ and divide it by 4 to get an estimate of $\sigma^2$. However it should be possible to combine the information from both $E$ and $A,B$ to improve estimation $\sigma^2$. Could you outline the approach to use both sets of information? How does Lockable Suspension work? I recently asked a question about . There  told me about the “blow off” feature. Now, I am curious about how the whole system works.   So, can anyone tell me about how a lockable front suspension works, together with features like “remote-lock” and “blow-off”. Accidentally hit "toggle full screen", How do I exit? I'm stuck in full screen in the node editor. Escape isn't working, and I have no menus and no idea how to leave except to quit Blender and reopen the program. Convert String to Integer in QGIS tables better Curve/Text to Mesh generation? The triangulation process of Text to Mesh or Curve to Mesh generates some nasty topology.   I get why, but maybe it could be done a bit nicer? Since text is flat, have ngons instead of hundreds of triangles you'll need to modify anyway?  Another issue is when you then want to use the text as a Volume for particles, which for some reason behave weird when you have unusual topology even though they should be using the volume, not vertex or face positions. A library to convert ANSI escapes (terminal formatting/color codes) to HTML I'm looking for a code library that converts ANSI escape sequences into HTML color, via plain  tags or CSS. For example, something that would convert this:  ESC[00mESC[01;34mbinESC[00m ESC[01;34mcodeESC[00m ESC[01;31mdropbox-lnx.x86-0.6.404.tar.gzESC[00m ESC[00mfooESC[00m  Into this:  &lt;span style="color:blue"&gt;bin&lt;/span&gt; &lt;span style="color:blue"&gt;code&lt;/span&gt; &lt;span style="color:red"&gt;dropbox-lnx.x86-0.6.404.tar.gz&lt;/span&gt; foo   Converting breaks into &lt;br/&gt; isn't necessary, it's just the escape codes that I don't know. I could hack it together myself, but I'd probably miss something important like underlines or mess up how background colors work. I'd rather just sit on top of someone else's code.  Does such a tool (command line linux) or library (perl, python, or ruby preferably) exist? How to get hardware specs of Android device? If I had a very shallow question, then I am sorry. $x,y,z\in\mathbb{N}^{+}$ and$$\frac{x}{y+z}+\frac{y}{x+z}+\frac{z}{y+x}=4$$find $x,y,z$.  I try with AM-GM, just get$$ \frac{x}{y+z}+\frac{y}{x+z}+\frac{z}{y+x}\geq\frac{3}{2}$$  This means that the equation must have a real solution, but can not be sure there is an integer solution.  Let: $x=ay=abz$, then the equation becomes:$$\frac{ab}{a+b}+\frac{b}{ab+1}+\frac{1}{a^2+ab}=4$$  Which makes the problem become non-homogeneous, and seems to become more difficult. I have no more ideas. Could anyone help me? Thanks a lot.
