Not Alt + Tab to find my window Sometimes I open more than seven or eight window. majority of this situation one of them is terminal. also you know that we need terminal during work. So I do not like to press ALt + Tab and after that skip to gain my own window. How many times I should do this!! for an important window like terminal which I need that repeatedly . So I need any key switch which bring terminal for me Not Alt + Ctrl + T, that one open new terminal. I need my own current terminal. Any way you suggest?
Keyboard shortcut to focus on (idle) terminal I would like to know, if there is possible to use keyboard shortcut to focus on first idle (non working) terminal window in unity (13.10)? Something like Ctr+Alt+T, but before opening the new instance of terminal, searching for any idle instance?

Tweaking AStar to find closest location to unreachable destination I've implemented AStar in Java and it works ok for an area with obstacles where the chosen destination is reachable.  However, when the destination is unreachable, the calculated "path" is in no way to the closest location (to the unreachable location) but is instead some random path.  Is there a feasible way to tweak AStar into finding the path to the closest location to an unreachable destination? Unable to install LanguageTool 2.5 extension for LibreOffice 4.2 on Ubuntu 14.04 I am not able to install LanguageTool extension for LibreOffice. Getting exception when I try to install it.   p.s. Somebody says that the solution is installing openoffice.org-java-common package but Ubuntu 14.04 does not have this package in its repository.  System details:  OS: Ubuntu 14.04 LTS  LibreOffice: 4.2 (4.2.3.3)  LanguageTool: 2.5  Java: Oracle JDK 1.8.0_05     Exception message: Is verifying ISOs downloaded from the official website worthwhile? I downloaded the ISO from , selecting the default "Ubuntu Desktop" option.  The website links the page  which gives instructions how to verify ubuntu.  This seems pretty tedious, and I am wondering how realistic it is that there is a problem with ISO downloaded from the official website. I note that the process of verification itself requires me to download software that is new to me, thus introducing another attack vector on me even as I am closing another one.  For what it's worth, I am planning to use Live USB only and not to fully install Ubuntu. Does that make a difference? After reading a couple of answers and comments on some SQL questions here, and also hearing that a friend of mine works at a place which has a policy which bans them, I'm wondering if there's anything wrong with using backticks around field names in MySQL.  That is:  SELECT `id`, `name`, `anotherfield` ... -- vs -- SELECT id, name, anotherfield ... How can I display site logo, name and slogan? Moments of the truncated normal distribution (univariate) away from the mean Centering with \includegraphics not with \begin{figure}? I mess up with things when I try to use the figure-thing: the picture is not appearing with the correct alignment (apparently because I forget the float package). Now I want to use only the graphicx package with \includegraphics. How can I center the \includegraphics without figure?  Not working or doing centering to the document afterwards.  \includegraphics[width=0.5 \textwidth]{./Pictures/r.png}{\centering} \includegraphics[width=0.5 \textwidth]{./Pictures/r.png}\centering I want to make Morrocan-stye pickled lemons, but I was only able to find , and it says:  In On Food and Cooking, Harold McGee suggests that a solution of five to 10% salt is needed to achieve a good North African-style preserved lemon  I make sauerkraut with 20 grams of salt per kilogram of cabbage, so 2%. So lemons taking much more salt than cabbage is surprising and confusing; since they start out acidic, I would expect them if anything to require less salt. I'm not worried about harmful microbes growing; I'm worried about the fermentation microbes not being able to grow. It's my understanding that higher salt concentrations with cabbage not only slow down fermentation, but actually .  had the same issues:  I've never quite understood the need for such excessive salting when making preserved lemons. They still ferment great at normal levels of salt, and you then need to worry less about them being overly salty to use in future recipes. As far as I can tell it's solely from tradition. Also, from checking out On Food and Cooking, it seems that McGee only points out that originally they are done with 5 to 10% salt content. I'm curious where you read/saw that he recommended such?  Does anyone have any text- and/or experience-based opinion agreeing or disagreeing with the &quot;5 to 10%&quot; figure? Best practices for storing UI settings? Where can I get Blender test builds? I know that  provides downloads for official releases. I see on forums that people use newer versions of Blender. Where can I get newer version of Blender (nightly builds, alpha versions... etc). File Save dialog unreadable I just updated my iMac to Mojave, and am still trying to setup my preferences.  I tried dark mode, but did not like it (half of me apps seem to ignore it anyway).  I switched to light mode, but this too has problems. The File Save dialog shows a list of Directories and existing files, but the latter are very light grey, almost indistinguishable from the background.    I have searched the Preferences menu, but can't seem to find any setting to set normal contrast levels like in High Sierra. Probability Math Question...? Bag A contains 3 white and 2 red balls. Bag B contains 6 white and 3 red balls. One of the two bags will be chosen at random, and then two balls will be drawn from that bag at random without replacement. What is the probability that the two balls drawn will the be the same color? Express your answer as a common fraction. Prove $\int_0^\infty \frac{\sin^4x}{x^4}dx = \frac{\pi}{3}$ I need to show that  $$ \int_0^\infty \frac{\sin^4x}{x^4}dx = \frac{\pi}{3} $$  I have already derived the result $\int_0^\infty \frac{\sin^2x}{x^2} = \frac{\pi}{2}$ using complex analysis, a result which I am supposed to start from.  Using a change of variable $ x \mapsto 2x $ :  $$ \int_0^\infty \frac{\sin^2(2x)}{x^2}dx = \pi $$  Now using the identity $\sin^2(2x) = 4\sin^2x - 4\sin^4x $, we obtain  $$ \int_0^\infty \frac{\sin^2x - \sin^4x}{x^2}dx = \frac{\pi}{4} $$ $$ \frac{\pi}{2} - \int_0^\infty \frac{\sin^4x}{x^2}dx = \frac{\pi}{4} $$ $$ \int_0^\infty \frac{\sin^4x}{x^2}dx = \frac{\pi}{4} $$  But I am now at a loss as to how to make $x^4$ appear at the denominator.  Any ideas appreciated.  Important: I must start from $ \int_0^\infty \frac{\sin^2x}{x^2}dx $, and use the change of variable and identity mentioned above If $x\sqrt{1+y}+y\sqrt{1+x}=0$ find $y'$ How would one write object-oriented code in C? What are some ways to write object-oriented code in C? Especially with regard to polymorphism.    See also this Stack Overflow question . Finding an expression for $\tan (a+ b + y)$ which involves only $\tan a, \tan b,$ and $\tan y$. How to find this ?   I'm stuck at $1$ and how to $1$ to change the tangent associated with a,b or c.  I meant this ,everybody.  $\frac{tan(a)+tan(b)+tan(y)−tan(a)tan(b)tan(y)}{1−tan(a)tan(b)−tan(a)tan(y)−tan(b)tan(y)}$ Recent fluid-mechanical experiments by the groups of Couder in Paris and Bush at MIT, mimic a surprisingly wide range of quantum effects. The essential ingredient of these fluid-mechanical systems is a background or pilot-wave that guides the droplets.  Now, surprisingly, a simple analysis of a Bell-type experiment shows that, in the presence of a background field, one of the premises of the Bell inequality, namely measurement independence (MI), is violated. See the paper  (available ). Therefore such classical droplet experiments could violate a Bell inequality. More importantly, if this analysis is correct, background-based hidden-variable theories are admissible, even if they are local (in the sense of ‘involving only (sub)luminal interactions’) and even if they are compatible with free will.   My question: to me the analysis seems fully sound, but maybe there is still an unphysical hypothesis that slipped in ?
