Where the hell is it?! I've been looking for ages and I can't find it! I want to find it so I can change the resolution of War Thunder as it doesn't have my native resolution.
I want to buy a new notebook in the near future to play games on it. I'm looking forward for the new Steam for Linux client. My question is that where does the Steam install the games, on the home partition, or in the usr folder, or somewhere else? I do not use pre-release (i.e. beta) versions of either Steam or Ubuntu.
Difference between systemctl and service commands systemd gives us the systemctl commands suite which is mostly used to enable services to start at boot time. We can also start, stop, reload, restart and check status of services with the help of systemctl.  We can do, for example, sudo systemctl enable service_name, and service_name will automatically start at boot time. We can also disable services not to start at boot time.  Is the only difference between the service and systemctl commands that systemctl can be used to enable the start of services at run time? Can we use systemctl on any service? What other significant differences are there? Forms Data Manipulation In Google Sheets I'm trying to develop a solution using Google Forms with Google Sheets that will collect Google Forms data and then automatically divide that one form submission's data into multiple rows of data in another sheet.   I've learned how to QUERY data (thanks to many of you on here) from one sheet to another, but I don't know how to automatically divide 1 row of data into multiple rows.  Here is a  in a visual manner (I will not delete it).   Basically, I have one Google form that collects the following.    Teacher Information (header data) Report Name (header data) Class Information (header data) Student#1 Data (record data: Multiple Form Fields) Student#2 Data (record data: Multiple Form Fields) Student#3 Data (record data: Multiple Form Fields) Student#4 Data (record data: Multiple Form Fields) Student#5 Data (record data: Multiple Form Fields)   I need an automated way to convert that single form response (1 row) into multiple rows (5 rows) each with the same 'header data' but with unique record date.   EXAMPLE Form Data  Header Data  -  Record Date (Student #1)  -  Record Date (Student #2)  -  Record Date (Student #3)  -  Record Date (Student #4)  -  Record Date (Student #5)   EXAMPLE Desired Manipulated Data      Header Data  -  Record Date (Student #1)     Header Data  -  Record Date (Student #2)     Header Data  -  Record Date (Student #3)     Header Data  -  Record Date (Student #4)     Header Data  -  Record Date (Student #5) Few font size-related layout issues I am using a default font size of 26px and stackoverflow's layout seems to not work well with such a large sizes.  The most important issue is that many inputs tend to overflow and partially get hidden below side text. This includes one with login, ‘Title’ and — the most important issue — the editor, which makes writing posts a little painful.  Another important one is that sometimes 'search' field doesn't fit in topbar and jumps lower, being partially hidden by logo. I met that issue on stackoverflow itself only while serverfault &amp; meta display fine (but that may be related to rep or sth).  There's one minor issue too — navbar is too narrow and ‘Ask Question’ jumps below — but this one looks quite nice (maybe it's even intended?).  Screenshot: (click to enlarge) $f$ be an analytic function defined on $\mathbb{D}=\{z\in\mathbb{C}:|z|<1\}$ I came across the following problem that says:  Let $f$ be an analytic function defined on $\mathbb{D}=\{z\in\mathbb{C}:|z|&lt;1\}$ such that the range of $f$ is contained in the set $\mathbb{C}\setminus (-\infty,0]$. Then  $f$ is necessarily a constant function. there exists an analytic function $g$ on $\mathbb{D}$ such that $g(x)$ is a square root of $f(z)$ for each $z\in\mathbb{D}$. there exists an analytic function $g$ on $\mathbb{D}$ such that $\operatorname{Re}g(z)\geq 0$ and $g(z)$ is a square root of $f(z)$ for each $z\in\mathbb{D}$. there exists an analytic function $g$ on $\mathbb{D}$ such that $\operatorname{Re}g(z)\leq 0$ and $g(z)$ is a square root of $f(z)$ for each $z\in\mathbb{D}$.   I have to determine which options are correct. Can someone help in the right direction? Thanks in advance for your time. How to understand Cauchy's proof of AM-GM inequality(the last step) The AM-GM inequality: $$a_1a_2\cdots a_n\leq\left(\frac{a_1+\cdots + a_n}{n}\right)^n$$  the trivial case: $a_1a_2 \leq \left(\frac{a_1+a_2}{2}\right)^2 $ is self-evident.  then cauchy use this fact repeatedly. He get: $$a_1a_2\cdots a_{2^m} \leq \left(\frac{a_1+a_2+\cdots +a_{2^m}}{2^m}\right)^{2^m}.\tag{$\ast$}$$  This is easy to understand, and natural, but next step:  he let  $$b_1 = a_1,\ b_2=a_2,\ \ldots,\  b_n=a_n,\  b_{n+1}=\cdots=b_{2^m}=\frac{a_1+a_2+\cdots a_n}{n}$$  replace $a_1, a_2,\ldots ,a_{2^m}$ with $b_1, b_2, \ldots b_{2^m}$ in $(\ast)$ and simplified both left and right. He get the answer. I can repeat his proof, but I don't know why Cauchy can got this idea. How does he got it? See all my questions across all Stack Exchange sites? Noun form of "affected", meaning things that are affected by X Why doesn't the Java SDK installer set JAVA_HOME? I always wondered why I have to manually set the JAVA_HOME environment variable after installing the Java SDK.     JAVA_HOME=c:\Program Files\Java\jdk1.6.0_12   Visual Studio at least provides a batch file to set these kind of environment variables:     call "c:\Program Files\Microsoft Visual   Studio 9.0\VC\vcvarsall.bat"   Does Java have something similar? I'm trying to make a build script that should simply work after installing the Java SDK. I don't want people to mess with environment variables on their PC. Which choice of line-breaking parameters gives the minimum number of lines When should we use proximity rule in "either/or", and "neither/nor"? According to this , if at least one of the nouns involved is plural then it should take the plural form of the verb. Otherwise, it should take the singular form of the verb. But in the last part it says not all grammars agree to those rules thus proximity rule applies. However, it doesn't explain when to apply the proximity rule and when not to use the former rules. How to efficiently animate 2D scene spanning sprites in Unity? Our game is a 2D point-and-click adventure game.  One of the levels is set in a factory with conveyor belts that span the scene.  The game is hand animated in 2D and so animating these conveyor belts could potentially take up lots of memory since the sprites are as long as the screen (it's an HD game - 1920 x 1080). I'm not sure if tiled sprite shapes can be animated, so I was wondering if there's a prescribed way to handle larger sprite animation like this - efficiently. I don't know how many of you have experienced the  principle when posting questions on SO, but I know I have on a few occasions. And then I just discard my question. So here's the question:  Should we go ahead and post the question?  Of course if it's something stupid like forgetting a semicolon, etc., I would say no... but there are several occasions, like if a data structure doesn't make sense, that at least someone would eventually benefit from the question/answers.  And if you should ask the question, how would you recommend choosing an answer for it? I guess that energy will be used up and, at the end, will contribute to heat the earth, so I see no big differences...  please explain your point of view. I just would like to know if a question or an answer saved draft is visible to someone else, apart from the OP.  Will a copy of a saved draft remain visible even after it has been deleted? Who has access to it? Adding dynamic graphics to an animation Index notation Lorentz transfromation matrix What is included in Wolfram Extras? For holomorphic functions, if $\{f_n\}\to f$ uniformly on compact sets, then the same is true for the derivatives. Let $\Omega$ be an open subset in $\mathbb{C}$. Let $\{f_n\}$ be a sequence of holomorphic functions on $\Omega$ such that $f_n\to f$ pointwise and converges uniformly on any compact subset $K\subseteq \Omega$. Then by Cauchy Theorem and Morera Theorem, $f$ is holomorphic. Let $f_n$ and $f'$ be the derivatives of $f_n$ and $f$ respectively. Prove that $f_n'\to f'$ uniformly on any compact subset $K\subseteq \Omega$.   How to prove? Opt out of moderator election notifications Why do not we ask negative questions without a contraction on the not after the verb? I have found multiple questions touching on this but not a single one that has a comprehensive answer. The information is all there but in little bits.     etc.   Exactly why is "Do not you sleep?" ungrammatical (except in poetry/with artistic license)? I understand that not can't contract after you: "Do you not sleep?" because not can only contract after a verb, and that it always does after do: "Don't you sleep?" but why does it (why must it) contract if it's placed after the verb in a question?   Don't you sleep? (common form) Do not you sleep? (ungrammatical) Do you not sleep? (less common form)
